I got married about five years ago. My mother in law is very nice and for being in her 50's she looks pretty darn good. Anytime we get together she always hugs me and kisses me briefly on the lips. It was kind of weird for me but eventually I just got used to her ways. Her name is Elaine and she has been divorced for the past two years.

Elaine came over the other day she lives just a few miles down the road from us. My wife had gone to the store and I was just hanging out at the house. As usual Elaine gave me a hug and her kiss on my lips lingered a bit too long if you know what I mean?

We talked for a little bit and Elaine decided she would be on her way. I walked her to the door and she turned to give me the customary hug and kiss before leaving. When she put her lips to mine I opened my mouth slightly just to see what her response would be.

I didn't have to wait, her tongue slithered between my lips and we embraced as our mouths were locked in a sexual kiss almost instantly. She pushed her body against mine, her breasts pressed against my chest. Elaine's breathing became rapid at once as our tongues dueled with arousal.

Elaine was wearing a dress with a nice pair of heels, so she was almost eye level with me. I lifted the front of her dress and bent my right leg slightly. She knew exactly what to do, straddling my thigh now she began to grind her pussy against me as we continued to make out.

We continued to kiss up to the point that Elaine started to cum, she tore her mouth from mine and moaned with pleasure into my ear. Her hips thrust harder and clamped tightly around my thigh as she came a moment later. I could feel the wetness soaking into my jeans. She clawed my neck with her nails as her climax swept her away.

Elaine clung to me for several minutes breathing hard. She kept whispering how much she needed that. A few moments later Elaine backed away and saw the wet spot on my jeans. She quickly lifted her dress and I could see was wearing pantyhose but no panties.

She quickly excused herself and went to the bathroom. When she came out her legs were bare, she had removed the pantyhose. Elaine had her heels in hand and dropped them to the floor and stepped back into them just as my wife pulled into the drive way. Neither of us said anything, just a knowing smile between us.

We have done this several times since, and honestly I don't feel guilty even though I know I should. Sometimes I have to wonder if the chance presented it's self if we would end up in bed together?
