The Invisible College of Magic: Book One: Water. The Invisible College of Magic, #1

The Invisible College of Magic is the multiverse's finest educational institution for wizards. That doesn't mean its students don't have time for plenty of extracurricular activities which is mostly sex. A shapeshifter. An enchantress. A centaur. A half-demon. A fire wizard. An earth wizard. All of them magical and all of them lusty for the kinkiest sex in the Invisible College of Magic. They're all being hunted by a mysterious predator while they carefully study the strangest of phenomenon: sex in every possible kinky permutation.
Tom "Shifty" Varieg is a natural shapeshifter who is intent on bedding as many fellow students as possible. It doesn't matter to him if they are human, demihuman, or something else entirely. Since he's willing to change himself to suit the needs of his lovers, he's always in high demand. But his shapeshifting can get him in more trouble than he anticipates. This is a 10, 000 word novelette intended for adult audiences.

Excerpt:"Do you know what' I'm thinking?"She rolled her big, beautiful brown eyes at him. "That's telepathy, not precog or premonition.
And I can tell what you'll be doing in about five minutes.""Oh? What's that?""You're going to be having sex with me."Shifty knew an invitation when he heard one. He stepped close to Estelle and kissed her. She eagerly kissed back as he pulled at her vest. The buttons came open quickly and easily, allowing him to cup the centaur's breasts. Shifty slid one hand down her back, looking to grope her bottom, but instead encountered her very equine withers.
It caused him to pull back from her kiss."What's the matter?" asked Estelle, already knowing the answer and a bit angry at it."Nothing! I've just never done this with a centaur before."She smirked. "And I've never done this with a human boy before. So what? You going to leave?""Of course not!" he protested, offended that she'd think he'd give up a chance at pussy. Shifty didn't discriminate between human and centaur.
It was all good to him and he was always willing to try a new experience."Then why did you stop kissing me?""I wanted to ask if you something very.personal."
