Eight days ago after carrying my drunken wife to bed I also carried my drunken mother in law upto the guest bedroom. They'd been drinking all afternoon celebrating my wife getting a promotion and a huge pay rise. When I got home from work fairly late, they were both three sheets to the wind. Putting my mother in law down I saw that her skirt had ridden right up and that her panties had slipped to one side. In a split second I was on my knees and had my face pressed into her pussy. For nearly five minutes I eat out my mother in laws pussy and I swear she started to moan asking me to suck on her clit. I got scared as she became loud and stopped. The next morning (A Saturday) she thanked me for looking after her and then said "Your tongue was so good".
We haven't said anything to each other since, but I know if I asked my mother in law would let me lick her out again, possibly even fuck her. Now I have to decide if I'm going to do it, man this isn't easy.
