My first girlfriend (Anna) after college was a little gorgeous brunette slut with a perfect 5'1" body and D cups. Abs without trying. Every guy who passed her tried to make eye contact if they weren't staring at her perky tits.
She confessed to me that she and her female cousin Kailey (18 months older than her, more like sisters than cousins, very tight-knit family) roomed together in a dorm during her freshman year of college and had a bit of an "arrangement." Her cousin was a sophomore and had already become a college slut. My girlfriend was a slut well before she got there, and after the first couple weeks, realized that no one outside of her little circle of friends could keep track of all the hookups. So she went wild like her cousin did.
Kailey was a bit on the chubbier side at the time, but had dark auburn hair, was pale and freckly and had a set of beautiful tits. Basically she was fit enough that guys would fuck her without hesitation after a few drinks. Looking back, her body was definitely pretty nice, but next to my girlfriend's, it probably looked a little schlubby. Anyway, they would go to frat parties and since they weren't associated with a sorority, the frat boys could fuck them with zero repercussions whatsoever.
Problem is that they shared a tiny dorm room, maybe 10 by 10. On Friday nights during the first couple months of school, they would race to see who could "claim" the room first, which, naturally, didn't work out so well.
They were absolutely hammered one night and had what my girlfriend called "two super-hot upperclassmen athletes" wanting to go back to their dorm room, since they lived off-campus and a long walk from the party they had been at. So they decided they were just going to go ahead and do it in the same room. At first, it was dark in the room, and my girlfriend said she tried to stay under the covers out of modesty. But soon they were both moaning ("his dick was huge and we didn't have any condoms") and one of the guys turned on a desk lamp. They looked over at each other getting fucked out and her cousin said "oh my godddd," and came like 30 seconds later from her fingers. The guy she was fucking apparently wasn't finished, so he got up and squatted down in front of Anna and, being totally wasted, she just sort of rubbed the juice off of his cock with her hand and then popped it right into her mouth, tasting Kailey's pussy off of it despite the laughable effort to "clean" it. Both of the guys fucked Anna, then came on her and left. The girls went to sleep and the next morning, Kailey said something like, "I guess that's going to work from now on, if that's cool with you" and Anna just nodded and was like, okay.
For the rest of the year they fucked in the same room every weekend, totally on display for one another. Somehow rumors never made it very far about them, as it was a larger campus. She said most of the guys just assumed they were regular roommates, but the truth is that they were cousins who were down with P2M on each other. They never hooked up themselves, but she said that she fantasizes about MFFM foursomes all the time and never had beforehand. Her cousin studied abroad the next year, and then my girlfriend studied abroad the following year, so they never lived together after that. As far as I know, I'm the only boyfriend who knows about it.
