Corrupting Ms. Perez

Still chuckling, Mr. Dinger fiddled with the ring on his finger, twisting it reflexively as he pondered how to take this further. Already he had one of the brightest students in the school shamelessly fucking herself with a sex toy on his desk, mewling loudly after having told his all the naughty, sluttish things she and her friends did after gym practice. The arrival of his colleague, Ms. Perez hadn't been expected, but he'd dealt with that sudden development rather nicely. Now she believed that her stripping down to her sexiest underwear and showing off what was now a dangerously sexy body was her idea of a suitable punishment for having poor Jennifer on his desk, near naked and bucking like the slut she was. Never mind the fact he'd just made exchanging sexual favors permissible for extra credit.

He turned back to Ms. Perez, who still stood uncovered before him, her internal struggle clear across her brow. He decided to make it easier for her. "And how exactly is the deal a transactional one, if you don't mind my asking?"

"Well," she stammered, still struggling to justify the difference to herself, "Sometimes, the stress of being a students gets overwhelming. You remember! The tests, homework, peer pressure... It's a lot for them! We, the teachers and I, provide a service that allows them to get rid of their accumulated stress AND they get extra credit to boot!"

"Right, right" Mr. Dinger nodded along, as though everything she was saying made perfect sense. In truth, he couldn't care less how she justified it, he was about to change the rules of the game once more anyway. "But, when it comes to relieving stress, wouldn't you say it helps the teachers more than the students?"

"Well, yeah! I mean-" For the first time since she'd stripped naked, she blushed, embarrassed. "Teaching is just as stressful! Having to handle all those kids as they make fun of each other, constantly fight the rules, and refuse to do their homework... It's not an easy job!" She nodded then, finally reaching a satisfactory conclusion for herself. "So yeah, it's nice being able to let loose a little and blow off some steam with a couple orgasms."

"Is that why you're all so dominant with them then?" He asked, feigning confusion. "I've seen the way you fuck them - the girls can barely breath while you're sitting on their faces! The guys too, when you're not busy pegging them anyway. I know the transaction states penetrative sex, but..." He slowly trailed away, realizing he'd been framing his point wrong. "Wait, that is how you fuck them, right?"

The question properly phrased, he suppressed his grin when he saw Ms. Perez nod. "Yeah, you're not wrong about that." However, she quickly took offense at his line of questioning, her hands huffing on her hips. "And what is exactly so wrong about the way I fuck my students? Like I said, teaching is stressful! I need my release too. Sometimes it just requires a more... dominant hand." She paused and closed her eyes, smirking at a memory. She then gestured to poor Jennifer, still lost in the throws of self-pleasure on his desk. "Now stop avoiding my point, Dinger! You have no right to have this young girl in this state after hours! You don't fall under the definition of a 'hot female teacher' as written in the Sexual Exchange Extra Credit Agreement! Nor is this at all transactional!"

"She came to me!" He defended, using both hands to point at the young senior. His dick, still exposed, flopped against his stomach as he let it go. "This poor girl is so oversexed that she walked up to me after class hours, begged for the chance to fuck herself on my desk, all while asking whether I knew of a loophole within the Agreement that would not only let this be permissible, but also count for potential extra credit! Isn't that right, Jennifer?"

At his question, both of them turned to the girl, still thrusting herself against her pink toy. Two fingers dancing across her clit, she bit her lip to mask a moan while she nodded. "He's right! God, I'm sorry Ms. Perez. I'm just such a slut, I just couldn't wait until I found a hot teacher like you to help me. It doesn't help that I've been feeling rebellious lately; the girls are fun and all, but it's just so stressful, having to balance my grades and my soccer practices. I needed a teacher to help me, and Mr. Dinger was the only one available."

The girl was near tears now, both in shame of what she'd done and in how sexually frustrated she's been feeling. Ms. Perez, hands still on her hips, took a long moment to look between Jennifer and Mr. Dinger. Minutes passed before the school teacher sighed, shaking her head.

"I suppose this is as much my fault as anyone's." She said, exasperated. "As a teacher who falls under the agreement, I should be more attuned to my student's needs and help those who need it most." She seemed to make a quick decision before nodding to herself. "Well, it's a good thing I stayed late helping another student." She snapped at the masturbating girl, making Jennifer jump. "Come! Jennifer! Hop off that desk, will you? God, why is that thing so blanched?"

"Sorry!" the teenager blushed, climbing off the dildo with a loud SHLUCK. "I get so wet sometimes, I can rub paint off the walls."

"Well, lay down on the floor then." The scantily-clad teacher ordered, pointing down. "Not much paint there to rub off with your cunt juices."

Next to them, Mr. Dinger chuckled, unable to ignore the more commanding presence his colleague was portraying. "Do you at least have a pillow for the poor girl?" He asked mockingly. "The floor isn't very comfortable."

"Of course I do!" Ms. Perez barked, making her way to a discarded bag that Mr. Dinger was half-convinced wasn't there before. He glanced over her shoulder quickly as she rummaged through it and saw that it contained a large strap-on and various lubes. His vision was obscured before he could see more as she pulled out a heavily stained pillow, the teacher examining it quickly before tossing it to Jennifer. The student quickly placed it on the classroom floor, resting her head upon it as she laid down.

Ms. Perez marched over to the senior, placing her feet on either side of the young girl's head. Preparing to squat down onto her, she paused to turn at Mr. Dinger.

"Well? Are you gonna give us a bit of privacy?"
