Rub his cock and play with his nipples

A little biting wont hurt, right? Feel free to squeak if you like.

You have him right were you want him! He is squirming on his back with nowhere to go while you nibble and lick his nipples and jerk his leaking cock at the same time. Maybe some gentle biting? Maybe a little tongue play? You smirk as you discover what drives him up the walls.
