It was the big day, dad was leaving for his business trip. Kayla was moving back home today, so we could have mom all to ourselves for the week. Mom had gotten used to the rules I gave her. No clothes were to be worn unless dad or someone else was in the house, Her holes were available to me 24/7/365.25, and only I got to decide if and when she could fuck dad, but she did have to blow him at least once a week. I had never seen dad happier. Mom still didn't know that it was Kayla I had ass fucked before she sucked me off that night. Today was the day she would find out. As soon as she got home from the airport, before getting out of her car, she stripped off her clothes. She walked into the house from the garage and found me sitting in the living room, using the web browser on the TV to pull up my account on a website known for having MILFs getting caught fucking their stepdaughter's boyfriend and convincing their stepdaughter to join in. I knew the one I wanted, it starred Corey Chase as a family therapist, and her children are always fighting. So she has them do some things together to try and get them to bond. The therapy works too well and they bond at the genitals, and Cory as mom joins in the fun. I started playing the movie, and mom having learned what I expected, dropped to her knees and began to nuzzle and nibble on my cock making it start to get hard. About 10 minutes in, I saw Kayla quietly enter the house and walk into the indian living room, standing behind mom. At this point in the movie, Cory catches her children fucking, Kayla taking on the role of Cory quotes the movie, “What the hell is going on here? Why are you blowing him?” Mom jumps up and spins around and sees Kayla standing there fully dressed. Her entire body is red and her mouth is opening and closing trying to cum up with something to say to her daughter after being caught sucking her sons cock. “Bitch, did I say stop?” I ask her. Mom knowing my tone instantly drops to her knees and takes me in her mouth. I could tell from the quality of her blow job she was distracted. “Oh mom, I guess you can go kiss your daughter hello. Why don't you do that.” I say winking at Kayla. Mom jumps up and starts walking to Kayla. “Give her a nice wet tongue kiss...” mom freezes and looks at me in horror, “...On her asshole,” I finish my sentence. Mom glares at me part of her wanting to argue, but we both had learned she loves to be humiliated, and this was the most humiliating thing I had done to her since the first time I fucked her. “Yeah mom, cum lick my asshole. It's not like you haven't tasted it before.” Mom spun away from me and looked at Kayla in confusion. “Thank you, Mistress.” I said in a shaking voice, my brain seared with the images of the crowd’s predatory faces. “Well, believe me it was a struggle. Julie collected her coat and covering herself helped Sue rearrange her clothing as they made their way a little unsteadily back to the table. “Boom, bitch.” he proudly spat, making finger guns towards the school. Today the images were neither the lesbian images from the Monday nor the hetero porn from Tuesday. Her German accent was at its thickest when she was in the throes of passion. She giggled “Terry my pussy just said thank you” Lou asked I guess your ass did the same thing right”? She noticed the girl wasn’t wearing any make-up at all, and it suited her natural beauty well. “Just like this.” He said. Humping deep into me. “I’m close too Dave.” My father groans. My tongue rimmed her and then I would spear the tip between the small little hole of her and pushed as deep as I could into the little taboo hole of hers. Wood splintered. Before she could think of entering I shut it behind me and wouldn’t let her pass as I kept laughing. You have a skill.” “Maybe it’s their little game. Ukobach indian hissed as he made another pass at me barely getting half way through. Then she leaps towards another sister, Bonnie, and kisses her and then Jaimie next to her sharing the semen on her lips and smearing the cum on her chest onto the other girls clothes. “But I am going to get pregnant” she cried, as if it was the worst thing that could happen.
