You're gonna want to start by sucking on a GIGANTIC dick. Seriously, find the biggest one you can. Preferably a black one. There's a point to it, just keep reading.
Suck that cock with all your heart. Lick his balls, stroke the shaft, deep throat it until you're gagging on the gargantuan pole stuck down your esophagus. Listen to his moaning and groaning, sucking for hours on end.
At his climax, pull out and aim the dick at your forehead. The ejaculation will be so strong from your intense fellatio skills that it will literally shear off the top of your head, leaving you to fall to the ground, half of your brain on the wall behind you splattered with hair and gallons of semen, the other half a gooey, trembling, worthless mush stewing with male ejaculate in your skull. Your lifeless body occasionally twitches when the few complete nerve endings it has left in its brain send off a spastic single.
Don't stop there. Let the black man fuck your brain with his giant dick. If you completed the head-shearing successfully, he should be able to fuck all the way down into your throat through your gray, dying brain matter. The feeling of the slick brain on his gargantuan shaft will be the most intense pleasure he's ever felt, due to the lubricating qualities of the massive amounts of blood being poured out of your half-brain.
Finally, let him cum again, this time with a force so strong that it will tear your entire upper body in two. The beautiful, pure mixture of your blood and fecal matter and his semen will cover the walls, and he will pull out, with the very brain cells that told you to love your mother as a child and post the OP lingering on his quivering, huge cock. He will clean it with your beautiful tongue, which he can keep as a souvenir of his greatest orgasm. Then, he will display your body in the town square for all to see, the model idiot who asks this question on /p/.
