__________________________________________________________________

It wasn't until Friday, two days after he'd fucked Kayley in the P.E. storeroom, that Mr. Radley realized he was lusting over the girl more intensely than any of the other students he'd seduced. This was a slow-dawning revelation, one that didn't hit him until he realized he'd spent two entire lunch breaks watching the videos he had of her, loop after loop of Kayley fingering her pussy, licking his cock clean. In both, she had the same desperate expression on her freckled face, cheeks flushed and blue eyes wide. It was that look Mr. Radley couldn't get enough of: When he jerked off to them (which he had multiple times in the last forty-eight hours, surprised at his sudden stamina. That was the first hint, he saw now), he found that intoxicating mix of arousal and shame made him harder than anything she was actually doing.

He wanted to see it again, feel her body writhe against him. He found himself watching Kayley during class, lost in memories of what he had done to her, and plans for what he would do to her. Much as he'd wanted to take her again and again, Mr. Radley restrained himself for the rest of Wednesday and all of Thursday. He got to have her any way he wanted five more times; no sense in rushing it.

Besides, the teacher found himself thinking, if I play my cards right, I might get to have her even more than that.

Such a thought was not typical of Mr. Radley. He'd always honored the agreed-upon parameters set down by the girls; most of the time he even let them take the lead in deciding what to do, giving no suggestions or orders unless asked. But Kayley... Kayley was different. He still wasn't sure that even she knew how far out her boundaries went. Everyone he'd been with before would have balked, even called off the whole deal, if ordered to kiss their boyfriends with lips still salty with his cum. Not Kayley. She hadn't even hesitated.

He wanted to see how far she'd be willing to go. Wanted to see if she'd come back to him even after she'd earned her A, still craving his cock even as she planned a life with that idiot Travis. He'd never wanted this of any girl before. It troubled Mr. Radley, a little, but he resolved not to be disappointed if he never saw her again once this was done. It was safer that way, in any case.

But a man can dream, he thought.

Mr. Radley almost made it to the weekend without coming on to his student. He figured the recordings would be enough to get him through, watching them through most of Friday's lunch, stopping with enough time for his hardon to vanish before he had to stand in front of fifth period.

Fifth period. Kayley's class.

He thought the videos would be enough. The moment after the bell rang, and she walked into the room chatting with a couple of her girlfriends, he realized that he was very, very wrong.

It wasn't as if she ever dressed sexy (that time with the tanktop aside), and she certainly hadn't pulled out any stops today: Kayley wore a baggy school hoodie over athletic leggings. The hem of the sweatshirt stopped halfway down her ass. Mr. Radley couldn't see much, but he could see enough. Each cheek was perfectly outlined in black fabric; when she turned to take her seat, he was entranced by the crease where thigh met hip, remembering the paleness of her skin, the way her legs clasped around his waist, urging him deeper.

All of the sudden, Mr. Radley was very glad for his podium.

He had to have Kayley somehow, some way, and he had to do it today. Yesterday, he'd overheard Travis going on about taking her out on a date tonight, so Mr. Radley figured after school was a no-go. He'd already had planning and lunch, and there was no way to get out of teaching his last two classes without arousing suspicion.

What could he do? He scanned the room, looking everywhere but at Kayley. They'd just finished essays on Charles Dickens. It was one of the assignments she had neglected to complete. At this point, that was fairly common knowledge among her peers. None of them would think anything of him calling her back to his desk.

It came to him: Movie day.

Mr. Radley shushed the class and quickly ran through roll. No sooner had he called the last name than Tommy Thacker, one of the bigger slackers in class, raised his hand.

"What, Tommy?" Mr. Radley sighed. Several students giggled.

"Yo, Mr. Rad, seeing as it's Friday and we've been working so hard on those papers-"

"They've been working on their papers," Mr. Radley interrupted, gesturing at the rest of the class, "but you certainly haven't."

It was true. Tommy used ChatGPT to compose his, and then hadn't even bothered to go back and edit it. Mr. Radley had never been so excited to fail a student.

Undeterred, Tommy continued, "yeah, we've been working so hard, and I was just thinking we deserved a break. Senioritis kills, man."

The boy made finger guns at him. Mr. Radley grimaced, said, "You know, I could pretend you just threatened me and get you expelled, right?"

Tommy sputtered, almost falling out of his chair as his classmates laughed. Mr. Radley let them have at it for a bit, then shushed everyone.

"Well, it's a cold day in hell, because for once Tommy and I agree on something. You all have been working hard, and now I have a mountain of essays to score and several students to check in with. So yeah, you get a movie day."

There were cheers from several students.

"It's Oliver Twist," he said.

Several more students groaned.

"Hey," he said, turning the projector on and heading back to his desk, "Beggars and choosers, right? And you can be on your chromebooks. No games, though."

It took him a minute to pull up the '90s TV movie version, a little longer for the class to get settled and quiet once the lights were off. Mr. Radley hit play, and, along with the movie, began his plan for Kayley.

***

Kayley startled in her seat when Mr. Radley called her name. Inwardly, she groaned. She should have expected he was up to something the moment he agreed with that jackass Tommy. As a teacher, Mr. Radley was as much of a taskmaster as when they fucked. He went bell to bell with his lessons, not even giving downtime between big projects. It was an exhausting class, moreso now with the threat (she wasn't sure if "threat" was the right word; she had agreed to this, was actively enjoying this, after all) of him calling on her to fulfill their agreement.

She had a date with Travis tonight. She didn't want to fuck her teacher before going out with the guy she actually loved. Didn't want to be thinking of Mr. Radley's cock while they were together, nevermind the fact that his cock was all she'd thought about this week.

But. She'd agreed to anything in order to raise her grade to an A. She didn't really have a choice. Immediately, her stomach was suffused with the now-familiar sensations of lust and guilt- not that these feelings were ever that far away now. She'd wandered through the last two days in a fog, trying to process all that had happened since she showed up begging for a better grade. She'd done things for Mr. Radley she'd never done for any boyfriend, things Travis would have been disgusted by. Things she was disgusted by, things that kept her up at night wondering what kind of person she actually was.

Because all of those awful things she'd done made her hot as hell.

Mr. Radley hadn't bothered her the rest of Wednesday and all of Thursday. He was giving her a break, Kayley figured. She still had to make him orgasm five more times if she wanted her A, and with a month to go in the school year he had plenty of time to take advantage of that. So why today of all days?

Standing, she made her way to the back of the room. Much as she worried, none of the other students even glanced at her, too absorbed in the movie or their laptops to pay her any mind.

A second chair was pulled up beside him. The surface of the desk was clear except for his desktop computer and a smaller Chromebook. Together, they made it difficult for anyone looking to see what was happening behind the desk. Kayley remembered the last time she'd been back here, naked, half bent over, his fingers plying her slippery clit. The warm feeling in her belly dropped lower.

Oh God, she thought, that was only four days ago.

The chair was close enough to make their thighs touch. Kayley regretted wearing leggings and a baggy hoodie today. Underneath she wore nothing but a sports bra. Only a couple layers of fabric separated them. This was the closest she'd been to Mr. Radley since they'd fucked. Just a hint of his musky scent threw her back into the storeroom, his big, bare cock completely filling her pussy.

Here, now, Kayley felt her panties dampen at the memory.

"What are we doing, Mr. Radley?" she said, her voice shakier than she would have liked. The speakers, mounted on the ceiling a few feet away, were loud even though they faced away from her. She realized that unless she spoke loudly, no one would have any idea what was going on.

"Make-up work," he replied with a sly smile. He tapped the Chromebook and the screen flickered to life. It was open to a blank Google doc titled, "Instructions." Kayley found herself focusing on the blinking cursor, the promise and threat of all that empty space. He continued, voice pitched low, "I'm just going to type directions here, and you need to follow them."

His hand found her upper thigh, squeezed gently. Despite herself, Kayley leaned into it, pressed her leg against his. She couldn't look away from the back of her classmate's heads as Mr. Radley's fingers slipped between her legs, sending an electric thrill shooting up her middle when a pinkie brushed against her pussy.

Kayley sucked in a breath, whispered furiously, "Everyone's here!"

Mr. Radley took his hand from her lap, typed three words:

You said "anything."

"I did, yeah, but that was before I knew you'd want to mess around during class," she glared at him, angry and horny at the same time.

He typed some more, each word that appeared on the screen worse than the last:

Okay then. You have three options: 1. Call off the deal. 2. You have to make me cum an additional time, to make up for this, or 3. You do what I say.

He sat back in his chair (the same chair he fucked my tits in, Kayley thought, the same chair where I masturbated for him), crossed his arms. Her teacher's expression was mild. He was waiting, she understood, like he always did when he forced her to make a choice. Calmly. Never a hint of anger or disapproval. He loved doing this to her.

If she was honest with herself, Kayley kind of liked it too.

Did she want to call off the deal? No, that simply couldn't happen. There was no other way to graduate in time, keep her scholarships, keep her future. Keep Travis.

Did she want to fuck her teacher eight times? Part of her very much wanted to, wanted to fuck him as many times as she could before she left for college. That was the part of her that loved the taste of his cum, that let him fuck her bareback, that even now was becoming aroused at the thought of fooling around behind the entire class's backs. Another, quieter part just wanted this over as soon as possible, so her life could get back to normal and she could stop obsessing over an adult man's cock.

Could she even go back to normal after all of this?

Did she want to?

"Okay," Kayley sighed, "what do you want me to do?"

Mr. Radley began to type again. It was all Kayley could do to keep her mouth from dropping open in shock as the words formed on-screen.

Go to the bathroom. Take off your bra and panties.

Resigned, she stood, made her way to the door. Kayley stepped out into the hall without looking back at her teacher, not wanting to see the smugly satisfied expression on his face, not wanting to admit how right he was to be so full of himself.

Once in the girl's restroom, she ducked into a stall, wasting no time in following Mr. Radley's orders. The bra was easy; panties less so. She had to sit on the toilet and awkwardly shuck off her flats, then roll her leggings down before removing the blue no-show thong that kept her modest. She saw the glint of moisture between her thighs, couldn't help but slip one finger between her bare labia to find these exertions and the promise of what came next left her very wet indeed.

There was no way Mr. Radley would fuck her with the entire class in the room, right? This was just so he could mess with her, make her cum silently for the enjoyment of control. She'd jerk him off, and then they'd be on their way with no one the wiser. As long as she got to cum, Kayley figured she'd be fine with whatever was about to happen.

She got dressed again, underwear stuffed into the belly pocket of her sweatshirt. She checked herself in the mirror. The hoodie was baggy enough to hide the loose sway of her braless tits, but the leggings were stuck in an unfixable state of cameltoesis without the thong. The hem of her sweatshirt just barely skimmed the top of her mons.

Kayley took a deep breath. No one would notice. The room was dark, her leggings black.

Probably. There was still the hallway to get through.

Luck was on her side as she scurried back to Mr. Radley's room. The hallways were empty, and no one looked up when she slipped through the door. Her teacher was doing something with the chromebook; more instructions, probably. He sat back and looked her up and down as she approached. His smile was as smug as she expected.

Kayley plopped back into her seat. Mr. Radley's hand returned to her thigh, gently rubbing his way up, kneading the soft muscle with strong fingers. Despite herself, Kayley relaxed. Her body had learned just how good his hands could make her feel- and his tongue, and especially his cock- and responded automatically to the touch. She tensed only a little when he came to the junction of thigh and torso, the side of his hand pressing with a firm gentleness, then sliding so it followed the line of her labia. She parted her legs to give him easier access, and he cupped her pussy, middle finger rubbing her slit. The girl squirmed. By now, Kayley's leggings had soaked through. Her teacher gave a low chuckle when he found her dampness.

He continued teasing her through her leggings a little longer, then slid his hand up under her hoodie until it brushed the underside of one breast. His fingers found her erect nipple, pinching and tugging on it until Kayley had to bite her lip to keep from crying out.

"Good girl," Mr. Radley whispered, withdrawing, "I like it when you follow my instructions."

The Chromebook screen was dark. He tapped the touchpad, and it lit up. On the doc, the black rectangle of a video now took up most of the screen. Another tap, and then Kayley was there, naked in her teacher's chair, legs spread, fingers buried in her cunt. She felt the air catch in her throat as the clip continued. She'd never seen herself from this angle, found herself fascinated despite herself. Her tits were slack and sticky with runnels of semen, her lips swollen, glistening, parted in silent orgasmic cries. An abrupt cut, and the scene changed to an ill-lit storeroom. There she was, dragging her tongue up and down Mr. Radley's half-hard cock, her eyes wide and locked onto the camera.

Fuck, Kayley thought when the recording of herself smiled, I look hot.

Mr. Radley saw the change come over his student, her face slackening from shock to acceptance to arousal as she watched herself. As predicted, he thought smugly. Leaning close (but not so close a student who looked back would think something inappropriate was happening), he whispered, "Want to make more sometime?"

Kayley nodded, not looking away as the clip looped back to the beginning.

"Good," he said, adding "You want me to send you a copy?"

At that she broke away from herself, turned to look at him, then glanced across the classroom. No one was looking back at them. Two kids even had their heads down. Not trusting herself to speak, she nodded in affirmative.

"Good," he said, taking her hand and placing it in his lap. Her hand found his hard rod, straining against denim, and squeezed gently. He added, "You don't have to stop there."

Mr. Radley held in his own hiss of satisfaction as Kayley undid the button, then slowly drew the zipper down. Her deft fingers traced the contours of his cock, rubbing up and down his length, occasionally slipping lower to gently caress his balls. The area around the waistband was already soaked through with precum; with a coquettish smile, she slipped one finger past the elastic and pulled it down just far enough to reveal the swollen head of his cock, and the clear bead of cum on its tip. Kayley traced the sensitive flesh with two fingers, before swirling it around the glans, taking care to scoop up as much precum as she could. Then, after another quick, nervous glance at her classmates, Kayley withdrew, fingertip glistening, and licked it clean. She smiled again, and with her free hand reached for the Chromebook. Now it was her turn to type:

I love how u taste

Good God, this girl was going to be the end of him, Mr. Radley thought. To fuck the girl in the store room was one thing, but this was a whole new level of risk. There would be no way to explain this away if another student saw. He wanted nothing more than to throw her on the floor behind his desk right now, rip her leggings off and fill her to the hilt. He wanted Kayley gasping beneath him, wanted to hear the sound of skin on skin, of wet cunt tight around hard cock. He found himself trembling with desire, did a bad job suppressing it as Kayley cupped her hand and spit into her palm, before briefly clenching it into a fist. Then, without any hesitation, she plunged her entire hand into his underwear, coating him in her saliva. Her slick fingers massaged his shaft while the heel of her hand gently squeezed the head. He couldn't believe how good it felt, even as his heart pounded at the thought of getting caught.

Kayley watched her teacher's face as she caressed him. She could see the struggle to maintain composure in the way his jaw clenched and eyes scanned the room. He breathed in and out slowly through his nose, hand squeezing her thigh tightly with every twitch of her fingers. She'd never seen him so tense. And it was because of her, and what she was doing to him. Fascinated by this sudden feeling of power, she felt, somehow, her pussy get even wetter.

Kayley found the keyboard again with her free hand and typed, I want to make u cum, squeezing him tightly and giving his cock a full stroke. Mr. Radley's eyes widened and he bit his lip, before managing to say, "Good job, Kayley. You've really... improved."

Her teacher reached out, typed, What are you waiting for then?

It was all the permission Kayley needed. She pulled his underwear down as far as she could, freeing almost the entire length of him. Now they were both in uncharted territory, his cock throbbing in her fist, plainly visible to anyone who so much as stood up and turned around. Maybe he could pull his shirt over before anyone realized what was happening. Probably not. Mr. Radley realized he didn't care overmuch, the sensation of her hand gliding up and down overriding any sense of caution.

This girl, he thought, my god, this girl.

Even though they'd only been together twice, Kayley could tell when her teacher's orgasm was imminent. Even now, with the class in front of them and his mouth pressed into an expressionless line, she could see it in the flush of his face and the way the corners of his eyes tightened. A quick caress of his balls found them high and tight; she let her hand linger, carefully squeezing them. He exhaled sharply, typed, I'm close.
