Simon is all excited about how his already hot brother Adam will now be not only gay but have a 16" cock when suddenly the door smashes off its hinges, splintering as this huge missile of meat rockets through it. And it's big enough to be a real missile too, for all that it's Adam's penis. Simon belatedly realizes he must have hit the mark for feet instead of inches.
Worse, his titanically hung brother is now instantly gay and Simon finds himself crushed against the wall by the massive member, the only thing keeping his sexually crazed gay brother from ramming it up his ass is the fact that the head of the penis is now wider than Simon's ass. But that doesn't stop him from getting an enema of cum as Adams matching balls begin churning.
"Aighghgh!" screams Simon, crushed into the sheetrock as his ass is force-injected with literal gallons of jizz.
