My partner K has fallen into the hobby of making DIY sex items for us lately. He has a 3D printer that he has been putting to good use. If I’m honest I also think he is enjoying giving me material to write about and post for you all. As a reminder, I am 27F, 5”3, curvy build with large breasts and working on the ass, long straight brown hair that goes past my waist and green eyes. K is 30, 5”11, built like a trades man, short brown hair and a short beard and amazingly blue eyes. Please leave feedback and check out my other stories!

I was having a long day at work, finding myself nodding off, so I had texted K asking him to distract me. He sent me a link to a reddit post of a forced orgasm chair. This entire concept was new to me but essentially a vibrator is on/in the seat and there is a mechanism to tie the user up to the chair so they are unable to move. He told me he had been working on making one for us. Needless to say, that woke me up a bit and had me feeling hot while working.

Later that week, I came home after a super busy day with plans to just craw into bed…K had other ideas. Upon entering my room I saw the completed chair, my eyes widened in apprehension and excitement. I cant say I understood the mechanisms, but the vibrator was strapped to a chair with rope. K wasted no time in stripping me of my clothes and sitting me on the chair.  The cool air of the room hit my skin sending a shiver up my spine and giving me goosebumps. Despite the lack of warm up time I felt warmth quickly spread between my legs that was sharply contrasted by the cold head of the vibrator hitting me in just the right spot when I sat down. K worked quickly to strap my legs to the chair. The way he had me positioned had my legs spread apart enough to expose my clit directly to the vibrator. K then took handcuffs, wove them through the back of the chair and handcuffed my wrists behind my back. I experimented with movement and found if I planted my feet and tried to stand up I could relieve a small amount of pressure from my clit but it would still be touching. I could tilt my hips forward and back a bit as well but beyond that I couldn’t really move. Next, I was blindfolded. With my vision gone the rest of my senses were suddenly heightened. My skin felt like it was crackling with electricity.

Without saying a word, K turned on the vibrator to a low grumbling setting. I gasped at the stimulation and felt myself become wet. K’s hands reached for my breasts, and he played and groped them in a way that felt as though it was purely for his enjoyment. Being used in that way is such a turn on for me. As he twisted and pulled at my nipples my breath increased in rate and I pushed my hips into the vibrator. The vibration felt so good against my swollen clit, but it was not quite enough. I felt a growing need deep in my belly.

Suddenly, a sharp pain shot across a nipple and I realized K was putting nipple clamps on me. The pain was delicious and as he tightened the clamps an involuntary moan escaped my lips. He gently pulled at the clamps, eliciting gasps from me. He chuckled at my mix of pain and pleasure which was a truly delicious sound. The vibrator then increased in speed and intensity, apparently K had turned it up. This was the setting I tend to use on myself; pleasure shot through me in waves. I started to pant and groan as I felt an orgasm build up inside me. I adjusted my hips the best I could to hit that sweet spot and suddenly I was cumming fast and hard. I laughed at the sudden pleasure but when the waves passed and I couldn’t relieve the stimulation from my clit I realized what I was really in for. I was hypersensitive and the vibrator was unrelenting. I planted my feet on the ground in an effort to relieve some pressure and groaned at the mix of pleasure and pain. My back was arched with my head cocked back allowing K to grab a handful of hair at the nape of my neck and kiss me hard. I heard the unbuckling of his belt and as he released my hair I bent forward as much as I could, the handcuffs digging into my wrists as I sought to get his cock in my mouth. He gave me the luxury of allowing the head of his rock hard cock touch my tongue for a few seconds before he withdrew and stated, “okay, I’ll be back later”. I gasped in shock as I heard the door to bedroom open and close. Was he really leaving me there? How long would I be strapped to this chair and how was I going to cope? In truth, I don’t know if he left or if or if he silently stayed in the room and watched as I writhed and squirmed on the chair, naked and tied up. Either is so so hot.

Soon, the overstimulation turned into pleasure again and another orgasm built within me. I could hardly contain my moans and was worried others in the house would hear. The next orgasm slammed into me hard, almost painfully and I rode it out as best I could. My legs were jello as I tried to relieve pressure from my sensitive clit. I was dripping at this point, my head was thrown back, chest heaved and tired moans escaping my lips. Sometime later time K was back, calling me “good girl” and “slut”. I threw away my pride and through heavy breaths told him I couldn’t cum anymore. He just chuckled. I whimpered and repeated that I couldn’t take it anymore. Rather than release me from the delicious torture K told me that he’d set a timer and that I better cum again before it goes off…’or else’. My legs were shaking, I was covered in a sheen of sweat and my brain was mush. I truly did not think I could cum again. I was so tired that my moans had quieted, and I was just breathing heavily. My pussy was throbbing, hot and soaked. Just when I thought I’d have to tap out a violent orgasm ripped through me with little to no warning. I called out loudly and in response K immediately turned off the vibrator. He helped to support my weight and worked to release me from my restraints. He took of the blindfold and kissed my face gently as I adjusted to the light. The dominant man turned back into my gentle, loving partner as I recovered. He helped me move to the bed and allowed me some time to recover. I could feel my wetness running down my leg. I was honestly shocked at how turned on I was.

After only a few minutes K was ready to fuck. I was so spent I was ready to just let him take me however he needed. He, however, wanted me to ride him. My legs were still shaking, and I honestly did not think I’d be able to manage. K didn’t care though; he spanked my ass to show me he was serious. I did as I was told, mounted K and slid down onto his hard cock. Despite my exhaustion having him buried deep inside me felt so good I was reenergized. I bounced up and down, relishing the way his length filled me up. K played with my tits as I rode him like my life depended on it. He looked at my body with so much lust in his eyes and he began to breathe more heavily. This was about his pleasure now. He started bucking his hips to meet mine as I rode him and we found a delicious, impossibly fast rhythm. Soon K’s breath hitched in the way I know so well, and he came deep and hard into my pussy. Each twitch of his cock sent a wave of pleasure through me. We lay like that for a while until our breaths slowed. Then we cleaned up and fell into bed, falling asleep instantly.

That chair was one of his best contraptions yet and I have to say I’ve sat in it by myself as well 😉
