I was chatting with a guy about pain during sex, and I realised what was so hot about face slaps. It's not the pain itself, but the surprise and unfairness. Let me explain.

The first time I was slapped happened when I was a 3rd year student in college. I was dating a guy with a sadistic streak. His name was Jan.

I remember this vividly.

I'm on my knees focused on pleasing him. I am in a world of my own, ignoring everything else around me. The only thing that matters to me is the cock in front of me.

I'm rhythmically taking is cock inside me: up and down, up and down. This steady rhythm becomes whole existence.

Suddenly, he pulls my head back by my hair, and immediately - a sharp SLAP jolts me back into reality. I look up and see his hand still hovering in the air. He grins at me as I blink back in shock. My cheek burns. I can even lose lose my balance. That slap was a violation of everything I thought was going to happen. It was unexpected and unfair. I tried so hard!!!

The surprise and unfairness are a turn-on because they show that you have no control over what happens to you.

The man is in control, and he does not need to offer reasons for anything he does with his cum dumpster.
