Unknown to Jon, Ms Lustby's special juice had suppressed Jons ability to change his body at will and would speed up its transformative affects if he tried.
His teacher chuckled to herself as Jon flicked his now longer hair from in front of his eye, still oblivious to the changes the semen was doing to his horny teenage body. Although it was now perfectly normal for her students to perform sexual acts in school she still got annoyed if it interupted her class. At least she'd have no more trouble from Jon, a bonus side affect of its magic was that it would make him much more submissive and open to suggestions.
John fidgetted in his seat his boxer shorts seemed to be riding up his crack, suddenly feeling quite snug round his now rounder ass and widening hips. He felt a breeze round his legs, almost like he was in shorts rather than the jeans he had put on in the morning. He looked down and gasped, they now where shorts to the knees and creeping higher, he gasped and pulled his chair out a little to get a better look, the lower part of his legs where now smoother, softer and more feminine in shape, they matched his new smaller feet and ballerina flats, which where once his trainers.
"Ms Lustby, Idon'tfeelsogood", Jon quickly squeaked in a worried, slighly higher than normal voice, as he ran out of the door to find somewhere quiet and safe. Again flicking his long side swept bangs out of his field of vision. As he ran his nipples started to feel sore as the rough cotton of his shirt rubbed against them and his legs felt more contricted at the thighs as his jeans now finished their metamorphosis into a short denim skirt. He had reached the restrooms, heading into the girls one because it was obvious what was happening to him and he didn't want to think what would happen to him if he got caught in the boys one (though he breifly did and because of the nature of his earlier spell it didn't disgust him). Luckily the room was empty, but he rushed into a stall just in case anyone else came in and closed the door.
Leaning against the door and looking down at his now very feminine lower half, he concentrated as hard as he could to change him self back, as he did his back slid against the door as he lost more of his height until he was a petite 5'1" and his whole frame looked more smaller and feminine, now blonde hair tickled his shoulders and the top of his back, he felt a quick tug upwards in his crotch and knew he was now technically a she. "
"Why..... did I make that stupid wish" he said grabbing his now slender neck, with no trace of an adams apple, supprised by the sweet girly sound of his new voice. With all the will he could muster he tried again to change himself back. Bam, a perfect pair of D-cup breasts expanded to fill what once had been his t-shirt, but was now a nice pink bra to match his panties and tight pink midriff baring top. His face felt strange for a second, kind of like it was being massaged and then stopped. Realising the changes where now complete he stepped out of the stall and stood slack jawed staring at the mirror opposite, he was easily now the most gorgeous girl in school.
He snapped out of being mesmerised by his pretty face and ample cleavage, when he thought, 'Oh no, the stone, I left it in my backpack in class, I could end this wish and change back if I had it on me'. But he wondered how he would make it back, the boys would want their way with him, there was no doubt about that, but he needed that stone quick, what if somebody stole his bag.
He went to go out the door.........
