This guy doesn't even need a real reason to get mad at his gf and come up with a kinky revenge plan. Maybe it's just his deviant desire to see her get nailed by another guy being so close he can feel her pleasure. He has her blindfolded and tied to trick her into making this nailed up sex desire a reality and by the time she finds out it's another guy banging her doggystyle she is too kinky to stop. Penetrating teen perverts!
