Taking advantage of the situation
Will try to make this brief. I've had a strong sexual attraction and desire to and for my hot, beautiful older sister for years. She's known, and to a good degree, not only allowed it, but participated.
She's been having marriage problems for 2 years or so, and it's gotten worse. I've paid her more attention and seem to have returned to my/our previous chase-flirt-get physical behaviors. Thanksgiving, at her house, as my brother in law slept (they weren't speaking for days anyway), I lustfully watched as hot sister raised her shirt to just below her 34C tits, in mock "ahh..long day" stretch. Her long, burgundy nails atop soft, tanned skin was too much for me.
Getting up from my kitchen chair, I told her to "stay like that". She did, and asked why. Without a word, I kissed, licked, and tasted her nearly-bare upper body, sending her shirt above her boobs and ending with a deep, seconds-long kiss to her lips. ALL with her asleep/Vodka'd-up husband no more than 10 feet away!
Later on, I followed her outside while she smoked. We joked about the kitchen fun, and she mentioned not being touched by "fatass" in months. Told her I could fill that void. We've met up twice since then. Am I taking advantage of the situation, or simply filling a need for someone I love on much more than a sister level?
I'm also recently divorced, and, while have dated other women, hot older sister is the ONLY one I think about or gets me going (if you know what I mean)..
