My Wife's Secret Desire

I never imagined my wife would be into dominance and submission. It all started when she suggested we try out a dungeon in the basement that she had secretly set up weeks before I even noticed it existed. She was so taken with the idea of me being her submissive, bound to do whatever she commanded. At first, I was hesitant but her confidence was intoxicating. Now, every Friday night is our special time where she ties me up and commands me to pleasure her in ways that leave no room for interpretation or hesitation. Last weekend, we tried a new toy, a blindfold that she uses while riding me in the most intense way I've ever experienced. The sensation of her body moving so dominantly above mine was overwhelming. She controlled every angle and rhythm, never letting up until she reached an orgasmic climax that left both of us breathless. Am I alone here? Is this something others secretly do too without showing it on the outside?
