I had a first-time experience yesterday
I was watching a poppers training video, one I had seen before, more or less casually. I wasn't following all of the instructions for toys, etc., and initially even I hadn't gotten out a bottle to sniff. Part way in, though, I did retrieve a mostly used up bottle and took a few hits. Very shortly after that I started feeling an urge to cum building up. I've experienced something like that in the past, usually when I'm just teasing my cock a little bit. Usually if that happens I wind up going ahead and stroking off to an ejaculation. This time I didn't do that, but suddenly from a mostly limp cock I felt myself cum, hands free. I resisted the urge to add some stroking and let it just play out. Afterwards I was so horny (still) that I did get myself hard and bring myself to another small ejaculation. I've never had a hands free like that nor have I ever cum twice in the space of about 10 minutes like that. I don't know what role the poppers played in it, as I wasn't even all that gone from sniffing, but I can't help but think that I'm beginning to get so programmed from all of the videos, popper training and others, that my body just responds on its own. Does anyone else ever experience hands free from sniffing?
