Teacher's Favorite Day

Grace cut through the water blissfully unaware of the eyes feasting on her bare bottom. The teacher's long dark hair flowed out behind her as she swam, her mind drifting pleasantly. This was her guiltiest pleasure, her naughtiest secret, and her favorite day.

Nude Day.

Every year now since she came to teach PE at Clefthill High, she snuck into the swimming annex and made this her Nude Day tradition. It was relatively safe. A group did water aerobics and there were swim lessons in the mornings, but by the afternoon, the place was locked up again, with only the other PE teachers and the janitors having keys. Of course, there was always the chance one of them could walk in, but the risk made the act all the more delicious.

Except now.

Eighteen-year-old freshly graduated Charlie gaped down at the naked woman and her perfect form as she swam through the water. Her ass was perfect, nice and juicy on her petite frame, and any time she rose up with her strokes, he could see the sides of her big breasts. Whoever she was, he didn't think she was a student, though he couldn't see her face.

"Holy shit," he whispered to himself, his cock rising in his swimming trunks.

Like her, he wasn't supposed to be there, but his father was a maintenance man for the school, and one of his duties was upkeep of the pool. Knowing that Charlie was trying to make an effort to keep the pounds off before college, he loaned his son a key to the place so Charlie could get in some laps in private.

And now here he was, staring at a completely nude woman in the school's pool, a beach towel neatly folded by the stairs leading into the water but not a stitch of clothing in sight other than that.

Too late, Charlie realized he was about to be discovered. She reached for the wall, spun, and kicked off again, her head rising. She reached out as if to start her strokes again, but before she made it more than a few feet, she floundered in the water, covering her breasts and straightening up, yelping, "Oh my God, oh shit!"

"Oh shit!" Charlie echoed, gaping at his fantastically nude dream woman.

His PE teacher, Ms. Grace Chen.

* * * * *

She pressed her body as close to the wall as possible. "Charlie, I... I..."

The eighteen-year-old had her flummoxed, and not just because she'd been caught by a former student, which could lead to potentially serious ramifications to her job. He was erect, his bulge standing tall in his blue swimming shorts. Very tall. Very fucking tall. Even as she wanted to die of embarrassment, she wanted to giggle too. When the young women in his life found out his secret, she doubted geeky Charlie was ever going to spend a Saturday alone again.

And he was a geek, but he also had her respect. She helped coach practices for the track team the year before, and Charlie, a senior, worked his ass off to some great gains. He wasn't quite fit enough to place often in his events, but if he kept slimming down and toning up, he might make it as a walk-on to his college team.

With his extra flab all but gone, Charlie approached a certain sort of youthful charm. His frizzy hair could use a trim, but his slim, long face, strong chin, and bedroom eyes would serve him well if he could ever work up the courage to ask a girl out. She would bet good money her ass and tits were the first he'd ever seen in real life. Not that there was anything wrong with that. She was older than him when she lost her virginity. But still, the idea that she had given him the thrill of his young lifetime amused her.

"I'm sorry, Ms. Chen. I didn't know, um, um, that anyone was in here. And I didn't expect..." He swallowed, his eyes roaming what little he could see of her. "...you know, um... you."

"What are you doing here?" she asked.

"My dad works for the school and takes care of this pool. That rhymes," he said, smiling weakly and looking like he might faint. "I... I come in here to exercise because Coach said swimming was really good cardio and it's my favorite way to exercise and... um... but what are you doing in here? No one's supposed to be here."

"Yeah, we're both kind of breaking the rules, aren't we?" she asked.

"You think?"

That made her laugh softly. "The truth?"

"Sure."

"Today is Nude Day. It was my favorite day in college. My roommate taught me about it, and every year, we did something dumb to celebrate it. Like we'd streak across the quad, or flash our professors or something."

"Holy shit," Charlie breathed.

"Well, okay, I had my bra on for that one but she went totally topless for it." Grace fought the urge to giggle like some brainless ditz, thinking about how wild they got. She and that same roommate had once held hands back to back as they blew six of the football team. Another time, their boyfriends took turns fucking their asses. God, she was getting turned on by this, the thrill of being caught by a student making her want to rub her thighs together.

"So... you do this because of Nude Day?" Charlie asked.

"Wh.... oh. I trailed off. Sorry." Grace unconsciously moved away from the wall, just by inches, but it was enough to show off even more of her big breasts. "Yeah. It's just a little bit of fun. I come in here every year and swim a few laps naked. It..."...excites me, she thought but didn't say. Despite the cool water against her skin, she felt flushed, and finally she was aware of her tits nearly above water, her big dark nipples visible under the surface. "Oops."

"I... I won't tell."

Grace expected a "if you let me see you naked" or "if you blow me or fuck me" but Charlie didn't say any of those things. He just stared, his hands twitching against his hips as though he wanted to jerk his big cock.

"Thank you," she murmured. "I'd better get out now."

"Oh, uh, I'll turn around, or, or, or go in the men's locker room or..."

Grace thought about it. Despite his words, that he would tell his friends was a certainty. He might be eighteen and soon to be a college freshman, but he was still a teenager and she had no doubt he wouldn't last the night before he was on the phone with his two best friends telling them about seeing their hottest teacher naked. But there was no way in hell they would believe him, and even if they did, who in turn would believe the three of them?

"You've already seen most of me anyways, Charlie. Might as well get the whole show... if you won't tell anyone?" she asked, pouting her lips. She knew the power those lips had. Her slim hips, tight athletic ass, and big breasts had a lot of power, but it was her face that ruled over men, her big doe eyes, her dark lashes and thick eyebrows, her pouty full lips, her delicate features. Her PE classes were always filled with guys looking to ogle her all year long.

"I... I won't tell," Charlie said. "Are you really going to let me see you, uh...?"

"Naked?" she asked. She moved back towards the wall and held up a hand. "Help me?"

"Holy shit," Charlie squeaked. He gripped her by the forearm, and as she pushed upward, he pulled, bringing her up and out of the pool. Water cascaded down her body, gleaming on her curvy breasts and her taut thighs. He gaped at the thin strip of black pubic hair leading to her thick pink pussy lips. His huge eyes slowly moved upward across her body, at her pubic mound, her trim belly, her big breasts with the slightly upturned nipples. These he stared at for a long, long time, and Grace found she did not mind, not one bit, her chest rising and falling, her need starting to burn inside her.

So when the eighteen-year-old moved towards her haltingly, she moved for him too, hand going to his cock through his shorts, her other on his chest, not quite lean but definitely getting there. He whispered it one more time -- "Holy-" -- before her lips met his, tongue sliding between his lips.

Charlie froze, his eyes huge, his hands and arms stiff at his sides. If he even breathed, she wasn't aware of it. She took the initiative, moving her hands to his and bringing one around to her ass and the other to one of her breasts. He gave her tit a tentative squeeze, and moaned, "So soft, and... and..."

"Shut up and kiss me," she growled, and her student did just that. Instinct took over for the eighteen-year-old and his hands began to work in earnest, roaming her breast, squeezing her ass and pulling his hot teacher against him. His cock was pinned between them between their bellies, his hips beginning to rock upward like he was trying to fuck her stomach.

His kisses were overeager and unpracticed, but some other woman could teach him how to do it properly. She wanted him like this, raw, inexperienced, ready to fucking explode from her touches. It was undeniably hot to have a virgin melting at her fingertips, a former student of hers, so fucking taboo she would be thrown out of her job and the community if anyone could ever prove this. It was dangerous, but on this day of all days, she wanted it to be that way.

Slowly she began sidestepping with him, feeling with her foot both for the edge of the pool and her towel. She brushed up against the material and broke away from Charlie, his lips still trying to chase hers.

"Stay right there, just like that," Grace said.

"But..."

"Trust me."

Charlie stared as she snatched up the towel and folded it on the ground in front of him. Grace dropped to her knees slowly onto it, tossing back her wet hair and grinning up at him as she hooked his waistband with her fingertips. When she tugged down his shorts, his cock sprang out as if to say hello, and she greeted it in kind, pinning it against his stomach again and giving his base a nice, long kiss.

"Oh shit, Ms. Chen!"

She gripped the base of his shaft with both hands. He was remarkably big, and her moan of pleasure as she licked up his precome was genuine. "Warn me when you're going to come," she murmured.

He swallowed and nodded fervently, drawing another sultry laugh from her. Her lips wrapped around his tip, and she thought he might come right then and there the way his knees went weak. But Charlie held on, and moaned, "Oh God," as she took him deeper, staring up at her student. As her mouth descend on him, she worked his base with her tongue, what little room she had to work with. She came up off him with a slurp, her mouth filled with saliva. She pulled his cock down so she could spit on it, getting it nice and slick for her hands.

With that, Grace really got the blowjob going. Her slim hands worked up and down his length as she stuffed her mouth with as much of him as she could, her jaw pushed lower and lower as she swallowed inch after inch of him. Whoever he fucked later in life, he would always have to measure them up against this blowjob, she vowed to herself.

The thought excited her and she squeezed her thighs together. She wanted to rub her pussy but there was a job to do here and she wanted his come right the fuck then and there. Her hands whirred up and down his length as she began to bob harder on him, liking the saltiness of him, the scent of his Irish Spring still fresh on his skin. His pubic hair was wild and untrimmed, but her hands kept it pushed away from her mouth.

"Oh, oh wow, that feels good, that feels so good," he said.

His hands went to her head by instinct. "Mm hm," she moaned around him, wanting to tell him to grip the back of her head, to use her mouth, to fuck her face. She could do none of that, not with him keeping her in place as his hips began to work back and forth, meeting her mouth, her tongue. "Urk urk urk!"

He jerked back, his hands letting go of her head. He gasped, "I'm sorry, I shouldn't have, I didn't mean to choke you."

She came off him with a gasp. "I fucking love it, Charlie. Keep fucking my face, keep using me like that."

He gaped at her, as she spat on his dick again, then when she devoured him, he dropped his hands back on her head and began pumping his hips back and forth. Like his kisses, he had no control. He hit the back of her throat over and over and over again. She'd be sore from this, but oh God, it was so hot, so fucking hot, and she couldn't help herself now, jacking him faster and faster, desperate for his come even as her eyes watered and her jaw ached.

"Ms. Chen, oh God, oh fuck, I'm going to come, I... oh, shit!"

His come rocketed out of him, but instead of stilling, he bucked even harder. She tried to swallow but she couldn't, not with the force of his face-fucking. He nearly sent her falling backwards, pushing up on her and down at an angle, his big cock invading her mouth, punching in and out with a ferocity she'd never felt from any other man, and she loved it. He fucked her mouth so hard some of his come flew out of her mouth with her spittle, coating her chin and spattering on the floor.

Finally he pulled back, gasping for air, and she coughed out a mouthful of come, dropping one hand on the ground and staring at the tile.

"Are you okay?' he asked timidly.

She finally looked up at him, blinking away tears from the lack of oxygen moments ago. Her jaw and throat ached, but she croaked out, "The locker room. Now."

* * * * *

Charlie couldn't believe his luck even as the sexiest teacher in Clefthill High walked him into the locker room, her tight ass swishing back and forth as she strutted like a runway model. Several times she looked over her shoulder at him, a dazzling smile showing off her gleaming white teeth. There was come still drying on her chin and breasts, and the image was going to make him hard again in no time

Her clothes were neatly folded and resting on top of one of the benches. Here she stopped, tugging his shirt up and over his head and helping him out of his shorts. He couldn't keep his hands off her tits, and she giggled throatily as he played with her nipples.

"Come on, stud. Lay on that bench over there," she said.

Stud? Him? He was still so damn sure this was all a joke, or a dream, or a prank. But no, it was real, and when he situated himself on his back, his teacher lifted one leg up and over his head and straddled his face. He was about to get his first taste of pussy, and it was with a thirty-something teacher.

"What do I do?' he asked weakly.

"Just stick that tongue out and start licking like crazy," she said. "Don't worry. I'm going to ride that handsome face and take care of myself."

She dropped down onto his face, grinding her pussy against his lips and chin. Ms. Chen tasted like chlorine and the pool, but Charlie gave zero shits about that. What held his fascination beyond the fact that his teacher -- his fucking teacher! -- was riding his face was that his nose was pressed basically against her bud. That might have grossed some guys out, but he sort of liked it and wondered what she would do if he licked her ass. It was dirty, but she had a really hot ass.

Like she told him, he started licking everything his tongue could reach. His hands went around her and ran up and down her ass, taking in the taut muscles and springiness of her body. She was in crazy good shape, not ripped or anything, but slim and soft all at once. Every straight guy in school drooled after her, and here she was, her pussy leaving wet trails on his face.

He wondered if he was doing this the right way, but Ms. Chen's moan assuaged his fears. "That's it, that's it, you fucking stud."

There was that word again, and it sent a thrill of pleasure up and down his spine. He was driving his teacher wild. That was fucking crazy but it seemed to be true.

"Such a big cock, when they find out about you, oh my God, Charlie." She ground on him faster. He wondered if anyone had ever died from pussy asphyxiation, then decided if he was the first, it would at leas make him a legend at school. He could live with that.

"Mmm," he said against her wet folds, his tongue spearing into her deep.

"Feel, ah, feel how wet my pussy is for you?" she asked, her voice going higher in pitch. He did, and tried his best to nod or acknowledge her, but she kept her pussy locked to his mouth and his chin, her hands idly running up and down his stomach. "You're doing that to me, Charlie, your teacher, mm, the only o-one of my students to have ever... ever done this to me, oh, oh fuck..."

Oh shit, oh shit, that was hot. He clenched her ass harder as her hands moved to his cock.

"Oh my, getting hard again already? Naughty boy, Charlie. But good thing. My mouth needed something to do again."

"Oh fuck," he managed to gurgle out, then she was driving back down on his face, rocking harder, nearly bouncing on him. Her weight shifted on him as she leaned forward, fingers running up and down his length before her warm, wet lips enveloped him again. Before, he was embarrassed at how quickly he came in her mouth but now he knew he could last a long, long time. He liked to practice at home, edging himself for upwards of an hour, sometimes even longer. When he'd come, it was like a fucking cannon, sometimes even hitting his chest.

"That's it, that's it," she moaned around his tip, and swallowed him back down again. When she came back up, she added, "Get hard again for me, then you can fuck me, baby, you can fuck your slutty teacher."

He clutched at her ass, his mind whirling. Nick and Chase were going to flip out when they heard his story. He was fucking a teacher. And not just any teacher, but Ms. Chen. He probably shouldn't tell them, right? But... but they wouldn't tell anyone, would they? They were his best friends, and he HAD to tell someone.

Whatever. That was a concern for later. For now he was getting another wild blowjob while he was eating his PE teacher out.

"Ohhhh, ohhh, that's it, mmm, I'm so close, I'm going to come for you, Charlie," she cooed against his cock, rubbing it now against her face as she rocked harder and harder. She moved forward too far, coming free of his mouth and lips, but it gave him a chance to do what he wanted to try, and he grabbed her ass to give it a long lick, from the top to her bud. He thought he'd gone too far when she froze up, but then her wail proved him wrong. "Ohhhhh, fuck! Fuck... fucking lick my ass, lick my... ahhhhhhhh, Char-lieeeee!"

She came, and Charlie deliriously kept licking, rimming her tight little asshole. Finally she shoved off him and gasped, "Stay right there." Ms. Chen spun around and straddled him again, this time right above his cock. She gripped him and pointed him upwards, her dark, usually amused eyes wild with desire. He'd never seen a woman look like this, not even in the best porn films. She looked almost feral, and it was stupid hot.

"We can't tell anyone about this," she said, and he nodded frantically. In that moment he'd have agreed to just about anything she asked him. She positioned his cock against her entrance. "This is crazy, this is crazy, this is crazy..."

"I'm a virgin," he said weakly.

Ms. Chen's already lust-crazed smile grew even wider. "Not anymore," she said, and dropped on his dick.

* * * * *

Grace raked her fingers across the young hung stud's chest as he stared up at her adoringly. She barely noticed any other part of him but his cock in that moment and for long minutes to come. It had been years since she was stuffed this well, nearly a decade, and she savored it, his thickness hitting her spot just right. Her pussy walls contracted around him trying to grip him like a fist, willing his come inside her. Dazedly she tried to remember when the last time she took the pill was. Her date last Saturday? It'd probably be fine if her student came inside her, right? Her donkey-dicked student? The student who just made her come so hard she nearly fainted?

"...donkey... dicked... stu..." Grace moaned. And with that, she fucked him.

There was no holding back for either of them. No control. He let her do the work, pawing at her tits and her ass, his eyes huge and never seeming to blink. Grace rode him as hard as she'd ever fucked anybody, hips slamming down, her skin slapping against his. Her hands went everywhere, across his chest, his abs, her stomach, her clit, her mound. Every inch of her skin in that moment was an erogenous zone and the pleasure right from the start was almost enough to make her scream.
