I finally got caught by my mother in law!! SeXStoRY

I found this story and want it to happen to me!! My wife and i went to visit my mother in law for the weekend, my wife went to out with her friends and her mum went to the shops.... so thats what i thought, i thought whilst i was alone i would have a wank so i stripped totally naked in the livivng room playing with my little boner, i suddenly felt like i was being watched and noticed out of the corner of my eye her mother stood watching me wank, i thought she would leave but she kept watching me, she also recorded me on her phone then all of a sudden she stormed in the room calling me a naughty "little" boy... I was shocked and couldnt move... then lead me to her bedroom by my cock laughing at it, she tied me down leaving exposed recordng me and waiting for her daughter to come home to humiliate me.... i also know she has told her mother about my small cock!! My wife came home to a little surprise waiting for her upstairs, they played with my small cock and left me tied for hours laughing and wiggling my cock!! The mother in law now blackmails me to strip naked for her and her friends when ever she wants... I love it!!
