Jeff looked as Jenny sauntered her way over to him, she stopped right in front of him and leaned in to whisper "take of your clothes we are going to have some fun while your program does what it's supposed to do." Jeff looked at Jenny to see if she was kidding, but saw her take a few steps back and began to undress. Jeff quickly began to undress to when he realized that she was being serious. When they where both fully undress Jenny told Jeff to sit on the bed. Jeff complied and saw Jenny kneel down in front of him, she then moved his legs a little further apart and grabbed his dick.
Jeff was very surprised by how his girlfriend was acting wondering what she did on the chronivac. Jeff however didn't have to much time to ponder, when he felt her mouth wrap around the head of his dick. he quickly felt himself getting harder and harder by the minute and it didn't take long for Jenny to start giving him a blowjob , he threw his head back in pleasure and put one hand on Jenny's head and the other hand on his bed to help keep him up. he then felt himself start to change, he didn't really notice what was changing as all of his focus was on his dick and how good Jenny's blowjob is. Jeff then felt his dick start to shrink rapidly in Jenny's mouth and it didn't take long for him to feel her tongue in him instead of out on his dick. Jeff quickly straightened up and looked down, only to see his vision being blocked by two rapidly growing mounds. Jenny must have sensed his worry and panic, because she started to eat him out harder. with his focus now on the rest of his changing body he felt the sensitivity of his body. he felt his ass and breasts expanding, his hips widening, his waist curving inwards. Jeff then felt horns growing out off his head, his eyes changing, his body growing taller, another pair of breasts coming into existence, and he felt his abs hardening. Jeff's mind was in a whirl as he felt close to cumming, he fell back on his bed and started to rub his tits, while his mind started to change, he felt his new name and gender start to override his old name and gender. Jeff then felt a tail pop into existence as he climaxed and the stuff that Jenny changed of his old self died being replaced. Kat got up from the bed being careful not to knock over Jenny as she did so. already feeling ready for another round, Kat grabbed her girlfriend at tossed her onto the bed. Jenny was a bit surprised by this, but quickly recovered and waited for Kat to ride her large cat dick cowgirl style. Kat climbed on top of Jenny and began riding Jenny's cock like no tomorrow. after they both came Kat looked a Jenny and asked what she wanted to do now.
