What muscle is he controlling here?
That's him sucking his penis up into his body and moving his inverted penis through his stomach cavity.
It's called Nauli-exercise. Yoga magic of some kind, I used to do it, but I can't remember why tho.
He just has a super muscular spine is all.

You just suck in your gut as far as it goes and then flex your abs. Easiest on an empty stomach.
