I want to be someone's experiment

I'm openly bi, and for a while now I've had this huge fantasy of letting one of my bros explore gay shit with me. I want him to think he's coming in and he's just gonna get away with me giving him head or some shit, and then I flip the script on him. I want to see him hesitate and contemplate for a moment before he gets down on his knees like a good boy and starts sucking, and if he seems into that, maybe I'll even ask him if he wants me to fuck him. If he says no, I'll ask him if he wants to fuck me, and force him to make me cum down his throat if he wants to fill this ass with his load.

Just a fantasy, but holy shit does it get me hard lol.
