He plays with her ass and pussy.

He grabs Eve's legs and pulls them up towards her chest.
Her pussy is on display for both boys, even with her legs tied.

Eve loves it.

'What is Richard going to do to me next?!?'

He spanks her tight ass a few times, just to see what it feels like.
Steve likes the sound too, trying to move in for his turn.

Derek waves him off for the moment and moves his hand to her pussy.

Eve begins to squirm happily.

'Finally!'

Like, well, a kid playing with a new toy, Derek is really excited and vigorous in his ministrations.
Steve looks on with jealousy.

After a few minutes, he moves and Derek can't shoo him away this time.

He moves in around his friend and latches onto Eve's left breast to suck on it.

Something feels off about this to Eve...
