I Didn't Think You Would Fuck My Step Bro Before Fucking Me

You're the best big brother I could have ever asked for.

But come on, you don't have to do this. It was just a stupid game and a stupid bet and you don't have to follow through with it.

Yeah, but I told him I'd fuck him if I lost.

He's my disgusting stepbrother. Nobody wants to fuck him.

Yeah, but he's not my brother. Besides, he's pretty cute and I hear he's got a big dick.
