I helped her off the table since the ordeal seemed to drain her. I positioned the chair so she could observe what I was going to do to the first volunteer. I sat her down and kissed her, gently squeezing the bruise marked breasts. She shuddered and slumped into the chair, content from the orgasm and obviously still feeling the ache of the zippering.
I helped the plugged and evacuated lady up onto the table. I had her lay on her back with feet pulled back and knees spread. I scooted her towards me so that her head hung down off the edge of the table. I had one of the onlookers find a wastebasket and bring it to me. While that was being done, I took out the instruments for the next scene. When the woman returned with a wastebasket, I placed it on the floor under her head, just in case it was needed.
She looked lovely, head bent back, throat exposed and in position. I stroked her throat lovingly, running my fingers along the length of it. I think some in the crowd had an idea what was going to happen, but I knew they had no inkling of how it was going to be executed. The scene materialized as I took off my pants and shorts. With her head bent back and throat aligned, it was a natural.
Before I started, I needed two more items from the valise. Gasps emitted from some of the audience when they saw what was being retrieved. The sterile packages were self-explanatory. I solicited two volunteers to hold her arms down alongside the table legs, it was extremely important that her upper torso remain immobile.
I moved into position and placed my cock on her lips, which immediately opened to allow entrance. I pushed in part way and let her work on the head, sucking and covering it with her saliva. Her tongue was working wonders, my cock was already hard but was already erect, but she was making it rock hard. This went on for some time and then I couldn't wait.
I tore open one of the packages, took out the 20-gauge needle normally used for large injections. I pushed to the back of her mouth, and then holding her left nipple with my left thumb and forefinger, I placed the needle on the side of her nipple with my right thumb and forefinger. She winched a little when she felt the sharp tip, but didn't protest.
With steady pressure I pushed the needle through her nipple. She opened her mouth wide to scream but I took the opportunity of an open throat to push my cock all the way in until my balls were against her nose. The pain in her nipple overrode any gag reflex, I doubt if she even knew what was happening. Her muscle reflexes in her legs lifted her hips straight up however.
Gradually she came back from her pain-induced semi-coma. Now she was starting to gag on my cock in her throat. I pulled out to allow her to breath. She turned her head and spit out the accumulation of saliva in her mouth, but was in control and didn't vomit which was what I was concerned about.
