A Snow Elf's Guide to Magic

The package had arrived ahead of schedule, a useless nicknack and a book. More precisely, a glowing blue gem and a book titled "The Snow Elf's Guide to Magic" by Yukihana Lamy. You never believed in these things, however, you did love being chuuni from time to time. It was fun to just simply play pretend every once and a while. Opening the box, you removed the thick blue-green book and the crystal. It glowed with a light that seemed far from natural and was almost too hot to hold. You flipped through the pages, all of which were blank.

"What a fucking rip off." you said, cursing your inability to make wise financial decisions

Lifting up the crystal and the book, ready to throw them across the room, you saw the light gleaming letters across the pages. It was like invisible ink. As you ran the light of the crystal through the pages, more letters became visible, first as runes, then as proper English.

"Greetings, new practitioner of magic. If you've stumbled across this tome, it means you've become interested in the magic of the Snow Elves. I appreciate your interest and congratulate you on your commitment. Before we can begin casting spells, we must first do one spell in particular:"

Despite this being the middle of the book, the passage read as though it were page one. The mystery deepened by the minute. You flipped to the next page to find a list:

Spell Name: Become
Ingredients: a cask of strong alcohol (no less than 45% APV), Two large cartons of milk, blue thread, snow, and an empty bowl with an offering of your own blood.
Arrange spell ingredients at each of the points in an upside down pentagram, drawn in chalk. Repeat the word "become Lamy" three times and the spell will activate. Once activated, you will then be able to practice other spells.

"It couldn't be real right?" you thought "this was just a dumb joke." You couldn't resist but try though. Thankfully the spell ingredients were easily acquired. You did your best to draw a pentagram, even if it came out poorly and set the ingredients at the points. You took a deep breath.

"Become Lamy."

For a brief moment, the ground beneath you began to shift and you began to sweat profusely. You clutched your chest. It felt like something was about to burst from your nipples, the pain was almost unbearable. Your nipples, thankfully, remained unruptured. Your ideal wasn't concluded yet, however. The ceiling above you began to recede from view slightly, as if you were being shrunk and your hair began to jut from your head at intense speed. Your beard that you'd spent nearly three years growing flew back into your face and your ears sharpened into a point. You collapsed from the pain. It was like someone had lit your entire body on fire, a fire hot enough to boil your skin. The worst was still to come.

You felt your loins begin to pulsate. All you could think to yourself was "oh shit" before you slowly, and painfully, felt your penis, balls, and scrotum start to retract within your body. You let out a yell only to hear a that of a high pitched woman. Your balls swam within your skin, taking shelter just within the front of your pelvis while your penis split open, forming a void within you. The sensitivity of your glans centralized into a small, pea sized point, mixing the unbearable pain with that of intense sexual stimulation. It was like the best and worst feelings simultaneously.

There you lay, sweaty and tired, on the floor. The pain had finally subsided, leaving you exhausted and panting. After some time you lifted yourself to your feet, feeling your ears. No mistaking it, they came to a sharp point. Looking down at your chest, you saw the result of that inflating feeling: massive boobs. You could barely keep balance with your newfound weight.

"That must mean..." you said, finally connecting the dots

You reached your hand to your groin to find not a shaft and balls, but a hole, radiating heat.

"Oh shit..." you said to yourself, again in that female voice "Ok. Ok... we can fix this right? Surely."

You took up the book only to find the crystal's light had vanished entirely. All the books contents were now lost on you. Panic filled every inch of you. Sure, it was every guys dream to turn into a woman, but thinking long term, he was up shit creek. What would he do when his roommates returned to find a nearly naked woman with elf ears and blue hair saying she was anon? Even if they believed that, there was no way they'd believe a magic book and a crystal transformed you into this!

You paced back and forth in a fit of anxiety. As your legs brushed past each other, you felt it: a deep, gnawing feeling within the depths below. Just the mere brushing of your thighs together sent waves of pleasure through your body, so much so you had to hold an orgasm in. You ripped away your now ill fitting clothing and went to work.

You gripped your ample breast with one hand, pushed both fingers inside your newfound orifice with the other. It was tight and unbelievably warm, like putting your hands against a heater. With a single roll of your fingers, you expelled an impressive amount of fluid from your system with a great moan. It wasn't enough; You rolled again and again, an effort that culminated in 3 orgasams in 5 minutes, the last of which sent such waves of pleasure throughout your body you shook in ecstasy.

You lay on the bed, covered in sweat and fluid, and gasped for air. You felt like you'd exercised more in those five minutes than you had in an entire week. You rolled to the other side of the bed, feeling a tidal wave of exhaustion overtake you. You'd figure out what to do tomorrow.
