I selected the movie and played the movie on the laptop. At the beginning of the movie, there was a kinky scene between brother and sister. My mother ...as watching it focus fully. I already saw the movie and masturbated many times. So I was watching my mother, her nightie covered boobs, her white thighs and her reaction to the hot scenes.After seeing some of the hot sex scenes between brother and sister in the movie, my dick was standing like a hot rod and it is waiting for a huge release. My. I know you are close I move, my hand down your butt check and begin to play with your balls. I soon feel your balls tighten in my hand as you send load after load of juicy cum inside me. You lie next to me, your cock still semi hard. Your juicy sperm hasn’t yet flowed out of my sweet pussy yet. I whisper to you that I want you to taste it and then share it with me. You happily comply as you can’t wait to taste me again. Your tongue greedily waits at my wet opening waiting for your. My sister Amrita and I were both seeing all this. I looked at Amrita.She was smiling with her head held down. We ignored this and got on the train. I went to confirm my seat but it was not confirmed. The TC told me to ask the TTR in the train for a berth so I thought that I had to arrange for a seat anyhow.We got a seat just next to the door but only one person could sit there so she sat on my lap. At the next station, the tt got in our bogie and he gave us the top berth. While helping her to. I could see pre cum already oozing out the tip and I brought my mouth closer…He felt me licking his cockhead and he moaned softly. I started pushing my mouth down his shaft until his cock hit the back of my throat. He was now moaning loud in pleasure as I repositioned slightly to allow his cock to continue down my throat. I began sucking up and down his cock, one hand holding me steady while the other held the base of his cock. I pulled my head up and licked up and down his shaft. I paused to.
