"Claire, play with your tits for a while."

Claire grabbed her tits and started massaging, lifting and dropping them.

'Damn, the book!' thought John. 'She's doing what I say!' John thought for a moment about the consequences. Then he decided to give ol' Paul a helping hand; him being a good guy.

"Claire, I got a great solution to you and Paul's problem," said John, never taking his eyes off Claire's tits.

"What?" said Claire, confused and blushing at playing with her tits in front of John.

"Let Paul titty-fuck you while you masturbate. That way, he gets off, you get off, he gets to feel your boobs, and you get to feel his dick and technically remain a virgin! Oh, and let him cum on your face. You'll love that! Sounds great, right?"

Claire brightened up a bit, "Yes, it's perfect! Thanks!"

"How about repaying me then?" asked John.
