Ballbusting and Chastity - Crushing the Cum out on my Tits

Wearing just a sexy pair of panties, I put my pet's balls in my testicle vice and start tightening it slowly. I alternate between stroking his cock and ordering him to masturbate while I crush his nuts. I love that the vice is see-through, so i can watch his balls get flatter and flatter. It's weird how they look almost white when they're about to pop. I love owning this set of testicles so I can do whatever I want to them. You can tell how turned on I am by how much i play with my big perfect perky tits. It gets me so hot to press my fingers into the bulging sides of his squashed nuts and hear him scream. I order him to cum on my tits, but he is taking so long that i just keep tightening the vice. He cums so hard when i tell him his balls are going to burst, then I rub the cum into my tits.
