"I JUST REALLY NEED BOOBS WHICH WOULD GROW MUCH FASTER THAN THOSE!"
As soon as Jason heard the voice he experienced a sudden sensation, something which could only be compared to a shiver running down his spine, if only he had one. Immediately afterwards he felt the soreness present in his body increase slightly. Then go back to how it was before. Then increase again just to ease a second later. It was like a combination of a throbbing and soreness took over his body which didn't feel comfortable at all.
Another thing definitely not helping in feeling any more comfortable was the fact his 'penis' seemed to be getting hard. But Jason wasn't experiencing any of the usual sensation of blood rushing into his organ to have it slowly stand to attention. Instead his appendage seemed to be... tightening. That in turn made it rigid enough to try resisting the fabric in front of him, poking into it and stretching the elastic material. And the weirdest thing about this 'erection' of his was that it wasn't at all sexual in any way. That has never happened to Jason.
"Hey, hey! Calm down Chloe!" the voice of the first girl appeared again. Jason noticed the wall he was attached to stopped moving. "Just take a deep breath, and relax... Go on, breath with me."
The wall behind him started to push into Jason pressing him even tighter against the fabric spread over him. He was sick of the unfamiliar movements and sensations. Whoever was responsible for this better have a good reason to be doing this...
"Also," the girl voice continued. "You might want to fix your shirt. Your... things might have gotten too excited."
It took an immense weight pressing first into his 'penis' and then into the rest of his body for his mind to click. The entire conversation he just heard played back in his mind. He saw the two young girls who walked near him arguing about, well, female puberty. He saw one of them getting upset about being to flat and pleading for faster growing breasts. He saw how getting slightly too excited about the matter made her nipples stiff, something her friend pointed out to her. Finally, the girl covered herself pressing her hands against her chest.
As Jason imagined how the conversation looked from the outside observer he tried to place his own feelings in the context of what was happening. And to his disbelief one answer became as clear in his mind as it was insane.
"Oh fuck." Jason thought. "I am a boob."
