Stepmom is unfaithful

My cheating mother-in-law and i have the evidence to prove it. so, as she comes out of the shower and gets ready for one of her famous outings with friends, i confront her with the truth. she tries to deny it but luckily i have proof. after seeing them, i expected screams but certainly not that she would drop her towel to show me her naked body. it's her own way of negotiating and despite my slight reluctance, i must admit that getting sucked off by this slut and fucking her in the marital bed is extremely enjoyable.
