因为出轨他的女友而变成了绿帽奴

This chick is so mad at her boyfriend for cheating on her she's willing to do anything to punish this schmuck, even invite her ex to have sex right in front of his eyes. She gags the poor guy to keep him quiet and ties him up to make him just lie there and watch. He feels humiliated like never before, but also a little horny, the fact he would never admit to anyone. His first cuckold experience comes as a real life-changing shocker.
