we were afterhour'ing with 2 great mates and my brother (i live with my brother) at my place. me and my gf decided to dj a little on my decks, told her she should change into a tight, white croptop for this which she gladly did. few hours later i suggested she could put on a seethrough sportbra, she hesitated for a little but changed into it and kept on DJ'ing wearing it while the four of us enjoyed the view
not the craziest story but it was a nice vibe overall with her enjoying getting looked at and teasing us all with her visible tits/nipples
sex afterwards was crazy
i might have a pic from that day somewhere, would have to look for it
