The swap seemed to happen instantaneously, and suddenly David could feel a draft on his legs, among other things. It was also as though his boxers had shrunk and were now restrictive on his junk. Not to mention the unfamiliar garment tied around his chest. Looking down at himself he was stunned to find himself wearing Professor Yamamoto's clothes, her grey skirt suit, blouse and high heels, even her underwear apparently. However his body was the same, which meant his hairy legs were now on display. Holy shit! he gasped.
"What's wrong David?" Chelsea asked, causing him to look up at his favorite professor, now attired in his male clothing. Funnily enough she still looked hot to him, her nipples were evident through the fabric of her new t-shirt since she was no longer wearing a bra.
Tensing his toes up inside his new pumps, David scratched his head, feeling somewhat self-conscious about suddenly wearing women's clothing in front of so many other people. "Nothing, just er... I'm fine." he replied.
"You sure?" Chelsea again inquired, folding her arms, as David glanced down to his former sneakers, now resized to fit Chelsea's slender, smaller feet in the same way her heels had resized to fit his feet.
"Sure I'm sure." he smiled, as he felt his cock now straining against the fabric of Chelsea's former panties. The whole thing was so kinky to him, to be wearing his favorite teacher's feminine clothing, still warm from her wearing them. Then as their little chat continued, David picked out a random, average-looking female student wearing shorts and swapped his body hair onto her. Her once smooth legs now sprouted coarse hair, as did her arms and everywhere else on her body, even some on her C-cup breasts. As for David, as proven by his legs, he now had hairless skin, and he felt a little better about himself.
As Chelsea seemed more interested in asking about David's studies and other aspects of his college life, David was now trying to decide whether he should keep swapping with Chelsea, or reverse the swap... since he liked her so much.
He could of course swap with other girls around him, or just go back to swapping others.
