Track. GF is unable of sucking BF due to intense pleasure

This guy wanted his GF to blow him while being fucked, in the wish that she would turn into a sexual dynamo. But the situation backfired. She was so well-fucked by the other man, that she was absolutely unable to coordinate her sucking. Furthermore, it i delicious to watch closely the pleasure-contorted face of the pretty girl. The BF gets so pissed off by the deception, that he angryly commands the man "fuck the shit out of her" as a way of revenge.
