I asked her to come in the evening and decorated my flat for her with balloons, roses and with our pics. When she came she was very happy to see all t...ese and gave me a kiss. I told her to sit in my room for a while. And brought a cake from the kitchen and placed all the candles and the called her to come in the hall. She was very happy and then she cut the cake and made eat from her hand and I did the same. Afterthat, she told she wants to drink (She told me earlier that she wanna get drunk on. After a while my sister flips around on her back facing up and my mother gets up and starts squatting over my sister face. My sister keeps licking my mother's butthole as more cum is dripping out. My mother then tells me to come closer in front of her. I did so and my mother started sucking on my cock getting the last few amounts of cum out while my sister is still licking and eating the cum out of her ass. After a few minutes my mother turns around and starts French kissing my sister. . I never told anyone what was going on. I noticed at night when dad was asleep she would open the safe in her room, and take out a blue book and write in it. I wondered what was in that book. I decided to spy on her a little. Dad was asleep, they had separate bed rooms, I never knew why. I noticed mom always looked in the desk drawer first, then opened her little safe. I figured he combination might be written in there. Now when she made an entry, she took out some pictures in a box in the safe. Than movie get started after some ten minutes I did my move and said to enjoy with me she allowed me freely with out thinking of RUHI I was surprised by her act. So like b4 calling her to theatre I told her not to wear anything inside and wear long skirt and come so that I can easily do my fingering and enjoy.
