Lisa sat next to Matt on the sofa in the lounge, her mind distracted. Everything was ready - she had all the items she needed, including the letter, and had hidden what needed to be hidden. Her parents were away for the night, not to return until the next day. All she needed now was to get Matt to leave the house for a while. As the credits of the television programme rolled up the screen, she began kissing his neck tenderly.

"Why don't we have an early night?" Matt suggested, the clock showing ten. Lisa smiled.

"I think we should. But," she said sorrowfully, "there's one problem - we're out of condoms."

"Are you sure? I thought we had a few left."

"Positive," Lisa lied. "But the 24-hour supermarket isn't that far away, so you can go and get some for us."

"Why don't we just do other stuff instead?" Matt asked. "A 69 or something?" he suggested. Their previous attempt at the position had ended in disaster but Matt still thought that it seemed like fun. Lisa frowned - she had not considered that he would offer an alternative. This was not in the plan.

"No, I think we should get some," she said carefully. "I'll make it up to you when you get back, I promise," she said, raising her eyebrows suggestively, but also putting her hand on his crotch in case he did not get the message.

"Ok, I'll go," Matt said reluctantly. Lisa smiled and Matt got up to find his shoes and some money. As soon as the door slammed Lisa hurried upstairs to her room to begin preparations. She drew the curtains, switched on the light and pulled out all her props from under the bed; the scarves that would form ankle circlets, the longer pieces of rope that would attach them to the bed, and the scarf that would tie her wrists together. Accompanying the bondage gear was her sleeping-mask to use as a blindfold and her letter, already sealed in its envelope. Lisa went and put the letter in its place and then returned to the bedroom.

Lisa slowly disrobed, neatly piling her clothes in the corner of the room. It was not too cold in the room but she still felt uncomfortable being naked, even in the privacy of her own room. If Matt were here she knew that he would tell her to stop being so silly, and that she was beautiful when she was naked. And then - as he usually did when he got her naked - he would probably try to give her head. She smiled at the thought.

Lisa lay down on the bed, trying out her intended position. She lay across the bed, her head just dangling over one side, her torso lying perpendicular to the way that she slept, her legs spread out wide. Matt would have access to her mouth, her pussy and her ass. She realised now that this position particularly emphasised her ass - what would Matt do to her? The thought thrilled and chilled her at the same time. She hadn't been this apprehensive about the thought of sex in a long time. She had certainly never spent so long planning and preparing for it.

She sat on the bed and tied the scarves around her ankles, loose enough that they would not be uncomfortable, but not large enough that her feet could wriggle out of them. She tied one end of each of the bits of rope to the frame of the bed, by where her legs would be. She glanced at the clock. It had been over ten minutes already since Matt had left. How long would he take - maybe twenty minutes? Lisa turned out the light and then crawled across the floor, feeling her way in the dark, to the window. She drew back the curtains. Moonlight filled the room, faintly illuminating her endeavours. She crawled back to the bed and slid onto it, not wanting to stand up in front of her window with no clothes on.

Lisa pulled the quilt aside and tied the other end of the ropes to her ankles, securing her legs in their final position, her ankles spread two feet apart. She knelt awkwardly on the bed, looking out of the window for the sight of Matt approaching the house. She desperately hoped that no-one would be able to see her looking out - she was topless, after all. The light was off in the room so she hoped she would be okay. If anyone could see her, she would likely be able to see them first anyway.

She felt a sudden urge to touch her pussy but stopped herself. She wished she could be fully tied-up already - to prevent her touching herself - but she did not dare. What if Matt did not return? What if her parents did? What if someone broke in? It was too dangerous.

After a few excruciating minutes she caught sight of someone on the drive. She waited long enough to be sure that it was Matt, and then ducked out of sight in case he looked up at the darkened room. She lay forwards on the bed, her chin just beyond the edge of the mattress. She quickly pulled the quilt across herself and put on her blindfold. As she put her hands behind her back she realised that the quilt was askew but knew it was too late to worry about that.

She heard the front door shut as she began frantically fiddling with the scarf behind her back. Tying your wrists together behind your back is not easy and despite Lisa practising over the past few days it was still difficult. She finished as she heard the stairs creak. She pulled at her wrists slightly and realised that she could probably still free herself. Perhaps that was not a bad thing, she thought in her nervous state.

Matt was making his way upstairs, condoms in hand, when he suddenly noticed the string drawn across between the banisters that he was about to trip over. Suspended on the unintended trip-line was a letter addressed "Matt" in Lisa's handwriting. Puzzled, he picked up the envelope and opened it.

Darling Matt,

A few months ago we discovered something that we both really enjoy. But shortly afterwards I stopped us doing it, for no good reason. I now recognise this, and only want for us both to be happy, in whatever way we can achieve that together. Therefore you will find a present in our room. Be nice!

Love Lisa.

In truth, Matt did not understand the letter in the slightest. Lisa had gone to such lengths to disguise her surprise that Matt did not comprehend her meaning, at least not until he ascended the stairs and opened the door to her room. Lisa was lying sideways on the bed, facing away from him. Her body was underneath her quilt, and the room was dark except for the pale light from the outside. It was enough Matt could still make out the ties around Lisa's ankles that were connected to the frame of the bed, leaving them stretched wide apart.

Excited, he rushed into the room and walked round to look at her head. The moonlight streaming through the window was enough for him to make out the sleeping-mask blindfold she wore and the way that her arms were pulled behind her back - perhaps tied there? Part of Matt just wanted to free her and hug her and thank her for the surprise, but a more excited part wanted to get started. He drew the curtains and switched on the light beside the bed before throwing back the quilt. Lisa shivered slightly as he did so and Matt stood amazed, looking at her already-naked body with her hands tied behind her back, her pert buttocks stuck up in the air. Lisa waited, her stomach churning with nerves.

He knelt in front of her face, bending his head down to be beside hers. "You are wonderful," he told her as he leaned in to kiss her. She was startled initially but then engaged and they kissed passionately. Matt stood up again and Lisa waited to find out what he would do. Would he use her like this, or would he perhaps move her into a different position? How would he extract his pleasure from her, and would he return the favour?

Matt walked around the bed and knelt between Lisa's legs, taking the opportunity to admire her ass, stuck up in the air. Was that an invitation he wondered to himself, but dismissed the thought from his mind. He placed his hands on her legs and ran them briskly up to the top of her thighs. Lisa shivered slightly as he stroked the insides of her thighs on the way up. Matt leaned forward and planted a kiss on each of her delicious buttocks before kissing his way up her sensitive spine, skipping over her bound hands. When he reached her neck he whispered "I love you," in her ear. She turned to try to kiss him and he stretched to awkwardly meet her mouth with his.

Matt sat back and contemplated what he should do. He felt that he should do something spectacular to match the effort Lisa had put into this, but he was all out of ideas, having had no time to prepare. He decided to do the obvious thing for now - after all, he could always keep her tied up after he'd finished round one. This devious thought made him smile.

Matt slid his hand between her thighs and put his fingers flat on her warm pubic mound. He pressed one finger against her slit and felt her wetness. "It seems you've had a head start," he noted aloud and Lisa felt her face flush. His finger-tips travelled upwards and then he pushed two fingers at her entrance, which yielded to his pressure. Lisa groaned quietly as his two fingers slipped inside her cunt. Matt felt how slick she was inside and realised that she needed no further preparation.

He looked down at where his thumb hung uselessly in the air by her bottom and he curled it down, resting the pad of his thumb against Lisa's tiny rear opening, exposed in the middle of her derriere by the wide position of her legs. Lisa's body tensed as she waited to see what he would do. He repeatedly pressed down lightly against the dip of her rear entrance, teasing her. "You'd like me to do it, wouldn't you?" he teased her. She said nothing, merely waiting to see what he would do, unable to stop him and unwilling to encourage him.

Matt pulled his fingers out of her, and on a whim wiped them on her peachy cheeks. Lisa could not believe that he had done this, and tried to feel annoyance rather than the pang of arousal that she refused to acknowledge. He got up off the bed and she could hear him stripping behind her. She felt him walk around to her head and could smell him as he stood next to her. Momentarily she thought of Ruby, and the mouth-fucking that she had received. Blind to Matt's intentions, Lisa opened her mouth wide for him.

Matt inserted the head of his mostly-erect dick into her mouth. Lisa did nothing, and Matt insistently pushed a little more in. He realised that it was then too much for her to be able to do much and he withdrew again. Lisa grunted and Matt repeated the manoeuvre, going deeper this time. Lisa did not protest and he tried four fluid thrusts into her mouth. On the fourth he went too deep, and Lisa gagged. Her whole body tensed up, instinctively struggling against the perceived danger. Without meaning to, she pulled her arms hard enough that her wrists separated.

"No, we can't have that," Matt said as she watched her. He withdrew and then leaned over her body. He tied her wrists together properly, and Lisa knew that she would not be able to escape again. She felt a mixture of disappointment and relief as Matt moved away from her head. After a little while she felt him kneel on the bed between her legs again. He leaned over her, his breathing audible behind her head. His latex-sheathed cock touched her clitoris and then slid upwards along her slit until it found her entrance. Lisa gasped as he slid into her, his body on top of hers, dominating her, smothering her.

They had never had sex in this position before. Matt's cock felt strange inside Lisa, everything was upside down and not how she was used to. Matt gloried in the feeling of her buttocks pressed into his abdomen, enjoying the sight of her helpless beneath him as well as all the usual delightful feelings his dick experienced while penetrating her.

Matt kissed her neck, unsure of what to say - should he be romantic or was that not dominating enough? He said nothing and all Lisa heard was his grunting as he began pistoning his dick in and out of her. She grunted too, involuntarily, as he went deeper inside than she was used to. As Matt slid backwards and forwards she realised that her clitoris was untouched - exposed but uncared for in their coitus. She had been horny for long enough now and she wanted to come, but Matt was not helping her do so.

Matt fucked her at his own pace, all his usual caring and considerate thoughts of her pleasure pushed out of his mind by his excitement as he quickly built to his climax. With a few final deep thrusts he ejaculated inside her, moaning with pleasure. Lisa felt slightly dejected as Matt pulled out. He quickly tied up the condom and cleaned his hands on a tissue, careful not to touch his dick. Thoughts of sex were fleeing his mind but he knew what he should do. He sat on the bed again and felt between Lisa's legs for her clitoris.

Lisa pressed backwards against his hand as Matt returned to pleasure her. This was what she needed and she let him know it, moaning loudly. He simply rubbed up and down and Lisa was in heaven. She could feel her climax fast approaching and she began unabashedly moaning and groaning.

Matt smiled as he listened to Lisa build to her climax. He knew that she was only seconds away, and suddenly a wicked impulse caused him to move his hand away. Lisa's moan of pleasure turned to one of anguish.

"I hadn't finished," she protested, thinking his actions were in error.

"I know," Matt said, caressing her bottom with his other hand, revelling in the feeling of power. After a short delay he began stimulating Lisa again and she returned to moaning. It became louder, building to a crescendo, until Matt stopped again. "Not yet," he told her gleefully.

She silently cursed Matt and decided to try to keep quiet. If he could not detect that she was close, he would not stop. His fingering began again and almost immediately she was moaning loudly with pleasure. Keep quiet, she thought to herself, you want this to end. And yet, something deep-down caused her to moan loudly like a melodramatic porn star as soon as she was close to coming - some part of her that did not want this to end at all, no matter how agonising it was. Accordingly, Matt stopped when she moaned.

"Let me come," she asked him, a note of desperation edging into her voice.

"I will," Matt said. "Eventually," he admitted, after a pause. He explored the sides of her pussy while he waited, running his fingers up and down the insides of her labia, in a sensitive enough region to cause her to groan but far enough away from her clitoris to not be in any danger of an accidental orgasm. "I bet you would," Matt said as he idly stroked her thighs with his other hand.

Lisa reached her bound hands down to her bottom. With her left hand she pushed far apart the two halves of her petite derriere while she felt for the centre with the index finger of her right hand. She felt Matt lift her hands up slightly from her body. He held the palm of her right hand while he picked up two of her delicate fingers. He took them in his mouth and licked them as if they were the tenderest parts of her body, lovingly coating them in saliva. Lisa's mind was focused on her pussy, wishing that his tongue were there instead.

Matt released her hands and she felt again for the bud between cheeks, pressing her wet finger against her own ass-hole, slowly sliding it in and violating herself in a way she would never have conceived of doing earlier in the evening. It felt good, somehow adding to what she had believed to be a maximal level of arousal. It did not feel too much for her to take, she realised. She tentatively pressed a second wetted finger against her hole. Ruby said two fingers were fine, she unexpectedly remembered. It slid in alongside the first, noticeably stretching her tight canal and she moaned.

Matt's cock was stiffening again already at the unbelievable sight of his girlfriend fingering her own ass. He began lightly rubbing her clitoris, not daring to do too much in case it went too far and made her come. Lisa was right on the edge now and felt as if she could come at any moment, like a sneeze that was tickling the end of her nose. But her climax would not quite arrive.

Desperate, she began sliding her two fingers in and out of her ass, trying to generate enough sensation to send her over the edge. She felt it slowly working and she continued finger-fucking her ass, shamelessly abasing herself while Matt watched eagerly, his cock now rock-hard.

"Oh god! Yes! Yes!" Lisa screamed in triumph as she came, her pelvis bucking against Matt's fingers and her fingers as they worked together to deliver her orgasm, waves of pleasure finally crashing delightfully against the shore of her climax. As the amazing pounding in her head subsided, Lisa was dimly aware that Matt was freeing her. He gently rolled her over and removed her blindfold. She blinked rapidly against the weak light from beside the bed. The first thing that came into focus was Matt's erection, standing proudly in front of his body as he knelt over her.

Lisa reached for the condoms that she had hidden inside the drawer of the bedside table and wordlessly handed one to Matt. He rolled it down over his dick without fuss and she reached out her arms to him. She drew him inside her with a tight embrace, her arousal now withered but her love heightened. They clung to each other as they made love, their mouths separating only to whisper proclamations of their feelings to each other.
