My wife wanted me to go to a party at our club. I only belong to use the facilities, generally I find the people there boring as hell, the guys talk only about their hunting trips, golf games and tell 'dirty' jokes I heard in the 5th grade. I said I'd go for an hour but she had to give me a BJ in the parking lot after.

Car
 

In the car but not just in the car. Try driving in downtown and getting a blow job when it was busy.

Toni blew me in her mother's bedroom last weekend.

Close call
 

About 7 AM in a training classroom located in a mostly unused warehouse. My secretary was helping me prepare to teach a class that day. We were almost caught by a customer who showed up early.

Pre-op before going into surgery.
Nurse walked in on us.

A few years back when on holiday with another family in Scotland, the two guys decided to hire kilts for an evening out with just our wives. As you'd expect, there was a lot of banter about what we were wearing underneath, etc.

For some reason, my wife has few inhibitions in front of these particular friends. Even so, I was still a little taken aback by a suggestion she made that evening. She said she intended to give me a blow job after dinner in a shop doorway on the main street.

The other lady said she never sucks her husband's cock. We expressed surprise as she's no prude and felt sympathy for her husband. I wasn't sure if I should suggest my wife perform the service for him instead as his need was probably greater than mine.

His wife tends to falter after drinking alcohol, so we jumped straight into a convenient taxi outside the restaurant. Therefore, we didn't walk past the doorways that my wife had in mind to do the deed.

Once we'd checked the kids were OK, our friends sat down to watch TV. We told them we had some unfinished business and popped outside where there was an alleyway between two of the cottages in the holiday complex. My wife got down on her knees, lifted up my kilt and did exactly what she promised.

It wasn't quite as exciting as doing it in the centre of town with our two friends watching as originally planned but satisfying all the same.

We were away on a golf weekend, condo we rented was right on the 12th green. We go out late after midnight and naked putt with the other couple we were with. then the girls would blow the winner.

I worked with a promiscuous gal at a restaurant. On weekday mornings there were just two of us wary for prep. When it was just her and I, the conversations would sometime get sexual. She was very outgoing and open. One morning I recall being half drunk from the night before. With that liquid courage bubbling before the surface I exclaimed “I bet you can suck a good dick”. She smiled and said “you know it. Maybe you’ll get to experience it sometime”. So I said “now’s as good a time as any”. Before I knew it we were in the walk in cooler with my pants around my knees. She probably took 25 loads of mine in her mouth in there during the six or so months we worked together. Never did fuck her though.

Two
 

Two that come to mind right away...
A g/f once gave me a nice BJ one Halloween night on the headstone of a well known "vampire" grave here in New England. The other was while sitting on the swing set of the elementary school I attended years before. Of the two, I'd choose the playground swing again because A) October 31st is cold here in N.E. and B) the playground situation didn't end with just the BJ, lol.

So did you win? Not that you could ever lose. I might be willing to miss a putt to watch my wife suck my friend to completion.
