Mark, starving, ran to the refrigerator, grabbing the ice cream out of the freezer compartment. "What have you done to me?" he asked between gobbling the ice cream down straight.
"You're turning into a pig. See?" Ty pointed out.
Mark wasn't able to eat the icecream fast enough, so he put it in the microwave, and while he was waiting for it to liquify, he chugged an entire bottle of cooking oil. Then it was time for the ice cream soup, which he poured down, followed by a gallon of milk, a can of chocolate syrup, a bottle of ketchup, and an entire container of raw chicken thighs in terriyaki sauce. Mark gobbled them all down without burping, watching in horror as his ass got fatter, his stomach as well, and he started to grow thick boar bristles all over his body as well as a full line of nipples.
Ty laughed himself silly watching his step dad gorging himself as he turned into a pig, his hands and feet forming into trotters, his mouth into a snout, and a huge pair of tusks began to jut from his lower jaw.
Finally, after chomping down a bag of raw potatoes and rooting through the garbage, there was nothing in the kitchen left for the man-pig Mark to eat. Except for one thing...
Mark, retaining his full human intelligence, along with his hunger, slashed his tusks straight across Ty's throat and then bit down hard, severing the spinal cord. Then, with glee and revenge, but mostly hunger, he began to eat the body.
By the time he was done, there was nothing left in the kitchen but a huge boar with human intelligence licking the blood off the linoleum.
