Make him beg for it

"Do you want me to put it back in?" you ask your sexy younger brother.

He looks embarrassed. "It just felt better when it was in there. I'm not gay." He quickly added.

You're now stroking your long fuckstick right in front of his face. "Alright bro, you're not gay. But you want me to fuck your ass?" You know your demonic cock is already altering his brain, making him crave it, more than anything else.

"Yeah, I guess. I know it sounds weird." His eyes are locked on your rod.

"Aright then, get on your back." As he rolls over you notice his morning wood is now rock hard. You guide your flared head to his entrance, and let it rest.

Carl smiles as he looks up at you. "Just put it back in." He orders.

"I don't think so bro. I don't think you really want it." You push just enough to let him feel it.

"No I want it. It felt really good."

"Put you're not gay. I don't believe that a straight guy could want it that badly."

His face is looking more ****. "Fuck! What do I have to do to get you to fuck me?! You need me to beg? I'll beg. Please fuck me big brother! Please fuck my ass!"

You know that you have him wrapped around your finger, but you want to break him completely. "Anyone can just say that, but if you're straight, I still don't really want to fuck you."

"Damnit! Fine! I'll say it! I'm gay!" You notice his dick jump and leak a bit of fuck juice. "I love fucking guys and sucking cock. And I really love your cock and I need it in my ass!"
