Back Door, Next Door

His tongue now started to travel the full length of her slit, probing and licking each hole in turn and then brushing across her clit before returning to her anus to begin again. Her orgasm, delayed by what had happened, grew again, just as strongly as before if not more so, and it was becoming imminent. Nathan seemed to realise, for he licked her harder, faster, probing more deeply into her two holes. She gave little cries of alarm and excitement as his tongue pushed against her sphincter as if to enter, wanting him to succeed but worried that he might. But then she felt her sphincter giving way just a little and she involuntarily jerked away with fright.

He pushed forward, finding her anus once more and stabbing at her with his rolled tongue, trying to enter. But her orgasm chose just that moment to arrive and she was swept away on waves of pleasure, unable to control the jolting and shuddering of her body, unable to stay still so that he could find his target again. He gave up, contenting himself for the moment with returning to lick her slit from top to bottom, intensifying and prolonging her orgasm by doing so.

By the time it was over she was lying back, trembling from head to foot, her chest heaving and her mouth hanging open in wonder. He pulled back a little and stared up her body, grinning at her as she let her legs drop back and pursed her lips to blow a silent whistle of amazement. She looked at him with an expression of both guilt and happiness.

'I'm sorry, I didn't mean for that to happen...' Her voice trailed away as she tried to explain.

'I know.' He assured her. 'But you liked it anyway, didn't you?'

She nodded mutely, unable to admit it out loud.

'And so did I.'

With those few words he dismissed her qualms, and as he spoke he climbed to his feet and wheeled the dressing mirror around to the side of the bed, climbing on and gazing into it to check its position.

'C'mon. Let's lie together.' He patted the bed between himself and the mirror.

She knew they would be able to see themselves in the mirror, that's why he had moved it, and what would have previously been a cause of embarrassment now seemed positively exciting. He would be looking at her twice, once in reality and once in the reflection he would see beyond her.

She scooted backwards up the bed to lie level with him, still not sure if she could believe his enjoyment of what they had just done. But she noticed that his cock was erect again, so at least it hadn't put him off, and maybe he really had liked doing it.

He held out his arms to her and pulled her close, pressing their naked bodies together and running his hands slowly along the length of her back. She tilted her head up for a kiss, forgetting until their tongues were dancing together exactly where that tongue had recently been. But she couldn't taste anything not nice and so she just shrugged mentally and enjoyed their embrace. If he didn't mind, why should she?

After a few minutes he brushed her hair from her face and then, kissing her lightly, he gently pushed her onto her back, glancing into the mirror as his hand went to her breast, cupping and squeezing her soft flesh before moving on, skittering over her belly and making her skin flutter until he found her pubic mound and his fingertips began to explore her slit. She moaned and wriggled deeper into his embrace, letting him do it, wanting him to touch her. He turned slightly to play more easily in her slit and at the same time to take her nipple between his lips, licking and sucking it and flicking at it with his tongue. She groaned at the sensation and parted her legs wider, encouraging him to do as he wished, hoping that he would fuck her, although she realised it might still be a little while before he was able.

Even though full sex seemed to be a vain hope for the moment, he was more than content to kiss and nibble her breasts and play gently with her clit, and she was more than content to let him. The way he stroked and rubbed her little button was sending wonderful surges of pleasure ripping out in concentric rings like waves on a pond. It seemed as if he was intent on demonstrating to her that a man could do far more for a woman without actually fucking her than she ever expected.

She spread herself wider still, raising her knees to make her pussy more available, urging him to play with her more intensively, needing his fingers to find and explore her wet and slippery vagina. She didn't have the nerve to ask him directly, but a finger or two inside her would keep her going until he was hard enough again to fuck her properly. She looked towards the mirror, seeing her reflection as if a strange girl lay there with her legs wide apart, waiting to be fucked. My god, she thought to herself, surprised at how brazen she was capable of feeling with Nathan.

Perhaps he understood, at least in part, because his abruptly fingertips left her clit and began to explore the rest of her pussy, running along the inside of her labia, touching her so lightly that it seemed all the more exciting because she could hardly feel him. Up and down he went, stroking and caressing her, until, without any warning, his first two fingers found her entrance and plunged deep into her vagina. She clutched him hard and cried out with surprised delight, her own fingers digging into his shoulder, her hips automatically pushing up to meet him and envelop his fingers as he finger fucked her. She pressed his head firmly against her breast with one hand while she clung to his shoulder the other, trying as hard as she could to convey her approval of what he was doing. At first he had the other two fingers bent over to glide up along her pussy every time he pushed into her, but then he moved and, without taking his mouth from her breast, he shuffled just a little further down the bed and uncurled his fingers so that they pointed downwards. She caught her breath, because now they were passing over her perineum, getting dangerously close to where his tongue had been before.

Was he thinking of doing with his finger what he had done with his tongue? She wasn't sure, but he was certainly getting closer and closer and if he was she wouldn't stop him. She was nervous, frightened even, of the prospect him playing with her there, but she'd promised herself to try new things and what he had done before had been far nicer than she would have expected. Now, every time his fingertips slid over her perineum, her grip on his shoulder tightened in anxious anticipation. Would this time be it she wondered each time, but each time it wasn't.

But then, just as she had come to the conclusion that he wasn't thinking of doing anything remotely that kinky and realised that she was strangely disappointed, his fingertip found her anus and, without halting his regular thrusts into her vagina, he began to circle, very gently but deliberately stroking around her entrance. She gripped him harder again, holding herself almost rigidly tense, wondering what he intended to do next, aware that wetness from her pussy had trickled down and made all things possible. She wanted him to go further, she knew she did, but at the same time she was scared of it being unpleasant and so she just conveyed her unease with her vice like grip and silently let him continue.

He was beginning to press against her and she murmured unintelligibly in expectation, keen now that he should do it, wanting to try having his fingers in both holes. She felt his finger wriggle at her entrance, seeking a way in, and she pushed back onto it just a little bit, just enough for his finger, lubricated by her pussy juices, to enter. Not far in, just as far as the first knuckle, but a definite penetration. She gasped as he went in, both of then suddenly freezing, holding still until each was sure the other was happy with what was happening.

'Yes.' She told him, voicing a certainty she hadn't felt only a few moments before.

'Yes?' He queried, lifting his head from her breast and looking at her for confirmation.

'I said "yes to anything" before, remember?'

'So you did.' His finger slid right in, pushed in slow stages in time with his finger thrusts into her vagina. 'All right?'

'It's good.' She told him truthfully, a look of wonderment lighting up her face and her anxious grip relaxing again. She surprised herself by finding that she genuinely wanted his finger in her rectum and liked the feeling of it inside her as deeply as it would go.

With his little finger curled out of the way, Nathan soon set up a steady stroke, thrusting into both holes, filling them with two fingers in one and one in the other so that she could actually feel them pressing together through the thin dividing walls. She had never felt anything quite so erotic, so thrilling and so daring, and so damn arousing. She looked at him, wild-eyed and beaming with excitement, holding onto him as his rhythm increased until his fingers were going into her hard and fast and right up to the hilt. It didn't take long before she felt the effect he was having on her.

'Oh god, I think I'm going to cum again.' She told him, surprised at the possibility of two orgasms so close together.

Nathan didn't answer; he simply increased his pace once more, slamming into her with all the speed he could muster, maintaining the tempo until her back arched and lifted from the bed and her muscles spasmed, a series of guttural groans her only sound as a short but violent climax ripped through her.

As he sensed her orgasm fading and her grip on his shoulder began to relax, Nathan slowed his rhythm, letting his fingers move more slowly and less forcefully until they finally came to a halt and he slipped them from inside her. She gazed up at him now in awe, her face red and sweating and her mouth hanging open as she gasped for breath. He smiled silently down at her until she finally licked her lips, closed her mouth and swallowed and then smiled back at him.

'Was that nice.' He asked, semi-rhetorically.

'Was it ever?' She answered breathlessly.

'Can you go again?'

'I don't think I could stand that again for a while.'

'Want to try something better?'

She looked at him curiously, not understanding what he might mean. She shrugged and shook her head to show her bewilderment.

'Have you ever been fucked there?' His eyes flicked down to indicate where he meant.

She felt herself shiver as understanding hit her. 'No, never.'

'Want to try?'

She glanced down, seeing that his hard on had returned, as big and as shiny as ever.

'Will it hurt?'

By using "will" instead of "would" she had already unwittingly told him what she wanted, and Nathan picked up on it.

'Not if we're careful.'

The size scared her even though she knew in her heart that there could only really be one answer to his suggestion. Still she prevaricated with herself, lying there silently fighting to come up with the honest reply. Eventually she said the word that she knew she had to, even though it frightened her to death.

'Okay.'

'Go on your hands and knees then.' He told her.

He waited until she had done as he had asked before leaning over and opening a drawer in the bedside cabinet. She peered sideways to try and make out what he was after, seeing what looked like a number of adult toys of various kinds. She wasn't familiar with such things and she just hoped he wasn't thinking of using any of them on her. He removed what looked like a relatively harmless tube of medication and slid the drawer closed, turning back to smile at her anxious face.

'Lube.' He explained, showing her the tube more clearly. 'Joan uses it.'

He didn't say what it was used for and Kerry was left with her own ideas. Nevertheless, she thought, it was kind of reassuring that he was considering her comfort. She never thought that he might equally be considering his own.

He moved to kneel behind her and she turned her head to watch his cock nodding and waving in the mirror as he moved into place, looking to have taken on a life of its own. She shivered again, nervous and excited in equal measure.

'Fold your arms so that your bum sticks up.' He instructed.

She felt very, very vulnerable positioned like that, her bottom raised high and exposed, but she wanted it to happen and if this is what she had to do, then she would. She buried her face in the duvet to hide from the indignity of it and waited.

'Arrgh.'

The sudden cold made her jump with surprise before she realised it was just the first touch of lube coated fingers on her anus.

'Sorry.' She gasped. 'I wasn't expecting it, that's all.'

She heard him chuckle softly as his fingertips circled her anus.

The gel felt cool now rather than cold, slippery in a lovely, silky smooth way. He was spreading it gently around her entrance, making it possible for her to be penetrated without discomfort, fingertips dipping into her briefly as he prepared her for what was to come. The sensations were quietly enjoyable and she felt reassured, even if she could feel herself still trembling slightly, although she thought that maybe that was just pure arousal now.

She sensed him move more closely into place, edging nearer her, ready to do it. This was the moment. She hadn't expected this to happen when she had accepted his indifferent invitation to call round, and she wondered for a moment if she should back away. Did she really want kinky sex with an older man, her neighbour, her married neighbour? She knelt ready, knowing that the answer was yes, she did. She was prepared to experiment, to try new things, kinky things, and that meant finding a partner who knew what to do and was willing to do it, and in the context of her having the usual youthful and inexperienced circle of friends, that meant Nathan.

His fingers pulled at her cheeks, separating them, pulling the open, and she felt the cold tip of his lubricated cock touch her bottom just above her entrance.

'Sure?' He asked.

'Yes.' She turned her head to the side where she could see his rigid cock, shiny with lube, lined up to enter her, and then she closed her eyes and rested her cheek on her folded arms, waiting submissively for him to begin.

The end of his cock nudged against her and she stiffened automatically.

'Relax, sweetheart.' He told her softly.

The unexpected use of an endearment helped her to let go, reassuring her and allowing her to do as he asked. Then he pushed gently but firmly against her, not forcing his way in but just persuading her slippery sphincter to admit him. She felt it happen, she felt herself stretch open and the head of his cock slide into her. It was a strange and not altogether comfortable feeling, but it didn't hurt, not in the slightest. He paused to let her get used to it and she opened her eyes and smiled a little smile of triumph into her arms, happy at her adventure and counting it as an achievement.

He waited for what seemed like ages and then, just as she was about to tell him to go on, he pushed further in, his cock sliding deeper into her rectum. The feeling of his cock inside her tight rectal passage was wonderful. She hadn't expected the sensation of being stretched to feel so nice, so exciting. She wondered what she had been worried about, this was fabulous.

'Oh yes, that's good. Do it. Push it right in, all the way. Fuck me there.'

She muttered the words into her arms, startled by what she wanted to say and too shy to say it out loud. But he acted just as if he had heard her, pushing forward until his front was pressed up against her bottom, his cock buried full length inside her. She pressed herself back against him, wanting even more. The toe she had wanted to dip had turned into a need to dive headlong in the deep end.

'Is that okay?' He asked, anxious not to hurt her.

'Oh god, yes.' This time she lifted her head and spoke clearly, voicing her increasing need. 'Don't stop, whatever you do, don't stop.'

He responded by slowly thrusting in and out, not yet fucking her hard but still setting up an insistent rhythm.

'Harder, Nathan, do it harder.'

She was shocking herself. It was as if doing something different had released some kind of slut in her. Now he could thrust deep into her, harder and faster, fucking her without worrying if she was enjoying it, because he knew by her words that she was. She felt him adjust his grip on her hips, letting him pull her hard against him with every thrust. Her body was reacting with the tiny beginnings of an orgasm, the kind that she knew would be slow to arrive but that would leave her wrecked in its wake. God, but she was glad she'd risked calling round when she did. She parted her knees a little, setting herself more firmly so that he could do it harder still.

'Okay?' He asked her again as he plunged into her, misunderstanding her movement, his voice breathless with effort and arousal.

'Yes.' She gasped. 'Stop asking, keep going. I'll tell you if it isn't.'

The feeling of his long hard cock sliding in and out of her rectum was divine, an awareness of a sexy fullness coupled with the sensation of her sphincter being pulled back and forth as his shaft slid through it. She looked sideways into the mirror, seeing her kneeling form, bottom high and head low, and watching his cock sink into her body, wet and shiny, and very, very solid. She'd never experienced anything like it and all she wanted now was for it to last long enough for her to climax and then, and only then, to watch him empty his balls deep into her bowels.

Her only concern was that he might come before she did and, although she wanted desperately to feel him come inside her, she didn't want to be left high and dry if he beat her to it, not while she was being fucked in this gloriously kinky way. He was putting all he had into fucking her now, ramming himself hard forward and dragging her back and forth by the hips in time to his thrusts. She gasped at the force of his fucking, watching them both in the mirror and loving every moment of the sexiest thing she had ever done. Inside her the budding orgasm was growing, a tiny point of heat that was becoming broader and hotter, growing perhaps more slowly than if it had been normal sex, but growing steadily all the time. It was just a case of who would get there first.

Then suddenly, as if it had crept up on her unawares, her orgasm arrived, the intense and hot feeling blossoming out and tearing through her body, flooding her nerves with incredible sensations. She came like the proverbial train, screwing her eyes shut and uttering sharp little gasps each time his cock plunged into her, trying her hardest to hold herself still for him, but with her hooked fingers scrabbling at the duvet and her mouth contorted in passion. It was the strongest, most overwhelming climax she had ever had, wave after wave of pleasure rushing through her as if it would never end.

It did end of course, the surges of pleasure gradually dwindling until she was spent, trembling and sweaty, but with Nathan holding her up by the hips and still into pounding her. Part of her wanted him to stop, to give up and let her subside into a post-orgasmic heap, but the rest wanted to feel him come inside her and bathe her bowels with his cum, and that was the strongest part. She knelt before him, head down, her cheek rubbing on the duvet where she had gathered in into her hands, and just let him have her, trying to recover from her climax and get her breath back while he still fucked her. She knew he wouldn't last long and she so wanted him to come inside her that it was worth it.

'I'm coming.'

She wasn't sure if she felt relief or disappointment. She still wanted to feel him inside that forbidden hole, the naughtiness of it still exciting her, but she was beginning to feel a little sore there now that she had climaxed.
