I don't really...

I don't really fantasize anymore
my mind got tired of trying to recall
the feel of your hand on my thigh
if I want to get off, I read a dirty story
usually something dark
dark does it for me, every time
though I've branched out
I like exhibitionist/voyeur stories now
group sex, especially if someone gets pregnant
and something about sex on a bus
gets me off
but there are only so many
different ways to describe
sex on a bus
a train is ok I guess
something about the crowded space
perhaps
but always back to the dark ones
sooner or later
