Stella was in full rut when I finished with the cane; one touch to her clit or nipple at that point likely would have put her over the edge. Too bad she was not going to cum for a few more hours at least.

I left her in the stocks for a bit while I readied her next ride. She had really not had any exercise for a while, so this would be good for her. After she had "cooled off", I walked her over in the corner to the tiny shower room I had there. I made her try to pee; she was reluctant to go with me in the room, but did eventually. A fast wash, with special attention to her bottom-cheeks just-in-case, with antibiotic soap. A quick rinse in tepid water to calm her excitement, and a warm-air dry. She was ready for action.

Well so was I. Ordering her into "present" position, I had her give me some head to relieve MY tension. I made a mental note to have compare methods with Sweet Mary Ellen (yah, that was her 'professional' name. She liked the schoolgirl game, and looked it, though she was 26); a few lessons would help her along. But some of ANY task is experience, and she made up for the lack with enthusiasm.

Once done, I took her to the exercise bike. And yes, it had those little modifications you read about in the porn stories. I had found the supplier for a major porn house in San Francisco and gotten the bike with the dildo which rises out of the seat, pistoning and spinning. Tom, our rigger, had gotten a local shop to make up some other interesting attachments as well as getting a few off-the-shelf at local hardware stores.

One of the modifications was a wider seat. Not every woman is 'narrow as an arrow', and that's fine! I was not, however, going to have to limit my activities due to stupid design. Tom found a seat from an old Harley Electra-Glide cop-cycle which did the trick. It also provided a nice metal bar around the back to give us another bondage point. A locally-made dohickey allowed some breast and nipple bondage.

I settled Stella on the seat and fastened the ankle straps which would keep her aboard. Wrist bonds on the handlebars were next, then the waist strap, not too tight. A little lube on the dildo and we tested for complete penetration; I loaded the reservoir for the shaft with surprise fluid. Sliding the afore-mentioned dohickey against her chest wall (where a soft leather brace prevented damage), I strapped her breasts down tight and put a couple clips on her nipples, not too severe, just to keep things fun. There were a couple wires to go to the clamps, and we were set to go!

"Stella, I like subs to get enough exercise, so you're going on a ride here, at whatever pace you choose to set for yourself. After your first two miles, the device expects you to go a bit faster, after five faster still. Faster after ten, and more so after fifteen. At twenty miles, you are done! We'll have a treat for you then. You have a Gatorade nipple next to your head, and I want you to stay hydrated so drink every ten minutes or so. You WILL have access to the gear-shift so the pedaling won't be anything extreme for you, and the machine is set, today, to have your course all on the flat."

"Now for the fun parts. In the first five miles, you get the dildo pistoning every 10 turns of the wheel, and as you go further, it happens more often. You may *try* to cum, if you can, as often as you wish. Be ready, though, for an occasional concern with that effort. I'll be sitting right here watching and taking care of the business while you ride. Have fun!" I patted her on the shoulder, and gave her a quick, deep kiss.
