What's the button you plan to push?
He's a total brainslut
You never did anything at first, obviously, but Finn's super turned on by brainfucking. He's talked to you a lot about how much he'd love to get his head filled with cum and become a willing **** to you or anyone else who wants to fill him with cock. The idea gets you rock-hard too, so obviously that's what you want to try out for his surprise.
