Preface: this happened around 6 years ago

At the time my gf & I were living together in an apartment with a couple friends. Well turns out we're all pretty damn sexual. lol Multiple threesomes, free use gf etc.

Well one evening she had a friend of hers over to just hang out & game, something that happened pretty regularly. They ask me to play some Monopoly with them & since I had nothing else going on that day I agreed. Well turns out they like to drink while gaming. lol

We're all chatting, drinking & having a pretty great time. Then my gf just flashes her tits as kind of a drunken impulse in front of her friend & I was pretty surprised because I didn't know this other girl that well, but she just laughed it off & said "It's not the first time". Which absolutely piqued my interest. lol

Turns out they used to fool around before gf & I got together. And this delved even further into her saying she seen the couples tinder that gf & I ran together. I admitted that we ran it to get laid. lol

Well that's all other girl needed to hear apparently because she started drunkingly making out with my gf while I went down on the new girl from behind. We eventually moved it to the bed where the girl told me to fuck my girl while she ate her pussy & I swear to God my pants were off in a split second 😂

We're going at it for about an hour, switching positions & just all around behind sluts. Turns out our bedroom door wasn't closed & one of the roommates came home from work & just laughed at us. "Didn't know there was a show in town" lol We go for a little while after that & all finish up. Gf says I can cum in her friend if I really want to, which surprised me hell of a lot because I was holding back the entire time so I wouldn't. lol I give the girl a look & she says she wants it. So that's all I needed.

After we all get cleaned up & are saying our farewells I end up walking her friend to her car while gf decides to make some food. Well the friend wasn't quite satisfied & said she wanted me to herself for a minute, well that minute turned into us fucking in the hallway of the apartment building & cumming in her again. We finally say our goodbyes & I go back upstairs where my gf says she could hear us. lol Which means the other apartments probably could to.

Needless to say we never finished Monopoly. 😂
