Today I am here with my real story. 1st of all I want to describe u about me and my sex partner. Her name is Hina she is my real younger sister at the time of that incident she was just of 17 and I was of 19. She had a figure of 32-26-36, round big ass and milkkish white body. We are 5 family members my father, my mother, me, my sister and at the end my younger brother Aftab. We have 2 years difference in all of our ages. At the time of that incident I was all free from my studies waiting for my results and my both bro and sis was studying, my father is working in a company and my mother is a normal house wife. I live in Karachi and it is very hard here to do sex but if u luck is with u will u get that chance easily. We have 4 rooms flat in the Karachi 1 is of my parents, 1 is for me and for my brother 3 one is for my sister and the last one is using as a drawing room. So come to the story One day when I got up in the morning I saw the watch it was 9 AM about the watch. I feel that no one is at the home caz I think that father had gone to his work, both bro and sis and gone to their studies and my mother may be gone to the market or may be some where else. I don't want to get off from my bed but I have to get off caz I had gave the time for meeting to my friend so I got off from the bed, took the towel and went for the bath room to take the bath but I found that the water tab is not working well and water is not coming out with that tap. So I had gone to my sister's room bathroom as I opened the door I got shocked to see her nude and taking bath with out locked the door. Her back was in front of me I can see her round milky white ass with some soap on it. I felt erection in my jeans suddenly she turned back and I could see her white boobs and nice shaved pussy. I got confused that what to do now so I ran back to my room and sat of the bed and thought what to do now. After 5 minutes she came back to my room with a towel that she had wrapped around her body. She came near to be and asked "when u waked up?" I said "just before 5 min when I had came to ur room". Then she again asked me that "why u had came to my room?" I said to her "my bathroom's water tab is not working well and I have to take the bath and I think that u r not in the home so I had come to u r bathroom to take bath" so she said "ohhhhhhhh". Then I said her that "please hina don't tell that to any one else" she said that "no bhiya don't worry I will not tell that u any one else buttttttttt I have one condition" I said "condition but what u r condition" she said me that "listen bhiya, that is not fair that u had seen me nude and I will leave u with out taking the advantage. I will not tell that to any one that u had came to my bathroom if u will see me u r nude body." I got shocked to here that words for my younger sister's mouth I said that "Hina u r my sister and I am u r brother how caz I show u my nude body. I had seen u r nude body in mistake." She said that "if u thinks that I am u r younger sister then y u r cock is in its full erection?" I got confused that what will be the answer of that question so I said to her that "I don't know about that and I can't do that think that u want from me" so she finally said that "ok no problem I will say mom and dad that u had came to my bathroom and u had tried to fuck me" that was the shocking sentences for me I can't believe to my ears that my sister is saying that words to me so I said that "ok I am ready to do that but promise me that u will not tell that u anyone" she said "ok I promise" and gave a naughty smile. I open my jeans and put it off and then my underwear now I was standing nude in front of my younger sister and my cock in its full erection (8 inches). She said that "bhiya u have a nice tool" replied to her "u also have nice figure and that was the lucky man who will touch it" she said "if u want to be that lucky man that u can touch then" and with that she took off her towel and throw it on the floor I said her that "no it is not the rite time mom will be back in any time" she told me that "she will come in the evening on 7 and aftab will come on 5 and it is 9:30 at that time and we have much time to do many things so come and don't waste time" and she lied on the bed. I also went to bed and got over her I gave her a kiss on her face and then I sucked her ears lob she was getting hot from that procedure and the speed of her breath was increased I kissed on her lips for about 5 minutes. After that I went to suck her boobs I placed my one hand on the one boob and my mouth on the other and started to suck them like a little child she was making sound in pleasure "ohhhhhhhhhhhhhh ahhhhhhhhhhhhh suck it hard bhiya ohhhhhhhhhhhhhhhhhhhh it feels good ohhhhhhhhhhhhhhhh eat my nipples bhiya" I bit on her nipples then I went to her second boob and sucked it for about 20 minutes. Then I told hina to take my cock in her mouth she told me that I will take it but don't throw u r cum in my mouth I told her OK then she took my cock in her mouth and gave me the blow job hummmmmmmmmmmmmm it was really very nice and had really enjoyed it very much and feel my self in the heaven. I can't describe my condition to u ppl. After about 5 minutes I had about to cum so I told hina to take out my cock caz I am about to cum she took my cock out from her mouth and I throw all my juice on her face and little bit in her mouth and she drink it a little bit she told me that its taste good I want to drink more and took my cock again in her mouth and give me a fine blow job again this time I took 10 mins to release my cum and that time I throw all my juice in her mouth and she drank all that with out wasting a single drop. After then I got down to her pussy and start linking it she was moaning in pleasure "ohhhhhhhhhhhhhhh ahhhhhhhhhhhhhhhhhh bhiya I was enjoying too much ohhhhhhhhhhhh my darling bhiya I love u so much.

I had sucked her pussy for 15 to 20 min and tasted her love juice. I started kissing and kissed it hard on her lips and with that I was also pressing her one boob with my one hand and with my second hand I was giving her finger fuck. She told me that bhiya I can't wait any more I want u r cock in my pussy. Fuck me bhiya fuck me hard I want to lose my virginity. I got down again to her pussy she opened her legs and gave me place I point out my cock to her pussy and tried to get in, in her pussy but her pussy was too tight I had applied some force she shouted and cried with pain "ohhhhh aaaaaaaa bhiya its paining aaaaaaaaahhhhhhhhhhh I don't want to be fucked plz bhiya put out u r cock from my pussy other wise I will die with pain" I said her "cool down hina it will pain u in start put u will enjoy that after some time" she told me "I don't want any enjoinment" but I didn't care of her and start given some powerful strokes and hina was shouting in pain after some stroke my cock went fully inside her pussy and some blood was coming out of her pussy I had broke her virginity. Now I was giving some strokes slowly now she was moaning in pleasure "ohhhhhhhhh ahhhhhhhhhh bhiya fuck me hard ahhhhhhhhhhhhhhh fuck me hard bhiya. Fast fast fast" I had increased my speed with her shouting for about 15 min I put off my cock in her pussy and throw my all cum in her mouth and boobs. After that I fucked her for an other time this time I entered my cock in her pussy and sleep with her for about 1 hour. We than took bath and during bathing I had fucked her again.
