Female led relationships discussion

This afternoon Mistress put the slave into his leather harness with a butt plug. Then she laced him up in a leather corset. He was instructed to pull on his leather boots. We headed downstairs and started playing.. I flogged him playfully while he had to list 10 reasons why he felt fortunate to have a Mistress like me.. When we reached number eight, I went for another hit at his inner thigh but managed to catch his cock THROUGH the end of his cage!!!! He let out a sharp cry and dropped to his knees in tears. He even used his safe word!!!!!!!! I feel quite terrible now… I would never intentionally hurt my handsome slave. Really hurting someone does NOT excite me and doesn’t make me feel good at all. Apologies…
