You looked down at Sara and Rebecca, who were both on their knees in before you. They both wore only pony tails, and you smiled down at them. “Today, we are going to teach Sara some new tricks, yes?” You asked, circling them as you spoke. You lifted Rebecca’s head on your hand and looked into her eyes, willing your mind upon hers. “Yes, Master.” Rebecca answered, her eyes already beginning to glaze over. You take your cock in one hand, and stroke it a little in Rebecca’s face, and you can see her body tense and her breathing become deep. You place the head of your semi-hard cock on her lips. Obediently, she opens her mouth and flicks her tongue towards the head of your cock, and you lean forward, shoving it into her mouth. She closes her lips, and moans in her throat as the warm liquid begins to flow from you down into her belly. She swallows hungrily, her eyes lost in a sea of submission. “You love drinking piss, don’t you, you little piss slut.” “Yes, Master.” Rebecca said, after you withdrew your cock. She looked longingly at it. “What are you?” “I’m your piss slut, Master.” Rebecca’s voice was a trembling whisper, full of lust, longing and possession. You stroked your hand along the side of Rebecca’s face and gave her right cheek a soft slap. She shivered and moaned, leaning her face into your hand. You pushed her away, and stepped to the side, and your sub’s pretty blue eyes floated to the floor, lonely. You stood before Sara and glared down at the girl. She trembled slightly, unsure of herself. You shoved your cock into her lips, and she parted them slightly, licking the head and tasting remnants of the urine Rebecca’s didn’t clean off. The young brunette wrinkled her nose and backed away, licking her lips to remove the taste from them. You grab Sara’s pony tail and shove her face into your crotch. You told her to smell you, and you ran her nose along your sex, between your thighs, and you had to spread your legs a little as you stood there with her hair in your fist. You could hear her gulping, and felt moisture on your leg, so you tugged back on her head and saw a few small tears glistening down her face. Something inside you moved, tingled, at the sight of the tears. They are so beautiful. Even more so when they are streaming down the face of a fifteen year old over-sexed slut-in-training. However, you didn’t want to scar the poor girl, so you asked her if she would feel more comfortable with Rebecca helping her through the process. After the teenager nodded, you motioned for Rebecca to move over towards Sara, and she complied. It didn’t take you long to get them in the perfect position. Sara and Rebecca were facing each other, both kneeling, their bellies flat and touching. Their breasts pushed against each other’s and their faces were cheek to cheek, so that both girls faced you. Sara’s hands were around Rebecca’s waist, and were bound together; Rebecca had the same thing done with her hands around Sara. Then, you had looped an old belt around their waists, and pulled it taut, pushing the two females into one entity. Each one had her legs partially spread, and they were intertwined; Rebecca was kneeling over one of Sara’s legs, and Sara over one of Rebecca’s. Each girl leaked cunt juice onto the other’s thigh. Satisfied, you stepped back to look at your creation. Beautiful. You grabbed up your digital camera and took a few pictures, the girls trembling with desire at each click. Rebecca started to shake, her eyes closed and her breathing stopped. With flushed skin, she silently came and exhaled deeply. A quiet “Thank you, Master” followed. “You’re welcome, slut.” You said to her, loving how easily your little cum-bucket can gain pleasure from your activities. Setting the camera down, you walked over to the girls, and again stroked your cock into their faces. Both mouths opened, tongues poking through soft, wet lips, eager and welcoming your cock. You rested the head of your cock against Rebecca’s lips and let your piss steam out in a small burst. She opened wide, gulping, licking, trying to get it all in her mouth; but she didn’t swallow it. Instead she turned her head and kissed Sara, close-mouthed. Slowly, the older woman worked the teen into an open-mouth kiss, and with her tongue, pushed some of her Master’s piss into Sara’s mouth. The girl was so into the kiss with her older playmate that she eagerly drank down the warm liquid without thought or revulsion. You let more go, and the stream hit the girls as they kissed. They turned to you with their mouths open, and tried to lap up as much of the piss as they could as is streamed into their mouths, down their faces, and over their breasts. By the time you were done pissing on them, even their cunts dripped liquid gold. Rebecca turned to face Sara, and began to lick your piss off the younger girl’s face and neck. Cock still in hand, you jacked yourself a bit, feeling it grow at the sight of your mistress licking your piss off a fifteen year old. You needed to cum, badly. You untied Rebecca’s hands, and helped the girls to stand. Then, you laid Sara on her back on the bed, with Rebecca lying on Sara, still bound to her. They hung close to the edge of the bed, and you stood behind them. With a force driven by animalistic need, you shoved your hard cock deep into Sara and pounded her relentlessly for a full five minutes. You pulled out of the young one, and plunged deep into Rebecca’s cunt; it didn’t take long before the woman was silently cumming once again. You took turns pounding each girl for a few strokes, easing your cock from one wet cunt to the other, and eventually your need grew so strong you had to release. You undid the belt, untied Sara’s hands and rolled Rebecca off the pretty brunette. “I’m going to cum in you baby. First, I want you to cum for me, and then I’m going to cum in you. Do you know why?” You breathed heavily as you fucked her tight teenage pussy. She shook her head. “I’m going to fill your flat little belly up with my seed. What comes after that, little slut?” You pushed her further up on the bed, crawled between her legs and leaned down over her, so you could give her a small kiss on the lips. “I… I will get pregnant…?” She mused aloud, choosing the only answer that made sense to her at the time. Her breathing became harder as you pushed your cock deeper and deeper. You could tell she was getting close, so you continued on steadily as she grabbed your shoulders and threw her head as far bask as the bed would allow. Tears rolled down her cheeks as she came, and she moaned loudly. “Thank you… Master?” She’d never used the title before, but followed Rebecca’s earlier lead and tried it on. “You’re very welcome, slut. And yes… you will get pregnant.” You kept a steady pace, thrusting in and out, and images of the young Sara with the pooch of a six-months-pregnant belly danced in your head. “I can have your baby? I will grow big with your baby in me…” She rolled the thought over. She wasn’t sure if she wanted to have a baby at fifteen, but the thought of this man’s blood in her womb gave her thrills. “Yes, baby. Yes. You can have my baby.” You tightened your body, grunted and let go, spilling your cum inside her precious, fertile womb. You leaned in, gave her another soft kiss on the mouth, and then rolled off, smiling. Sara and Rebecca stayed lying on the bed, awaiting your commands.
