You look over the options. The reflection on the screen looks normal, just like any other mirror or camera. What was so special about this place? You decide to give it a shot and you choose the build option, which displays more options below it. It listed your current build as a lean average, and it showed a height and weight. You notice a black square on the floor and you step off of it. Your stats dissappear. Clever, makes a person think this thing can somehow tell what you weigh just by stepping in. You step back on and look at the info. 160lbs, 5'11. It has a bodyfat and muscle percentage, but you don't really care.
You see a choice listing under the build. You scroll through and see lean, fat, muscle, bulk. For kicks, you click fat. Now the weight begins flashing, saying 160, there's an + and - choice. You click the +, which seems to make the number go up in 10lb intervals. You click till it says 400. It states that this body would make you into a hairy caucasian guy, low intelligence, underendowed with a personality of crude and loud. That was just a bit too weird, so you clicked the hair options and found a hairiness level, which you set to no change along with hair color, personality to no change, and appearance to no change save for weight options. You chose the unusual characteristics and saw your penis size listed as underendowed with a size of 2 inches listed.
"Is this thing gonna generate a nude picture of me or something? Kind of weird if they allow kids in here... well, I don't want to be underendowed even in a photo." So you click the slider and put it up to average, then well endowed, then overendowed. It lists your new length as 11 inches. You chuckle to yourself. "I guess I just click enter now..." You click it and wait for a photo flash of some sort. Nothing happens. Then the screen refreshes and you see a picture of a fat version of you showing on the side. You laugh "Pretty good, but where does it print?" Then you feel a tingle. It starts at your bellybutton, then moves across your whole body. You shake your head when you get a bit dizzy, but you begin to fatten. Your lean body begins to fill out. At first it looks like a freshman 15 and you don't notice, but as your belly grows, your shirt conforms around it and you begin to notice.
You look down and your eyes widen as your body inflates with plump, bouncy fat. You look at the screen and see yourself changing there, slowly starting to look like your photo. Your clothes tighten around your growing frame as your small pecs become boobs, your flat belly plumps out round and heavy, your hips widen and your ass rounds out. You thicken all over. Your jeans feel tight in the crotch now... oh no! You made your cock huge! You turn to the side and see the bulge in your pants almost matching your bulging belly. Your jeans rip apart over your fat ass, which relieves you slightly up front, especially as the button bursts from the waist. Your thighs rip open the painted on denim as your body keeps growing. Your widening torso rips your shirt on the back, and the seams on the sides rip as your belly grows out bigger.
You notice that the changing room is getting pretty small.... Your belly pushes up against one wall while your ass pushes up against the other. You feel the swelling slowing down, just as the zipper on the front of your pants pops open, showing an intensely tight breifs. "Oh, man... that was insane!" You look yourself up and down. "I can't stay this way." You go to change yourself again, but the machine turns off and displays a message to you.
"For safety reasons, the changing booth can change an individual once a day. More changes can cause molecular instabilities which could cause you to stop existing. Please try again tomorrow!" You panic slightly, you're going to be stuck like this for an entire day!? The door opens behind you and you are forced to walk out when a loud buzzer goes off. You can barely squeeze through the door now. You take a robe on the way out to cover your ridiculous bulge in your pants, not to mention your now substantial body. You waddle around the park, worried about going home. You need to rest a few times, your big body is a bit hard to get around. You weigh your options.
You can come back tomorrow, or find something at the park to help you change back.
