After Mark cheats, his wife Lisa doesn't leave. She makes him watch her take revenge. One rule: she chooses. One condition: he stays in the room, silent, hard, and useless. No touching. No joining. Just eyes on every thrust. When she finally picks Simon—a tall, thick, unflinching Eastern European swimmer from Mark's new gym—the payback begins in their own bedroom. Lisa rides him raw, takes him deep, while Mark sits in the corner gripping the armrests.
