I'm soaking in the tub, the warm water relaxing my muscles.Suddenly, I notice you standing in the doorway, staring at my naked body.Especially my big, round ass, floating in the water.Instead of getting mad, I smile invitingly.'Like what you see?' I purr. 'Why don't you come closer?'You hesitate, but my words draw you in.You strip off your clothes, your big, hard cock springing free.You sit on the edge of the tub, your eyes glued to my ass. 'Play with yourself,' I instruct, spreading my cheeks. 'Masturbate until you're ready to explode.'You wrap your hand around your shaft, stroking slowly. I moan, squeezing my ass cheeks together. 'That's it, baby. Get yourself nice and hard.'Your breathing quickens, your hand moving faster.I lift my hips, my ass breaking the surface of the water.
