Leave her hanging

"Hm," you say, reaching for your shirt. "I think that's enough, for now."

Madison lets out a disappointed noise that is akin to a scream. You almost laugh at the thrill of power. At how this all started with you wanting her, and now is ending with her wanting you.

"I just already have reason to believe that this was a good, productive session, Madison," you say, as you give her ass another, but much more gentle slap. "We'll pick this up later. There has to be some anticipation."

She gives you a furious grunt. She mewls as she tries to grind her ass against you, you just button up your shirt and step away.

You walk over to her desk and look at her math. You start working on it so that the right answers make sense, and so that it looks like she did them. When you are done, you stand up and walk back in to the bedroom.

Madison is lying there still, blinking now. Coherent but still somewhat stunned. She forms words as if it is difficult for her. "You're...like, leaving?"

"Yes," you say. "Honestly, I don't know whether you're on birth control, and I'm not in the habit of bringing condoms to tutoring sessions. But aside from everything, that's about all I'm willing to do with you tonight."

She looks pensive. "I'm like...not. On birth control."

God, she really is stupid. Good call, on your part. Still, you were able to have some fun.

"How about this," you say. "If you want me to do more, make sure you're on it or make sure either of us has a condom. I'm not doing anything else without that. Did you want to cuddle."

She looks up at you with a raised eyebrow. "If we do, I'll want more. And I, like...don't think that's the kind of thing this is."

You almost laugh. No, it isn't. Still, you go up to her and kiss her on the corner of her brow, and give her ass one last smack. She lets out one last pleasured whimper. Then you pick up your tutoring supplies and get ready to go.

"I'll see you soon," you say, as you start to head out. "Something tells me that this is going to be a productive relationship."

She grins, despite herself, as you exit the bedroom. You leave her single dorm room, and approach the elevator to your own.

You just hooked up with a ridiculously hot girl on campus, in your first week, and she outright wanted you to fuck her. Everything that they say about college is true...if you're willing to get just a little dirty. Satisfied with your day, you head back to your room and shower before going to bed.
