In the Closet...

I met someone online who shared my kink for impact play. We planned to meet at a hotel...but it was just us two, and my husband had no clue. The setup was perfect - soundproof room, heavy duty restraints...and then there he was in front of me, completely naked with his eyes blindfolded. His muscles tense as I started...striking him with the paddle, watching his skin turn red from the force. My breath came faster, feeling powerful and taboo...but scared too. Is this normal? Am I sick for craving it? What do you all think...
