In college, I had an fwb leftover from high school. We were mostly platonic, because she had a long distance bf most of the time...but they were always breaking up for little stretches and in those stretches, we would fuck. A simple enough arrangement, haha.

One night she texted me because they broke up again--she swore it was real this time--so she came to my dorm and we got drunk on my roommate's booze and then she rode my cock on the futon. She was pretty trashed when we were done, so I told her I'd walk her back to her dorm.

When we got there, I got her into her awkward lofted bed and she passed out pretty much immediately. I was walking out when I ran into her roommate. She and I had met before and gotten along great, and I knew she was single but I couldn't really make a move due to the arrangement with my fwb--honestly I had no idea if she even knew about that. She asked me about the "breakup" so I told her what I knew, and then one thing led to another and we were making out on the floor of the dorm outside her door.

We started reaching down each other's pants there in the hall, but girls kept walking by with their shower caddies and giggling so we decided we had to go somewhere. I texted my roommate and he was back, so we didn't have many options. Before I could object, she opened their door and pulled me in.

My fwb was snoring while we made out. Since the bed was lofted, we just kind of sunk down to the floor. The roommate went to my fwb's desk and pulled out a condom, and we got our jeans off. I tugged her panties aside and found that she was drenched wet, so I rolled the condom on and fucked her from behind right there on their little area rug. The snoring never changed once as I fucked her deep and we both suppressed moans.

When I was done, I tied off the condom and tossed it in the trash, gave her a little kiss good night, and left quickly. On the way home I realized...I had no idea whose trash can I'd thrown that condom into.

But I never heard another word about it. I hooked up with my fwb another handful of times before she transferred to the other school. I hooked up with the roommate again a few years later after college, but neither of them ever mentioned the other to me.
