Daddy's girl once again

Hey there. I want to post about something that happened between my Dad and I about 7 years ago. (I was 22 at the time and my Dad was 51). Him and I have always been close to each other for the longest time, I never thought twice about our relationship before this experience. During my early twenties (I'm 29 now) I was going through a pretty big slutty phase for a while, often meeting up with guys I met online, going out drinking with them, partying and whatnot. One weekend him and I went out to a popular winter resort together. Alone like we frequently did, one night him and I decided to stay in our lodge together and drink together, after a couple of beers, he remarked on my questionable lifestyle, asking me the age range of the guys I was meeting, I answered mostly guys around my age and a couple older guys, he then asked me if I had ever been with a much older guy, I asked for clarification, he took a large swig and asked if I had ever been with a guy around his age, I took a minute to reply eventually admitting that yes I've been with a guy in his 40s (I didn't want to say who exactly) he then proceeded to admit his feelings for me, saying that I was growing up to be such a smart, attractive young woman, after a few more minutes of talking I started noticing him get hard under his sweats, since we were both pretty drunk, I asked him what would he think of us doing something together, it took him not even two minutes to reply in the affirmative, that he would love to try something together, we started with making out and some heavy petting, which led to him undressing me, and I him which then led to us finally crossing that line, a father and daughter having sex.
