I called the older sub that had participated at the party and told her to meet me at the club a 6:30.
I instructed her to cleanse herself, figuring she knew what this meant. We were alone which was rare, but allowed me the use of any equipment available. The first order of business was to check to see if she followed my instructions. After she was shed of clothing, I motioned for her to climb onto the table and place her feet in the stirrups. As she did this, I noticed she was already aroused. Her labia were swollen and moisture evident. I wondered if it was the stirrups that triggered this or the prep, which consisted of multiple enemas. I figured it was both.
With her feet strapped into the rests, I pulled her torso down and adjusted the stirrups so her knees were pulled back and her legs spread as far as possible exposing her entire lower region.
I took a cotton swab, coated it with alcohol, a proceeded to clean her inner labia. She quivered thinking I was going to pierce her lips, but that wasn't the case. I wanted them dry and void of her moisture. With that accomplished, I placed a clamp on one lip and tightened hard enough to insure it wouldn't come off. I pulled it all the way to the side and taped it in place. I repeated the action on the other lip and when I was finished all of her orifices were exposed and available, all three of them.
With the preliminaries out of the way, it was time to check her colon to see if she had followed my instructions. I took out my specially designed rod for anal inspection. It wasn't anything exotic, merely a rod I had made that was 10 inches long, slightly tapered, about the size of a quarter at the largest diameter, and had small grooves along the length to collect any waste present. She had never experienced this, so it would be an adventure for both of us.
I made a production of coating the device with lube, which I knew she enjoyed watching in anticipation of the penetration to come. When it was coated, I squeezed a fair amount on her anus, and then began working the paste into her sphincter and inner bowel. We both enjoyed this exercise, the penetration of my fingers to introduce the lube as well as explore the inner walls of the passage.
She was aroused and loose, pushing out to assist me in my task. I took the rod and placed the tip on the orifice. With gentle pressure I coaxed it through the sphincter. The first inch went easily in and then some resistance was felt. I moved it about, changing the angle so that it was pointed more towards her stomach, and found the opening. Now it was unobstructed. Groove by groove disappeared through wrinkled opening, each one making her squirm a little more. I could imagine the feeling as the rod went deeper and deeper into her.
Her other orifice was responding as well, muscles clenching with each groove entering. When she relaxed between the penetrations, her vagina was wide open in arousal, a portion of the inner wall visible. That disappeared quickly when the penetration caused another involuntary contraction.
