At the fun fair

"Look Penny, they have trains!" Sheldon grins in childish glee, watching the scale model trains go round and round the track. They were real working steam engines, just scaled down until each carriage was just big enough for a child to sit on. He watched, fascinated as the engines built up steam and hissed away, pistons driving little steel wheels. "I do love trains"he sighed happily

Penny's standing off to one side with a long suffering smile, clutching a huge teddy bear she won on the rifle range and cotton candy on a stick. she'd dressed cute casual for today, in her loose fit jeans with the little turn ups and a pale shirt with a coloured dot pattern, but she should have guessed she'd not keep Sheldon's attention when there were trains. As it was Leonard was talking about the latest cello practice with Leslie, with enough smugness that Penny was sure it'd ended up in his bed. Howard and Raj were discussing angular momentum and simple harmonic motion of spherical masses, which sounded scientific until she listened enough to realise they were watching women's breasts jiggle on the pirate ship ride.

They'd been round the fun fair all day, and it'd been great fun, apart from Sheldon's horror at the burger stall for lunch. Fortunately she'd helped him pack sandwiches (fresh bread, no crusts, tinned meat, good mustard) so he could eat without risk of contamination.

Leonard ponders "What is it with him and trains anyway? he hates buses and all other public transport"

Howard grimaces "Never ask him that, or he'll tell you of the time he swallowed a model train and spend three days chanting "I think it can pass". Oh the horror!" He shudders

Raj (who's sneaked a hip flask in to top up his soda) laughs "He has a Z gauge butthole! "

Penny winces then laughs "I always wondered why a brilliant man like Sheldon likes playing with trains so much." She looks over at him, wearing his special train hat. "He said as a child things were scary and confusing and trains represented order. He could organise them, sort them, set them up and control them. They help him stay calm. "

All three of them look at her quietly for a moment, nonplussed. Then Howard gets on his phone and googles model trains "Man, a Z gauge loco is over an inch long!"

Penny shakes her head and eats more candy floss "You lot are gross sometimes"

She suddenly goes up on tiptoe and looks round "Where's Sheldon gone?"

he's nowhere to be seen.

"Dammit Sheldon where are you?"

Her phone buzzes. It's a text from Sheldon, with directions to follow.

She left the bear with Leonard and Howard looking at the roller-coaster and headed for the cotton candy vendor. She cut down the side of the stall, between the hot dog vendors.

Was Sheldon getting bolder? She rounded the corner and found him leaning against the wall, casually playing with his phone.

She almost pounced on him, laughing as she pushed him against the wall.

"Dammit, you've been edging me for hours! This little thing is powerful."

"Of course, I needed something strong enough to get your attention and keep you properly stimulated"

"Cut it out or do something about it, I'm in the mood to jump you right here"

She leans in close and whispers into his ear, her breath hot on his skin "Sir."

"Oh yes?" He thumbs his phone. It beeps. Her phone pulses silently once in answer and the smart little vibrator over her clit throbs to life, pulsing for three seconds. She's so sensitive from the teasing she shudders and pushes against him. His grin has an evil glee to it as she grinds her hips on him, breathless with need.

"I'm glad I didn't let you talk me into wearing that electro-stim plug you had, I'm soaking as it is. You just love having a remote control girlfriend don't you?"

She strokes the front of his pants, finding his hard on . He's erect and thick in her hand

"Oh, you do love it, don't you, Sir?"

She looks round, they're out of sight but only a short way from the main crowd, they could be found at any time. The idea makes excited and nervous, makes her want to drop to her knees and suck him off right here and now.

He holds up a staff ID card and a bunch of keys with a knowing grin.

Oh, of course. It seems obvious to her now, he'd have lost that proud erection he's sporting to the worry of sneaking into a staff only area if he wasn't somehow staff, he didn't get off on breaking rules and risk as much as she did. Order and Control was his thing.

"Follow me"

They go deeper into the back lot, winding through the backs of buildings, the trash cans and the unused stalls and props packed away. He stops by a heavy metal door and sorts through the keys. Finding the right one he opens the lock and tugs it part open with a grind of metal on metal .

Inside is dark and musty, the only light is from the part open door. She can just make out narrow paths between piles of boxes and tarp covered shapes.

"In, quickly"

She darts in, and he follows, closing the door behind them then locking and bolting it.

Pressed together in the dark she grips him tightly and he returns the urgency, pushing her back against the cold metal of the locked door, kissing her passionately as he grips her wrists, holding them over her head. She lifts her leg, wrapping it round his, struggling in his grip, wanting more.

he leans his head in, softly biting the side of her neck. She moans, her whole body alight. hours of tantalizing teasing have her wet and eager.

He pulls back, making her growl in frustration. Another tease?

He takes her hand and leads her into the darkness. Their eyes adjust enough to make out shapes in the gloom from the dirty skylights overhead.

"What is this place?"

"Stores for the special events. Folded down stalls and the larger theme props."

he leads her deeper into the maze like warehouse. They wind past a flat packed castle, a giant creepy looking clown head, a huge dime on its edge, a large model dinosaur and all sorts of crates and covered shapes. He pauses in front of a waist high tarpaulin covered object.

"ah, here they are" he throws aside a dust sheet with a dramatic flourish

"the Stocks from the Ren faire weekend."

Penny stands dead still. In front of her is a broad wooden beam with three holes in it, set on a sturdy wooden pedestal that holds it at waist height. It's all bolted together with big black metal locks and hinges that makes it look intimidating in the half light.

"Are you Serious?"

Sheldon rattles through the bunch of keys again and selects a smaller one. He pops it into the big iron padlock and snaps it open. He takes off the lock and lifts the hasp, the whole top half of the stocks hinges up.

"you want to.. want me to.. in that?" she shudders and looks round.

he smiles a smile that looks positively sinister in the gloom. "I thought you were in the mood to jump me right now? well, I'm in the mood to take you right now, like this"

He grabbed her pony tail and pulled her to him, forcing a kiss on her lips as he rubbed the crotch of her jeans, pushing the hard little cylinder of the vibe so it rolled back and forth over her clit. She felt scared and excited, on fire and breathless at once.

"Who's are you?

"Yours Sir"

"You trust me?"

"Yes sir."

"you green?"

She caught her breath a moment. he was making sure she was alright. This was all just a game, more sexual exploration. He was saying she could stop if she wanted. But she didn't want to, she wanted him and however he wanted her, she'd do it

"Green sir"

He was unbuttoning her shirt. "Good, Good. " Still holding her by the pony tail he turned her round, pulled her shirt down and back by the collar. he threw is to the side. She shivered, feeling exposed. He pushed her head to the open jaws of the stocks, resting her neck in the middle larger hole. Long deft fingers folded the clasp of her bra and popped it open. He pulled the strap down one arm, took her wrist and put it in the first hole of the stocks. then her pulled it down the other arm and off, dropping it on her shirt. He took her wrist and put it in the third hole. He closed the top of the stocks down on her with a low squeal of metal hinges, the wooden bar trapping her, topless and forced to bend over sharply at the waist.

He closed the lock hasp and pushed the padlock through. the metal CLICK as it locked made her stomach like ice. She was trapped, near naked in a strange place in some weird medieval device, she could feel the sudden fear grip her. She couldn't turn her head, couldn't see Sheldon, what if he left her here? it was irrational, she knew he'd never do that, but the fear still gnawed at her.

She jumped when a hand touched her back, fingers running up her spine, hands reaching round to stroke her breasts, tug at her nipples. "Sheldon?"

He walked round to the front of the stocks, holding a ball on a buckled strap. "Open wide"

"Why, what are you mmmmffmmf.. " He pushed the rubbed ball into her mouth and buckled it in place, tight.

She tried to cry out instinctively but only a muffled groan escaped.

He tied a leather cord around her base of her pony tail and pulled her head back, tying it to a loop on the top of the stocks.

"Very nice" He gloated. Then he walked round behind her, out of sight.

She had to struggle, had to test her bonds, found she was held tight

She felt his hands on her jeans, undoing the button, pulling down the zipper, tugging at the waist band.

he pulls them slowly back, exposing the sweet curve of her ass, pale in a shaft of light against the dark wood and denim. he pushes them down, til they're past her knees, trapping her legs for him.

he strokes the lace thong, little more than a few strings on a pouch that held a small wireless vibrator.

he pulls that down as well, exposing the glistening folds of her cunt, the lips red and puffy from hours of teasing. He strokes his fingers over her and she moans, twisting in the stocks.

he puts one foot between hers, stepping over her jeans to keep her pinned, then unbuckles his belt.

He'd love to get a whip out while she was bound like this, work her ass with his hands and a strap until she was red and orgasming with every lash but the levels of dust and dirt made that horribly unhygienic.

Instead, a good hard fuck would have to do. He hardly gave warning, just a hand on her waist to steady her and he thrust into her, the teasing had done it's work well, she was wet and eager for him.

She cried out into the gag, hands making helpless fists as she struggled, somehow being able to pull against the bonds and feel so helpless made her need it more, she wanted to cry out and beg him to go faster, to use her hard. By some unspoken telepathy he knew, as he was rock hard and thrusting fast, she could feel the hours of edging and teasing fight the fear and restraint, feel the tension of an earth shattering orgasm build...

then there was a thump in the distance. a man's voice called out "Hey, anyone back there?"

She clenched with fear - someone had found them!

Sheldon froze stock still, but did not pull out. Instead, she was horrified when he grabbed the tarp and threw it over the stocks, plunging her into pitch darkness. She tried to scream, but caught herself. She stayed as still as she could, hyperventilating in the choking dark under the cover.

the voice again, the tarp lit with a flashlight beam flicking over it. "Anyone back there?"

She jumped when she heard Sheldon casually answer "Just me, I was doing an inventory check" and he slowly started thrusting again, drawing back and then pushing into her with long slow strokes

"Ok, carry on" and the light was gone.

She almost collapsed with relief, heart hammering, so close to being caught - then Sheldon grabbed her by the hips and rammed himself into her, roughly fucking her with all his might. The feel of his desperate desire, his throbbing cock in her, the choking fear and harsh restraint all churned in her, overwhelming her. She struggled, the rough cover heavy on her face as she felt herself close, felt it still building, closer, the darkness and the scent of dust and damp wood, the hands on her hips and the cord pulling her hair. She felt overwhelmed with sensations and just let go, crying out helplessly into the gag as she spasmed with pleasure, her thighs giving way in an orgasm that left her breathless.

She hardly felt Sheldon finish, she was thrashing and moaning, her cunt gripping at him as he came.

She felt him draw out of her and she sighed, felt him pull away the cover and unlock the padlock with a metallic click. He untied her hair and lifted the jaw of the stocks and she fell limply into his arms. he unbuckled the gag, rubbing her cheeks where the strap left red marks.

"you mad bastard. that was wonderful. I can't believe you did that! Is he coming back?"

Sheldon is calm for some reason "we should be fine."

She gets unsteadily to her feet, her pants around her ankles. "We need to get out of here!"

She dresses rapidly, stopping every time she thinks she hears a noise.

Sheldon recovers the stocks and they rapidly sneak back to the door, which Sheldon unlocks.

Back in the afternoon sunlight they blink, unsteadily and as soon as they door is locked Penny grabs his hand and laughing they run back though the back lot and dumpsters to the hot dog stand.

As soon as they're safe Penny proceeds to shower Sheldon in blissful kisses "you are a terrible wonderful monster to abuse poor innocent me" she grins "and I'm lucky to be yours."

Sheldon smiles, then pulls back, disgusted "Urgh, dust!"

He produces a clothes brush and they proceed to brush each other down.

"Let's go and get ice cream!"

Sheldon is cleaning a bench off with antiseptic wipes when Penny comes back with two cones "Strawberry for you, Mint choc chip for me"

Sheldon takes his with a smile and a thank you, Penny thoughtfully wrapped a napkin round the cone to reduce contamination.

They lick in silence a moment, just eye contact and knowing smiles. Penny admires the red marks on her wrists from struggling in the stocks. Wonders if there was the same on her neck... Then Penny starts thinking, really thinking and her brow furrows

"Penny, what's wrong?"

"what was that rational thing you said, "I notice I am confused"? well, I do."

Sheldon looks puzzled "How so?"

"Honey, you once had a panic attack over a possible library fine. You've come a long way but still, boning a hard bound naked blonde in a musty warehouse while someone watches? you're not that far."

Sheldon smiles and looks smug

" So something wasn't as it seemed. Hold on... you were hard the whole time. there can't have been someone else!"

Sheldon shrugs. "Sorry, I'm still new to this" he puts his phone on the table and hits play on a file called guard mp3. a man's voice shouts "Anyone back there?" from the phone speaker and Penny jumps.

"you staged that whole thing?"

"a little. I did vacuum the whole area before hand to reduce dust, check for splinters and so on, and oil the hinges on the stocks. The rest was just a wireless speaker and a flashlight."

"wow.. why?"

"because you reacted with significant arousal to the ideas of harder bondage, illicit situations, trespass and danger, So i decided to arouse you in a safe and controlled environment, to test this empirically"

"you staged all that to get me off?"

He looks at her quizzically "was it worth it?"

"Oh my god, it was worth it!" She slides up the bench and kisses him "thank you Sir"
