The next morning again me and my sister were the early rises and had a fun idea for revealing the family secret to my girlfriend. First we went to our...parents room to tell them that we were about to tell her this morning everything so we went downstairs to the kitchen and started to cook some toast.Just before all the toast had been made, my girlfriend came down and walked over to us. She came over to me and when she went aroud the counter she saw all of us had no bottom cloths on and all had. Uske liye bhi chut ka intezam kar rakha hai.Mom: Aur mere kapde kisne kharide?Sharad: Tina ne.And my mother blushed. All this while, they were naked. I asked them.Me: Ye Tina kaun hai?Sharad: She is my step sister. In fact mere baap ki nazayaz beti hai. Mere baap ne ek randi se shaadi ka vada kar usse ye beti hui hai. She is 45. Teen baar shaadi hui hai and divorce bhi ho chhuka hai. Usne humare swagat ki tayyari kar rakhi hai.Just before entering the city, I stopped the car. My mother came out. I was fully satisfied & was very happy that all things are going in the right track & mom is living very happy.I observed a great change in her behavior she was wearing very transparent colorful clothes & for the first time I noticed that she was using lipsticks.On that day I was not feeling well,& come home early from the office. I opened the front door from my own key & when I entered the home I heard some whispering in mom bed room. To my surprise when I peeked in the crakes of window. A. ” She said, smiling knowingly. At this point I got another surprise. Mom unbuckled her t-shirt and lifted it off, and then she kicked off her shoes and pulled her shorts down. As she stepped out of her shorts she unfastened her bra. She cupped her voluptuous breasts, lifting and rubbing them for my benefit. Then she slowly pulled the straps down, but stopped just before allowing her huge tits to fall out. She pulled her elbows in and bent over; taking hold of her panties she slowly slid them.
