Tim kissed Lizzy as he gasped as the tingle ran down his spine again. He winced as he looked over the bed and saw the pairs reflection in the mirror. Lizzy moaned with each thrust as Tim looked back at her as her stomach had become completely flat. Tim shuddered as his eyes grew wide, just like the old man warned, he'd just broken one of the major rules of the pond. The tingle returned, stronger than ever as he could feel his skin rejuvenating. Tim counted his age, he had gained twenty years from Marty, so he was only thirty-two. He gasped again as the feeling returned, it was much faster than before.
Tim looked back at the mirror, his first grey hair was already back to blonde, any early appearances of age were rapidly disappearing. "Oh shit." he muttered as he winced in both realization and pleasure as Lizzy finally made him cum. She slumped to the side, basking in the afterglow as Tim sat up. Looking around nervously at what had happened he walked over to the mirror. "That old man said it was a hour for a year, but this is..." he trailed off as he watched his beard begin to shrink in size. It was like he was getting younger twice as fast! Tim looked back and thought about his da- no, not his father, his....no wait....Tim grew puzzled, the ponds effects constantly overriding his memories with not just his new life, but also his new age. He was constantly gaining and then losing information of his life. By his son disappearing, Tim had caused a paradox, one that the universe was trying to rectify. Tim shuddered as he dropped back into his twenties. Tim grabbed his forehead in worry, well even if he got too young, he'd just become Lizzys kid again right? Tim swung back and looked at Lizzy. She was still laying there peacefully, before a slight spasm cascaded over her body. "Hey that tickles Tim." she sat up and grew confused at what caused it as she noticed Tim wasn't in bed at all with her.
Tim looked back at Lizzy has her long flowing hair receeded a inch, her face starting to grow a spattering of ance across her face as she turned nineteen. Tim's eyes grew wide. Or that could happen, he thought to himself. If Lizzy was getting younger a year every hour, she'd be only five by the time he was a newborn. Tim cursed out for the first time ever. "Fuck." he didn't even know where he learned that word, but it seemed apt. Tim looked back at the clock. 9am. He'd only have till 11pm before they were both left as kids, or worse. But what could he do?
