The Adventures of Karen - Part 18 - Learning to Serve ( ff bd ds feet shoes ir Fdom Mdom ) Karen fastened her lips firmly around the long erect nipple, sucking it as hard as she could, while, at the same time, she flicked the sensitive end with her tongue. Greta threw her head back, eyes closed in ecstasy. 'Don't stop, sweet slave, keep on working it as hard as you can.' Karen did not need any encouragement. Her own eyes were closed tight as she sucked, enjoying the sensation and wishing she dare begin to play with her own swollen teats. Suddenly Greta stood up pulling her nipple from Karen's grasping mouth with a distinct 'plop!'. Karen looked up at her mistress, disappointed that the pleasure had stopped so soon. 'Did I fail you , my Mistress? Did I fail to please you?' 'Oh no, sweet slave. Far from it!' Greta stood upright and shook herself so that her full, round, heavy, tits jiggled excitingly in front of Karen. 'Let us get you more comfortable. Stand up and remove that little costume.' Karen stood up next to Greta, and began to unfasten the straps that ran around her waist. As she did so Greta helped by loosening the two fine leather thongs which ran down between Karen's legs, the thongs which had held and separated her swollen labia for so long. Slowly, between them, the various straps and buckles were undone and the heavy metal rings which had encircled Karen's dark nipples were pulled off, leaving the nipples and areolae standing proud and engorged. Karen began to bend to remove her shoes, but Greta stopped her. 'Wait, my dear, allow me.', she pushed Karen back on to the bed and lifted her left leg. 'Let me take these off for you.' As she unfastened the tiny buckles that held the thin strap around Karen's ankle she smiled. 'You like wearing these, my dear, do you?' 'Yes Mistress, I do. The feeling of the tight straps helps to remind me that I am your slave here.' 'Well done, I like that!' Greta picked up the shoe, the insole still warm from its long and intimate contact with Karen's bare foot. 'You know, I like this', she slowly sniffed the warm leather, 'I like the smell of warm leather and female flesh. Do you like that too my sweet little slut?' 'Yes Mistress. May I lick the shoe to show you how much I like it.' Greta smiled, this was going so well. Karl had humiliated Andy by turning him into a foot worshipping and worthless slave and now Karen was revealing her own true colors. 'Go ahead my dear, I shall watch you and I shall enjoy the sight.' Karen happily held the shoe to her mouth. She could smell the warm leather and the faint smell of her own feet, lightly scented from her shower, which now seemed so long ago. She began to lick it slowly, savoring the sensation. She was tempted to turn her attention to the spike heel but thought that that little secret pleasure was one she would hide for as long as she could. 'Enough!' Greta lay, on her side, on the bed beside Karen. As she did so her heavy, dark nippled breasts fell, tumbled, across each other resting warmly against Karen's arm. 'Now', Greta lifted one breast upwards, 'you may feel this and suck the nipple for me. Take your time and make sure that you please me.' 'Yes, Mistress.' Karen moved and moved so that she could get her hands on the soft warm flesh, lifting it so that she could focus her attention on the erect nipple. 'Mmmmm, that is so good!' Greta moved and sat up. 'Let me kneel over you so that you can admire, worship, my tits properly.' Karen lay still as the naked Greta knelt astride her. As she bent forward the heavy, full breasts, the heavy, rounded tits, swung in front of Karen's moist lips. She did not know which hardened tip to savor first as Greta swung her warm soft flesh, brushing Karen's lips with first the left, then the right, nipple. Karen enjoyed the velvety touch for a few moments and then caught one nipple between her lips. She started to suck as hard as she could, she knew that this had pleased her Mistress earlier and it seemed a sensible idea. 'Mmmmmmm, yes, I like that, now do it harder for me.' Greta was clearly enjoying the stimulation. 'Much harder!' Karen continued to suck as hard as she could on the nipple, the left nipple. As she sucked she gently nipped the velvety, rubbery, flesh with her teeth, taking care that she did not hurt her Mistress. She had a good idea of the feeling, after all she had often, so many times, sucked and bitten her own nipples in the solitude of her bed. Those days seemed so long ago now, and she briefly wondered if she would have the chance to pleasure herself on her own ever again. 'Stop! Let me see what you have done to me.' Greta spoke sharply and pulled away from Karen's questing lips. As she sat up Karen looked up at the heavy tits hanging over her. She could see the results of her frantic suckling, the left nipple was red, dark red, and swollen, noticeably more swollen than the right nipple. More than that, the effect of the prolonged sucking had made it much, much ,longer. Karen was fearful as she saw what she had done, perhaps the Mistress would punish her. 'Oh yes, oh yes indeed!'. Greta looked down over her swollen tits at Karen, 'I like that my sweet slave, I like to see how my tits can be treated and pleasured. I think you can continue to work on that nipple.' As she spoke she lowered herself back over Karen's waiting mouth. Karen fastened on to the swollen elongated teat and continued to suck and nibble as hard as she dare. Greta started to moan quietly and to push her heavy tit into Karen's face, almost smothering her as she did. As she moved, and writhed in an apparent, obvious, show of pleasure, Karen was aware that Greta was moving one hand behind her until she could reach the warm moist flesh between Karen's wide spread legs. 'Mmmmm, mmmmmmm!' Karen couldn't help herself as she felt fingers probing between her swollen lips and caressing the sensitive end of her throbbing clitoris. 'Like that my dear?' Greta pulled her nipple out of Karen's mouth. 'Yes Mistress, please make me cum.' Karen could not resist begging for release. The pleasures of sucking that warm swollen nipple had only served to excite her even more. 'Ohhhhhhh!'. Greta pushed a couple of fingers deep into Karen's wetness. 'Oh Mistress, please....' Suddenly, the fingers were withdrawn and brushed across her clit before being plunged deep inside her again, for a few brief ecstatic moments. Greta pulled her hand away and brought it to her, as yet, untouched right nipple. Karen watched in fascination as she saw those wet fingers, coated with her own juices, wiped across and around the nipple. Greta stopped and plunged her fingers back into Karen's eager cunt. Again the same short torment before they returned to wipe even more of the sweet juices across the nipple. 'Oh dear, look at that mess!', Greta smiled down at Karen, 'Lick it clean slave.', she leant down and offered the erect nipple, slick with cunt juices, to Karen. Karen was familiar, so very familiar, with her own taste and happily began to lick and suck the slick nipple. 'Enough, slave, enough!' Greta pulled away and sat up, her full weight across Karen's midriff. Karen became aware of a warmth, a wetness, as Greta's own juices seeped out. Once again she felt the fingers probe her wet folds, her swollen clit, as Greta tormented her almost to orgasm. 'Now, my dear, I can see you like your own juice, so lick my fingers clean.' Greta thrust her fingers into Karen's mouth, watching as, with her eyes closed, she licked and sucked the salty fluids off each finger. Greta looked down approvingly as Karen sucked each slick finger separately, as if sucking a cock, until her hand was finally clean. Greta stood up and looked down at Karen. 'I want you to lie there with your arms and legs spread wide. Just imagine that you are strapped down and cannot move. Can you do that?' 'Yes Mistress.' Karen was relieved, she was dreading the thought of being bound helpless and exposed. Surely this won't be too bad. 'Now', Greta had read the unspoken thoughts, 'you think that this will be easy, but in fact it will be very hard for you. I expect you to remain spread wide and unmoving, whatever I should do to you, whatever should happen top you. If you move in any way then you will be severely, and I do mean severely, caned. I don't think you would like that my dear slut.' 'No Mistress, I don't think I could take the cane. I will lie just as you say my Mistress.' Greta smiled, 'Well done slut, we will see if you can pass your test.' She was pleased, because she had always felt that the sight of a naked, helpless, wide-spread female, free to move, but not daring to move, an incredibly erotic experience. After all it was one of the games that she sometimes played with Karl, pretending to be bound, pretending to be helpless and enduring his torments, knowing all the time that she was free to move, but not daring, not wishing, to spoil the pleasure of the moment. 'Yes, let us see if you are truly submissive. Some of my guests would like to see a girl offering herself like that.' Karen shivered involuntarily, wondering what could yet be in store for her. 'Go on, then, stretch your arms and legs to the very corners of the bed, I want to start working on you.' Karen eased herself in to the center of the bed and stretched her arms and legs wide. 'To the corners of the bed, slut, go on, you can do it if you try harder.' Karen managed a further stretch and found that as her legs, her bare toes, pointed towards the corners of the bed her exposure increased, her legs were as wide as she could make them. 'That's better', Greta smiled at Karen as she moved towards the foot of the bed. She paused and admired the view of the swollen labia, glistening slightly with the juices that were seeping from within Karen. 'Wait, I want you to see this.' Greta walked back and placed a thick pillow beneath Karen's head. The effect of this raised her head so that she could see down the length of her naked body; it also had the effect of increasing the tension in her shoulders as she struggled to keep herself spread-eagled. Greta moved back to the end of the bed and knelt between Karen's naked legs. 'Now, what have we here?' Greta explored the soft moist folds with her fingers, slowly opening them and exposing the inner lips the soft pink inner flesh. Karen moaned in pleasure. 'Yes, this is good.' Greta began to tease the exposed clit with her fingers, teasing and gently scratching the exposed and sensitive flesh. Despite herself, despite her arousal, despite her instructions, Karen could not resist moving her hips slightly, thrusting towards the fingers, seeking relief. 'No, keep still, slut. You know what I have ordered.' Karen struggled to remain still. As she did so, and endured the teasing probing fingers, she began experiencing the pleasure of the enforced, but restraint-free bondage. She thought to herself that it was in fact rather more pleasurable than she would have ever imagined. 'Now, my dear, are you ready yet?' Greta explored the increasingly wet flesh. 'Oh, yes indeed, I like a girl who gets herself nice and wet.' Karen looked down n fascination. What was Greta going to do to her now? Greta used both hands and parted the labia to open up the fleshy petals covering the pleasure area. With a final flick at the reddened clitoris she moved away slightly and held her right hand up towards Karen. 'Meet your new friend, your new lover, my sweet slut!' Karen gasped, wondering and watching fascinated as Greta's hand moved nearer to her wetness. Greta slowly folded her fingers together and placed her thumb down her palm, making her hand narrower and spearlike. 'Are you ready for this, I wonder?' As she spoke she placed her fingertips at the opening of Karen's exposed cunt, the wet swollen opening that was so desperate for stimulation. 'Have you ever been fisted my dear?' Greta looked up toward Karen and stared into her eyes. 'No Mistress, wh-what do you mean?' 'I mean, my dear little slut, have you ever had a hand, a fist, deep inside you.' 'No Mistress, only my fingers.' 'How many fingers my slutty little slave? 'All four, Mistress, but I could not take any more.' 'You will, my dear, you will.' Greta looked down at the wet and glistening flesh. She began to insert the point of her hand into Karen, slowly turning her hand backwards and forwards as she went deeper into Karen. Karen gasped but said nothing as the relentless invasion continued. As Greta's knuckles reached the entrance, as the warm wet flesh was distended, she looked up at Karen. 'You like this my dear?' 'Y-y-yes Mistress, but it hurts me so much.' 'Too bad, because you will take it all and you will beg for it never to stop!' Greta kept on pushing, her knuckles distending the soft flesh until slowly and relentlessly her hand, her whole hand, entered Karen. Karen gasped and bit her lip as the first stretching occurred, but suddenly, she relaxed a little. It didn't seem to be as painful as she had expected. The feeling of an object, a large object, inside her was quite pleasurable. Very pleasurable! She felt the fingers deep inside her begin to flex and stroke her inner walls, her velvety flesh around her g-spot. The sensation was not just pleasurable, it was exciting!! 'You like it now, bitch?' Greta knew that she had managed to seduce Karen. She had lain voluntarily spread-eagled, she had not struggled, she had watched every gentle thrust of her hand and she enjoyed it. Her juices flowed more copiously. 'Yes Mistress, it feels good.' Karen gasped as she felt a finger, or was it a thumb, or fingers, brush the spongy flesh of her g-spot. 'Mistress, you will make me cum soon.' 'Not yet, little slut. You are going to beg me to pleasure you.' 'Mistress, please make me cum.' 'Not good enough, I want more than that!' Karen wondered, what was expected. 'Mistress, please make me cum. Please fuck me with your hand.' 'Better, but not good enough.' Greta kept up her gentle movements deep inside Karen. 'Please Mistress fist me, fist my cunt, fuck my cunt with your fist, pleaseeeee! Begging you, please fuck me with your hand, please Mistress. I'm begging you my Mistress!' 'That's better my slut, as you ask so you shall receive!' As she spoke Greta began pumping her fist in and out of Karen's wetness. As she withdrew her hand halfway she was fascinated to see how the soft wet flesh stretched around hr knuckles before she plunged back inside again, deep and up to her wrist. Karen began to breathe heavily as the pumping, the fucking, continued. 'Ohhhhhhhhhh Mistresssssssss, I'm cummmmmmmmmmmmmmmmmmmmmmmming, cumming!' Greta smiled happily, she had won, she had got Karen exactly where she wanted her. She slowly reduced her pumping and withdrew her hand. 'Oh Mistress, you are so good to me!' 'I know, my dear, I know. Now you may beg to clean my hand.' 'Please my Mistress, may I beg to lick your hand clean of my juices?' Greta ignored her, and held her wet, shiny, slick hand just in front of Karen's face. 'Begging you my Mistress, I'm begging you, please!' 'Very well, and make sure every drop is removed.' Karen eagerly lapped at the fingers, so wet and warm from their exploration of her deepest most sensitive flesh. 'You may sit up now, my dear, you have done well.' Karen sat up but continued licking at the still sticky, salty, fingers. 'That will do my dear slave. You need to go back to your room and rest. You still have lots to learn before I present you to our guests.' Greta stood up, heavy tits swinging as she moved to pick up a robe to cover her nakedness. She was pleased, very pleased indeed, with the progress she was making. Karen had already done well in her early training but this little session had provided Greta with a lot of pleasure, after all she loved to have her tits sucked, but there was something even more pleasurable. Karen had shown her truly submissive nature. She had willingly spread herself unresistingly while she had been tested to her limits. Greta knew that Karl would be pleased. and she knew that, although the use of straps and other bondage would form a major part of their tormenting of Karen, the fact that she would willingly submit and offer herself would also give them some pleasurable times, especially when they were entertaining their guests. After all, it was not always possible to have the full facilities of the dungeon on every occasion and a slave who willingly submitted in this way was an invaluable asset.
