Mrs. Grinch catches you, a masturbating peeping tom, jerking it to her through the bedroom window. You came up to the top of the mountain to get a glimpse of the Grinch and started jerking it once you saw her... well the Grinch doesn't take too kindly to situations like this. He takes his revenge in the form of making you suck his big fat hairy green GRINCH DICK!!! You're going to take it in the ass too. Serves you right. :)
