It was Friday afternoon, I'd got home from work early. Knowing no one would be home for a few hours I decided to have some me time.

So I got undressed and found some porn to watch; I put it up on the big screen and got my favourite lube, sat back in my armchair, and started messaging lube into my limp cock.

The movie had got underway. I sat and watched as a group of people were making out and undressing each other. With the massaging and film, my cock soon became hard.

As the group on TV were kissing, sucking and licking, I started running my fingers over my veiny hard shaft, this made my cock twitch. It felt so good.

I was really enjoying my hand on my cock while watching and listening to the people on the screen when suddenly the front room door flew open I looked up, trying to cover my cock.

I saw my neighbour Mark standing there.

"Sorry, mate, I didn't know you were busy. Your back door was open. I did call out, but I guess you had more important things on your mind."

I could feel myself blushing.

"Don't be embarrassed; we all do it. Come to think of it, I could really enjoy one myself. Do you mind if I join you?"

I was shocked, I didn't think he was going to say that. Still a little red and in shock I nodded my head and said,

"Make yourself comfortable."

As I sat there with a cushion over my cock, Mark pulled his T-shirt off and dropped his trousers and stood in front of me in his white Y-Fronts. He looked good for a man in his seventies.

Mark said,

"Shell we show each other our cocks after three? One two three."

With that, he put his thumbs in his Y-Fronts and pulled them down revealing his fat six-inch limp cock. At the same time, I take away the cushion to show him my six-inch rock hard-cock. I couldn't take my eyes off him or more to the point, his lovely cock.

As he sat opposite me, the first thing I noticed was that he was cut, the first one I'd seen. I threw him the lube and said,

"Wow, your wife wasn't lying you are big."

He smiles and squirts a big blob of lube on his helmet and starts rubbing it all over his huge cock. Almost as soon as he started, his cock grew to around ten inches I couldn't believe my eyes.
I sat watching him grow, one hand at the base of his shaft, the other stroking his full length. He looked over at me and said,

"We're meant to be doing this together."

So I start stroking at the same pace as him. I could hear the soundtrack of the porn but my eyes never left Mark and his monster cock.

My cock felt amazing between my fingers as I slowly wanked. But all I was thinking was what would Mark's monster feel like. With that, like he had read my mind, he said,

"Would you like to come and feel me?"

Without saying anything, I went over to the sofa and sat next to him. I put out my hand and grabbed his cock. My fingers barely reached around it. With no foreskin to pull, I gripped it tight and started stoking up and down his long shaft. It was then I felt his hand on my cock, which made me excited, and I picked up my pace on his cock, making him moan.

His hand felt really good on my cock but he was just holding me. I start stroking faster and squeezing a little tighter. I could feel his pre cum run out of his helmet, his breathing was getting heavier, and he was moaning a lot louder.

He slowly pulls on my cock, as I'm getting into wanking such a large cock. Mark looked at me and said,

"Slow down, or you're going to make me cum."

But I didn't listen to him, wanking him faster with my hand tight around his fat stiffness. He squeezed my cock really hard and shouts,

"Fuck Fuck Fuck."

A long string of cum shoots from the eye of his cock and lands on his belly. Then there was a gush of thick cum, running down his cock and over my fingers. I keep wanking as more and more cum covers my fingers.

"Was that good?" I asked.

He nodded and got to his knees in front of me, puts his head between my legs and took my cock in his mouth.

"Fuck what are you doing? That feels amazing, don't stop."

I put my cum covered hand on his head and pushed my cock deep into his willing mouth. It didn't take long before I started shooting into his mouth. To my surprise, he swallowed the lot and then fell back to the floor, and said,

"I only popped in for a coffee. What a lovely treat."

He then started to laugh, I looked down at him laughing and saw his big cock giggling about.
I get up and get dressed and go and make the coffee. When I returned, Mark was just tucking his cock away. He looked at me and said,

"Cheers for the coffee. Maybe we could invite our wives next time."
