Oh and since I'm in a sharing mood here's the story of my longest period of chastity. I had a friend who was very into chastity, and I had experimented with short term orgasm denial and was curious about something more serious. One day we happened to be talking about it and I asked if he would like to be my keyholder and we ended up in a dynamic for about 6 months. I was never fully locked up (see previous comments) and got to orgasm about once a week, though I did eventually get denied for a little over a month, so sorry to anyone hoping for a more "hardcore" story haha.
Equipment: As I mentioned above I wore a groin protector most of the time which covered my clit and pelvic area, which is an erogenous zone for me. Originally I wore nothing but we found my hands wandered far too much, while having the groin protector on just felt different on a visceral level. Technically I could remove it (and I did remove it to shower) but wearing it felt right and made me much more obedient. It was pretty easy to hide under most clothes, but if I couldn't wear it I had a little plastic shield I could tuck between my labia to prevent any accidental rubbing on my clit, which made me feel very snug and secure. Later on my keyholder also started ordering me to wear silicone nipple pasties 24/7 and from then on the only pleasurable stimulation I could get was from the constant throbbing in my clit which could be very intense at times.
Routines: We would meet up once a week and he would generally bring me to orgasm during these sessions, provided I had been good during the week and kept my hands to myself. I loved the ritual of being "unlocked" and cleaned. Although I did remove the shield to shower, I was expected not to directly touch anything underneath and just kind of let water run over the area until I was satisfied that it was clean. When my keyholder visited I would undress and stand in the shower with my hands on the wall while he removed my shield and soaped me up between my legs, methodically running his fingers in between my labial folds and retracting my clitoral hood to clean my clit. He liked to push a finger into my vaginal canal to "make sure I was clean" and then dry me with a towel, all while I was still standing with my hands on the wall. Then he'd bring me to the lounge or bedroom and do whatever horrible thing he'd planned, and hopefully I'd be allowed to orgasm at the end. My favorite was being laid across his lap while he alternated between spanking and fingering me. I never cared much for spanking before but that felt amazing, and being wiped down and re-locked afterward felt amazing too. Unfortunately if I had been bad or he was in a devious mood he would just edge me, let me cool down and put the shield back on and I knew it would be another week before I had another chance to orgasm.
Submission: Obviously I have a submissive streak but believe it or not my natural inclination is mostly dom leaning. However, being in chastity made me INTENSELY submissive like nothing else ever has. I'm not a particularly good sub most of the time, I usually feel like I'm just larping. In chastity I loved feeling controlled, I loved being called a good girl, I wanted nothing more than to please. Really strange experience for me but not at all unwelcome.
That time I didn't cum for a month: Toward the end of our time together my keyholder expressed interest in denying me for a longer period. Each week he would still tease me but really dialed back the intensity, e.g. instead of the rougher bdsm stuff/edging we would normally do, one week he spread me open and lightly stroked my clit with a lubed up q tip for half an hour, another week he used a suction pump on my clit and nipples on the lowest setting, another week he oiled me up and used rubber exfoliators on my whole body. I don't know why but it sent me absolutely wild. Physically it wasn't particularly arousing, mentally it made me feel so so helpless and submissive. A couple of times I nearly cried because I truly felt like I was just someone else's plaything. During the week I didn't feel acutely horny so much as utterly controlled, though my clit did still throb constantly and my groin shield and nipple pasties were constant physical reminders of my denial. This went on for about 6 weeks and I consider it my "true" chastity experience because I was in such a different place mentally.
Unfortunately around this time there were changes in other areas of my personal life that meant I could no longer fully focus on our rituals and dynamic. My keyholder also got a job opportunity that entailed a lot of long hours and time spent out of town so we decided to call it off. During our last session together I had my first orgasm in 6 weeks and predictably, it was one of the strongest I've ever experienced, but what caught me off guard was how *long* it went on for. It felt like I came for a solid minute and he continued to stimulate me mercilessly for another minute afterward, which left me suitably shattered. These days I'm the dominant partner to a very submissive slut. My old keyholder and I are still in touch and technically the door is open to resuming some of our old dynamic but realistically I don't think either of us have the bandwidth or headspace required for that, nor will we, so this is just a happy memory and a very special experience.
