Then, a female voice came from the door that Megan did'nt closed:
"Hello? Megan, Will? are you there?"
A young woman entered in the room, wearing a pink shirt and a frilly skirt above her knees, and her blond curly hair flowed over her shoulders.
She stopped, looking puzzled at the two naked men sitting on the floor.
"What's happening here? Who are you, and where are Megan and Will?" she asked.
"Sara, come close. Did'nt you recognized me?" Asked the man that was Megan some moments before.
The girl approached to the ex-woman, looking astonished at her body, then at her eyes. "M-Megan!? It's you?? But... but... what happened to you? This is impossible!!!"
"I'll show you, and this is absolutely possible!" Said Megan, then suddenly grabbed her head forcing her friend on her knees and then to take his cock on her mouth.
"Nooo wha.. mmmph!" Cried the girl before her mouth was filled by the big cock of her ex female friend.
While the TV showed again the man giving a blow-job at the other one, Megan started pumping on Lisa's mouth and reached her first male orgasm. Then released her friend, who collapsed on the ground while her transformation started.
The first sign was a on-growing bulge under her skirt, tenting the fabric of her pants that suddenly ripped, so the cock can spread his erection on the air. Her legs opened gained more definition and muscular mass, and so her arms while she began to stroke her new member. Theo, her shoulders expanded while her boobs receeded in a quickly toned chest, rearranging into huge pecs. Her shirt ripped, so Megan could see her nude chest, covering with dense dark hair coming from the crotch area. The same dark hair spread suddenly across her legs and arms, while her facial features rearranged into a male shape, and on her harder jawline a thick stubble spread across. She complete her transformation just at the moment that her cock reached the orgasm, so she moaned loud in her new baritone voice.
