Alex tied to the chair, not allowed to move, gets his cock milked

It is somewhat arousing when he's not allowed to show any emotions or even moan when I'm milking him. I cut off his face from the video because his facial expression was like he was not even living anymore. And that is right, that was the gist of this play. The price for any movement was me walking away and stopping milking his cock. He survived almost 10 minutes like that when I finally made his cock spit a nice, juicy cumshot!
