Just kidding, this is just the tip of the iceberg. Gagged and tied to his own cock, every pull, twitch, and nod of the head is instantly amplified. I tease, he rolls his head back in pleasure, which pulls his cock forward, which makes him jerk himself upright again, until I start teasing him some more. if you've never seen a sub so entirely betray himself simply by nodding his head "YES!", I recommend giving it a shot. Hot and entertaining.
