Why had he been so generous? Maria was a friend of his ex-girlfriend and in town for a week on holiday. When he met her at the train station he started to think his generosity may be rewarded. She was in her mid-twenties, tall, had a fantastic figure with long brown hair. She was wearing short tight cotton shorts and tight t-shirt. This could be worse, he thought.

"You can take my room" Brad said. "I'll sleep in the spare room across the hall".

She brushed her long brown hair back as she asked in her slight Spanish accent "Do you have a key for this door?"

That was a fair question he thought as she had never met him before and they were alone in the house and his housemate wouldn't be home until late.

"Sorry I don't, I think the spare room is the only room that locks" he apologised.

"That will be fine" she smiled as she took her suitcase into his room.

"But I don't have a key for that room" he repeated.

"Yes I know," she smiled.

Brad had lost the flow of the conversation but before he could think it through his phone rang and he took the call. When he returned, he found Maria by the spare room, "Are you going inside?" she asked as she put the key that had been on the inside of the door into the keyhole on the outside.

"Sure" he said still a little confused as he walked into the spare room.

"Goodnight" Maria smiled as she swung the heavy door shut and turned the key in the lock. Brad listened to the click of the lock echo around the small room that now seemed ominously small and secure.

"Leave the key in the lock" Brad said from the other side of the heavy door.

But Maria pulled the key from the hole and looked back at her host through the keyhole "I'll keep the key" she smiled "just to be very safe."

With that, she reached behind her and tucked the key into the back pocket of her shorts and walked into Brad's bedroom and closed the door.

"Shit!" he said, having now caught up with the situation. He tried the locked door and then looked out of the small barred window. "Shit!" he repeated as he lay down on the small metal bed.

He breathed a sigh of relief as he heard his housemate open the front door. "Louise" he called as she walked up the stairs to his room.

Louise tried the door, "Why have you locked yourself in there?" she asked.

"Just being overly chivalrous," he replied.

At least this was his chance to get out. "As you're here, can convince my jailer to release me," he said.

After a short discussion, Louise reappeared from Maria's room with the key. "What's your freedom worth?" she smiled as she looked at him through the keyhole.

He waited patiently until she'd had her fun before she put the key into the keyhole and turned. "Thank you" he smiled.

A few minutes later Maria came out of her room. "Louise, if you're going out this evening I would like to lock up Brad is that's OK?" she said.

Brad looked at Louise hoping that she'd back him up. "But I need to talk to him before I go" Louise replied.

Maria thought for a minute, "Have you got a chain and padlocks?" she asked Louise.

Louise was taken aback, "I have my bike lock" she replied. Brad didn't like the way this was going.

"Can you lock him to the bed please" the Spanish woman asked.

Like Brad, Louise didn't quite know how to answer this request but went to fetch the heavy chain and two padlocks that were wrapped around the saddle of her bike. "You'd better lie down" Louise said to Brad as she knelt down next to him. She then proceeded to padlock one end of the chain around the frame of the bed and the other around Brad's neck.

"He's all yours" Louise joked as she handed Maria the keys, expecting their guest to join in on the joke.

But Maria just pocketed the keys, "Thank you" she smiled before returning to her room.

Brad and Louise were still in shock. "Please tell me you have other keys for these padlocks," he said finally.

Louise shook her head and laughed nervously, "no, she's got the only ones."

That night, Louise went out clubbing and Brad lay chained to the bed. Louise had even had the cheek to lock the door to his room to 'make sure Spanish girl felt very safe'.

It was 8 in the morning before Louise returned. She went upstairs and unlocked Brad's door. "Exercise time" she smiled as she sat down on the bed next to him. "Still chained up I see" Louise giggled.

"Yes" Brad replied as he tried in vain to sit up, "could you please ask our guest if she feels safe enough to unlock me yet?" he asked.

"She's left" Louise shouted as she opened Maria's room to find it empty.

Brad started pulling at the chain. Louise looked down at him, "You're not going to get free like that" she said.

Brad continued to think of ways to escape and then saw that the metal frame of the bed was fixed together with screws. Louise could see what he was thinking. "That might free you from the bed, but you still can't undo the chain from around your neck" she observed.

"That'll do me for now" he smiled waiting for her to go and get the screwdriver.

She thought for a moment, "Umm, maybe not so quick. I had to wait a age for you to use the bathroom yesterday, I think I'll go first today."

"Fine" he replied, "I think there're some tools downstairs."

She smiled down at him, "No, I think you can stay locked up until I've finished my shower."

"Oh come on Lou," he begged

She walked over to the door, "And I think I'll lock the door as well" she smiled as she closed it behind her and turned the key in the lock, smiling to herself as she walked into the empty bathroom.

It was almost an hour later when she unlocked the door and stood in the doorway in just a t-shirt and knickers with wet hair hanging down her back. "Is this what you want?" she asked holding up a screwdriver.

"No rush" he said sarcastically as he tried to lift his head the couple of inches that he could from the bed.

But instead of handing it to him, she stood on the bed, one foot either side of his chest. "What's it worth?" she asked as she put it within his reach and then quickly lifted it up before he could take it.

"Too slow" she giggled as she moved further up the bed so that she was standing with her feet either side of his head.

After more teasing from her and pleading from him, he decided to take a more direct approach. He pulled her legs to one side causing her to fall down on top of him. After a brief struggle Louise was sitting on his chest still holding the screwdriver. While they were good friends, they had never been anything more and they looked at each other not knowing what to say.

Brad was the first to speak, "Can you unscrew me now?" he smiled.

Louise reached over and started to undo the screws. As she worked she inadvertently slid further up the bed so that by the time she had finished she was virtually sitting on Brad's face.

"Oh sorry" she said as she very slowly moved back and then climbed off him.

"No problem" he smiled back. He then slid the chain along the bed and off the frame.

Later that evening, Brad was sitting in the kitchen with Louise. He hadn't seen or heard from Maria all day and still had Louise's bike chain securely locked around his neck.

"I lent her my pass for the gym" Louise remembered, "maybe she's gone there?"

By the time he arrived it was late and the gym was almost empty. He looked around and saw Maria stretching in front of the large mirrors. She was wearing the shortest pair of gym shorts and t-shirt that really showed off her fit tanned figure.

He walked over to her, "I've been looking for you all day," he said.

"Why?" she smiled back.

He gestured to the chain still locked around his neck.

"I'm sorry about that" she smiled, "but your door was locked when I left the house this morning."

"That's fine" he replied suddenly disarmed.

She walked over to the exercise bike. "Well can I have the key?" he asked.

"I only have the key for the lock on the other end with me" she explained, "the other key for your neck is in my locker".

"Will you be long?" he asked.

"No, just wait a little bit" she smiled as she started to peddle.

She then stopped, "Hey, just to make sure you wait" she smiled as she took a key from her pocket and unlocked the padlock that had been secured around the bed. She then pulled the end of the chain through the support of her bike saddle and locked the chain back on to itself so that Brad's head was chained only inches from the saddle.

"You can watch me cycle" she joked as she sat back down on the saddle and started to pedal.

He knelt on the ground by the bike watching her fit butt and thighs pump the pedals. She started to perspire as she worked harder and harder. Brad was thankful that the gym was empty and that the bike was in the back corner, but still feared that he would be seen.

"Maybe you'd get a better view from the front?" Maria suggested pushing his head around from behind the saddle to the front. Brad was now sitting astride the exercise bike with his head right between Maria's thighs. As the chain was still locked to the back, there was now even less distance between his head and her saddle, such that his face was now resting against the crotch of her shorts.

"Front row seats for the cycling event" she giggled as she slowly brought her sweaty thighs together like a vice closing around her head. She then started to cycle, her thighs brushing against Brad's face on every pedal. She continued to pedal as hard as she could for the next twenty minutes and by the time she had finished his face was soaked with her perspiration.

She then immediately grabbed her towels and wrapped it over and around her thighs enclosing Brad's head. Inside, the heat from her thighs created steam that filed the enclosed space beneath the towel. He tried to pull his head out from her homemade 'sauna' but she clamped her thighs closed again holding him rigidly in place. He struggled for a few more seconds until the increasingly force of her thighs forced him into submission.

"That's better" she smiled as she sat with him still between her legs, "just think how beautiful you'll look after your very personal steam treatment."

"Times up" she finally announced. She swung her leg over, wiping a sweaty inner thigh across Brad's face as she did. She pulled out her key and unlocked the chain from the bike and led him by the chain towards the women's changing rooms.

She unlocked her locker and took out her clothes. "I promise I'll unlock the chain after my shower" she purred as she pulled off her t-shirt to reveal her bra.

Brad sat down on the seat and waited.

"No, you can't see me shower, at least not yet" she smiled, as she beckoned for him to climb into her locker.

"No way" he replied.

"Fine, no key for the chain around your neck" she replied.

He had no idea where she had put the key and hadn't a hope of getting the chain cut off at this time on a Friday night and so had to relent. He squeezed into the locker and watched as she walked over to him, now only wearing her bra and panties. "Have fun" she giggled as she closed the door and turned the key.

He could just she her through the narrow ventilation grill in the metal door until she walked off to the showers and out of view. He could see the locker key resting on the bench on top of her sweaty gym kit.

"Hey someone might take the key" he called out.

"I think its safe lying in my smelly panties" she called back.

She returned with a towel wrapped around her. "I can still see you" he replied in a misguided show of protest.

"Close your eyes or else" she replied.

But he couldn't take his eye off her fantastic body. She couldn't tell whether he was looking at her or not inside the dark locker and so walked over and sprayed her perfume into the vent.

"Arrrh" he cried as it hit his eyes.

"I thought I said no looking" she purred as she finished dressing.

She stood up against the locker door with her butt almost touching the grill. He couldn't believe how sexy it looked up close. "You can look, but you can't touch" she teased, "at least not until I let you out of that small metal box."

He was still breathless.

"Which I don't feel like doing right now" she continued, "as you peeped at me before."

Maria smiled as she listened to him plead. She then took the locker key and slipped it into a pocket of the jeans hanging from a hook nearby.

"OK" she purred, "the key now belongs to the women who owns those jeans who I think is still swimming in the pool. When she comes to change all you have to do is ask her to unlock you. Easy."

Brad looked at the pair of designer jeans that now housed the key, "What if she doesn't unlock me?" she asked.

"It'll be an uncomfortable night for you" Maria whispered through the grill. "But if she does, I'll be at home waiting...."

Brad watched Maria leave and started to plan his unusual but vital chat up line.
