My Dad and I used to fuck around. Yeah, my real Dad. But I thought we had moved past it, until he fucked me again over Christmas this year.
It all started when I was younger and Mom went back to work full time In the evenings. Evidently this put a real crimp in my father's sex life, and so I ended up filling in. I mean, I had heard my parents having sex. A lot. My room was right next to theirs and sometimes they weren't quiet. You see, when I was growing-up, my family was very hippie liberal. Lots of nudity. Sex was discussed from an early age. I took occasional baths with my father, or sat and kept him company while he bathed. I also knew about his porn collection and would often sneak viewings of it after school. There were a lot of Playboy magazines, but also some real hard core stuff. Anyway, when Mom went back to work, Dad started masturbating in the evenings. I know as much because I could hear the porn videos and the faint squeaking of his bed. He also almost never closed his door all the way. Being curious, and a bit twisted I guess, I started sneaking out into the hallway and watching him. It was strangely erotic watching my own father masturbate and shoot his load. Erotic, but also shameful. I knew it was wrong, but I still got hard.
Eventually he caught me spying. I figured he was going to go apeshit, but all he did was call me into his bedroom. "You might as well get comfortable and have a wank too," he told me. That's how it started. Every night we would watch porn and jack off together. But then one night he put his hands behind his head and told me he was tired and I should jack him off. And I did. His cock was heavy and thick in my hand. He came quickly and it ran down my hand. I was excited by and ashamed of what I had just done. But I didn't stop. Soon after it was "You know, I could sure go for a blowjob like in the videos." And again, I gave him what he wanted.
I had already experimented by having given blowjobs to my cousin and my best friend and a couple of other guys, so I was good at it. Apparently my Dad noticed my skill and appreciated the fact. I still remember the first time I blew him and being rewarded with a mouthful of his saltiness, and the compliment "Damn, you're good at that!"
After that I was his cock sucker. We rarely talked-- just got naked, watched the porn, and I would blow him. The whole time I was fairly conflicted about the arrangement. Here I was, horny, getting sex almost every night (when I didn't have late school functions or excessive homework). But the sex was with my Dad. Within a year or two, we transitioned to fucking. I don't really remember what prompted the change, but one night just as I was getting into sucking him he pulled me off saying "I wanna try something different tonight."
With the porn playing, Dad had me get on all fours. He got out a tube of KY, smeared some on my hole, some more on his cock, and then started to push his dick into me. It hurt. A lot. It took a few tries and a lot more KY, but he managed to get all the way inside me. "Damn you are TIGHT!" I remember him saying. And then he started humping me.
For me, this was a lot different than the blowjobs. Sucking Dad's dick was much less of a transgression in my eyes. I was just helping him masturbate with my mouth or something. But now I was being fucked, and that just seemed wrong. It was uncomfortable. It was degrading. It was something that a wife (my Mom) should be for-- not me. I was suddenly ashamed and embarassed that I was in my parents' bed, letting my Dad have his way with my ass. I zoned out watching the big-titted woman on the video getting butt fucked as well. I remember wondering of she actually enjoyed it or not. Then Dad tensed up, an I knew he was cumming inside my ass. I also noticed that the fucking left me rock hard. While my father cleaned up, I jacked off, full of hot shame.
We fucked a lot after that, not a lot of talking. And always from behind.
Eventually I moved out of my parents' house. After that, divorces, jobs, his new girlfriends and marriages kept me safe from any repeat sessions.
Until this past Christmas.
He came to visit me for a couple days, alone. His newest girlfriend had to work so she couldn't make the trip. To be honest, the thought of us having sex again hadn't really even crossed my mind. I had come to terms with what we had done, and realized that he was probably responsible for my fetish for older 'daddies', but that was it. Besides, my Dad was around 60 by this time. Well, evidently the men in my family are always horny bastards.
We had been drinking and watching football games when it was time for bed. I got him set up in his room and retired to mine. It felt like I had just fallen asleep when suddenly I felt him. It really startled me! "Dad, what the fuck are you doing?" I exclaimed.
"I think you know" he said.
And I did. I could already feel his erection pressing against my ass. Dad wanted sex, and as much as my adult self was repulsed by the idea (and truth be told, with him, at least at that moment), I knew I would relent. I would again give up my ass to Dad, even after all this time.
I pulled off my boxers and started digging in my night stand for the necessary stuff. I lubed up my ass, then reached back and lubed up my father's cock. It was thick and heavy in my hand. And familiar. So much like my own cock now. I assumed the position, and took a hit of poppers. "Son, are those drugs?" he asked.
"No, Dad, they're just poppers. They help me relax."
Hrmph was all he said as he thrust into me. So many thoughts and feelings swirled in my mind while Dad used my ass for his pleasure. I was ashamed for what I was doing, of what I was allowing him to do, and also ashamed that my cock was hard and that the sensation of Dad's cock sliding in and out of me was such a turn on.
It didn't take him long before he was wheezing and squirting his load into me, donating his sperm and his DNA as he had done decades earlier in creating me.
When he was done, he pulled out and slunk back to his room for the night. And I was left to jack off in hot shame, turned on like the bottom cum whore that I am. The bottom cum whore that Dad had made.
