As luck would have it he hadn’t pulled his curtains fully across and I could see fully into his room via the full length wardrobe mirrors and he had...on a small bedside light giving me full view.Debbie was under the covers with him, they where kissing, groping each other and rolling around in the bed, it wasn’t long before the covers fell off exposing their naked bodies entwined with each other. John was kissing Debbie on her neck and nibbling her earlobes, which she loves, and gradually kissed. Unable to control himself, she soon ejaculated a huge load of cum into the mouth of the good Sister. Sister Mary-Margaret began choking and swallowed quickly to avoid choking to death. She had no idea that this would happen and that she had just swallowed her first load of cum.The orgasm that Derek had just experience was simply indescribable. But he knew he wanted more. He wanted desperately to fuck the good Sister.Sister Mary-Margaret fell backwards and was now lying prone with her legs. She must have told Joe about my nipple sensitivity and now they both laugh as Joe orders me to be his girl. I speak in a high voice and say, “I am your girl.” They laugh hard and high five each other. “Puppy? Did I tell you to stop fondling his balls? I am gonna make you suck him off if you don’t shape up.” She knew that I do not have a gay bone in my body ( I do not have anything against it. I am just not it). She would love to test my obedience and have my mouth lose its virginity. . It was hard to concentrate on school work wondering if and when we would explore one another next.

Dad was also 10 years older than Mom and might have been losing interest in sex and the very same time my interest was at its peak. I had always been curious about mature women and my first nocturnal emission.
