Josh was being homeschooled by Martha for the past years. Mostly this was Martha's choice but Josh had agreed with it.
Josh one night about two years later was having a dream of having sex with a younger version of Martha. He ejaculated inside her and ... then he woke up. His face covered with his own cum, along with everything around his cock head. His cock was pointed straight up, just a couple inches from the roof. His penis had grown over the past two years reaching 58 inches in length when hard and almost 34 inches while soft. He was only just at the start of puberty but he was already beyond massive. He instinctively started rubbing his cock. He rubbed both his hands around his cock up and down as much as he could. He started moaning a little as his balls tensed. He then came over himself again almost shooting cum everywhere. He wiped the cum from his face as he got out of bed and supported his heavy semi-soft dick with his free hand. He wiped his hands on dirty laundry and then cleaned his room as best as he could .
In the following evening Martha had already found out. She was a little annoyed at the prospect of not being to fuck him safely anymore while they were alone at home but still fucked him whenever she could, which was practically daily. Josh started watching porn on the internet. He was mostly amazed how small other men where but still fapped to it. The next morning he stood in front of the mirror looking at his own cock. He got hard just thinking about last night. He looked at his hard cock and studied it. His cock was massively long and far thicker than practically all guys he had seen. Of course his body was far from that of a man still. He looked at his balls and remembered the proportions of the men in the porn video´s. His balls were pretty big for his body, the size of beach balls. In fact they where far bigger than the men in the videos it seemed.
Puberty hit him hard the over the year. His cock gained 12 more inches, he got taller, almost as tall as Martha and his musculature was visible beneath his skin now. No matter how much he ate it seemed to go to his cock and his height. Having sex with Martha was getting harder however. His cock seemed to get harder as it got longer and though it mostly gained length it seemed to get a little thicker as well making it harder to put in. One night Martha couldn't get it in and got him off with her breasts. The next night she got it in and said that it hurt. She pulled out quick and left him hanging. Josh begged her to get him off. Josh noticed while jerking off that when ejaculating his semen seemed to explode out of his penis. It coated everything around him with cum. However the feeling of the cum made him cum multiple times after one another which was fine by him.
Josh looked up a lot of things on the internet. He had learned how massive he was. He had learned that to his surprise he was a little on the short size for guys his age. He got to know a girl on the web that seemed very nice. He wondered about inviting her over after she typed about being interested in having sex.
