Introduction:

My wife and I want to have a baby with both of us as mothers. Will my big brother help us grow our family tree?
"Hey, welcome, welcome!" I greeted my half brother and his wife.

As Henry and Viviana stepped through the door to our apartment, I took Viv's light wrap and I hugged them both. Close behind me, my wife, Ivory, also embraced our guests, even pecking a quick kiss on their cheeks.

"Woah, Faye," Henry exclaimed, looking us both over, "I thought Viv was making us overdress just for going over to my little sister's for dinner, but you two are making me feel like a hobo."

I blushed and preened at the quick, honest compliment. Henry was actually in a nice dress shirt and slacks, and his wife was wearing a lovely multi-layered blue dress that suited her blonde hair beautifully, but my brother wasn't lying about me and my wife. I was wrapped in a sleek black evening gown designed to look simple, but it hugged me in all the right places and had a slit up one side all the way to my waist.

Ivory was even more stunning in a fiery red dress that had cleavage so deep and wide that it barely covered her areolas and left essentially every inch of that magnificent valley between them exposed. Topping it all off, she had on the double-heart pendant I'd given her for our last anniversary on a long-enough silver chain that it pulled your eye into her bare cleavage every time you looked at her.

"Thanks, bro," I said, suddenly feeling a little shy. "We don't really get out that much these days, so for us, having you two over counts as a real party."

My brother and sister-in-law laughed indulgently at my awkward joke.

"Dinner just came out of the oven," smiled my better half, "so I'll have it on the table in a few minutes. Why don't you go ahead and take your seats and help Faye open the wine."

"Yes, ma'am," Henry grinned.

I smiled to myself when I saw his eyes drawn to Ivory's chest as he answered. I doubt Viviana noticed, though, because she seemed to be equally distracted by my wife's derriere retreating to the kitchen.

"Henry is right, dear," Viviana said to me, licking her lips, "you two do look quite hot this evening. I don't know how Ivory can cook a nice meal and still look flawless like that."

"Thanks." I whispered conspiratorially, but still loud enough for Henry to hear, "You know, we didn't put on our dresses until the messiest parts of the cooking were done, so that helped."

"Right, sure," nodded my brother, "you just wear something else until you get everything in the oven and whatnot."

"Ivory and I are married and live alone." I turned up my nose at him and led the way to the dining room. "Who said anything about wearing something else?"

The way he blushed at that made me grin.

Viviana chimed in, "Ah, yes, dear. It's just like last month when we made those pancakes, and you decided to use the syrup on my--"

"Yes, I get it," interrupted Henry. "You don't need to tell my sister about that."

I had a twinkle in my eye when I held out the moderately priced bottle of red wine and a corkscrew to my brother.

"You know," I said, conversationally, "Ivory and I have found that the sorts of syrup made to go on ice cream also work well for that. One time, she used chocolate and I used caramel, then we had lots of fun mixing them."

Henry nearly stabbed his hand as the corkscrew slipped out of place.

"Thanks for the tip," smiled Viviana. "I'll make sure to put those on my shopping list."

"What are we talking about?" asked Ivory, coming in with bowls loaded with breadsticks and salad.

I'm sure she could easily hear us from the adjacent kitchen, but I filled her in, anyway.

"Henry was just asking what you and I were wearing while cooking dinner. Apparently Viv also goes nude sometimes when cooking, so we were swapping stories about syrup."

My brother made an exasperated groan, then yanked the cork out of the bottle with a violent pop.

"Wonderful," Ivory intoned, putting a hand on Henry's arm. "You've been a big help, Henry. Sometimes I think we could really use a man around here."

"No problem," he mumbled, obviously avoiding looking at her expansive cleavage. "Glad to do it."

We're probably putting it on a bit thick, I mused, but things are going remarkably well so far.

As Ivory went back for the rest of the food, I poured us each a full glass of the wine and we took our seats around the table. After Ivory deposited a steaming dish of homemade lasagna in the center of the table, we began the meal.

We continued to banter lightly over the salad and main course.

"This is fantastic!" remarked Henry, wolfing down the lasagna. "Viv, you've got to get the recipe before we go."

"Why thank you," purred Ivory. "It's just one of the many wonderful things I got from my mother, you know. I'd be happy to share my family treasures with you guys. We are family, after all."

"And don't forget to save room for dessert," I chimed in, with a grin. "My wife has a lot more to offer than the world's best lasagna."

"Mmm, yes, I can hardly wait," said Viviana, looking hungrily at Ivory.

"You guys didn't need to go to all this trouble just for us," Henry said, the next time his mouth was empty.

"Oh, it was our pleasure," Ivory assured him. "Faye and I always enjoy having you come over."

My half brother's wine glass was looking a bit low, so I got up and filled both his and my glass back up.

"Thanks," he muttered.

When my brother had had enough lasagna to satisfy him, the rest of us were still working on ours, so he sat back and looked around. When his eyes strayed to my wife's chest, Ivory chose that moment to slowly wipe up some sauce from her plate with a breadstick. She then carefully licked the red sauce from it and dipped it back in the remnants on her plate. With a subtle glance at Henry to see that he was still watching, she stuck the end of the breadstick well into her mouth and very slowly pulled it out clean before taking a delicate bite from the tip.

Henry blinked a few times and turned away.

"See anything you'd like more of, big bro?" I asked, innocently.

"Uh, no. I'm good," he answered.

We chatted cheerfully until the rest of us had finished our own portions. Seeing that we were done, I got up and got the dessert from the kitchen.

"Double chocolate cake and vanilla ice cream," I announced, as I set them smoothly on the table.

"Wow, you guys," exclaimed Henry. "This is just too much."

"Nonsense," Ivory said. "It's just another dish I got from my mother."

When I came back with the dessert plates and clean forks, I also deposited bottles of chocolate and caramel syrup next to the ice cream. Henry glanced sharply at me, but didn't comment.

"Ah, good," Ivory said, "I thought maybe we'd used up all the toppings the other day."

"Happily, we still have some," I smiled.

I cut a slice of the cake and put it on a plate.

"So, big bro, would you like one scoop or two? There's no need to hold back here."

"Oh, I think I'd better stick to one. I'm not sure I can handle two."

"I think you underestimate yourself," I pouted, as I deposited a small white mound of ice cream on the plate.

Vivivana said, "Quite so. I wouldn't be a bit surprised if you could handle three without issue, dear."

"I say let the man have whatever he wants," commented Ivory, idly playing with the pendent between her own pale white mounds.

"Right." Henry jerked his eyes up to her face, then smiled at me. "I guess I'll take two scoops after all."

I grinned and put a twin mound next to the first and offered my brother the plate.

"Aren't you forgetting the toppings?" mused Viviana.

"I'm sure my brother doesn't need any help to squirt plenty of rich decoration on a lovely white pair like these," I answered.

I made sure to lean over in front of him slightly as I pointedly set the bottles of syrup in front of him. I spotted his eyes briefly flick over to my chest before locking on the bottles he had just heard stories about.

"Uh, thanks, Faye," Henry said, contemplating for a moment before hesitantly picking up the caramel.

I carved out small slices of cake and some ice cream for each of the rest of us, then took my seat again.

After I finished my dessert, I got back up.

"Care for some more wine, big bro?" I inquired charmingly, hovering next to him with the bottle.

"No, thanks. I think I've had enough for now," Henry said.

"Go on, honey," Viviana encouraged him, patting his hand. "I can be our designated driver, if you're worried about getting tipsy."

Viviana and I looked at him expectantly. He glanced at Ivory, but she just smiled at him and slowly licked some chocolate frosting off her fork.

"Fine," he sighed, and held up his nearly empty glass.

I poured until it was well past halfway before he had me stop. I topped up my own glass before taking my seat again, sensing that I would need the courage soon. After he saw that I was back in my seat across the table from him, my brother looked at me and asked the question which must have been building in his mind all evening.

"You've invited me and Viv over; you're all dressed up like this is a fancy date; you fed us some of Ivory's amazing homemade lasagna and chocolate cake, and then you keep waiting on me hand and foot. You're up to something," he accused me, calmly. "And all of you are clearly in on it, too. I know I don't always pick up on this stuff as fast as some people, but even to me, it's pretty obvious that you guys have been acting odd all evening."

Ha! By 'odd,' you mean the way we've been practically throwing you at Ivory? but I kept the thought to myself.

Ivory reached over and took my hand before I answered him.

"Henry, we have a favor to ask. It's kind of a big one, and there honestly isn't anyone else in the world I would even consider asking."

I paused to let that sink in while I gathered my thoughts.

"You've always been there for me," I continued. "You looked out for your bastard half sister all through school, even though you could have just ignored me, or even been mean to me."

Henry frowned sharply when I called myself the B-word. He had beat up a few of the other kids for calling me that in ninth grade. Also, he hated it whenever I pointed out the fissure in our joint family tree, formed by our dad having an affair with my mom shortly before Henry was born.

I didn't pause to let him interrupt me. "And you supported me more than anyone when I came out. Far more than Mom, anyway. You even walked me down the aisle and gave me away when I married the girl of my dreams."

Ivory squeezed my hand. Henry nodded and patiently waited for me to continue.

"So now, Ivory and I have talked about this a lot, and we've decided that we'd really like to start a family."

"We want to have a baby!" interjected my wife.

"Wow, that's great! So, I'm going to be an uncle, huh?" grinned Henry. "You two will make great moms, I'm sure! Of course, Viv and I will support you and help out. You know you don't need to hesitate to ask if there is anything we can do."

"Well," Ivory said, amused, "we could probably use a hand converting the office into a nursery, but that's not the favor Faye mentioned. There's actually something else we need, if you don't mind."

"Of course," he asserted, "just name it."

I gave him a nervous smile. "Maybe don't promise until you know the details. So, you know that science hasn't exactly figured out how to have lesbian couples make babies on our own." Deep breath, "So, what we need is sperm. To be specific, we'd like our baby to be as close to both of ours as possible, genetically, which means we need it to come from a close male relative. Obviously, that means either you or Dad, and..."

Even if I thought our dad would cooperate, I would rather pick literally anyone else in the world than him for this. These three people sitting in my apartment, plus my mom, were the only ones I'd ever told the full reason why I had such a strong reason to feel that way about him, so there was no need for me to finish that sentence here.

Henry nodded and softly said, "Right, of course," but he was clearly still taking in what I was asking of him.

Ivory had some points to say, too. "I've dreamed of having lots of adorable babies ever since I was little. When I agreed to marry Faye, the only reason I had to doubt that move even a tiny amount was that I assumed that it meant giving up on that dream. Of course, we also have the option of adopting, which is most likely what we'll do if you don't agree to help, but Faye and I would really like to have our own children."

Henry nodded at all of that, then looked at his wife.

"Yes, absolutely no objections from me, dear," she affirmed. "The three of us already talked this whole thing through and I'm all for it."

Well, I thought, we might not quite have talked through all of it, Viv.

Henry thought for a tense minute, then smiled warmly at Ivory and me.

"Alright, then. Yes," he declared. "I'd be honored to help you two make a baby. It's not like I would need to do the hard part, anyway. I guess I just need to, you know, donate some sperm and then you guys take it to a doctor for, what do you call it, in vitro fertilization?"

I grimaced slightly and Ivory looked pensive.

"No, not quite," I said.

"It turns out that that procedure is kind of expensive," Ivory explained. "Kind of --as much as a new car-- expensive. So, we were thinking of doing this the...old-fashioned way."

I added, "Ivory and Viv tell me that it's easy, and even fun, with the right guy. And, I actually don't mind Ivory doing that, as long as it's with you. But only if it's you, Henry." I whispered pleadingly, "Which is why there isn't anyone else who could help us."

In the silence that followed that, my brother looked each of us in the eye to see if we really all wanted him to have sex with my wife.

"Yes, dear," Viviana assured him when it was her turn. "I already said I knew all about it and approved."

Please say yes, I pleaded with my eyes when he looked at me. We need you.

"You know I am absotively head over heels in love with your fabulous sister," stated Ivory with a twinkle in her eye, "but don't imagine that I've been subtly seducing you all dinner because I'm opposed to this plan."

"Subtly?" Viviana scoffed quietly. "Doll, you basically gave your breadstick a blowjob while looking right at him. And that gown is a come-fuck-me dress if I've ever seen one."

Ivory puffed out her chest, emphasizing the seductive outfit and looked at Viviana challengingly. "Who says this dress wasn't aimed at you, honey? I've known this little number to work on women, too. Faye couldn't keep her hands off me the first time I put it on."

Our sister-in-law looked away, flustered. Henry cleared his throat.

"Yes, well then," he said, with slightly forced cheerfulness. "Getting back to the baby-- I guess if we all agree, then there's no reason I can't help you out."

Viviana smiled knowingly at that, but I still looked pensive.

Henry frowned. "There's more?"

I took a big gulp of my wine, then looked squarely at my brother.

I began on the tricky part. "There's a condition. I don't ever want to feel like this was a baby that you and Ivory had on your own, but instead, our child needs to be as close to being mine as possible, too. If we could, we would obviously choose to create this baby by me and Ivory fucking on our own, but of course that isn't an option. Still, I really feel like I need to be a part of this, not just a bystander. Which is why I need to be there; not just in the room, but in the bed. I want to be having sex with my wife when she conceives our child."

Henry looked at me strangely for a moment, then looked away embarrassed. He nervously looked back at me and Ivory.

"I'm not...uh, I mean, how would that work? With both of us...all of us...at once? Logistically, er, anatomically..." he floundered.

Ivory calmly picked up the explanation, not quite hiding her amusement at his naivety.

"There are quite a few ways for three or more people to have sex." She winked, "Not to over-share, but we actually have some experience along those lines already, just not with a man. I would be more than happy to describe a few of the very interesting positions we thought we might use with you, but I think the question here is: you and Faye are going to have to get into some quite intimate positions, so are you still okay with this?"

I couldn't meet his gaze when I whispered, "I'm okay with it. This was my idea, after all."

To his side, Viviana nodded vigorously. "Yes," she voted, before even being consulted.

Henry sat back and blew out a long, slow breath. "I can certainly understand where you're coming from, sis. Fuck it. Yeah, alright, then. We can...all do this together. To make a baby. For the two of you."

"I knew we could convince you," said his wife, triumphantly.

"There is one more little detail," Ivory grinned. "Viv should be there, too."

I looked anxiously at my half brother. "We wouldn't want any hint that this is happening behind her back. That...does bad things to a family. And I know she won't mind seeing Ivory and me together."

Viviana's expression went through several tiny changes in rapid succession before settling into a smile.

"Yes, naturally, I'll be there," she rushed out. "I'm glad I get to witness this important moment in our family history. Plus, it sounds like it's going to be really hot."

Henry looked at her questioningly.

"Hey, I know, how about a toast," blurted Viv, holding up her glass.

"Here, here," cheered Ivory.

I picked up my glass so fast that I almost spilled it. Henry chuckled and followed suit.

"To growing the family tree," said Viviana.

"To the family tree," I responded.

After we all had taken a generous drink, my brother was the first to speak.

"So," he inquired, "when were you thinking of, uh, starting to try for a baby?"

"Tonight," purred Ivory, batting her eyelashes at him.

Henry nearly fell out of his chair.

"We've been planning this very carefully and this is the ideal time for her," I smirked. "Besides, just look at her-- there's no time like the present to get it on with my sexy wife."

I leaned over and gave my wife a showy French kiss. My still flustered brother momentarily looked away from such blatantly sensual displays of affection, but then looked back, realizing that this was for his benefit. Moving gracefully, I slid over and sat in Ivory's lap, making sure Henry had a good view when we kissed again. Although I was trying to appear calm on the outside, my heart was pounding already.

Meanwhile, Viviana leaned over and reached into her husband's lap. I assumed she was helping him get in the right mood, but a moment later she held up his keys.

"I'll be back in a second," she said, getting up. "Don't start without me, now."

Ivory kissed my neck while I watched Viv's swaying hips as she left our apartment.

"Isn't this moving a bit fast?" asked Henry, after the door closed.

"No, I don't think so," I murmured, running my hand over my wife's breast. "Like I said, this is the ideal time, so if we don't start now, we'll have to wait a whole month for the next good time."

I noticed that his eyes didn't waver from where I was caressing my voluptuous wife, so I wasn't worried about him backing out at this point. Ivory treated us with a cute little moan when I slipped my hand in and tweaked her nipple under her dress.

Slightly out of breath, Viviana bustled back in carrying her gym bag.

"Okay," she chirped, "I got our overnight bag from where I hid it in the trunk, so we're ready. Let's get this started, shall we?"

"You guys really have planned this all out, haven't you?" mused Henry.

"Yep," said Viv.

She took his hand and pulled him to his feet, so I got off Ivory's lap and led the way to our bedroom. Both Ivory and I had chosen gowns which were open at the back and hugged our asses, so I was pleased to glance back and see my brother admiring the view along the short hallway to the bedrooms.

Standing next to our king-sized bed, I embraced my wife and started undoing the thin straps holding her dress together from the back, while Viviana tossed their bag in the corner. Once I was sure all the attention was back on me and my wife, I kissed my way down Ivory's body, starting on the corner of her jaw and working down her neck and over her clavicle. Meanwhile, my hands slid the straps of her dress over her shoulders, but I deftly kept tension on them so that her dress wouldn't slip down just yet. After planting a kiss on the pendant deep in her cleavage, I shifted back so Henry and Viv could watch as I slowly lowered Ivory's dress, fully revealing her wonderful breasts.

Viviana cooed softly when my wife's soft D-cup globes came into view, and repeated the sound a few notes lower when I pulled down the red dress the rest of the way, leaving Ivory just wearing heels, lacy black panties, and some jewelry. I kept an eye on Henry's reaction, and true to his wife's predictions, he took in Ivory's whole body, but his attention was clearly being drawn to her breasts the most.

After giving them a moment to admire her body, Ivory wrapped her arms around me and planted a slow, gentle kiss on my lips. While we kissed, I could feel her hands on my back, where my half brother and sister-in-law could see her pulling down the short zipper on the small of my back. When my wife let go, I reached up and untied the bow on my left shoulder, then Ivory smirked and grasped the bow on my right. Ivory pulled the last string holding up my dress very slowly, drawing out the moment. When the knot came undone, she let go and allowed the black satin to flow to the floor all at once.

Shyly, I looked over my shoulder, then turned slowly, allowing Henry to see me wearing nothing but some sheer red panties and my tallest stilettos. It felt like my heart was pounding on my ribs like a drum, but I know I was grinning like an idiot, too. Ivory and I stood tall, facing our guests, one hand loosely on each other's far hip, waiting for a reaction.

"Damn," Henry whispered.

He seemed to suddenly remember his wife, but a glance her way showed that she was eyeing the two of us like we were a couple strawberries dipped in chocolate. With my dark hair and the way it felt like I was blushing, I probably resembled that sensual treat.

Ivory beamed, "I think he's actually drooling over us, dear."

Slowly, Ivory and I approached Henry and got up close enough so that our breasts brushed against his arms. She and I shared another kiss right in front of my brother, then we turned our attention to him. I cautiously placed a hand on one of his pecs, before starting to unbutton his shirt, starting at the top. Ivory reached down, unfastening his belt and then his slacks. After I got his shirt off, I helped him steady himself as he stepped out of his pants. Then Ivory knelt and also helped pull off his shoes.

I'd probably seen my half brother shirtless at some point before, but certainly never from so close, and definitely never when I was also naked. Henry was far from a body builder, but he clearly worked out, given the defined muscles on his arms and shoulders. I found myself eager to see more, so I knelt down and put one hand on the side of his boxers at the same time that Ivory did on the other side. When his cock sprang free, I stared at it in fascination.

I guess I had kind of assumed that it would look just like the flesh-toned dildo my second girlfriend had owned, but it was quite different. It was about the same size as the dildo, but the skin had a lot more variation in color and texture, and, of course, right behind it was his ball sack. The way his dick curved down slightly and the way it had moved, I guessed that it was probably about as hard as the rubber phallus had been. All in all, I thought the whole thing looked pretty weird to be a real part of someone's body, but I knew better than to say so. I fought the urge to touch it to find out how it actually felt.

Ivory stroked it a few times and to my surprise, it straightened a bit, pointing more upward and getting slightly bigger. When my wife moved over to coax Viv out of her dress, I stayed behind studying my brother's dick. Looking at his face to see if he would object, I slowly reached up and wrapped my hand around it like Ivory had done. It seemed to jump when I made contact, startling me, but I didn't back off. At first, I kept my touch feather light, but then I carefully put enough pressure on it to sense its texture. When I tried imitating the stroking motion Ivory had used, I marveled at the way it was paradoxically somehow both hard and soft, and slid in a way that was sort of slippery, but not at all slick on the surface.

I was starting to really get into feeling it, when Henry grunted.

"Hn, Faye, you'd better stop."

I jerked my hand away in alarm. "Oh, I'm sorry! Was I doing it wrong? I didn't mean to hurt you."

He actually laughed. "No, you didn't hurt me-- quite the opposite. If you'd kept going, I'm not sure I would be able to hold off until I can get it where you need me to put it."

I blushed, but was pleased that I'd done a satisfactory job touching him. My satisfaction was slightly undercut by Viviana's next words.

"Sorry, but I've been having 'headaches' all week whenever Henry got in the mood. Then, I spent the whole day today teasing him as much as I could get away with without making him pin me down and take me on the spot. I wanted to be sure he was good and ready for tonight," she smirked.

Viviana's dress had joined the others on the floor. She was still wearing a bra and stockings, but I decided we needed to speed up our journey to the main event, so I turned my lust-filled gaze on my wife.

I took her hand and gently pulled her away from our sister-in-law and sat her on the edge of our bed. Then I kissed my way from her erect nipples, down her belly to her hip, while I pulled down her panties. Next, I pulled off her high heels while she shamelessly spread her legs for my brother's eyes. After I shimmied down my own panties, Viv came up and helped me also lose my pointy-heeled shoes, while I peppered kisses around my wife's beloved pussy, which my half brother was about to fuck.

Ivory and I scooted up the bed, trading kisses along the way. When our heads reached the piles of pillows, we looked back at Henry.

"Well, get in here, stud," invited Ivory.

Viv put a hand on her husband's shoulder and kissed him, then bent down and put a wet kiss on the tip of his dick before moving out of his way. Henry climbed on the bed and Viviana took a seat on the chair we kept in front of our vanity.

"So, how do you want to do this?" asked my brother.

"I think we should start simple," I opined. "If you don't mind looking at your sister's body, I'll sit on Ivory's face while you...get to work on knocking her up."

I blushed at my own boldness, but Henry wasn't put off by the suggestion.

"Yes, ma'am!" he grinned. "You're both gorgeous. I don't mind looking at you at all. Either of you."

I sat next to my wife's head long enough for us all to watch Henry put in the tip of his dick, then I swung my leg over and straddled her, facing the action on her other end. Henry started slow, but he pushed in a little deeper with each stroke. Ivory moaned into my cunt, but wasn't satisfied and thrust back into him, encouraging him to go faster. Once Henry took the hint, and increased the force and speed of his movements, my wife started putting her tongue to work on my familiar folds and nub.

"Ah, yes, baby," I moaned. "That's it. Eat me out while my big brother fucks you."

I heard a moan come from Viviana's direction, so I looked over and saw that she was rubbing her cunt through her stockings. I winked at her and moaned again, myself.

I could feel the impact of each of Henry's thrusts through Ivory's body and I loved the way it made her boobs jiggle slightly. Henry seemed to be watching them too, so I reached between my legs and started rolling Ivory's nipples between my fingers, making sure to let them continue bouncing. My wife always liked it when I got rough with her tits, so she rewarded me by increasing her efforts between my legs. She had her hands on my thighs, as she often did in this position, to guide me on when to give her a bit of space to breathe; although this time, she also needed the leverage to keep from getting pushed too far out of place by what Henry was doing to her.

Henry's face began to get screwed-up in concentration, so I thought he might be getting close to cumming. I decided to cheer him on, although Ivory was doing that thing I love with her tongue, which was a bit distracting.

"That's it, big bro, give it to her! Uhn... Pump deep into my sexy wife and plant your seed. Yes, baby, like that! She's so fertile right now, you're going to get her pregnant for sure! Make our baby in her! Yess!!"

Much to my surprise, I was the first one of us to cum. I threw my head back and humped my wife's face in time to the quiver of Henry's thrusts.

When I stopped seeing stars, I found that Henry was still going and Ivory was moaning into my cunt, sending vibrations into my still tingling pussy. I shifted to let her stimulate me from a different angle, but I didn't get off her face.

I'm staying right here until he cums, I reminded myself. This is happening between all three of us.

Viv appeared to be thoroughly enjoying the show, but I was too busy thinking about Henry and Ivory to pay much attention to her. He was clearly all the way inside Ivory on each stroke, but I wanted to know how that felt to her, so I leaned over and slid one hand over her mons. When my ring finger found my wife's clit, my brother's pubic bone crushed my finger into her on each of his strokes, which assured me that Ivory was definitely getting plenty of stimulation on that end.

After retrieving my hand, I got back to work on Ivory's boobs, but this time, I didn't limit myself to her nipples. I worked my fingers in and massaged them the way she liked it when things were getting intense in bed, which they most certainly were then. I also resumed cheering on my brother.

"Come on, big bro! Look at my sexy wife; she's loving having your big, hard dick deep inside her. Now hurry up and give her all you've got, bro! Fill her up with your sperm!"

He was grunting noticeably with each thrust, and I continued trying to talk him into finishing until I felt and saw the telltale signs of Ivory's orgasm. She had basically stopped eating me out, but she still shoved her face into me and screamed her ecstasy into my pussy.

She was still bucking a little erratically a minute later when Henry pushed in deeply and then stopped. For a moment, I was confused at why he had stopped before I realized that he was cumming.

"Yes, that's it!" I called out. "You're doing it, aren't you, big bro? You're cumming in my wife's unprotected pussy!"

When he relaxed and started to pull out, I stopped him and climbed off Ivory's face. They were both panting when I scooped up one of our many pillows and sat next to Henry.

"Okay, Henry," I said, "now you can pull out."

Once he was clear, I helped Ivory lift her hips and I slid the pillow in, under her ass. Henry leaned back on his elbows along the foot of the bed.

Henry looked at me quizzically. "What's that about?"

I grinned. "The internet says this will help all your little swimmers find their way in instead of out. It's a fertility trick."

He chuckled and sat back to look around. Viviana had pulled down her stockings and was unabashedly rubbing her clit, but I was more interested in my brother's wilting dick and the dribble of white cream coming out of my wife's slowly pulsing opening.

"Hey, Henry," I inquired, "were you waiting for Ivory to cum before you? I kind of thought guys always did more of a wham-bam-thank-you-ma'am type of thing."

My brother grinned a little sheepishly. "Well, yeah, of course I was."

"He's always like that," spoke up Viviana. "I'm pretty sure he's made me cum before him just about every time we've fucked. He's a real gentleman, my Henry. There are plenty of other guys who take good care of their women in bed, but I hooked the best one of them all," she bragged.

"Amen, sister," exalted Ivory. "That was great!"

I looked at my brother with open admiration. "Well, I'm no expert on men, but you'll certainly never hear me dispute that my big brother is the best."

I tended to think that all men were pigs, with my brother being the clear and only exception. Henry looked positively bashful at our lavish praise.

I peered down at his dick again. It looked smaller again, more like what it was like when I first saw it.

"Another tip I read on the internet," I said, "was that it usually takes more than one try to get pregnant. Apparently, the more times you cum, the greater the odds of it working." I looked up at my brother's face, "So, make it hard again; we need more cum in my wife, pronto."

Henry sighed and Viviana laughed.

"I don't control it like that, Faye," he explained. "And I can't just immediately go again so soon after cumming. You're going to have to be patient."

"Oh, yeah, sorry," I blushed. "I knew that."

Viv came over and sat on the edge of the bed by Ivory's legs.

"He says that," she mused, "but he's actually not all the way soft. With a bit of coaxing, we can get little Henry ready for duty again in no time."

She cupped his dick in her hand and bent down and stuffed most of it in her mouth. After sucking off most of the juices coating it, she curled her fingers around it, holding it so it was basically straight again. She rubbed her fingers along it, while sucking on the tip for a minute.

After pulling her head up until the tip came out, she looked up at me and moved one of her hands away. I smiled nervously, but didn't hesitate to reach out and put my hand where hers had been.

Over the next couple minutes, my sister-in-law taught me the basics of how to get a man hard. I watched very closely on all the oral parts, like how she swirled her tongue around and licked the underside of the tip, but I limited my involvement to stroking his shaft and such. Much quicker than Henry had led me to believe, he was rock hard again.

"This little soldier is ready to go back into the trenches," Viviana declared, giving his dick another parting kiss.

"I'd say there isn't anything 'little' about that soldier," commented Ivory.

I grabbed Viviana's hand when she got up to leave the bed.

"Don't go, Viv," I smiled at her. "I'm sure you'll be able to see much better from up close. If you come over to this side of the bed, you can even get involved. Your delicious kisses would help knock this little party up a notch."

"Yeah, join us, Viv," implored Ivory.

I leaned in and kissed my sister-in-law lightly on the lips.

"Oh, all right," she whispered.

Henry looked at us both in confusion, as his wife went around and settled in behind me.

"Faye," he inquired, "how do you know what my wife's kisses are like?"

I looked at his wife. "Viviana," I prompted.

She was obviously embarrassed, but didn't look away. "Because she's kissed me before. They both have. And...well, we've done a lot more than kiss."

Henry raised an eyebrow. "You're going to have to explain what exactly you mean by that, Viv."

Viviana pressed her lips together before saying, "It was the night of my bachelorette party. I was, well, intrigued by what the two of them had together, and in one of the party games, they admitted that they've tried having a threesome with another woman. Then, I was kind of wondering what that was like, so I asked them if they would spend the night with me. It was my last chance to find out for sure that I didn't actually like girls before I got married. I'm sorry I never told you."

Henry's expression didn't really change much for a moment.

"So," he reflected, "I guess you confirmed that you like guys. Otherwise you wouldn't have married me."

Viviana cringed.

"Actually," she whispered, "I found out that I like both. I had a bit of a panic the next morning because that night had basically shattered what I thought I knew about my sexuality."

"Fortunately," interjected Ivory, "Faye and I were there to talk her through it. It was a big thing to have to figure out about yourself on such an important day of your life, but we helped her to sort out her true feelings and follow her heart."

Viviana looked earnestly at her husband. "I married you because I love you with all my heart and as earth shattering as it was to find out that I was more than just curious about sex with women, I couldn't imagine my life without you." She smirked and glanced at me, "Also, it helped that your adoring sister had so many passionate, positive things to say about you. I've never heard such things from the lips of someone who wasn't in love."

I think my face turned a new shade of crimson, and I looked at my wife for support.

"I wasn't that..." I trailed off when I saw Ivory silently laughing. "Oh, come on guys! It was a serious moment, and I wasn't about to let a wonderful girl like Viv break my big brother's heart over a silly misunderstanding. That kind of thing only happens in sitcoms."

Ivory snickered and Viv wasn't hiding her amusement either. Henry cleared his throat.

"Yes," he said, dryly, "it's reassuring to hear that your love for me conquered everything else, dear. And I'm glad you finally told me all this. So, I trust that was the last time?"

"Oh, yes, honey." Viviana quickly got serious again. "I would never do anything like that behind your back now that we're married. I didn't really think it was going to go that far that night, and then afterwards, I just couldn't figure out how to work up to telling you that I'd slept with your sister. Can you forgive me?"

"Yes," he sighed. "I forgive you."

My brother looked at me, then looked away, embarrassed.

"Sooo," drawled Ivory, "not to be pushy, but does this mean that you're cool with us playing with Viviana tonight? Judging from the fact that your dick hasn't lost one iota of its rigidity, I'm guessing that the thought of seeing your wife getting intimate with another woman, or two, is something you'd like to see."

He looked back at my wife and found that she had pulled me close and had cupped one of my breasts in her hand and was kissing it from the side. Henry shook his head, as if to clear it.

"Yeah," he conceded, "Viv, Ivory, Faye: I admit that I would like to see you together. But right now, I think we're supposed to be working on making that baby. I'd say I'm ready to go again if you are."

"Oh, I'm ready," Ivory smiled. "But, I think Faye wanted a different position for round two."

I bit my lip anxiously, looking at my brother. "Umm, yes. I was thinking of something that made it feel more like it was my dick knocking up my wife. Ivory will stay like she is, and you do pretty much the same as last time, but I'll be lying directly on top of her in something like a missionary position. It's going to put us a lot closer together though, bro."

I carefully got on top of my wife, putting myself hip to hip and tit to tit with her to show what I meant. I pushed up Ivory's legs with my knees, giving my brother plenty of room to get right up against both of us. I glanced back at Henry to see what he thought of this.

"That's...a lot more contact for us," he remarked, looking between my legs. He smiled, "But, yeah, sure, I see what you want."

Oh dear god, where exactly is he looking? I blushed.

I kissed my wife, relieved that at the very least, he didn't seem to be put off by the idea of touching me more. Viviana scooted closer to us, too, still wearing that same expression of gently smoldering lust she'd had when we arrived in the bedroom.

Once I felt both of Henry's legs make contact with mine, I looked back and shifted most of my weight to my left arm. When his dick got close, I reached back and grasped it with my right hand.

"Allow me, dear brother," I said.

Even though he could certainly see what I was doing better than I could, I took the liberty of guiding his cock towards my wife's pussy. It might have brushed against my own slippery entrance once on the way-- to get my bearings-- but I soon had him lined up on target. He pushed in until I realized that my hand was only in the way, so I released him.

When I turned back to kiss my wife, she had a rather amused expression on her face. I tried to press the smirk off her mouth with my own soft lips, but it just sprang back to the same crooked curve the first couple times. Finally, when I felt Henry's hips press into my ass, suggesting that he was nearing the bottom of Ivory's depths, her mirth transformed into something more like fulfilled lust. I ground my nipples into hers happily.

Henry seemed to be finding his rhythm, so shifted my body to try to line up my clit with Ivory's. I was hoping that I could get us both off by rubbing them together while he fucked her, but instead, I found myself fixating on feeling part of my brother's shaft gliding over my vulva on the way in and out of her. Almost without meaning to, I moved a bit lower, strengthening the contact with his manhood.

Henry had to feel me too, but a glance back showed desire on his face, not disgust. Gleefully, I concentrated on his movement and started to move my hips along with his. Soon, we synced up, creating the sense that I was the one thrusting into Ivory's welcoming pussy. I'd felt something a bit like this before, but this time rather than an artificial plastic strap-on, I was effectively wielding the real thing, armed with potent baby-making sperm.

"Do you feel that?" I asked Ivory. "Does it feel like I'm fucking you as a man?"

She started to laugh, but quickly moaned. "Sure, honey, 'you' feel great. A big, hard cock, round soft tits, and delectable, sexy lips. You're the whole fucking package now, babe."

Okay, maybe it wasn't as convincing as I'd hoped, I admitted internally. But, at least it's just as hot as I imagined. Or hotter.

I didn't let my wife's teasing get to me, I kept up the humping and bent down to suck one of her teats into my mouth. As it always was when she was turned on, Ivory's nipple was a tough little nub suspended on a soft, rubbery cushion. I worked on it gently with my teeth and lips making her moan in delight. Well, Henry's cock might have helped create those moans, too, but that was fine with me. Between moans, Ivory started on the dirty talk.

"That's it baby, fuck me with your big, hard man-cock. Put it deep inside me. I love how much you're filling me up. Don't hold back. Fuck me. Pump that baby-maker inside and unleash your hot cum."

Henry sped up and I followed suit. With the speed and force of his fucking, we weren't perfectly in sync, but I didn't mind that. My thrusts tended to lag behind his a little, which meant that he tended to drive me down into my wife, pressing all of us together each time.

Another feminine hand joined mine on one of Ivory's breasts and it took me a second to realize that Viviana was finally getting involved. I gave her some more space, and she moved in to suckle the other one of my wife's nipples. Ivory was loving being the center of this miniature orgy.

"Ah, fuck!" she moaned. "Yeah, give it to me. You guys, I'm gonna cum! Yes!"

True to her word, Ivory started her familiar orgasmic cry a minute later. When Ivory began to shake, I realized that Henry and I were still bucking into her with no sign that he was ready to cum again. Henry slowed down, and I with him, in order to give Ivory time to recover.

I was getting tired of bending over to suck on Ivory's nipple, plus I think my ass was kind of getting in Henry's way, so I shifted higher. When I started kissing my way around my wife's neck and face, I could still feel my brother clapping into my legs, but he was only barely brushing my vulva.

Since I was no longer making him stay with me, Henry also shifted to a slightly different angle. It was only a few minutes after that that he started using shorter, harder strokes until he finally came with a groan.

After my brother had pulled out, he flopped over on his back on Viviana's far side. Viv and I didn't let up on Ivory; in fact, I shifted down so I could start working over her clit with my tongue. I paused for a moment to consider the taste of their combined cum after the first lick, but quickly resumed eating out my wife. My brother's cum didn't taste too bad, at least in the small amounts I was getting, so I tried not to let it distract me from my goal to give Ivory another orgasm.

"Oh, fuck, baby!" exclaimed Ivory. "Are you eating your own brother's cum from my pussy? God, yes, that's so hot!"

She really seemed to be excited about this latest pushing on the bounds of taboo. Viv also moaned and got a bit more aggressive with Ivory's tits, which quickly helped drive my wife into cumming. She clenched up when she came, which pushed a bit more of his cum out, so I licked that up, almost without thinking.

When Ivory was done cumming, I slid back up to be even with her, but Viviana stopped me and kissed me before I could reach my wife's lips. Her tongue probed briefly around the inside of my mouth before she pulled away.

"You even swallowed, didn't you," Viviana smirked at me, after the kiss.

"Well, yeah, what else would I do?"

Viviana laughed, "Yes, of course, dear. I must say, I'm enjoying this evening even more than I expected. And I haven't even cum. Yet."

We both looked over at Henry and his thoroughly limp dick. It had shrunk to be the smallest I'd seen it. I knew that a guy's penis changes size, but I hadn't expected there to be quite so extreme of a difference between fully erect and fully flaccid.

Henry looked pretty tired. "I really am going to need a while if you're thinking of trying to go again, girls."

"Well," I winked at Viviana, "with both of our spouses recovering from fucking, I guess it's up to me to see to your sexual needs, dear sister."

"Fuck, yeah," gasped my sister-in-law. "I still have dreams occasionally about the way your tongue felt on my clit that night. Please eat me out, Faye."

I just grinned and gently pushed her onto her back and opened her legs. Ivory leaned over and kissed our sister-in-law on the lips, but Henry seemed content to just lie back and watch the three of us.

Slowly and deliberately, I kissed my way along Viv's thighs until I reached her pussy. I ran my tongue around the outer folds of her labia a couple times, teasing her by narrowing avoiding contact with her proud little love button. I stalled like this until she broke away from kissing Ivory long enough to moan out a need-laden plea before I gave her what she really wanted.

Once I started working on her, I didn't hold back, but gave her the best oral experience I knew how to give. After four years of marriage, plus several serious girlfriends before that, I knew quite well how to send a woman to Venus and back without leaving bed. When Viviana reached her first orgasm of the evening, I didn't stop, but pushed her right away into the next. It helped that I remembered that she enjoyed backdoor visitors, so I doubled down and worked her pink starfish with a finger for variety on her second crescendo.

Afterward, Viviana panted, "Goddamn, Faye. That was incredible. Henry tried to do something like that once, but he just doesn't know a woman's body the way a lesbian does."

"I don't think I've ever heard Viv make that sound," mused Henry. "What exactly were you doing down there?"

"Secret lesbian technique," I coyly responded, with a blush.

Viviana looked over at Henry and grinned hungrily. "Yes, indeed. That said, I can see one thing my dear husband has that you can't compete with, Faye, baby."

I also looked at my brother and discovered that he had very clearly recovered. His dick had returned to full size and was standing up, apparently eager for more action.

"Oh!" I chirped cheerfully. "Ready for round three, then, bro?"

"Yeah, I guess so," he smiled. "That was quite the show. Watching you three together does wonders for a man's libido. Shall we get back to the baby making?"

"Certainly," Ivory cooed.

"Actually," interrupted Viviana, "if you guys don't mind, I have a selfish request."

We all looked at her expectantly. She looked a bit embarrassed, which struck me as funny after what we had just done.

"Watching Henry and Ivory," she began, "and hearing all this talk about having his baby has turned me on in a way I hadn't really expected, so...if it's all right, I'd like to fuck Henry next."

"Oh, uh, sure," I blinked at her, "he is your husband, of course."

"No," Viv clarified, "what I mean is that I've caught the baby-fever, too." Looking at Henry with a fire in her eyes, "I know we agreed to wait until we got a house, but all this pregnancy talk has me ready now. I want your baby in me right away, stud."

Henry looked stunned for a moment. "Yeah. Yes, as you wish. I said I would leave that kind of decision up to you, so let's do it."

He glanced at me, as I snuggled up beside my wife. "Sorry, for the delay, Faye, Ivory. I hope you don't mind."

"Not at all," Ivory said.

"Please, go right ahead and knock up your adorable wife, bro."

"Well," confessed Viviana, sitting up, "I'm not especially likely to take today, but it's definitely possible. This is really as much about me joining in the fun as it is about getting pregnant tonight. Odds are, that won't really happen until later."

Henry smiled and started to sit up too, but Viviana pushed him back down. She gave his dick a quick suck before addressing him.

"Your sister has made you do all the hard work so far tonight, honey. Lie back and let me take the lead on this one."

Henry acquiesced, with a chuckle, as his wife deftly mounted his upward pointing rod with practiced ease.

Ivory and I kissed and caressed each other softly, while we enjoyed front-row seats to my brother and his wife making love. I guess I'd always assumed that fucking a strap-on and fucking a real dick would be the same, but I could see that the way she moved had some notable differences from what I'd experienced. I took mental notes the whole time she was riding him, learning what I could about how the other team played this superficially familiar game. I got so engrossed in watching every detail of their union, that at some point, Ivory had to firmly pinch my hard little nipple just to remind me that she was there, too.

True to form, Henry held out until his wife came before unleashing inside her. Afterward, they lay together in a sweaty, intimate pile for a while, which reminded me a great deal of the way Ivory and I recovered together after a good romp. When they pulled apart, I helped Viviana lie back with a pillow under her ass, just like Ivory.

"That was beautiful," sighed Ivory, taking Viviana's hand. "Welcome to the baby-making club, Viv."

"Thanks, Doll."

"I guess 'little Henry' will need to recover again, huh?" I asked, looking at my brother's dick.

"Yep."

"Then," Ivory purred, "how about Faye and I put on a little show for the big guy. That worked well last time, and we just got to watch you two together, so I'd say it's only fair that you get to see us show off our love, too."

I smiled shyly at my brother and Viv before kissing my wife. Ivory and I quickly became engrossed in making out, nearly forgetting our audience. When her hand slid between us and started to massage my clit, I decided that I needed more, so I sat up and tucked one leg under Ivory's leg. From there it was just a small shift to bring our clits together in a classic tribadism position.

"Aren't you worried about my cum getting in you?" asked my wide-eyed brother.

I just shook my head with a crooked smile and pressed into my wife.

Remembering what I'd seen in porn, I angled my body to let Henry and Viv have a clear view of our point of sexual contact before starting to roll my hips, sliding my sex over Ivory's cum-soaked pussy. Ivory reached up and grasped the nearest of my boobs, moaning and playing with it, as I settled into a familiar, intimate rhythm.

We were both pretty well primed from everything that had happened in the last hour or two, so despite me not rushing, it was only a couple minutes before I came. As soon as I felt my orgasm start to fade, I dropped down and rapidly ate Ivory out until she came, too.

When I climbed back up to kiss my wife, I noticed Viviana fingering herself pretty energetically, apparently not quite done getting herself off on our brief show. Henry was very slowly stroking his cock, which was clearly up and ready for more. After sharing the flavor of the new combination of sexual juices with Ivory, I turned a hungry gaze on my brother.

"Excuse me," I whispered, as I leaned over Viv, putting my face close to my brother's crotch.

I very slowly pushed Henry's hand away from his cock and gave it a gentle stroke of my own. After staring fixedly at it in my hand for several more pumps, I leaned closer and put the end in my mouth. From handling it and from eating out Ivory, I had quite a good idea of what it would feel and taste like, but it was still remarkably thrilling to have my big brother's cock in my mouth. I tried to imitate what Viviana had done, but I was forced to back off before I got nearly as deep as she had.

I guess that takes practice, I mused, as I sat back.

The others were all staring at me with various curious expressions on their faces. Ivory was pretty much smirking; Viv's expression could only be described as eager leering. Henry had a somewhat dopey smile, but I thought I saw a hint of doubt or confusion, too.

"Yes," I blushed. "I'd say you're ready."

Henry cleared his throat. "Yes. Yes, I am. So, uh, what's next?"

He got off the side of the bed and walked over to stand at the foot, looking back and forth between Ivory, Viviana, and me. I bit my lip nervously for a second, then rolled over, squeezing myself between Ivory and Viviana. Once I was lying on my back between them with my ass on top of the pillows under them, I spread my legs over theirs and looked my brother straight in the eye.

"My turn," I stated boldly.

Viv made a tiny, suppressed squeal of excitement and Ivory kissed my shoulder, but I kept my gaze locked on Henry. He was looking me over with obvious lust, but was also hesitating.

I gave him an uneven smile. "I guess I've got baby-fever, too, big brother. Ivory's and my cycles are nearly lined up, so today also happens to be a very good day for me to try for a baby."

He couldn't seem to take his eyes off what I was offering him, but he wasn't convinced yet. "But, Faye, we're brother and sister. Aren't you worried about, well, mutations and stuff?"

"That's another little item I read up on online," I said, softly. "The odds of birth defects and serious disorders from sibling incest are much lower than most people assume. It's more like extremely rare issues become merely rare in such cases. Plus, we aren't even full siblings, so this is much more like cousin incest, which used to be super common a few hundred years ago. It'll be fine."

I put a hand on my belly and rubbed it slightly. "I want your baby in me, big bro."

Viviana started to chant in a whisper, "Do it. Do it. Do it."

I gave him my best puppy-dog eyes. Ivory joined in the chanting, too.

"Do it. Do it. Do it."

Henry finally chuckled and waved for them to stop. "Okay, okay. If you guys are sure, I'll fuck Faye, too."

"Yes!" jubilated Viviana.

Ivory snickered, "I knew all along you had the hots for your big brother, babe."

I blushed and tried to look away, but pinned between my voluptuous wife and excited sister-in-law, I didn't have anywhere to hide. They both snuggled up against me as Henry carefully climbed over the tangle of legs to reach me. Once he was poised to enter me, he stopped and looked at me in concern.

"Faye, isn't this your first time? I guess I'd better go slow and--"

"Just fuck me, already! I lost my hymen ages ago and I'm super wet from cumming several times just now, so I'm more than ready."

He put the tip in me very gently, but I was in no mood for half measures. I wrapped my legs around his waist and pulled him sharply towards me. He resisted the pressure, so I only got a little bit more of him in me, but he finally seemed to believe that I wanted him, so even after I relaxed, he started to piston deeper and deeper into me.

It was wonderful. I'd had a dildo in me like this plenty of times, so the physical sensations weren't exactly new, but in a way that was hard to really describe, this was entirely different. The nearest I can explain it, is that it is like the difference between rubbing your own clit and having someone else rub it for you. The same, but also somehow so, so much better.

I could tell he was still being much gentler with me than he had been with Ivory, but he was finally actually fucking me.

Ivory and Viv were all over me, too, kissing, licking, and rubbing me in all sorts of nice spots, but when Henry's hand found its way to my breast, they both gave way to him in that area. I also reached up and cupped my brother's firm pecs, feeling how different they were from a woman's soft breasts. I toyed with one of his nipples, partly imitating what his hand was doing to me until he chuckled and I sheepishly recalled that men didn't really get much enjoyment from that kind of touch.

Finally, Henry bottomed out inside me, which sent a jolt through me that I'd never gotten from a dildo.

"Ah, fuck, bro! Yes!" I moaned loudly. "You're bumping into my womb! I can't believe you're really fucking me, big brother. You're going to fill me up with your hot baby-making seed. I'm going to have my brother's baby growing inside me soon!"

"Yes, do it, baby," Viviana cheered us on. "Oh, god, you guys are so fucking hot together!"

Henry gave up trying to go slow for my first time and increased his pace. Ivory and Viv continued to touch us and encourage us for either side.

I was just thinking that I didn't think I'd ever been so turned on when Henry leaned in and kissed me on the mouth. I moaned and eagerly welcomed his tongue, sharing my first willing straight kiss, while he continued making love to me. This quickly proved to be too much for me and I came with the force of a tidal wave. My big brother rested his stuble-rough cheek against mine and continued to fuck me as my orgasm crashed over me. Almost as soon as that one had finished, I began cumming a second time.

I unleashed a long wordless cry with this second orgasm. I almost missed it, but near the end of this one, I felt a small but definite sensation inside me, which I realized was Henry's cum spraying against my cervix. I promptly recaptured my brother's lips with mine, pouring my affection and excitement into the frantic kiss.

When Henry had finished cumming, he relaxed, allowing the majority of his weight to rest on me. As we lay together, panting, we each turned our heads to accept some passionate kisses from our wives.

"Thank you, Henry," I whispered, when we had all calmed down some. "I love you."

He gave me a peck on the lips. "I love you, too, Faye."

Ivory nuzzled me gently with a smile. "I had a hunch you were going to try to pull something like this, honey, but I can still hardly believe you two really fucked. And you deliberately did it on an unsafe day, too. Damn that was sexy."

"Amen, sister," purred Viviana. "I'm jealous-- I wish I had a brother or sister to commit incest with."

Henry and Ivory laughed at that.

Henry's soft cock slipped out of me, leaving me suddenly feeling empty where I had recently been so full. I sighed as he climbed off me and scooted Viviana over so he could snuggle in between us.

"Well, ladies," he said, "this has been incredible, but I think I'm beat. You girls have tapped me dry."

"It's just as well," murmured Ivory, "our neighbors are probably all jealous of all the noisy fun we've been having at this point."

"Oops," I winced. "I guess we'd better clean up and get some sleep."

Ivory and Viviana both rolled on their sides sandwiching my brother and me between them.

"Yeah, honey," yawned Ivory. "I guess so."

When Henry's arm wrapped around me and Ivory, I found myself trapped in the middle of a sweaty, sexy set of spoons.

"Or maybe we can clean up in the morning, dear," mumbled Viviana.

With a smile, I wiggled around to fit more comfortably in the middle of my family and drifted off to sleep.

-----------------

Epilogue

One year later, three topless women took a seat on my couch, while my brother hovered anxiously, but uselessly, nearby. On the left, Viviana breastfed eight-week-old Penny. I was in the middle nursing Hunter, who had already grown into his three-month-old clothes. Ivory had been the last of us to get knocked up, so tiny little Josie sucking her teat was barely more than a week old.

This was the first time we'd had 'Uncle' Henry and Aunt Viv over since Josie had been born, so this was the first time all the three of the half siblings had been together. Obviously, Ivory and I were exhausted from dealing with two infants who were on very different schedules, but it was still exciting to have the whole family together. Henry had gotten to hold both of our little ones right after they were born, but it was Viv's first time meeting Josie in person.

After the little ones had finished feeding, we changed them and laid them all side by side in the crib in the nursery. Before falling asleep, Hunter showed off his motor skills by grasping Penny's sleeve with his stubby little fingers.

"Awww," softly cooed the three of us mothers, reflexively.

"My little man is going to grow up to be just like his daddy," I whispered fondly. "I know he's always going to watch out for all his bastard little sisters."

Henry, who was watching every move, could not have looked prouder as we all carefully tiptoed out of the room. Once outside, I pressed my bare chest against my brother and nuzzled him affectionately. Ivory gently moved in next to me, inviting Henry to feel up both of our expanded sets of tits.

"Mmm, hey, big brother," I moaned. "In case you forgot, Ivory and I plan to have lots and lots of kids."

Henry gasped quietly, and a moment later I felt a familiar bulge in his pants poking me in the thigh.

"I think that can be arranged for a couple of sexy MILFs like you," winked Viviana. "Don't you agree, dear husband?"
