Ass....as long as there something to suck on expesaly if they sensitive...but an ass get me hard all day long....but my fav is a nice pussy and be able to look up at the tits
I agree, Sweets although my tits are huge right now and just don't seem as comfortable during sex hahaha the big bouncy boobs don't so it as much for me as a nice round size with a good nipple!
