Jeff wanted to gift the father of the fox pups she was pregnant with a more human body so that they could more easily date. She probably wasn't thinking very clearly given how wet her vixen muff was and how hard all ten of her nipples were at the smell of hot guy fox filling her bedroom air.
Jeff was busy scanning on the Chronivac for neighbors who were currently outside so that they wouldn't be too out of place when she swapped their human body parts with a fox's. Jeff eventually picked up that her neighbor Chloe a few doors down was out in the backyard practicing her cheers. Chloe was the hottest cheerleader in school and would barely even talk to the old male Jeff even though they were relatively close neighbors. Chloe had been a huge bitch to Jeff and Jeff started to think that Chloe would deserve to have the body of a fox to better resemble how she treated people.
As Jeff made the swap she started to hope that the sort of male fox with a human vagina who had been Chloe might find the formerly lady fox with Jeff's former penis and experience a pregnancy of her own.
Jeff took a few minutes to appreciate how hot her boyfriend was now. He really filled out that cheerleader uniform. Even with a sports bra on it was pretty clear how big his breasts were underneath and Jeff couldn't wait to set them free. He looked so cute with his hair in pig tails. He had sweet lady abs on full display with a cute little diamond piercing in his navel. His (still so sweet smelling to her) fox penis was erect and tenting his miniskirt up to reveal even more of his gorgeous long girly legs.
