....you’ve had such an annoying habit of cheating on me, you know?”

“Jess, please. You know I didn’t mean anything by it!”

She giggled. “Oh, I know that! I knew you’d always come back to me. And you did! You can’t resist my beautiful, firm, round breasts, can you? But lots of people didn’t knw. And the things they said about me were so annoying! Some people might have found them insulting, even” She held him more tightly, constraining his breathing.

“Jess .... you’re squeezing me ... too hard. You don’t ... know your own ... strength!”

“Oh but I do!”

Robert didn’t know what to say. He looked up at her, becoming really concerned for the first time. He was now aware that he had no idea what she would do next. His passive, submissive girlfriend suddenly seemed to have a very strong will of her own.

“What was that, Robert? Oh, you’re so CUTE when you’re scared, especially when you’re scared of ME. And I think you would be even cuter and even less likely to cheat on me ever again if you went BACK to the way you were before.”

She held the gun out and adjusted the settings to shrink and weaken, then aimed it at Robert. He squirmed in her arms, trying to get away, but she held him immobilized.

“So are you ready, Robert? Set? Go!”

She fired the gun at him. He immediately began to shrink, his head moving across her breasts and then down her torso until his lips were nearly at the level of her navel. But his muscles were still as large and in fact looked even larger than before on his small frame. He hoped that maybe Jess had made a mistake in the settings. Perhaps after he finished shrinking in size he would get even stronger and could overpower her!

Jess was concerned too. So just to be sure, she gave him an extra dose.

She needn’t have worried. As soon as he stopped losing height, he began losing his new muscle. His arms first became soft and flabby, as the strength drained out of his muscle. Then they begin to get smaller, losing their roundness, their vascularity, and then their size, until his arms were slightly smaller than they had been at the beginning of the evening. His abdomen, although still toned, had a slight pouch, and his legs jiggled just a little bit.

“Hey!” Robert said, protesting. “You’ve just undone a whole year of hard work!”

“Did I?” Jess said. “Oh my. This thing IS so hard to control!”

But as she spoke, the effects of the second dose kicked in.

Robert's remaining muscle began softening. His abs nearly disappeared and his stomach puffed out into a round belly. His legs became as soft as jelly and his arm muscles sagged, drooping down nearly as much as his biceps had previously popped. In the next second, the muscles themselves dissolved, leaving Robert a thin-chested boy-like frame with biceps that barely measured 6" around.

"Jess! Jess!! Look at me! What have you done! Change me back, right away!"
