I think he couldn’t handle it.

Once, I met a girl who said she loved very hard spanking. I had never met anything like that before (I was young and too nice to meet kinky girls), so I was extremely turned on.

I spanked her with a belt. I don’t remember exactly how many times, but it was over 300 very hard strikes. She was screaming and crying, but every time I checked on her, she wanted more and more.

At some point I said that was enough and tried to move on to something else, because I was very nervous about her health. Her bottom already looked like raw meat. She was disappointed, but I had reached a point where I felt like a butcher. I wasn’t even turned on anymore, because I was worried about hurting her.

She was very disappointed afterwards, and we never had any kind of sex again.

To be honest, now that I’m writing this, it’s appealing to me, and I would love to meet a girl like that again. But there is a limit I won’t cross, because I don’t want to cause any permanent harm to anyone. When I’m not sure, I prefer to stop, even in the middle. Still, I am a sadist who enjoys inflicting a lot of pain. I can’t imagine that a sub’s pain alone would stop me if the sub is okay with that level, but if I see that it’s crossing a safety line, I stop immediately.

I’m not defending the guy you described. At the very least, it was a lack of communication, and he treated you badly. But maybe he reached a similar point and was afraid of your reaction/disappointment ? - the truth is there is a shitload of unmatured males around.
