She is kinda slutty but nothing like my mom. It took about 2 months to talk my sister into a threesome. So I set it up when my wife was going to see h...r family. First my sister came over to the house. She asked me who the other woman was but I wouldn’t tell her. I gave her a drink and we sat on the sofa. After her third drink We started to play around on the sofa when our mom came in. At the time my sister was giving me a blowjob when I saw my mom. She was staring at us. I told my sister that. Woh thodi long holidays thi kyu ki bahut sare festivals ke liye hum logo ko almost one week ka holidays mil gaya tha. Uss din main bahut kush thi ki ab college one week nahi jana padega.Lekin andar se sad bhi thi ki kaise main one week ka time spend karungi jab mera breakup ho gaya hai. Uss din main aur mera boyfriend ek dusre se thodi si najre milaye lekin mujhe itna gusaa aata usko dekh kar ki woh mujhe kaise cheat kiya.Main usse najar bhi nahi milayi acche se aur main apne ghar aa gayi apne. Fuck for hours.“Good!” she moaned and then pushed me back. I settled on her desk. Her breasts rose and fell in her habit, large and heavy. She grabbed her dark skirts and drew them up. I shuddered at the sight of high heels and black stockings cladding lithe legs. “Mmm, I'm going to ride that cock so hard. You're bigger than any I remember.”I leaned back on my elbows, twisting her computer monitor to the side. It squeaked as its base rotated. “I want your sinful cunt on my dick, Sister.”She. I was about to cum so I took out and discharged on the floor. She got up and both of us cleaned ourselves and I asked her whether she was happy, she smiled and gave me a kiss. She asked me about when I was coming back from trip and in my reply she said that she would be doing everything then. I patted her pussy and she finished her chores and went back. My parent came early and I left for my biz trip after three days, once my job was over outside, I called my parents from there and let them.
