However growing upand reaching puberty the dynamic of our relationshipslowly yet surely started to change for the better.It was in 2005 when our love ...affair began. My parentshad left me alone in the home for the night safe inthe knowledge that Casper would look after me. Being a15 year old girl being left at home I was prettylimited as to what I could really do to entertainmyself. So I decided to take a bath and as alwaysCasper followed me in and sat next to the bath whilstI bathed. As I was. His finger slipped through instinctively and shockinglylanded right up against his anus. The thrill of feeling his fingeron his hot anus as he writhed in swishing, scented loveliness infront of the gilt mirror was something he had never felt before, andhis heart, already hammering with excitement, leapt even further. Hedid not know what it meant, but he was in transvestite heaven, anddid not care.Instinctively he removed and licked his fingers, slipped them back inbetween his buttocks, gently. I had just seen my daughter-in-law naked. Now she is standing in front of me with no bra, no panty, just in a skimpy nighty barely covering her. She has already noticed the big boner in my pajamas. I was just so shocked to respond to her.Riya came closer to me now. We both were standing close to each other. I am 5’11, and Riya is 5′ 6. Riya looked up to me, and I was looking down in her eyes. My eyes noticed her beautiful face. It went lower, trying to see her deep cleavage again. She noticed. Oh sis... I can't believe this" Fuck me brother, yeah fuck me hard, harder... do me good"He picked up his pace and he hammered me, his sister and his grandfather. Is there such thing as double incest? The fireworks were back again and again. The pleasure took up my mind.Afterward, there were no doubts, no regrets. Not after the first time, not after the fourth.Part FourI looked over at my grandson Jimmy he was sleeping. In his sister's body I had given him a hell of a work out. I slipped out of.
