Unexpected foursome

My wife and I went to stop at our mate's house and his dad, who we also know very well was staying over as well, he is nearly eighty and a great laugh and is always passing comments about how sexy my wife looks and how he envies me being with her.

We stayed in for the night playing cards and having a drink or two, it must of been around midnight when my wife and his dad said that they were tired and did they mind if they went up and left us two chatting. This is where our story splits in two for a while before rejoining later. My wife's version first:

I was getting undressed in the bedroom when I heard our mate's dad coming up stairs and then his foot steps stopped and it was then I noticed that I had not closed the bedroom door properly and I could just see his dad peeking in. I was in just my bra and knickers at this stage and it felt nice to know another man was watching me undress, so I turned towards the door as I removed my bra so that he would see my tits in all their glory, I then turned away from him to remove my knickers, bending right over so he could see my ass and a peek of my shaven pussy. I glanced at the doorway and he looked to be wanking his cock, my pussy went really wet and then he went into his bedroom. I don't know why but decided to follow him, he was in his room, totally naked with his back to me. He was quite slim but his skin was wrinkly with age but yet muscular. There was a big mirror opposite him and one part of him was definately not wrinkly! He had an enormous cock it must have been about 11 or 12 inches long and really thick, apart from pictures I have never seen a cock so big. My nipples went hard and my pussy was now dripping wet, to be honest I did'nt know what to do, I heard noises from downstairs from my hubby and our mate, I went down the stairs a couple of steps so I could see them in the living room, they were watching a porno movie (as usual) and they were wanking each others cocks, I watched them for a while thinking what I could do with them two cocks but yet again neither of them were as big as his dad's cock! So I went back to his dad's bedroom door or that was my intention, instead I walked straight in, he was still wanking that enormous cock! I grabbed hold of his cock it filled both my hands and I could only just get his bell end in my mouth, I wanted this big cock inside me, now! I got on the bed on all fours and he started to force the monster into my pussy as he pushed it further in and then started to shag me it felt fucking great and stretched my pussy to its limits...

Now my story:
My wife had gone to her bedroom and my mate's dad to his so we decided to watch some porn movies after a while we both got our cocks out and began to wank while watching the goings on in the movies, we were both on the settee so close to each other and my mate moved his hand and by accident touched my balls and obviously he liked the feel of my shaven balls and I liked him touching them so I did likewise and before long we were both wanking each other off at this point I thought I noticed someone at the top of the stairs but was enjoying myself too much to look again and the thought that it might be my wife and that she might come and join us so that we could both fuck her did cross my mind. Before long we were both on the floor doing a 69 and sucking each others cocks, I and I am sure my mate had never done this before but it was a great experience. We stopped before we wanted to cum and I suggested we go upstairs and see if my wife would let us both get into bed with her and he agreed as long as we did'nt disturb his dad, as he needed his sleep.
And so both versions become one.........................

As we climbed the stairs we heard noises coming from his dad's room, we both almost ran to the door to see if he was alright, ALRIGHT!! He was fucking the arse off my wife, he had her doggy style on the bed and was giving her a good fucking and WOW I just saw the size of his cock, no wonder she was smiling so much while he was shagging her. I pushed my mate onto the bed in front of her and she instantly grabbed his cock and engulfed his hard shaft in her mouth, she beckoned me around the bed and then she wanked my cock while I watched her suck my mate's cock and get shagged by his dad with his enormous, thick cock. His dad bucked as he pumped my wife's pussy full of his spunk and his still big cock slid out of her dripping pussy, she turned around and my mate rammed his cock into her as she took my cock into her mouth, my mate fucked her hard until he also filled with his spunk and she turned again pushing her arse out towards me, her shaven pussy was shining wet and almost glowing red with streams of my mate's and his dad's spunk running out of her. My cock was rock hard erect I pushed into her cum filled pussy, their spunk squeezing along my hard shaft as I thrust my cock deep into her and flowing over my balls. I shagged this cock happy wet, soggy, hot pussy until I too shot my load of spunk deep inside her. All four of us collapsed on the bed absolutely exhausted. I had to help my wife back to our bedroom she was so knackered the spunk from all three of us was dripping from her filled pussy onto the carpet as we walked. We both agreed it had been a great night my wife said it had been great all three of us fucking her and our mate's big cock was unbelievable!! But it took her a few days to recover!
