While I don't think it qualifies as degradation, my girlfriend's husband would wait outside the door in a comfortable armchair in chastity. She would be very loud, moaning, talking naughty, and begging for more. She'd also shout out "Oh my God, I LOVE your cock so much."

When we were done fucking and she was covered in sweat and cum, she had a little silver ringing bell. She'd make the bell go ding-a-ling-aling. And he'd come into the room with steamed wash clothes and ice cold drinks on a serving tray. She'd order him to freshen up her lover, and he'd gently and carefully clean up my genitals with warm wet washcloth and hand me a drink. She'd also have him use the washcloth on her most of the time.

For special occasions like his birthday, Christmas, or when he got a promotion or raise, she'd ask me if I wanted him to use his mouth instead. And then she'd order him to consume all the sexual fluids off my cock. She'd also sometimes make him eat the creampie I left inside her.

She even handed me a keychain with his chastity key on it. And told her husband if he wanted to be released to reclaim her, he'd have to ask me to unlock him. I never said no either. But it was part of the game they played and he loved it. I wouldn't unlock him until I was ready to leave though.

I think the big differentiation is that he politely asked and negotiated everything that was done. I was never rude or ugly to him either. I always thanked him for everything and made sure he was okay. Aftercare and talking about everything was required whenever we played like that.
