I thought it was just a fantasy-something we whispered about in the dark. But the first time I saw her on her knees, lips wrapped around him, everything changed. The shock. The jealousy. The overwhelming arousal. I couldn't look away. And she didn't stop. Not even when he got rougher and rougher, or when I walked in. Not when she swallowed. That night shattered everything I thought I knew about our relationship... and about myself.

Now, there's no going back.

This is the story of how I watch her-and how it made me harder than I've ever been.
