First time wife[35] accepting lust for BBC[33]

Me[38] and wife[35] with kids sext with porn sometimes to spice up and its gone towards more of me sharing her with BBC guy. We have been doing this for 4 to 5 years and she also sometimes say she want to see me fuck other woman. So its all in sexting and to be honest i did offer her to have some massage from BBC for real but she said straight No. Last time when we were making out and not sexting then i was doing foreplay and telling how her thick body deserve BBC she told me that today instacart delivery driver was Black and he had big bulge. She said he was "very very sexy and handsome and seem to hv had huge cock. When i went down to pick up boxes he was there standing and looking at my boobs and ass and then i saw his bulge. When i stood back we had eye contact and he offered help with a smile and looked at my boobs. I said no, its Ok " She then says he seemed to want to come in and fuck me and to be honest she think she should have let him come in and help with boxes and some other things too????. Listening to this i fucked hard but cummed fast. Then couple of days later we sexted and i asked his pic from app and she sent right away. First time i felt that my loyal wife would fuck this guy if she get a chance. I was jealous and horny but guy was handsome and well built. If he comes back by chance, i think he will help her a lot and usually i m not home????
