As Jeff walked to and from the car with grocery bags, the chronivac did its job of applying the "selected" changes to it's mother and son subjects. Aiming to make Jeff the perfect partner for his mom, the program starts to change him. To be honest, he didn't change much physically. Sure, his body became more toned with a lot more energy; even Jeff noticed how in shape he felt as he carried the bags. However, it also increased the size and girth of his cock, now erect, to make it the perfect meat rod to go in and out of Sharron's pussy. Once Jeff had finished bringing the bags to the kitchen, he noticed his mother's attire had changed to a tight latex suit, hugging each of her now larger assets, with flip flops on her dainty feet. "Thanks for that sweety, now come back to mommy. She misses you." Sharron requests.
Sharron's husband, John, had a tendency to not actually do sexual acts with her as of late. With the excuses of being too tired or too old for it, Sharron would've eventually needed to look for someone younger to replace him for lovemaking. Scared to ever do such a thing with another man outside the family, her only via candidate would be Jeff. And sure enough, in this changed reality, Jeff was her mate. Sharron wore leather suits now that would allow Jeff to be inside them, fucking her as she went about her day. John still remained her husband however; but in this reality was glad his wife was being made happy, and proud of his son for doing so.
Jeff undressed as his mother unzipped the front of her suit. Now nude, he stepped into it, shimmying around to get comfy in the tight attire; though thanks to gravity, his head was between Sharron's boobs. That was fine with him, as he got to smell her sweat and pheromones, pushed up against her squishy tits. Jeff then sheathed himself into his mother's cunt, now strictly for his use only, filling her up completely. Wrapping his arms and legs around her back in the suit, Sharron would now carry him around as they made love.
Zipping up her suit, Sharron moaned from feeling Jeff's body pressed against hers again. However, she had work to do and started to put the groceries away, unaware that the suit zipper broke off and she was stuck with it on. Regardless, with Jeff thrusting his own hips to pleasure his mother, Sharron's movements further enhanced the experience. Her walking and bending bobbed Jeff up and down, making his rod reach deeper into her tightening pussy. This continued for a while, until Sharron finally climaxed as Jeff's tip poked her cervix. He did so as well, groaning as he spew a load right into her womb, just as he's supposed to in this reality.
With one load deposited, Sharron continued doing her chores, eager to receive more loving from her mate.
