It wasn't until she was driving home that the enormity of what had happened- what she had agreed to let happen- hit Kayley. She had cheated on Travis with Mr. Radley. Let him fuck her tits, her mouth, cum all over her. Lost in the moment, she had masturbated for him while he recorded. And she was going to do it again.

All for a grade.

She didn't know whether to laugh or cry. Her hands trembled on the steering wheel. She should have known that it would take more than a little cleavage to bring her grade up, but sex? Sex behind her boyfriend's back? In the moment, with Mr. Radley's tongue in her pussy, it seemed so reasonable, a good idea even. He knew how to make a girl feel amazing. Now, the school miles behind her, unread texts from Travis on her phone, Kayley was having second thoughts. Could she go through with this six more times? He'd told her to meet him tomorrow during P.E. Stomach twisting in knots, she wondered what he had planned.

"Anything," he'd made her promise, Kayley's mind spun with all the potential meanings of that word. Shame and excitement filled her in equal measure.

Her teacher's semen had dried to a thin crust on her belly, thighs, breasts. Everytime she shifted in her seat, she could feel it flaking off inside her clothes. His salty taste lingered on her tongue. She needed a shower. Kayley sucked in a deep breath and pressed down on the accelerator, eager to get home.

Pulling up to the split level duplex where she'd lived her whole life, she saw that her parents weren't back from work yet. Thank God. Kayley didn't want to explain her messy hair, or why she took the stairs two at a time up to her bathroom. She stripped quickly, pausing only to look at the tank top that had started this entire mess. Did she want to keep it? She looked good in it, but it wasn't her.

Oh? And is having your teacher's cock between your tits you? she couldn't help but think. Is licking his cum off your fingers you?

Kayley tossed the tanktop into her hamper. She'd decide later. Right now, a hot shower and a bar of soap were calling her name, something to scrub off those scaly white patches that dotted her skin. The water hit the tub with a sputtering hiss, the room quickly filling with steam. She let out a long sigh, and stepped into the hot water.

***

Travis was waiting for her in the parking lot the next day, decked out in his usual red plaid pajama pants and Supreme hoodie, his straw-blonde hair tucked under a ballcap. Kayley's stomach did a flip at the sight of him, yet she still managed a big smile and a quick peck on the lips for her boyfriend. She'd gone back to her usual modest attire: A school sweatshirt and baggy jeans, underneath which was a sports bra and bikini-cut white panties.

"Hey," Travis said, "how come you didn't text me back last night?"

"Sorry baby. Too much make-up work. I went to bed early." She took his hand in hers as they walked toward the building. If he noticed how slick from nervousness her palms were, he didn't say anything. The truth was, everytime she opened her messages and started to respond, her mind emptied of everything that wasn't Mr. Radley's hands, his tongue. Try as she might to type out a few simple words, she could only remember how it had felt when he thrust into her mouth. So she had gone to sleep without answering, waking up halfway through the night frowzy with half-remembered dreams of heat and flesh that left her panties wet.

"Yeah? How's that going? You talk to Mr. Radley yet?"

At that, Kayley burst into a fit of anxious laughter, loud enough her boyfriend gave her a look. She reeled in her emotions, squeaked out, "He couldn't meet yesterday. He's going to come get me during P.E. Said we'll figure out a plan."

"You think you're gonna graduate?" Travis said, relief audible in his voice.

"Yeah," Kayley filled the word with as much excitement as she could muster. Each step she took by Travis's side was an agony of guilt. Not just for the cheating, but for how much she enjoyed it. Couldn't help but steal glances at her boyfriend's crotch, mentally compare his cock versus Mr. Radley's. Was her teacher going to fuck her today? There was a twinge between her legs at the thought.

"... this Friday?" Travis was saying, snapping her back into their conversation.

"Sorry, what?" she said, shoving those lewd thoughts away.

There was a note of exasperation in Travis's voice when he replied, "I was asking if you wanted to go to the movies Friday."

Friday. Yes. Day after tomorrow. She was free. Kayley told her boyfriend as much, was gratified to see him smile, even as it twisted the knife. She pecked him on the cheek, made noises about how much she was looking forward to it.

They reached her first period classroom, senior Chem with Ms. Lauvier. Travis kissed her, saying as he left, "See you in P.E."

Kayley felt the blood drop from her face. P.E. Mr. Radley was coming for her that period. She'd be walking off to do who knew what with the man right in front of Travis. Oh God. What if Travis suspected something? What if he followed and saw... saw whatever their teacher was going to do to her? All the good grades in the world wouldn't matter if he dumped her. So preoccupied,, she shuffled to her seat, got out her things. She said hi to other students, followed Ms. Lauvier's instructions, and when the bell rang she couldn't recall a single word of the lesson.

Travis had first period on the opposite side of the school, so she thankfully didn't see him before ducking into the locker room to dress down. A small mercy. Of course, he'd be in the gym. No way to avoid him there. She hoped Mr. Radley would snag her before then. She wasn't sure she'd be able to follow through on the deal with her boyfriend right there.

Mr. Radley...

Almost ill from nervousness, she snuck glances at herself in the mirror as she changed, trying to see how she would look to him. No makeup today, not even lip gloss. Hair done in a ponytail high on the back of her head. The sports bra strapped her tits down, making them look a cup size smaller. The panties, cut high at the hip, accentuated her legs, lifted her ass just a little bit. I look alright, Kayley thought as she pulled on the gray school P.E. shirt and loose basketball shorts, blinked at the realization that she hoped Mr. Radley thought the same.

***

Mr. Radley made his way down to the gym right after the bell rang. He took his time, chatting with students as he went, his casual bearing a lie to cover up his growing anticipation. He'd hardly been able to focus during first period, zoning out while the class plugged away at an essay, mind occupied with the welter of possibilities his upcoming time with Kayley offered. How far could he push her? Hopefully, yesterday hadn't been a fluke. It would be disappointing, though not entirely unexpected, if she got the jitters and backed out of the deal. It had happened once before, with a girl who had agreed to pose for some intimate shots in exchange for a recommendation. He'd only forestalled her turning him in by deleting all of the photos as she watched. Mr. Radley was pretty confident that Kayley wasn't going to get cold feet. He'd seen her face- this girl was horny and desperate, and he could meet both of those needs better than her shitty boyfriend ever could.

The question of what he would have his student do occupied him all the way to the gym. Something different than yesterday, probably, though he hoped he'd have the opportunity to fuck her tits again before this was over. They were too good not to put his cock between. Hmmm. Kayley mentioned that her boyfriend didn't like blowjobs. Judging by her enthusiastic performance, she certainly did. Maybe he would begin there.

The thunder of rubber on polished wood enveloped Mr. Radley as he stepped into the gym. One group of students did laps around the perimeter, while another was warming up with stretches in the middle. He quickly spotted Kayley, slowly jogging along beside Travis on the far side of the room. The boy was talking, gesturing broadly with both hands. Kayley was looking everywhere but at him, her mouth pressed into a thin line. Their eyes met across the gym, and Mr. Radley raised a hand to beckon her over. She flushed, glanced quickly at her boyfriend and then back at him. Said something to Travis, and began making her way over.

As she approached, John Elston, one of the P.E. teachers, sidled on up. He was the only other person who knew about Mr. Radley's special accommodations for female students, had known ever since the latter man had walked in on him railing the class president in the locker room two years ago. Since then, they covered for each other, occasionally sharing an amenable girl between them, like with the aforementioned class president, a gorgeous black girl who they'd had a lot of fun double-teaming multiple times.

"What's up, Ethan?" Mr. Elston asked. He had a smooth voice that he loved to say the filthiest things to girls with.

Mr. Radley gave him a grin, said, "Kayley Banks needs a little extra help with English. Mind if I borrow her for a bit?"

Mr. Elston raised his eyebrows. He knew the look. "Kayley? Her?"

"I know, right? I was surprised too."

Mr. Elston ran a hand through his close-cropped hair, let out a low whistle. "I'm not using the storeroom this period. Wanna go there?"

"Yeah, thanks, man," Mr. Radley replied as Kayley came to stand by them. He turned to the girl. She was glancing over her shoulder. Following her gaze, he saw she was looking at Travis. He and the boy locked eyes for a moment, before Mr. Radley turned away without acknowledging him. "Hey Kayley, come with me."

Kayley felt Travis boring holes into her back as she went to follow her teacher. She resisted the urge to look back at him again, not confident she'd be able to hide the complicated swirl of emotions whipping through her. She'd barely been able to talk as they did the warmups. Thankfully, he'd done enough talking for the both of them. She glanced at Mr. Elston as she passed; he gave her a smile so perfectly neutral he had to know what was up.

No, she thought, I'm just being paranoid. She hustled to catch Mr. Radley, briefly confused when he led her over to the metal storeroom doors tucked along one wall of the gym.

"I thought we were going to your room," she said, raising her voice to be heard above the sound of students running.

Fishing a ring of keys from one packet, he unlocked the door, reached in to flip on the lights.

"Too long of a walk. I want to make sure we have enough time to do what we need to do." He held the door open for her. Breathing in deep through her nose, Kayley stepped past, trying not to think about the fact that an entire gym full of her classmates knew where she was going with Mr. Radley. Knew where she would be while he had his way with her. She peered around the storeroom, took in the stacks of gym mats, the cages full of basketballs. The space smelled like rubber, shadows deep and liquid beneath the sputtering overheads. She jumped a little as the door shut behind her, the sound of her classmates' feet reduced to a palpable vibration.

"W-what are we going to do?" she asked as Mr. Radley stepped around her, his hand grazing her ass as he went. He sat down on a stack of mats, his back to the door. He patted the spot next to him; obediently she hastened over and plopped down. Their shoulders brushed; despite yesterday's intimacy she couldn't help shift so she was sitting at an angle to her teacher. Their knees, his clothed in black denim, hers bare and pimpled with gooseflesh, bumped.

"You said your boyfriend doesn't like blowjobs?" Mr. Radley said.

Kayley blinked in surprise at the question, at the mention of her boyfriend, at the complete lack of preamble. Remembered the look on Travis's face when she had tried to suck his cock, lean features screwed up in disgust. Then she remembered Mr. Radley's expression yesterday afternoon, when her lips had been wrapped around his shaft: Pleased, mouth slightly open, eyes meeting hers. As if on cue, her pussy clenched, and she felt a fresh wetness there.

"No, he thinks it's dirty," she said. Kayley could feel her cheeks warm, wondered how she could still be embarrassed by anything with this man.

"Huh," Mr. Radley said, "There's something wrong with the world when teen boys don't like head. How many times have you sucked cock?"

"Twice."

"Counting yesterday?" his voice was lightly disbelieving.

"Yeah. Is that weird?" Kayley twisted her hands in her lap. Mr. Radley reached over, gently pried them apart. Put his hand over hers on her thigh.

"It's not weird. Did you like doing it?"

"I did," Kayley admitted, surprised at how steady her voice was. She glanced at his crotch. The lights were low enough that she couldn't tell if he was hard or not. She suspected he was. A sudden forthrightness seized her, and she said, "Do you want me to suck your cock, Mr. Radley?"

He chuckled. "Yeah. Do you want to?"

She paused. Dug down through the shame and the guilt, past the part of her imagining Travis standing with his ear to the storeroom door, hearing everything. Did she want to do that again? The answer, as it had been yesterday, was easy to find.

"Y-yeah," she blushed, looking away. The hand on her thigh drifted under the hem of her shorts.

"Is that all you want to do?" His fingers slid further, closing in on where hip and thigh met. Kayley's heart thundered. She froze, lips parted. No, she didn't just want to go down on him. The words boiled at the back of her mouth, her brain scrambled by the potent mix of desire and shame.

For his part, Mr. Radley was calm. She wanted more, he could tell. Didn't want to spook her. It was a risk, he knew, doing this so close to other students, to her boyfriend. A hand on the door latch, a basketball slamming against the wall; any of that could shock her out of the mood he was carefully building. He could feel her rapid pulse through the skin of her leg, the heat emanating from her pussy. He raised his free hand to her chin, turned her to face him. Her eyes were wide and white in the gloom. Nervously, she licked her lips. He leaned in, kissed her gently, moved along her jawline to her ear, where he nibbled on the lobe. She shivered.

"What do you want?" he whispered.

"I want you to fuck me," Kayley finally admitted. At those words, she felt a kind of release deep within her, as if saying it aloud made all of this okay. He'd already been in her mouth. How did this change anything?

"Yeah? You want me to fuck you here, with all your classmates outside?" He didn't mention Travis this time, she noticed, but his name was there, unspoken. In all of her fantasies, fucking on a pile of gym mats had never come up, not with her boyfriend or anyone else. Certainly not her English teacher. Nor had doing it with half the senior class ten feet away. But now that they were here, his heat against her, his fingertips brushing against the hem of her panties, she began to understand that this was hot because of those things, not in spite of them. The risk of someone seeing her here, with him.

This is a risk for both of us, Kayley realized. At that, she took him by the wrist, pulled his hand off her thigh and slid it down the front of her shorts. His fingers found her cleft, shielded in damp cotton, and pressed down and in. She shivered.

"I want you to fuck me right here," she said.

"Good," he replied, "Now take these off." He pulled her shorts down, forcing her to awkwardly lift up her butt and then legs to let them drop to the floor. She started to pull off her P.E. shirt, but he stopped her.

"It's got the school logo on it," he explained, standing, "it's hotter that way."

As his crotch drew level with her face, Kayley could see how the fabric bulged out. Suddenly eager, she undid his belt, button, and zipper, revealing the underside of his cock, thick through the fabric of his boxer briefs. She ran a fingertip down its length, enjoying the way he twitched. Feeling bold, she leaned in and mouthed him.

"What do you want me to do?" she asked, lips vibrating along his length. Mr. Radley stared down at his student, delighted that he had read her correctly. He worked his pants and briefs down, freeing his cock. Using her pony tail for a handle, he rubbed her face against it, dragged its length from cheek to cheek, up to her forehead and down to those waiting lips, pursed and wet. Her pink tongue washed his glans, occasionally sucking gently. He resisted the urge to push her head down hard.

Not yet.

"What do you want me to do?" Kayley asked again, cupping his balls. Her eyes were wide, breath heavy as she traced a finger up and down the underside of his cock..

"I want," he said, "you to do to me what you'd do to your boyfriend if he liked blowjobs."

Until Mr. Radley said that, Kayley hadn't hated any part of this. Sure, she'd wanted to hate it, and it was embarrassing and awkward and awful, but she didn't hate it. There was no denying that. Now, however, she found something to hate, something that infuriated her and almost made her stop.

Kayley hated how wet she got at those words. Hated the accompanying realization that as guilty as she felt, as ashamed as she felt, she enjoyed cheating on Travis. Not just for how good Mr. Radley was, but for how wrong the entire situation was. She was fucking her teacher for a grade, cheating on her boyfriend, and her panties were soaked through.

So, hating this, hating herself, Kayley wrapped her fingers around the base of his cock, brought her other hand to the back of his leg. Slowly, so slowly, she took him into her mouth, deep, the taste of him coating her tongue, until she felt him hit her throat. She drew back, slowly, so slowly, hand following to stroke as she sucked. Then again, faster. Again, faster, saliva dripping, embarrassingly loud slurping noises following each repetition, fingers and lips forming a seal around his cock. Mr. Radley moaned, thrusting his hips in counterpoint to her rhythm. She looked up at him, loving and hating the lustful way he met her eyes. A darker urge seized her, a strange desire for punishment. She shouldn't get to enjoy this too much.

Kayley took her mouth away, still watching her teacher's face, excited for and afraid of how her next words would change his expression.

"Fuck my face, Mr. Radley," she panted. She wanted this. She didn't want this. What did he want? His face said it all, mouth spreading into a lascivious grin, eyes glittering slits.

"You are just full of surprises," he murmured, almost to himself, gripping her ponytail in his fist. She gasped softly at the sudden pain in her scalp, silently cursing how hard it made her nipples. Travis was rough sometimes, but it was, she understood now, a lack of skill, not a conscious choice on his part. Mr. Radley knew exactly what he was doing as he pressed her against him, cock hard between her cheek and his lower abdomen, tugging lightly until her lips split against the underside. She let her tongue caress his cock as he pulled her higher, until her mouth was poised at the tip, open and straining for him like a baby bird.

I deserve this, Kayley thought as he forced her head down, his cock filling her mouth, going into her throat, held it there while her eyes watered and she reached the cusp of gagging. Then he pulled her back, let her catch a breath before pushing her down once more.

Tears slid down Kayley's cheeks. She hated this. She loved this. She wanted to swallow Mr. Radley's entire cock. She tried, oh she tried, wriggling her head in a futile attempt to break past her gag reflex, feeling relief and disappointment every time he made her come up for air.
