Rex activates the chronivac and makes a few adjustments. Jeff's mind grows hazy, and his body becomes hot. "W...what are you doing to me...?" Jeff asked groggily. "I'm just improving your new feminine instincts. Don't worry, soon you'll be enjoying sex with me so much you'll want to do nothing but! And, I made it so that once you're knocked up, you won't ever have an empty womb again. I'm about to make you into the lovely broodmother of our new herd!" Rex said enthusiastically as he slowly changed back into a magnificent buck. He positioned himself behind Jeff and mounted him. "Alright 'Jenn, time to become a sexy sexy mommy!" Rex plunged into Jeff's entrance eliciting a bleet of surprise and sexual euphoria. "N...no...I....I need to breed....no...I don't want to...g...get....bred.....mmmmmm.....I...I don't want my womb filled with your...f...fawns....oh fuck..." he was having a hard time resisting, his instincts demanding him to succumb, to submit and become a living sex toy and incubator. He just needed to fuck, needed to mate, needed to breed, needed to become forever pregnant! He couldn't resist anymore, his male self gave in, no longer was he Jeff, she was Jenn, the completely submissive mate of Rex, with no will of her own, she just had to obey and get pregnant, and she would be rewarded with pleasure, pure bliss. Her mind started to become more simple, "enjoying yourself Jenn?" Rex asked. "Yess master, I....oooooh....I love your cock! mmmmmm, I love being bred! More master! I need more babies inside of me! More of YOUR babies inside my womb!"
Rex mated Jenn for hours until the sun set. The next day it was the same. The two had many fawns which Rex gladly fucked, male or female. Rex was the alpha of the pack and he needed to prove it. Rex's favorite was Jenn of course. They mated almost constantly, Jenn's belly and tits always swollen to huge proportions. They lived a happy life together with their herd.
