Backyard Skinny Dip

So, I haven't been on for a while because I had a boyfriend for a couple of months. Welp, I got dumped about a month ago for no reason what so ever...I think he was cheating. Anyways after crying one night in my room, my parents went out for dinner with their friends. I knew they wouldn't be home until late so I went in the fridge and took a few of my Mom's Corona's (i know i know I can't drink yet but IDGAF!). After about 3 I was starting to feel the buzz kicking in and to top it off a porn was playing on Cinemax. The couple was doing it in their spa and I thought it was so hot! Then I started thinking hey, we have a spa in the backyard and me being buzzed and now horny I went outside to go in the spa but didn't bring my bathing suit. I was too lazy to go back upstairs so I said fuck it and stripped down completely naked and go into the spa. Ours has a radio and lights that light the bottom so I had the music blasting, singing, and drinking not realizing how loud I must be. When I was just there in the moment I looked up at the neighbors house (which is also one of my friends) behind mine and I noticed that the blinds in one of the windows was bent like if someone had their fingers in it opening them up. I started wondering if someone was there because my friend said her and her mom were going out of town but then it clicked...it must be her dad!! He is super hot and looks kind of like Dr. Drew from TV. I thought shit I have beer bottles behind me, my loud singing and music Well the lights in his room turned on and I could clearly tell it was her Dad at that point. After a few minutes the light turned off and the blinds were all closed again but about five minutes later, I could see that he was peeking back out....Not knowing what to do, I just decided to open another beer lol. I figure if he tells, I might as well enjoy the drinks so I go and reach for another beer and realize...im fucking naked and he could probably see me with the lights in the spa on! I grabbed the beer and ducked back into the spa like it could really hide me. After a few minutes of thinking what to do, I said yolo! and leaned back and at this point my tits were sticking out of the water but clearly visible. I know I don't have the biggest boobs but they are still nice lol. The blinds were still open and I was getting hornier knowing he was watching so I spread my legs and started playing with myself under water. I started sliding my fingers inside me, tilting my head back, tits out of the water again, biting my lip so I don't make too much noise. I then got out of the spa and sat on the edge...legs spread with my feet on top of the spa, my pussy fully exposed facing my friends daddy in the window. My pussy was dripping wet and I started rubbing my clit...I could feel myself about to cum...I grabbed my right tit...pinched my nipple and grinded my pussy against my hand shaking as I cummed. I slid back into the spa, big smile on my face, grabbed the last bottle, drank the beer that was left then toasted in his direction and I waved. I started laughing not believing what I did, turned off the spa, grabbed my stuff and ran back inside. I haven't seen him yet but I talk to my friend (his daughter) every day and am ALWAYS thinking about how her daddy watched me.
