Slave finds himself at my mercy again.. His mouth is gagged, taped, and his face is completely wrapped. Hands cuffed to his side There is just a small enough spot for his nose to breathe through- When I let him hehe..  I sit on his face, using my full weight to control his breathing. I want to see how much he can handle.  After spending plenty of time using his face as my chair, I decide to have some fun with my vibrator.  I gently use it right on his sensitive frenulum, teasing him right where it counts. I end up being able to ruin him before he's able to get fully erect or feel my hands..
