I awoke the following morning to find my cock growing hard in Monica's mouth. I pretended to be asleep and lay quietly feeling her mouth suck my thickening meat. She sucked it so lovingly and so patiently, not as if she had a goal of making me come quickly, but as if she was simply intertaining herself. When my cock had hardened completely she kissed her way down the shaft to my balls and taking my cock in her hand began to kiss and suck at my balls with the same kind of patience she had shown with my cock. Her hand slowly moved up and down the shaft as her kisses eventually moved below my balls and she began to lick and suck at my asshole. Although I tried my best to be unresponsive, wanting to allow her to continue for as long as she wished, her touch soon became more than I could stand and I began moving my hips, giving away my awakened state. While I'm sure she knew I was awake she never looked up and kept trying to insert her tongue in my ass as her hand slid up and down my cock. Her strokes kept time with the movement of my hips and as I felt myself growing nearer and nearer to orgasm they increased their speed appropriately. Finally the warm spunk she had coaxed from my balls shot up through my shaft and shot out onto my belly and her pumping hand. She continued to lick and press her tongue at my asshole while her hand milked my cock, draining every drop of cum from it. When my cock began to soften she raised her head and looking in my eyes began to lick the cum from her hand hungrily. Having cleaned her hand her mouth moved to my belly where her tongue licked out at the gobs of white cum which lay there. When she had gotten it all she crawled up over my body and lay atop me, kissing my neck and breathing in my ear, "Thank you, MASTER, for your cum." We lay in bed for a long time that morning, both of us reliving the previous evenings excitement in our minds and thinking about what lay ahead. "How did your evening with Tony go?", I asked. "Ohhh, MASTER, your friend Tony was very kind to me! He used my mouth all night long until he finally fell asleep. The first two times he simply let me suck him, but then he began fucking my mouth while he lay over me, humping his hips and thrusting his big dick into my mouth as if it were a cunt!", she explain excitedly. "And he also let me play with myself while he was using my mouth...he's a very nice man." "I'm glad that it went well, sweet slave," I said with a knowing smile, "were you able to sleep any at all?" "Yes, MASTER, I slept for a couple of hours, and when I woke up I wanted your cum so much. I hope you didn't mind me sneaking in here as I did." "No, you did fine, darling girl. I'm sure Tony will be out for another hour or so anyway. He's not used to having evenings like he had last night, I'm sure." Monica and I showered together and I laid out her clothes for our morning with my friends. I had chosen something which would be in once sense a bit demure when I had allowed her to wear the dress the day before, but now that she had been properly introduced to my friends as the slave-slut that she was, there was no need for as much clothing. I picked out the black garter belt, the black seemed stockings and the black high heels and laid them on the bed. I watched Monica dress with delight. She had taken readily to all the training I had given her and the results were certainly paying off. I had made a tape many years ago which was a compliation of women putting on stockings. As a part of her training I had allowed Monica to watch the tape and learn the proper way to hold her leg up and out and the way to point her toes as she slid each stocking up her leg. She had learned the importance of smoothing the stockings out with her hands and how to attach the garters in the most seductive of ways. And last, but not least, she had learned how to stand and turn before the full length mirror, making sure that the seams where straight in back. I knew, and Monica was learning quickly, that the key to being a really good slave-slut was in paying attention to all the little details. She busied herself in the kitchen, preparing our breakfast while clad only in the garter belt, stockings and high heels. Slowly the other guys began to stir and to come in for their morning meal. After breakfast, we retired to the living room while she cleaned up the kitchen. We discussed the previous evening and of course Mark and Jack were anxious to hear how Tony had enjoyed having the sexy slut in his bed for the whole night. Tony grinned like a Cheshire cat and told us about the use he made of Monica's very willing and seemingly insatiable mouth. It was obvious that the other two guys were envious and were hoping that their turn would come as well. "Are we going to get a chance to have her for the whole night too?", asked Jack. "Well, in order to be fair about it, I want each of you to be able to spend a night with her in your bed, the only competition today will determine which of the two of you gets her tonight and which one will have to wait until tomorrow night". I explained. "And how will we decide that?", Mark asked. "I've invented a little electronic device that I think may prove helpful with that," I said. "I call it a slut meter, and it measures the strength of a slut's orgasms. At one point in the day we will connect Monica to the slut meter and allow you and Jack to see which of you can provide our little slave with the strongest orgasm. The winner of that contest will have her in his bed tonight." "Where did you ever come up with an idea for such a thing as that?", Tony asked. I smiled proudly as I explained. "Several years ago I was invited to a party by a friend who lived in California. This friend was a Doctor who was doing research on the muscles and their response to different kinds of stimuli. He showed me the device that he used and the way that he attached it to lab animals. It was really a rather simple device, mainly a series of electronic leads with sensors which attached to different parts of the animal's body and a meter which registered the movement which those muscles made. It was only after I met Monica that I began to get the idea for using such a device in measuring her orgasms. She isn't aware that I have such a thing, but she will soon know." "Its a bit early for that though," I said. "We have some other things to do before we get started on that portion of the days activities. Are you guys too worn out from yesterday for more sex now, or are you still as randy as ever?" "Seeing Monica in that black garter belt this morning is all I needed to make me ready for more sex," sighed Jack. "Me too!",echoed the other two men almost simultaneously. "Good! I know Monica would be disappointed if we spent too much time today ignoring her. She's having a wonderful time." Calling Monica in from the kitchen, I motioned for her to sit in the straight backed chair I had positioned in the front of the room and stood behind her as I spoke to my friends. "By now I'm sure you're aware that Monica is an extremely oral little slut who loves to suck cock and loves the taste of hot cum spewed into her mouth. There are still some things, however, that you don't know about Monica. One of those things is how much pleasure it gives me to see her perform in front of other people, and how accomplished she is becoming at it." "Monica's training is not complete yet, by a long shot, but she has learned alot about the art of being a slave, and you will notice that as she sits before you her legs are opened wide and the lips of her trimmed cunt are easily observable. You will also notice that her hands are behind the chair as if they were tied there, and that the positioning of her hands causes her breasts to push out toward you and gives you a good view of her nipples." "I want her to give you a more complete view of her private parts than you have at the moment, even in her current position. Monica dear, stand in front of Tony and show him how hard your nipples can become." Monica obediently walked over to Tony and standing as closely as possible to him, began pinching and pulling at her nipples. Her eyes were focused directly on his eyes as her fingers worked on her nipples. "Monica loves to have her nipples pinched really hard. As you will see later on during the weekend her nipples can withstand a great deal of pressure and her pussy gets very, very wet when they are played with and used. Now...let Tony pinch them, Monica." Monica reached out and took Tony's big strong hands and placed them on her breasts. She kept her hands on his wrists as he kneeded her soft flesh in his palms and pulled her breasts out away from her body. "Roll her nipples between your thumbs and forefingers, Tony", I instructed. He did as I had asked, and as his fingers tweaked and twirled the hard nubs Monica's head rolled back and her eyes shut. Her hands were now rubbing his arms gently as he pinched and pulled ever harder on her lengthening nipples. "Now, Monica dear, move over to Mark and let him see just how wet this has made your little dirty tramp slut cunt." Reluctantly she removed Tony's hands from her breasts and moving directly in front of Mark she stood with her legs open. Reaching between her legs with both hands she gripped the outer lips of her cunt and pulled them outward, exposing the inner part of her now dripping wet hole. "Mark, notice how wet the stimulation of her nipples has made her. Look how the juices are thick inside her inner lips and how they have leaked out onto her thighs." Mark eagerly bent down and looked closely at Monica's open and exposed cunt which she so compliantly held open for him. "Pinch one of her nipples and watch as the juice begins to almost run from her hole." Mark reached up and took her left nipple in his fingers and began to pinch really hard. Momentarily he chuckled softly as the cunt juice bubbled in her middle fuck hole and began to drip onto the carpet between her legs. "Now, Mark, take your free hand and thump her clit with your middle finger. Thump it as if you were playing caroms and trying to shoot the "shooter" carom across the board. Thump it really hard." Holding his middle finger back with his thumb, Mark moved his hand close to her pussy and letting it fly with great force watched as the tip of his middle finger smacked her hard clit with an audible smack. Monica's body jerked and her head rolled back and then forward again. "Thump it again, harder", I instructed. Quickly, Mark once more thumped the little slut's clit, this time eliciting a moan from her and causing her to bend her legs a bit at the knee. "Doesn't that hurt?", asked Jack. "Does it hurt, Monica?", I asked teasingly. "Yesssss, MASTER, it does hurt, very much!" she breathed. "Do you want us to stop doing that, Monica?" I asked. "Nooooooo, MASTER, pleasssse don't stop thumping my hard slut clit! It makes my pussy tingle so!!!" Smiling at the three of my friends I told Mark to continue thumping her clit and to note what happened to her juice flow as he did. I also suggested to Tony that he take over from Mark and pinch both of Monica's nipples for her while Mark was thumping her. Monica's fingers were pulling at her cunt lips now, stretching them and rubbing them. "Monica, let Mark slide the fingers from his free hand up your twat now and reach back and expose your asshole to Jack by pulling open your ass cheeks. Jack, why don't you move around behind her so you can see how her ass cheeks clinch everytime Mark thumps her clit? You might also notice her asshole opening and closing." Jack moved around behind the now trembling little slave and watched as she spread the cheeks of her ass open wide, allowing him to see her asshole plainly. Mark began inserting his fingers in her deliciously juicy cunt and pumped them in and out of her as he continued to thump her clit with the middle finger from his other hand. "Ohhhhhh, MASTER!!!!...it feels soooooooo good!!! Please may I have something in my ass MASTER?" "Wet your finger with some of the juice on her thigh and slide it up inside her ass Jack. I'll get something she'll like even better than your finger while you get her lubricated." Having said that, I walked to the bedroom and returned with the small dildo which Monica had become accustomed to having placed in her ass each night before she was allowed to sleep. Handing it to Jack I instructed him to insert it slowly after coating the tip in some of the juice that was puddled on the floor between her legs. "Thats it, now fuck it in and out of her ass like a cock...she loves it!" "Unnnnngggggh!!! Yesssssss!!", Monica moaned as she felt the dildo being fucked in and out of her ass. "More!!!...please give me more!!!!" The sight was more than I could bear and I took my throbbing cock from my pants and began to stroke it as I watched the three men using my nearly naked wife in front of me. Her head was rolling in small circles now and her moans and cries came nearly continuosly now. I knew her orgasm was not far away. She stood with her knees bent and her hips fucking back and forth on the hard intruders in her cunt and ass. Tony's fingers were pulling and pinching her hard nipples violently now as the other two men fucked her. "Pleassssssse MASTER!!! may I come now??!!! Pleasssssse!!!" My own orgasm was not far away either, and I was silent only for a moment before shouting out breathlessly, "Yes, precious tramp slut whore, come for the men who are watching and using you! Come like the trembling fuck hole that you are!! Come NOW!!!!" Her fingers dug hard into the cheeks of her ass and her hips pumped even more rapidly as the moans she had been emitting turned into a high pitched scream. Her extremely strong orgasm washed over her like a tidal wave and in the middle of it she lost her balance and had to reach out to grab the shoulders of Tony and Mark to keep from falling. As her passion slowly subsided she stood erect once more and placing her hands behind her head her breathy voice asked weakly, "MASTER, may I sit?" "You may kneel in front of me and lick up the cum that I spilt on my thighs and stomach, Monica. And when that is done you may rest." The four of us sat quietly while Monica completed her assigned task. We had all been witness to a very special moment. A moment which would normally be a very private moment for a woman, but which for this woman had been shared with four men. When she had finished licking up my cum she sat in the submissive position she had been taught in the floor at my feet, her head bowed. For a long time none of us spoke, to a man we were all still a bit in awe of the passion we had just witnessed. And we knew there was more to come. --
