After what seemed like forever, Cal's knot finally shrunk enough to slide out of Mark's well fucked hole. Cal went back to a corner of the basement and began licking himself clean, leaving Mark alone to inspect his own new canine cock.
Mark's sheath had covered over the red pointed head of his new equipment and was firmly attached to his abdomen. It seemed like the changes were over for now so he figured that he should get himself cleaned up before the cum dripping out of his ass made a mess everywhere. Grabbing a clean towel from the linen closet, Mark headed to the shower.
Cal watched Mark go into the bathroom and shut the door. Somehow he knew he wasn't suppose to be a dog, but he had a hard time remembering anything prior to humping Mark's face earlier in the driveway. Cal could hear the water running in the bathroom, but suddenly he heard something else coming from upstairs. Mark's little brother Toby had just come home and was upstairs rummaging through the kitchen for something to eat.
