Afterward, Mark and Amy both laid on the bed, breathing heavily. After a while, Mark stood up and tried to remove the dildo. For some reason, it was now red and when he tried to remove it, he felt a tingling sensation go through his body; sort of like when he became aroused.
Pulling his hand away, he watched as the red organ became semi-soft and then slide into a sheath now present. Wondering what was going on, he turned to Amy.
She was lying face down on the bed, a large cow tail twitching back and forth. Suddenly Mark could smell something. Realizing that the this aroma smelled nice, he tracked it to his wife. Suddenly he could feel his penis becoming erect. A voice from the bed said, "You know you want me."
Mark looked at his wife more closely, saw that her tail was up and figured, "What the hell."
Mounting his wife from behind, he proceeded to take her and both orgasmed over and over; the fact that he had a bull's penis and testicles and his wife now had a tail and genitalia of a cow, was completely forgotten.
