I was thinking how lucky I was to have this chance. My wife was at work, and here I was, still at home, on leave, and waiting for my mother-in-law to come over. Ever since my father-in-law was diagnosed as having diabetes, and consequently, daily inoculations, his sex-drive had diminished so much as to be practically non-existent. The idea of taking Viagra to help out never entered his mind.
So naturally, Joan, my mother-in-law, still a very youngish fifty year old, was as horny as hell.
Joking between us, the previous week I remarked upon what a pity to let such a sexy body go to waste. I offered, jokingly to help her, but the twinkle in her eye showed me that she did not take it as a laughing matter.
I told her that today, Monday, I would be on leave from work. At home, with a promise that I would do anything that she wanted.
I was wondering whether she would take up the challenge, but on Sunday night, when they came over to visit, she cornered me in the kitchen, and asked if the offer was still open. I assured her it most assuredly was, as I hugged her to me, hard-on grinding against her light dress and onto her body.
The door clicked open, and I heard her footsteps coming up the stairs. I was still in bed, all the lights were off, and as she opened the bedroom door, Joan asked if I was awake.
I whispered that I had been waiting for her to come over.
