Jeff could feel his heart pounding hard in his chest. He found himself wishing that he hadn't chosen to wait ten for the transformation, because he was feeling nervous and somewhat scared. He found himself wondering if there was a way to cancel the transformation. He'd already backed out once though, and he didn't what to do so again. Jeff sat and waited as the ten minutes passed by so slowly, it felt more like ten years. Eventually though, the ten minutes got down to zero,
Jeff's nerves got worse as there was a knock on his bedroom door. After a couple of seconds, the door opened and Jeff's mom walked in wearing just a white bathrobe. She smiled as she looked at him. Jeff was suddenly struck by thought of how young his mother looked. She was 42, but she could pass for someone at least ten years younger.
"So," she said as she walked over to where Jeff was sat. "I think you know why I'm here".
Jeff swallowed nervously and nodded his head.
"I wish this didn't have to happen", his mom said with a comforting smile. "But you don't have powers like the rest of us, so I'm afraid you're going to have be used, to stop others from taking you as a slave".
Jeff nodded his head again, deciding to play along rather than put up a fight.
"I understand", he replied. "I just wish it didn't have to happen".
"Don't worry", his mom said. I only have to use you for three days, then you will be...marked...for lack of a better word. Nobody will be able to touch you then. But you'll have to be used by us at least once a month from now on. Now, what should I do with you"?
Jeff was taken aback by the question, he assumed that his mom would just come in and turn him into her vagina.
"Erm", he said nervously. "I could become part of you".
"Good idea", his mom replied. "So, which part of me would you like to be".
Jeff suddenly felt quite embarrassed, but he somehow swallowed hid pride and replied;
"I...err...I'd like to be your...vagina".
Jeffs mom looked initially stunned but then she smiled and said;
"Y'know, I actually had that in mind. I don't know why, but I really like the thought of you being between my thighs. You need to take your clothes off".
Jeff hesitated for a few seconds, but then he started to get undressed, feeling increasingly self conscious. Eventually though he was naked and standing before his mom.
"Don't worry, this won't hurt", she said softly. She waved her left hand and Jeff felt an odd tingling in his. The next thing he knew, he was slowly shrinking. He got down to about eight or nine or inches and then the shrinking stopped. He was still feeling incredibly nervous, but not scared anymore. Jeff's mom then walked over to him, and he stood looking up at his mom, who at 5 feet 10 inches, now looked to be about as tall as a nine or ten story building. She unfastened her bathrobe and slipped it off her shoulders, letting it falling to the floor behind her.
Jeff felt a sudden sense of excitement as his crouched down and reached down for him with an enormous right hand. He stood still and allowed her to gently wrap her giant fingers around his torso. She then lifted him off the ground as she stood up and walked to his chair. She then sat down and spread her legs as she made herself comfortable. There was a flash of light and a full length mirror appeared before them.
"Ready"? His mom asked as she slowly licked her lips.
Jeff nodded and after a few seconds of silence replied, "Ready".
He watched in the mirror as his mom spread her outer labia before moving Jeff backwards toward here and pressing his feet against her inner lips. He was belly down and his head was toward her knees. Jeff could feel them, soft, warm and smooth against the soles of his feet. The next thing he knew, His mom pulled him toward her and he felt the lips move around his feet as the disappeared inside her. Jeff heard his mom let out a soft moan as his lower legs disappeared inside his mom's vagina, followed by his upper legs. He could feel his heart pounding hard in his chest now as his hands, arms and lower torso were slid inside her, and then his upper torso too. Eventually, only his head was left outside of her, and he could feel her inner lips gently pressing on his neck whilst the muscles inside her vagina lightly held on to his body.
He could see his mom had her eyes closed. Her breathing was shallow and she had a somewhat contented smile on her face. Suddenly his mom let out a soft groan as he felt a tingling in his feet and lower legs. He felt a strange sensation in them, as though they were spreading and melting, merging with his mom's body. Over the course of the next few minutes, he felt his knees, upper thighs, hands and lower forearms all melt and merge into his mom. For her part, the groans and the look on her face told Jeff that his mom was getting some kind of pleasure from turning him into part of her body. The sensation spread into the rest of his arms and his whole torso now, and then it moved into his neck and head. To his surprise, his hair disappeared, along with his eyes and nose as his mouth twisted into a vertical position and elongated. He wasn't sure how, but he still see perfectly well. At the Same time, his lips both seemed to split and change into each side of his mom's outer and inner labia. He then felt his throat start stretch, and it moved all the way back to where his feet used to be. It seemed that what used to be his stomach and intestines merged with it. His mom let out a loud groan, than gave a satisfied smile as she licked her lips and looked into the mirror.
Jeff also looked into the mirror. He felt stunned. He was also feeling a sense of disbelief and of excitement. There was no trace of him left. When he looked into the mirror, all he could see was his mother's vagina. It some time for his mind to accept that he was looking at his own reflection. Jeff reckoned that it had taken about 15 minutes, but he was now his gorgeous mother's vagina.
"I really enjoyed that", his mom softly. "I hope you're going to be happy down there for the next three days. But understand, to me, you're not a sixteen year old boy anymore, you're my pussy. And that's how you'll be treated. Don't worry though, you'll be well treated. And I'll see you in three days".
Jeff's mom then stood up and retrieved her bathrobe. She put it on, and headed out of his bedroom, presumably to get dressed. Jeff had no idea what his mom had planned for him now that he was her genitals, but for the most part he was looking forward to finding out.
