So this whole story started a while ago. After my parents got divorced, I ended up living with my dad alone (expect for our dog lol), and for a while he treated me like a normal father would treat their daughter, but then once I turned 18, he started looking at me differently, with a look of lust almost.

Quite frankly I didn't mind, him and I were pretty close, so I started to go along with it. I'd tease him every chance I got, talk about sexual stuff more often, ask him if I could sleep in the same bed as him cause I was cold, etc..

Then, one night we were watching a movie together, I was cuddled up with him, and I did the classic move, I wiggled my butt all over his dick, and I could feel him get hard instantly, I kept going, just to tease him, it got to the point where he was leaking pre-cum, he then decided to stop it, he gently moved me out of the way and we finished the movie.

After that, I decided to just screw it, I'm just gonna start teasing him a ton more, I'd walk around the house in just a bra and thong all day, and I caught him starting lots, it got to the point where I'd caught him so many times, he started to not even hide it, and just kept staring. Then one morning, I woke up and went to go make myself a coffee, and I saw him just sitting on the couch watching tv, and occasionally glancing over at me. I then heard him get up, stand behind me and then he slapped my ass really hard, I let out a soft moan, and he just said "You liked that, eh?", I of coursed laughed a bit then said yes. He then started doing this every day, basically like a part of our schedule, every day I'd wake up, go into the living room, and he'd come up behind me, slap my ass and then kiss me on the cheek.

But then came yesterday, my dad has been coming back from work very stressed recently, so I thought I'd help him "destress" a bit. He comes in like normal, I'm still wearing my underwear and he just sits on the couch, I go sit beside him and ask what's wrong, he just tells me about how work has been stressful and I just ask "Is there anything I can do to help you destress?" I say this whilst looking at his dick, which is slowly growing in his pants. He remains silent, but as I start to tie my hair up into a ponytail, he starts unbuckling his belt.

And as he pulled his pants down, I was filled with shock, I knew his dick was big, but seeing it without pants covering it was something else. I immediately get to work and start giving him a blowjob. A couple minutes later (not sure how many, wasn't really paying attention) he pulls out of my mouth and cums all over my face and it felt amazing. We laid there for about a minute, before we both got up and basically just continued on with our day.

Then later, we both decide its time to go to sleep, but I decide to sleep in his bed, which he accepts. He's laying in bed waiting for me, and I'm in my room getting changed, but I decide to surprise him and I walked in there naked. I walk into his room and cuddle with him, I start doing the thing where I wiggle up against his dick again and he immediately understands, he slides off his pants, puts on a condom (he brought one with him to bed, cause I guess he knew I was gonna do this lol) , and slowly sticks his dick into me, and it felt amazing.

He grabs onto my boobs and starts gently playing with them whilst he slowly goes in and out, and it felt so incredible. After about 15 minutes, I can feel an orgasm coming but right before it happens, he stops, just to tease me. We then decide to switch positions, and go doggystyle because why not.

And wow, we go for another 10 minutes and that might've been the best 10 minutes of my life, even after I finish, he continues using me for about a minute or so then pulls off the condom and cums all over my back, and although I wasn't expecting the cum, I very much enjoyed it. I get up to go to the washroom, and he lays there, I lay beside him in bed and we both fall asleep.

The next day, we continued our "schedule" and we didn't really mention what happened the day before. Think I might ask him if he wants anything tommorow, cause honestly I could not stop thinking about what we did and how good it felt.
