I start playing with my bound pet, giving him a handjob with hard grabbing/squeesing of his balls.

I keep playing with his dick sensually, my magic fingers polishing his glans.
The bottom hand wasn't in the same mood.Hard grabbing/squeezing/twisting, strong slaps on his balls.Non stop.
His enstinct kicks in and tries to escape many times, but his moving is very restricted.

I give him a few small breaks here and there but I never leave his heart rate to drop until I'm done with him, which means 2 huge extractions, including post orgasm torment after each one.
