But a few times we've gotten naked and made love in public parks (nobody obviously watching.
A few times I've talked her into walks in outrageously sexy clothes (bushes showing through translucent shorts, hard nipples through tight tops), which led to later sex in said park, once with her bottomless and orgasming while people below could see her still-covered top. I don't think her muffled moans could be heard, but I think her boobs were boucing a lot... they probably had a pretty good idea of what we were doing.
it all depends on who she is I would think. sometime the semi private gets one going more like croping a feel under the table or caressing her breasts from time to time. Now if it's a private "club" most anything could happen there.
