I nipped round my mates house the other day for the usual catch up. I arrived at his flat as arranged and his missus answered the door prompt. We exchanged pleasantries and went in and she made me a drink while I sat chatting to my mate.


I have been out with him a couple of times in the past meeting women as he can pull women no problem while I have always been a bit shy and the girl he is with now has been with him for a few months and I think they will make a good couple.


Me and my mate have both been naked together before with women present and he asked me if I fancied watching him fucking his girl up the arse while I watched. He knew I love this sort of stuff so I was well in. She then appeared from the kitchen with my drink and placed it beside me.


She could see the bulge in my trousers so I reckon they had this planned as she was down to her t shirt and knickers ready and my mate took off what clothes he had left on. He is a very slim 20 year old with an 8 inch thick cock that looks straight up to heaven when full erect and an absolute massive bell end on it.


We have had wank sessions together in his flat and just watching his big bell end always gets me cumming first. This was going to be a real treat though seeing that huge bell end and thick 8 inch cock open up her bum hole and clean her ass tunnel out.


I sat and watched as she sucked his cock and got it sloppy wet ready for her anal insertion. She asked me to get the lube and lube her bum hole. I was shaking like a leaf as I touched her awesome anus that his beautiful big cock was about to penetrate.


Within minutes now they got in a position where I could view all that was going on as his massive member entered her anus and began to pump away. She farted as his big bell end pushed into her hole with all the lube in there and his thick shaft dissappeared into her Brown tunnel.


He didn't insert his full length straight away just a little at a time. It was several minutes before she was relaxed enough to allow her ass hole to swallow it all.


Once in balls deep they were both sweating like mad as he just kept fucking and fucking her ass. He pulled out. Her anal gape was huge and it was hot in there and the smell of anal sex was in the air.


I was rock hard and thinking hard as I watched him slip his cock head back into her dirty anal gape.


I plucked up the courage to ask if I could lick his cock. Straight away his missus said yes I wanna see that. So I moved closer and was really shaking now at the thought of this and knew it was going to happen. She was lying on her back with her legs up in the air and he was on top fucking her ass and I was now right there by his cock balls deep in her arse hole. He stopped fucking her and I took his cock and pulled it out of her ass hole slowly. Inch after inch came out and eventually his huge bell end appeared. It popped out of her ass hole and loads of goo followed out and ran down her ass crack.


His monster bell end was now at the mercy of my mouth. She could see through the gap between them both and I began to lick his bell end like an ice cream and it was beautiful. She had a huge smile on her face watching me licking his cock after she knew just how deep inside her ass it had been.


His cock head was sloppy wet with all her ass juices, his precum and the lube and I licked all around his bell end and ran my tongue up and down his full 8 inches. It was an awesome taste.


I held his cock tightly with one hand and gave her anal rose a quick lick before I put his bell end back towards her gape. Just in one hand I could feel the power of his mighty cock and the hard bone that runs the full massive length of it and wished it was me that was going to have the pleasure of fucking her ass hole with it. But all I could do was savour the moment as I watched his huge bell end and 8 inch cock slide back into her wet sloppy ass hole and she began to fart more and more as he increased his fucking rhythm right in front of my face.
