Ty was too exhausted to even watch as Lisa's body formed again, from his penis. He had collapsed, lying on the bed, eyes closed. He felt it, though. First her pussy lips forming around the base of his cock, and gradually, her whole pussy. As her body grew, he held it, her in his arms. Eventually the transformation was complete. He still felt her pussy around his cock, but it was now entirely separate from him.
"Lisa," he said. "Thank goodness you're back! I thought I had lost you! I was scared!"
He was totally unprepared for her response. "Cock scared too. Cock exhausted. Cock sleep now."
"Lisa? Is this a joke?" he asked, but she didn't reply. "Lisa? Talk to me!"
"Cock no talk. No listen. No think. Owner does thinking. Cock only fucks, and pisses, and sleeps. Cock sleep now!"
"Lisa! Snap out of it!" He shook her. "You're not my cock now. I'm not your owner, I'm Ty! You are Lisa! You have your body back!"
"Cock sad. Frightened. Don't like body. Want Cock body back. Was happy in Cock body. Why did owner do this to Cock!"
"You're not Cock, you're Lisa!"
"Fine! Cock is Lisa. Lisa unhappy. Owner mean to Cock. To Lisa. No more talk, no more listen, no more think. Lisa sleep!"
He kept trying to talk to her, and she completely ignored him. He got no response from shaking her. He noticed that she wasn't even breathing, which concerned him, but she wasn't turning blue or getting cold. He remembered that in a previous transform he had removed her need to breathe. She shouldn't need that in human form, but she must have redone it.
He is in a panic, yet he is so exhausted from the struggle that he can't do anything. She needs to sleep? Fine, he needs it too. Sorting this out will have to wait. He pulls out of her, rolls over, and falls asleep.
