Descartes

"It's Descartes, right?"

"Excellent!" Caoimhe grins. "See, you know so much!"

"So, do I get my reward," you say, nodding towards your hard cock.

"Fine," Caoimhe says, beginning to blush.

Her eyes dart around the room as she makes sure no one can see under the desk, before she pushes her chair back and drops to her knees, scurrying under the desk. Her slender hands slide up, unbuckling your belt and sliding it free of the loops. She pulls the zipper down, letting your cock slide out. Caoimhe pulls your chair slightly more under the desk, leaving you only able to see the top of her head. Caoimhe's lips press against your cockhead, tickling the sensitive skin of your knob as your foreskin slides back, letting her take the head in her mouth gently. Caoimhe sucks on your fleshy cock head like its a lollipop, sliding her mouth down your length as her head slides against the back of your throat. You let out a low rumbling groan, wincing as you've overcome by pleasure as she slides down your cock, her lower lip quickly pressing against your balls, her saliva running down your cock and meshing with your pubes.

She might be helping you with your studies, but goddammit, you've taught her how to give a good blowjob.

"Keep sucking, baby. God, this feels really good!" you say. "Shit, I should've really studied a lot harder if these are the rewards!"

"What rewards?" a voice asks.

You turn your head, noticing Sarah's friend Angie walking past, carrying a thick chemistry textbook. Her blonde, straight hair is mostly hidden away under a beige beret, her cute, sexy smile gleaning at you.

Surprisingly, however, Caoimhe continues sucking, your cock head still in her mouth as she sucks hard on it, forcing you to suppress a whimper. Fuck, either she hasn't heard Angie or she doesn't care at this point, because she keeps sucking.

Time for a new... Jesus fuck, that feels good... for a new plan.
