I had known Ruth for several years in fact we had dated for a short while. She was a very petite part Filipino girl with long dark hair and small proud breasts. I was working as a paramedic and had lost track of her for a while and was surprised to see her at the pain clinic as we dropped off a patient. We chatted for a while and she ask if my back still bothered me. I had been having problems off and on from lifting the stretcher. I told her from time to time and she said I should come see her some time and she would fix it for me. She handed me a card which I put in my pocket and did not look at.

We finished our tour and I happened to remember the card she had given me and decided to look at it. She had written on the back that she was working alone and late on Friday evening if I wanted to stop by.

I had fond memories of our times together and thought it would be an interesting time. I showed up at the clinic at about 8pm as she had instructed and watched as she ushered the last patient out and locked the doors. She motioned for me to follow her to the back and soon had the doors all locked and sat down at a desk. We chatted for some time about the past and what was going on and then she asked if I wanted her to work on me. I had no problem with that and quickly got undressed as she moved about the room getting equipment.

She did not bother giving me a gown or sheet I guess since she had seen me nude before. She pulled on some gloves and told me to roll on my left side and soon I felt her hands on my ass followed by something cold sliding inside me. I asked what she was doing and was told taking my temp. She moved the thermometer around a lot causing me to squeeze my ass muscles tight and try to concentrate on my cock not getting rock hard which was a lost cause. She removed the thermometer and then told me to stay there and soon rolled an iv stand with a large enema set up on it. I did not complain as she slid the tube in my ass and then inflated the balloon nozzle to hold it in place. I soon felt the solution start to flow and she moved around to the front and ran her hands over my abdomen to help with the cramps. She then slid her other hand over my cock and balls which really helped with the cramps. She finally disconnected the tube but left the nozzle inflated in my ass holding the solution inside me. She then helped me to roll over on to my back and ran her hands up my chest to play with the studs I had in my nipples. I always did like these she commented.

She then proceeded to move my arms and legs around and then soon had them in leather restraints. I did not complain since we had played this way when we were lovers. She walked over to the cabinet and returned with several needles and I soon felt a cold alcohol swab rubbed across each nipple area. She soon took the first of the needles and uncapped it and then using the other hand pulled my nipple up and slid the needle underneath the piercing stud. I groaned with the pain as she smiled and told me there were more to come. I groaned with each insertion but my cock was rock hard. She finally inserted the last one and then took some electrode clamps and attached them to each of the piercing studs. She moved to a machine and turned some dials and I soon felt the current moving thru the studs causing me to arch off the table and groan with the pleasure. She kept increasing the current and I was soon almost yelling from the sensations as she reached over and used her hand on my cock causing me to shoot a large dose of cum on to my inflated stomach. She reached over and turned the machine off as I lay there trying to regain control of my breathing. She soon had the enema tube out and placed a bed pan for me to use to expel the solution.

I finally was able to regain control of my senses and was rewarded with watching her slip out of her uniform and then her small white bra and matching thong. She then walked over and picked up another device and lubricated it up and moved me around until she could slip it deep in my ass. I groaned from the cold stretching device but lay waiting for the next bit of excitement. She then returned with more needles and this time moved down to massage my balls and soon began to insert the needles in to my ball sack. This was a lot more painful than the others had been but she soon had completed her work and then hooked some more wires to the device in my ass. I soon felt current flowing thru my nipples and then deep in my ass and over my prostate. I was shaking my head and moaning from the sensations as she stroked my cock and then stepped over me and slid down on to my cock as the sensations moved thru my body. I felt her hot tight wetness envelope me and was soon filling her with my cum as she matched my motions until she also reached an orgasm.

We both lay there exhausted from the experience for a while and then I groaned as she slid off me to the machines which were still pulsing in my ass and nipples. I soon felt my spirit come back to life as the sensations increased and turned to watch as she attached electrodes to her nipples and then slipped a large one inside her wet pussy. She also lubricated her ass and moved back over me pulling the machine closer so she could adjust the controls. She was soon moving to the pulsing currant in her pussy and nipples and my cock was standing at attention again. She climbed up over me and this time slowly inserted my cock in her tight ass. I tried to move up deeper but she told me to lay very still and she would do all the work. She reached over and moved the controls increasing the flow of current for both of us and soon she was bouncing on my cock taking it deep in her ass as the current pulsed thru my nipples and ass and thru her nipples and pussy. We were both soon yelling loudly as orgasm after orgasm swept over us. Finally at the point of exhaustion she reached over and flipped the machine off. She lay across my chest and smiled and asked if my back still hurt. I told her it was fine but I know it will start to bother me again real soon.....
