When my second wife was pregnant her widowed mother needed a place to stay. Liz had never gotten along with her mother and really didn't care about her problems. I told her that we had a sofa bed and we couldn't let Linda be homeless.
Liz had told me that her mother shaved her pussy. I had seen pictures of her when she was younger and she had a nice trim figure. When I thought of her unshaved cunt I was hoping that she being a widow she might be horny.
Nothing happened for the first week or so. She would go out on the balcony and chain smoke seven or eight cigarettes and come back in for 30 minutes. She would do this all night. Linda and I would talk about anything in general. I could tell that she wasn't as innocent as you would think a woman pushing 60 would be.
Liz liked to go to bed early all the time leaving us alone. One night we were watching TV together. I called up the cable company and ordered a porno movie. Linda and I were watching and making comments to each other. She got up to go to the bathroom and left me alone in the living room. When she came back, instead of sitting back down on the couch, she sat in a big chair closer to my end of the couch. I had unbuttoned my shorts and pulled my zipper down. I pulled my shirt down over my cock so nothing looked amiss. We continued to watch the movie.
I told her that since Liz was pregnant, the only sex in the house was what was on TV. She sighed and said that she knew what I meant. I whispered to her "Usually I'll masturbate out here in the living room but since you're here I can't do that". I had let my shirt ride up but in the dimly lit room she couldn't see my erect cock poking out of my fly.
"Do you want me to go out on the balcony"? Linda inquired.
"Actually, I'd like you to help", I replied and cupped my balls. Just then the TV illuminated the room so she could see all seven inches of hard cock. She didn't say a word but came over to the couch and started to stroke my cock. It might've been since she had seen one but she hadn't forgot how they worked. I slid my shorts down and she took her other hand and started to rub my balls.
