I waited, walking slowly around the nicely decorated living room and was looking at the books and pictures on the large bookshelf when I heard Natasha...say “Hi” from across the room.I turned around and was stunned to see that Natasha was standing just at the bottom of the stairs, dressed only in a tee-shirt and thong underwear. I think that I stammered, at a loss for words. “I, um, what are you doing?” I finally managed.She stepped slowly, delicately into the living room towards me. “I was. I was like damn, what a women are you!!, I kissed her softly this time on her lips and then on her neck and was planting kisses everywhere possible.She was passionately feeling every bit of my kissing and with full of lust I am feeling every bit of her flesh.As I am kissing her, I slowly untied her bra hooks from inside and unwrapped her t-shirt.Wow!! I was totally lost with that sight and started sucking her big melons.I have taken her to the bedroom and got hold of her right boobs and was. Chachu was naked. He approached the girl lying on the bed with his big cock majestically pointing towards the ceiling.Nagma stole a quick look at him. Her eyes snapped wide open. "Chachi, chachu ka lund bahut barda hai. Meri choti se choot ke ched main kaisse gussega? (Chacu's cock is very big. How will it enter the small entrance of my cunt?)" Nagma said trying to sit up."You are lucky that chachu's cock is big because the bigger the cock more pleasure you'll get," chachi said pressing her. They almost try to feast on her nudity in their dreams. Anjali is a calm, shy girl who doesn’t speak with men often. But she speaks a lot with me as I am her only brother. We are kind of close almost like intimate friends. After she attained puberty, I pass comments on how pretty she is getting each day. She would give a shy smile as a reply. But I never imagined to bed my own sister which I am doing now. It all started when our parents left us alone as they have to attend a wedding out of.
