this girl that used to use ME as a late night booty call (can't say i ever complained) used to squeeze my dick with her vagina.
in fact, she knew it would make me cum within a minute or two, so we used to make it a game, because once i made her cum, she wouldn't be able to hold onto the squeeze for at least another minute or two during or after her orgasm, so it was kind of a race. she would squeeze me, but if i could get her off, i would get the necessary "release" so i could keep going. then she'd clamp down again, and i'd go at it super hard to make her cum again so she would have to release me.
this could go on for four or five orgasms for her, until i couldn't last any longer, then i'd spooge a giant load all over her.
maybe i should hit her up on facebook some time.......
