As the light faded, Jamie could feel a tingling in his body and his mind that dove deep into his subconscious, seeking his innermost desires. The unknown force found what it was looking for in his desire to experience ultimate pleasure. With that, the medallion set about fulfilling it.
Jamie soon felt the tingling grow stronger in his crotch as his boxers began to become tighter and an errection formed, but his member continued to grow past its usual size, straining the fabric of his underwear. Jamie watched in wonder as his manhood grew and grew until the fabric relented and unleashed the now 12" member. Awestruck at the marvel, he began to feel a tightness in his balls as they too swelled in size until reaching a size similar that of baseballs.
Amazed, and extremely turned on, Jamie did what any man would do and reached out for his member and began to stroke it, nealy loosing it as he was unprepared for the increased sensitivity. Stroking faster and faster, feeling pressure build in his testicles and finally unleashing a torrent on the wall he was facing.
Relling from his orgasm, Jamie took a step back and was shocked to see so much cum in one place.
"That came from me?" A smile formed on his face until the tingling returned, this time it was all over his body. Jamie began to wonder just what the medallion was going to do to him now and he turned to the full-length mirror in his room and saw his body began to become more slender from his rather bulky physique.
It wasn't until midway through the transformation that he realized his body was becoming female. "No! This isn't what I wanted, change me back!"
"Oh contraire, you want to feel the most pleasure possible and this is exactly how you will get just what you've always wanted", said the voice of the medallion ,"and I will get to take my revenge on this miserable world for imprisoning me. So sit back and wait for the changes to finish before you accuse me of lying".
A tightness in Jamie's chest forewarned him of the next change and his pectorals began to swell in size as they formed into a pair of breasts. Jamie tried, and to little success, to push his expanding breasts back into his body, but all that happened was his hands were pushed further from his body as they expanded further with each heart beat. Surging past C and into the upper DD range before stopping at DDDs. Next his hips pushed outward, followed closely by his posterior. His butt continued to swell until it began to look like two halves of a basket ball rather than a man's ass. With each change, Jamie came closer and closer to another orgasm. The change that pushed his over the edge was when his nipples pushed out of his now large tits and grew to about 1/4 inch long. The mind bending orgasm caused him to fall to his knees.
With all the changes happening to him, Jamie never realized the addition of a woman's slit behind his balls until he felt his juices running down the inside of his thick thighs. Looking up at the mirror he saw all semblance of his former self disappear as body and facial hair fell off, while the hair on his head grew longer and thicker until it reached the small of his back. "What have you done to meee..." his/her now very feminine seductive voice changing into a moan as even more alterations were made to him.
Jamie began to feel the tingling intensify to painful levels, that still caused him some measure of pleasure. Grabbing the sides of her head, Jamie was overcome with an incredible headache. Opening her eyes and looking in the mirror, she looked in horror as two lumps on her forehead pushed outward until the skin gave way to a pair of black horns that curled backwards like a ram's horns.
"Wha-ahh!", Jamie yelled as her tongue snaked it's way out of her mounth between two growing fangs, lengthening and developing a fork at the tip. Her skin began to feel like it was on fire and it took on a crimson hue. The increase in temperature causing her to begin panting. A sharp pain in her shoulder blades pushed her on to all fours until a large pair of red and black bat wings forced their way from her back, followed closely by a 4 foot long thick tail that tapered to a point that emerged from the base of her spine.
