Third Class
She walked into the classroom to find no desks, chairs or mats. Instead girls seemed to be strapping themselves onto the walls. There were panels with four cuffs that left you spread eagled vertically against the walls. There were platforms for your feet to stand on but your ankles and wrists would be held down. Lauren found a free panel and undressed before locking herself in. Soon all the panels were filled with horny girls waiting for instruction. Then in walked Ms. Screw, a gorgeous African American woman with voluptuous tits, at least a DD cup and a gorgeous curvy figure. Her lips were painted red and she had on black eyeliner that really brought out her dark brown eyes. She was wearing a tight tank top that her breasts spilled out of and a blazer over top of it. On her bottom half she wore a pencil skirt to match the blazer that reached only to her middle thigh. Her legs looked long and sexy in her shiny black heels and stockings. “Good afternoon ladies” she said looking at them and checking their bondage. “Today we will be using the machines that you are currently hooked up to, to test your stamina. You will be pleasured by the machine and brought just to the edge of orgasm over and over, and you may feel over stimulated and sensitive but the machine is monitoring you and won't let you cum. You may only cum if you can convince me through begging, however I am not easily persuaded. Good luck ladies!” she said with a smirk on her face. Lauren felt a blindfold get wrapped around her head. Her other senses were more alert without her sight and she could hear the machine shifting and felt silicone hands massage her shoulders, neck and stomach. They moved slowly down her body, avoiding her breasts and pussy but gently rubbing her inner thighs. She let out a soft moan and enjoyed the massage. Soon the machine started gently fondling her breasts and around her hard nipples. She let out a whimper and a loud moan when she felt small suction cups latch onto her nipples giving the same effect as if someone was sucking them. She writhed around on the panel, as the pleasure was overwhelming. Then she felt a small silicone piece flick at her clit like a tongue. She screamed again and bucked her hips into the air. Soon another suction cup was added to her clit and she was dizzy with pleasure. Suddenly a smooth 8” dildo pushed it's way into her pussy and she almost came all over it leaving a puddle below her. The dildo went in and out slowly, working her up again and then suddenly slammed into her filling her up completely and she almost came again. The machine was just warming up though, it tickled her nipples and squeezed them lightly as she continued to squirm around trying to find release. Her orgasm built up again as the clit suction cup started to vibrate but it all stopped as right before she got that sweet release that she was so craving. The room was filled with girls whining and moaning all wanting the same thing. The machine worked her up over and over and she had edged about twenty times before she started to beg. “Ms. Screw!” Lauren called out panting from the sexual torture. Ms. Screw took her time walking over and looked her up and down before responding to the frustrated girl. “Yes my dear?” Ms. Screw asked her, with a smile playing on her lips. She couldn't wait to hear this pretty one beg. “Please let me cum miss! I don't think I can take it anymore! It hurts it feels to good! I need to let go, please!” She begged, moaning in between sentences. “Oh darling, I think you can last a little longer. Only sluts beg to cum like that.” Ms. Screw told Lauren, as she smirked and started to move on to the next girl. “No please dont go! I am a slut! I'm a little whore who needs to cum for you miss!” She yelled. This caught Ms. Screws attention. “Oh do you? Well then tell me more.” She insisted. Ms. Screw always loved it when she got a girl willing to humiliate herself for an orgasm. “I'm such a slut Ms. Screw! I would do anything to cum. I love it so much! I need orgasms like I need food and water, and it feels so good, I might pass out!” She rambled on, not really able to think about what she was saying anymore. “Fine, you may cum. The machine will shut off by itself when your done. Don't expect this to happen again. I don't let my students cum very often.” She said and the walked off to her next moaning student. Lauren felt every part if the machine turn on as the dildo slammed into her hard and fast and the suction cups vibrated on her clit and tits. She let out a scream as her body tensed and pleasure flowed through her for the third time thay day. She collapsed in the restraints and took a moment to catch her breath. The machine folded its self back into the wall and undid the cuffs holding herself upright. She took a wobbly step down and put her outfit back on. Finally it was time for lunch.
