Getting Geoff out of the picture was very easy, Tim thought--all he had to do was set him back to conception--and then he'd go back inside Anna and... and someone else would pop into existence to conceive Geoff along with Anna, which would defeat the whole purpose of making Geoff young enough to get him out of the way.
That is, unless he could ensure that he'd be the one the Chronivac chose, which would mean being somewhat older in order to be a father to Kathy and Greg too. Tim quickly pulled up the program and checked Anna's age. She was twenty-eight. That would require almost doubling his age to match... did he really want to bang her that much?
Geoff then called up, "Need help finding it?"
Tim knew he had limited time as he saw Geoff's character begin to walk towards the steps. He had to act fast and he had to act now. First Tim entered the age change for Geoff--selecting it to be set to "conception", and then he doubled his own age to that of 32. Having done that, and hearing Geoff begin to climb the steps, Tim hit Enter, hoping he was in time.
Tim felt his clothes almost immediately grow a little tight on him as he felt himself begin to grow--but then as Tim went to take his shirt off he felt it shift and change in his hands to fit his form better. Curious as to how he looked, Tim stood and crossed to the mirror in the room and was surprised to see what looked to be a nineteen year old college student--just starting to fill out his previously lanky frame with muscle.
Meanwhile as Tim was growing, Geoff was losing muscle and height rapidly. This became obvious when he stepped out of his shoe, stopping to turn around and find them disappear right before his eyes. Anna's own eyes went wide at that herself.
"What's going on?" she managed to ask a moment later.
"I--uh--don't know," said Geoff as his voice cracked suddenly and unexpectedly. His voice hadn't cracked since it had stopped at long last during his freshman year of college. Which reminded him he had to get ready for classes--wait, classes? And why was he wearing these baggy clothes? Geoff was beginning to slim out to that of his college freshman beanpole look.
"Whatever it is, it---uh-- happened just after Tim went upstairs. Perhaps he knows something about it?" questioned Anna.
"Right, Tim, my Big," recalled Geoff as he began thinking of himself as a pledge to a fraternity, Chi Rho Beta. And Tim began hurrying up the steps once again in his stocking feet only to trip on his too long pants and to go tumbling down the steps.
"Geoff!" called out Anna and she hurried and knelt over him. She began to fuss as she looked over Geoff, and was quite insistent on giving a thorough examination. Thankfully there wasn't any blood, thank god, but he did seem to be forming something resembling a bump on his head.
"I'll go and get an ice pack and call your mother to come pick you up," soothed Anna.
"T--thanks--suh--Mrs. Smith--I mean DeLeon," said Geoff as his voice cracked even worse. Damn, he'd just called her by his own last name. He hoped she hadn't noticed.
Meanwhile back with Tim, he was now in what looked to be the prime of his life at twenty-six, completely ripped and fit, and he was now starting to think of Anna as his wife--sweet. It was working!
When Anna came back in to look after Geoff, the boy she was babysitting until his mother was coming to pick him up, she carried with her an ice pack. The boy was just beginning puberty and would soon be old enough to be trusted to look after himself, she thought as she handed him the ice pack.
"Thanks Mrs. DeLeon," chirped the eleven year old boy politely as he held the ice pack up to his head.
"Your welcome," said Anna with a warm smile, to which the boy answered with a hug. Aww, he was so sweet.
Tim began to worry as his abs began to smooth over as a little pudge began settling on his frame as he pushed past thirty and began thinking of himself as father to Geoff, Kathy, and Greg. It wasn't a tremendous amount, but it was the first sign that unless he continued to take care of his body, it was going to atrophy on him.
At this point, Geoff passed seven years old and hugged his mommy tighter, the ice pack falling to the floor as he did so. The world seemed to be so big and scary--and just getting moreso, but Mommy would be here to protect him.
"Aww, Geoff, honey, I'm here," cooed Anna as she picked her little kindergartner with babyfat still on him. As she did she heard a piddling sound and looked down to find Geoff wetting himself. Anna sighed, it would mean pulling out the pull ups once again.
Finally Tim settled at thirty-two, with a bit of grey appearing at his temples, and a very thin layer of fat smoothing out his abdomen.
"Tim," called Anna, and Tim left the room to see Anna holding a thumb-sucking Geoff somewhat away from her, taking off what looked to be his underwear and leaving him completely nude. It wouldn't be long now before Tim and Anna would be conceiving him, that thought made Tim go hard.
"Geoff wet himself, can you clean it up while I change him?" asked Anna.
"Sure, Anna," he said as he hurried down the steps for the paper towels--intrinsically recalling where Anna had put them.
The toddler Geoff began to fuss as Anna carried him out of the foyer and up the steps to the changing table.
"No change!" whined Geoff.
"If you'd stop fussing, it won't take long at all," Tim heard Anna say as he made a turn for the kitchen. He took his time getting to the paper towels, and just as he did so, he heard a call from Anna upstairs.
"Tim... could ya come up here... I'm really horny."
Tim turned around to find that the urine that Geoff had peed was gone and he bounded up the stairs and into what he now thought of his room with Anna, who laid down on the bed in all of her seven months of pregnancy and naked herself. It wouldn't be long now at all. Tim began to strip as quickly as he could and climbed into bed and positioned Anna on top to keep from hurting the baby. He had wanted Geoff out of the way, but he didn't want him dead.
As she rode his member her pregnant belly started to shrink, going back in months. 4...3...2....1. Relatively quickly Anna's belly lost all traces of being pregnant. The little Geoff fetus got smaller and smaller, becoming a fertilized egg then a sperm separated from the egg. Geoff was now an unfertilized egg waiting to be impregnated.
As the months of pregnancy practically melted away, Tim noticed Anna became more fierce in bed, causing the backboard of the bed to thump against the wall in the master bedroom.
Anna was moaning as the two ground their bodies together. "Yes...yes...mummmm," moaned Anna's as she approached orgasm. Sweat covered the two as they began to thrust faster as he was reaching his peak as well. Anna's muscles in her vagina started contracting as she screamed out in pure delight. This caused Tim to reach his orgasm, ejecting streams of semen into the awaiting womb of Anna, joining her in the euphoric feelings of pleasure. Tim and Anna cuddled together on the bed in the afterglow of sex as one of Tim's sperms made contact with Geoff's egg, impregnating her once again, and making Geoff Tim's son.
