Trent and Flint don't get along very well. Despite they're brothers, the age gap between them has been a strong barrier that just got worse when they began to get different hobbies and interests. Trent is 17 years old and a gym rat, at his young age he's strong enough to compete against several men twice his age in wrestling, football, and baseball. He also enjoys to show his brawn body in the beach, so he keeps it shaved and goes to sunbath every weekend with his friends.
Flint is quite different, he isn't a nerd or an outcast, but compared to his brother, he's very average. He isn't fat nor skinny, and Trent use to tell him he has potential to get a good body like him, but Flint is not interested at all. He likes to stay at home, play some videogames, watching movies, hanging out with his friends and playing basketball, casually, of course. Despite he's 10 years old, some people use to think he's younger because he's not very tall and, compared to his brother, he looks even smaller.
Flint is the kind of guy that everybody likes, everybody except his brother, who usually is bullying him at home, in family meetings and basically any occasion he can. Until Trent goes to college, they're going to be sharing a bedroom where Flint is usually victim of several pranks, insults and lame jokes about his punny and small body. He had learned to deal with that, which infuriates Trent even more cause he thinks his efforts are not enough.
One day, while Trent was hanging out with his girlfriend at the beach, they saw Flint and his friends collecting sand and some seashells. They're doing a school project about oceans, so they're planning to use those things to make it look good. Trent was trying to ignore his brother, but when a big wave suddenly pulled Flint to the sea, his girlfriend started insisting that he should help his little brother. He didn't want to, but he can't ignore his girlfriend if he wanted some action later, so he immediately ran to save Flint.
That night, after having some good sex with his girlfriend, she began to remember the incident at the beach. She felt proud of her strong boyfriend and she made some comments about the distant relationship between Trent and Flint. He told her he had tried to push Flint to go to the gym with him or joining a football team, but Flint keeps ignoring it. So, she told him she had heard about the puberthere and how it can increases someone's maturity, she also told him her uncle knows a guy who has used it on his step son, so he can turn him into a woman his age and marry her.
Trent didn't understand why his girlfriend was talking about that until she suggested she can get that puberthere and Trent can use it on Flint, so he can be as old as him, maybe that will help to their relationship and Flint could get more interested in Trent's likes. He told her that wasn't a very bad idea, and he also was curious if Flint will get some more development on his body after puberty just like it happened to him.
After a few months, Trent has almost forgotten about the puberthere when a day, his girlfriend arrived at his home with the device. She told him it was harder than she expected to get it, because the guy had moved out to another country with his new wife, but he had left the puberthere with some relatives that thought it was just trash. He wasn't sure if he still wanted to use it on his brother, because their relationship started to get a little bit better when Flint began to play football with his friends and watch some games with his older brother. However, he didn't want to disappoint his girlfriend so he took the puberthere.
He told her he would use it when his parents weren't around, so he won't get in troubles. She agreed and left after having sex. That night Trent was thinking about the puberthere in his room when he got a call from his coach telling him that a lineman had broken his arm and can't play in tomorrow's game. He told Trent they don't have any other player to replace him, so he was asking for Trent's help to find another guy. Trent immediately began to call to his friends but none of them was available for tomorrow's game. He was getting desperate when Flint came in.
He knew it could be a bad idea, but maybe Flint and the puberthere could be the solution to his problem. Now, he only needs to decide if he's going to ask Flint for his consent or not.
