Perfect punishment for a slut

This guy knows his slutty gf has been cheating on him and he has a perfect revenge plan for this shameless bitch. He has her tied and blindfolded in bed and invites a horny friend over to let him fuck this unfaithful whore any way he wants. The gal is shocked to say the least, but once she ends up sitting on her boyfriend's face and sucking his buddy's cock at the same time she totally loses control and even takes a messy facial. What a finish!
