The story starts off the night before this happened...

​

I went to a different school than my girlfriend Haley, but I was in town for the weekend visiting. Haley was a dark, busty brunette. We had been dating for a couple years and regularly visited each other during the school year. I'd never met her dorm mate before, but from what she would tell me I knew that they didn't get along at all. Haley would regularly complain about her and was hoping to switch to another dorm room before the school year ended.

​

I made the drive out to her school for the weekend on Thursday, and we didn't have much planned aside from going to a house party with some of her friends that night. The drive took longer than I expected and by the time I parked on campus, Haley was ready to head to the party.

​

We had a good time at the party and got pretty drunk. Her friend gave us a ride back to the dorm building after and as we were walking down the dorm hall, Haley warned me to be extra quiet when we went inside so that we didn't wake up her roommate and piss her off. We unlocked the door and walked into the pitch black dorm and got in bed as quietly as we could.

​

The bed was fucking tiny. It was the first time I had visited her in this dorm and I just remember how small that bed was. There was no option to sleep next to each other. I laid on my back with half her body on top of me, her head resting on my chest. It wasn't long before I felt her hand gently glide down my body to my crotch, and her tongue lick the side of my neck. I reached down with one hand and grabbed her ass a bit as her grip on my shaft over my briefs tightened.

​

"We have to be really fucking quiet," Haley whispered in my ear.

​

I knew this was probably a bad idea, but I'm a guy and I wasn't going to stop her. Her roommate was about four feet away at a maximum, asleep. Haley pulled my briefs down just enough for my cock to spring out and took off her panties. She climbed on top of me, held the base of my cock, and sat down slowly. My cock slipped into her pussy and she sucked on my neck as her groin touched mine, fully inside her.

​

She rocked her hips back and forth, and I put both hands on her ass as she controlled the rhythm, bouncing on my cock. I let out a slight moan and she immediately clamped her hand over my mouth.

​

"Shut up," She whispered in my ear, "I want you to cum inside me."

​

She increased the speed and I felt her hot breath in my ear. I gripped her ass harder, pulling her down on me as she writhed her hips under my tight grip. I felt my orgasm start to build and I pulled as hard as I could on her perfect ass.

​

"Fuck yes daddy, are you going to cum for me?" She whispered in between the heavy breaths she was trying to muffle.

​

I came almost instantly from hearing that. My body went rigid as I pulled her hard against me, feeling my cock erupt inside of her as she milked my cock with her pussy. I pushed my cock in as deep as I could as I felt every drop of cum that I had shoot into her. She kissed me on the cheek and giggled, sliding off of me. We passed out right after.

​

Next thing I knew, I woke up to her phone alarm going off. Haley got out of bed and started getting ready for class and I fell back asleep. I'm not sure how much time passed, but I woke up again to the sound of her roommate getting up.

​

Shit. I hadn't given any thought to what we did last night and was pretty worried that her roommate heard us. Luckily I was laying on my side facing the wall, so I just pretended like I was still asleep as I heard her moving around behind me. I'd never met her roomie, and I didn't even know her name. I turned my head slowly to look behind me to see what she was doing.

​

The first thing I saw was a giant ass in a black g-string. She was wearing a white t-shirt, and her black hair ran down the back of it to the tiny waist perched above her enormous ass. I thought to myself it was a good thing that she was facing the other way, until I realized she was getting ready for the day and looking at herself in mirror on the wall. It was hard for me to look away, and as soon as I started to, it was too late. We met eyes in the mirror.

​

"I'm sorry! I just woke up and didn't see you there," I stammered out as I turned back to face the wall.

​

She scoffed. "Yeah... right. You should be sorry that you kept me up last night," She replied.

​

I froze a bit, but had to say something. "Sorry, we tried to be quiet coming in last night."

​

"Quiet coming in, or quiet cumming?" She shot back sounding annoyed, "I heard everything."

​

I had no idea what to say back. "I'm sorry, I guess both," I said, looking back over my shoulder to see what she was doing. She was already looking at me through the mirror by the time my gaze made it to her. I couldn't help but look at her ass again.

​

"You're a horny one aren't you. Do you like looking at me?"

​

I had no response again, but she broke the silence. "It's okay, you can look," She said with a devilish smile. Without saying anything I turned away from the wall to face her. I sat up against the headrest and looked at her perfect ass as she brushed her hair in the mirror.

​

"Do you like what you see? My ass?" She asked nonchalantly. I nodded my head in response, still at a loss for words. "Yeah? Does it make you hard?" she asked again just as casually. I nodded again.

​

"Do you want to pull those covers down so I can see?"

​

I didn't say anything, I just listened to her and pulled the covers down. I was wearing black briefs and my cock was throbbing, pushing hard against the cloth.

​

"Wow, what a good boy. You do look hard," She said, looking at my crotch through the mirror. "Do you want to take those off? That looks uncomfortable."

​

I nodded without saying a word. I pulled my briefs off as she watched intently through the mirror. My cock stood upright, almost pulsing from how hard my heart was beating. I wanted to take it in my hand and stroke it, badly.

​

"Do you want me to help you with that?" She asked, putting her brush down and turning around to face me. I nodded again, still not saying a word.

​

"Are you going to be a good boy and do what I say?" She asked. I nodded for the 10th time.

​

She walked over to the bed slowly. She climbed up on top of me similar to the 69 position and put her ass in my face, teasing me by wiggling it. "Are you going to lick me?" She asked, waving her ass in my face. I didn't need to be asked a second time. I pulled her g string to the side and dove my tongue into her pussy. She let out a sigh and backed herself against my face, grinding herself down on my face. She pumped my cock as I let my tongue run all over her pussy, clit, and asshole.

​

"You're a naught boy. I want to feel that cock inside me."

​

She pulled her ass off of my face and grazed her ass against my cock. She reached down between her legs, grabbed my cock, and sat down on it. "Oh, fuck," she said. She immediately started bouncing on my cock, hard. I grabbed her ass harder than I had ever grabbed Haley's and thrust my hips as her perfect ass clapped against my groin.

​

With Haley gone, we didn't have to be quiet. I moaned loud, and she did even louder.

​

"I'm not going to last long," I warned her in between thrusts.

​

"That's okay. I want you to cum inside me, like I heard you do last night," She replied.

​

That might have been the hottest thing someone had ever said to me. I pulled down hard on her hips, thrust mine forward and groaned as I felt my cock erupt. My hips locked as my cock pulsed over and over. She moaned "fuck yes, good boy" as she planted her ass on me, letting my cock cum deep inside her. My body relaxed as my orgasm subsided and she giggled.

​

She slowly pulled herself off of me, and I watched my cum drip out of her and down my shaft as she dismounted me.

​

"Lets clean up. Haley will be back soon," She said with a smirk. "And make sure you come back and visit Haley again sometime soon".
