heights with his sister.

    by: Saracen1187 Author IconMail Icon
He of course thought about swapping genitals with his sister, or maybe borrowing her tits for a while, but instead he wanted to experience being shorter. And at just 5'2", his sister was perfect to swap with. Her heels added three inches to her height, but even with her boots on she was still five inches shorter than David was. While rubbing his soft, feminine hands together, David focused on Jamie before he sat down and immediately felt himself shrinking down. The inches dropped away as he dwindled down his sister's paltry 5'2", meanwhile Jamie (who was still sat down) enjoyed a growth spurt of eight inches.

When she got up to put her empty soda can in the trash, David had to look up at his sister, who now stood 6'1" in her high heeled boots. And still sporting his larger hands on the ends of her arms, David was beginning to think she looked even better. "What are you looking at bro?" Jamie chuckled, putting her hands on her hips.

"Just wondering how you ended up so much taller than me. I mean, I'm a guy after all." He said, wondering what Jamie's reply would be.

"Dunno, just luck I guess." Jamie shrugged, peering down at herself. "Probably same reason I ended up with bigger hands than your average girl I guess. We can't choose how we're born." She added.

No. But I can alter things after we're born now. David smirked to himself, as he tried to get used to everything looking so much bigger to him. Also amazing to him was the fact that his clothes had altered to fit his new petite height. Going one step further, David concentrated on Jamie again, and this time her body's muscles started swelling, not immensely, just to those of your average 20-year old male's. David's muscles meanwhile dissipated as he took on his sister's physique. Now he was shorter and weaker than he had been, while his sister towered over him and was much stronger than he was. The whole thing was really turning him on, and he wondered whether he should keep swapping with Jamie or reign himself in.

This was his sister after all, and even though she was unaware of her swaps, a tiny part of him felt guilty about doing this to her. His cock certainly seemed to like it though, since it was that hard it was beginning to ache somewhat.
