Housekeeper

I was a late child, and my parents were quite well off and I was doing okay in almost everything except relationship. Being sent to boarding school and very few opportunities to meet girls growing up, meant I was nervous around them. Going to university I (22) still had very little interaction with them, more by choice than any other reason, I played sport but avoided parties. Living a home with my parents and the live-in housekeeper (51), my parents were always travelling somewhere or another. So, it was just the housekeeper and me, she was a nice woman always happy. She caught me several times masturbating and it didn't shock her or her tell my parents. But last Christmas I was to be home alone with the housekeeper, my parents were going away as was usual for them. I was asked what I wanted for Christmas dinner and as usual said whatever you cook. Being in boarding school taught me to eat what I was given. As usual when my parents were away, I ate in the kitchen with the housekeeper. Christmas eve I was in my room just starting to masturbate and the housekeeper caught me again. But this time she decided to use the opportunity to her advantage and get fucked. She got horny now and then herself and as she had no boyfriend/lover I was the next best thing. I was shocked a little at first but went along with what she wanted and thus started my sex life. Regular sex followed even when my parents were home, fucking the housekeeper is all the sex I get. But it's regular and she has taught me a great deal. My parent both in their sixties, are happy to let me do what I want and don't try and run my life. Neither knows of my sexual relationship the housekeeper.
