Cora and Kevin become reckless in their fucking, allowing their mother to catch them. All characters are 18+
And just like that I was having an ongoing sexual relationship with my sister.
I suspect most people reading this will be thinking something like “what a lucky guy, I wish I were him!” at this point. And that’s not entirely unfair. I was regularly getting the most insane head imaginable from my extremely attractive mother. My bombshell sister was insatiably hungry for my cock and letting me slam her tight little pussy at every available opportunity. I had two beautiful women desperate to fulfill my sexual needs, and the only limitation was my ability to produce cum and get them alone. I’ll admit, that part was great.
But it was also one of the most stressful periods in my life. Cora knew about Mom and me, and she seemed to be ok with it. We had a pretty serious talk the day after our first encounter, and while I think part of her wanted me all to herself she was adamant that I needed to keep making sure our mother was taken care of. Of course she was even more adamant that I keep taking care of her. My worries that she would end up regretting what we did were wholly unfounded. That meant I could be a little less careful in fooling around with Mom. But Mom, alas, did not know about Cora and me.
We wanted to tell her, both of us agreed she had a right to know. But how do you start that conversation? “Hey Mom, real quick before you give me that sloppy toppy. You know Cora, your daughter, my sister? Well, she and I are having wild monkey sex every time you aren’t around. Just a heads up, now lemme devour that box.” Yeah, not exactly the sort of revelation you can make casually.
And we were, too. Having wild monkey sex any time Mom wasn’t around, that is. With the barrier broken down I found myself rock hard 24/7 for my sister’s perfect cunt. Our sexual compatibility was off the charts, and we both had a deep and abiding hunger for one another. Nutting inside my little sister was fucking addictive. More than sexually pleasurable, it provided a deep emotional satisfaction. Any time Mom went out to run errands, if we were home while she was at work, if her well-meaning friends were taking her out to meet guys again, you could bet that my sister and I were back home banging each other as hard as physically possible. There were a few days where Cora and I would fuck in the afternoon then Mom would come visit me at night. The first time was harrowing. In the pit of my stomach I knew Mom would be able to taste my sister on my cock and everything would explode.
She didn’t, though, and as is so wont to happen the more my sister and I got away with it the more complacent we became. I think both of us got off a little on the risk of getting caught. We’d fuck until we heard Mom’s care pull into the driveway. We’d grind on each other when Mom was still home with us. Once Cora joined me in the shower and had me fuck her in the ass while Mom was still sleeping. I can’t even count the number of times we’d have dinner with my cum leaking out of my sister’s freshly-fucked cunt. Mom never caught us, and we never did figure out how to broach the subject of our relationship with her and come clean.
So, of course, it was now our mother’s turn to catch us in the act.
There we were, a perfect Saturday afternoon. Cora and I were sitting on the couch, some show running in the background while we doomscrolled through our phones. Suddenly, Mom pops her head in from the kitchen.
“I gotta run out for a few hours, you kids don’t burn the place down while I’m gone!”
My sister and I both nod in assent. I look at her. She looks at me. We both smile. Oh yeah, we’re fucking once Mom has left. Mom puttered around for another few minutes, before finally heading to go do whatever she’s going to do. Once I hear the door close I turn to my sister, but she’s already on top of me. Her mouth is on mine, devouring me, while her hand fishes my rapidly hardening cock from my jeans. Our breathing was fast and needy as Cora broke the kiss.
“We shouldn’t do this here, Mom just left.” I panted.
“You heard her, she won’t be back for a few hours.” My sister replied. She slid off the couch to kneel between my knees. “And I need you inside me right fucking now.”
I could only lean my head back and moan as she began kissing my shaft and tonguing my pisshole. Bathing my cock with her saliva, she pulled my testicles out of my pants and began kissing those too. Her lips were heaven on my nuts as she stroked me to full hardness. I’d had girls play with my balls before, but no one did it like Cora. She was gentle, but not too gentle; firm, but not too firm. She kissed my beans on at a time, then licked my entire sack. She massaged my testicles just right, teasing them with her fingers, plumping them up till they were heavy with sperm, then put them in her mouth and sucked them as if the seed could come out through my scrotum. I leaned back powerless. It felt good, but it was also an activity of trust. The slightest misstep would mean catastrophe for my family jewels, but Cora always handled them with reverence and joy. She didn’t do it for me; she did it for her. She took joy in it. She did it all one-handed, too, her other hand in her pants toying with her muff. The wet sound of her stirring her own pot enhanced my arousal.
“I love how hard you get for me, big brother.” She gasped at me. Spit and precum dripped from her mouth. My cock was a sloppy, wet mess. Electricity passed between us as she stared intently into my eyes. She looked like a wild animal, a sexual goddess. I loved her.
“I love the things you can do to me, little sister.” I replied. We were both such fucking perverts. Instead of being ashamed of our blood relationship it just fueled our mutual lust. She laughed and rose to her feet. I stared mesmerized as she did the classic hip wiggle of a girl squirming out of her jeans. Reaching out, I placed my finger between her legs, rubbing her clit through her polka-dot panties and eliciting a delighted moan. Her nub was stiff and throbbing in the softness of her vulva. I could feel how wet she already was, and loved the way the material clung to her perfect puffy lips as I took my hand away.
Hooking her thumbs into the waistband, Cora soon had her panties on the ground as well. Fluid clung to the gusset as she removed them. Stepping out of her bottoms, she pushed me back onto the couch and straddled my lap. She gripped my cock and rubbed it against her exterior, combining our juices on my sensitive cockhead. I slid without friction along her slit. We moaned and thrust our hips at each other.
“I can’t wait to feel you cum inside me.” She whispered huskily into my ear, “I want you to flood my pussy with your jizz. It makes me feel so connected to you. My cunt is so hungry for your cock.”
I bit her earlobe gently and thrust my hips. My sister held me perfectly aligned with her opening so my tip breached her. She was so wet, but still so tight. We moaned into each other as she slowly lowered herself onto my lap, sliding inch after inch of incestuous brother-cock into her naked pussy. Cora was so wet, everything was lubricated perfectly for insertion. But the gorilla grip of her vagina meant there was still resistance. It took a bit of force, but there was no pain for either of us as I penetrated her completely. It was a perfect union, plumbing my sister’s depths was pure bliss.
Soon, I felt my tip gently bump her cervix as she bottomed out on me. Cora used her arms, legs, and cunt to cling tightly to me. I rotated my hips to graze her g-spot. She yelped and jumped slightly, then settled back down and began grinding on me. Pressed so close her tits weren’t accessible, but I didn’t mind. Wrapping my arms around her waist I grasped her bottom in my hands. As she rode me I spread the globes of her ass apart, teasing her sphincter with my fingertips. I knew this drove her wild.
“Fuck yes it feels so good!” She moaned into my ear, the pulsing of her cunt on my dick confirming her words. Reaching ever lower I ran my fingers over where our bodies were joined, coating them with her flowing juices, before smearing her tight little asshole with her own natural lube. I thrust up into her, imprinting my cock onto every inch of her insides, as I gently worked my index finger into her asshole. Cora’s movements grew less controlled as I pressed her buttons. She leaned back slightly, giving me easier access to her ass while also grinding her clit into my pelvis more effectively. As I began to feel my finger pressing into my cock through the wall separating her birth canal from her bowels, I knew Cora wouldn’t last much longer.
Neither would I, of course, but we’d already gotten pretty good at timing our orgasms to match each other. As shudders wracked through her body I knew we’d both be popping off in a moment. I pressed my face into the fabric of her shirt, inhaling her arousing scent as I enjoyed the feeling of her breasts on my face. Her nipples were diamond-like points, and I could feel every breath jiggle through the rich tissue of her boobs. Kissing her cleavage I placed my mouth over her left breast. Heedless of her top, I sucked the entire areola into my mouth and licked it. Cora gasped. My tongue flicked her nipple. She ground her clit into me and squeezed my cock like crazy. Ever so slightly I bit down on the firm, tender flesh of her breast, taking the nipple between my teeth and pulling it. Cora yelped and moaned. I could feel her juices leaking onto my balls.
Cora slammed down on me and began spasming. I thrust up into her and held her tight. We both grunted in pleasure. Just as I felt my nuts tense up and begin to unload into her waiting body, I heard the creak of a door and words float through the house.
“Sorry guys, I forgot something, going back out in just one...minute.”
I pulled my head from my sister’s chest and whipped it around as best I could. Cora too was looking in the direction of the sound, her eyes like saucers. Standing there staring at us was our flabbergasted mother. Her car keys fell to the floor as a look of pure horror washed over her face. She was facing the back of the couch, so the full details of our copulation were not visible to her. Still, from our position and the wet noises we were making it must have been obvious. I didn’t know what to say. Mom, clearly, was speechless. It was Cora who spoke, saying the last thing I ever expected in this situation.
“Oh fuck Mom, he’s filling me up so good. He’s cumming in my tight little pussy and I fucking love it! Cum inside me, big brother! Fill my slutty cunt with your jizz! Fuck your hot load is making me cum tooooooooo!”
This broke the spell our mother was under. She was already crying as she fled the room, her footsteps pounding up the stairs and the door to her bedroom slamming shut with a crash. Despite this, my balls were still retracted up into my body, pulsing as they shot thick hot wads of sperm up into my sister’s nubile womb.
Cora rode out her own orgasm on top of me. It was a big one. Her whole body shook as she clamped down on me, holding on for dear life in violent convulsions of unrestrained pleasure. I was in shock, but as soon as her climax was over she rolled off of me onto the couch.
“Fuck.” She said. “Fuck, fuck, fuck.”
I could only stare vacantly in agreement. A glob of cum oozed out of her pussy and onto the couch.
“Fuck. You need to go talk to her.” Cora said. Her breathing was ragged and her eyes wild. She was looking at me seriously, but the way her thighs were clenched together told me she was still riding out aftershocks.
“What?” I responded.
“You need to go talk to her, let her know that it’s ok and that you still love her.”
“You think that’s the fucking problem right now?” I asked.
“God, men are so dense. Yes! Yes that’s the fucking problem! She’s heartbroken right now, and probably super jealous. She probably thinks you’re going to replace her with me, and that she’s going to lose you.” My sister’s voice grew quiet. “That’s how I felt when I caught you two.”
Cora looked up at me with her perfect eyes. Love, concern, and a certain accepting peace were all visible in them.
“You need to go let her know that she won’t lose you. You need to take care of her. Take care of us. You need to give her what she needs. You can’t hold anything back from her. You understand what I’m saying?”
Cora pushed me slightly to get me off the couch. I stood, evaluating her words. They rang true. Mom had already lost so much, she needed to know she wouldn’t lose us too. I slung my soggy cock back into my pants and zipped up. I was still a mess, I smelled like sex, there was a large wet spot on the front of my jeans. But this couldn’t wait. My sister stared after me as I ascended the stairs to comfort our distraught mother.
