Mostly we used missionary style so we would not throw the covers off the bed and freeze our asses. However, when the electricity came back on and the ...house heated up, we engaged in oral sex and tried out other different positions.When I fucked Mom in the ass, it was my first time at anal sex, and I found it every exciting to say the least. Mother told me that Daddy used to fuck her ass at least once a week, and that she really enjoyed having a man's dick up her ass. And when I fingered her clit. I think Alex genuinely enjoyed the workout as she asked Val if she could come and practice again, hell I was fine with it as Alex seemed willing to learn and I was more than willing to teach.I was still naked when Alex left and was standing in the lounge when Val returned.She reached out to hug me and straight away I felt her nipples digging into my chest as we embraced. My cock was still semi hard and the closeness of Val was making it press into her belly and I could feel the fabric of her. I had just done the most akwars thing that could possibly happen, my sister felt my boner. After about five minutes I went upstairs to apologize when I stopped at her door and heard her on the phone to her best friend Orla on loud speaker, before going in I pressed me ear against the door to hear what she was saying.“ You better you slut you know you love a cock remember John at camp you fucked him and his dad” I couldn’t believe it my sister was a slut she must be if all Orla was saying true I. ‘You are not afraid now, are you? After that remarkable speech about my shallow personality, you are not afraid that I might however have some effect on you,’ he said. A strange lump formed in her throat. How did it come to this? All she had wanted was to enjoy a decent evening but this man never seemed to let any stone unturned in her life. Why did he not just leave her be? She was not interested, was this too big to understand? It had always worked before. Her cold nature and rude behavior.
