Hello friend, my name is Samir and I am writing my true story. I am 33 married people now but I am writing the incident which I had when I was 23 with my step sister who is 3 years elder than me. She was also not married that time. My mom died when I was 15 and my father took me on. She was working in a bank and he met with a lady, Seema who transferred from some place to his office. She was a widow and had a daughter. They both been friends, then good friends and then lovers. They were spending time together and sometime we kids also be part of their trips. I used to call her daughter Di and she also loved me as brother and care for me. My dad and Seema got married and they bought a new house. My dad had given the existing house to me and Seema aunty had given to her daughter Sonia. It was a fair deal and they both didn’t want any financial mess in their relationships. We all four was staying in new house. Seema aunty and my dad decided to put us in same room which must help us to build a good relationship. We were staying as our parent wanted and everything was good by the time I had not seen her nude changing her clothes. It was Sunday and I went for jogging in morning. I left early and Sonia was sleeping that time. When I came back, she was in bathroom and I didn’t realize this. I entered suddenly in bathroom and got amazed. She was standing nude and doing shave of her body. She was so hot and very beautiful. Her shape was so sexy that anyone could seduced if see her nude body. Her figure was 36-30-36. Her body colour was white like milk and her nipples were so hot. My dick was erected instantly and I was trying to hide it. She saw me and smiled and came closer to me and pushed me out from bathroom and shut the door. I came out but still her sexy figure was infront of my eyes. My dick was pumping inside my lower and I was rubbing. She came out from bathroom and came close to me and said slowly in my ears. If you want to go to bathroom, you can go and laughed loudly hahahahahahah …I was feeling shy but it was true that I wanted to the masturbate. I said – you are thinking wrong. I just wanted to go for pee and entered instantly. I masturbate and took my bath and came out. I was not able to see her. We both went to dining table but she was cracking jokes on me. I was shy and our parent was not able to understand but they were happy that we had become friends and accepted each other. We had a good garden in our house and we made a plan to play badminton. Seema and I were on same side and she was catching me during play and she pressed my dick and butts many times. I noticed that she also wanted something from me. I also pressed her boobs and hips in reply. She didn’t get annoyed but apprising me. We had good launch and our parent went for sleep. I and Seema came to our room. I said – I am going to bath and got inside bathroom and intentionally not shut the door. I had been naked and started shower. I put my hands on well and closed my eyes. Suddenly I felt two hands on my dick coming from behind. I smiled and saw Seema was nude and was with me in shower. Her boobs were touching on my back and I could feel the hardness of tits. She was playing and pressing my dick. Her soft hands were doing masturbation and my dick was full erected and very hard. I turned to her and pushed her on wall and caught her hands very strongly so that she couldn’t move. I put my lips on her neck and she moaned aaaaaaaaaaaaaaaaa and then I started licking her neck and shoulders with my tongue. She was moving her legs. Her body was wet and I was licking her body. it was so horny and she was moaning in pleasure ahahahahahaha ooooooooooo… and then I put my lips on her lips and started pressing it and licking. I was licking her upper lip and then lower, then upper and then lower. She was doing same with me.I freed her hands then and she started playing with my hairs and forcing my head to lick her lips more. She sat on her knees and took my dick in her hands and put it in her mouth. It was so hot and she was seducing me well. My dick was full erected and got its complete strength. She was smiling and licking the top of my dick. my breath was fast and strange sound was coming out with every breath aaaaaaaaaaaaa aaaaaaaaaaaaaaa ummmmmmmmmmmm .. I was saying Seema you are so hot..so sexy…. I love you baby. She was smiling and said now I want you in me. we both have almost same height. So I pulled her one legs and put her on commode. And put my dick on her pussy. She was taking support from wall and I stroked hard. As my dick went inside she started shouting aaaaaaaaaaaaaaa oooooooooooooooooooo ahahahahaah slowly, push slowly and I was playing my strokes. In 15 minute fuck I was cumming. I said where should I cum? She said – I am cumming too. Come inside me, don’t worry I had already “T” inside me. No worries for anything. With a fast and strongest stroke I released my all cum inside her pussy. She had cum same time. Our cum came out as her entrance was blocked. We both were kissing each other and very satisfied. I was kissing her and I started rubbing her asshole and pushing one finger in her asshole. She was doing same and pushing her finger in my asshole. We came out and had sex one more time. We had sexy in night also and I fucked her asshole. She also fucked mine too with dildo which she uses to fuck her. We had sex no so often but we were happy with each other.
