I told her, “Mom also talks about how well organized you are and expects Priya to follow your example”. She sat calmly and listened to what I said...with a pleasing smile. Oh boy, she knew how to handle praise. I continued, “She often talks about how well maintained your things are, referring to your notebooks and way of dressing. In fact, Priya herself says that you keep your room in a pretty orderly fashion.” She was listening with apt attention all this while. And my cruel mind had started. After giving her daughter two more orgasms my sister then put her face in Crystal’s pussy and started to give her oral sex as well. Crystal really enjoyed that and held on tightly to her mother’s head. After a couple more orgasms Crystal was worn out however her mother wasn’t going to let her off that easy… Crystal had to return the favor.I watched as Crystal then gave her mother much the same treatment except that she was not all that good at it…however she was definitely willing to learn. As. By the looks of things she had had a few glasses of wine and was a little tipsy . We sat and talked for a while the hole time she kept catching me starring at her tits I could feel my big cock starting to get stiff in my pants and she knew it because she started to flash her little white panties so a decided fuck it I will go up for a shower then join her and see where this leads.When I was finished my shower I lay on top of the bed with just my towel on I must have lay for about 5 minutes. And later on started to chat for few min and it moved on for hours and moved on for a full day conversation and accepted me as a good friend. Finally there was chances were she was asking about my girl frndz and about love and bla bla things. Now I realized that I need act smart enough to take it in a right path. And finally we had an opp to speak about sex and I was shocked and took into surprise. My heartbeat was so fast and my dick was getting big as well and I told her I have watched some.
