He Did Not Read The Instructions

As Sarah groaned, her body began to slowly morph and change. Her once luscious, beautiful, sexy flowing hair shrunk, and her frame began to expand, somewhat tearing her shirt and joggers, exposing her heaving tan, ample bosom, with sweat pouring down her chest. She began to scream, almost orgasmically. Her once full, sultry lips became more masculine, as did the rest of her face. Her once beautiful, italian, sexy neckline became more masculine with her frame. Her hips became more streamlined and straight, less curvy.

Her toned body became more manly, getting the beginnings of a six pack. Her perfect, round, tan, and pert C - Cup breasts began to shrink, and shrink… until they were no more. And for the final touch, a very obvious bulge started to appear in her light jogger shorts.

With changes happening all at once, Chris watched in horror as his beautiful fiancee became.. Something else.

Sarah was becoming a man, but not just any man. She was becoming as tall as John & Chris, gaining muscle, and her cock did not stop growing. In horror, John ran away, to read the box to see how he messed up. In horror, John read the following:

“Do not mix with alcohol. Will produce extreme amounts of estrogen in men & testosterone in women.”

And just like that, Sarah was no more. She became a manly figure, resembling the likes of John, albeit a little more muscly, and with a raging boner twice the size of John’s. In more shock than anger, she ran to the restroom, hiding her exposed crotch in embarrassment.

In horror, Chris ran out of the house, and he would never be seen or heard from again.

John was angry and cursing to himself as chaos rained all around. He had failed to do it. He had failed to gain the ultimate revenge. Instead, he just gained a bigger older brother, and was in the same situation as before. Time will tell, though, how his sister’s life will be affected.
