All of sudden I can hear my sister blaming her husband, “Can’t you fuck me for at least a few minutes?”Now I got to know that their sexual life ...s poor. The next day Monday after college I came home early. I thought I should try my luck today. I again entered sister’s room. I switched on the ac and switched off the light and lay down on the bed. I was not sleeping.After some time she came home. I can hear her entering the room. I acted like I was sleeping.
