She'd become shockingly gorgeous, and all her boyfriend had noticed was that there was something slightly different about her. Gripping the ring, she silently wished he would be more of a man and grow up!
He stood there, looking at her, then she noticed his five-o'clock shadow becoming darker as his muscles swelled and he began to get taller and taller. And taller, while his crotch swelled obscenely. He looked down at her, oblivious, asking in a voice a couple octaves deeper, "Did you do something with your hair?"
Something was certainly going on with his hair: it was sprouting all over his body, thick as a pelt as he passed seven feet tall and kept going, his already enormous crotch swelling further, and she could see his cock in one pant leg going down past his knee!
"Or did you get new lipstick?" he rumbled and she wished that whatever it is she was doing to him would stop.
It did, but her boyfriend was now standing there, an eight-foot-tall hair-covered hypermasculine giant.
She rubbed the ring. "Uh, no. Just some new accessories." She looked at him, realizing that only the wearer of the ring noticed the changes made with it. Everyone else--her boyfriend, the gorgeous woman she'd turned into a gorgeous man--thought that however the world was was the way it had always been.
Thinking, she silently wished that her boyfriend were as attractive as she was, and she watched as his shoulders broadened slightly, his chin became a little more defined, and his thick body hair became neat and gleaming. There were other subtle changes, but otherwise he looked the same as he had, or at least as she'd just made him with her wish for him to "grow up and be more of a man."
