Garnett was 25 and lived in a small house near the local university in her town. Being close to the campus meant there was a lot of foot traffic in front of her house, especially in the mornings and afternoons. This played right into the plan she had devised for her latest game. Garnett had attended the local university a few years prior and it was there she had discovered a kink for self-bondage. Her experimentation with self bondage started out pretty mild with small things like handcuffs and tying her hands and feet. Now her games had become more daring and she was about to up the ante.
It was friday afternoon and Garnett was setting up in her garage for her riskiest set up yet. Her garage faced the street and sidewalk that during the afternoon would be very busy with the college students getting out of class right before the weekend. Recently she had set up a sybian in her garage and since she parked her car outside the garage she never opened the doors so no one could see it. Today the sybian had a new attachment, a very large dildo with a clit stimulator. The dildo was so large that Garnett was not sure she could handle the full depth inside of her, hopefully she wouldn't have to.
The plan was to stand completely naked in stirrups that she had hung down the sides of the sybian that were actually attached to a winch coming down from the ceiling. Her hands would be handcuffed behind her back to be helpless. The winch had a function to wind in or out in pre-set increments. Garnet had set the winch to lower the stirrups down slowly so that over the course of an hour she would be lowered down onto the dildo to rest completely on the sybian. Her garage door opener was also sitting underneath a pad on the sybian and set up so that once her bodyweight was fully down, it would press the button and the garage door would open and she would be exposed to all the people who regularly walked in front of her house.
Exposing herself and her kink to the world was the risk that made it so exciting but the likelihood of it happening was small because of the handcuffs she was using. The handcuffs were timed ones and she had set them to open at a random time between 45 and 65 minutes. This meant that she would most likely have her hands free to grab the rope she had above her to pull herself off the sybian and dildo before the garage door opener was pressed. This also meant there was a small chance the cuffs would leave her trapped for up to five minutes after the garage door was opened naked and riding a sex machine in full view of the public. The chance of being so exposed made Garnett's stomach fill with butterflies and she got so excited with that possibility although she knew how humiliating it would be.
For the most part the plan was already set up so standing in the garage Garnett stripped off her clothes and stood in the closed garage naked and going over her set up. The Winch was set to lower the stirrups, the garage door opener was set on the sybian and her handcuffs were set to open within the allotted time. Taking a deep breath Garnet grabbed the controls for the winch and the sybain. In the same hand she held her handcuffs, then used a stool to step over the sybian and into the stirrups that were high enough so the dildo was just touching the entrance to her pussy. Garnet took a moment to touch her body, enjoying the feeling of the thrill building inside. She rubbed a free hand over her breasts and then touched her bare pussy which she had decided to shave completely that morning.
Once her arousal was in full swing Garnet hit the start on the winch and the sybian and dropped the controls out of reach. She quickly attached her handcuffs to one wrist, then she put her hands behind her back and locked the other wrist. The click of the second cuff made her feel like she could cum from the slightest touch and she reveled in the feeling. She had done it, made herself completely helpless on a sex machine with a very large dido that would soon be impaling her. Without her hands she would not be able to lift herself off of the machine and was at mercy of the vibrations that would soon be infusing her body. She could already feel the tip of the dildo vibrating at the entrance of her most sensitive area and she couldn't believe how good she was feeling. Her time had only started and she felt on the edge of the most extreme orgasm of her life.
Just as Garnet was feeling that things could not get any better, the winch began to lower the stirrups and her with them. The head of the dildo began to press into the folds of her pussy and she could feel the vibrations much more intensely. The pleasure was increasing exponentially and a moan let loose unchecked from her mouth. With her body beginning to be penetrated by the sex toy and its strong vibrations Garnet's head fell back and she closed her eyes and reveled in the sensations being thrust upon her. Her mouth opened slightly as she was lowered even more on the dildo. Time had lost all meaning to her and she thought of nothing except the euphoria consuming her.
The only thing that brought Garnet back to a semblance of clear thinking was the sheer size of the dildo now half way inside her. She looked down to see the object now shoved so far inside of her. She was already feeling so stretched and wondered if she had bitten off more than she could chew. As the fear of taking on too much crept into her thoughts it had the side effect of increasing her arousal one step farther. The climax was unstoppable and the most intense orgasm she had ever felt wrecked its way through her body. It seemed to last forever and radiated out from her groin and all the way to her fingertips making her whole body tense and thrash.
