Yes!

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.

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

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.

And just like that, Sarah was no more. She became a manly figure, resembling the likes of John, with a raging boner. In more shock than embarrassment, she ran to the restroom, hiding her exposed crotch, with a peak of her new attachment showing. If there was one thing to be happy about, at least it seems her ample breasts have turned into a big cock, as most of the guys in the family have.

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

John smiled to himself as chaos rained all around. He had done it. He had gained the ultimate revenge.
