My mom's stepbrother Greg is one of the hottest men i've ever seen. I'm 22, and "Uncle" Greg is about 42 or so. He's redheaded, originally from Australia, and he's really friendly and masculine and so damn handsome.

I was home from grad school for Thanksgiving, and Uncle Greg was visiting from one of his adventures down in South America (he's a marine biologist, as well as a champion tri-athlete).

Thanksgiving night my family went out to a movie, but Uncle Greg said that his thigh was killing him since he pulled it running last week. He needed to stay in. I told the family I wanted to stay in, too, that I could keep Uncle Greg company and help clean up. They were all okay with that and said they would see us when they got back. None of them suspected what I was up to. I wanted Uncle Greg's monster cock in my mouth. Now, I didn't know if it was monster, but I had seen the bulge in his pants between those massive tree trunk thighs of his. He made me so fucking horny I couldn't stand it. I know he was straight, but I didn't care.

"You want me to rub your thigh, Uncle Greg?" I asked him after we both had two more beers each.

"Aw, mate, that would be FANtastic," he said back. "Let me take a hot shower first."

I brought him a towel and watched through the crack in the bathroom door my gorgeous uncle strip down to nothing. He had strawberry blonde chest hair and leg hair. His body was so manly and rugged, with two big pectoral muscles and big chewable nipples. I wondered if he knew how sexy he was. When his briefs came off I got a glimpse of his incredible asscheeks. My dick grew ten times its size just seeing that hot white ass with the sweat beads on it from the shower steam.

He came out of the shower and lay down on the bed, and I reached under his towel and massaged his tight rock-hard thigh. I was getting so hard. My hands found their way onto his beautiful assmeat, and I lovingly guided my hand deep into his asscrack as he moaned.

"Is this okay?" I asked nervously.

"Oh yeah, mate," he said, and then he rose from the bed, grabbed my face and kissed me hard on the mouth. In that moment I knew I had always been in love with my uncle, and I wanted to be whatever he wanted me to be. Our tongues collided with each other as he stripped me naked. He took my underwear and wrapped them around my eyes to make a blindfold. Then he stood in front of me and I could sniff the smell of cock right in front of my face.

"You want this?" he asked me. "Do you want to taste my meat?"

"Yes, Uncle Greg," I said.

"You'll make love to my cock?" he asked.

"Yes," I said, and then I felt it being shoved into my mouth. My head went hot as the crushing force of his manly cock dug deep into my throat. My face was being pushed out like a balloon as it got stuffed with his veiny, silky dick. I was going out of my mind with young lust.

He took the blindfold off so that I could see his strawberry blonde pubic hair right in front of my face. I could feel his big slippery balls right underneath my chin as I gagged on that humungous dick -- I was right, it was a monster.

Uncle Greg pulled me up onto the bed and positioned me so that my ass was spread out for him and I was lying face down on the bed. His face dove into my gaping asshole -- I had never felt anything like it in my life. I felt so exposed and vulnerable.

"Oh!" I shouted as his finger entered my hole. He kissed the back of my neck and rubbed my back, relaxing me so that my ass-snatch would accept his finger. Then he added another finger, then another, so that three of his big fingers were excavating the inside of my moist ass. Sweat poured down my face. I closed my eyes tight, feeling the penetration of my Uncle's hands into my tight young ass. It was so fucking hot.

"Fuck me, Uncle Greg!" I whispered aloud, and that's when I sensed him reaching into his jeans for a condom and slipping it on. He spat on his dick many times and then I felt a surge of pain between my asscheeks as his cock banged up into me. First his fat mushroom head invaded me, and then came the rest of his shaft. I could barely breathe the experience was so intense. But then it got easier to accept. He felt so much bigger than me, like I was going to break under all that massive weight and strength. "Oh yeah..." I moaned as I grabbed my dick and started jacking off, raising my ass higher so as to take more of his shaft in. He gently pumped his prick into me deeper and deeper, so that our two bodies were becoming one.

I felt the lips around the edge of my asshole contract as he pulled out and then thrust in again. I felt his hands cupping my pecs as he mounted me and fucked me like a lion in the jungle. He pumped harder and faster and I could feel his dick growing inside me, filling up with cum about to shoot. He pulled out and ripped off the condom and suddenly I felt hot droplets of cum fall onto my back. "Oh, FUUUUUCK" he cried out as more and more gobs of cum fell onto my back like spilled hot batter. I turned myself over and then I sat on top of my uncle, jacking myself off as he watched. I kissed him as my own cum shot out of me like a geyser.

We lay there together, and then we showered. My family came back from the movie later and they had no idea that I had just fucked my uncle.

I can't wait till next Thanksgiving.
