Show me how a man fucks his dad, son

I was 15 years old, and had a huge crush on my dad. My dad and mom were divorced and I was an only child. He lived out in rural Missouri and didn't have a girlfriend or a companion at all. All he really had was me, and I was only at his house 3 days out of the week. I knew he had to get horny sometimes and I was waiting for the moment to capitalize on that.

I knew I've been gay for a long time, but none of my family knew, and I didn't want them to. The only ones who knew were a few of my closest friends. I was tall, slimmer and muscular. My dad was tall like me about 200 pounds, and very strong from working construction. 

I used to always gaze upon my dad, always being strong and sweaty. He would always take his shirt off and show his hairy chest. I would dream of his dick and him fucking me. But little did I know this dream was about to become reality. 

We were on vacation, something that only happens every 2 years or so. This time it was a cruise. I couldn't wait to be stuck in one of those small rooms with him for a week, I decided I would make a move during this. 

We just got on the ship and I was ready for the action to start. We got to the room and he said he was sweaty from the flight and was going to take a shower before we go to get something to eat. The room was just as small as I wanted it. There were two beds, a bathroom with just enough room to turn around. I was lying on the bed, and he got out of the shower, a towel wrapped around him and I was obviously looking at him, probably with my mouth open. The towel dropped in what seemed like slow motion. It revealed a approx. 7 inch, cut, rather bushy cock. I knew he saw me looking too, but I didn't care, I was just dreaming of it inside me. But unfortunately enough nothing happened this time. 

It was two nights later, we have just gotten back from dinner and he drank a little bit so he was a little loopy. I was laying on the bed when he came out of the bathroom and said to me, 

"Why've you been looking at my dick all this week?" I said back to him,

 "I'm just seeing what I'll be one day." 

He said, "You want a closer look?" With a smirk on his face. 

I said "Would I!" 

He walked over to me, he took off his jeans and shirt and was just in his tightly whities. I sat on the side of the bed and stripped down his briefs to reveal the beautiful dick I've come to love. 

He looked down at me, moving it around, and said "Like what you see?" 

"Yeah sure would like to know what it's like hard though" I replied. 

"Well that's no problem, just make it hard." He said slowly. "You know what to do, I've seen your search history." 

Given that my history was filled with gay men and gay sex, I knew exactly what he was talking about. I lifted up his dick and stared directly down the hole. This is the moment, I thought. The moment I've been waiting for for years. 

I let his dick hang and ran my tongue right up it, I could feel it pulse as I made contact. It was getting hard really fast. Once it was full I shoved it all in my mouth, it slid down my throat and I loved ever inch of it. I was thrusting myself back in forth. His dick was 9 inches hard, so I had to get some momentum going to get all the way down. This was the first dick I've ever sucked. I was going hard for a long time, starting to sweat as he grabbed the back of my head and pushed me all the way down. I could tell he was about to cum. He moaned loudly and I could feel the slime go down my throat. I swallowed it all. I took my mouth off and he bent over the bed. 

"What are you doing?" I asked. 

"I saw you getting out of the shower yesterday and I wanted to know what it's like to get fucked instead of fucking someone else so man up and fuck your dad!" He yelled back to me.

I said sure father and took off all of my clothes, until I was in my boxers. I told him to take them off and he did and squeezed my balls really hard, they hurt so bad I loved it. I was as hard as a rock so I spread his hairy cheeks apart and rammed my 7 inch cock up him. I heard him Yelp and I was thrusting back in forth inside him. I was so horny I came within 2 minutes. 

"That was weak son, I barely even felt anything!" 

I thrusted my dick very hard into him and was going really fast, my thighs hitting his ass making the cheeks red. 

"Now that's how a MAN fucks, son! Now put your clothes back on and don't be surprised if you feel your old man in the night." 

We fucked again the next night and when we got back home from vacation, the first thing I did was have him fuck me outside. Sometimes when I go over to see him I still give him blowjobs.
