Pete had first woken earlier, hearing the chatter coming from his twin sisters as they headed downstairs with Biff. They sounded like they were in a good mood and were talking excitedly about getting to watch some cartoons. He had drifted back to sleep but a while later he awoke to a notification on his phone which he had kept charging on his bedside locker. He turned to reach for it but stopped dead in his tracks when he felt movement on his chest. His arm was pressing against something squishy and he had a fair idea of what it was without looking.
Pulling up his quilt to have a look, Pete was amazed to see that his chest had developed while he slept. He no longer had the flat boys chest that he had grown up with. He was now the proud owner of a pair of breasts, fairly large ones in his opinion but then he didn't really have that much experience with them. Reaching up with both hands Pete gave them a squeeze through the night dress that he was wearing, loving the new feelings. He rubbed them all over and shook his shoulders a bit to feel them jiggle. He felt a stirring in his pants and was relieved to feel that he still had his penis which was now as awake as the rest of him and still sporting his morning wood which he had woken up with every morning of his adolescent life.
He reached one hand down and rubbed his penis through his panties and continued to fondle one of his new breasts. He felt his nipples respond in a similar fashion to his penis, becoming stiff and hard and starting to press through the soft material of his nightie.
Before getting too carried away, Pete removed his hand from his panties and climbed out of bed. He ran to the mirror, noting how his chest bounced with every step. The sight in the mirror brought a smile to his face. There he was, standing in his nightie with his penis creating a tent in the front of his panties and his chest filling out the front of his top. The neckline was lower than he was used to and there was even a hint of cleavage showing too.
"How did this happen? " Pete wondered out loud, then he gasped at his voice. It sounded softer and a bit higher than he was used to. Testing it out again he put his hand to his throat and had to admit it was a pleasant sounding voice.
Remembering the notification sound that had woken him up Pete dashed back across his room and grabbed his phone. The notification was a message from Femcorp explaining how using some nano-tech that he didn't even know existed they had altered his body to help him along in the experiment. Along with the breasts, which were a 32C according to the information on his phone, and his altered voice his hips were now a little bit wider and his butt was a little bit bigger. He hadn't noticed the hips or butt but pacing around the room now that he was aware of it he definitely felt a little wiggle in his walk.
Excited to go and share his changes with his family Pete put his phone down and left his room. Biff was in the kitchen so Pete hurried downstairs to show him the changes. His breasts bounced on every step of the stairs so Pete had to hold them with one arm while the other just kind of floated in the air. His hips swayed and his butt bounced a little bit on each step too.
