Caught Mom Pleasing My Spouse

I'm sort of a newlywed. I'm on my second marriage. I thought he respected me but I was wrong. All he was interested in is having sex with me because of my long boobs and hairy snatch. I should of known from our sexual activity. He's kind of aggressive and demanding. Keeps telling me to give him a blow job and let him eat my hairy snatch which I think is disgusting. For some reason he stopped pressuring me. I thought it was our role play of him r****g me and fucking my tied tits. I was wrong because my mom crossed the line and gave her son-in-law what he wanted from me. When I came back from work training I caught my mom and my husband in our bedroom. She was blowing him while he had his face in her pussy. It was an disgusting scene. All hell broke loose in the bedroom.
When I calmed down I listened to their explanation. Granted I denied my husband oral sex and my mom was trying to keep my marriage together. Few days went by and I came up with a solution. I told them no more secrete sex affairs. I told them they could do disgusting oral taboo sex in the bedroom when I'm home. Just oral, no fucking !
