This sub used to be able to take a lot when ballbusting which impressed me.

But he's a bit rusty and out of practice.

Well, I'm here to boot that rust off him.

A few easy ones at first, but I gradually build up harder and harder. He tries not to let it known how much it's hurting - but he can't contain.

This gets harder and harder until he finally crumbles to my feet. This has to be a hard reminder!
