getting acclimated to life with a sister

The next few days were both titillating and frustrating for Tom. Sarah paraded around the house barely dressed, completely at ease with herself and no discomfort around Tom. He couldn't hide his arousal from her given how affectionate and physical she was - always hugging or touching him in an affectionate (though non-sexual) manner. His reactions amused her; she took joy in seeing him so worked up, but she wasn't cruel or manipulative. It was like she was had a free and wild spirit - almost an innocence - that those things didn't bother her.

It was a struggle to keep up with her - both physically and mentally. She was so full of life and energy, constantly on the move. Even when spending a "relaxing" evening at home with Tom, she would talk about everything in both their lives and reminisce about their childhoods. The latter was a continual headache for Tom. He of course had no memories of her to draw on. Their past as siblings was a complete blank to him, and he did a very poor job of covering. Sarah began to express concern about his apparent memory problems.

He considered using the coin change her again, but he found that he really liked this Sarah and didn't want to risk changing her personality. Finally he was struck by an idea. Perhaps he could use the coin to indirectly change himself THROUGH Sarah. He thought it was a long shot but decided to give it a try, so he wished that Sarah had an unusual ability that affected only him - that whenever she brought up something about his past, she would cause him to gain actual memories of the event. Amazingly it seemed to work. The next time she brought up one of her stories - this time how he had first taught her how to swim - images instantly popped into his mind of himself and a young Sarah in the pool. Over several days of this he began to accumulate a fair 'recollection' of their lives.

She even convinced him to go out dancing with her. He was very ****, never having been into that kind of nightlife and also worried about publically showing his obvious interest in his own sister. But Sarah was very convincing, pleading that she was all alone since she moved here and wasn't ready to date yet. "I don't want any more creeps," she stated firmly, "and I don't feel up to sorting through all the jerks I'll attract there to hopefully find someone decent." She snuggled up against him and batted her eyes. "So I need my big brother as my chaperone," she begged in a exaggerated voice.

Of course Tom gave in. He found himself more and more unable to tell her no when she wanted something. The more time he spent with her, the more affection he felt - and attraction, which caused him an unexpected feeling of shame. At the same time, he had greater difficulty mentally matching this woman with 'his' Sarah. With the new memories he was developing, he was starting to think of her as an entirely different person.
