Ann stared at the machine that she had spent the last two years creating. At 37 she did not consider herself beautiful, but rather plain. She was 5' 7" and weighed in at 127 lbs. light brown hair to the middle of her back.
She stood there with her half empty glass of red wine in her hand and the half empty bottle on the small table. Her hand shook slightly as she thought again about what she was about to do.
Taking another long drink of the wine she stepped to the keyboard on the bench. With several key strokes she set everything in motion. Now all she had to do was straddle the machine and settle herself into position. Kicking off her flip flops she let the light summer dress slide over her shoulders and puddle around her feet. She was naked as she never wore any underwear under her clothes when she was at home.
The inside of her thighs were wet as she put her knee on the padded leg support and swung her other leg over to rest on the support on the other side. The body of the machine was well padded where it supported her pelvis and chest. She had tried her best to think on everything for comfort. Her clit rested on the rubber nubs she had mounted there. One tit on each side where it narrowed down. Now on her knees and resting on her elbows she waited. She panicked again when she heard the machine come to life. She had done this twice before and she had made it back off the machine before the cuff mechanisms could close on her. But this time the wine had slowed her reaction time down as she had hoped it would.
She had built a fail safe mode into the machine. Once the abort command was typed into the keyboard. The machine would not reboot for 48 hours.
She worked 5 days a week with a lot of overtime as a robotic technician. Which gave her the knowledge and the access to the material to build the machine she was now restrained on. She would lay awake at night and think on the design and the materials she would need. Sneaking pieces out in inconspicuous places in her mini van she managed to get everything out without getting caught.
Two years and she had finally finished the machine 3 weeks ago. Two panic attacks and two aborts. And two lost weekends. She had thought of the wine last night. And it worked. Now, Saturday afternoon, in the basement of her small country home she was going to experience what she had for so long fantasized about.
The monitors she had mounted on the wall lit up. The computer was recording everything. Nothing would be missed. On the monitor on the right she saw her ass. The monitor in the middle she saw her face. And the monitor on the left she saw the tank and machine. Oh God, the mixture in that talk. She had mixed that one manually. She had been pissed at herself for chickening out the first two times. She had wanted to punish herself for it. Now she looked at the red liquid in the tank. Nine ounces of glycerin, six ounces of peppermint castile soap and a large bottle of the hottest hot sauce she could find with enough water added to bring it to three quarts.
The machine lurched and started rotating. Lowering her head towards the floor. Wrapping her hands around the grips she had been smart enough to put on she waited for the machine to stop..The machine stopped. Her head several inches lower than her ass but nothing too bad. She could only hear herself breathing. The basement quiet. Several seconds passed and nothing. She was beginning to think something had gone wrong. Then she heard a slight click and a quiet whirring sound.
She looked up at the monitors. In the right monitor she could see the rubber blades closing in on her ass. Then she felt them slide into her crack. A slight pause. Then she felt her cheeks being pulled apart. The blades stopped and she could see her little rosebud slightly opening and closing involuntarily.
She moved her hips and felt her clit move over one of the rubber nubs. She closed her eyes and continued to jerk her hips. Waves of pleasure shot up through her core. She could feel her climax growing. Her hips were moving faster when she heard the slight click. Opening her eyes she stared at the monitor. There was now a small red dot in the middle of her anus.
The laser sight. Knowing what the red dot meant, panic set in once again. She tried pulling her hands back through the steel cuffs that were locked around her wrists. It was useless. She tried moving her ass from side to side but the red dot stayed centered on her anus. Then she heard the whirring sound and saw the image on the nozzle move onto the screen.
How many hours had she spent designing and building that nozzle? How many times had she brought herself to orgasm thinking about that nozzle being pushed into her ass? She had made it out of a sturdy plastic. The hole in the center the size of a pencil. Two inches back from the round tip was the white rubber retention balloons. Whose composition made them virtually indestructible. They could be inflated to an incredible size and not rupture. But four pounds of air pressure Inflated it to the size of a large orange and that was where she had set the nozzle when she had tried the first time.
She watched and felt at the same time the nozzle make contact with her ass hole. Steady but powerful pressure slowly pushed the nozzle in. She watch and felt her hole being forced open. Then the sharp pain as her ass was forced open large enough to take the balloon. She watch the balloon disappear into her ass. She breathed easier now. The machine had stopped pushing.
She jerked her hips again driving her clit down hard onto the nubs. It was in her. Her beautiful nozzle finally deep in her ass. Frantically trying to reach her climax she didn't hear the light click or hear the hiss of air. Suddenly she felt the nozzle expanding inside her ass. Quickly getting larger. The balloon between her cheeks also expanding. It forced her over the edge. Her climax starting deep inside her. She lost control of her bladder. Piss sprayed from her and she couldn't stop it. Listening to it splatter on the floor she jerked a few more times. She had never cum so hard in her life. Tears rolled down her cheeks as she sobbed in release.
