I came home early from work the other day and as I walked up stairs to my bedroom I heard moaning coming from my mother-in-law's bedroom. She is 55 and I am 36. I had never heard her moaning like that so I opened her door and she was laying on her bed naked with her head cocked back and a hand between her legs fingering herself causing her to have an orgasm. She was so lost in her pleasure she didn't even notice me come in.

I stood there not knowing what to do. I have always thought my MIL was really sexy and since she had moved in with us a few months ago I had been fantasizing about fucking her. Now that I had seen her naked and moaning I really wanted to fuck her.

I just stood there watching her, she was really pumping two fingers into herself and moaning really sexy. As her hand left her pussy, it went searching for something on the bed and when she didn't find it she opened her eyes and saw me standing there watching her.

She had never shown any kind of sexual interest in me before, so I thought she would get mad or embarrassed, but she smiled and asked me if I like the show. I blurted out that I liked it very much. She said, "well come on the bed and join me." I said, "what about D, my wife, her daughter?" She replied, "I know she doesn't keep you satisfied and instead of you looking else where, I would rather keep it in the family. Besides, what she doesn't know, can't hurt her."

I hesitated for a moment, taking in her body, I never realized just how sexy she was, she had really nice breasts that didn't sag and her pussy was bare as a babies bottom and had really nice lips. As I walked over toward the bed, she got up on all fours and crawled to the edge of the bed and sat back on her feet with her legs spread to give me a good view of her pussy while reaching out to undo my pants. She had my cock out in a second and was stroking it. She had me hard in no time and was telling me how big and nice my cock was and that she couldn't wait to feel it squirting into her pussy. She took my hard cock into her mouth and deep throated me after a few up and downs. It felt amazing! Her daughter hardly ever deep throated me. I reached down and started playing with her nipples, this drove her crazy and made her suck my cock with even more vigor. So much that she had me ready to cum and when I told her, she pulled off my cock and said, "don't worry, I will make it hard again so you can fuck me real good." With that being said, she took me all the way down her throat and I grabbed the back of her head and started fucking her throat. It didn't take but a few strokes and I started shooting down her throat. She didn't miss a beat, and kept sucking me until I was completely empty and still kept sucking trying to get me hard again. I told her that if I ate her pussy I would get hard again.

She didn't waste anytime and laid back on the bed and I dove right in licking, sucking, nibbling, and fingering her hot wet pussy. It was much tighter than I thought it would be, it was much tighter than her daughters. When she started cumming, I was sucking on her clit with two fingers inside her pussy rubbing her g-spot, I slide a finger into her ass. This made her cum even harder, she was loving what I was doing to her.

While she was orgasming she yelled for me to put my big hard cock deep into her pussy. I got up and sure enough my cock was hard again and I shoved it into her in one motion. I started fucking her really hard and fast, this kept her orgasm going, when I sensed she was coming down from the orgasm, I pulled out and shoved my cock into her ass, she yelled out having another orgasm. She was bucking and grinding on my cock and it felt so good I started cumming in her ass.

After she came down for her multi-orgasm and I was going limp we both flopped down on the bed and then kissed for the first time. It was a really nice kiss. We laid there holding each other for a few minutes and talked about how much fun we were going to have with her living with us. I mentioned that we had to keep this hidden from D, she agreed.

We have fucked almost everyday since then and on the days we didn't fuck she at least sucked me off and ate my cum.

It is nice have two women to fuck at home, I can get used to this!
