Your mind has been poisoned by the content of the devil - pornography. You have tainted your soul so much that all you can think about is masturbating and you see even the mundane of things, such as nuns, as erotic. Your mind has a way of twisting and tricking you, trying to lure you deeper and deeper into sin. Confess your sins to Step-Sister Morningstar and she may be able to cleanse your soul.
