20F me and my friend adopted an open masturbation policy that we read about from a reddit story, it lead to me fucking her boyfriend

Me and my roommate / best friend Katie have this like, open-masturbation policy thingy going on in our dorm. It all started actually when we were reading reddit sex stories, lmao, kind of ironic. Honestly though, if anyone reads this, you should give it a go. It's like, so annoying trying to find time to get off when you're sharing a tiny room with someone else. But with classes being all hybrid and events getting cancelled, we're always stuck in the room together. Plus, we're like, super comfortable with each other. We both have toys and it's not like we can hide it from each other anyways. So, we just decided to be cool about it and if we wanna get off, we'll just do it. No need to be embarrassed or anything.

The first time I tested it out, Layne was out at one of her classes and I was like, "time to get down to business." But she came back early and caught me in the act. I was just like, "hey girl, what's up?" and she was cool about it too. We've had a bunch of scenes like that since then. Sometimes we'll pretend like it's not happening, other times we'll hype each other up and offer compliments. And sometimes one of us will start and the other will join in too.

One time all of our classes were cancelled and we basically had a masturbation marathon. We didn't bother getting dressed and just kept going at it every half hour or so. We even put on some porn and used our vibrators together. We were sweating like crazy and just going at it for hours. It was so hot.

Anyways, it's like, not a big deal or anything. It's just two friends helping each other out, you know?

One day I was having a masturbation session when Katie and her boyfriend came back to our flat, I was busy watching some BBC porn and had it on pretty loud, usually we tell each other when one is going to bring a lad back...for obvious reasons lol.

Sure enough, they both walked in, I looked up in horror as I saw Katie and her boyfriend stood there, watching me masturbate. I didn't know what to say I was that embarrassed, I just came out with 'Hi guys'.

It was pretty awkward after that, and I think I heard Katie and her man having an argument because he was staring a little too much. And he kept bringing it up to her. I can totally understand her getting pissed off about that. Anyway, one day soon after me and her were chatting, she said she was going to go out to the shop & would be 20 minutes or so. She left, I decided to masturbate. Soon into it I heard the door open, me thinking it was Katie, I just carried on.

To my horror, it was not Katie. It was her boyfriend. If im completely honest it really turned me on, he was stood there, in a trance, unable to take his eyes off me. I just carried on like it was normal, my pussy between my fingers & moaning as I orgasmed. I don't know what it was, it was turning me on more and more, he carried on just standing there bewildered.

You know when you get so horny that you just do anything? Yeah well that's what happened next

I looked up at him, asked if he wanted to give me a hand, he slowly walked over and started fingering me, It felt so good. I had completely forgotten it was Katies boyfriend at that point. Eventually It lead to us having sex for about 5 minutes, I told him to rail me as hard and as fast as he could until he came before Katie came back. It was the best & hottest 5 minutes I swear to god. It felt great. He came deep inside me just as I creamed all over his cock and we both quickly got cleaned up and put the tv on talking like normal. It was just as well because Katie came home pretty soon after, thank god.

We never managed to have another encounter like that because Katie and her boyfriend kept arguing & broke up pretty soon after that, however im still friends with her now! we have a great friendship and in some ways I feel like adopting the masturbation rules made us closer friends
