Positioned perfectly, I watch as my ex masturbates, her back to me. She's on her knees, legs spread, fingers circling her clit. Her other hand reaches back, spreading her ass cheeks, giving me a clear view of her pussy. I stroke my cock, matching her pace, our eyes locked in the reflection. She's close, her body tensing, her cries echoing. I explode, my cum splashing onto her back, marking her in our shared, heated moment.
