We all met freshman year of college, we had a class together and just decided to study together for some reason, 3 guys and 4 girls.

One night, we were in one of our dorm rooms and one of the girls had gotten her hands on a couple bottles of whiskey. We were all taking drinks and got a little tipsy.

I was joking around with one of the girls when she jokingly told me to shut up, so I told her to make me and she gave me this pretty little smile before she got down on her knees in front of me and started undoing my pants, I just helped her and she started blowing me. Then halfway through, the other girls followed suit on the other guys, and the fourth girl took her pants off and pushed me to lay back on the bed then straddled my head. The oral is all we did that night.

After that, we all talked about it, saying how it was really fun, and decided on when we were in private then we would have free use of each other because we all found each other relatively attractive and enjoyed that night.

So that's what we did, free use of each other whenever we wanted while we were in private.

We used it as like an experimental time to see what we all liked: Oral, Intercourse, Anal, Threesomes, Orgies, the girls had sex with each other, us guys had sex with each other. Which all happened even more when we all moved into a house together during the summer before our junior year. We even began experimenting with ropes and BDSM since we had more privacy. We continued this for a couple years after college as well.

This free use friend group lasted for roughly 6½ years, I won't say why it ended because it is a messy and sad story....

But damn, it sure was fun while it lasted.
