My mother in law moved in with us last year when her brother, that she was living with, passed away. She is a little overweight but carries it well. She is 75, but looks 55. I had never really thought about having sex with her, especially because she is my wife's mother. But, for the past few weeks, she has been coming out of her room with sexy night clothes on when my wife is not here.

I didn't really think much of it until last night my wife had went to bed and my mother in law came out of her room with only a robe on and it was falling open in the front. She started asking me if I had to go into work or if I was working from home tomorrow. I told her that I was going to work from home. She smiled real big and said she would make me some lunch tomorrow. While she was talking, she was shifting back and forth and her robe opened up more with each shuffle. After a couple minutes of this, her robe was opened up far enough for me to see the inside of her big tits, almost all the way over to both nipples, I continued to look down her body and saw her bush.

I haven't had sex with a woman that has a bush since I was in high school, but her bush really turned me on.

I felt my cock starting to get hard. I was wearing workout shorts and no underwear, so my shorts start to rise. As we kept talking I looked up at her and her eyes were glued to my rising shorts. She reached up and pulled her robe all the way open showing me her beautiful breasts as she pulled it back closed and said sorry I didn't realize my robe was coming open. I don't know why but I said I didn't mind with a smile. She walked over by me on her way to her room and said I see your cock likes my body and leaned down and kissed me on the check and said see you in the morning.

I went to bed with my head spinning, I didn't know what to think. I didn't really sleep at all.

This morning when I went into the kitchen to get some coffee, my mother in law came out of her room with the same robe loosely draped over her with it not even tied up. The first thing she said was, is Dana (my wife) gone to work yet. I told her she was, she smiled and walked over to me with her robe open enough for me to see that bush and her tits too.

She got a cup of coffee and stood there and started telling me that she knew that Dana wasn't taking care of my needs and that she didn't want me to stray so she had decided to help me out if I was ok with it.

She then moved over to me and said I don't want you to answer that until she did one thing. With that she told me to sit up on the island in the kitchen, I did, she pulled my shorts down and started playing with my already hard cock and was telling me how lucky Dana was to have a husband with such a nice big hard cock to fuck.

She leaned down and started licking the head of my cock, it would jump every time her tongue touched it. Then in one motion she took all of my 8 inch cock into her mouth and down her throat. It was amazing, she didn't have her teeth in so there was no teeth scraping my cock and she was going to town deep throating me over and over again.

She was sucking my cock and was playing with and pinching her nipples.

Well it didn't take me long and I was about to cum. She was still going at it, I warned her that I was about to cum, this made her suck harder.

When I started cumming, she didn't miss a beat, she swallowed every drop, she continued lightly sucking until all the cum was out of me and in her.

She stood up and was using her fingers to make sure she got all the cum off of her lips and put it in her mouth.

She then asked if I was ok with me and her playing while Dana was at work.

I said I have no problem with that as long as Dana doesn't find out. She grabbed my cock with one hand and balls with the other and started to massage them and said I can keep a secret if you can....I can't wait until tomorrow....
