"Hey, Angie! How are... jesus... you?"

"Um... are you OK, Jack?" Angie asks, eyebrow raised.

"Yeah, I'm fine. Just some stomach..." you pause, taking a deep breath as under the table Caoimhe's mouth continues to rub along your member, her warm hand wrapping around your balls as she gives them a gentle tug. "Just some stomach problems."

Angie holds out her hand, placing the back of her fingers against your forehead.

"You don't have a temperature. Are you sure you're OK?"

"I'm so good. Have you seen any good... any good movies lately?"

Jesus, your balls are so filled. You're ready to spray like a fucking fire hose.

"Um... yeah, I saw Sorry to Bother You. It was pretty cool, it was all about the exploitation of capitalism, and how the workers need to rise up and take power for themselves! Totally rad."

"That's cool. I should give..." Caoimhe's mouth tightens around the base of your dick, tickling your balls with her lip as she squeezes a bead of precum from her tip, letting her get a taste. "Give it a watch."

"Are you definitely OK? Do you want me to get the nurse?"

"No, I'm good," you stutter out.

Caoimhe gags loudly under the table as she takes your whole length in her mouth again, tickling your balls gently as she does it.

"What was that?"

"Sorry, I... I farted."

"Oh," Angie says, the look of concern turning to one of light disgust. "I... I'm going to go. You should hang with us soon, Sarah said she really misses having you over. Go to a doctor first, though. This isn't normal."

You nod, a response forming in your head but your mouth is unable to speak them, simply letting a groan out of your mouth.

"Seriously. Call someone," Angie says, before turning around and heading out the door.

Caoimhe's continues sucking, squeezing and tugging your balls and getting you closer and closer to orgasm. You let out one final moan, knocking your head back as your cock fires. Caoimhe sucks down spurt after spurt of cum, letting it splash along the inside of her mouth, her cheeks, her tongue, her teeth and her throat, coating it all with your pearly cum as she gets a great big taste of it.

After a moment, making sure the last of your cum is gulped down, before Caoimhe pulls away. She tucks your cock back into your pants, zipping it up and threading your belt again. You lean back, allowing her to pop out from under the desk and back to sitting next to you.

"Oh, that was good," you grin.

"Good job lying to that girl. What'd you tell her?"

"You heard her? So why'd you keep going?!"

Caoimhe giggles, smiling coyly.

"I found it really hot. I mean, your cock's amazing and your cum tastes great, the thrill of getting caught is hot, and one of my biggest fantasies is doing it in a library."

"I'll take that into account in future."

Caoimhe licks her lips, before giving you a quick peck on the lips.

"Good job with all that studying. Glad you liked your reward. Shall we hit the books again?"

"Do we have to?"

The look on her face tells you that it's a definite yes.

"If you do a good job, there's more rewards. Now, let's study!"
