Tamsin smiled at James, completely maintaining eye contact as she began to weave her spell. After a few moments the young man started to feel a little different down below. Looking beyond his waste James found a neatly trimmed vagina between his legs, but even more surprising was the large, familiar shaped bulge that was abundantly evident under Tamsin's skirt. Had she done what James thought she had done? The answer soon became clear.
The sexy student winked at James before moving one hand up her skirt and gently caressing her borrowed appendage. To James' surprise it gave him the same pleasant sensation he would have expected if it had still been attached to his body. Tamsin leaned in close, affording James a deliberate view down her partially unbuttoned blouse and giggled at his excited reaction as she began fondling herself more aggressively, expertly manapulating James' on loan penis to bring him to the brink of ecstacy. He shut his eyes and tried hard not to surrender too obviously to the overwhemingly blissful sensations this girl was putting him through in such a public setting. Then, just as he felt like he was about to explode with joy, she stopped. With a wave of the girl's hand a breathless James looked down to see his manhood back in place. Cruelly, the demonstration was over.
"If you want more where that came from, come see me after class" Tamsin promised. She smiled and blew James a kiss before strutting back to her desk while running one hand very deliberately through her hair.
"Well, what an interestimg choice of spell Tamsin" Elspeth cocked an eyebrow sternly, but there was enough of a smile playing on her lips to suggest she didn't dissaprove.
James barely cared who was next at this point, but another girl was about to be called up nonetheless.
