My Sister and Ram walked into the house and went straight into the room we shared.I knew they were going to have sex so I increased the volume and wat...hed the movie. Around that time, I was single and had been like that since I got out of a relationship with a much elder married man. His wife had found out about us and had treatened to divorce him and he had to stop seeing me.He was ok in bed but he was into that bondage stuff and I did not really like being physically abused. I had not had sex. Then she prepared breakfast we eat together after that she continued cleaning and I went out to buy cooking stuffs for rest of the days.We had lunch continued cleaning she was cleaning the floor her cleavage was clearly visible her huge navel was also visible I become slightly turn on by her huge boobs I started fantasying about them sucking,licking them I was staring at them for a long time she was cleaning and talking to me but my mind was filled with her huge melons suddenly she caught me. Had any second thoughts about this since we last met?”“A few dozen,” I said, smiling wanly. “Are you sure you don’t mind me posing in my undies for your daughter?”“Why would I mind? I trust you.”“Even though you know I’m not gay anymore?”She smiled and slapped me on one shoulder.“She has to learn about men somewhere. Better from you than some furtive boy full of hormones.”“I’ll try to behave myself,” I said.“I have no doubt you’ll be the ultimate gentleman.” She frowned. “If anything does. So, I keep saying no. But, slowly, the thought has started working it’s way into my fantasies when I played with myself, which I do every night and some mornings. I haven’t had sex in almost a year and it seemed like maybe a girl would be really good at it. So, last night we were up late just talking in my basement TV room and for the first time I found it super hot to imagine. I kept glancing down at her neck and her breasts. I've seen her topless before. She has gray brown nipples that are.
