Newly bisexual Tricia, thinking a bit with her dick after having gotten an erection from the girl on the cover of Jeff's magazine, decided to see what her boyfriend would look like with his sister Jamie's aged up to about 20 years old adult woman body. She used the Chronivac to swap their bodies below the neck.
Tricia couldn't help but wolf-whistle at her boyfriend's cute face above those big D-cups (he had given his sister). "My what cute boobs you have, Jeff."
Jeff looked completely embarrassed, "You made me a woman?" He was surprised that his voice came out sounding the same.
"Not entirely," Tricia winked, "I left your head the same just like you did with Jamie. Though that's not all you have in common with Jamie now."
Jeff finally started to notice some details about his new body, "You gave me Jamie's aged up body? Why?"
"Isn't that what you wanted when you gave me a dick and made me bisexual and then talked about Jamie so much?" Tricia laughed, "Did you give your little sister the body you hoped to get pounded in?"
Jeff shook his head no. He certainly hadn't been planning that far ahead. Though his nipples were very hard and he realized he was very wet and his hot girlfriend had cute dick between her legs all excited and ready to go, and Jeff started to wonder if his girlfriend was right and getting pounded was his idea after all.
