I am going to write the story which happened two years back. At that time I was 27, My sister was 23. We were both singles. We had no intention of settling down. Our parents died years back. We lived together. But only for dinner, we interacted. Otherwise, we were not close. I did not if my sos had any boyfriend. She was average looking, her b**** were small. I had never seen her in this way until that night. I was sitting on the floor in the living room with my laptop, when she came and suggested we could have pizza for dinner. I told her to go for it. She took the phone and ordered for pizza. What happened later amazed me. She came towards with a bottle of beer and offered me: “how about beer? You like it na?” I was amazed. I said why not. I told her to join me in. She joined me in. Soon we started a conversation. She told about her work, friends etc. and was asking about my work. I did not know when was the last time we had a long conversation. The pizza came. We ate and continued with the beer. Did not even realise how time flied. During the whole evening we were sitting on the floor. She was wearing only a black transparent kurti. Her black Knickers and bra were clearly visible. When we saw the time, it's was quite late. My sis told me to take her to her room as she was too drunk to get on her feet. I lifted her up. She hugged her. I could feel her legs. I took her to her bed. I was about to lay her on the bed, when she pulled me on the bed. I was about to get up when she stopped me. Our faces were pretty close. I don't know what happened, we kissed. I know it's wrong. I pushed her away. I said it's wrong. She begged and plead to not to leave her. She said we are two consenting adults. She pulled me on her. I lost control and kissed her on her body. She was enjoying. She took off my shirt and kissed me on my body. I threw her on the bed, removed her clothes. She was completely naked. I caressed her body. She told me to f*** her. I opned her legs. She had a clean p****. I put my p**** in her v*****. She moaned. I f***** her till I cummed.
