Password from Dad

I live with dad (now 36) since my mother passed away when I was 3. He's always been my good friend and do things together. Every night before bed he would clean me up, some time he washed me in shower but mostly he just use wet towel since I always take a shower in the morning, until I got pubic hair and he didn't say a thing. One night when I was 13 he did the same and I got a hard on so I ask him to stop doing this from now on. And I learned to masturbate a while after. I'm 18 and keep masturbating whenever I can till a month ago. I was doing it in the shower when I heard my father rushing and yelling into the bathroom that he got to pee and he couldn't hold it anymore. He entered the bathroom, I was stroking real fast with precum jizzing, he stopped dead seeing me, I too, stopped what I was doing in a shock. I covered my dick with my hand and tried to reach the towel and told him that it was fine if he had to go. Just then that I realized that it was too late, my dad already wet his pants. He was embarrassed, and I didn't know what to do but standing there with a soft dick in my hand till he broke the silence. He said (after he finished his business, gosh could you believe that, he finished in his pants, that he always know that I already did what I was doing but never got a chance to talk about it and now is a good chance but he had to get off his garments first. He dropped his pants first and took off his shirt then his white bikini which was now covered with yellow fluid. I ask him if he wanted me to turn around but he said no, to be fair he already saw mine and that now is my turn. That was the first time I saw his dick ever. I never knew that he's uncut, but I didn't have the nerve to stare so I just looked past it. He sat on the sink when he started asking me stuff like when did I start, where did I do it, on what I came etc. Then he stood up and revealed his cock to me, and also his muscular body (he works out a lot). Then I questioned him how's it is to be uncut and about his size. He told me it's 2.5" soft, now I'm 4", that's why I've never got to see it cuz I've always been big since a baby. Then he said that he thinks now I've beaten him already. I nodded. He told me to show him so I took my hand off and he said "cool! but I win with the hair", He's not hairy but since I'm kind of a clean boy he got much more than me. He told me before he left that from now on we could be naked around the house and I can take a good care of my cock anywhere and when "in the house". The next morning,Saturday, I woke up, put on my undies, and went to the kitchen. Dad already there naked having breakfast so I got mine. He then asked me if wouldn't I wanna get of my tighty whities also. I did. So I took them off and placed them on the table. He saw the stain and asked if it was urine or cum. I said I don't know maybe both since I had it on for 3 days. He was kinda shocked and told me that after breakfast we are going to go shop for underwear. We came home with plenty and various sort of underpants. Dad recommend that we should try them on, so we did. Then he went off for some sports and I stayed home doing things. On Sunday morning, I went to the kitchen naked and took some breakfast and since I'm naked alone and dad already allowed me to do it, I was playing with my cock and having breakfast at the same time. A while after, Dad came in to drink some water and said that he smelled something, so I showed him precum in my hand and he said that's it!! He walked over to see my now rock hard dick and comment on the size, so I just ask him to do the same so I could see his hardon. He said that he need to pee first then he turned over to the back yard window, opened it and peed right there. His pee went all over cuz he just let loose with out his hands holding it. After he finished his business and shook it he turned over start humping his cock and told me to stop and wait for him. When he was ready we faced each other and put our penis' together. Comparing my dick it had an "N curve" while his was straight so we got a ruler to do the job. I'm still bigger than him. He's 5.7" while I nearly touch 8. We keep stroking our cocks till I say  I gotta cum. He told me to step back to make our glans in the same level he just wanted to see who could shoot further. My first shot hit the side of the table and others just dripping out while later, he shoots across the table and into my cereal bowl. After catching our breath, we continued our breakfast and after that we just jacked off all over the place all day till our fluid run out and we did a couple of dry orgasm. After that we took care of the cum stains which was all over even on the TV screen. From that day we just go naked all the time, pee in the new place dad found, shower together and he would wash me like a little kid again and we would stroke our cock anywhere, anytime (in the morning or sometimes in the middle of the night) we want, together or alone (which happens more often). When we came home in the evening the place would smell of cum all around cuz we leave the stain and do the clean up on Sunday.
