Standing there in only your over-sized t-shirt you pay the man for another roll and add on 2 more, so you could be anywhere from 4 to 24.
You roll them out and count them up, a 6, a 4, a 3, and a 2... woohoo 15, you will at least get a little older.
You feel your body start to tingle again as your 12 year old body goes into a growth spurt. Lifting your shirt slightly, you watch as your balls grow slightly before your pubes start to grow back in... but the hairs are brown, not your normal blond. Your skin tone also looks more tan.
You look up at the carnie and ask "What's happening to me?" in a cracking voice.
The carnie points to a sign and tells ya "Only one prize per person per day. So, if you play again you have to be another person!"
Looking back down again you see your shirt almost fits again, even a little tight in the chest. Your pubes are thicker now, framing a decent now uncut 5 incher. Your legs are much hairier than the last time you were 15, legs strong with big feet on the ends. Your hands are large and strong, looking up your arms you flex your larger biceps. You look across at a mirror and are shocked to see your new face. Your brown hair is short and spiky, your handsome face already has signs of thickening peach fuzz on your upper lip and chin.
Reaching down you pull on your underwear and shorts, which actually fit your new waist. In your wallet, your license is gone, replaced with a high school student ID. Your name is Mike now!
You think and try to decide if you want to just stay with this body or try again for something older. But smiling at your hot self in the mirror you think about going back to high school.
