My first time getting a big cock in my ass

I got talking with a relatively local guy, much older than us, but had a thick 8.5" uncut cock, which was perfect for what I wanted to watch enter my Mrs.

Our messages went something like this...

Me "Did you want to meet up first?"
Him "If you want"
Me "We'll chat about a plan, then I'll bring you over to introduce you"
Him "Let's meet up at your place?"
Me "Prefer not at first"
Him "No deal then"
Me "Okay then, our place"
Him "I take it you'll want to see my cock, and make sure it's as big as I say it is?"
Me "Only if you want to"
Him "Address, and when?"

I gave him my address, and told him that I'm home alone now, until 6pm (it was about 9am).

Him "See you in 20"

He was about 8 minutes late, but I met him at the front door.

Me "Hi...come in" opening the door.

After chatting a few minutes of small talk, he stood up and pulled down his tracksuit pants, removing them and throwing them on the floor.

He was standing in front of me, with a cock as big as he said on messenger.

Me "Nice"
Him "You really want me to fuck your wife"
Me "Yeah"
Him "Get your clothes off"
Me "Na, it's alright"
Him "I wanna see what she's used to"

I removed all of my clothes, standing there flaccid.

Him "Come here and suck my cock"
Me "I'm not sure..."
Him "If you don't, I'm not fucking your wife"

I went over and dropped to one knee, taking his cock in my left hand. I played with it for a few seconds...

Him "Don't be shy"

I opened my mouth and started sucking the head of it.

Him "Get it in there"

I gagged as I tried, then stopped as I watched him getting hard.

Him "Do it again...only better"

I tried again, but kept gagging and stopping.

Him "Come on, get up"

He helped me up...

Him "Go bend over the kitchen bench. I'm going to fuck that arse"
Me "No mate, please"
Him "You want your Mrs to feel it, then so are you. Now do it"

I reluctantly bend over the bench and grabbed the other side.
