The next morning, Edwin woke up a little bit weird, just a little so he didn't care too much about it. He went to the bathroom, brushed his teeth and cleaned his face.
Then, he decided to watch some TV. For some reason that day he was more interested in watching cartoons than his usual teenage sitcoms. He stayed there for a while until he felt hungry, so he took the phone, called to room service and asked for a milkshake and a sandwich.
Just a few minutes later, he heard the door knocking. He was amazed of how fast was the service but when he opened the door, his sister Dawn came in.
"Hi Ed! How are you doing until now?" She said as she took a seat on the couch. "I'd had a lot of fun last night! I've been a cat, a seagull, a snake and a spider."
"What are you talking about, Dawn?" Edwin replied because he didn't understand what she meant to.
"My transformations! I been using my room changing properties to become different animals the whole night." Dawn replied. "Didn't you use yours?"
"Oh damn! I was so tired that I fell asleep as soon as I arrived here. I completely forgot about it!" Edwin said.
Dawn smiled at her brother as she took a tablet on a shelf near the front door.
"On this tablet you can write your change and how long you want it will last." She started to scroll down through the information. "It says that you changed into a 14 years old boy since last night but you didn't establish the duration."
"14? That explains why I wanted to watch cartoons this morning." Edwin smiled a little. "I don't remember I wrote that thing, maybe I was thinking about you when I did it."
"Maybe, but that means that for now we're twins!" Dawn widely smiled at her brother.
"Yeah, but I don't think it'll last too much." Edwin said. "I didn't come here just to be 2 years younger."
"I can help you with that." Dawn grinned as she started to write something on the tablet.
"Wait, Dawn!" Edwin tried to stop her but when he took the tablet from her, she had already finished. "What did you wrote?"
"I was thinking about the handsome guys in the superhero movies, so I turned you into that age." Dawn grinned. "I think 30 is a good age to be a hunk, don't you think so?"
Edwin was going to say something to his sister but he didn't because he was already feeling his growing up. As he was wearing shorts, the change on his legs were the first ones to be noticeable. They grew a foot longer and swelled with muscles, especially on his thighs that made his once baggy shorts into skin-tight ones. Of course, a thick layer of hair sprouted all over them until they looked completely manly and sexy.
Edwin was so focused on his legs that he didn't see that his feet had already changed too. Luckily for him, he wasn't wearing any shoes because his former size 7 feet had lengthened into an outstanding size 14 with long manly toes and, of course, a subtle line of hair on top.
"Dawn!! what you have done!" Edwin shouted at his sister in a noticeable deepening voice as he felt his body expanding everywhere. His small preteen clothes wouldn't last too long before they start to rip off.
He put his hands on his crotch as he felt his growing and maturing. Going from a 3 inches boyhood to an impressive 7 inches soft dick. There wasn't enough space in his boxers for that thing, even less when his balls starte to swell as well. It was a mix of pain and ecstasy to feel his balls thickening and filling out with fresh manmilk. Obviously, they were churning so much that Edwin couldn't avoid but groan at the feeling.
His shorts' seams didn't last any longer and they fell down exposing Edwin's new manhood to his sister who wasn't too surprised of what she was seeing. However, Edwin immediately covered his nudity, ashamed of being so exposed.
Dawn noticed then that his brother's arms had swelled with a lot of muscles, giving him a look similar to those Hollywood actors that played superheroes roles. It's not too necessary to mention that Edwin's chest and torso had gotten his own development. His shirt was so tight now that a few holes had appeared on it showing some of Edwin's new muscles and hair. His pecs were like bricks, solid but juicy. His abs looked like a washboard, well, if you ignore the hair that covered them and guided to a prominent and definitively hirsute crotch.
Last but not least, Edwin's neck got thicker. His voice sounded nothing like a moment ago. His jaw got chiseled and square covered by a thick beard trimmed to don't be too long. His nose grew a little bit and his former teenage haircut turned into a buzz cut.
The 14 years old kid has left and a hunky 30 years old man has taken his place. Unfortunately, it wasn't that cool for Edwin who now was naked in front of his sister.
"You know. It's the first time I see you naked since we're toddlers." Dawn giggled. "I never thought that your little weenie would become that big!... And hairy..."
"Dawn, could you give me some privacy? I don't feel comfortable being naked in front of you, especially being this old." Edwin sheepishly said.
"Ok ok, I'll give you some space. In fact, I'll go to buy you some clothes. I don't think any of your clothes will fit you now." She stared at her hunky naked brother one last time before she left.
"Woah, finally!" Edwin lay down on the carpet taking his hands off his crotch. A huge erection jumped up covered in glossy precum. The thick mushroomy tip was still leaking some drops on the bush of hair that surrounded his manhood now. "I need to do this so bad!" He took his shaft and started to masturbate. At first he was doing it slowly and carefully, however as his heat was growing he was becoming more and more rude and intense. He can't avoid to let out several moans and grunts the whole time. His new muscles expelling tons of sweat that quickly full his room with a manly musk.
"Hey, I forgot to ask you if you want boxers or briefs." Dawn said as she entered back to the room, just in time to see her brother bursting out and shooting a big load of cum all over him.
"FUCK! DAWN!! GET OUT!!" Edwin yelled at her as she left the room with a wide grin on her face.
