Alexa sat at her desk with her head resting on her folded arms and tried very hard not to yawn. Some people might think a sex ed class might be interesting, even a little hot, but so far this year had proven to be nothing but boring anatomy diagrams and droning lectures from Mr. Jones, a balding middle-aged man who was supposed to be a football coach most of the time. Right now he was droning on and on about glands and sex hormones or something, and Alexa could only hope she could remember enough of it to get a decent grade on the next quiz. Glancing a few desks down she saw her boyfriend, Brian, looking equally bored, and shot him a wink, which he returned. Maybe later they could find something to regarding the parts Mr. Jones was rambling about that would be a bit more... interesting.
Suddenly a warm breeze wafted through the classroom; Alexa sat up straight as it rustled her hair, and around her she could see everyone else doing the same. There was a sudden shimmer in the air, and then suddenly there was a woman standing beside Mr. Jones. Alexa couldn't help but stare - she'd never seen anyone quite like her before. The woman was shapely and voluptuous, with large firm breasts and rounded hips, and she had a face that would put any actress or supermodel to shame. She was wearing nothing but thin cloth wound around her loins and breasts, and Alexa felt her breath catch as she wondered at what might lie beneath them. That seemed odd - so far as she knew she was straight as they came and had never been attracted to another woman before - but she couldn't help it; this strange visitor seemed to ooze sexuality and irresistible fascination. All of the other students were staring at her and seemed equally spellbound, even Brian, but Alexa couldn't blame him. Attraction - arousal - seemed the only reasonable reaction to this woman, this... vision.
Mr. Jones turned to face her and went a flustered red in the face. "Er, you're not supposed to be here," he said. "I'm going to have to ask you to leave, ma'am."
"Oh, there's nowhere better for me to be," the woman said, her voice as sensuous as her body; Alexa felt herself panting slightly and couldn't ignore the feeling of arousal between her legs. The stranger walked over to Mr. Jones, her hips swaying majestically, and then planted a kiss firmly on his lips. For a moment, nothing happened, but then the kiss broke and the teacher stumbled back, and he seemed to be - growing younger? His hair was filling in, his wrinkles and paunch were vanishing, and suddenly, boring old Mr. Jones looked kind of... hot?
"Much better," the woman said, then turned to face the class, swaying seductively. "My name is Aphrodite to some; Venus to others. You might have heard of me. It has come to my attention that this class, which concerns the ancient and sacred arts of love, is not fulfilling it's promise. I'm hear to correct that. Let's get started, and I promise you that you will never think of love the same way again." she smiled. "Now, what shall I do for you first?"
