So i’ve got a mild story for you guys, but to me it was a lot of fun. Short background before the story, I (M, 21) went on a weekend trip with my whole family, including my girlfriend (F, 20) and my cousin (M, 18) we rented a big house, with a whole spa, including a jacuzzi. I’m also very close with my cousin, and my girl has an exobitionist side, but still kinda in the closet . So, to the exiting part. We went around 11pm in the jacuzzi, me, my girlfriend and my cousin. My brother went along also, but got out and left shortly after. The half of my family was asleep and we knew we weren’t goint to be bothered now. So at this point, we are in the hot tub, the room was dark, with just some cosy lights on, casually speaking about chitchat with my cousin, and al of the sudden i notice her shoulder straps are gone, so i ask her “where is your top?” And she replies saying it’s to hot to wear them. Her breasts weren’t really visible, since it was dark and they were submerged, but my cousin really got exited obvious. I really liked that my girl was topless among my friend, and never thought she dared to do this,i went next to her, subtle groping her breasts and still talking with my cousin, he didn’t mind the circumstances at all. My girl even went further, changing her seat, and exposing her breasts fully to him while doing so, sitting in my lap so i could grope her tits in sight of him, and just sitting there, boobs above water level so he could stare as much as he wanted. After all this it was around 2.30 am, and we eventually got tired and went to bed to. For my girlfriend this was really sonething new, and i’m still to this day amazed that she dared something like this! Thanks for reading guys, sorry for any grammar faults.
