My sister "Radha" is 21 years old and studying in B.Com (P). She has a very good and sexy figure 36-27-38. I never had a bad intention about her but one day when my Mom and Dad had gone to hometown for a week and we both were alone at home. I was coming back from my friend's house and Radha was alone at home. I knock the door but there was no response from inside then I again knock the door. After a long gap Radha opened the door. I was just shocked to see that she has not wear anything, she just had covered herself by a towel as she must be in bathroom and on my knocking she directly come here to open the door. Well, she went back to bathroom to take some more baths. And I am till thinking about her. First time in life I have seen her in such a position, her light brown well- shaped thighs and her well-firmed 36D sized boobs. How sexy she was. My Lund is start standing and going harder and harder. But at that day I have not done anything except whole day I was dreaming about having sex with her. We usually drink milk in the night at the time of slipping. Then next day I decided to put some sleeping pills in her milk. In the night I done the same and we both have gone to our rooms for sleeping. After one hour I come back in her room, she was in highly deep sleeping as I put 5 pills in her milk glass. I went near to her bad and checked her that is she really in deep sleep or not. I am absolutely correct. At that time you cannot imagine my happiness as I am going to touch a gal's body first time in my life. I slowly pulled up her shirt upwards; she has not wearing anything inside. I look her boobs 36D were really very magnificent and well firmed like a big apples. First I take my hand on her left boob and start pressing it (I was in heaven) then I took my second hand to other one boob and start pressing them very slowly as I was very nervous. At this time my Lund is rock hard position and ready to tear anything. Then I slowly open the knot of her salwar's rope and then pull it to down, she has wore a light pink color panty. I slowly – slowly took off her panty too. Wooooooooooowwww what a look, she has very long and busy hairs on her choot. The hairs were really very long I haven't ever seen in my life. I put aside her cunt lips and put my middle finger inside her choot. There was really very hot. While my other hand is working on her boobs and my mouth is with her mouth. Now I couldn't hold myself anymore then I open my pajama and hold my Lund in my hand. First I touched it with her boobs and then on her cunt lips. I took her legs asides and then I put my saliva on my Lund and placed it on her choot's chhed. I slowly pushed myself inside her. But what is this; she starts moving and unfortunately she woke up and when she saw me to do all this shit. She screamed and slapping me starts trying to keep herself away from me. But I have decide to fuck her then I push myself into her with full of my strength at this time she cry very loudly as her virginity was broke. She is begging me to leave her. But I'd not. I was still moving in her cunt. After some time I cummed inside her and it time she too cummed. I think she was also enjoying this but don't want to show me. I threaten her to not tell anybody about this incident. And then I put my Lund in her mouth and told her to suck it first she refuses for this but when I pressed her boobs very hardly then she agreed and started to suck my cock, after 5 or 7 minutes I again cummed inside her mouth. I was wondering that she had drunk all my cum. After all of these I felt very tired and fell down on her body. In the morning she told me with very shyness that she also enjoy this very much then I again fucked her many times in her choot and also fucked her from behind in her ass. I fucked Radha whole week at every location of house and in every type. Now she got married but we still have sex sometimes when we got chance.
