This is the story of Cassie, as she grows from novice to full-blown cum slut. Part 4.
With Katie’s boytoy left in a compromising position, I headed down the hallway.
It was a little past 11pm but I’d had two long naps today and I wasn’t sleepy.
Instead of heading back to my room directly, I took a detour downstairs and into the kitchen. I helped myself to a glass of wine and brought it upstairs. I was feeling horny again but my body was too tired for me to do anything. Instead I put the wineglass on my nightstand and settled down with a book. (I’m not going to tell you which one because the author has since revealed herself as an abhorrent person.)
I sank into the book. Periodically, I came out of my reverie to sip some wine. By the third time, the wine wasn’t even cold anymore. I downed the rest of it and went back to reading.
It was past 4am when I heard a car drive down the street. I heard it drive for a bit, then there was a small latching sound, then a car door shut, and I heard it speed off. I looked out my bedroom window down to the street below. I could just see the top of her head, Katie was walking to the front door.
I listened as she let herself in, then I heard some clattering in the kitchen. After that, I heard a humming. Katie must be microwaving the pasta Matt had made for her.
I headed down the stairs to get a snack and check in with my big sister.
I looked at her and realized that, aside from the fact she was wearing sneakers, she and I were in matching outfits: nothing.
“Did you leave the house naked?” I asked.
Katie jumped a foot in the air. Then she turned and looked at me with a wicked grin.
“No, just short shorts and a cheap crop top. The boys always get a bit carried away, after the second time I stopped bothering with underwear or anything expensive.”
I looked closer. Her hair was disheveled. There were splatterings of cum on her face, neck, and chest. Some was slowly sliding down her legs.
I arched an eyebrow. “Looks like you had a good time.”
She smiled the same wicked grin at me from before. “Oh, ab-so-fucking-lutely. I love Matt, I’ve trained him well, and he’s good to me, but he doesn’t have a dominant bone in his body…..unless I put it there.”
“You needed a break?”
The microwave finished and Katie held up a finger and then almost inhaled the food. Finally she spoke. “If I’m in a relationship, I need to be in charge. But, I….how do I say this….every once in a while I need something…wild and uncontrolled. Matt knows he can’t provide that, so I’m free and clear to get absolutely wrecked every once in a while.”
She started walking towards the stairs. I noticed she was walking gingerly, I guess she’d be fucked so hard she was having trouble walking. “So, what’d you get up to while I was out?”
I gave her a brief overview of everything I’d done with Matt, well almost everything. I didn’t say how I left him presented, I wanted to see the look of surprise on Katie’s face.
“Letting him fuck your ass was probably a bit too nice, but making him clean you out after probably evened it out. Actually, I have something similar in store for him in a minute.”
Oh fuck, was she going to make Matt lick up the cum she had all over her? I wondered briefly if that was how normal relationships worked. Eh, people make their own normal.
I followed Katie to her bedroom door. She stopped and looked at me. “You can watch if you want to, but there’s a price you’ll have to pay if you do.”
I hadn’t been planning on watching, I’d just wanted to see her face when she saw how I’d left Matt. But now I was intrigued. “Oh, I wasn’t planning to, but now I have to know, what’s the price?”
“Well, Matt’s going to be a good boy and clean me up. After that I’m going to uncollar him and he’ll need a reward for all his hard work. If you want to watch, then the price is being the one to give Matt his reward.”
Play with Matt’s dick again? I could do that. I looked at her and simply said “Okay.”
Katie smiled mischievously at me, opened her bedroom door, and flipped on the lights. “What the fuck?” She asked in shock.
I suddenly felt like my clever and embarrassing idea for leaving Matt wasn’t a good one. Belatedly, I realized he’d been stuck in that position for five hours.
“Oh, uh, you said to amuse myself with how I left him. Sorry.”
Katie marched over to Matt and inspected him. She untied his feet and eased his legs back onto the bed. She looked at me and I freaked out.
“You might have gone a bit far, but the cum on his face and the harness holding the dildo in his ass were good touches. But I need him to be able to see if he’s going to clean me up; the dried cum has stuck his eyes shut. Go soak a washcloth in warm water and come clean up his face. I’ll think of a way you can make it up to him later.”
I rushed to the bathroom, and brought back a wet washcloth. I walked up to Matt’s face and slowly, gently wiped his face clean. “Good. Now, Bitch, it’s time for you to clean the cum of six other guys off me.”
Six? SIX? I was so jealous. She’d been gone sixteen hours and had gotten six guys to fuck her and cum on her. The mental image of getting passed from guy to guy flashed through my head and I knew that I was going to have to find a way to out do her.
The look of shock on my face was apparently obvious. “Six guys, three or four times each. He’s got a lot of work to clean up.”
Katie was standing up next to her bed. She uncuffed Matt’s hands and unbuckled the ball gag. Matt got up, stretched his back a few times with a wince, and started licking the cum off Katie. He started with her face and worked his way down. He cleaned her face, her neck, her chest. Once he had, Katie bent over her bed and spread her cheeks. “Good boy, there’s a lot in my ass. Get to it.”
Matt started licking around and into her asshole. Actually, maybe it’d be more accurate to say he was worshipping her asshole. He cleaned it out in a couple minutes. After that, Katie sat on the edge of her bed and he repeated the process on her thighs and pussy.
When he finished, Katie sat up and kissed him deeply. Then she pulled a key out of her nightstand drawer and unlocked the padlock on his collar. “Thanks, sweetie, you always do such a good job. I’m going to take a shower before we go to bed. Cassie is going to give you your reward.”
With that, Katie left the room. A moment later I heard the shower start running.
Matt looked at me. His dick looked even harder than I’d ever seen it. He sat on the edge of the bed, exactly where Katie had been a few moments earlier. He cleared his throat and uttered the first words I’d ever heard from him that showed the slightest amount of independence. “I want a blow job.”
I’d been too transfixed with the entire display to even think of playing with myself. I knelt down in front of Matt, wrapped my right hand around the base of his cock and put the tip in my mouth.
I did exactly what Katie had taught me to do that morning. Matt started moaning as I moved my right hand up and down the shift while sucked on his dick as I bobbed my head. As I did all that, I used my left hand to rub my clit.
I kept up the pace for a while and my jaw began to ache. I definitely owed him for leaving him upside down with a facial for five hours. I took a momentary break to just lick his dick a few times, then resumed blowing her. I kept rubbing my clit but I was too focused on blowing him for an orgasm to start building, mostly just felt hornier and hornier.
I snuck a glance at the clock on Katie’s nightstand, I’d been at this for almost twenty minutes! Finally, I heard his breathing get faster. He started moaning louder. His dick swelling even more in my mouth was all the warning I got before cum started shooting into my mouth. Five massive spurts flooded over my tongue.
Delicious. If they sold it at the grocery store, I’d go through a gallon a day.
I swallowed greedily. I started to slow down but Matt put his hand on my head. “Don’t stop until I tell you to.”
Okay? Guess I’d keep going.
I kept sucking his dick. His legs started to jerk and his body started to shake. I kept going for a few more minutes. He let out a stream of profanity. “Fuck, fuck, yes, don’t stop, fuck, yes, fuck.”
Finally, his dick started to deflate and a small amount of additional cum leaked from the tip. “Easy, easy. That’s enough.”
I stopped and slowly rose to my feet. I turned to leave and saw Katie standing in the doorway.
“Good work, Cass. Go get some sleep. I’ll let you know tomorrow what your punishment will be.”
Punishment? Still? I’d hoped that super long blowjob had been enough. Evidently not.
“Okay, goodnight.”
I went back to my room, got into bed, and turned off the lights. The thought of getting punished was exciting. I thought about everything that had happened that day while playing with myself. After about five minutes of that, a massive orgasm washed over my body. I fell asleep satisfied.
**************************
When I woke up, it was past noon. I got up and felt the familiar and comforting joy of the plug in my ass. I realized I’d had something in my ass constantly for almost a day and a half. Aside from falling asleep in my underwear, I hadn’t worn any clothing for that long either.
I headed to the bathroom. I removed my plug, took care of my morning routine, and hopped in the shower. I washed the plug, lubed it up and put it back inside me. Then I washed the rest of myself.
I stepped out of the shower, toweled dry, and headed down to the kitchen to get something to eat. I didn’t bother putting on clothes. The only people home were, presumably, Katie and Matt. Moveover, walking around naked made me feel depraved and naughty.
I was most of the way through a bowl of cereal when Katie came into the kitchen. She hadn’t bothered to get dressed either. I idly wondered if this was a new development for her or if I’d just missed it all the times I was shut in my room reading or visiting friends.
Katie looked at me. “Good, eat up. We’ve decided on an appropriate punishment for you.”
She headed back upstairs. “When you’re done eating, come upstairs.”
I finished my breakfast, shrugged, and headed upstairs.
Katie and Matt were standing in my room. I walked in and Katie gestured toward my desk chair.
She’d put the saddle on the desk chair. The pair of dildos were back on it, they glistened with lube. “Take a seat,” she commanded.
Intrigued, I walked over to the chair, pulled the plug out of my ass, lined my holes up with the toys, and eased myself down. I felt the dildos slowly fill me up fantastically. I looked at Katie expectantly and noticed Matt’s dick was hard.
Katie put a collar around my neck.I gave her a questioning look. She started talking as she cuffed my wrists to the arms of the office chair, then bound my ankles to the chair legs.
“I did say to be creative in how you left him, but you left him nearly folded over for five hours. To make it fair, I’m going to leave you in a compromised position. Since you had Matt cum on his own face. He gets to cum on yours.”
She ran a rope through a metal ring on the collar and tied it tightly to the back of the chair.
Well, this was going to be…interesting.
Katie reached down and picked up the dial that controlled the saddle. She cranked it up to half speed and the vibrations started driving me crazy immediately. Pleasure and pressure started building and I knew a mini orgasm was going to flash through me soon. I moaned in ecstasy.
I saw Katie do something I’d never seen before. She got on her knees and started blowing Matt. That…distracted me. Was she trying to make it up to Matt too? Her right hand was stroking his dick, her left hand had snaked between his legs and was clearly playing with his ass. Her head went forward and back and she sucked on his dick. Matt was moaning. “Tell me when you’re close, okay?” She kept blowing him.
If I hadn’t been impaled on the saddle, I’d be getting turned on even more with the live show.
Instead the insistent vibrations brought on a mini orgasm. It crashed through me. Another one started building immediately. After a minute or so, it crashed through me as well. I was on my sixth mini orgasm when Matt let Katie know he was close.
They were barely a foot away but she walked him even close, continuing to jerk him off. His dick was right next to my face. I vaguely wondered if he was going to ram it down my throat again. I kind of hoped he would. Instead, she pointed his dick at my face and a few moments later he tensed and started shooting his load.
Katie was evidently better at aiming an erupting dick than I was. The first shot hit me squarely in the left eye. I barely managed to close it in time. The second shot got my right eye. It turned out that cum flying right at me would be the last thing I’d see for the next few hours. Four more spurts hit my face. They got my right cheek once, my forehead twice, and my upper lip.
I opened my mouth to lick the cum off my lip, Katie took the opportunity to put a ballgag in my mouth. I felt her buckle it securely at the back of my head.
Another mini orgasm flashed through me. I could feel a massive one building and knew it’d be here soon.
“Okay, Cass. We’ll see you in a few hours.”
At the same time she said that, my entire body convulsed as a climax flooded through my body. My legs and arms tried to spasm but they were fastened in place. Impaled on a rapidly vibrating saddle, the climax kept going. And going. And going. And going. It was the most intense thing I’d ever experienced. It kept going and I couldn’t handle it. I thrashed as much as my bound body allowed. All that managed to accomplish was knocking me and the chair on our side with the thud, I was still stuck in place. My body kept thrashing as the orgasm got more and more powerful. I blacked out.
******************************************
I woke up covered in dried sweat. I was still strapped to my desk chair. There were three major differences between when I’d fallen and passed out and now. The cum Matt had sprayed on my face had mostly dried. The saddle had stopped vibrating. And someone had flipped me and the chair so that I was on my back.
I lay there in a daze for what felt like forever. At some point, I think I drifted off the sleep.
I woke up sharply as the saddle started vibrating again, stronger this time.
I went through the entire ordeal of mind shattering orgasm and blacking out again.
This happened three more times. I’d wake up, the vibrating started again, and I’d thrash and thrash as an orgasm an order of magnitude more intense than anything I’d experienced before inundated my senses. It’d get so intense that I’d pass out again.
The sixth time I woke up, things were different. I was still bound to the chair, but it was standing up again. The ballgag was gone. And someone had wiped the dried cum off my eyes. I blinked them open. There was a dick about three inches away from my face.
I heard Katie’s voice. “Good timing. You’ll be free in a few minutes, pet. First, open your mouth and suck his dick, he’s almost there.”
The sanity-breaking orgasms had evidently knocked something loose. I didn’t even think, I just opened my mouth expectantly. Matt’s dick entered my mouth. I’d barely started sucking when he came. Four delicious spurts of cum hit my tongue and I swallowed automatically. I kept sucking on his dick until it started to soften. Matt moaned the entire time. Eventually he pulled it out of my mouth with a popping sound.
Katie undid the collar, uncuffed my wrists, and untied my ankles. I tried to get up but my legs weren’t working. I flopped a little but the dildos impaling me kept me in place. Matt reached over and lifted me up. He put me gently on the floor.
“So, do you think you learned your lesson?” Katie asked mockingly.
“Yes” I whimpered, “I’ll be better the next time you’re nice enough to share.”
“Do you have anything else you want to say?” asked Katie.
I blushed as I realized what my orgasm-fried brain was about to say. “Can we do that again some time as a reward and not a punishment?”
“Oh dear, I think I broke her.” Katie replied. “Fine, Cass, the next time our parents are both out I’ll strap you down all over again. In the meantime, I’m giving you a new responsibility to uphold. Any time I tell you to, you have to suck Matt’s dick. Got it?”
Duh, dicks were fun to suck and cum came out of dicks. That deal was like telling a kid they could only play video games after eating all their ice cream. I readily, hastily agreed.
“Too easy. I’m changing it. From now on, you have to do whatever I tell you to do. Now lean over and lift up your ass.”
I tried to comply. But I was exhausted, my legs weren’t working at all, and my arms were much better. I managed to bend at the waist a little and fall to my side. “Good enough. Matt, have fun.”
I felt hands lifting my ass into the air. Then I felt pressure on my hole. With a gasp, Matt’s dick slid right into my asshole. He started fucking me hard from the get-go.
My body was lifted into the air by a pair of strong hands. He bounced my entire body up and down on his dick for maybe twenty minutes.
I think any other time, I’d be driven wild and have had a nice pair of orgasms. But I think I was out of orgasms at least temporarily. It felt amazing but I couldn’t feel an orgasm building.
Finally, Matt grunted and I felt him bury his dick to the hilt in my ass and his cum sprayed the walls of my intestines. He thrust a couple more times for good measure and then lowered me onto my bed and pulled out.
My face was pressed against my comforter, my ass in the air. The rest of my body was limp and lifeless. I felt a new pressure on my recently vacated hole as Katie put an even larger plug in my ass. She flattened my body out so I was face-up on the bed and slid me towards the foot of the bed until my head dangled limply off.
“One last thing, pet. Open your mouth and suck.”
I opened my mouth and Matt’s flaccid dick entered it. I tasted lube and cum. It was all I could manage but I sucked it clean for a minute or two before my mouth stopped responding to my commands. He pulled his dick from my mouth. Lifted up my body and turned me around so my head was on a pillow. I felt Katie cover me with a blanket and I drifted off to sleep before they’d even turned off my bedroom lights.
************************************************
I woke up around 8am the next morning. Sunlight was peaking through my blinds.
About thirty seconds after I’d opened my eyes, Katie opened my bedroom door.
“Mom and Dad will be home in an hour or two. Get cleaned up and put some clothes on.”
