The Instructress

"Hi," Sam called as he strode confidently into the hall, "Is the teacher here yet?"

Donna looked up irritably and tightened the black belt that wrapped around her white martial arts kimono. She flicked her long blonde hair over her shoulder and slipped on a hair elastic, "She is," she snapped.

Donna was almost six-foot-tall and weighed seventy-five kilograms. Now in her mid-twenties, she loved anything that used her natural strength and agility; immersing herself in everything from yoga to martial arts.

Her glare softened slightly as the guy smiled and lined up in front of her. At least she had one student show up for her first class. Tall, slim and attractive, he had the look of a model with a gym toned body, and the relaxed confidence that she had never had.

"Okay, let's go," he smiled.

She felt a pickle run up her spine. She was the instructor; this was her class.

The overconfident man followed her warmup routine, but when his first press up didn't touch the mat, Donna placed a bare foot on his shoulder and pressed down.

"Hey, that's not fair," Sam grinned from the mat.

"Well, neither is this..." her words drifted away as she sat on his back and pulled his arms up behind his back and trapped them between her thighs.

"Okay," Sam panted, the weight of the woman heavy on his back and his arms completely jammed.

"Okay? The only way out of a lotus lock is to part my legs with your twisted arms. Think you can do that?"

"Sure."

Donna rolled her big brown eyes, enjoying the satisfying moans from below as she easily squeezed her legs together with Sam's arms still wedged between.

As a kid she had always had a temper and standing out as being taller and stronger had made it worse. Cute boys at school, and now cute men like Sam, had always found her too intense and intimidating. Fuck. She had known Sam for less than ten minutes and already he was moaning in pain beneath her. She composed herself, gently released her hold and placed his arms back on the mat.

*

The following week Sam arrived to find Donna stretching on the mats wearing only short red gym shorts and a white tee-shirt. She looked around in surprise, "Oh, I didn't think you were coming," she said springing back to her feet and into an instinctive fighting pose "I'm not dressed..."

"It looks cool."

"Yes, its but not appropriate for some hold," she tugged self-consciously at the shorts that barely covered her bottom. Despite her athletic physique, she had long since convinced herself that men did not find her attractive.

"Presumptuous of you. This week I may win.

Donna smiled, annoyed with herself for liking this guy.

As before, the warmup left Sam exhausted and he was breathing hard as they started to spar. Despite the newly leant evasion techniques, Donna quickly caught his wrist and twisted until she had Sam on his knees. She stepped over his shoulder so that his arm was caught between her legs and his head was bowed down level with her calf.

"You must watch for the wrist," Donna coached, "otherwise you'll be a whole world of pain."

She caught herself smiling again at the prostrate man moaning beneath her. This was fun. She knew the next move was cruel and would completely incapacitate him, but she couldn't help herself as she slowly dropped to one knee.

With Sam's shoulder at the end of its range of movement and with Donna's weight on his shoulder he was helpless to stop her taking him to the mat. She controlled him carefully until he was now lying with his arm held awkwardly above him and his head resting in the fold between her thigh and her calf.

His panting breath against her leg was making her tingle. It had been too long since she had been this close to a man, and his moans of pain seemed strangely erotic.

"So, let's talk through the evasion techniques again," Donna breathed calmly, in no hurry to return his freedom.

"While I'm like this?" Sam panted.

"Yes," Donna breathed, "or next time, your opponent might do this."Controlling her breath, she slowly sat back on her haunches, her butt crushing down on to Sam's head.

Her shorts were sitting on the side of his head and while Donna's hold didn't hurt, it was totally immobilising and humiliating. With the intransigent woman refusing to release him, Sam had no choice but to try to remember what she had taught him, his words muffled by the back of her leg.

"And what else?" she asked, looking down to check that her victim had not succumbed to the crushing force of her thigh. Sam continued.

"Good," she smiled, impressed that Sam had listened to her, "and now you also know why it's so important," she allowed herself to smile again, "cos it's not easy to get out once I slip you into this."

"It's impossible," Sam moaned, breathing hard under her unyielding pressure.

"Mmm... and if I wasn't a nice girl, I could snap your arm or crush you... or even fart in your face."

Sam didn't dare move. The woman's hold gave him only one position that wasn't excruciatingly painful and that position was bowing prostrate on the floor beneath her.

"Give up?" Donna breathed.

"No..."

Donna was tingling with arousal, her captive man trapped down between her legs. She sat back on his head with more weight until her red shorts moulded around his head, his gorgeous features now contorted down in the nether regions of her lusting body. She studied their joined reflection in the mirror and from her angle, it looked as though her body had devoured his head. She felt like a goddess who had conquered her nemesis and she freed her blonde hair from its elastic to complete the look.

Neither spoke as Donna held Sam beneath her, a certain sexual tension in the silent hall. Donna sighed, the temptation to thrust down thymically on to his head was becoming uncontrollably, and so she reluctantly released her student's arm and stood up leaving the cute but crumpled man to climb to his knees.

"Again?" Sam panted, still on all fours.

Donna found herself grinning back, "Really? Next time I might keep you..."

Intrigued by what she meant by this, Sam climbed to his feet, ready to start again.

He started well but less than a minute later found himself on his back and seconds after that, Donna's legs appeared behind him. She forced his neck into the V of her crotch and slipped on a figure 4 headlock. Her thighs closed around his neck, her left leg tucked tightly under her right thigh and pulled into her side to lock her lower body in place.

"You don't want to get caught between my thunder thighs," Donna puffed, reliving a painful insult that others had used on her.

"Your thighs..." Sam tried to reply but was cut off in mid-gasp as Donna, too shy to hear his response, gave him a sudden squeeze. That always worked and Sam stopped wriggling and lay obediently on the mat looking up at her from between her thighs.

"You show me the holds, but never how to escape from them," Sam croaked.

"A properly locked figure 4 is impossible to escape from," Donna's voice was becoming increasingly breathy, "Once your opponent slips you in, you're hers until she decides to release."

"At least it doesn't hurt."

"Oh, it could," she replied, fighting to hold back blonde hair, "Your head is joined to my hips. If I thrust, you would be in agony."

Sam instinctively reached for her legs but stopped unsure whether he could touch her.

Donna could see his predicament, "Yes, I really shouldn't have worn these shorts!"

"You have amazing legs," he croaked under their pressure.

"Thank you," Donna muttered shyly, easing the pressure around her student's neck. She really was starting to like this guy. The touch of his skin against her bare legs felt nice, and unlike most people she fought, he wasn't desperately trying to escape her body.

"Even nicer now," Sam smiled.

Donna was embarrassed by the unexpected compliments and, despite his chat up lines being completely inappropriate, she didn't want to let go.

"It's okay, you can try to get out."

Sam wrapped his hands around Donna's thighs and pulled, but the woman's body tightened further, her legs starting to close in on his breathing. Donna moaned quietly as her student's hands now caressed her thighs, sliding higher until his fingers slipped inside her shorts. "Oh yes," she mouthed as she watched the bulge from his erection.

"Keep going... I'm not going to let you out."

Sam's gorgeous hands were gently tickling her and pushing further inside her shorts. She swallowed nervously. Such intimate and uninvited touch from a stranger would normally have resulted in her breaking his arm or even his neck, a single flick of her hips and he would be dead, but Sam was different. His touch was in danger of overwhelming her body and her cheeks were reddening.

"Let me show you an arm bar," she trembled.

Donna lay on her back and nestled her shorts up against the side of Sam's head. She placed one leg over his neck and the other over his chest and pulled down on the arm that ran up between her thighs.

Her student was again completely immobilised, pinned beneath her legs with his shoulder at the very limit of its movement. Sam was breathing heavily, but instead of tapping out, he turned and kissed the back of her thigh. Excitement throbbed through her body and she gripped more tightly around his wrist.

"I'm sorry," he cried out in pain, tapping the mat with his free hand.

Goose bumps were forming on Donna's legs. His kiss felt so intimate and loving that she desperately wanted him to kiss her again.

Sam tapped again.

"You've lost that privilege," Donna panted.

His body fought hopelessly against hers, "Then how do I get out?"

"Kiss me again," Donna stuttered, her face reddened.

Sam's lips touched her again, this time at the hem line of her short shorts and then on the red fabric between her legs, "Fuck..." she mouthed, her body unable to take the stimulation.

Donna swung her legs over and released his arm, "Please don't tell anyone about this," she begged, desperately self-conscious of her behaviour and her tiny shorts.

"I won't... if you have dinner with me tonight."

"Dinner?" Donna exclaimed, edging closer on her knees.

"You can wear those shorts if you like."

"Maybe not," Donna giggled.

Now focusing intently on each other's eyes, Donna edged closer on her knees and caught Sam's arm.

"Fuck," he smiled.

"Fuck?"

Donna slowly turned his wrist to force him on to his front. She spun around above him and sat back on her haunches with her shorts nestled into the back of his neck. Facing down his prone body, her hips and thigh seemed all engulfing as she pulled her feet in around his face.

"How do I get out of this one?" Sam mumbled incoherently; his mouth deformed by Donna's weight.

"With eighty kilograms of way too short shorts on your head? You don't!" Donna giggled, "And the loser has to kiss my feet."

"I could kiss so much more..."

Donna sunk further on to his head and rubbed her bare soles against her student's red face. Her body tingled as the gorgeous man kissed her feet. She shook from the power rush as Sam obeyed her, his lips tickling her feet. His strong hands were blindly exploring her hips and trying to reach further.

"Still want to take me for dinner?" Donna breathed, bouncing her shorts gently on her prey.

*

They met at the bar, then moved to the restaurant and then booked a room at the nearby hotel. Sam opened the door and led Donna inside; her blue sequin dress matching her high blue heels, that made her as tall as her date. She rarely wore something so revealing as it exposed too much of her body, but tonight she wanted to be herself. Her blonde hair hung down over her shoulders with a curl, above her partly exposed breasts.

Sam followed her in, his tan chinos and white shirt showing his own slim, gym toned physique which he knew was no match for Donna's body.

"How could such a beautiful body cause so much pain?" Sam asked.

"Mmm... do you dare spend the night with me?" Donna was becoming gigglier with champagne.

"I can look after myself."

"Really?" she replied with a grin and raised eyebrows.

She was still giggling as she took his wrist, twisted it, and dropped Sam to his knees, "Still sure?"

The giggling assassin then stepped over his shoulder and increased the pressure on his arm.

"So, if you're weren't a nice girl, what would you do now?"

"I am a nice girl!"

"Really?"

Trapped on his knees in an inescapable hold, Sam lifted the hem of Donna's dress and touched his lips against her delicate blue flower-patterned underwear that pulled tautly around her athletic body. Donna cried out in complete surprise, suddenly conscious of her damp underwear. A moment later, though, and her panties were the least of her concerns as Sam pulled them to the side and kissed her vagina.

With her wet underwear now by knees, she continued to hold her date in an inescapable arm lock as she leaned against the wall trembling. Sam's tongue brushed across her, "Slowly," she pleaded but it was too late as the thrill built and she orgasmed.

She felt wonderful as the hormones pulsed through her body and it was only when her mind refocussed that she realised she still had Sam captive in her armlock, "Oh wow," she panted, releasing him to reveal his flushed, orgasm covered face.

"At least I know how to escape from that hold," Sam smiled.

Donna could feel her red cheeks as she modestly pulled her underwear back into place and let Sam lead her to the bed.

Sam unzipped her dress and watched the fabric slide over her curves as lay down. He started with her lips, moved to her breasts and then to her legs. Kissing her damp underwear made her moan out loud and she spread her legs so that his kisses could delve deeper between her legs.

"Careful of my thunder thighs," Donna moaned, "I can't guarantee you'll ever come out..."

"They're beautiful..."

"Really?"

Sam's lips were pressing against her underwear, her clit stimulated like crazy, when her core muscles engaged, flipped her legs over and catching his neck between her thighs. She jerked his face closer, his nose now between her butt cheeks before, closing him up in a tight figure of four.

"I warned you," Donna giggled on an aroused and inebriated high.

Sam's crushed lips tried to kiss the fold between her naked bottom and her thighs, his loving touch rewarded by a slight loosening of her grip.

"Naked bodies are so much harder to escape from," Donna breathed, her arousal building, "I can tuck you in even deeper and, of course, I never want you to leave."

Sam turned his head to kiss her other cheek, but the impulsive blonde mistook it for a bid for freedom and she tensed up, her thighs clasping and locking together to form an inescapable collar.

"Just... kiss..." he gasped.

"Oh, sorry." Donna loosened her thighs.

Sam paused to catch his breath; his head enveloped by her wrestler thighs, his mouth crushed and his nose poking between her bare cheeks. His cock was hard, and he wanted to make love before he climaxed, but there was no way out of Donna's claustrophobia inducing head scissors.

"Make love?" he mumbled.

Donna thighs stayed locked, but he could feel her lips around his cock, "Oh, fuck...". His efforts to escape only hastened his orgasm, leaving him panting and muttering sweet nothings into her bottom.

Donna's lips were still toying with his penis, "Remember you're only ever five seconds from passing out," Donna whispered, "but be good and I'll release you in the morning."

"Morning?"

Sam felt a wave of claustrophobic panic roll over him, as he lay on his side locked in Donna's head scissors. His nose was pushing her underwear between her cheeks and, with his mouth all but blocked, his only air was filtered through the warm blue lacy fabric.

"Breath control is a wonderful way to control your opponent," Donna voice was raspy, the anal sensation tingling her entire body, "You have no air to fight back with..."

Sam's fingers sketched around her body, looking for a way out. All night? How could he sleep? He relaxed and let his face sink deeper into the woman's body. She smelt wonderful and her hold was wonderfully intimate. His cock was erect and bouncing and he could feel Donna's breath.

"May I?" she called.

Sam moaned loudly, pleasure coursing through him as Donna's lips engulfed his cock, which was again helpless to do anything but slide slowly back into her waiting mouth. Her lips sealed up around it, just like her thighs had sealed his head.

Donna smiled, it reminded her of her dildo that she would suck to quench her desire for oral sex. This was better. Warm and real and constantly hard. Sam was wonderful. Women opponents would leave her leg scissors feeling humiliated, even disgusted, yet for Sam, the same punishment created a permanent erection. It made her feel beautiful and wanted, and horny as hell.

Donna rolled on to her back, crushing Sam's head between the bed and butt. She could feel his features compress into her strong glutes and guessed from the silence that she had sealed him completely. Martial arts holds had always given her an amazing feeling of strength and power, a feeling multiplied by Sam's intimate touch. She was still trembling and pulsing her bottom on Sam face as he climaxed and exploded into her mouth.

Donna rolled back on to her side and listened to the grateful hot breath pant between her cheeks. She gave her date one last squeeze before opening her legs.

She giggled, "You thought I was really going to keep you there all night!"

Sam still hadn't moved his head from her inner thigh, "Maybe I wanted you to," he grinned, kissing Donna's thigh that hovered menacing above his head.

"Oh!" she exclaimed, she hadn't thought of that, "Well I still might!"

Sam climbed slowly to his knees and clambered, almost punch drunk, to his feet, "Champagne?" he asked as he fetched the bottle that room service had just delivered.

"Do you want me more drunk?" Donna giggled, pulling the sheet back over her and shaking her blonde hair forward to give her a look of innocence, "I might no longer be a nice girl..."
