So for years (and years!) I’ve wanted my wife to sleep with other men, she’s always flatly refused although she enjoys the games and has always gone along with the role play in the bedroom when I describe her being fucked by a bull whilst I tell her what a dirty horny sexy cheating unfaithful slut she is.

So back at the beginning of 2019 my wife decided to lose some (4st!) weight by joining a gym that did HIT classes, initially very nervous, she soon came to enjoy them and as the weight came off her confidence shot up. She’d often talk about the instructors as they kept up a good rapport with the gym members and (serious for a moment) they where the single biggest thing that kept her going through the initial weeks, until she found her gym legs.

Over time her gym stories focussed on one in particular (lets call him Pete) so I started to bring Pete into our bedroom role play, which really seemed to turn her on. Pete is only a few years younger than us (we’re 49yo) an ex-Army PT who is still in good shape as a result of his job.

At the end of ‘19 she booked onto the gym Xmas party (in the hotel where the gym was) she asked if I wanted to go, but sniffing an opportunity I said no, I was very honest telling her she could play the field with Pete and see what happened.

In the weeks leading up to the party my mind was in over drive and I would take every opportunity to fuck her while telling her to pretend I was Pete, we where both loving the sex.

I helped her pick her dress, short(ish - sigh!) with lots of cleavage, insisted she wore hold up stockings and some sexy heels, on the night of the party I nearly kept her at home all to myself she looked so damn hot!

Before she went I told her again that if something happened with Pete, she should go with the flow and see where it led, and if she fucked him I wanted sloppy seconds, whilst not an outright no, she just said ‘stop being silly’ smiled and got in the taxi.

So after a few hours alone with my cock and the cuckold videos on Xhmstr I got a message about 11:45 ‘are you sure about this?’ Well that got my notice! I messaged back saying ‘YES!!!!’ with lots of hearts and kisses, followed by a pic of my rock hard cock saying ‘this is me thinking of you being fucked’, she just said ‘I love you, see you in a bit’

About 1am I took myself off to bed then shortly after I heard the front door and the sound of unsteady feet coming up the stairs. She had a bit of a sway on, carrying her shoes and her hair was a mess. Whilst she undressed i started to ask loads of questions, she just shushed me, kissed me and climbed on my rock hard cock.

First thought? She has no knickers on (result - the crowd goes wild!) second thought? Wow, wow, wow she was so wet and slippy she must have been fucked. She rode me furiously until we both came (it didn't take long!)

After that she just kissed me on the lips, smiled, rolled off and went to sleep.

So the post mortem the following morning was - No it wasn't Pete! (WTF) It was another of the actual gym members (Mark), he’d sat next to my wife, kept her laughing and giggling all evening, danced with her and then started rubbing her leg with his, plied her with drink, damced some more, started groping her stocking tops and then just asked her if she fancied going back to his, she said initially she’d laughed and said no but then he grabbed her for one of the slow dances and just ground his hard cock into her whilst kissing her neck and whispering in her ear begging her to come back with him, she said she felt so horny and wanted to do it so that was when she messaged me.

So we spent the rest of the day in bed whilst I fucked her and got her to tell me ALL the details, yes he has a bigger cock than me (result!) but not the porn star cock that fucks her in my dreams, he made her cum ‘big time’ (her words) and he didnt use a condom - wasn't even discussed. That day and every time since when I mention Mark (and I do A LOT) when we are fucking it sends us both into overdrive. I’ve even had to pause writing this because it made me sooooo horny!

She was a bit nervous about seeing him at the gym, but the first time she said he just smiled and was cool and didn't make a big deal.

So here we are 2 years later, she’s kept the weight off (plus a bit more) even through lockdown, and on the 16th of December its finally time for another gym class Xmas party - I’ve chosen her dress (properly short this time!!) and I’m hard every day just thinking of the possibilities…..
