You don't resist; deciding perhaps to trust the boy's magic a little further; even the painful changes of the magic box had been pleasurable to you. So you let the mechanized man move you around; you aren't surprised when it bends you over and suddenly shoves something up your wrinkled pucker; the great brute had a cock not quite as big as yours; but certainly around a foot if not larger; and it began to fuck you brutally. It's metal cock wasn't made for a good pleasurable fuck; instead it begins to tear your hole apart; blood dripping from the metal phallus as it thrusts into you without mercy. Tearing your insides apart is incredibly painful; but you also find it strangely pleasurable in your new state. As it keeps going it makes strange dry ratchet sounds; like gears stuck in a machine. When it finally seems to orgasm inside you; although you feel no fluids it starts pulling you forcibly to the wall; although you enjoyed some of what happened; you are definitely hurting and don't resist too much when it pulls you into what appears to be solid steel.
When you open your eyes you find yourself in a strange room full of corpses; or at least they look like corpses, but they are moving all over your body. The macabre dark spirit inside you finds this oddly thrilling and highly erotic. You allow your teeth to dig into and tear the flesh of the zombie like creatures molesting you. You can see one body pushing your cock into a hole in it's stomach; you enjoy the feeling of fucking it's rotting organs. You enjoy all of it; no matter how grotesque.
