His Virgin Valentine by Poppy Parker

Mia
Stanton St. James is my world-renowned genius professor, a total hardass, and utterly irresistible. I’ve wanted him from the first moment I saw him giving that lecture on DNA sequencing. Ever since, no other man will do. No matter how hard I try, I can’t get him out of my head. So here I am at twenty-one on Valentine’s Day, still the not-so-proud owner of my V-Card.
Stanton may be the only man I want, but I’m not doing well in his class. I really need to concentrate, but it’s difficult when every time his eyes touch me, I feel the heat rising inside. I just can’t hold back anymore, so I decide to wear a super-short skirt to class today. I hope it sends a message he can’t misunderstand.

When Mia Moore comes to my class wearing that tiny schoolgirl skirt, I can barely contain myself. I’ve wanted that girl since the first moment I laid eyes on her. Even finding out that she’s my old college friend’s daughter can’t subdue my deep animal need.
Mia’s grades are slipping, and I suspect the skirt is a ploy to bring them up. I never would have expected this kind of behavior from a seemingly innocent girl like her. I should send her away, ignore her obvious manipulation, and forget all about it. But the image of her is burned in my brain, and she’s the only balm my wounds can accept. I’m going to teach my too-tempting student the price for teasing me.
