I'm sorry Ma I cant help it when it starts to get hard. She like me said Oh its ok your getting to that age. He turned and walked toward his room and ...smiled at me and grabbed his dick as he passed me. I knew he was horny as hell because Iv been locking my bedroom door at night. I thought its the only way to keep from getting caught. Well we were getting low on groceries and I had to go into town for a pick up. Alex said he wanted to play his games and mom said she had some calls to take care. Feeling her pussy contracting around my dad’s cock and her ass tighten around my cock was the wildest feeling I’ve ever experienced. After she caught her breath she asked if we could switch again, so I got under Babs, slid my cock into her pussy and dad mounted her from behind. He lubed up and slid into ass a lot easier than I had. Again I could feel his cock sliding inside her but it was different this time and again I tried to develop an opposite rhythm than dad so that I could feel his cock. Ramu kept his hand on her shoulder and said please aunty. she said Ok go and close the door first. Ramu ran and closed the door of the room and when he came back my sister was on lying on the bed.Let me tell you about my sister, she was that time 37 years old, 5 feet six inches tall , 36 DD size breast, wheatish color big buttocks and thich thighs, she was average looking but very sexy, with lots of folds on her waist, her buttocks were best part of body after her breasts.Ramu came and looked. Her hands would gently fondle and massage the full tissue of her huge tits and each time she allowed the nipple to escape from between her lips, I could see it was darker and longer than before. I wished for sll the world that she had been lactating. It was the only thing that could have made the whole thing anymore erotic.Her hips began to rock back forth on the chair and I could see her breath become more labored as she watched me watching her. My cock was stirring to life again and I saw.
