Karin made the short walk from her flat to the train station and waited on the concourse as arranged. 8 am was early for her to be up, but this was easy money. As a student she needed all the money she could get and easy money was her favourite kind.

She stood at the agreed place, her feet fidgeting in her old tan boots, trying to stay warm. The cold winter air was blowing straight through her well worn blue denim jeans. Her silvery white jacket gave slightly more protection, but she still looked forward to getting back to her small flat to warm up.

James spotted her from a safe distance. Mid twenties, average height, brown hair and glasses, the description of her was accurate. As he walked closer, he observed as much as he could, ready to take the final decision of whether to go through with this.

She had a pale, slightly long face, pleasant enough without being stunning. In a good light, maybe she bordered on attractive. Her figure was hard to tell through her heavy coat. Her legs looked nice in her well fitting jeans, curvy rather than slim, but still with the advantage of youth. Unfortunately she was standing facing him with her back against the wall and so he was unable to take a view on maybe her most important characteristic.

He was now too close, she had spotted him.

"Karin? Nice to meet you," he said.

She was taken slightly by surprise as she'd been looking the other way.

"James!" She smiled. He smiled back.

"Money arrive? All OK?" James knew she spoke little English, however he spoke even less German.

"Yes."

"Can I get you a coffee?

She was a little surprised by the offer, but also pleased with the attractive, easy smile of her friend for the day. While the money was good and the work easy, meeting strangers was always dangerous. Meeting in a public place helped and she also took other precautions. She had taken self defence classes and also carried an illegal stun gun and a knife. Messing with her could be a very bad idea.

She’d often thought about what she would do to anyone that tried to attack her. Most ideas involved her driving into the forest and handcuffing the unconscious fool to a large tree. Karin hadn’t made up her mind as to whether she would ever release him or leave him to die. It would probably depend on her mood on the day.

However, James seemed OK, tall, attractive, with lovely eyes. He had that slightly nervous, unsure look that usually indicated a nice guy just indulging in a secret fetish.

James ordered from a takeaway counter and they stood together drinking lattes, the language barrier making it hard to communicate other than through the occasional smile. Karin also looked both nervous and excited as she held the hot drink in both hands in an attempt to warm up.

She was leaning casually against a rail that ran along the wall of the coffee shop and provided a temporary seat. James glanced down discretely, trying to take in exactly how she was sitting on the metal rail, but the heavy outdoor clothing hid the all important detail. Instead he watched as she frequently flicked her shoulder length brown hair back over her shoulder; a cute habit in James’s opinion.

With their drinks still unfinished, they started to walk the five minutes back to Karin’s small flat. James deliberately let her get a few steps in front before following, this really was his last chance to decide whether he wanted to go through with the day as planned. Once at the building, James followed her as she climbed the steps to the fifth floor. He watched with interest as she walked, focusing on the cute crease that formed around her pert butt and the top of her thigh each time she took a step.

The set up in her flat was basic, but perfectly functional. The smother box was set up in the middle of the spare bedroom. It was constructed of strong hardwood and comprised both the box and a padded bench for its victim to lie on. Both the box and the bench were raised off the floor so that the box lid was at the height of a standard chair.

"Try?" Karin asked as she lifted up the lid.

James removed his overcoat and suit jacket and lay on his back on the bench with his head positioned inside the open box. Karin lowered the lid which closed tightly around his throat and then removed her jacket to reveal a fitted white jumper underneath. Although it was getting too late to change his mind, James craned his eyes to assess her figure and was pleased to see a perfect hourglass, with a narrow waist curving out over full womanly hips and a cute butt.

A few seconds later it was too late as Karin casually dropped down on to the edge of the closed smother box and sat with her jeans less than an inch away from the hole and James’s face. She removed her glasses and rubbed her eye to remove a speck of dust that was causing an irritation. With the irritation removed, her focus returned to James.

"I can padlock if like?"

From his position, the woman sitting on top looked more than capable of keeping the lid shut with her weight alone, but as she was already holding an unlocked padlock, he decided he should play along. "Sure," he replied.

Karin closed the hasp and locked it in place with a cheap looking padlock that grated metal on metal as it closed. Cheap or not, it would hold him. He tried to wriggle his head back out of the box, but with the lid close it was obviously impossible.

“Trap.” she said as she waived a finger as if telling off a kid.

“Yes, I see.”

Karin slid her butt off the edge of the box lid and was now fiddling with four short lengths of chain that were attached to the bench, positioned by each of his wrists and ankles.

"And lock here also?"

"Yes, sure."

James couldn't see much as Karin spent several minutes padlocking chains around his wrists and ankles.

"They're quite tight."

Karin stopped and looked at him with a puzzled look on her face. OK it was his fault for not learning some basic German. Certain German phrases such as 'I can't breathe’ could proved to be useful.

James was also concerned about the size of the smother box. It wasn't that deep and as a result, his face protruded slightly through the hole in the lid. At the same time, the inside of the box was padded which made it fit tightly around his head. As a result, there was no way he could turn his head from side to side if required.

He watched as Karin pulled her study table over so that it straddled both the bench and his body and could be reached while she was sitting on the box. She walked back and forth collecting pens and books to set up for the morning. James spent his time trying to grab glimpses of her butt as she walked, to better understand what the day might be like.

"Panties, yes?" Karin asked, having obviously brushed up on that word.

"Sure."

"Good, best for me too."

James smiled, he'd never really considered it from her point of view. Sitting on an uneven surface in jeans probably would be less comfortable for her too, although at least she wouldn’t be at risk of a broken nose.

Karin unbuttoned and eased out of her worn jeans to reveal pale pink satin underwear. One side had ridden up her butt and she pulled it back out as she arched her back and stretched up. Karin’s butt really was her best feature, full and cute at the same time, no doubt the result of living on the fifth floor of a lift-less building.

Karin stood on the bench with one foot either side of James’s chest wearing a strange ensemble of white jumper and pink panties. Even from there, James could smell the perfume that she'd sprayed over her butt, which was strange as he hadn't smelt perfume on her face when they'd kissed earlier. Maybe that was fair enough for someone in her line of work. He tried to identity her brand of perfume as she lowered herself down on to his face, so that she was looking towards his chained up body.

At first she was very gentle, taking much of her weight through her hands that rested on either side of the box. She moved back and forth until she was happy with her position, but once there she removed her hands and sat on him with her full weight.

"OK we start."

This was not a question, but a statement as she straightened her legs out in front of her, keeping a small gap between her thighs so that he could breath. She looked around her to make sure she had the hole completely sealed and then flicked her hair back and shrugged her shoulders. Karin was now sitting fully on James’s face with only his bottom lip peeping out from under her crotch. All of his other features were gone from view.

Karin's slightly fuller figure was enough to completely seal his face. She even ran her fingers around where her butt met the padded box lid to ensure that all was air tight. James' only air now filtered into his mouth through the small gap between Karin’s almost closed thighs. The air down there was limited and heavily scented, but was just adequate to keep him alive.

Although dark, silent and airless, beneath Karin’s butt was certainly not an unpleasant place to be. Her butt was warm, beautifully so, having just been released from the tight jeans. While her flat may have been cold, Karin's butt ensured that everything sealed up in the box beneath it stayed warm.

"Nose nose nose." Karin said aloud to herself having learnt the word especially. She actually enjoyed the feeling of it pushed deep between her cheeks. The nose’s sensitive sense of smell and delicate airway were rendered completely useless, but at least it gave Karin a fun sensation between her cheeks.

It had only been a couple of weeks earlier when James had been surfing the web while at home on a particularly boring conference call. Google had helpfully translated the page from its original German. 'Long time face sit' the translation hadn't been great but he understood. A German student was offering a full day of face sitting, guaranteed six hours. James liked the simplicity and efficiency of the idea. If she was sitting around studying anyway, and if there was a market for her services, why not sit on something more than just a chair.

Six hours under some strange girl's butt! The idea seemed crazy, at first, but later the idea started to obsess him. Then a few emails and meeting changes later and his next work trip to Germany included a free day.

Even before Karin had sat down, James’s cock had been rock hard. Five minutes later and he was ready to relieve himself, but his chained hands couldn’t get anywhere near.

"......." He tried to talk but his lips wouldn't move, being totally immobilised by her weight.

As talking didn't work, he rattled his chained hands repeatedly in an attempt to get the woman’s attention. Karin put down her pen and leaned to one side so that one half of her butt lifted up from his face.

"Six hours, yes." Again it wasn't a question.

"Yes, but ...." Was all James managed to say before the front of her pink panties rested back down on his mouth.

He rattled again and Karin responded by closing her thighs. Within a few seconds James found it harder to breath. Karin again stopped studying and looked down at her lap to monitor the situation. Only when the rattling of chains stopped did Karin open her thighs slightly. She smiled as she heard the desperate intake of air from beneath her.

"Only good boy have air." She said as she returned to her work.

Karin continued to read her notes and then started to answer questions from previous exam papers. She filled one page with her scribbles and then turned over and continued to write. It was going well, if this question came up in this year's exam then she would be fine. An hour had passed and she hadn't once thought about the guy beneath her.

James lay still in his sealed prison, he now knew what would happened if he made a noise. The big thighs above him would touch, skin against skin. Barely any movement on her part, but it would cut his air supply. As far as he knew that could result in his death.

But then she was giving him what he’d signed up for. All was black and silent. He was in complete sensory deprivation, apart from her scent that he was breathing in. The perfume was fading to reveal more of her own fragrance. He was turned on for sure, but he also felt very relaxed. Beneath Karin was a very calming place. There was nothing he had to do, indeed absolutely nothing he could do.

The hole in the lid of the box was his only window out to the real world and Karin’s butt and thighs filled it completely. As such he was fully focused on those parts of her body. Occasionally she would shift her weight, slightly changing the way she was sitting. Although these movements were slight, they represented big news down in his tiny world.

Karin finished the exam paper and turned on the radio. Although the sound of the radio was barely audio to James, he could feel the small vibrations as she tapped her foot on the bench.

She wriggled her body and felt his features beneath her. She loved the power this work gave her. It wasn't often in life that you could snap padlocks shut and leave someone helplessly in chains. And then stimulate yourself by sitting on their face. And with her personalised panty blindfold pressing directly on his eyes and taking away his sight, there was no risk of him seeing what she was doing.

She lent to the left and lifted her butt off one side of the box. As she'd been sitting for so long, her skin had stuck slightly to the black padding of the lid. Her pink satin underwear had also stuck to his face and it peeled off as she moved. “OK in there?”

James looked up at her with his one free eye trying to read her expression, which was a mix of confidence, arousal and sleepy all at once. He opened his mouth to reply, but was too late as she sat back down, once again putting his mouth into a panty straitjacket.

With true German efficiency, Karin stood up exactly three hours after she had sat down. "Lunch now."

Still chained up in the smother box, James angled his eyes as best he could, but with his face held firmly in place, there was very little he could see other than the old peeling paint on the cracked ceiling.

"Wow, that was amazing!"

Karin smiled as she eased her jeans back up. "You welcome." She then perched on the edge of the still locked smother box and looked down at him.

"Is jeans OK?"

"Yes, very nice."

Karin smiled and edged a little closer so that the edge of her butt was touching the side of his nose, her hair now falling down partially covering her face.

"I can do dress also?"

"Dress? Sure."

Karin stood up, stretched and flicked her dark hair back over her shoulders. Without appearing to be in much of a hurry, she started to unlock the padlocks and opened the box.

By the time James had climbed to his feet, Karin had already disappeared into her bedroom and so James stretched and then hunted around for the toilet. The bathroom was small and badly decorated, but well ordered and clean. He found the bottle of perfume that he had been breathing in all morning. It wasn’t a big name brand, just a cheap copy.

When James returned, Karin was standing in the middle of the small lounge wearing a short black cocktail dress and heels. She had also put on a little make up and her hair was up in a bun. She’d also removed her glasses even though everything was now slightly blurred. The truth was she liked her attractive, polite guest and despite their brief and very unusual encounter, she wanted to make an effort.

"Like?"

"Beautiful."

"And special." Karin pulled up her dress to reveal the briefest of black thongs.

James smiled, even though he preferred her previous choice of underwear, the thong leaving nothing to the imagination. It revealed her whole butt, making it look slightly larger and therefore more intimidating. The g-string was buried almost out of sight between her cheeks.

"In."

"That was a quick lunch break," he replied as he climbed back on to the bench and positioned his head in the box. Karin quickly closed the lid and sat down on one edge. James playfully tried to reopen the box, but Karin just edged a little closer, looked down and shook her head.

"No possible."

As he pretended to try to lift the lid, he accidentally placed his hand on her thigh. Karin didn’t say anything, but stopped moving and closed her eyes. James watched her and left his hand there for a few seconds before slowly sliding it off.

“Staying!” she ordered, embarrassed by the silence that had followed.

Karin stood up and walked away, her little black dress bouncing as she went. James listened as cupboards opened and closed in the kitchen. He could have escaped, the smother box wasn't locked and there was no girl sitting on top, but he remembered the look she'd given him earlier when he’d disobeyed her and decided he should ‘staying’.

When she returned, Karin moved her table to the other side of the smother box. She then relocked the chains around James hands and feet and re-padlocked the box lid. She sat on the edge of the lid the other way round, now facing away from his body. She opened her legs, pulled back her dress and looked down at James’s face that was showing between her bare thighs.

"Face other way."

"Sure, that would be ...." James was getting used to his replies being cut short as Karin lifted her skirt and slid forward so that she was sitting on his mouth and nose, with just one eye peeking out from deep in her crotch.

"......."

"What?" She slid backward just enough to let him talk, although his lips were still touching her thong.

"......."

Again she slid forward just as he was about to speak. She giggled at the look of frustration showing in his one visible eye. Karin slid backwards again but this time James decided to stay quiet.

“Good boy.”

With the lesson learnt, Karin took some of the bread and cheese that she had prepared and pushed it down between her thighs and into his barely exposed mouth.

She had deliberately positioned herself so that she was sitting on his chin and lower lip, and she knew from experience that she would get a very pleasant massage as he ate. The poor hungry guy would try and move his jaw, no matter how difficult that was in his desperate attempt to fill up. And the bread that Karin had chosen certainly needed chewing.

Karin threw her head back and enjoyed the feeling. All she had to do when it stopped, was to open her legs, hand down another piece of bread and then close up. She knew that mealtime spent this way could last at least an hour.

"Bye bye." With lunch over, Karin pulled her cheeks out and slid forward until his nose was resting comfortably against the front of her black silk underwear. With her legs apart, he had been able to see. However that didn’t last long as her legs moved together meaning total darkness beneath.

James lay there trying to keep his nose as far from her panties as possible. Breathing was dependent on there being at least a small gap between his nose the front of her black thong. But as Karin continued to study and her mind wandered, the stimulation from his nose made her sub consciously slide forward.

After ten minutes, and with his nose now buried deeply into the front of Karin's underwear, James started to rattle his chains. At first she was annoyed, as she was halfway through a timed question, but then she realised the problem and slid back off his face.

"You want breathing?"

“Please!” he panted.

She reached over and picked up a soft, flexible plastic tube from the nearby cupboard. It was like a small snorkel pipe. She placed one end in James’s mouth and let the spare end hang over the side of the box.

"Really bye bye now," she smiled as she slid forward, pulled out her cheeks and sat on him so that she engulfed his face entirely. She jiggled up and down for a few seconds until his nose was where she wanted it and then sat completely still as she closed her eyes and looked up to the ceiling. Her butt had now completely sealed the hole in the smother box lid.

Karin lifted her dress and then tucked the other end of the plastic pipe down the front of her panties. She positioned it by her clit so that she was stimulated by the suction created by his breathing. Maybe this was unprofessional, but to her it was just a perk of the job. With James gulping down mouthfuls of air straight from her panties, she carefully spread her black dress out to make the guy beneath her ‘disappear’.

Three hours later and James was asleep. Karin could hear his slow rhythmic breathing beneath her and feel the beautifully steady suction against her clit. The front of her panties were now wet and she was a little concerned that some of the moisture may be getting sucked down the tube and into his mouth.

Karin sprayed her skirt out around her again, to double check he couldn't see what she was doing. She then took the ring that held the keys to the padlocks and played with them in her hand. If she was to lose one of them or even break one, he might have to stay the night. She placed the tip of one of the keys into a small gap beneath her desk and pushed down gently.

She looked behind her at her guest. An attractive guy and he had voluntarily chosen to spend part of his precious life being sat on by her.

He was also trusting her with his life, it made her feel good. She returned to the key that she had squeezed into the desk and pressed a little more. It unlocked one of James wrists. She was very tempted. What would they do if the small key was to snap? She knew that there was no spare.

It was 3pm when Karin closed and piled up her books, this was the time she'd planned to finish both her study and her face sitting. She removed her glasses and rubbed her tired eyes and then held her palms over her eyes to let the heat sink in. She stood up and looked behind her at the sleepy face that had been her seat for the last six hours. She removed the plastic tube from his mouth and ran her fingers around the profile of his lovely chiseled features.

"Is that the time?" James asked sleepily.

"3 o'clock."

James smiled as he tried to lift his arms before remembering that they were still chained down. He rattled them gently and looked up expectantly.

She held up the small key ring. "Chains on."

"Oh yes."

"Did you like?"

"It was fantastic."

"Orgasm for you?" Karin reached down and touched his cock through his suit trousers.

"No thanks."

He couldn’t believe he’d just turned down the chance of a hand job. He’d wanted to come earlier, but now the feeling of being beneath her had turned from just sexual into something else. He wasn’t sure what.

“No?” she was also surprised.

"For you?" he offered in return.

Karin looked shocked and shook her head.

“Why not?”

Karin had often thought about getting off by rubbing herself against the guy in the box, but had been too embarrassed to try. She knew from experience that she could be quite loud and anyway the whole point of her service was to arouse the guy and not her. But here was a sexy guy offering her the service. Maybe he would use his lips on her, maybe even his tongue. She sub-consciously put her hand to her mouth as she thought through the possibilities.

She looked down and saw his expectant eyes staring up from the box. They really were cute. He was willing and anyway she had him helplessly chained up, so maybe she should go ahead.

Apprehensively, she turned and sat back down on the lid, once more facing towards his body. She lifted her skirt and positioned her clit as close as possible to his mouth. In this position, the rest of his face was buried out of sight beneath her. She moved slowly back and forth using his face to stimulate herself, with all the action discretely hidden away under her black cocktail dress.

She cried out as she felt his tongue slide into her tight black silk panties and touch her. Again she put her hand to her mouth, ashamed of her outburst. Ten minutes later and her cries of pleasure were still getting louder, she wasn’t sure how much more of this she could take. Her panties were wet, her thighs had goose bumps and her hands were clutching the side of the box as if desperately hanging on.

Twenty minutes later and gasping for breath, Karin finally stood up.

"Fuck." she breathed.

She stood up, smoothed down her dress and retrieved what looked like a shallow box from the other side of her room. It was actually a cover or second lid for the smother box and could be used to cover up the prisoner. “Thank you,” she breathed as she placed the second lid over James’s face.

The box now had a solid shiny metal lid that completely enclosed James’s head beneath. With her guest now out of sight, Karin stripped off her dress and sat on the lid in just her thong and bra. She pulled her knees up to her chest and wrapped her arms around them and sat there with a big smile on her face.

Half an hour later and Karin had showered and changed into a flowery negligee made of silk with matching panties beneath. Her hair was wet and up in a bun and she wore her glasses over slightly made up eyes. With a little trepidation, she lifted the steel cover to reveal James’s expectant face.

“Key or not key?” she asked as confidently as she could as she knelt on the smother box and rattled her key ring above his face.

“Not key?” he replied, uncertain what that actually meant, but in no hurry to leave Karin’s company.

It turned out that ‘no key’ meant Karin throwing the keys over her shoulder where they disappeared into the small lounge and out of sight. It also meant sitting back on his face, facing away from his body, and smiling at his one eye that was visible between her legs.

Karin then flicked on the television and started to watch. James looked up and watched her smiling face, until at one point she realised he was looking at her. She simply closed her legs condemning him to further sensory deprivation in the tomb beneath her.

It was past 8 pm when Karin finally stood up.

"Thanks you," she smiled as she started to unlock the padlocks that secured his hands and feet. James tried to stand up but the smother box padlock was still locked.

"You want me open also?" she asked.

“Unfortunately, I have to go now.”

Karin looked disappointed as she unlocked the remaining padlock and James climbed to his feet and stretched. They looked at each other and smiled, not quite sure what to say.

"That was amazing, thank you," James finally said as he kissed Karin on both cheeks.

"Your pleasure," she replied. James smiled at her cute misuse of English.

"Proper kissing bye bye?"

James looked confused at first, but then Karin turned around and he understood. He knelt down and ran his hands up her bare legs and up under her short negligee. With her butt revealed, he placed his lips at the fold where her thigh met her butt and continued to worship from there. Neither of them was in any hurry.

James eventually stood up and picked up a small length of spare chain that was lying on an old chest of drawers.

"Can I have a souvenir?"

Karin didn't understand and so James draped the short length of chain around his left wrist. Karin understood and picked up a small padlock and gently threaded it through the two loops at the end of the chain. Her pale, ringless fingers gently squeezed the old padlock until its un-oiled mechanism finally clicked.

"How you escape?"

James shrugged as he pulled his shirt sleeve back down, covering his new bracelet. He hadn’t thought that one through yet.

They kissed again on both cheeks and then James left Karin’s small apartment. He looked back at her standing in the shabby doorway. A woman in a nightdress, average height, average looks, disheveled hair hanging over her glasses. Yet she had given him one of the most exciting days of his life. With this image in his mind, he made the short walk back to the station.

James made his way straight to the station bar and ordered a bottle of local beer. He was in a daze, his phone had already rung twice and he just hadn’t bothered to answer it. All he could think about was the day with Karin. He felt the chain still locked around his wrist and smiled, there was only one key in the world that would open that lock and it belonged to Karin. That felt nice, he had no intention of trying to remove it.

He moved to a table at the back of the bar and pulled out his phone and typed in her website address. The photos didn’t do her justice and they certainly couldn’t portray what it felt like to have her sit on your face.

‘Head scissors’ was another service she offered. There were no photos demonstrating what she would do, but from his knowledge of her thighs, James knew it wouldn’t be an unpleasant experience. He pulled himself back to reality to find that he had finished his beer and was already totally aroused.

It was dark outside and it would be a cold night. He had planned to fly back home on the red-eye, but was there another option? He smiled to the waitress who brought his second beer as he started to text.

‘Karin, wonderful day, thanks. Free tonight?’

‘Come,’ she texted back.

It was all the encouragement James needed. He headed out into the cold night and was soon back outside her small flat.

Karin answered the door. Her hair was down and lay randomly around her head, she’d removed her glasses and was squinting slightly to see him in the dimly lit hallway. She was wearing a black night dress that barely reached past her butt, it was old and slightly ripped over one shoulder.

“Pretty not,” she said as she picked at her lips.

“You look fantastic.”

James followed her inside and watched her dig around in her jeans for her keys.

“Here, I unlock.”

“No, no, I just wanted to try something else....umm head scissors.”

Karin thought for a moment.

“You understand?” he asked.

She nodded, she certainly understood those words. She had been delighted to see James again, in fact she had fantasised about him calling her, but in her fantasises, he was taking her out for dinner and then back to make love. This wasn’t quite the same, but it did still give her the chance to spend the night with him.

“For all night, no escape.”

James hadn’t expected that, but he wasn’t going to complain and dutifully followed her into her bedroom.

He stood in the middle of her small room as Karin removed his suit jacket and unbuttoned and removed his shirt and trousers. With James standing in only his boxer shorts, Karin couldn’t help but run her hands quickly over his arms and chest. He was fitter than most of her recent dates and still he was paying her to be there. She hoped this would live up to his expectations.

Karin pulled back the covers and lay down on her bed. She indicated for James to lie down next to her, but with his head down at the foot of the bed to that they were lying head to toe. They both lay on their sides facing each other so that James was looking straight at Karin’s thighs. Once in position, Karin pulled up her night dress and lifted her top leg.

“Inside for you.”

James paused to examine her legs. For a slim woman, she had beautifully curves and her butt and legs were the best part. Up close they seemed large and strong, but not in a muscled way, there was plenty of feminine shape.

James eased his head between her thighs and let Karin pull him right up into her crotch, so that his face was buried into the lower part of her butt. Karin lowered her thigh back down to trap his head between her legs.

“Comfortably?” she asked.

“Yeah,” he replied.

In the cold room, Karin’s thighs felt wonderfully warm around his neck, somehow managing to be both soft and scarily secure at the same time. Right in the middle of his limited field of view was her cute butt with which he was already very well acquainted. Yet he was still obsessed with its beautiful shape and the way it was barely contained in her tight white satin panties.

“This is your danger,” she announced.

“Danger?”

“If you try get out before tomorrow.”

With that Karin squeezed, her legs and butt working in unison to crush his neck. Within a few seconds James was madly tapping out with his hand on the mattress.

“Fuck Karin!” he was hoping she might let him out to recover, but she held him in place with the previous comfortable pressure.

“You understand?” she checked.

“I understand.”

He lay there completely still and slightly shaken, wondering how something so beautiful could also be so deadly. Where the hell did that strength come from? He looked again, this time more warily, at her soft perfumed legs that surrounded him.

Karin pulled a duvet over them both, positioning it so it only just covered her thighs and butt and in so giving James a gap through which he could get fresh air. She switched off the small table lamp and lay down.

“Karin?”

“No talking,” she whispered as she tensed her thighs as a warning.

James felt far too excited to sleep. Her soft warm legs felt fantastic and he amused himself by gently kissing her butt. She didn’t react by squeezing his throat and so he assumed she must be enjoying his attention. After a while he got a little braver and tried to ease his lips underneath the hem of her panties. He didn’t get far, defeated by the tight elastic.

Suddenly Karin’s legs twitched and then again. James listened and realised that she was asleep. All her movements were now subconscious, no doubt as a result of her dreams. She twitched and tensed again. It was like having a neck massage, one that would probably last all night.

He buried his nose into her panties, pushing in between her butt cheek, and breathed. Almost instantly he was rewarded with another involuntary squeeze from her thighs and a small moan.

Exploring his predicament was providing no end of fun. James tried to lift his head to see if he could open Karin’s thighs. Nothing moved, she evidently slept with her muscles tensed, or at least she was tonight. As he relaxed again, he noticed that her grip around his neck had increased in reaction to his escape attempts.

“OK, sweetheart, I’m not going anywhere,” he said, his lips brushing across her butt as he spoke. Her grip didn’t reduce, she still seemed to be compensating for his earlier attempt to open her legs. James ran his hand along her legs and could feel the muscles working with no way to turn them off. It felt wonderful, warm and safe and completely consuming.

An unknown time later, when James had been running his fingertips over her butt and watching the small hairs stand on end, the situation changed. Without warning, Karin relaxed her top thigh slightly, moved her hips back and tightened her gip again. It was a small movement but it resulted in James’s head being pulled further between her thighs. She did it again, thrusting his head tighter and tighter between her legs.

Karin’s inner thighs now rested against the sides of his head and blocked out all sound from his ears. Of more concern, though, his mouth and nose were now deep between her legs squashed up against the bottom of her butt and now without access to air. He tried to pull back out, but her thighs, now tacky from perspiration held him in place.

James didn’t want to wake her up. Even the demonstration of what she would do if he misbehaved had almost killed him. What would it be like to be squeezed between her thighs when she had just being woken up.

He strained his head left and right and finally found a position where his nose could suck in a small amount of air. It certainly wasn’t fresh air, it was coming from about as deep in her crotch as it was possible to get, but it would keep him alive.

Before a little light had streamed in under the blanket, but now he had nothing. With his eyes pushed up against where her thighs met her butt, it was pitch black, damp, almost airless and the atmosphere was getting more and more strongly filled with her scent. Staying alive was now taking effort and yet Karin was still sleeping peacefully. She still twitched as she dreamt, with the twitches that coursed through the woman’s strong thigh muscles crushing James head as they passed.

In felt warm and safe deep in Karin’s crotch, but James missed not been able to see her cute little ass. He decided to reach up and run his hands over her backside instead, but by doing so he inadvertently caused her to cry out in her sleep and thrust her hips forward. The resultant tightening of her butt cut James’s air supply completely. He took his hands away and waited for her to relax so he could breathe again.

That was fun and so he ran his fingertips over her butt and waist again. Again she cried out in pleasure and again she thrust forward. Again James felt as though his head was set in a sealed block of concrete.

James lay there exploring other ways to tease and stimulate this beautiful sleeping woman. She was certainly a heavy sleeper, nothing he’d tried yet had come close to waking her, but maybe he had changed the course of her dreams. Karin was moaning from time to time and her body twitched and fidgeted more than before. She was also increasingly pushing her hips back and forth as if trying to arouse herself against him.

Being so intimately connected to a horny, sleeping girl felt great and meant that James had been aroused himself for most of the night. Karin being aroused had also created a build up of heat and pressure between her legs. James had to lie still for a while waiting for her to relax again, maybe then he could even get his head out of the deepest confines of her crotch and then maybe even get some sleep.

It hadn’t worked. James had spent the rest of the night in exactly the same position and hadn’t even come close to sleeping. He was hot, inundated with her scent, aroused and completely exhausted when she finally woke.

“Hi, morning,” Karin said with her sleepy voice.

After getting no reply, she looked behind and saw James’s face pushed up hard between her legs. She opened her tacky thighs a little and thrust her hips forward so that his head once more stuck out from between the back of her thighs.

“Morning,” James’s dry mouth barely moved, but at least he was back in fresh air, once more facing her beautiful butt.

“You sleep?” Karin’s face was still hidden behind a bundle of wild hair.

“No, but I’m not complaining.”

Karin felt the front of her panties and was embarrassed by how wet she was. She must have multiple wet dreams, but she was hardly surprised given who she’d had between her legs.

“Open up?” James tapped Karin’s’ thigh as if conceding a wrestling match.

“No.”

“Karin?” James was now feeling claustrophobic after eight hours between her damp thighs and started to try to force his way out.

“You forget?” Karin tensed up and squeezed.

James buried his face back into the crotch of her panties and cried out in frustration, how was he going to get away from this crazy girl.

Within seconds, though, James’s cries had changed from pain to pleasure. Karin had slipped her hand inside his boxers and was running her fingers over him. It was his quickest and most intense time ever and he closed his eyes and enjoyed the natural drugs running through him.

James’s eyes were now closed and he felt incredibly tired as he lay there.

“Do you want me to open?”

“No,” he was almost asleep.

“Last chance or I will time lock you two hours.”

Karin started to count down from ten to one. When she reached one James felt a small squeeze around his neck to signify that the prison was now locked. Karin was explaining in a mix of broken English and German how she would absolutely not open up for at least two hours as James fell asleep.

It was past ten o’clock when Karin finally released him. He lay on the bed watching Karin’s butt bounce as she made her way to the bathroom. When she returned she sat down on the bed right next to James’s head and he reached around her and pushed his face into the outside of her thigh.

“Did you sleep well?” James asked interested to know what his attention had meant for her sleep.

“Really good for all night.”

“I thought you enjoyed yourself.”

Karin crossed her legs to try and hide her wet underwear.

“Maybe I should paid to you,” she said standing up and pulling on a pair of old grey track pants and white t-shirt.

James showered and returned to drink a cup of black coffee that she had made for him. When they were both standing, he was taller and bigger than her, yet he’d spent the whole night convinced that she was some kind of giantess. It was bizarre how the female body could do that to a guy’s mind.

Whereas Karin’s mind still hadn’t worked out why this sexy guy was paying her, he was turning her on as much as she was him. Her eyes flicked across his body and she remembered the chain that she’d locked around his wrist the night before.

“Bracelet?”

“Yes. I can’t really take it off without your key.”

To James’s surprise Karin produced the key from inside her bra.

“Would you want other hand?”

James nodded and held out his other hand and dutifully waited for Karin to padlock another shout length of chain around it. James tugged on the padlock and chain to confirm it was locked far too tightly to ever slide off his wrist.

“Is this key in your bra as well?”

“I can put where you liking.”

“You know where I liking,” James smiled as he pulled on his jacket and walked towards the door. Again, standing there in old casual clothes, Karin looked very ordinary and James couldn’t quite believe how such an unassuming girl had exerted so much power over him. He followed her out to the front door where she gave him a kiss on his lips.

“Anytime you want more please come.”

James was just about to open the door when Karin grabbed one of his wrists and hooked yet another padlock through the chain. She then pulled his other wrist over and looped the same padlock through the chain that encircled his other wrist.

“I can lock for you?” she purred.

“Then my hands would be chained together.... difficult for the plane.”

He looked at the padlock that she held between her fingers.

“How would I get home?”

“Maybe you have to come back, begging the keys.”

James was swallowing hard, this was all getting complicated.

“OK,” he replied hesitantly.

Karin had closed the padlock almost before James had closed his mouth. He pulled and twisted to confirm that his wrists were chained together.

“The keys?” he asked.

“Come tonight.”
