Maybe try out some piercings on yourself?

You've always had a small kink for piercings, but you've been too big of a coward to get any. If this thing works that's a good enough start

You have finished your food and excuse yourself for a trip to the bathrooms. You lock yourself in one of the two stalls available, the place currently deserted. A rather large percentage of your fellow male students would just go for the bathroom during classes to waste time instead of during lunch break.

You pull out your phone and turn on the front facing camera to have a look at yourself. 'I wish I had ear piercings,' you verbalize in your head and suddenly you find yourself with a pair of simple studs in his earlobes.

"What the fuck..." You whisper to yourself as you feel the studs with a pair of fingers. 'I wish for an eyebrow piercing," you verbalize in your head again, and sure enough, suddenly you find yourself with one embedded in your eyebrow. "What the fuck," you repeat and start pondering what else to do.

You've always been slightly out of shape. You're far from fat, but you've never had any muscle tone, let alone a six-pack. 'I wish I had perfect metabolism, that I am in good physical condition and just the necessary amount of fat.' You feel a oomph go through your body as you feel thinner and lighter.

You pull up your shirt and find yourself the proud owner of a lithe torso with hints of muscle. Not exactly macho, you're personally no fan of burly alpha male anatomy to begin with, so you're not unhappy about that.

If anything, you get a bit curious about what other things you might test out as you look down on your chest. 'I wish I had pierced nipples that are so sensitive they can make me orgasm,' you verbalize. Then you blink and blush as you see what just happened.

Your nipples perked up and inflated up to the width and height of the tip of your ring finger, and tiny mounds of fat seem to have gathered underneath, making the flesh of your pecs soft, round and pliable. The appearance of the bar bells through them were the least weird part about the change now. You cup your chest and pinch the bar bells with a pair of fingers and give them a twist.

You gasp as the sensation of having what feels like like tiny dicks on your chest sending shocks of pleasure through your chest into your body. Instantly your skin blushes and your heart begins pumping blood through your veins. Not to mention your dick growing hard in your trousers. You release the pinch on the metal and get a moment of relief.

To your confusion, however, your body apparently has no brakes now. Your nipples are hardening around the bar bells and your dick is throbbing aggressively in your underwear. In fact, your entire pelvis seems to be throbbing heavier with every pulse of your heart. "Shit," you whisper to yourself as you unzip your pants leaving your dick bobbing in the cold air.

It doesn't help at all. Your body is on fire and it's pulling you under. You take long breaths trying to control yourself, but you feel the barbells rising off your aerolas as your nipples perk up. You give in and carefully poke your index fingers into both nipples. As the sensitive and hardened flesh yields, small bursts of pleasure rewards your body and your legs shudder. You groan as you let your fingers slowly circle, tugging at the bells when they pass by.

Within half a minute you feel your dick is starting to ejaculate. 'Oh shit, don't cum' you think strongly to yourself and try to hold back as you grab hold of your dick to avoid shooting a stream at the stall door. Instead of a shot of grey white fluid shooting into your arm, drops of clear fluid gently pop out with every delightful throb of your dick and nipples. What the hell?

You remove your hand and let the pre-cum like fluid slide down along your shaft, gathering between your legs. You'd be confused if it didn't feel so good, your hands both back at teasing your nipples, lubricated by your dick's clear pre cum fluids. You're pretty sure you're currently in an orgasm you've never felt before. One started by your new chest assets.

You rub your nipples for another minute and suddenly the pleasure ramps up again, leaving you shuddering twice as hard and finally unable to control yourself, moaning loudly as you ride off a double orgasm. Your dick momentarily trickling constantly with with the clear, slippery fluid, spilling onto the toilet seat lid you're sitting on and completely covering your dick and nut sack.

But at the very least you haven't sprayed down the walls. As soon as you begin coming down from the best orgasm of your life, you pull out some paper and start dabbing your crotch and toilet seat to clean up the mess.

You roll your eyes as you remember that you have fucking wishing powers. 'I wish the stall and my outfit was clean and with nothing out of the ordinary,' you mentally declare. With the next breath you find yourself smelling and feeling as if you've come out of the shower less than an hour ago. With a fresh set of clothes.

You smile, stand up and give the place a last look and go outside to wash your hands.

You realize It's the first time you've seen yourself in a real mirror. You certainly are thinner and even your outfit seems to have changed to adapt to your new body. The shirt is tight and your nipple piercings might flare through if you get aroused again, but you think you got four to six hours before your body needs another jerkoff. You tilt your slightly flared hips to pose for yourself and fluff your hair forward so it covers your chest slightly.

You pause for a second to ponder if you used to have this long hair ten minutes ago. You honestly can't say and you specifically can't recall wishing for it. Then again, you can't remember wishing for your cum to be clear and not the final part of your orgasms either. Maybe that was a side effect of having nipples that you could get orgasms from? You've read that prostate masturbation made your dick do weird things, so maybe nipple orgasms did the same.
