WiganDaveHi Bxtreme, I've been in the place where you are now. x
I agree with ionsawmill - suggest an idea & let it grow (but tactfully mention the idea from time to time to help it grow).
Sorry, but I've just reviewed my story & it's a long one, hope you don't mind :-
In the mid 1980's (when we were both in our mid 40's) my wife was the same as yours. I had Cuckhold fantasies, but she was straight - until I started saying things to her like "Gary keeps looking at you - have you annoyed him?" when we were in the pub after work. Gary was one of the 4 Hunks in her team - you could say that all 4 were 'under her' !
"Really? - no I haven't". She was flushed as she said this. I encouraged her to have more pub drinks after work on Fridays. "Pay for the drinks for your team - it's team building" - "Really - ok then"
"Leave the car at home this Friday. I'll drive you to the railway station. After work, I'll meet you in the pub to join you & the Team, then I'll drive us both home. I made a point of arriving at the pub later than the others. Each time, Helen was tipsy when I arrived. I suggested things to Gary (and Dave, Darren & Bill - the other 3 in her team) like "thanks, lads for looking after her. She has a boring life at home with me - it's only her work & the office banter that excites her" I saw the look on their faces when I uttered the word "excites". It didn't take long for Helen to ask me to leave it a little later before I picked her up on a Friday.
The following Friday I purposely arrived even later than she suggested - but I didn't enter straight away. I went to a side door & was about to enter when I stood on a crate & looked through the window. Dave & Bill were leaning on the bar, looking inwards. Helen was sat with her legs apart & Gary & Darren were both fingering her ! She looked to be in paradise. What should I do ? I was turned on, but I didn't want to ruin the atmosphere. I went into the other bar & bought a small drink (I was driving) then gradually moved towards them. Dave & Bill saw me & looked shocked "It's ok, boys - she needs some excitement in her life. Don't tell her, but I want to watch the 4 of you fuck her". I gave them £20 & said "buy her a few more drinks, then come and into the other bar & tell me when she's ready ". 1/2hr later I was summoned. "Hi Helen - having fun with your team? You lot work very hard, so it's good to let off steam occasionally. I've just promised the lads a lift home - you don't mind do you?" She beamed at this suggestion. Downing their drinks I shouted "All Aboard. Only room for 3 in the back" at which point Gary got in one side as Darren pushed Helen in & sat beside her. Bill & Dave had to squeeze into the front passenger seat - looking a little disgruntled. After a couple of hundred yards Helen slurred "Derek, darling, where are you going? this isn't the way home, this is the Company car park" "I know darling, but I need a pee" so got out to pee. When I got back in both Gary & Darren had their fingers in Helen's cunt & her hands were on their erect cocks. I smiled at her & she smiled back - the barriers had now been broken. As it was a warm summer evening, I encouraged the 4 to fuck her on the bonnet of our car (no stains on the seats !) They did so & she enjoyed it. I kissed her deeply throughout her fucking. "I think they're ready again, Baby" I whispered to her. She looked shocked "they're only 25yrs old - they can go all night !" They fucked her again on the car bonnet - Missionary & Doggie (I had a hard-on watching). I drove all 4 home & then we returned home. We had only just got inside the front door when Helen dragged me to her & French kissed me. "Thank you darling for tonight - it was wonderful" - did she suspect that I had arranged it all? No matter, we went upstairs to bed. "Fuck me. Fuck me hard" she demanded as she lay on the bed. I lifted her dress. No underwear (knickers & bra lost in the company car park, no doubt). Always, before we had penetrative sex, we would give each other oral. I thought "she's been fucked 8 times tonight, I'm going to have to give her a lot of oral to get her interested so I went down on her (momentarily forgetting that she'd received 8 loads of Cum !). I licked her labia & sucked her clit & I loved the smooth salty taste to her (I never thought that this change in her juices was the spunk inside her). Despite being fucked 8 times, she responded to me & I then fucked her frenetically - it didn't take me long to Cum - I'm not sure that she did
The following morning Helen & I had a long chat about this. The outcome was positive for both of us & we had numerous sexual encounters afterwards.
I do hope that my experience can help you - please let me know how you get on - genuinely (I'll give you my personal email address if you like).
