ROOMIES

There comes a time in every man's life when he has to accept that his sister is a sexual being. For me, that time came when my sister and I were sharing an apartment in college. Specifically, that time came when my dick was shoved balls deep all the way up her big butt in our living room.

It was my third year of college and I had finally moved out of the dorms and found a nice two bedroom apartment. The problem was I couldn't find a roommate. I didn't have many friends and the few I had were already living in other places.

However, my little sister Jenna had just graduated from high school and was planning on going to the same school as me. I asked her if she wanted to live with me to save some money. She didn't really want to live in the dorms anyways, so she agreed.

I grew up in Missouri -- part of the fucking Bible Belt. My parents were very religious, and they kind of messed me up. I lived a sheltered life growing up, and the far right religious atmosphere had me constantly scared that most things I wanted to do would send me to hell. My parents had me so terrified of sex that I never even had a girlfriend until I left for college.

When I started college, the change was fairly quick. I started rejecting most of my preconceptions about the world and started living how I wanted to live. I started going to parties, dating girls and everything else a college kid does.

My parents and I don't really speak all that much now. They found out about what I was doing at school and sort of cut me off. It seems harsh, but there was this one fight, things were said, it got personal. Anyways, now my sister is the only one in my family I really speak to.

My sister moved in, and I thought everything was going great. However, I completely misjudged what living with my sister would be like. The image I had of my sister in my head was a sweet little Christian girl who just graduated from high school and didn't really know what the real world was like.

Apparently, she didn't buy into all the religious stuff like I did growing up. My sister was fucking wild. I took her to a party with me the night she moved in. I thought I was going to have to show her the ropes so to speak. I underestimated her. She held her own. In fact, she was beating me at most of the drinking games we played. It clearly was not her first party.

"Alright," I thought. "My sister is fucking awesome. Living with her is going to be great." I underestimated her again. The next morning I woke up, very hung over. I got a bowl of cereal from the kitchen and sat down to watch TV in the living room.

About a half an hour later, Jenna walked downstairs and crossed right in front of me to go to the kitchen. As she passed by, I saw that she was wearing a small t-shirt and a thong -- that's all. Needless to say, I was a bit shocked by it. Not wanting to make it weird, though, I didn't say anything.

I mean, we did grow up in the same house. We had even seen each other naked before once or twice. But, I had not seen her much since she started to fill out. My sister had a great body. She was fairly tall, only a few inches shorter than me. Her long legs looked so good running all the way up to her big butt and curvy hips. I focused on the pale cheeks of her ass as she bent over to get something out of the fridge. Her ass truly was amazing.

Then my eyes inadvertently made their way up to her chest. Her perky round tits were pressing against her t-shirt, trying to get free. They were pretty large boobs, C cups. Now that I had started thinking about my sister's body, I realized that she had always been an attractive girl. She had long, light-brown hair and a beautiful, angular face with gorgeous green eyes.

As Jenna came over to sit with me in the living room, I realized that I was hard. Naturally, I was mortified that my sister had just given me a boner. So, I just continued to eat my cereal and watch TV until my erection went away. Then I went about the rest of my day as normal. I thought that would be the end of it. I was wrong.

Over the next couple of weeks, I started to get to know my sister. And, I mean I really got to know her. The thong incident was not a one-time thing. She would wear next to nothing all the time. It was as if I wasn't even there. Her ass would be spilling out of her underwear, and she didn't even seem to care if I was in the room. I thought having my own place would be relaxing, but it was hard to relax when my sister was giving me a peep show.

The way she dressed wasn't even the worst of it. The way she acted was even worse. I learned quickly that my sister was very sexually active. Both of our bedrooms made up the whole upstairs. It wasn't the biggest space, and we shared a wall. Sometimes I would be in my room and hear her masturbating over in her room. Sometimes she would bring some guy home and I would be kept up all night by the sound of them fucking next door. It wasn't just awkward moaning either. I could hear them dirty talking to each other, Jenna telling the guy to smack her ass or to give it to her harder.

Once, I came home from a party and walked in on her and some guy fucking in the kitchen. He had her bent over the kitchen table and was giving it to her good and hard. He stopped when he saw me, thinking I might be her boyfriend.

"Who the fuck is this?" he asked Jenna.

"Don't worry, that's just my roommate," Jenna said. Jenna made a pleading face at me. Apparently, she really wanted to fuck this guy. So, I played along, pretending it was no big deal and walked out of the kitchen.

Before I even got to the stairs, I heard them start fucking again. After that, I had a little talk with her, telling her how weird it was having her act like I wasn't there all the time and fucking guys in our kitchen. She told me chill out, but did promise to only have sex with guys in her own room.

In October, I got a job at a bar, working nights. It was nice to have someplace to get away from my sister. Truth be told, she was starting to turn me on on the regular. It wasn't my fault. Anyone would get a chubby looking at my sister in her underwear all the time. But, it was getting bad.

Just a week before I started my job at the bar, Jenna had popped into my head while I was masturbating one night. I couldn't get her out of my head and I ended up finishing while thinking about her. A few days after that, I was jacking off to the sound of her moaning next door. So, my new job was sort of saving me from my own sick thoughts.

The shifts I worked usually ended around two or three in the morning, depending on if I was closing, so I got home late quite a bit. The down side of this was that Jenna saw my time at work as time when the whole apartment was hers alone. More than a few times I came home and found Jenna's dildos in the living room. I guess she would masturbate on the couch and forget to clean up after herself when she went to bed.

It's safe to say that my sister and I had a strained relationship. But, one night changed us more completely than I ever thought possible, eventually creating a sexual dominance competition between us. It was a Saturday night and I had picked up a closing shift. I got home around 3:30 in the morning. It had been a long day and I just wanted to go upstairs and crash into my bed.

When I reached the top of the stairs, I saw that Jenna's bedroom light was on and her door was wide open. I looked inside, and there was Jenna passed out, lying face down on her bed. She was wearing a bra, but her pants were down around her ankles. At first, I thought that she had just come home drunk and passed out while taking off her clothes.

Then I noticed that a big, flesh-colored, rubber dildo was laying on her pillow. Another translucent, pink one was off to the side around her knee. And, the thing that made my dick almost jump out of my pants, a thinner, glass dildo with bumps along it was stuck in my sister's ass.

I couldn't believe what I was seeing. My sister had come home, started fucking herself with her dildos and shoved a glass dildo up her butt. Then she passed out with it still inside her. Even from the doorway, I could smell alcohol on her, so I thought I'd better at least make sure that she was alright. I walked over to her bedside and made sure she was breathing alright. She seemed fine, despite the overwhelming smell of booze coming off of her.

I touched her on the shoulder to see if she would wake up. I figured I could get her to at least get under her covers and maybe take the dildo out of her ass. That would make for an uncomfortable morning I would imagine. And, if she was as drunk as I thought she was, she wouldn't even remember me seeing her like this.

She didn't respond when I shook her shoulder. I shook a little harder. Still nothing. She was passed out hard. I decided I would just do it for her. I reached down to pull out the dildo, but stopped short. First, I thought, maybe I'll take a few pictures.

So, I took out my phone and snapped a few quick photos. I got a few different angles. I mostly focused on her big ass, with the glass dildo sticking up out of it. Then I got some shots from right behind her so I could get her pussy in the frame. Her legs were spread as wide as she could get them since her pants were around her ankles, but I still got a fairly good view of her pussy.

By the looks of things, she must have had a hell of a time fucking herself. There were big globs of her thick cum still oozing out of her pussy and even more plastered along the insides of her thighs. She had made quite a mess of her crotch and ass. Everywhere was covered in Jenna's cum and lube. A lot of it had already started drying and pasting itself to her skin.

Looking at my sister's depraved body, I suddenly noticed that I had unconsciously started to rub a very sizable erection through my pants. Then a very wicked idea came to me. I had planned on just jacking off to the pictures I had taken of her later in my room. But, with Jenna in the state that she was in, why not do it right here where I had the real thing in front of me?

I considered actually fucking her a little, but I quickly dismissed the idea. I didn't think I was capable of actually fucking my sister; while she was passed out nonetheless. I decided I'd better test the deepness of her sleep once again. So, I nudged her thigh. She had great thighs. She had some meat on them, while not looking fat.

Her thigh swayed back and forth a little at my touch, but she stayed passed out. I got a little more daring and actually grabbed her thigh, shaking it back and forth. The wave effect that this produced was incredibly sexy. The waves even made their way up into her ass, jiggling her big ass cheek around the glass dildo. She stayed asleep.

"Well, now or never," I said. I undid my belt and pulled my pants down just enough to get my cock out. Then I started stroking it. I felt so filthy doing it. Here I was with my pants down, stroking my dick to my drunk, passed out sister. My heart was racing at the thought that she might wake up and see me. So, I just decided to cum quickly and get out of there. It didn't take long before I could feel my cum ready to explode out of me.

I put one knee onto the side of my sister's bed and moved my dick close to her, aiming it towards the bottom of her ass. With all the fluids already there, I figured she wouldn't even notice my cum by the time she woke up. Stream after stream of hot cum shot out, landing all over my sister's ass. My orgasm was intense and left me drained.

By the time I finished, I had turned my sister into a cum covered whore. Cum was dripping down her cheeks and clinging to her thighs. A particularly large glob of cum had landed right at the base of the glass dildo and I watched it stream through her deep crack, making its way to her hole.

I pulled my pants up and fixed my belt. I took one last picture of my sister, covered in my cum. Then I finally decided to do what I had come in to do in the first place. I grabbed the glass dildo and started to pull it out. The bumpy dildo made a lot of slurping noises coming out of her lube-coated asshole.

As soon as it popped out of her, my sister's ass involuntarily made a farting sound. Yet another testament to what a filthy whore my sister was. Still, she did not wake up. I tossed the dildo to the side of her bed and put her blanket over her. Then I went into my room and feel asleep as soon as my head hit the pillow.

The next day was Sunday so it was a typical Netflix-watching afternoon. Jenna woke up around noon and staggered downstairs with a crazy hangover. At least she wasn't walking funny from having a dildo stuck in her ass all night. See, I did help. Both of us went about our business as usual. I acted like nothing had happened, and apparently she didn't know anything. That's what I was hoping for. I can't say for sure what she actually remembered doing the night before. Did she remember coming home and passing out while masturbating?

If so, she might think it strange that she woke up without the dildo up her butt. A moment of anxiety washed over me, but I soon dismissed it. Even if she thought it was weird, she would probably just assume that she pushed the dildo out of her ass in the middle of the night. She didn't have any reason to suspect me, did she? All my worry seemed to be for nothing. The day went by fairly normally. A sense of relief washed over me as I fell asleep that night.

The next day was a school day. I had class at 10:00, but Jenna didn't have any classes until 1:00 or so, so I didn't even see her before I left the apartment. I assumed she was still asleep. I walked across campus to my first class. It was in one of the larger buildings that had many classrooms in it, so the halls were pretty packed. My class was on the very bottom level, two floors below the main entrance.

By the time I got to the right floor, I was running a little late. The hallway had practically emptied since everyone's classes had just started. As I was walking past the men's room, somebody grabbed me from behind and pushed me through the door. I stumbled into the bathroom and just barely kept from falling down.

It was an older building still being used from the early half of the last century. The bathroom had an intricate tile floor that had become dirty looking over the years, and the high ceiling had several cracks. I turned around and saw that the person who pushed me in was my sister. She crossed the room, put her hands on me again and practically threw me into a wall, pinning my back against it.

"What's wrong, Matt? You look confused," Jenna said. Before I could answer, she grabbed the athletic shorts I was wearing, along with my underwear, and pulled them down to my ankles. Then she pinned me back to the wall with her left forearm so I couldn't pull them up. I was astonished at how forceful my little sister was. With her right hand, she gently cupped my balls and started fondling them.

"Oh, you perverted big brother of mine," she said. "Do you like my hands on your balls like this?"

"Jenna, what the fuck are you doing?" I said.

"Oh, come on, Matt. Maybe it will help if you grab my big titties." Her teasing, pouty voice was making me feel strange. She was entirely in control of this situation and she knew it. "Hmmm. You're not nearly as hard as you were the other night."

Oh shit. There it was. The explanation. She knew. I don't know how she found out, but somehow she clearly knew what I had done Saturday night. Had she actually woken up? Jenna continued to fondle my balls in her hand and I started to feel myself getting hard.

"There he is. There's our little friend," said Jenna.

I glanced towards the door, suddenly aware that anyone could walk in at any moment. Jenna saw where I was looking.

"Don't worry," she said. "No one will come in... unless you make too much noise."

"Jenna, this is beyond fucked up. Knock it off."

"I don't think so. You see, my big brother has been very naughty. I thought I was safe living with him, but now I see that he's just a sick little pervert, isn't he?" I didn't respond. "Isn't he?!" Jenna squeezed hard on my balls and I suppressed a yelp.

"Now," said Jenna, "I think I need to teach my brother a lesson." By this time, my dick was pretty hard. Jenna let go of my balls and wrapped her hand around my shaft. She started pumping my cock in her hand and waves of strange, awkward pleasure washed over me. She stopped for a second to spit into her hand. Then she resumed jacking me off, lubricating my dick with her spit. It felt amazing and my pleasure was evident on my face.

"Does my big brother like that?" said Jenna. "Does my brother like his little sister jacking him off?" I was torn between the shame I was feeling and the pleasure surging over my body. Jenna increased speed. "Yeah, my brother loves having his big dick stroked by his slutty little sister. He loves getting handjobs in public bathrooms, doesn't he? Any second, someone could walk in and see him with his sister's hand wrapped around his cock." She sped up again.

"Jenna... stop... please... stop," I said. I didn't know how long I would last.

"Oh no, I don't think I will stop. In fact, I think you're going to finish for me." Jenna removed her forearm from across my chest. I didn't even try to get away. She reached down and pulled off her short shorts. She was wearing a pair of pink, cotton panties. Then she did something I never expected. She put her thumb into the waistband in the front of her panties and pushed out, away from her body so I could see right down into her panties. I looked in and saw her pussy, her dark hair shaved short and neat.

She moved towards me and put the head of my penis into her panties, keeping them pulled open and exposed. Then she started jerking my dick hard, forcing the cum out of me. She was going to make me cum into her panties. I had never seen anything like it. I was staring at her pussy and was on the verge of shooting my load.

"Look at me," said Jenna. I looked up and saw that Jenna was staring at me. We made eye contact as she continued pumping away. A very serious look was on her face. "Look at you, you sick fuck," she said. "Your sister is giving you a handjob and you're loving it. You're about to cum aren't you? You're going to cum into your own sister's panties. You're nothing but a sick pervert. Now, cum. Cum into my panties you sick sister fucker."

I started to cum. Both of us looked down as stream after stream shot into Jenna's panties, filling them up. The cloth did a good job of catching the cum and soon a pool was forming in her panties. After five or so streams, my orgasm started to subside. Jenna moved her hips to spread the cum all around. I could see it staining the pink cloth all over, starting in the front and making its way to the back, around the bottom of her ass.

Jenna pulled her panties up tight. I imagined how my cum was now pressing firmly against her pussy and ass. Then she put her short shorts back on.

"See you later, you fucking pervert," she said. She turned her back to me and walked towards the door, leaving me with my dick hanging out. As she walked through the door, I could see a thin, shiny stream of cum dripping down the back of her thigh. And then she was gone.

I just stood there for thirty seconds or so, my back pressed against the dirty wall, my pants around my ankles and my dick hanging out in the open. The initial shock of the situation started to wear off and I pulled my shorts back up and left. I skipped my class and went to the cafeteria. I spent the time I was supposed to be in all my other classes that day sitting at a table, looking at my lunch.

The humiliation I felt was consuming me. I mean, my sister had just jacked me off into her panties. Somehow she knew that I had cum on her ass the other night and now she was tormenting me by treating me like a depraved pervert... and I was. I was a sick pervert who cums for his sister.

After a few hours of sulking and feeling sad for myself, my feelings slowly turned to anger. After I thought about it for a while, I started to think that this was all her fault. If it wasn't for all the shit that she had done, walking around with her ass hanging out, loudly moaning while she masturbated in her room, getting caught being plowed on our kitchen table, then I wouldn't even have been in the state that I was in.

Then a thought crossed my mind. Maybe she had been intentionally teasing me this whole time. It made sense. I mean, she knew that I would see her walking around in her thongs. She had to have known how loud she was when she was cumming in her room. Then I started to suspect that she wanted me to find her in her room on Saturday. Maybe she wanted me to see her like that. Hell, maybe jacking me off into her panties had gotten her hot. Maybe it wasn't just to humiliate me.

I don't like being messed with, so these new thoughts made me very angry. I stayed on campus until 6:30 or so, fuming at what my sister was doing to me. I walked back to the apartment. When I opened the door, I saw my sister sitting on the couch watching TV and having a snack.

"Oh, hey there, pervert," she said to me. And, that did it. I made a decision right there. She needed to be punished. I went upstairs and opened the drawer to my nightstand. I grabbed the bottle of lube I kept there and ran back downstairs. I stood between the TV and my sister, an angry look in my eye. My sister stood up and started to walk towards the kitchen. She looked at what I was holding and said,

"What? Does the perv-boy want another handjob? Can't get enough of your sister, huh?" I walked over to her, grabbed her forcefully by the shoulders and moved her over to the side of the couch. Then I turned her around and bent her over the arm of the couch, her face smashing into the cushions. Her ass was now the highest point of her body and it jiggled as she tried to shuffle away, but I held her down, pushing her face hard into the couch cushion.

"Matt, what the fuck are you doing?" she said, a touch of fear in her voice.

"You've been teasing me ever since you moved in. Almost every day I have to look at you in your skimpy underwear and listen to the sounds of you fucking in your room."

"What? No... no I-"

"I've had it, Jenna. You need to be taught a lesson. One that you're not likely to forget." I grabbed her short shorts by the waistband and pulled them down to her knees. I saw that she was still wearing her pink panties from earlier.

My cum had left a large stain in the bottom of them. That turned me on, actually. I gave her big butt a slap. I liked the way her cheeks shook, so I slapped it again. She wriggled underneath me, trying to get out, but I was able to hold her down.

I pulled down her panties, exposing her pussy and ass. I immediately felt a steamy warmth coming off of her. I grabbed the bottle of lube I had brought down with me and upended it above her ass, spilling a sizeable amount of it down in between her butt cheeks. Then I took my middle finger and worked some of the lube into her asshole. Jenna turned her head to the side and gasped as she realized what I was doing.

"No. No no, Matt please don't," she said. The panic in her voice was clear. I slid my shorts down and saw that my cock was already fully hard from all of this. I worked a little lube around my dick for good measure.

"Call me a sister fucker will you?" I said. "I'll show you a sister fucker." I put the head of my cock up against her puckered, brown asshole and pressed firmly. The head of my cock slipped inside and my sister gave a high pitched squeal. Her butthole suddenly tensed up, squeezing around the head of my dick. I put my hips into it and plowed forward a couple of inches to the sound of a deep, guttural "Unnngh" from Jenna.

"This is going to be a whole lot easier for you if you relax your ass," I said. Jenna's mouth was hanging open and her eyes were closed. She concentrated real hard on relaxing her ass, and soon it was no longer squeezing down on my dick. Relaxed, her ass was still very tight. It was a pleasant surprise, actually. Going in, I wasn't sure whether Jenna would have a tight butthole, or if she would be loose.

I slowly worked my cock in and out of her, forcing her ass to adjust to the size of my cock. My dick was as hard as I had ever seen it. During my slow backstrokes, when most of my dick would come out of Jenna's butt, I could see veins bulging along my shaft. I had only ever had anal sex once before and it was the best sexual experience I had ever had. Now, with the added perverseness that it was my sister's ass I was fucking, my cock was in heaven.

In no time at all, Jenna's ass had adjusted to the size of my dick. Now the fun could really begin. I started humping her ass at a good starting pace. Every thrust of mine drove me deep into her tight butthole. My balls would slap against her pussy and my hips sent a quiver through her big ass cheeks. That was my favorite part, watching her butt shake with each thrust. As I began speeding up, I heard my sister grunting every time my cock buried itself to the hilt.

"Unngh, unnngh, aaaaahuuungh. Matt... please... my ass... UUUUNNNNNGGHHH!" I thrust deep and hard into her, burying my cock deep in her ass. I continued this deep thrusting, my sister's grunts turning me on. After a couple of minutes, I could have sworn I heard her moaning a little in between strokes. Then I started to feel her pushing back into me with her hips.

"Yeah, my little sister loves getting fucked up her big ass, doesn't she?" I said. Jenna didn't respond. She seemed to be in a world all her own. But, it was clear from her face that she was now starting to enjoy the anal pounding I was giving her. "Jenna, Jenna. Look at you, getting fucked up your slutty little butthole. Looks like you're a bigger pervert than I am after all."

I picked up the pace a little. Jenna was now openly moaning. I couldn't believe what a dirty anal whore my sister was. Just the thought of it was getting me hot. Soon, I could feel the cum boiling down in my balls. I was going to blow my load soon and it was going right up Jenna's ass.

"Congratulations, Jenna," I said. "You're going to make me cum twice today. Are you ready?" I didn't wait for an answer. Instead, I started pounding away at her asshole as hard as I could, and thrust my cock in and out at the quickest speed I could muster. Jenna's eyes shot wide open and she let out a long, high pitched shriek as my dick ripped her apart.

Her ass was violently shaking underneath me with each deep thrust. She clutched the side of the couch cushion with her arms and bit down on it to suppress her screaming. Jenna then started making deep, guttural sounds and her eyes became glazed over.

I continued to pound her big ass all the way through my orgasm. My dick spasmed inside her and I shot stream after stream deep into her hole. I gave one last deep thrust into her then slowly pulled my cock out of her ass. As it slid out of her now slick butthole, I saw that her ass was gaping wide open. Without my dick to hold it open, though, it slowly started to close up again.

Finally, I released my hold on my sister and stepped back a couple of paces. She didn't move, remaining very still, her arms had fallen out to the side. She looked so helpless as she rotated her face back into the cushion.

"Let's get a something straight," I said. "You're my bitch." I reached down and pulled my pants up. "Go ahead and keep teasing my like you do. We both know why you do it." I took one last look at my sister, bent over the couch with her ass up in the air. A bit of my cum was now leaking out of her ass. I smiled and went upstairs.

I lay down on my bed and recounted all the events that had happened that day. Quite an amazing turn of events. It was still early, but I was completely worn out. I fell asleep thinking about how I had just made my sister my fuck doll. I imagined different ways I wanted to fuck her in the future. Jenna was mine to do with what I wanted.

But, it seemed I had underestimated her once again. This was the last time I ever did.

I woke up in the middle of the night to Jenna shaking me awake. She was on top of me, straddling my chest. It took a few seconds for me to realize what was going on. The first thing I noticed was that Jenna was wearing an incredibly sexy outfit.

She had on a black corset that looked like it was made out of latex or vinyl. The way it pushed her tits up made them look mouthwatering. She had on expensive looking black, lace underwear, and black, thigh-high boots. I absolutely love thigh high boots. Jenna was looking down at me with a wicked grin on her face. The next thing that I noticed was that I was naked too. Wow, she had even taken my clothes off.

I smiled and said, "Back for some more, huh?"

"I suppose so," she said. Just then, I made my last realization. I was tied to the corners of my bed.

"Kind of kinky, huh?" I said.

"Oh, Matty. You have no idea." Jenna stood up on my bed, took off her panties, and turned around, giving me a full view of her ass. She moved up a ways towards my head and squatted down, her ass about a foot away from my face.

"You were pretty rough on my ass earlier," she said. "Kiss it and make it better." Before I could protest, her ass landed on my face, smothering me underneath it. In a circular motion, she ground her ass onto me. Then she reached back and spread her cheeks, exposing her asshole. She positioned herself so that her asshole was touching my lips.

"Kiss it, Matt."

"What? Kiss your asshole?" I managed to get out from beneath her thick butt cheeks.

"Kiss it like a good brother," said Jenna. I didn't want to do it. I had never put my mouth on a girl's butthole before. That's disgusting. But, I could clearly see that I had little choice. I was tied up and something in Jenna's voice sounded like she meant business. So, timidly, I pushed my lips together and gave Jenna's brown little pucker a small kiss.

"Aaaah, good boy," said Jenna on top of me. "But, that didn't make it feel all better. I think you're going to have to lick it real good for me."

"What?" I protested beneath her. "I can't do that."

"You can and you will. Now, lick my ass or else you'll be punished." She brought her open hand down onto my stomach, slapping it hard. I yelped, but still didn't start licking. Three more times she slapped me before I broke down and stuck my tongue out and lapped at her bitter asshole.

"Mmmmm," moaned Jenna. "That's just what I need. Keep licking it like a good boy." Jenna started rubbing her clit and moaning. After a while, it wasn't so bad. The fact that this was turning her on so much was actually starting to turn me on too. I loved listening to Jenna moan and my dick was starting to respond to it. I continued to lick her ass for about a minute and then Jenna climbed off of my face.

She positioned herself at the bottom of the bed with her head near my crotch. She was staring at my dick and slowly began playing with it a little, running a finger up the length of it then squeezing the tip a bit.

"You know, as long as both of us are getting all of our little perversions out in the open today, I must admit that I've always wanted to know what my brother's cock tasted like," she said. Then she opened her mouth wide and swallowed all of my cock, and I do mean the entirety of it.

Her lips were settled on top of my balls and she held it there for a bit, the tip of my cock a ways down her throat. I had never had someone deepthroat me before. My eyes almost rolled back into my head at the sensation. After about ten seconds, Jenna came up gasping for air. She looked up at me and smiled again.

"See, Matt," she said. "Who says I'm not a loving sister? Do you like it when I take your whole cock like that?"

"Oh my God yes. That feels so good."

"Yeah, do you like it when I do this?" Jenna kept eye contact with me while she lowered her head down onto my cock. She continued looking at me even as she started sucking it, and boy did she suck it. I started moaning from the pleasure of it. But, then she put her teeth lightly against my dick and started slowly grating her way down my shaft. It fucking hurt.

"Ow, what the fuck, Jenna? Ow! Stop it. That fucking hurts." Jenna was still looking up at me and smiled as I cried out, but she continued to use her teeth on my dick for another thirty seconds or so. Then she grabbed me firmly by the shaft and circled the tip with her tongue. Unfortunately, she didn't do that for very long. She stood up off of the bed.

"Let's move on, shall we?" she said. "I'm going to turn you over now. If you try to break free of the ropes while I'm doing this, I'm going to hurt you."

"You already hurt me," I said. "My cock feels like somebody just chewed on it."

"Oh, poor, naïve Matt. That was just a warm-up." I didn't like the way that she said that. My sister was starting to scare me now. What happened to me being the dominant one? Wasn't she supposed to be my bitch now?

It took some time, but she eventually got me turned over. She had to untie one rope at a time and retie it to the opposite post. I thought about trying to break free, but decided against it. I didn't want to find out what she might do to me if I did. Also, there were always three ropes holding me down at all times and the knots were strong. I wondered where she learned to tie such a good knot. Maybe I wasn't the first guy she'd tied up before.

It took a little while, but eventually I was lying face down on my bed, tied to each corner. I couldn't think of any reason that she wanted me on my stomach though.

"I have to get something out of my room. I'll be right back. Don't go anywhere," Jenna said with a little laugh to herself. Yeah, as if I had a choice. She walked out of my room and across the hall, her heels clicking loudly on the floor as she walked. She was only gone for a minute or so, but that was enough to make me worry. What could she possibly be getting? What was I in for?

I heard her heels clicking again, making her way back into my room. The clicking stopped beside my bed. I turned my head to look at her. Instead, I came face to face with a big strap-on dildo that my sister had put on. My eyes went wide and my jaw dropped. Jenna laughed at my reaction.

"Don't worry, bro. I bet you're a natural," Jenna said. The dildo was probably averaged size, but, with it inches from my face, it seemed like a monster. It was realistic looking. It had a natural flesh color and even had veins bulging along it.

Jenna put one hand on the base of the dildo, one hand on the back of my head, and shoved the dildo into my mouth. She wasted no time before fucking my face with her big strap-on. I choked on it at first and she pulled it out.

"Suck my dick, Matt," she ordered, and stuffed it back in. This time, she put both of her hands on the back of my head and pushed me up and down on it. I must have looked ridiculous, but my sister seemed to be loving it.

"That's it, bro. Suck your sister's big cock." She continued to fuck my mouth for two minutes or so, changing speed at irregular intervals. The friction on her pussy was getting her hot. I could smell the aroma of her sex coming from her crotch. She gave me two or three last deep thrusts, which I started to gag on, then took the dildo out of my mouth.

I looked up at her and she smiled wickedly at me. I felt an incredible sense of defeat at that. I thought I was the one dominating my sister, but she was showing me who was really in control. She picked up a big bottle of lube and started to walk to the bottom of the bed.

"Time for your last lesson of the night," she said. Then she started to climb onto the bed, between my legs. I suddenly became very aware of what she intended to do.

"No," I pleaded. "No no. Not that. Jenna don't. Please."

"Please don't what?" said Jenna.

"Please don't," I repeated.

"Please don't what?" said Jenna, and she slapped me hard on my ass. I swallowed hard to help get the words out.

"Please don't... fuck me in the ass." I turned my head to look behind me as best I could. I saw Jenna smiling that same wicked smile.

"Ok," she said. "I won't fuck your ass." All the muscles in my body relaxed a bit. But that didn't last long. "I will, however, plow your ass. I'm going to pound your little asshole, Matt. I'm going to shove it in deep and turn you into a little sissy boy. And, you know what? By the time I finish reaming your little butthole, you're going to cum for me."

Jenna squirted some lube onto her hand and worked it up and down her rubber cock. Then she put a little on my ass and rubbed it all over my asshole. Finally, she took the whole bottle of lube and shoved the nozzle into my ass. Once it was inside, Jenna squeezed, forcing a large amount of lube into my ass.

"You're tense. Don't worry. You're going to love it." Jenna threw the bottle of lube to the side and positioned her hips right above my ass. She lined up her cock and I felt it press against my asshole. "Karma's a bitch, and so am I," said Jenna. Then she thrust forward, shoving a large portion of the strap-on up my ass.

I clenched my teeth and let out a low grunt. The feeling was incredible. It hurt so much. I wished that she had gone in slowly. The feeling of being stretched by that dildo was sending all sorts of pain through my body.

Jenna stayed motionless on top of me for a little bit. At least she was going to let my body adjust now. Slowly but surely she started to work the dildo in and out of my ass. It felt unnatural to me, like I was taking a massive shit, but in reverse. My ass felt so full of my sister's cock.

After a few minutes of very little movement, Jenna started to hump my ass. My ass had started to get used to the dildo and it was moving in and out much easier now. The lube was making slopping noises as Jenna began fucking me proper. Luckily, I was able to relax my ass enough to ease the strain of taking the dick.

Once I was able to do that, the feeling was much different. I still felt completely full, but that didn't seem so bad anymore. In fact, the steady rhythm of Jenna's strap-on moving in and out of me was starting to make me feel good. I closed my eyes and pictured Jenna's hips driving into me right behind me, her ass flexing with each thrust.

I was really starting to enjoy myself now. I lost myself in the sensations that were coming from my ass, and I did something I shouldn't have - I accidently moaned a little. Jenna stopped her steady humping. Then she burst out laughing.

"Oh my God. No. Fucking. Way. Did you just moan?" Jenna began laughing again. My face turned bright red. "I can't believe that. You just moaned while I was fucking you in the ass. I haven't even been fucking you that long. Has your ass already adjusted that much? I guess I was right, you're a natural." Jenna resumed her thrusting, this time going deeper and a little quicker.

"Uuungh," I grunted at the change of pace.

"I can't believe my brother is such a sissy boy. And, here I thought that I was the anal whore. You are loving this, aren't you? Keep moaning. I like that." I kept my mouth shut. "I said, moan." Jenna drove the strap-on as deep as it would go. I was now taking her balls deep. The sudden surprise of the dildo burying itself in my ass so deep forced my mouth open.

"Aaaaaauuuuaaaaggggh."

"That's more like it," said Jenna. Then she changed position slightly, laying down on top of me, using just her hips to pound my ass. Even so, she started fucking me faster and the guttural sounds I was making increased.

"Tell me how much you like this," Jenna said to me. "You like being fucked by your sister's big cock? Tell me. Tell me that you love my cock in your ass."

I obediently obeyed. "I love your big cock in my ass," I said. That seemed to please her and she rewarded me with two hard thrusts before resuming her quick pace on top of me.

"Yeah," she said. "My big brother likes to take it up his ass like a little bitch, doesn't he? You know, you've been such a good little slut. I think you deserve a little reward." Jenna reached underneath me and found my cock. I hadn't even noticed, but I was already semi-erect.

"Ooooh," she said in my ear. "Look at that. Feels like somebody wants to cum." It was true. I did want to cum. I wanted so badly to cum for my sister. Jenna started stroking my dick, giving me a reach around while on top of me, fucking my ass. I was fully hard very quickly. Jenna continued fucking me like this for another five minutes or so. I could hear her breath start to become raspier and I knew that the base of the strap-on was working against her pussy good. She was getting close to cumming and so was I.

Jenna leaned in close to my ear and said, "I'm going to cum soon. But, you have to beg to cum. Say, 'Please, mistress, may I cum?'"

I wasted no time. "Please, mistress, may I cum? Please let me cum. I want to cum so badly, Jenna." Jenna started pumping my cock hard, bringing me almost to the tipping point. But, before I could cum, she let go of my cock and pressed my ass down hard. This smashed my dick between my stomach and the bed. Then she started thrusting deep, each thrust moving my whole body and grinding my cock against my sheets. I was going to cum even without her hand. I looked back at Jenna.

She brought her right hand up to her face and sucked on her middle finger a little. Then she reached around behind herself and shoved her wet finger up her ass. This must have done the trick for her because she started brutally pounding me, writhing like crazy on top of me. My cock started to spasm and I shot a big load onto my sheets and stomach. Jenna continued fucking me hard throughout her orgasm, eventually just grinding her crotch against the base of the dildo.

It was almost 2:00 am and I was tied up, lying in a pool of my own cum with my sister on top of me, her strap-on still buried in my ass, catching her breath. When Jenna finally did manage to move, she slowly slid the big dildo out of my ass and climbed off the bed. As she stood beside me, I saw that the dildo was covered in lube and the wetness of my sister's pussy was leaking out the bottom of her harness.

Casually, Jenna untied one of my arms and started to walk away. Apparently she was leaving the rest to me. When she got to the door, she turned around and faced me. She looked so kinky in her corset with the big strap-on sticking out.

"Matt," she said. "Let's get one thing straight. You're my bitch now." With that, she turned around, walked to her room, and shut the door.It's my own fault really. Maybe I shouldn't have fucked Jenna up the ass like I had. I just couldn't help myself though. And, to be fair, she fucking loved it. That girl is a serious little anal slut.... And, it turns out we have that in common.

A few days ago, my sister and I both sodomized each other. She had pissed me off, so I came home on Monday and shoved my cock up her ass. I had felt so dominant over her. I fell asleep that night dreaming of all the ways I was going to use my sister as my little fuck doll.

However, Jenna had other plans. She tied me up while I was sleeping and dominated me instead. And, I have to admit, she was better at it than I had been. She sat on my face, slapped me around, and eventually fucked my ass with a strap-on. Afterwards, I was shocked at how much I had enjoyed it. As she walked out of my room, she said, "Matt, let's get one thing straight. You're my bitch now."

And, I was. I was her perfect little sex slave. For nearly a week, I did everything that Jenna asked me to do. Jenna was delighted by this, of course. We barely left the apartment for the next few days because Jenna was constantly horny and needed to use me. I obeyed when she told me to eat her pussy. I obeyed when she told me to lick her thigh high boots. I obeyed when she wanted my cock. I obeyed when she told me to lick her ass. She was very fond of making me lick her ass. In fact, it was one of her favorite things to make me do. Sometimes she would have me lick her ass while she was just watching TV or something; just because she was bored.

I thought my sister was over-sexed before, but it turns out I had no idea. She constantly wanted it. And, she was into pretty much everything. Once, she started spanking me, and then ordered me to spank her too. A couple of times, she attached her strap-on to my face and told me to use it to fuck her. And, of course she often used the strap-on to fuck me.

I would never in a million years have let a girl fuck me with a dildo if it wasn't for that night that Jenna tied me up and forced me. She had been so rough, yet I had cum while she was fucking me, and the orgasm I got from that was incredible. It was different and very new to me, but I will admit that I was into it. It unleashed my submissive side. I had always been the dominant one in relationships, but I now had the urge to be submissive as well, and I was good at it.

Yes, I couldn't have been a better sex slave. Of course, that's what I needed Jenna to think. It's true, I actually was enjoying being submissive to her. I still got to fuck her, and I liked that very much. However, I still needed to be dominant sometime. I knew I couldn't be submissive forever. Jenna could be a cruel mistress. She would often bring me to the peak of orgasm and then stop, ordering me not to cum and never finishing me off. She got a thrill out of giving me blue balls. I got back at her by jizzing on her toothbrush and inside her pillowcase. But, that was nothing compared to what I had planned for the weekend.

The idea had suddenly occurred to me on Wednesday. I had been Jenna's bitch for only two days at the time, but already desperately needed to find a way to get back at her. She was actually fucking me with her strap-on in front of an open window when the plan came to me. The first step was to drive out to a stud farm north of town and buy a horse aphrodisiac. They usually use them for stallions, but there is another one specifically for mares. I talked to someone who worked there to find out what would happen if a human were to take some. The way he described it was a sexual frenzy.

Apparently, the stuff was so strong that, if humans took it, they literally wouldn't be able to control themselves. This was going to be very useful to me. I bribed the man into giving me some. The second step of the plan was to talk to a frat boy. Normally, I hate frat boys, but it seemed I needed them for this.

There was a frat boy named Eric that my sister and I both knew. I explained my plan to him (not telling him Jenna was my sister, of course). In the end, there was little risk to him, and he got something good in return. All he had to do was invite Jenna and me to a party on Saturday. He invited us to the party at his fraternity, and Jenna said she would go. Perfect, now I just needed a little cunning to pull off the rest of the plan.

Saturday was business as usual. I woke up and went downstairs. Jenna was completely naked, watching TV on the living room couch. She only really wore clothes when she felt like it at this point. She called me over, spread her legs, and had me eat her pussy until she came. Then I had breakfast and went back upstairs. Typical morning for that week, actually.

Around 2:00 pm, Jenna walked into my room wearing her dominatrix outfit with her hair pulled back. She had the thigh high boots, the corset and, of course, the strap-on. I didn't even hesitate. I obediently took off my pants and got down on all fours. Jenna mounted me and started pounding me in the ass.

I had learned that her strap-on was double sided. There was a portion of the dildo that went inside of her as well. I guess that's why she loved using it so much. Jenna was in high spirits as she humped the rubber cock into my ass. It was filling me up so much that it hurt. Jenna was being really rough on my ass, stretching me out and slapping me. She was mocking me, trying to humiliate me even more.

"What's the matter, Matt? Forgot how to take a cock? Does my little fuck boy need a rest?" She continued to peg my ass for another ten minutes or so. I didn't get to cum, but that was alright. Just meant more satisfaction later, during the evening I had planned.

At 9:00, we both started getting ready for the party. Around 10:00, we were both ready to go. Jenna was wearing a sexy, tight dress that was sort of silver colored. It was very short, barely covering her ass. We were almost out the door, when Jenna suddenly decided to pull it up to her waist and shove my face in between her big cheeks. I pulled down the black thong she was wearing and licked her ass at her command while she rubbed her clit. 'Enjoy your dominance while it lasts, Jenna,' I thought to myself.

It was only a ten minute walk to the frat house. I had only ever been to a couple of frat parties, but I knew what to expect. We had to go around back and were let into the basement, which was the main party area. There was a bar set up, drinking games in every corner with a large beer pong table in the middle, a dance floor, blaring music and several couches along the walls. The place was packed. Jenna told me to go get her a drink while she went and mingled. I made my way to the bar.

Along the way, I saw Eric across the room. He had seen me come in and nodded to me. Good. Everything must be set. I got myself a beer and a vodka and cranberry for Jenna. The horse aphrodisiac I had gotten came in pill form, so I had crushed a half of one up earlier and put it in a small container. The man I bought it from said a whole one might be a little too dangerous. I stealthily added the crushed up aphrodisiac to Jenna's drink and delivered it to her. It was supposed to take at least an hour to start taking full effect, so I had some time to kill.

Jenna went off on her own to mingle and I decided to do that as well. Many of the frat boys were giving me strange looks. 'Those ones must be my recruits,' I thought. I talked to a few people, but never for too long. I really tried to find someone to get along with at this party, but it was tough. Drunken frat boys and sorority girls are generally pretty uninteresting people.

After 45 minutes or so of trying, I gave up and took a seat in a recliner in the corner. I was only sitting for about five minutes before Jenna came over and sat on my lap. We tell everyone we meet that we're roommates, so no one was weirded out by this.

"I fucking hate frat boys," said Jenna.

"Sweet. I knew we had something in common," I said. "I mean... that and the abnormal sex drives."

"Ha ha," laughed Jenna. "Yeah, it's like we're related or something." Jenna's tone was warm. It was nice. She had been so hard on me all week. It was nice to talk to her like this for a change, like we used to talk. I started to regret this plan, wondering if it wasn't the best thing to do. Just then, Jenna leaned in and whispered in my ear, "Let's go home. I'm going to fuck the shit out of you." She bit my ear. "Your ass is mine, Matt." And, just like that, the regret was gone. My plan was the only way.

"How about we stay a little while," I said. "We can at least get drunk before we leave. Open bar."

"Ok, but people tell me I'm a mean drunk," Jenna teased and smiled. I got us both another drink and returned to the recliner, Jenna returning to my lap.

Halfway through her drink, she started grinding her ass on top of my dick, slowly picking up speed. Was the aphrodisiac starting to take effect? Oh shit! I hoped that alcohol wouldn't mess with it.

"Let's dance," said Jenna, quickly grabbing my arm and dragged me out onto the dance floor. It was packed full of sweaty college kids dry humping each other. We put our arms around each other and Jenna started grinding hard. She was quickly straddling one of my legs and moving her crotch up and down my thigh. Her tits were rubbing against me. They were so soft and nice. But, not as nice as her big ass, which I was squeezing with my left hand.

One song ended and another one began. Jenna turned around, grinding her ass into my crotch and I put my hands on her hips. Jenna was really getting into it. I loved it when she would bend all the way over at the waist and just shake her ass side to side. I was getting hard from all the friction.

Near the end of the song, Jenna grabbed my hand and worked it up under her short dress. The dance floor was dark and crowded so no one even noticed. I started to feel her pussy through her panties when I realized that she was wet. No. More than wet. She was drenched. Her panties were completely soaked through. I had never seen a girl that wet. She may have even been dripping through her panties.

Jenna turned her face towards me and I saw the look of wanton pleasure on her face as my hand moved across her pussy. Her expression was that of pure lust, completely uninhibited by the fact that people were all around us. The aphrodisiac had certainly started to work. Jenna was breathing heavily and her voice was strained as she said,

"I need you right fucking now." She started to reach her hand into my pants, but I grabbed it and guided it away. I stopped feeling her up and straightened her dress. If what the guy at the stud farm had told me was true, Jenna wouldn't even be able to control herself soon. I needed to get her away from the party before she tried to fuck me right there on the dance floor. I took her hand and walked with her upstairs through the house.

"Where are we going?" asked Jenna.

"I believe you said you needed me right now. Sooooo, I'm finding a place."

"Ha. I don't think we're supposed to be up here." Jenna giggled.

"Don't worry about it. I've been here before. There's a room over this way that no one ever uses."

"Fuck it. Let's just do it right here, up against this wall," said Jenna and made a grab at my belt buckle.

"Patience, Jenna. Patience."

"This is strange. I've never been this horny in my life. I feel like my pussy is on fire." I smiled to myself. This was working out perfectly. "Matt, I need cock. I need it so bad. Right now." Actually, this was working out even better than I imagined. Jenna's libido was controlling her now. She seemed drunk with lust.

We walked down a long hallway and I opened the door to a big room that looked nearly empty. I closed the door and it became pitch black. As soon as the door closed, Jenna was on me, kissing me on the neck and grabbing me. She quickly got her hand down my pants and was fondling my balls.

I hit a switch on the wall, and a single light in the center of the room turned on, creating a large circle of light on the floor. At the edge of the light, thirteen or so people were standing, partially hidden by shadow.

"Wha... What?" said Jenna. To everyone else, she might have seemed a little drunk. None of them knew about the aphrodisiac now coursing through her body. That was good. I wanted everyone to see her only as a dirty slut and nothing else.

I gently grabbed Jenna by the hand and led her into the middle of the room. Directly beneath the single light, there was a mattress on the floor covered with sex toys. Next to that, there was a wooden stockade -- one of those things that they put prisoners in a long fucking time ago. You put your head and hands through and it locks you in. It stood at the perfect height for Jenna. I had only told Eric to get a mattress. The stockade and toys must have been his ideas. I also noticed a man holding a video camera. Another good idea from Eric. I made a mental note to buy him a beer later.

"Hello, everyone," I said. "The guest of honor has arrived." I gestured to Jenna and everyone cheered. A few guys whistled at her. There were a few cat calls, a couple of which came from girls.

"What's going on," Jenna said.

"Jenna, this is your surprise gangbang." Jenna's eyes went wide and she took a few steps backwards towards the door. I put my arm around her shoulder and guided her back. "She may seem modest now," I laughed, "but this little slut will beg you for it once the clothes come off. Won't you?" I said to Jenna. She stared directly into my eyes and I knew I was right. She literally couldn't resist herself now. The drug was overcoming her own will, morphing it into deep, carnal desires. All she cared about right now was getting fucked.

I unzipped her dress and slipped it off of her. She didn't even resist. The frat boys resumed their cheering and cat calling. Jenna was standing in the middle of the room wearing only a matching black bra and thong with her high heels. The heels could stay on. The rest couldn't. I unhooked her bra and freed her C cups. All eyes devoured the sight of her round tits. She covered them halfheartedly with her arms.

Next, I grabbed the waistband of her thong. I gently kissed one exposed butt cheek before I slid down her panties, stretching them over her big ass. They were sopping wet and landed with a smack onto the wooden floor when I tossed them aside. Just like that, I was looking at my own sister completely exposed in front of a group of incredibly horny college students.

There were nine guys and four girls by my count. I had had Eric choose who would come. They mostly seemed to be members of his fraternity, the girls were from their sister sorority. They all were holding drinks and appeared to be thoroughly amused. Several of the guys had already started rubbing themselves as they stared at Jenna. She looked amazing. Most of the girls in the crowd were more reserved. However, I noticed one girl that seemed quite drunk with her hand shoved down the front of her jeans.

I brought Jenna over to the stockade. She bent over, placing her neck and wrists on the wooden board. I placed the top down and locked her in with a metal latch on the side. She was bent over at just under a ninety degree angle, her ass sticking out, completely exposed. I walked behind her to admire the view. She was so vulnerable like this. And, she couldn't help herself -- she desperately wanted it. No, she needed it. That's why she wouldn't resist. She actually needed to be fucked. I couldn't even imagine how her body must have been feeling under the influence of the aphrodisiac.

Now that she was in position, everyone became much quieter. They were all waiting for me to start things off. I walked up behind her and filled my hands with her big ass, caressing my way down her thick thighs. I could smell the scent of her pussy, thick in the air. The intoxicating aroma filled my nostrils and I looked down at her dripping pussy.

Then I spanked her hard on the ass. She let out a surprised gasp followed by a moan. I spanked her again, watching her cheeks jiggle. She moaned again. I spanked her three more times, savoring the feeling of my hand pressing hard into her soft flesh. She couldn't take any more.

"Oh, god! Please fuck me! I need a cock right now!" she screamed.

"Holy shit, this girl really is a slut," I heard one of the girls say.

"You heard her," a guy's voice said, "get to it!" I quickly undressed and threw my clothes away against a wall. Then I grabbed a bottle of lube from off of the mattress. I positioned myself behind Jenna and put some lube in my hand. I began to stroke myself, spreading the lube over my cock. I was already fairly hard from all of the buildup and I was soon fully erect.

"You know, this little slut has an insatiable pussy," I said to everyone. "However, I happen to know that she prefers it up the ass." There. That little lie would make sure no one had any reservations about fucking her ass. I pressed my cock firmly against Jenna's asshole and quickly slid in. Jenna squealed a little as my cock split her cheeks but she was soon moaning crudely. I grabbed onto her hips and slowly pushed my way inside. It didn't take very long for her to become accustomed to the size and I started fucking her.

It was such a rush nailing her in front of all of those people. If only they had known that they were watching me fuck my own sister up her ass. I slapped her butt hard and started thrusting into her deeply. The drug flowing through her body must have dulled a lot of the pain to allow me to fuck her like this so soon after initially penetrating her.

"Uuuungh, uuuunggh, uuuunnnnnnnnggggggghhhh," grunted Jenna each time I buried my cock deep in her butthole. Her body moved forward a little with each hard thrust, but the stockade kept her in place. Her breathing was loud and she moaned without shame. Many of the guys had already taken off their clothes and were stroking themselves to get hard. Bondage seemed to suit Jenna well. She looked damn hot taking it up the butt like this.

"Oh gawd. Fuck me. Fuck me. Fuck me," said Jenna. Waves of pleasure were washing over her, sending her deeper into her own world of desire. I imagined what would happen once someone actually started fucking her pussy. That wasn't going to happen for a while though. I had made a point of telling everyone how much she liked it in the ass, and what man in their right mind would pass up the chance at anal sex with a girl like Jenna? Her ass was top notch -- big, round and juicy. The feel of it was incredible around my cock.

"Give me that dick!" screamed Jenna. "More. More. Give it to me!" At that, one of the guys in the crowd walked out towards us, fully erect. He made his way to the front of Jenna and guided his cock towards her. He grabbed Jenna by the hair and rubbed his cock all over her face, slapping it against her cheeks a couple of times. Then he stuck it in her mouth.

Jenna greedily sucked at the guy's cock. I could hear her slurping loudly as she took it from both ends. The reaction on the guy's face was immediate. His jaw fell open and he raised his eyebrows high. Jenna was trying to suck the cum right out of him. He pushed himself deeper into her mouth.

"Yeah, bitch. Suck that cock," he said. "Suck it nice and hard." He started thrusting back and forth, fucking Jenna's face. Jenna continued to slurp at it. She had an intense hunger that could only be satisfied by cock.

All of the frat boys were now standing around without clothes and stroking their hard dicks. There would be no lack of meat for Jenna tonight. The girls in the crowd all seemed to be getting turned on as well. One was fondling her breasts over her shirt and one was rubbing her clit through a pair of tight pants. There was another girl who was topless and stroking the cock of the guy standing next to her. And, the girl that had been playing with herself earlier was now standing in only her bra and panties and had started fingering herself furiously.

I watched her for a little bit, giving it to Jenna hard. Soon, I gasped as I began to cum. I gave one last thrust and shot my load deep inside her ass. Jenna moaned around the cock that was filling her mouth, the warm cum flowing deep inside her asshole. As my orgasm subsided, I spread her ass cheeks and pulled out my dick. Her ass continued to gape open a little. I stepped back and made room for another. Everyone was ready to step up and Jenna's ass was quickly filled with another cock.

The guy holding the camera moved in for a close-up on her face. The frat boy face fucking her looked like he was going to cum soon. The cameraman framed up Jenna's face as the cock slid in and out of her mouth, a little saliva running down her chin.

"Holy shit, I'm going to cum," said the frat boy. He shoved his cock deep, his balls pressing up against Jenna's lips. Her eyes shot open in surprise as the cock invaded the back of her throat and held there. Jenna started to gag a little as the cum began to shoot down her throat, but she managed to swallow it all down. The frat boy pulled out, his entire shaft slick with Jenna's saliva, and Jenna coughed and gasped for air. The cameraman put the lens right next to her face.

"Tell the camera what your name is," he said.

".... My name... is Jenna... and I'm... getting gangbanged," she managed between gasps of air. Her body was rocking with each thrust of the frat boy fucking her ass. "I just swallowed a load of cum... and there's a cock deep in my ass." She had barely finished her sentence before her mouth was filled with another frat boy's cock.

The cameraman circled behind her to get a close up of her ass getting fucked. Her ass jiggled violently as the guy fucking her slammed into her. Her butthole was slick and his dick was meeting little resistance. Jenna's pussy was flowing with juices and they were dripping off of her. I saw a puddle had formed between her legs on the floor and more was streaming down her thighs, reminiscent of the time she had jacked me off into her panties and some of it had leaked out.

Jenna's legs were spread as wide as she could get them under the circumstances and her knees were bent slightly. Holy shit, she was actually pushing back against the dick thrusting hard into her. Her craving for cock was intense. I suddenly wondered what her craving for pussy was like.

I walked over to the girl who was fingering herself and asked if she had ever been eaten out by a girl. Everyone saw where I was going with this and several guys cheered the idea. I guided her over to the other girl who I had seen rubbing her clit through her pants.

"It seems that you two have the next turn," I said.

"Fuck yeah! Get some, Melanie!" yelled one of the frat boys. The girl that had been rubbing her clit, Melanie, blushed but didn't say no. I waited until both of the guys fucking Jenna came. Jenna swallowed yet another load and her ass was filled with more cum. Both guys moved back into the crowd and I walked the two girls over to Jenna.

I didn't know if Jenna was even into girls. Even if she wasn't though, I was sure the drug would persuade her. Both girls stripped down naked. I guided Kelsey, the one who was fingering herself earlier, towards Jenna's face.

"You ready to eat this pussy?" I asked Jenna. She didn't say anything. She just opened her mouth and stuck out her tongue. Kelsey swung one leg up over the stockade and pushed her hips forward until her pussy was pressing against Jenna's mouth. Jenna began lapping at it with her tongue. Kelsey pressed harder against Jenna until her face was buried in her cunt. Jenna passionately kissed Kelsey's crotch, eating it with vigor.

Meanwhile, Melanie had made her way behind Jenna. She knelt down directly behind her, placed a hand on the side of each of Jenna's fat cheeks and shoved her face into her pussy. I could hear Jenna's muffled screams of joy coming from Kelsey's cunt. The three girls had formed a train of pussy eating and each looked like they would need to cum soon.

Melanie rubbed her clit quickly as Jenna's pussy juice flooded into her mouth. I watched closely as she spanked my sister's ass hard and worked her tongue deep into her hole, then licked her clit delicately. Jenna was the first to cum. Finally having a tongue to eat her out after so much stimulation was too much for her. Her orgasm was an eruption as her entire body shook and she squealed loudly. Melanie stopped licking and picked up a strap-on from the mattress.

Kelsey was about to cum. I could see it on her face. But, she suddenly moved her pussy away from Jenna's mouth. She took her leg off of the stockade and put it back on the ground. Then she turned around and stuck out her ass towards Jenna's face. She grabbed Jenna by the back of her head and roughly shoved her face into her ass crack. Luckily, Kelsey was wearing very high heels so Jenna's mouth was pressed directly against her asshole.

This surprised me actually. I could not think of a better thing for Kelsey to have done. After all of the times I had eaten Jenna's ass, I was finally watching her forced to lick another girl's asshole. Kelsey was moaning loudly with two of her own fingers shoved deep inside her pussy. Just then, Melanie finished putting on the strap-on and moved behind Jenna again.

Melanie had another smaller dildo in her hand which she shoved into Jenna's ass. Then she positioned the strap-on at the entrance to Jenna's pussy and roughly thrust in. Jenna was so wet that the dildo was immediately buried to the hilt. Melanie wasted no time in getting started and quickly began pounding Jenna's cunt. Melanie and Kelsey were talking dirty to Jenna.

"Eat my ass, bitch," said Kelsey. "Shove your tongue in there deep."

"Yeah, take it you whore," said Melanie as she picked up her pace. "Does it feel good in your pussy? Enjoy it while it lasts because, after I'm done, all these boys are going to fuck you in your fat ass."

Melanie began fucking Jenna hard. Jenna screamed with delight into Kelsey's asshole which seemed to send a wave of pleasure through Kelsey's body and she started cumming. Jenna came moments later. Finally having something inside her pussy had sent her head spinning very quickly. Kelsey's orgasm finished and she shakily walked back to her spot in the crowd on wobbly knees.

Melanie continued pounding away at Jenna's pussy, the smaller dildo still firmly lodged in Jenna's ass. She was being double penetrated by sex toys. Melanie was enjoying the friction of the strap-on and looked like she was going to cum soon as well. She stopped fucking Jenna and pulled out of her. Then she slipped out of the harness and pulled the dildo out of Jenna's ass.

Melanie walked around to Jenna's face and shoved the dildo into her open mouth. Jenna's lips closed around it and Melanie let go, leaving the dildo hanging out of Jenna's mouth. Then Melanie positioned herself directly in front of Jenna's face. I thought she was going to make her eat her out, but she didn't. Melanie spread her legs a little and bent her knees, still standing. Then she shoved two fingers up her cunt and started fucking herself ravenously. Her fingers were sloshing in and out of her soaking wet cunt, the sound loud enough to reach the back of the room.

Suddenly, Melanie put one leg up over the stockade as Kelsey had done earlier. She continued to shove her fingers in and out of herself quickly. Then Melanie began to scream as her orgasm took hold of her and she squirted all over Jenna's face. Several people cheered at this. Jenna opened her mouth, trying to swallow as much of it as possible. Holy shit, sorority girls are fucking crazy.

Melanie soon took her place back in the crowd and three more frat boys started fucking Jenna; one inside Jenna's mouth, another in her ass, and one more who was just jacking off. Jenna stopped sucking the other guy's dick when the one jacking off was getting close so she could eat his cum.

The night continued like this for a long time. There was always someone fucking Jenna. Sometimes it was only one guy. Other times it was three guys. Then they would cum and someone else would jump in. Everyone took advantage of fucking her big ass. It became a sort of game to see how much cum we could actually fit inside Jenna's ass. Everyone shot their load as deep as they could up her butt so it wouldn't leak out. I couldn't even tell you how many loads were inside of her.

Just about everyone fucked her multiple times. They would fuck her once, watch for a while, and then fuck her again once they had rested enough. I myself fucked her three times -- once in the ass, then in her mouth, then once more in her ass.

Jenna continued to beg for more throughout the entire thing. She was completely insatiable. Granted, most of the guys were fucking her in the ass, but every once in a while a girl would jump in and eat her out. The last time I fucked her in the ass, Kelsey was just underneath me eating her pussy. I loved watching Jenna cum while my dick was shoved up her butt.

There was only one instance when I thought Jenna was going to finally break. There was a big, black guy named Michael with a massive, fat cock. He fucked Jenna's ass hard and there were tears running down her face. She was screaming as his cock stretched her hole to its limit, but she kept begging for more. She needed it inside her. Since she kept asking for more, Michael gave it to her. He was so rough with her. The stockade was shaking under the power of his thrusts.

Before Michael came, he pulled his tree trunk of a cock out of her used ass and had Jenna suck it. He filled her mouth with his cock, making her taste her own ass and gagging her. Her lips had to stretch wide open to fit around it, and when he came, Jenna couldn't handle the amount of semen filling her mouth and a lot of it spilled out and down her chin.

We didn't keep her in the stocks all night. Eventually, we took her out and moved her over to the mattress. This made for some very interesting positions. Jenna would sit on a cock, shoving it up her ass and spread her legs wide for another guy to fuck her pussy while taking yet another cock into her mouth. Sometimes she would suck someone's dick and jack off two people on either side of her with her hands.

One of my favorite positions involved the girl who was stroking the guy standing next to her earlier. Her name was Claire and apparently the guy she was jacking off was her boyfriend, Brad. The two of them fucked Jenna together. Claire lay down on the mattress and had her eat her pussy while Brad fucked Jenna from behind. Brad was really rough on Jenna too, pulling her hair and riding her hard.

Jenna was fucked for a few hours. Her body was constantly being shaken as everyone violated her holes. She took load after load of cum, never in her pussy, but everywhere else was fair game. Her stomach must have been full to bursting, but that was nothing compared to how much cum we pumped into her ass. I don't know how many loads she took in the butt, but it was definitely the hole of choice. By the end of the night, her ass was gaping open and some of the cum had started to leak out.

Around 1:30, everyone was exhausted. The cameraman got one final shot of Jenna lying motionless on her stomach, cum dripping out of her butthole. Everyone slowly got their clothes on and started to leave. Jenna continued to lie on the mattress, everyone getting one last look at her used body before they left. One of the girls gave her big booty one last slap before walking out the door.

Eric was the last of the frat boys to leave. He nodded his head towards me and shut the door behind him. The gangbang was over. Time to get Jenna home. She was in a sexed up stupor as I put her clothes back on her. It was sort of like taking care of a drunk at the end of the night. I zipped up her dress and walked her back to our apartment. The whole way there, Jenna had to lean on me to stay upright. It seemed that she had had her coordination fucked right out of her.

About a block away from our place, Jenna started rubbing her hands all over me. Holy shit, the aphrodisiac was still affecting her. She was weak, but still needed more. I opened our apartment door and took Jenna up to her room, lying her down on the bed. She tried to pull me down with her, but there was something I needed from the kitchen. I left Jenna on her bed, rubbing herself through her ruined panties.

Moments later, I returned with a drinking glass. I helped Jenna back out of her dress and tossed it aside. Then I took off her bra, taking a minute or two to play with her luscious tits. Then I had her stand up and turn around for me. Her thong was doing little to conceal her gaping asshole. Some cum had leaked out while we were walking home and was slowly making its way down her crack.

"Look, you've gone and ruined your pretty thong, Jenna," I said. I slid down her panties and wadded them up into a small ball. "Open your mouth." Jenna did as she was told and I stuffed her dirty panties into her mouth.

"Good," I said. "Now, squat down." Jenna squatted down. This made her ass look even better. I made a mental note to fuck her reverse cowgirl one day. "Spread your cheeks apart." Jenna reached back and spread her cheeks, exposing her gaping hole. I placed the glass I had gotten underneath her asshole.

"Good girl. Now, push out that cum. Push it all out." Jenna started pushing. It took a few seconds, but then the cum started sputtering out of her asshole. "That's a good girl. You're going to make yourself a nice cum fart cocktail." Jenna continued to push, the cum now coming out in waves. It was a tall glass, but it was soon about half full. That's a lot of cum to have in your ass.

Eventually, Jenna couldn't push out any more. I was sure there was more in there, but it would just have to stay in there for now. I wiped the excess cum off of her ass using Jenna's bed sheets. Then Jenna sat on the edge of the bed and I handed her the glass, telling her to drink it. Jenna began chugging the cum in big gulps. The thick liquid that had just come out of her ass slid down her throat, filling up her stomach.

"How do you like your new diet?" I asked her. Jenna finished and set down the glass. Cum was all over her lips. She licked it off and opened her mouth to show me that she had finished. I noticed that Jenna's hand was back working on her pussy. Her face was pouty as she looked up at me, begging me for one more go. I smiled down at her and started taking off my clothes. I positioned Jenna on the bed, lying face down in a prone position with her legs spread.

One more fuck before the night ended. I crawled on top of her and rubbed my cock between her soft buttcheeks until I got hard. Then I slowly worked my way inside her pussy. She was still incredibly wet and I slid in easily. Jenna began moaning loudly as I started fucking her. I didn't think I was going to last very long this time, so I was going to make it count.

I grabbed onto her arms and pushed them down onto the bed, pinning her down. Then I started roughly fucking her, slapping against her thighs and ass, filling the room with the sound of our bodies colliding. If any of my neighbors were awake, they surely heard it. Jenna screamed underneath me, her orgasm rising. Her body shook underneath me as I shoved my cock into her hard, ravaging her.

"I'm... I'm... I'M CUMMING," Jenna yelled. I felt the walls of her pussy tighten around my cock and there was pressure pushing me out. I pulled out my cock as Jenna squirted. A flood of pussy juice shot out of her with incredible force, soaking her sheets. I started pumping my cock as I watched Jenna's orgasm take control of her, sending electrical pulses of pleasure through her body. Her legs shook, making her thighs and ass wobble back and forth. I almost came just watching her.

I waited for her to finish cumming then rammed myself back into her pussy. It only took a few more strokes and I shot my load deep inside her. At that moment, I had broken the ultimate taboo. I came hard just thinking about how I was filling my sister's pussy with my hot cum. I lay on top of her for a while as my dick slowly became soft inside of her. Eventually, I climbed off and started putting my clothes back on.

"More," whimpered Jenna. "I need more." I couldn't believe it. The horse aphrodisiac was still in control of her. But, there was nothing I could do. I was completely spent and I wanted to go pass out.

Jenna reached behind her and shoved a finger into her ass, using her own pussy juice for lube. This quickly became two fingers... then three. In no time, Jenna was trying to work all five of her fingers into her ass and was making steady progress. She was all the way up to her last knuckles and pushing hard, trying to shove her entire fist into her ass. She grunted and clenched her teeth as she tried to force it in. It looked painful. Then her asshole stretched wide over her knuckles and she was fisting herself.

"Oooooooh! Oh gawd. Oh my gawd. Yes!" Jenna screamed and started fucking her ass with her fist. I was in awe. Her entire hand was inside her ass and her hole was clenched tightly around her wrist. There was no way her fist would have fit in if she hadn't had her asshole stretched all night. Even then, she probably couldn't have done it had the horse aphrodisiac not given her the drive to do it.

Jenna was fingering her pussy as well and I watched until she came. She was lying on the bed, exhausted, but she still wasn't finished, working her fist in and out of her ass. It looked like she needed to just fuck herself to sleep. So, I opened up the trunk where she kept all of her sex toys and threw some on the bed with her.

I left her in her room to fuck and suck her toys until she passed out. I went into my room and feel asleep quickly. I had learned my lesson, though, and locked my door behind me.

The next morning, I woke up around 9:00. I went downstairs, had a bowl of cereal and started watching some Netflix. Around 11:00, Jenna woke up and staggered downstairs. The effects of the horse aphrodisiac had finally worn off. She had put on a bra and panties and was walking a little bow legged. She was obviously very sore from the previous night. She walked past me, glaring all the way to the kitchen. She came back into the living room with some toast and a large glass of water.

"Is that your cure for a sex hangover?" I asked her. She just glared at me some more. But, she did sit down on the couch with me. We watched TV together for a while. Jenna didn't say anything. After some time, she started to shift uncomfortably in her seat. She finally broke down and talked to me.

"My ass hurts really bad," she said pitifully.

"Well, maybe you shouldn't have shoved your fist up there," I said.

"Well, maybe you shouldn't have drugged and gangbanged me!" Jenna said, angrily. But, then she whimpered at her sore ass.

"Take off your pants and lay down on the floor," I said.

"What? No. Fuck you."

"Relax, I'm going to help you. Now, lay down." I went into the bathroom and Jenna reluctantly took off her panties and lay face down on the living room floor. I returned with a tube of cream. It had something in it to relax muscles. I straddled Jenna's legs and sat down on the back of her thighs. Then I started massaging her big ass. I could see the remnants of dried up cum and pussy juice coating the inside of her thighs and in between her ass cheeks. I put some of the cream on my hands and worked it all over her big cheeks. Then I spread them apart and smeared some into her crack, working it all around, making sure to coat her asshole.

Jenna continued to whimper, but eventually the cream worked its way into her and began soothing her ass. I kept moving my hands over her ass, kneading her fat butt with my hands long after the cream was rubbed in. Jenna began to relax even more beneath me and I heard her breathing getting heavy. I leaned down, putting my face next to hers and kissed her hard on the lips. She returned the kiss. She rolled over and our bodies quickly intertwined, locked at the lips as we continued to kiss passionately. Our hands roamed freely, exploring each other's body like it was the first time.
