My stepdaughter_(0)

My wife and I have been married for 15 years and we both have very successful careers, I am an adjuster for an insurance company and work from home and she is the director of a large company in the northeast. She spends a lot of time on the road at the many locations her company owns but we still find time to spend together and have, what I thought was, a good sex life. We have four children from previous marriages, I have two boys 30 and 32 and she has two girls 24 and 28. My two boys live a few states away and have families of their own and my wife’s oldest is in California working in the movie business as some kind of assistant to a producer. The only one still at home is her 24 year old Becca. She graduated from college as an art major and hasn’t been able to find a job that would pay enough for her to be independent. Becca is very good looking and has an incredible figure but whenever I suggest that she try to go into modeling or some other profession where she could take advantage of her natural assets, she responds with “Is that why you spent so much money sending me to college?” I see her point but my wife and I would still feel better if she was more independent. Its nice having her around when we both go out of town so she can house sit but I keep telling my wife that “that is what door locks are for”
I’ve never even thought about cheating on my wife and even though I have admired Becca’s figure on many occasions, I never thought of her in a sexual way but as they say Shit Happens.
It was a Saturday night and my wife was out of town till that Sunday. It was about seven o’clock and I was sitting in the living room watching the news when Becca came out of her room and walked toward me. She was wearing some tight jeans that showed off her great legs and ass and a tube top with her belly button showing. She was incredibly sexy looking and I was starring without realizing it.
“What” Becca said when she saw me starring.
“That’s quite an outfit” I said “Where are you off to?”
“Sandy, Trish and I are going to a new club that opened up last week”
“Who’s driving” I asked being the typical father figure.
“Trish is and don’t worry she’s smart enough not to drink.” She said making a face that told me that the question was not necessary.
“Doesn’t your boyfriend object to you going out to clubs dressed like that?
