I (F19) let one of my fwb’s (M48) tie me up in a fucking machine and they left me for hours
I have a dominant-bottom fwb with one of my teachers and we occasionally do cnc (it's not my favourite but part of the kink of the age gap for me is being used and he really wants it. He's earned my trust after knowing him over a year otherwise I wouldnt). A few days ago during a cnc session he told me his friends would be watching, then started putting me in some complex bondage more extreme than I've done before.
I was tied up over two thick planks of wood nailed together, in an upside down T shape, with the part sticking up shorter than the length of it. I was tied up so that the wood was jutting into my gut and I couldnt get a full breath. My hair was tied to something I didn't end up seeing on my way in or out but it was kept taut so I had to keep my head raised with my own strength and couldn't rest it. A massive butt plug was put in me that vibrated and binder clips were put on my nipples. Finally they gagged me and tied an intense vibrator on my clit, and inserted a massive dildo part of a fucking machine into me and turned it and the vibrator on.
I almost immediately couldn't think straight, it was so intense and humiliating. They literally just started playing a couple rounds of video games while I got my brains fucked out in front of them to the side. That didnt last for long though because only about a half hour in one of them took a phone call and went to the other room. When he came back he spoke to the group and they then told me they had to go do something and would be right back, about 10 minutes or so. They were completely casual and dismissive of the fact I was still in bondage and on my second or third orgasm already.
Well, they weren't back in ten minutes, or twenty. It took about another whole half hour for anyone to show up and it was just one of them. He didn't say a word, just added more lube to my sore pussy and left again. I was alone for about an hour again until someone came and added more lube, and removed the clips. Then left again. One more hour later and this happened again, and then another hour later they finally came back and let me out.
I basically passed out after. I couldnt stand or support my own weight on all fours so I just laid there when they untied me. Eventually one of them got me a blanket and some water and I fell asleep, and when I woke up the rest of them were gone and it was time for me to go home.
That was one of the most intense experiences of my entire life. I honestly wondered if I was going to be there all day
