Oh gosh, we usually don't need much...
sometimes we like to use the under-the-bed restraints and a blindfold, sometimes we use a strap-on or dildoes on their own, and we often slap each other on the ass.
But 97% of the time we just jump on each other and go at it. Foreplay = lots of kissing and playing with underwear, before it drives us too crazy and we tear it off!
Oh, I guess we do use lube at times (especially if he's rubbing his dick on me as foreplay, I like that).
Oh god, I'd better stop now, this is too exciting...
