I think that when you're being made to do something degrading by your bull, or when he's fucking you even if you don't feel like it and he's doing it too hard and it hurts, or when he humiliates you in front of other people, maybe lets his friends use you...he's no "abusing" you. He's not necessarily teaching you a lesson. I think he's being himself, and the slut wife or her cuck are not being abused, mistreated or anything. they're just showing some respect, and commitment o the lifestyle they chose. Things in life aren't always easy...neither they are an interracial cuckold relationship.
