So there you are, on your knees. You finally have a cock in your mouth.
The first thing you learn is it's more work than you thought it was. Your jaw tires quickly, but he's hard, horny and wants to blow a load down your throat. So you keep going.
He occasionally groans with pleasure. There you are, just like you dreamed. Sucking cock.
I love it. Some day I want to find someone with hyperspermia so I can get a huge mouthful of cum.
