He can't help but notice her firm tits pressing against him, or the way her hips sway enticingly. She's aware of his raging erection, her pussy clenching in response.

He pushes his fingers into her wet heat, she strokes his cock until they can't resist any longer, fucking passionately, their taboo love consuming them.
