"Jon has a vagina instead of a penis. Jon has modest sized breasts for a girl his age. Jon wears female clothes but in his usual style."
She left Jon aware of the changes and left it so to everyone else this was the way things always were.
In the early hours of the morning Jon's body started to change. He slept though the changes but if he had been awake he would have felt his chest expanding as he grew a pair of B-cup breasts. His nipples grew much bigger and wider and stood out. The vagina he had gained yesterday remained unchanged as did the panties he had gone to bed in. The t shirt he was wearing changed slightly. The material becoming a little bit softer and the sleeves shortening up towards his shoulders. The bottom of the shirt rose up a bit too, exposing a small strip of his stomach and doing nothing to cover his pantied crotch.
Jon had been sleeping on his front but this became uncomfortable as his breasts filled out. In his sleep he had turned over to his back, oblivious to the changes.
Jon remained that way until his alarm went off, waking him up. He slowly turned towards his locker but felt the strange movement as his chest jiggled about under his t shirt. He quickly woke up when he felt the alien sensation. He quickly turned off his alarm and dripped his phone. He lay back on his bed and stared down at his chest. The design of his t shirt was the same but the lower neckline exposed more of his chest. He pulled the t shirt away from himself and stared down in awe. He saw two smooth, soft breasts on his chest with two dark pink nipples taking pride of place.
"Am I slowly turning into a girl?" Jon wondered aloud. He could tell he still had a vagina without having to explore his lower body. Any other time he had seen a pair of breast this close up he would have been rock hard but just like yesterday Jon's crotch stayed neatly tucked away in his panties. He brought one hand up to cup each of his breasts. As he rubbed them both he felt his nipples reacting, growing hard and poking into his palms.
He quickly pulled his hands away when his mom popped her head in his door. "Oh good, you're awake. Cmon honey, up and at it now. Breakfast is nearly ready. Get dressed and I'll see you downstairs." Mom said before closing the door again.
Jon looked down at his chest and thought to himself that there was no way she didn't notice his breasts but she didn't seem to react. And after yesterday he was fairly sure nobody would think it any stranger that he had breasts than him having a vagina. He hoped he was still considered a boy as he didn't feel like a girl despite the breasts sticking out on his chest and the lack of anything sticking out between his legs.
Jon accepted that staying in his room wasn't an option so he got out of bed and went to pick an outfit for the day. The jiggle of his breasts was very distracting for him so he held them down with one forearm when he opened his drawers and picked out a pair of jeans and a t shirt. He selected a clean pair of panties and socks and proceeded to get dressed.
He removed the t shirt he had slept in, sighing as the material brushed off his nipples. He pulled on the fresh t shirt, noticing it too was cut slightly differently and showed a bit more cleavage than he liked. His loose breasts were driving him a bit crazy as he bent over to change his panties. Next he pulled on his jeans. It was only when he buttoned them up that he noticed they had changed a little bit. They felt a bit lighter than he remembered and they hugged his legs much tighter than he was used to. The front of the jeans was also cut different, lying very smoothly against his crotch, making it very obvious that he wasn't built like every other boy. Despite all these changes worrying Jon a bit he kept telling himself that no one was likely to find anything unusual about it which gave him some strength to face the world.
With his socks and sneakers on, Jon started to bound down the stairs. His bouncing boobs made him quickly adjust and slowdown his pace. Having boobs seemed way more noticeable to him than having a vagina. When dressed his vagina was out of sight, out of mind but these boobs were there, front and centre, reminding him of their presence with every movement he made. As Jon entered the kitchen, his mother turned to look at him and said, "Jon honey. How many times do I have to tell you, you can't leave the house without a bra. I know you don't like wearing them but you don't want your boobs to sag, do you honey? No girl will want to date a boy with saggy boobs. Please go back upstairs and dress properly. "
