Let's go back to the beginning. This all started 2 years ago. My wife (52) and I (60), along with her gorgeous daughter (27), live in a warm climate near a beach. Therefore, everyone wears tees and shorts most of the time. We love to have friends over pretty regularly to sit around the deck, fire pit, pool, etc, to enjoy drinks and grilling. My step-daughter, who I'll just call my daughter, enjoys a few drinks along with the rest of us from time to time. Little did I know at the time that she has an extremely high sex drive, that only gets stronger when she drinks to excess.
My best friend from out of state was visiting, so we threw a big party and invited one of my wife's girlfriends because she wanted to get her and my friend together. Well that part worked perfectly. My friend and hers hit it off wonderfully. They went for a long walk, then came back around dusk and decided to sit out front to have some privacy to talk.
Meanwhile, the rest of the party is still going on in our backyard. Everyone is getting pretty sloshed at this point and I'm finishing up with the grilling. One thing to note. When my wife gets drunk and then eats, it's like a switch is thrown and she immediately gets sleepy. We all sat down and ate, and at the end of dinner, said goodbye to all our friends except the 2 lovebirds. My wife said goodnight to the rest of us, and went to bed. That left our two friends and my daughter. The friends went back out front to talk more and enjoy the evening warmth.
My daughter and I stayed out back on the deck listening to music and still drinking. At some point, she got up and started dancing around the deck and I noticed that she was slowly moving closer to me. Oh yes, my daughter was wearing the thinnest tee shirt along with a pair of very worn, very short cutoff jeans shorts. She danced up to me and took my hand and told me to get up and dance with her. I was drunk enough to not care what I said, apparently, so I told her that I was enjoying watching her in her tight shorts wriggle her ass.
