*cough* in the biology lab at a university, he was wearing a lab coat.. couldn't help myself
I have always wanted to make love on the beach/in the ocean.. dunno why. Or even in the rain in a field somewhere... the rain kinda does it for me though, kinda get all sorts of "aggitated" during storms.
But I think my favorite would definently involved a beach/storm somewhere.... with someone I was comfortable with.
And that's about it.
