He acts as though nothing is wrong

"..." The silence on the other end was palpable, though only on Tom's end. Sarah didn't stop moaning as Jeremy continued thrusting into her, pushing her into the sink with each slap of his hips on her ass. She didn't even care about pretending anymore, she couldn't give a fuck if Tom knew she was up to. No, actually, that wasn't quite true.

She wanted him to know. She wanted him to know some young, hot student was fucking her in a way he was never going to be able to, not as she was now. She wanted him to feel pathetic and weak and pitiful.

Nearly a minute must have passed before Tom said anything. "...your, uh...your food must be good."

She laughed. The sound bounced around the small bathroom's walls, echoing its cruelty, and she heard Jeremy add to it with a small chuckle of his own. Even the sweet cinnamon roll of a student was laughing at Tom. "Yes, Tom, I'm enjoying myself quite a bit," she replied, voice full of lust.

"Well, um, I guess I'll see you after we're both finished with work for the d-"

He didn't get a chance to finish the sentence, because Sarah could hear that sadness, the anguish he was trying to hide, and she yearned for more. This useless old man thought she was still his wife? Still his? It was time to rub it in his nose that this wasn't the case. "No!" she commanded, and she heard his breath hitch at her tone. "No, the call isn't ending yet. And as for meeting up after work, it will have to be quite a bit later, I have an important one-on-one to go to."

His voice was shaky when he spoke again. "Y-yeah? Who, um...who with?"

It took a while for Sarah to answer him, because she was too busy moaning, "Yes, please, I'm getting there, harder, deeper," before she finally turned her attention back to Tom. "Oh, just Professor Waxly. He wanted to talk to me about those things I'd told you I wanted. Apparently, your appeal wasn't worth much, if anything, so I'm going to have to talk to him myself, at his home." She made no effort to conceal in innuendo in her words.

Just as she'd asked, Jeremy stepped up his work, fucking her as hard as he could, while on the other end Tom struggled to think of something to say. "Well, I'm...glad you're going to have that opportunity." That was when she heard it.

That obvious determination to do something about what was going on. Sarah couldn't have that. "Professor Saunders, listen to me, clearly!" she snapped at him. "You are not going to even think of using that coin on me today. If you do, that is the last interaction we are having, period. Do you understand me?"

"Y-yes..." he replied, defeat clear in his tone, and Sarah knew she'd won. That victory, combined with the lovely sensation of Jeremy doing his best to fuck her into bliss, sent her over the edge.

"Oh yes~" she moaned, pressing the phone as close to her mouth as possible so Tom could hear every word. "Jeremy, you're doing it, you're making your professor c-cum!" He must have been holding back, because as her pussy clenched onto his cock, he orgasmed as well, filling her with his young, virile seed. "That's it, perfect, fill me up, fill me with your cum!"

At some point, the call ended, but Sarah had trouble caring, she'd gotten everything she wanted out of her lunch. Tom now knew thoroughly the situation he was in, how he'd fucked up by getting into this circumstance with his egotistical wishes. After cleaning up and giving Jeremy a few compliments, Sarah went back to work, eager to finish up and get to the real accomplishment to work on: fucking her way into everything she wanted.
