He turns one into cum

As John fucked the blonde, she began to change. Her legs shrank into his cock, but she was too busy moaning in pleasure to notice. Her entire upper body then vanished. By the time she realized what was happening, her head was the only thing that remained outside John's cock, but that soon vanished into his cock as well.

John could feel the girl turn into cum, sloshing around as his cock grew bigger.

The redhead gasped as she saw what happened. John turned to her.

"Who said I was done with you?"
