How it started, I don't really know.
My wife (Pam) and I have a great relationship. We have sex at least 3 times a week maybe more. But things do get stale.
My mother-in-law (Debbie) comes and visits 2-3 times a year for a week long visit just to catch up. I have known her a long time, from when I was in high school. Debbie has a so-so body, but really likes to show off her more than ample 38D chest. We have always flirted.
When Debbie's second husband past away, we invited her to come and stay as long as she liked. Pam and I thought it would be a couple of weeks, however we realized she might want to move in after the third week. She started dropping subtle hints, so we finally asked her. She was overwhelmed by our generosity. I took off a week to get her moved down here. Debbie and I drove up with a rental van and loaded her stuff, spent the night in a motel and drove back on the third day. It went smoother than I thought and by the end of the third day, she was moved in.
After a few weeks, things seemed to get a little tense. I guess that is how it is when someone else moves into your home. We didn't realize the sacrifices we would make in order for her to feel a part of the family. Debbie walked into our room without announcing, and once or twice it was very uncomfortable. I started spending more and more of my home life in my room watching t.v. just for privacy.
One day, I was in the living room watching t.v. and Debbie was in her bathroom taking a shower. When she came out, she shuffled the 4 or 5 feet from the bathroom to her room with a towel draped around her front. When she went into her room, her butt was exposed to my prying eyes. My thoughts (I am a man) immediately went to wondering what the rest looked like, and what she was like in bed. Over the next few weeks, it became routine, she would shower, and I would sit on the couch waiting for her to come out and give me a glimpse. It always happened, except if Pam was home, then Debbie came out in a robe. I began to assume, she was doing it for me. I then started back to our old flirting games. She would go to her room and I would comment on her backside. She would then turn around and back into her room while looking directly into my eyes.
One day when getting out of my shower, I walked into my room naked to get dressed. I looked through the doorway and into the office. Debbie was sitting at the computer. She was partially hidden by some plants on the desk. I made some noise and watched her turn in my direction. She ducked down so I couldn't see her (so she thought) and she looked at me standing naked against the dresser. I continued to stand and getting a semi thinking about her watching me. She then got up and went back to her room. In a few moments, she walked across the family room with some clothes going to the utility room for washing. I just stood there sporting a half hard on while she walked back and forth. She kept looking over into the room and getting an eyeful. Debbie went back to the computer and again was looking at me. I started stroking my cock and thinking about sex with her and chewing on those nipples. She has those kind of nipples that look like your little finger is coming off the end of her tits. After a few more minutes she left and went back to her room. Now if you haven't noticed, I'm playing it safe. I don't want my mother-in-law screaming to my wife about how I'm a pervert. I still liked playing the game of flirt and see safely. This type of activity went on for over a month, with her watching, then me watching. It was fun, safe and exciting.
Then I lost my job after 8 years with the same company. Pam makes a good living, so I could take my time and find the right position. So now I'm home all day and Debbie goes out at about 10 or 11 everyday.
One morning, Pam had left for work and I was sitting at the breakfast table reading the paper. Debbie came in and was cooking her something to eat. She looked at the paper over my shoulder and leaned down. Her robe gaped open and I finally got a good look at those tits. They were magnificent, full with very dark circles around the nipples, the nipples were hard and extended. I looked them over and she stayed there for a minute. My cock started rising in my shorts.
Debbie whispered in my ear "My, my, looks like your a morning man."
I almost shot a load with her lips on my ear and that throaty whisper.
Again, playing it safe, I responded with "Yes I like to eat in the morning, then have a good workout."
Debbie finally broke the ice "Have you eaten yet, or would you like to eat me now?"
I turned my head and devoured her left tit. I sucked till I couldn't get anymore in my mouth.
Debbie moaned and quivered, she grabbed my hair and pulled me into her. Her nipple was just as I thought it would be, long thick and rubbery. I grazed it with my teeth causing Debbie to moan louder and with more grunting.
She pulled me away looked me in the eyes and said "We can't do this it's wrong."
