You come home from work and hear me talking to someone in the guest bedroom. You quietly open the door and see me with a strange man. I'm undressing and touching myself. You want to stop me but you're also super aroused and feel yourself getting hard. You decide to sit and watch me. You slowly open the door more as time goes on. She is bouncing on this guy's cock and letting him really pound her from behind which ends with her begging for cum on my face... She comes to the door face covered still, and teases you about watching and jerking off. She knew you were watching the whole time.
