Derrick stretched, then sat up groggily in the tall grass. He was naked, and his belly seemed swollen. It wasn't until he stood up that he realized just how swollen his belly was. He felt overbalanced, and really weird. Even odder were the sensations of his body. He felt his rump and found a new opening - or maybe that was an old one -0 he remembered being mounted by the billy goat. Then his eyes widened as the sensation of movement came from within.
Derrick headed for Circe's palace. It seemed he was going to eventually have a baby goat. How would that be affected by his vacation time? Or more importantly, what happened when he delivered. He was able to get back to the palace and found Circe relaxing by her pool. The woman looked up and grinned. "Looks like you have an extra passenger. What got you pregnant?"
"A goat." Derrick felt no shame or embarrassment at the admission. "What happens when I deliver?"
Circe shrugged. "Depends on what you are at the time. You will become a fully female version of whatever you are and the newborn will come out as the proper offspring."
