You grab the condom that is closest to you and take off your clothes. You then take off your whte briefs to reveal your young cock. You're just embarassed lookin at it. Slowly you grab the condom and place it on your dick quite easily.
After you have the condom on you begin to jerk off hoping to change back. As you furiously jerk it you realize you're gettig taller. Except not much.
You only grow a few inches before stopping at 5' 11" which is pretty good but not your original height. "I guess it didn't work" you begin to say before realizing you haven't come. But the transformation wasn't over yet.
You continhe to jerk off as your body begins to grow once more but horizontally. You gain weight as two large moobs and an overhanging gut begin to become pronouce on your body. Your hair turns a dark shade of brown as stubble erupts over your face, and your hirtsue on your arms, and legs. You begin to become wider and heavier as you come into the condom. You take it off your much longer and wider cock.
Although not as big as your Dad's cock, it was a bit bigger than your original one. You're surprised to see a crazy amount of brown pubes surrounding your new dick and balls and decide you have to look in a mirror. Your room had changed back to a guest room but with a bathroom this time.
You step inside and nearly pass out from the shock of your new form. You gasp to see a chubby teenager staring back at you. You would have to guess 17 years old. Your hair and eyes were now a dark shade of brown along wih your body hair. Your jaw had become more pronounced but hidden under you new double chin and fat. Your cheeks pratically bulged aloong with your stomach from your new weight. You find an arrary of chest hair cover your new moobs and gut attempt to peek at your dick but are stopped by your huge stomach. You cradle your belly and watch it jiggle in the mirror from the impact of your movement.
You shake your head in disbelief. "Why am I now some chubby kid?" And who am I now?" You begin to think and rush to your phone on the bed but as you race there the door begins to open. "Hey Marty are you done yet?" A familar voice says.
You then watch as your older brother Mark, enters. "Woah dude! I said it was okay to put on your uniform but I thought you were already done" he says trying to shield you from his view.
You look at Mark in disbelief. "Wait! Who am I and what am I doing in here?" You ask him. "Are you joking Marty?" Mark says beginning to laugh."Remember we were supposed to grab our wrestling gear before practice. But you wanted to get dressed first" you then find your previous clothes transformed into a singlet and a jockstrap along with some gear.
Mark then steps out of the room "Okay come out when you're done" he says and closes the door. You then look and the wrestling uniform and unwillingly put it on. Your jockstrap feels nostalgic from your previous body but the uniform is incredbikly tight. "Must be all this extra weight" you say as you struggle to put it on and as you finish you realize the condoms are missing."What the... where are they?" You think before spotting a duffel bag cotaining a pair of clothes you assumed you had worn beforehand and the box of condoms. Once again they had magically dissapeared when needed.
You grab the bag and your phone and walk out the guest room to see Mark ready. "Hurry before coach has our ass doing extra miles" he says as you follow him outside. You walk to his car and hop into the passanger seet as he places his own bag in the back seat. "So we're both on the wrestling team?" You ask him. "Nows not the time for jokes! We better hurry and get to school" and drives. You then take out your phone and go through your pictures to see photos of you and Mark hanging out at the movies and at some games. It seemed you had turned into, a kid named Marty, the best friend to Mark. You sigh the condoms had not worked again and this time you had wrestling practice.
