Although my wife fucked a couple of guys behind my back I never had any idea about it, however I did try to encourage her to fuck more cock than just mine. A few years before we split we started sharing our nude pictures on a very well know site. I never got much interest but my sexy young wife got loads which she lapped up.
Having had a few threesomes' myself I always wanted to see her fucked by another guy, but the answer was always NO!

That's until a young 23yo called Josh sent us a picture of his really good looking 9 inch cock, I made sure see took notice of how long and fat it was compared to mine and how deep it would go inside sexy big pussy. I kept working on her and eventually got them talking online. Every time they spoke I would fuck her and tell her how wet her pussy was and how obvious it was that she wanted that big cock inside her.
Eventually she agreed she would fuck him one time only as a 40th birthday present to me. (I now think it's because she felt guilty about fucking a guy called Lionel she knew) My wife was 9 years younger than me and hot as fuck in sexy underwear so I knew it was going to be a good show.
The ground rules were simple they would fuck in a hotel I would watch and not interfere no picture and no videos at all.

The night finally came and Fran dressed in her sexy black underwear, 1/4 cup bra crutch less knickers stockings and suspenders, over the top she wore a long black summer dress that buttoned all the way at the front.
We all met up in a pub and had a couple of drinks to settle all our nerves and give Fran one last chance to back out, my cock was getting hard just looking at them talking to each other. Soon we were ready and headed off to the hotel.
I walked into the room first and sat on the sofa with a bottle of wine and a glass I had brought and got settled ready for the show.

I watched mesmerised as they kissed, Josh undid Fran's dress and it dropped to the floor revealing her full sexiness, she in turn removed first his shirt then undoing his belt and pulling his trousers and boxers down to the ground. I got my first glimpse as Josh's cock and it looked even bigger than it did in his pictures. Fran then pushed Josh onto the bed removed his shoes socks trousers and boxers leaving him completely naked as she began to suck his cock, she had a full fist of cock in he left hand and what was poking out the top was still more than I had ever fucked her with!

I looked at my wife's beautiful arse as she sucked another man's cock and removed my trainers and trousers and started wanking my small hard 5 inch cock. After a while Fran got Josh to lay in the middle of the bed I watched as she straddled him wet her pussy with her fingers as she had done me so many time then watched as she lowered her pussy onto Josh's massive cock. Inch by inch it disappeared inside her until she had his hole length inside her.

Fran slowly started rocking backwards and forward on Josh's cock before she started lifting up and fucking him rhythmically, as her cunt went up and down his long shaft I could see it getting covered in her thick white pussy discharge, it was too much for me and I cam all over the hotel floor. As I relaxed watching them with my now soft cock in hand they changed position, I watched as my wife lay there with her legs wide open as Josh climbed between them and push his massive cock back into my wife again. Fran reached between her legs and started playing with her clit as she was fucked twice as deep as I had ever fucked her and it wasn't long before she balled her fist in the duvet and moaned loudly as her orgasm ripped through her. Josh just carried on fucking her till she had finished then asked her to get on all fours for him.

I sat there as my slut wife in her finest lingerie got on all fours her breast hang down as her lover knelt behind her with his big cock rubbing it up and down pussy lips before once again sliding inside her. He started off quite slow and gentle but as he got harder and faster I could see his huge cock was hurting Fran, a couple of times her hand shoot and stopped him as she cried " too deep, too deep, too deep". Eventually she put her hand and two fingers ever side of his cock to buffer it as he grabbed her arse and started to slam into her, even with an inch less she still went "OW" each time he fucked her deep and smashed her cervix till eventually he pushed right inside her making her scream as her let loose his young virile cum.

I know I said I wouldn't interfere but I couldn't help it, as Josh pulled out I cupped my hand under Fran's pussy catching the sperm as it ran out then started licking her clean and believe me there was a lot of it, as I was cleaning her Fran rolled on her back making it easier for me to collect all Josh's cum as she held onto the back of my head.
After I Had finished feasting on Fran's cunt I assume Josh would go home so was quite surprised when Fran joined Josh in the bathroom and locked the door. I heard the shower go and 5 minutes later Fran and Josh came out the shower both naked. Josh go into the double bed while Fran grabbed 2 pillows and the spare Duvet and threw them on the couch " Happy birthday Baby" she said then Joined Josh in bed before turning the light off.
At first I played along thinking it was a joke but it was apparent it wasn't as I heard them clearly start fucking again. All night I listened to them fucking, Josh telling her how sexy she was and her Praising his cock all night saying how good he was compared to my perfetic little cock. I don't know how many times he fucked her that night, at least twice judging by the number of times she went to the toilet. As for me I only managed to pull myself off once more as I couldn't get hard again after that.

In the Morning we all went home my wife wouldn't even let me see her naked for a week let alone touch her saying she was to sore! And when I did eventually get to fuck her she just lay there like a blow up doll uninterested ? Thankfully things got back to normal about six months later ! (she was probably fucking some one else!
