The next morning your brother, Brady, walk down the stairs in nothing but black boxer briefs, displaying his new older body like it was a new item of clothing. It was only now that you realised how much he had actually changed since the previous day.
His younger body was nowhere to be found under his tan skin that stretched over big pectorals, his shoulder were broad, and his butt was giant under the stretched fabric of his underwear, not to talk about the bulge caused by his clearly massive penis.
Your staring was inturrupted by a shout from your mother
"Brady! I've asked you countless times to put on clothes before you come down for breakfast! Not everyone wants to see your man parts no matter how much you feel the need to show them off!" your mother says, standing in the doorway. "Go and put something on."
Brady sighs, then turns back up the stairs, at which point you appreciate his ass and the way it bounces at each step. After a couple minutes he comes back down wearing jeans and a white t-shirt. He sits next you and you both quickly eat, and he picks up his school bag and walks to the door with a 'Bye Mom', grabs the door handle and turns to you asking 'Do you want to come with me today?'
For a second you're puzzled as to what he means, but quickly understand when you see the keys in his hand and the new car outside.
"Sure", you respond, astonished at how much the world has changed to accomodate your 18 year old brother. As soon as you get into the car Brady turns to you and says
"I know that you changed me. I woke up and heard my door closing and tried to get up but felt really dizzy, and I went to my mirror and saw that I'm fucking hot now. Ryan (your other little brother) wouldn't be u; at 1 am so I know it was you"
"Look Brady, I'm sorry" you begin to respond
"Sorry!? Why the fuck would you be sorry? You just gave me the fucking hottest and most beefed up body ever, and my dick is fucking huge now. I could fuck so many people, and so many people will want to fuck me I'm so hot"
"You're, welcome?" you reply uncertaintly
"But one more thing, how did you do it? How did you make me older and hotter?
