John switched off his computer and turned off the light. He was anxious to get out of the office and on the way home. It was Friday night, it was his birthday, and Kelly had promised him a surprise. He wondered what she had in mind--he knew it wasn't dinner and a movie. Kelly rarely came up with anything that pedestrian. Kelly had called earlier in the day and left him a mysterious voicemail. She'd said simply, "Happy Birthday, darling. I have a surprise for you. Be home at 6." It was five minutes to six when he pulled up in the driveway. John strode eagerly in the back door and into the kitchen. "I'm home," he called. Silence greeted him. His heart dropped into his shoes. He'd been so excited to get here, now where was she? John finally noticed the note propped up on the kitchen table. Grabbing it, he read, " Happy Birthday! Please go upstairs, take off all your clothes, and put on your bathrobe. You can shower if you feel like it. Wait for me in the bedroom." John grinned. He knew his "surprise" would have something to do with sex. It had been a rough day at work, but just the thought of rolling around with Kelly gave him new energy. He bounded up the stairs and into their large master suite. He looked for Kelly, but she was nowhere to be found. He had noticed that the door to her office was closed. Maybe she was in there putting on lingerie or something. The thought made him shiver with anticipation. He decided to shower. Toweling himself off, John walked into the bedroom to see if Kelly was there yet. She wasn't, but she obviously had been. The lights were all off, and it looked like she had enough candles burning to start the Chicago fire. A light scent of sandalwood wafted through the room, and he could hear some faint music coming from down the hall. John finished drying himself and pulled on his bathrobe. He sat down in a large green overstuffed chair to wait. Just as he was starting to get impatient, Kelly came in. She was wearing a black G-string with a white bow attached. Not a fabric bow, but the kind you put on presents. Her breasts were uncovered, but she wore a thick leather collar around her neck. One end of a leather leash was attached to a D-ring at the front of the collar; the other end was in her hand. She came to stand directly in front of him. It was obvious that she was embarrassed. Her eyes never left the floor, and he thought he could detect a slight tremor in her lower lip. She raised the hand holding the leash. Her hand shook as she offered it to him. "Until dawn, I belong to you. I will serve you any way you wish," she said softly. John stood and took the leash. He pulled her toward him and held her in his arms for a minute. This was something different. He and Kelly had played bondage games before, but this was the first time she'd ever offered to be his slave. He wondered where she'd bought the collar. Now, of all his fantasies about what he'd so with a sex slave, which to make come true? John let Kelly go. He pulled down on the leash while pressing down on her shoulder. Kelly understood and sank to her knees. John hurriedly pulled his bathrobe open and pushed his now-erect cock toward Kelly's face. She took it tenderly in her hands and began to run the tip of her tongue up and down its shaft. Crouching down further, Kelly moved to lick at his balls, taking each one in her mouth and sucking gently. He loved it when she worshipped his cock that way. She truly seemed to enjoy licking and sucking at him. He let her nibble at him for awhile, relaxing into the sensation. Suddenly, John had an urge to express his authority. Pulling up on the leash, John raised Kelly to her feet. He pulled her behind him toward the bed and pushed her down on it rather roughly. "Lay down, slave, I'm going to fuck your mouth." The ghost of a smile crossed Kelly's face, but she obediently laid herself across the bed, her head slightly hanging off the side. John moved to stand over her and put his cock at her lips. Kelly was one hell of a cocksucker, but she'd never quite managed to get that last inch of his large cock into her mouth. Tonight he'd see that she did. He pressed forward, sliding his cock between her lips. "Don't bite now, or scratch me with your teeth " he said, "or I'll have to punish you." Her eyes widened. He could see both fear and excitement in them. She obviously hadn't thought far enough to realize punishment was part of being a slave. She tried to say something, but he held his cock in her mouth, making speech impossible. Little by little, his cock disappeared into her mouth. He held it there, watching her try to breathe. He knew that when he put it in far enough, it cut off her air, leaving her totally helpless. He pulled it out a bit whenever he thought she needed oxygen. And each time he pushed back in, he pushed a little farther. Kelly seemed to be into it. He could see that she was trying to relax her throat muscles to take him in all the way. He kept hitting the back of her throat though. John held Kelly's head and tipped it a bit to get a better angle. With a firm push he sank his cock to the hilt. Kelly's nose was in his pubic hair, and he thought he could almost see the outline of his cock in her throat right above the leather collar. He pulled back a bit to let her take a breath and sunk it back in. Soon they'd established a rhythm where she could breathe and he could get his cock all the way down her throat. It felt warm and tight down there. It made him excited. He picked up his pace, fucking her mouth deeply and rapidly. As he came close to orgasm, Kelly suddenly twisted her head, dislodging his cock. He was furious. She had stopped him just at the point of orgasm. This was not how slaves were supposed to act. John grabbed the leash and jerked her upright. "What the hell was that all about? I think you're forgetting who's in charge here." "May a slave make a suggestion, sir?" she asked. John sighed. Kelly always tried to top from the bottom. He was tempted to just gag her, but she usually did have good suggestions. Plus, gags didn't work very well for blow jobs. "What?" "Well, I was thinking that you might want to enjoy your slave for a little longer than 10 minutes," she said hopefully. Had it really only been ten minutes? John looked at the clock. He knew what she was up to. He usually lost interest in sex for at least an hour or two after coming. She wanted to make sure he was going to stay interested enough to take care of her. He could see that she was getting hot playing a slave, even if she wasn't a very practiced one. Well, it was probably time she learned that slaves don't make the rules. Maybe he wouldn't even let her come tonight. On the other hand, he did want to prolong the scene. John looked at Kelly sitting on the bed. Her face was flushed and she had that glazed look in her eyes that she always got when she was really turned on. He noticed that she had one hand in her crotch and that her little G-string was sopping wet. The bow had disappeared. "Get your hand away from there," he told her. "You're supposed to be pleasing me, not yourself. Go get some massage oil. And warm it up." He let go of her leash, and she padded off to the bathroom, the end of the leash thrown over her shoulder where it bounced against her ass. He heard water running as she warmed up the massage oil under hot water. Kelly came back into the room holding a bottle of massage oil, leash still over her shoulder. "What do you want me to do?" John relaxed back onto the bed. His erection had subsided a bit and he no longer felt the urgency to come. "Come here and massage my cock," he told Kelly. Kelly grinned. This was one of her specialties. He gave her a stern look and watched her struggle to adopt a subservient expression. It was a battle; being submissive did not come easily to Kelly, much as she loved it. He watched as she poured some massage oil into her hands. She rubbed her hands together briskly, which made her small, round breasts jiggle delightfully. She crawled over toward him and gently laid her slippery hands on his cock. With smooth strokes, she spread the oil around until his cock and balls were covered with it. John reached out and took the end of the leash in his hand. Then he sighed and closed his eyes, losing himself in the sensation of her warm hands stroking him. Until he'd met Kelly, John had never had a cock massage. It was a wonderful experience, curiously nonsexual and sexual all at the same time. Kelly stroked up the underside of his scrotum, gently cradling his balls in her hands. She ran her hands up the sensitive folds between his legs and his balls. She pulled on his cock, rubbed it between her hands, and massaged the tip with her thumbs. He looked at her through half-closed eyes. She seemed to be enjoying herself as she stroked him, his cock hard sometimes, sometimes not. She'd explained to him that relaxation, not orgasm, is the purpose of a cock massage. John didn't want to get too relaxed. He let Kelly continue to massage him for awhile, then he pulled on the leash and brought her head up even with his own. He kissed her fiercely and whispered in her ear. "You're going to put on a little show for me now." She squirmed. Kelly was basically shy about her sexuality. It had taken him quite awhile to get her to masturbate in front of him. Frequently, she couldn't even come because she got so self-conscious. He had a feeling she could get herself off tonight, though. And he wanted to watch. "Get the big dildo. And your butt plug," he commanded. And then go sit in the chair." John adjusted the pillows on the bed so he would have a good view of what went on in the chair. He loved watching Kelly come. And she had given him a very nice cock massage. She deserved an orgasm or two. Or three or four. Kelly was insatiable once she got started. Maybe he'd just sit back and watch her do all the work. Then she could finish him off. Kelly rummaged around in the closet and came out holding a wooden box. Their "toy chest" held their collection of sex toys, which seemed to grow larger every month. She opened the box and selected a large dildo and a smaller butt plug. Her leash dangled from her collar, the leather lying between her breasts. The end dangled almost to her knees. She sat in the chair and awaited his instructions. "Play with your tits, " he said. Kelly closed her eyes. Playing with her tits in front of him really embarrassed her. He wasn't sure why, but she'd told him it seemed even more intimate than fingering herself. She began to squeeze her breasts softly, running her fingers lightly over her nipples. Kelly's nipples were very large for her small breasts, and they were very sensitive. She claimed that she could feel it in her clit when they were touched. "Do it a little harder, "John instructed. You know you like to have your nipples pinched harder than that. And look at me while you do it." Kelly squeezed harder, opening her eyes to catch his look. It was hard for her to hold his gaze. Kelly'd always made love with her eyes closed before she met John. He taught her to keep them open, but she just couldn't when she was embarrassed or about to come. Pinching her nipples firmly, she tried to look at him. He could see that the stimulation was turning her on even more and that her G-string was getting soaked from the moisture gathering at the entrance to her pussy. "OK, take off your G-string now." Still staring at him, Kelly wriggled out of the small piece of cloth, revealing a smoothly shaven pussy. There wasn't a hair on it anywhere. Usually she left at least a small patch. Grinning, John stroked his cock, which had grown to huge proportions. He wasn't sure how much more of this he was going to be able to watch. "Spread your legs." Kelly spread her legs wide as she leaned back into the overstuffed chair. He could see right into her pussy. But he was too far away. He wanted to taste it. He moved across the room and knelt between her thighs. He wanted to snuggle down between her legs and slowly probe her pussy with his tongue. He loved the feel of the soft skin on the inside of her thighs. He let his mind go blank, trying to connect with her body. Listening to her breathing, he was alert for building tension. Her breasts were soft and smooth under his hands as he gently pinched and played with her nipples, which hardened immediately. Kelly relaxed her legs, letting them spread wider, welcoming John into her pussy. Soon, he knew he was in control; that she was letting him guide her body's response. John liked to bring her right to the edge of orgasm and hold her there. It made him feel like he owned her body and that her mind was completely consumed by erotic thoughts. When she reached this point, she could take an amazing amount of stimulation. He gently pulled open the folds of Kelly's pussy to make her clit stand erect. John put his lips on it and sucked it into his mouth, rolling it around firmly with his tongue as Kelly moaned and thrashed in the chair. He released her clit and drew back to look at it--it was deep red and swollen huge. She was almost ready. It would take only a couple flicks of his tongue to bring her to orgasm. He took his time, savoring the taste of her pussy, the softness of her skin, and the cute little whimpers she always made when he ate her pussy. He reached out his tongue and placed it lightly on the tip of her clit. She moaned wildly, her hips bucking up at his face. He flicked his tongue across her clit and then sucked on it. He felt her throbbing beneath him as she began to orgasm. He kept his tongue on her clit, stoking lightly as she continued to come. Finally, she stopped heaving and reached down to push his face away. "No more. Wait," she said. John leaned back, grabbed a towel, and wiped off his face as well as sopping up some of the moisture around Kelly's pussy. Then he reached up and hugged Kelly, kissing her, letting her taste herself. Remembering that he was supposed to be the master, John stood up and walked back over to the bed and laid down. "Put your butt plug in." "By myself?" she asked incredulously. "Yup. Here." He tossed her a bottle of lubricant from the bedside table. Her face was red, he noticed, and wondered if it was from embarrassment or desire. But she took the lube and smeared some on her little butt plug. Then she bent over with her ass facing him, and worked it in. Her ass was too much to resist. John got up off the bed and reached for the end of the leash. He pulled Kelly back over to the chair and leaned her over its rounded back. She started giggling, but stopped quickly in surprise when her smacked her butt. He smacked it a little harder. Her cheeks turned pink, and she wriggled her ass at him. This obviously wasn't hurting her. He slapped it a few more times, then put his cock at the entrance to her pussy. "Yes," she whispered. "Fuck me." John twisted the leash around his hand a few times and pulled her up part way. "I'll fuck you when I'm good and ready. And this is for being an uppity slave and pulling your mouth off me when I was about to come." He smacked her butt again, a little harder this time. After all, what did she expect if she was going to lean over the chair back and wiggle it at him like that? But he really did want to fuck her. After all, it was his birthday. John brought the head of his cock back to her pussy and poked it part way in. He like to tease her by just slipping in a couple of inches. He knew it drove Kelly crazy because she always went into a frenzy trying to get more of his cock inside her. Tonight was no exception. He watched her wriggle her butt, vainly trying to back onto his cock. Holding her hips, her prevented her from moving very far. Then he reached around her and found her clit. As he began to massage it, he slowly pushed his cock into her dripping pussy. Her pussy was so wet and slick. He could see the moisture starting to run out onto his cock. Playing slave was clearly doing something for her. She twitched, and shuffled her feet around on the floor, trying to get enough leverage to be able to fuck him back. But he bent her further over the chair back so she only reach the floor with the tips of her toes. As he watched his cock sliding slowly in and out of her pussy, he reached for her butt plug and began to slide it in and out as well, pausing occasionally to reach under and stroke her clit a bit. Kelly went nuts. She started moaning and gasping and wriggling and grasping at the chair fabric. He loved watching her when she was like this. She was better than any porno actress once she lost control. And she was definitely out of control tonight. She soon came, and her pussy grasped his cock so hard he thought he'd explode himself. But he held on. As Kelly's panting subsided, he withdrew from her pussy, and pulled her upright. Placing her gently in the chair, he strode back to the bed and sat down. She just looked at him, glassy-eyed. "Now, fuck yourself with the big dildo until you come." "But, I just--" "Just do it, Kelly. You can. Your pussy is so wet you probably don't even need any lube. I know you can come again." Kelly reached down to the floor and grabbed the huge dildo. She slid down in the chair and spread her legs wide. Her pussy lips were bright red and swollen, and he could practically see her clit throbbing. Bringing the dildo to her pussy, she began to work it in. Slowly at first, then increasing the tempo, she fucked herself. Soon she closed her eyes and one hand strayed to her breast, firmly grasping a nipple. Occasionally she reached down and fingered her clit. With her pussy shaved, he had a perfect view as she shoved the dildo in and out. After only a few minutes, she came again. "One more time, Kelly. You can do it." She started to say something, then stopped herself and brought her hand to her pussy. Leaving the dildo stuck up inside her, she concentrated on rubbing her clit. Less than five minutes later, she was coming again. "That was too easy, Kelly. You'd better do it one more time." "Oh, come on," she burst out. He could tell she was getting tired. "Just once more, Kelly, then I'll let you quit. Remember, you're my slave until dawn. You have to do what I say." She just looked at him. He thought he detected a glimmer of defiance in her eyes, but she slowly began to finger her clit again. She bounced up and down in the chair a bit, and he decided she was trying to get some stimulation from her butt plug. She pushed the dildo, which had slipped out, back into her pussy and turned on the vibration. She worked herself over, rubbing her clit furiously while she pushed the dildo in and out. It took her considerably longer this time, but she finally came again. Her hair was damp, and her skin shiny with sweat as she lay back in the chair exhausted. "That was very good, Kelly. Now come and fuck me." John laid back on the bed, his erect cock pointing proudly. He watched as Kelly removed the dildo and heaved herself out of the chair. The bed creaked a bit as she climbed onto it and straddled him. Holding his cock up, he watched as her pussy descended onto it. She began to move up and down, her breasts swinging gently as she bounced on his cock. John gasped as he felt her hand caress his balls. He knew he'd come soon, and he didn't want to wait much longer. But he wanted to see her come one more time. As she sat upright, sliding her pussy up and down on his cock, John reached up to touch her clit. It was still pretty sensitive from her last orgasm, and she jumped a bit when his fingers grazed it. Gently he rubbed just above her clit until he felt it get hard again. Then he increased the pressure. She tried hard to keep up her rhythm, but finally gave up and just sat on his cock while he fingered her. Her pussy clamped around his cock, and he could feel the butt plug up inside her. Just as she started to come, he let go of her clit and grabbed her hips, fucking her furiously. She screamed, arched back, then convulsed forward, falling onto his chest. He continued to pump while she came and came. When it seemed that she was finally done, he pulled his cock out of her pussy and rolled over on top of her. Straddling her, he stroked his swollen cock. Thick ropes of white come spurted out the tip and onto Kelly's face, tits, and belly. She smiled at him, one eye closed to avoid come running in it. The tip of her tongue reached out to lick come from her lips and chin. "Happy Birthday, darling," she said. "Can I have a towel?" John reached across the bed and picked up a towel. First he wiped off his cock. Then, very gently, he cleaned the come away from Kelly's eye and wiped her face. "You can sleep in the rest of it, my slave." Kelly just smiled and rubbed it into her tits and licked it off her fingers. "I'm exhausted, she said. "Can your slave go to sleep now?" "First let's blow out the candles." Still holding Kelly's leash, he made her follow him around while he extinguished the candles. He led her into the bathroom so he could pee, and held the leash while she did. Then he led her back to the bed, folded her into his arms and held her tightly to his chest, the leash between them, the end wrapped around his hand. Soon both were asleep. ****** The morning sun streamed in the windows when John woke up. He looked at Kelly sleeping beside him. Still naked, she was on her side turned away from him. He could see dried come crusted on her side where it had dribbled down from her breasts. Her leash, still attached to her collar, draped over her back. Blood rushed to his cock as he thought about last night's events. John reached down and picked up the end of the leash and wrapped it tightly around his hand. He pulled gently, and Kelly woke up, turning toward him. Her hair was matted with come, making her look sluttier and sexier than ever. "Morning." she smiled at him sleepily. "Did you have fun last night?" He looked at her and pulled down on her leash. "Suck my cock," he said. "Ha," she laughed. It's past dawn. I'm not your slave anymore. Maybe later. I'm covered in come, I need a shower." She moved to get up from the bed, but he didn't relax his grip on the leash. "Suck my cock, " he said softly, pulling more firmly. Kelly stopped and stared at him. He stared back, keeping the pressure on her leash. "But, our agreement was until dawn." "Suck my cock." They stared at each other. Defiance flared in Kelly's eyes. Suddenly her expression changed and she moved down the bed. John lay back and sighed as he felt her soft, moist lips engulf the head of his cock.
