Chapter 1 - awakening

Her eyes open, blinking rapidly trying to clear the sleep and confusion from her head while she tries to make sense of her surroundings. She tries to move, but finds herself restrained, her wrists bound together above her head.

She begins to panic, realizing that her slim toned body is naked, that her mouth is filled with a gag, and her legs are spread wide by a saddle type arrangement. Most horrifying to her is that her sex is impaled on what feels like a large dildo. She struggles, rapidly realizing the futility of her movement as her thighs remain bound to the saddle and the dildo remains in place.

Experimenting, she manages to raise herself a few inches, the ribs of the cock embedded in her causing the folds of her vulva to ripple as it emerges from her body. Relaxing back down, she is surprised by a whirring sound, and as she takes the dildo back inside her it begins to vibrate, slowly at first, and more rapidly as she lowers herself back into the saddle.

The vibrations reach their peak as she settles her engorged lips onto the seat, her intimate lips spread around the base of the cock. As she pushes down, her body subconsciously responding to the vibrations, the sweet sensation comes to a halt, even as she grinds her pussy into the flared base of the dildo. At that moment she feels a squirt, and a rush of sweet, warm liquid into her mouth. She gags in surprise, panicking as she tries to expel the fluid, before she calms as she realizes it does not taste bad, and swallows it.

A voice sounds, and she looks around her at a small, plain room, not seeing any obvious source.

"Relax. You are in no danger. You do need to understand your predicament however. The saddle you are riding is a Sybian. A powerful vibrating core with a dildo attachment that you will remain impaled on. Pushing down with your pelvis so that you vulva a clit press on the platform will cause it to vibrate for 30 seconds. Each time that happens, a shot of high calorie syrup and butter mix will be pumped into your mouth using the gag. You will have to swallow it. Periodically the shot will contain a sleeping drug, sometimes a powerful aphrodisiac. If you're able to control your sexual urges, you will be able to gain a nutritious diet, but if your libido gets the better of you you will rapidly ingest tens thousands of calories. Good luck. You're going to be here a while."

She struggles again, suddenly realizing the nature of her predicament, and in the course of her thrashing, activates the vibrations. Moaning, she presses down with her hips, grinding against the saddle until the sweet ministrations stop and she is rewarded with another jet of sweet buttery syrup in her mouth...
