Sister in law going through a divorce and her brother in law(myself) start texting and flirting.

Yes, you read that right, Gentlemen. I've always had an attraction to my sister-in-law. In some ways she is more attractive than my wife (her sister)

Currently she is going thru a kinda ugly divorce and when she was married she didn't get the attention she deserved or wanted.

She knows my wife and I are not on best terms. We talk occasionally as she's going thru a lot with the divorce, kids,

getting fired from her job, etc. I want to show her attention but not go too far.

She lives 3.5 hours away so I can't just driver over and hangout with her or anything..recently we've exchanged some private pictures and videos of ourselves and a few weeks ago she called me at 4am randomly so I can watch her masturbate. I enjoyed it, but also shocked.

Sometimes I'll message her and ask for something sexy and sometimes she'll send it.

During these recent events I told her repeatedly I always had feelings for her both sexually and personally...and she finally admitted she USED to have feelings for me, but would not elaborate and made her she said USED...

So my dilemma is I want to show her attention. She deserves it. She's earned it, but she never got it...and I try to give my wife all the attention I can give, but it's nothing to her.

I'm leading the charge on the flirting and asking for pics, etc...Yes, morally I know it's wrong, but my marriage sucks. My wife thinks it's perfect, but far from it and my wife won't certainly send me sexy stuff or talk sexy...I'm a trucker. I'm gone 6 days a week. I want attention also and I'm getting more from my SIL than my wife.

I'm just seeking for advice.
