Jeff needed to be filled with cubs, and only until the day she would give birth to them will she ever be satisfied. As Mike, her former father, grinned down at her with a smile across his face he kept pumping her, again, and again, and again. Jeff was in complete and utter bliss each time she orgasmed to her new mate, and felt him dominate her insides.
The two fucked so much that Jeff's pussy felt numb and raw from Mike's powerful cock. He looked down at her, the two of them sweating profusely as Jeff physically appeared two to three months pregnant just from Mike's seed alone. However still she had the desire to continue, but part of her was glad that he stopped.
"Ugh! Looks like this old boy is tapped out for the day, what a shame." Mike said
"Aww," Jeff sighed as she looked up at Mike.
"I know, I’m a bit disappointed myself, but how about we do this again tomorrow? You know, as long as you don’t start showing signs, my kitten." Mike purred and stroked Jeff’s face.
Jeff smiled and put one hand on her stomach then Mike pulled out causing Jeff to let out another yowl. After Mike was out of her, Jeff looked down and saw the semen oozing out from her pussy, and once Mike noticed this he got down on the floor and licked it until it was clean. Jeff growled in ecstasy over this until Mike got up and sat back down on the couch with her and said,"You'll have my first, and probably largest litter yet. I remember when your face was that dirty as a little boy, but now.... heh, now that doesn’t matter."
Jeff blushed a bit and wrapped an arm around Mike, nuzzling his strong chest and purring against it. Mike chuckled at this and said,"You remind me of your mother, I wonder when she’ll come join the pride with you. I just know she'll love it, don’t you think Jenna?"
Jeff paused and blushed once she heard her new name and asked,"Jenna? Wait... did you just...."
"You’re a girl now aren’t you? Hell, you'll be pregnant before too long. I thought I should at least rename my own boy considering..." Mike said and Jenna looked down at herself and nodded.
Mike turned on the TV again to some football, and Jenna sat with him and watched as Mike put his arm around her. Jenna paused and thought for a moment about her future, and wondered if she should tell her father about the chronivac and give it to him as a present for becoming mates with him, or she could alternately use it to change others like this.
Jenna imagined a world populated by lions, and each lioness would happily serve their master. There were even more possibilities too beyond that with the chronivac, and she couldn’t wait to see what happened next.
