Roger watched as Mark carefully placed a similar glow stick in Mai's latex hand. Mark then activated the device, which started to glow the same colour as Roger's glow stick.
A few moments later, the colour changed to match Mai's glow stick, then returned to Roger's colour. Back and forth the device changed colours, each change coming faster, until the two colours started to merge, it was as though both colours existed on the device at once, separate, yet indistinct.
Roger glanced down at his glow stick to find the same colour merging occuring, and he noticed that Mai's stick also glowed with both colours. Suddenly, Roger felt strange. It was like he was inanimate, yet he could still move.
Without warning, both glow sticks flared up in brilliant white, and when the afterimage wore off, he found that Mai was now moving. Roger tried to react, but couldn't budge, not even to draw a breath. He felt like screaming, but no sound formed, and his mouth didn't move, not even slightly.
The glow sticks flared up again, and before the after image wore off, Roger knew something was very wrong. He could no longer feel his legs. It was as though he was sitting, even though he was standing. Mai's legs looked decidedly more natural, lacking the plastic sheen of the rest of her body.
Another flare left Roger wanting to scream even louder, as he felt his equipment shrink and absorb into his body. He knew that, were he able to move his hands, he would find a hole in his crotch. Mai's crotch sported a bulge, which left Roger with a feeling of envy.
The glow stick flashed a few more times, and with each flash Roger felt his sense of touch disappearing. He could no longer feel anything below his chest.
Another flash left Roger in shock, as he felt a great weight form on his chest. He could see Mai's cleavage was gone, replaced with a masculine set of pecs.
More flashes left Roger feeling nothing below his chin.... except for a strange feeling in the groin area. Mai was holding her... his hands up in front of his still plastic, feminine face.
With two more flashes, Roger knew it was over. His face changed, becoming more feminine, and then all feeling faded, leaving him with just sight, hearing, and a strange feeling in what had to be his groin. Mai was a fully male asian, and a hunk at that... Roger realised how strange that last thought was, and was worried about the effect of this on his mind.
Nevertheless, Roger felt a great desire to be used by one of the two men in the room with him.
"Roger, meet Jeremiah... JereMAIah, you see. Mai, meet Geri." Mark snickered at that last word. "You see, Mai got transformed by one of the other students, and was left as you saw him earlier. They then used him as we will be using you. When I researched the spell they used, I discovered that, while it wasn't permanent, it would last for a month. It's been roughly two weeks since then, and I have been working on a spell transference device to revert him to normal - problem was, I needed someone to receive the spell."
Jeremiah jumped in. "Thanks, by the way, man. I'm glad to be back." He licked his lips as he looked at Roger. "With my mind back to normal, I need a good fuck."
"Patience, Mai. We've got him for two weeks. I just want him to know what happened." Mark turned back to Roger. "You see, you have become the ultimate sex doll - any male who has sex with you will feel as though being fucked by a real woman, but you remain completely immobile, and have latex skin. My device transferred the spell from Mai to you, and now you are to serve your one and only purpose."
Mark then left the room, closing the door behind him, and Roger watched, helpless, as that hunk... Mai (Roger needed to remind himself) removed his feminine clothes, then Roger's now-useless clothes, and laid him down. Roger's mind transfixed on Mai's appendage, and the sex doll felt complete as Mai had his way with the sex doll.
A week later, after many uses, the sex doll watched as another student sneaked into Mark and Jeremiah's room, and stole the sex doll....
