I am one of those people for whom normal s** just does not give me the rush I need. I need far more intense sensation. Of my many options and practices, needles to the balls is perhaps the ultimate high. Do not do it often but ehen I do it is not a quick casual thing. Wife does not approve or partake/assist so I have to be stocked and have the supplies at office (needles and medical gloves/hygiene supplies, just because I relish doing this to myself does not mean I am ignotant of the risks). So one weekend morning I had just gotten started behind closed office door, one horizontally through each, and about to start the first vertical one from the bottom, and my door opens as a female co worker walks in and I am sitting naked from the waist down in my chair with my legs wide, feet on desk, with a testicle in fingers of one hand and the next needle in the other. So imagine the stunned face I am seeing looking at me. Pure silence before I manage to say “Sorry to appear exhibitionistic but I cannot move too rapidly at the moment, I am not trying to flash you.” In my head of course I am thinking about how I will need to find a new job. And hoping she does not manage to whip out her phone to take pics as proof as I slowly swing my feet down to the floor. But instead of storming out she closed the door and sat in the extra chair in my office and looks at me silently. After a moment she says to go ahead. I was stunned but realized she was perhaps drawn to the fucked up macabre freak showness of it. I took a breath and proceeded to skewer my right testicle from the bottom up as I had been about to. Head dizzy and gasping as I rode out the sensations. She did not take her eyes off my balls. Since this is not s***** for me my quite tiny p**** was completely limp but was dripping by now. From her all I got was “now the other one.” Now it was intriguing. She approached and knelt in front of me only to watch. I gave her a clear close view of skewering the left and eas in my endorphin high. As that crested and began to wane, she actually thanked me because she had always wanted to see something like this but her boyfriend was very conventional. I could not quite believe myself when I asked if she wanted to do more than see it, and she looked at me wide eyed. I told her to use the hand sanitizer then glove up. Talked her through opening the single use needle pack and held a testicle still for her. She hesitated and I gently took her hand and said “short sharp push to start, you will feel a lot of initial resistance” then gently pulled her hand towards me. I winced at the initial jab but then it was entering the testicle and I stopped her. Breathed several times and told her slow steady push all the way in. She was fascinated by watching it sinkbin fully. And it was so much better not having to do it myself. I was moaning and in heaven. She let me breath through it again and then I asked her to do another on the other side. She took to steadying the testicle well perhaps detachedly. When she asked how many I use I told her these two with her help were records. She smiled at that. I pushed my luck and asked if she would do each side top to bottom and her eyes lit up. As the endorphins faded I asked if she minded removing them. She did so so slowly, each side in turn and soooo slowly. By the end it was also a record for blood trickling out and the fun was over and the usual slightly nauseous feeling set in. But when the last one was out she asked if that was enough for one day, and I nodded and reached for the alcohol wipes and rolled gauze and pads, but she actually stopped me and told me to let her do it. There was nothing arousing in it but it was comforting as I got my head back on straight. Hell once she had cleaned me up and gently gauze wrapped me she helped me to unsteady feet and helped get my pants back on. She asked if I was ok and I laughed and said i simply needed a cigarette. She lit it for me and put it in my mouth and then lit one for herself. We chatted about work. She asked how often I did this and I told her only a few times a year. And definitely not again for a few weeks simply because of the number. She said “no s** ever but can I help again next time?”. I told her thanks to the ability to enjoy the sensations without having to do it myself, she was very welcome to. As she finished her cig she stood to leave and said “so again no s** but I have always wanted my t*** to be pincushioned with needles.” I told her any time.
