Again: were some errors because of some word and I'm not a daughter in law but perhabs you can advise me.
I've made a terrible stupid mistake. My wife works in nursing and has regular night shifts. My mother, a widow of 56 years, is sometimes staying with us. Although she is somewhat meddlesome I can get along with her. She has sometimes some sexually explicit remarks as we were alone during night shifts my wife but I saw it more as a joke. My mother in law is, unlike my wife, a strong woman and I have to confess that because of her comments I have occasionally fantasized about her.
One night, when my wife was on night duty, and I have some doozed asleep, I felt someone beside me cringe. It was my mother in law who, without talking to me began to stroke my body. It excited me and instead of sending her away I responded to her and we ended up pretty violent sex.
Although it was very tasty, I afterwards had very much regret and want to leave it to those one-time.
My mother in law, however, thinks otherwise and threatens to tell my wife, if I don't 'serve' here more. She knows because of the 'one night stand' among others that I have a birthmark on my private part which she can tell my wife.
So I came into an impossible situation because of my stupidity and do not know how I can get out of here.
