So whenever my wife is asleep and doesn't want to have sex I go in my computer room and stroke to some porn. One of these nights I didn't realize it but my daughter must've woken and when I went to wipe up the mess I made she was right there. Embarrassed mutually she turned around and quickly went to to her room. Not trying to relive the embarrassment I never said anything about it, praying she wouldn't tell my wife how I carelessly let our 19 year old daughter see me jerking off to internet porn. After that I was more careful and made sure the door was fully closed so I'd hear it open if anyone came in. A few weeks later everyone was out doing there thing and I took my laptop to my room and was at it again. Not realizing the time my daughter must've came home and the door opens. I didn't know who it was, my wife, my son, my daughter so I frantically pulled the covers up as if that'd do much anyway. It was my daughter and she definitely knew because she stood there for a good 2 minutes just looking at me and said just wanted to tell you I was home. Stormed off and slammed my door. It was ruined now and I didn't get to finish. So I heard the shower running and figured I had at least a good half hour as she takes long showers to try and finish my session. I pull the site back up and begin, not a second later I hear her yell for me, dad I forgot to tell you mom said to figure out dinner her and my son were stopping to eat after getting done with shopping. I yelled back OK great. A few more seconds go by and I hear her again dad there's no clean towels can you bring me a towel please. So I guess finishing wasn't in the cards today. I got up tucked my hard on and got a towel. I knocked and said I got you your towel she cracked the door to grab it and it fell. As I went to pick it up the door opens more and she's there fully exposed. She said I'm so clumsy but at least since I saw you it's only fair that you see me. I handed her the towel and walked out. How the hell was i turned on by my 16 year old daughters naked wet body? I called to order us Chinese and when it came I yelled for her to come down. She had on her usual sleep attire which consisted of ridiculously short sleep dress and thin straps. She had bought it to go out but we'd never let her leave the house like that. During our dinner she said dad you know I know you still jerk off, I already caught you, why do you hide it? I told her because it's embarrassing and a daughter shouldn't ever see her father like that. Jokingly I said you should never see any man like that. She said yeah well you know it's normal for people to do those things you shouldn't have to hide it. Again I pushed the whole you're my daughter thing. She said yeah I know that's why I let you see me naked before, so we're wveb. Besides I don't care if you jerk off, I'm not mom you know? It's cool with me, you shouldn't have to hide it. She goes by the way, when you saw me naked did I look as good as the girls on the websites you go to? I quickly told her eat your dinner this conversation is over and I was beat red. She stayed quiet and got up to grab a drink. She asked if I wanted anything and when I went to turn my head and respond she was bent over the refrigerator and I could see her ass and part of her lips. I must've stuttered when I asked for iced tea cause she giggled and said oops didn't realize I was giving you another show. Guess that means you owe me one now. She came back to the table and spilt the glass of water she had gotten herself so when she went to wipe it up I had a clear view of her breasts now. I couldn't help but to stare and she glanced up and caught me dead to rights. She just smiled and continued to wipe up the water where I had a clear view down her dress at her breasts but she never broke eye contact. She said oh daddy they're just tits every woman has them but I know I'm you're daughter blah blah blah. I said that's enough I'm not gonna tell you again, that's disgusting. She threw the napkins of water out and walked by and said oh it's so disgusting yet you seem to have enjoyed it, I said no it's disgusting not realizing I was erect as can be she pointed and said well I guess disgusting is what you're into then huh? No denying it I was definitely hard. She said you can go play with your computer if you want they probably won't be back for an hour. I didn't say a word got up, left my food where it was and went to the bedroom to watch TV. I wasn't going to stroke it after that. I hear my daughter call for me from her room so I get up to see what she wants and I knock she tells me to come in and she's laying there, legs spread masturbating. I said what the fuck is wrong with you? Don't you listen to me, some things a child shouldn't see and some things a parent doesn't need to know or see. I went to turn away and she said but I already saw you so I figured it was only right that you know I think it's OK. Daddy don't you want to watch me? With my back turned about to walk out I said even if I did your mother and brother could be back at any minute. She said yeah but we're upstairs the doors open we'll hear them come in duh dad come on don't be so stupid. Obviously when she decided to do this she had thought of the answers ahead of time. She said just watch I interrupted you before the least I can do is show you. I turned around and stood in her doorway as I watched firsthand my own flesh and back blood pleasure herself. I was so hard I didn't know what to do with myself and I guess she sensed it because she said I told you it's ok everyone does it, you can jerk off there's nothing wrong with it. In my mind I was saying yeah there is when it's your own daughter or child. She again said dad what are you gonna stand there with a hard on? Are you gonna make me stop what I'm doing and do it for you or are you going to do it yourself? I reached down my pants and started to stroke myself while witnessing my daughter run herself. It wasn't good enough becaus she said come on dad you see me, why can't I see you, what are you really that embarrassed for me to see you? I already have so who cares? I silently refused and just kept stroking underneath my pants. She slid down her thin dress straps and exposed her breasts I saw earlier as she cleaned the water she knocked over. Putting one hand back over her pussy she began to play with her breasts with the other. She even started to say things like oh daddy, do you like that? Do you like seeing me play with myself? Do you like how wet my pussy looks? Daddy do you like me watching me rub my pussy? Are you gonna cum for me daddy? Please daddy cum for me, please. Between her words and her moaning while saying then I began stroking even faster not knowing when my wife and son would be back I wanted to finish. She said you know it'd probably be easier if you just dropped your pants a little bit. I really wanted to just cum so I did just that. As soon as I did she started again, oh daddy your so big, oh daddy I'm so bad, I bet you'd feel so much better inside me instead of my fingers, please daddy, fuck me, fuck me daddy and don't ever stop. I can fuck you better than mommy, I know how to handle that big dick daddy, I know you want me to show you how bad I am daddy. I was about to cum at any minute and she got up got on her knees in front of me breasts exposed and said cum on my titties daddy, please, cum all over your little princesses titties, I want to feel your warm cum drip down my chest daddy, I said stop talking so I can finish, she stayed kneeling in front of me looking up at me jerking off, I really don't know why I hadn't cum and was getting beyond nervous my wife and son were bound to walk in at any second now. Maybe I just couldn't cum out of fear or the fact this is my fucking daughter in front of me acting like a complete slut. I tried closing my eyes thinking about the porn I'd watch and she started again, daddy what's the matter I'm not good enough? You don't wanna cum on my titties? Please daddy I wanna feel you, daddy let me help you, let me show you how bad I am daddy, please just cum all over my tits. Eyes still closed I feel her tongue on my balls, she started to ferociously lick my then too. I said what the fuck are you doing I'm about to cum, stop she said there must be a problem because you haven't came yet I just wanna help you daddy, that's all, let me help you. Now she's sucking my balls and I'm stroking away the sound of her sucking my balls was crazy, she said daddy let I want to taste it please, let me show you I can help, I know what you want daddy. I know you wanna cum, I wanna feel your cum on my tits, I wanna taste you daddy, cum for me. She started to tongue and suck my balls again and begin to put her hand over mine now, slowly releasing my hand with here and licked from my balls, up my shaft, to the top of my head and started to quite savagely suck me off. Not even using her hands at this point as they were behind my legs as she'd pull herself further down my dick. I freaked and told her to stop but didn't try to stop her it felt so good, my wife never goes down on me. Hadn't in years, she was so good too, not trying to ruin it by thinking much of it but it was evident my daughter had done this plenty of times before wirh God knows who. She stopped looked st me and said cum for me daddy, I want you to fill my mouth up with your cum, I'll swallow every last drop, I'll leave you dry daddy. Then she began to suck me off again but like earlier with the water when she kept eye contact as she saw me starring down her top she was looking up at me as she was sucking every last inch of my dick. Within seconds I came, hard and fast. You would've thought I hadn't cum in a decade, I guess not finishing earlier when she got home and walked in, then the hard on I had during dinner from seeing her bare ass and lips bent over the refrigerator I was really backed up. She didn't even choke as I literally heard her gulp and swallow everything I shot down her throat. She stopped licked me really good and got up. She said I told you I'd always be your little princess daddy, now get in the shower before they get back. I couldn't even muster up any words to say. I couldn't believe I just let this happen. After I showered my son and wife got home, when I went to say goodnight to my daughter and kiss her forehead she lifted her head up and kissed me on the lips. She said you owe me now dad so we can be even again, next time I don't just want to taste you, I want to feel you inside me and reached over and grabbed my dick and said goodnight tell mommy I love her. After that day it was never a normal family again. Whenever we were home alone we would have sex in some way shape or from depending on the time we had to do it. There's even been a few nights I'd leave the computer room door cracked late when my wife would be asleep and her brother would be out or sleeping also so she could sneak in and give me blowjobs while I watched porn. It's beyond any comprehension how this has gone on for as long as it has and how we never got caught. I'm for the most part very cautious but sometimes I know i clearly am starting at her or have a hard on when she's prancing around in her nighttime clothes or summer clothes. I can careless who believes this because that doesn't matter, as long as I have these moments with my daughter that's all that matters in the end. I just have no one to talk to or share these secrets with and this is how I can confess to it without consequences or it weighing on my chest. Regardless of the nature of wrong here when we're together it's humanly impossible for something so magical to possibly be wrong. She is now about to turn 18 and I'm praying secretly she goes to school close to here so she can live home. Otherwise I'm going to have to figure out how to carry this on.
