Gagged and bound, fucked by a fucking machine

The woman allows herself to be blindfolded, bound and gagged. She's exposed and can't tell when to stop. The man pricks her tits with needles and then does the same with his pussy. The woman does not know what he is doing to her and reacts naturally to the pricks. Then the man jerks her off with a vibrator, making her very horny until she asks him to stop. The man arranges for a fucking machine that pulls out moans of pleasure to fuck the girl.
