Why does a man have such an unusual fetish? ⇐ General

Why does a man have such an unusual fetish? After he finishes, he does not take out a member from me. And this is how we lie. And, as soon as I relax, and trust him, he beats me with his hand on the buttocks with all his strength. And watch for reactions. And the face is not cheerful or playful, but somehow strange. Evil rather.
