Jon awoke face down on his carpet in his room. He felt kinda sore and smelled awful. He could feel dried sweat (not his), dried juices all over his body, and he tasted cum and pussy in his mouth. Damn Sarah. Such a slut.
His door was pushed open by his Golden Retriever, Jack. Jack immediately trotted over to Jon and began licking him.
"Hey boy," sighed Jon. He dreaded the next two months. Suddenly his dog leaped onto him, knocking him on his back. "What the-" started Jon, but he suddenly froze. His face was directly under Jack's sheath, and he could see the scar where Jack was fixed.
Jack began panting heavily. Jon felt himself being pulled up towards Jack's crotch. His skin grew as he attached to Jack, enveloping him. Jon was now in total darkness. He could feel himself shrinking and splitting in two, both halves of his body rounding out and losing detail. His legs curled up into I waist, which was separated from his torso, arms, and head. The shrinking stopped, and Jon was ever so slightly squeezed by Jack's scrotum.
Jon had become Jack's balls. As he sat there, unable to move or see, he suddenly began tasting and smelling cum as it oozed from his body. He began bouncing, and he assumed Jack was wandering the house.
The bouncing stopped, and Jon felt something wet brush across his body outside the scrotum, making him shudder involuntarily. Jack was licking Jon.
