My mother in law was just 18 when she gave birth to my wife. They both look like sisters with some age difference. Her sizes are 36, 38, 40. Her thick arms and thighs are an oomph factor in her.
Initially I never had any sexual thoughts on her. My wife and I have healthy sexual relationship. Though she is little less interested in sex, after a small seducing she will be a tigress on bed.
My wife used to keep bragging about her mother's shrewdness and her ability in handling tight situations. I have an inclination for incest and I like shrewd women. This started a spark towards my mother in law.
Whenever we visited my wife's home or whenever my MIL visited us, I started noticing her. I ensured that no-one noticed me ogling at her. She used to be casual in dressing at home, like the saree end dropping off sometimes during work etc. Always wears sarees.
The first bomb happened when we visited our MIL's home. It's a typical village home with 2 bathrooms outside the house. One for bathing and the other for defecation.
One night I was sitting idly at their home after dinner. My wife was in the kitchen and my MIL was in bathroom. I thought of peeping but stopping thinking it to be risky.
