So many stories! I'll start with a favourite:
My wifes friends birthday celebration had turned into a late night, which resulted in myself and my wife needing to get an expensive taxi to our hotel.
Some key points which will help you understand my mood in that moment:
1) My wife had made a mistake with the hotel booking, so our hotel was now a 30min drive instead of an 8 minute walk and she didn't realise this until we arrived at the wrong hotel....
2) We had agreed prior that we would be back at the hotel at a decent time so that we could get an early start (we had a 3hr drive to be at a very important meeting for both of us).
3) It was now 2:30am and our plans had gone out of the window. My wife is so drunk that she can't stand up on her own and I'm pissed because we need to be on the road by 9am at the very latest.
4) All this hassle and I don't even like this particular friend that much!
So we finally get into a taxi after being turned down by a few who don't want to drive that far. We're sat in the back as the driver heads out of the city center and my wife is insistent on making silly, drunk conversation. I'm tired and I've only had a few beers throughout the evening, so I'm barely even buzzed by this point. I just want to shower and sleep. My wasted wife isn't getting the memo though!
Ok, so now the scene is set for you. Here's what happened next:
Wife: "I know what will cheer you up

"
Me: *stares out the window, ignoring her*
Wife: "What if I sucked your dick? Would you be my friend then?

"
Me: "No. Be quiet. You're embarrassing yourself." (I'd be lying if I said that didn't cause a twitch in my pants though!)
Wife: "Lemme suck it and then you can say no for sure

"
Me: "Chill out babe. Let's talk when we get back to the hotel. ...... and I'm sure he doesn't want to see my dick in his mirror"
Before she could even reply the driver said "don't mind me... you do what you need to do...".
My wife and I look at each other a bit surprised and confused but her drunkenness evidently took over and she dived headfirst into my lap! She had my cock out in seconds and went crazy on me. It was an incredible blowjob and she performed it like we were in the privacy of our own bedroom.
My wife loves being degraded when she's drunk, so I started saying the things that really bring out her sub side and got her hair wrapped around my fist so that I could fuck her face and control when she came up for air.
9/10 times I would've cum quickly in that scenario. But the combination of me being tired, my zipper continually scraping me and slightly fearing for my life due to the driver not keeping his eyes on the road, kept my load at the "nearly there but not quite" point.
I started to recognise the area we were in and knew we weren't far, so I told my wife we'd better get decent as we were nearly back. She pulled off, seemingly annoyed that I hadn't cum but also understanding (I think she had slightly sobered up at this point too).
The taxi driver definitely killed whatever was left of the moment by spending the last few moments of the journey saying things like "I know somewhere we can go....." and "Do you guys want company tonight?". Like dude.... just enjoy the free show!
