You hold him to your deal

“Fuck! What is that thing?” he shouts in surprise, “You're bigger than me hard when soft! I'm not having that in me. You'll wreck me.”

“You agreed, man,” you remind him, “And you already claimed your side of the deal by fucking me. I'm here to collect.”

“Fuck! Fuck! Fuck!” he gives out a litany of curses, “You tricked me. You fucking shit.”

You decide to be patient with him - you know that he'll be begging for you to fuck him soon enough.

“Calm down, Benz. I'm going to prep you. We're not going to rush things,” you say to try and calm him, “I'm not going to **** it. Let me remind you that I want you to be my mate. I want you to like bottoming so I'm going to damn hell make sure that you enjoy this.”

He looks at you and then at your cock and shakes his head, “It's just too fucking big. I know what I said, man, but it's just too fucking big. And it's not even hard yet. Fuck!”

You are happy that he is only commenting about the size of your dick and not about your idea of making him your mate. Things are looking up. You just need to get his pride and fear to shut up.

“Didn't think that you were this big of a pussy,” you retort in attempt to rile him up, “You willing to renege on a deal because you're scared? Afraid of pain? You a sissy or something?”

This riles him up as expected and he suddenly changes his tone, "Fuck you, man. I can take anything you can dish at me."

"Then take me in you, Benz," you smile, "Be a man."

Checkmate. Dumb jock logic never wins.

And just like that, Benz is **** to say, "Fine."
