Natalie my wife of just over two years now has at least to me some strange Fantasies. She likes to tie my hands and legs to the bed posts and put a mask over my eyes and have wild sex with me like I'm a prisoner in a dungeon. I have to admit it has become very sexy even for me.
My wife's mother, Sandra, and her share the same birthday. Her mother a widow of ten years now looks more like an older sister than a soon to be 42 year old woman. She is hot! When she comes to visit if I'm not careful either watching or thinking about her I will get a hard-on.
Since their birthdays were on the same day my wife had invited her mother over to celebrate together. She also asked me to pretend I was very sleepy around 9:00 PM that way I could get in bed, naked of course and tie my legs to the bed posts so she could get the birthday present she wanted.
Sandra my mother-in-law seemed a little nervous all through dinner. When I'd gone into the kitchen earlier that evening I heard my wife saying to her mother.
"Remember mother you promised to do it for me." Natalie said to her mother.
"I will keep my promise to you." Sandra said to her.
They both shut up very quickly when they saw me. Both also showed from their faces they were embarrassed too. So I didn't ask any questions.
By 8:45 PM I was getting excited about the birthday present my wife wanted so I pretended to start yawning.
"Oh I'm so sorry about that I guess I'm more tired than I thought." I lied.'
"You do look tired dear. Maybe you should go to bed. He does look tired doesn't he mother?" My wife said.
"Yes, he does." My mother-in-law said looking even more nervous than early this evening.
I got in bed naked as requested and tied my legs to the bed posts. About two minutes later my wife came in the room and tied my hands and put the mask over my eyes.
"I'm going to talk to my mother for a few minutes before she leaves then I'll be right here for my present." She said with a little giggle.
