He had the image of his sister naked in the bath sponging her breasts in his mind as he masturbated faster and faster. His breathing increased as he o...gasmed, his body spasming. Ryan clenched his teeth from crying out in pleasure. After Ryan got his breath back he felt ashamed, hated himself because he just masturbated over his younger sister who was getting sexier every day. He put some trousers on and casually went over to the bathroom door and knocked."Are you decent?" he asked."I'm in the. Reaching down he unzipped his jeans, he grabbed one of her hands and placed it around his shaft, holding it there with his, rubbing it up and down. She swear she could feel the blood pumping into his dick helping it grow. He was beginning to moan now, his dick she thought was as hard as it would go, he was gyrating his hips to push his dick further into her hand. She gasped as he suddenly pushed her so she was laying down, it was hear she began to whimper, “please oh master, please don’t hurt. I could feel my cock getting harder everytime her tongue went up and down on my shaft and in no time, I knew I was going to cum.Sensing this, Ria stopped blowing me, looked up and said, “It’s your turn now”. Knowing exactly what she meant, we exchanged positions on the bed and I slowly took off her shorts and black panties to reveal a wet, pink pussy with tufts of black curly hair over it. She locked her legs around my shoulders and I slowly inserted my middle finger into her vagina and kept. I don't know what I would do without you here anyway." She placed her hand on his shoulder and gave it an affectionate squeeze."Great mom, why don't I keep you company while you fix dinner?" Ok." she smiled.She changed into one of his dad's old t-shirts but this time she wore some leggings underneath and was obviously still wearing her bra. Bobby wasn't too disappointed though, the combination of her more modest attire, his guilt and not least the fact his balls had been emptied meant he was.
