Rebecca lounged lazily on the plush couch, flipping through channels on Jack’s satellite TV. She was wearing one of his large t-shirts and a pair of white low rise panties. She liked when she visited and had the place to herself, since she was allowed to lounge around and be comfortable. School was on break, and at Jack’s allowance, Melanie had brought her back home to stay with them for a couple weeks. She stretched out, wondering when Jack and his wife were coming home from dinner. Jack had promised her a wake-up fuck the next morning, but she wanted to make sure his wife was still getting up early to go holiday shopping with Melanie and Sara. The last thing Rebecca needed was Jack’s wife catching them fucking. She yawned and, thinking about the morning’s prospective activities, her body began to tingle. Sometimes she hated how horny she could get at the drop of a hat. Especially when it happened late at night when she was tired; it meant she wouldn’t get to sleep unless she had a good cum or three first. She licked the tip of her fingers and gently rubbed her clit. She became wet instantly at the touch. She closed her eyes and though of her Master, Sara, and Jack. She wished Sara and Melanie had a closer relationship, and the thought of fucking both sisters at the same time caused Rebecca’s breathing to become deeper and her rubbing to become faster and harder. She wondered what Jack would think of the idea; she already knew what her Master would think. Over the years Rebecca had become good at determining what her Master would like- and at delivering it to him. With images of the sisters, naked and entwined in sweat and cum, dancing in her head, Rebecca came while rubbing furiously at her clit. She exhaled deeply, removed her hand from her panties and in moments she was fast asleep. She awoke to the sounds of voices; female and male. She recognized Jack’s voice; it was distant, but even in her half-asleep state she knew it was him. The voice was deep, guttural, animal, and came in grunts and groans. Rebecca recognized the sound of Jack fucking. The lights in the living room were out, and she’d been covered with a blanket. Obviously they’d come home from dinner and found her, covered her so she wouldn’t be exposed when Melanie or Sara came home, and then proceeded to their bedroom for a good romp. She wanted to envy them, but instead she stretched her limbs and padded quietly into the bathroom to rinse her mouth; she always had a nasty taste in her mouth when she woke from sleeping. As she passed the master bedroom, she peeked through the open door. Jack's wife wasn't what Rebecca would call beautiful, but there was a certain spark about her personality. She could see why Jack had married her, but she could also see why Jack cheated on her. With Jack's wife, sex was almost a chore; something he did more for her than for himself. It's not that he didn't enjoy it; it just didn't always give him what he needed or wanted, sexually and physically. Rebecca supplied that for him. Rebecca supplied that for a couple different men, including her Master. She'd often thought about operating her own 'business' but would rather be a slut than a whore; she’s never once taken money or goods in exchange for sex. She wouldn’t turn down a dinner date or a trip to the theatre, but she never considered those payments for sex; they were gestures of friendship and simply a part of the relationships she had. She padded into the bathroom, creeping carefully as to not disturb Jack and the missus, and brushed her teeth, rinsing the taste of sleep from her mouth. She washed her face, and combed her hair, and even took a moment to check on her pussy, touching up the shave job. She liked to keep smooth, and recently she has given Sara the order never to be caught with a single shadow of a pubic hair. She licked her lips thinking about Sara, and left the bathroom, stepping slowly down the hallway. Jack was still banging his wife. The woman’s noises were getting louder as Rebecca crept down the hallway. She turned back, and peeked through the doorway where the door was pulled just-to. There was Jack, poor sweating Jack, between his wife’s legs pounding away steadily as she begged him not to stop. Rebecca could see the side of his face; he looked bored. He didn’t have to mask it – his wife liked being blindfolded during sex, it was the only “kinky” thing she did. She seemed to be having a nice time, however he seemed as if he were doing a menial household task. Jack had told Rebecca once that his wife was hard to bring to orgasm. Sometimes it would take an hour just to get her close. Rebecca knew it was no fault of Jack’s- he was pretty skilled in the bedroom. Without thinking about it, Rebecca pushed the door open quietly and slunk inside, her bare feet making no noise on the plush carpeting. She knew Jack’s wife couldn’t see her, but she stepped quietly, wanting to surprise Jack. With a silent quickness that only comes from practice, Rebecca stripped naked then came up behind him, and pressed her breasts against his back. “Shhhh,” She whispered in his ear. “Pull out.” Jack wasted no time, and his wife’s whimpering began almost immediately. She reached to pull off the blindfold, but Jack’s hand stopped her from removing it. He ran his hands up his wife’s arms and held her wrists above her head on the bed and gave her a gentle kiss. Rebecca licked her lips and bent down on her knees. She placed her hands on the other woman’s thighs and when the woman gasped at the second pair of hands touching her skin, Rebecca smiled. “No, Jack! What are you doing to me? What is going on?” She squealed and writhed on the bed, but her husband held her firmly in place. Rebecca slowly ran her tongue along the quivering thigh before her, drinking in the taste of sweat, sex and protest. Jack continued to hold down his wife while Rebecca drove her tongue into the defiant woman’s just-fucked cunt. She licked hard and slow, working her way to the top of the slit. Using the tips of her teeth, Rebecca nibbled gently at the married woman’s inflamed clit, and then sucked it hard, flicking it with the tip of her tongue as she sucked. It was a technique she used when giving head and it usually went over well with the men. Jack’s wife also seemed to enjoy it, and within minutes Jack’s wife was crying out in orgasm. Rebecca never let up, she sucked and licked Jack’s wife into two more orgasms before licking her lips and coming up for air. She smiled at Jack, and whispered “You owe me a fuck” into his ear before grabbing her clothes and walking out of the bedroom. She pulled the door closed as she left. Sara has come home from a friend’s house and had heard her parent’s fucking, and heard her mother cum three times. But, when she saw a naked Rebecca walk out of her parent’s bedroom, she gasped silently. She wondered if Rebecca was fucking her whole family. Rebecca smiled at Sara. “You dad was having a hard time. I helped; it’s what I do.” Sara shook her head, unbelieving. “Maybe you just need to calm down? I know I need to cum; the taste of girls never fails to get me going. We can go to your room.” Rebecca looked questioningly at the girl, her eyes dark but happy. “I can’t! My mother is home!” Sara began to protest. Like mother, like daughter, Rebecca thought. She grabbed Sara by the arm, “Come on. Your mom isn’t in a position to say anything right now.” The fifteen year old didn’t want to be defiant, and allowed the older woman to drag her to her bedroom. Rebecca flung Sara at the bed, and smirked as she tumbled off, landing at an odd angle on the floor. “Get back on the bed.” Rebecca’s voice only held command; no hint of the playful tone from the hallway was there. Sara lowered her eyes, obeying. She crawled back onto her bed and looked to Rebecca for further instruction. “Take off your clothing, place them away from the bed so they can’t be stepped on. Lie on your back, legs open, knees up, then close your eyes and don’t say anything.” With those words, Rebecca left the room. While Sara undressed, Rebecca moved back towards Jack’s bedroom. She turned the knob quietly, and pushed the door open. She could see Jack comforting his wife, cuddling her and smiling. She eased in, crept behind the bed, and then placed a hand on Jack’s shoulder to get his attention. He turned his head slightly, and Rebecca whispered in something in his ear. He smiled, nodded, and then turned his head back to his wife, who was so involved in her own worries about having someone other than her husband in the bed with her that she never noticed that Rebecca came and went. Back in Sara’s bedroom, the young girl was exactly as Rebecca had ordered her to be. Rebecca smiled and as she entered the room, kept the door open and stood off to one side of the bed. A short time later she heard footsteps in the hall, then two figures entered the room: Jack, and his wife, whom he had by the hair. She was blindfolded again and whimpered softly. Jack led his wife to the bed, and shoved her head forward. “Now, return a favor, for the cums you had, darling.” Jack spoke softly. His wife opened her mouth wide, expecting a cock, and was shocked enough to pull away when her mouth was placed against a wet, hairless cunt. “Lick.” Jack was firm, and placed his wife’s lips against his daughter’s sex. His wife gulped heavily, but gingerly licked the cunt before her. Jack addressed his daughter, though not by name. “Spread them, baby.” His wife heard the softness in his voice when he spoke to whoever was on the bed. Sara had heard her mother cum earlier, and knew who was licking her under-aged cunt, and grew more moist by the second. She squirmed in place, but continued to keep her eyes closed. Rebecca sat against a wall and rubbed her clit, enjoying the forced incest. She couldn’t wait to take this story back to her Master. She looked at Jack and saw his cock growing at the sight. His wife still had to be held in place, and was not enjoying herself at all, but the woman could tell that whoever was on the other end of the cunt she licked was at least aroused enough not to lay still. Rebecca stood and walked over to the bed, crawled on top, and sat on Sara’s face, muffling her whimpers. Sara bucked and quivered; her lips and tongue moving to ensure Rebecca’s pleasure. Sara breathed heavily, pulling her mouth away from Rebecca’s cunt, exclaiming with pleasure, “Oh mommy!” as she came. Jack’s wife pulled away from her daughter, clawing at her blindfold and scrambling to get away from the bed. “Oh, God, no!” Jack had watched as his three lovers had sex. Finally, he couldn’t take it anymore, and he pushed his hysterical wife aside, and thrust into Sara. His wife panicked, tried to tear Jack off her little girl, crying and screaming, but Rebecca jumped off the bed and grabbed the missus by the hair. Rebecca jerked Jack’s wife’s head up, facing her towards her family on the bed. “Watch them. Watch how your husband plunges into his little girl, his baby. Her tiny cunt filled to the brim with his hard cock. She begs for it, longs for it. She loves her daddy, especially when he’s dumping a load of cum into that sweet little cunt of hers.” “What the fuck are you doing?” Jack’s wife had tears in her voice. “Fuck me, daddy. Cum in your baby!” Sara moaned, oblivious to her mother’s screeching antics. Jack pounded harder, picking Sara’s hips up in his strong hands and bringing her body onto him as hard as he could. Rebecca smirked at Jack’s wife, “If you need to come again, I did like the taste of your cunt.” The older woman gasped. Rebecca giggled. Sara and Jack came. Sara opened her eyes and smiled at her daddy, and thanked him. “I guess we should explain?” Rebecca smiled as she spoke. Jack’s wife wasn’t sure she wanted to hear the story, but listened anyway. She found herself partially aroused, but mostly sickened by the fact that her daughter was being fucked by her husband. And Melanie’s school friend was helping? To make the story easier to handle, Jack held his wife down on the bed, against much protest. Rebecca caressed the restrained woman’s body as she told the story, and young Sara showed her mother how Rebecca taught her to lick pussy. Sara used her fingers to keep her mother’s cunt spread wide, and dipped her tongue as deep as she could before extracting it, and drank in her mother’s juices. Despite the wriggling and mumbled “stops”, Sara’s mother was enjoying herself. She came four more times at her daughter’s mouth, and the little girl drank it all in, then gave her mother a kiss and thanked her for the opportunity to please her. When their story was done, Jack’s wife knew all about Rebecca, her Master, her affair with Jack and the corruption of her 15 year old daughter. She didn’t know everything Sara had done, and Rebecca never told her what was still in store for the young slut, but she came to terms with it, and accepted it was happening.
