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.

Circumstances
 

Brother-in-Law and Wife had just returned from Overseas, so since I was in the vicinity of their temporary Apartment I called in. He was out, expected back later. Knackered from my journey, I crashed-out in their spare bedroom, away from their 2 squarking toddlers. Then, I'm rudely awakened by the sound of a vacuum cleaner. As I stir, she twists the hose under the door handle and turns towards me. Heaving back the coverlet, she kneels by the bed and unzips my trousers. I swing my legs over her head as she loosens my waist-band and pulls my Y-Fronts down. "AH" ! she exclaims, "what a whopper! I've seen longer, but not wider"! She rolls back my foreskin, kissing my purple helmet as I rip open her blouse and lever her tits free of her bra. I reach up and grab her by the ears, pulling her head down onto my now rampant cock. She takes the full length, and girth, with consummate ease. I viciously maul her tits. She gaggs as I pinch her nipples, keeping time with her nodding skull. Suddenly, the door is kicked open, Hubby standing there viewing the scene. She leaps up, swiftly gathering her blouse as they exit together. I rise, standing behind the curtain to finish off with a quick nifty-fifty in the window, overlooking the gaggle of mothers Parking-Up from the School Run.

in my office
 

For a while I worked in an office with 7 employees. My office was located at the end of the hallway from the rest of the staff. My office has a big window so I can see anyone coming down the hallway.
One day one of the ladies, M, came to my office an stood in from of my desk. I looked her up and down then my eyes fixed on her large boobs tucked inside her bra and tight blouse. She knew I was staring at her tits and she commented "I bet you want to feel my D cup breasts". Well I reached across my desk and squeezed her tits. She then came around my desk, got down on her knees and unzipped my pants. She pulled out my cock and went to town on it. I noticed on of the other ladies coming down the hallway towards my office so I told M someone was coming. Instead of getting up from my desk, she hid under it and continued sucking my cock. The other lady asked me a work related question which I began answering. Answering was quite difficult as she was about to make me shoot my load and I was sweating. The lady asked if I was okay. I asked her to give me 15 minutes and I would come see her when I felt better.
M finished me off with my load in her mouth. She asked if the coast was clear which I said it was. She got out from under the desk, showed me my load in her mouth and said anytime I needed it I could just ring her up.
I switched positions about 2 months later but continued to get BJs from her and I fucked her in my car a few times.

I'm not sure -
 

I'm not sure that they are that unique...

I have gotten a lot of blow jobs in cars and trucks. Some I was in the driver's seat parked. Some I was driving.

Way back in the day, one of my friends would drive around and my girlfriend and I would have all kinds of sex in the backseat. After we were finished, my girlfriend and I would switch places with him and his girlfriend so they could have sex in the backseat. That's way before anyone had apartments or houses.

Probably the most daring blow jobs and sex was with a married woman, on the living room couch, while her husband was passed out in the next room -with the door open. I'm not sure that he would have cared, he was screwing the secretary at his work. Lol

When I was in my twenties, I was screwing a much older woman in her fifties, she blew my cock everywhere we went.

Office and pier.....
 

Two not very unique ones:

I was seeing a married colleague "J" in the office for a while. I had known her for a long time prior and it started when she called in home to drop a Christmas card off which in itself was not unusual. As I thought she was about to get up and go she said "can I give you your present now?" and knelt between my legs on the lounge floor, sucked me off and swallowed. BJs that followed included my office with several staff still working in the outer office, the office Gents and on several occasions in the car park of a DIY store as I gave her a lift home. We did have sex a couple of times in the office on my desk and on the boardroom table when I was working one weekend, but perhaps the most satisfying was billing the client who paid for our time fucking in a field on the way back from a meeting with them.

The most unusual was probably from my ex on a bench on the end of Clevedon pier here in the UK in the middle of the day with just a banner on the fence protecting the view of people walking up and down. We later got caught by a dog walker on top of the cliffs as she was riding me.

Perhaps not so unique but I also was having an office fling with one of the hottest blondes in the building. As we were both married we had to be creative.

She blew me in many of the car parks around the area, in the bathroom at the office in the dark-room where we developed the microfiche, in the janitors broom closet, in the computer room with the mainframes, or as we drove to meetings downtown.

Bjs and much more anywhere we could without getting arrested and many where we would have if not a just a quickly.

Movie Theater with Married Woman
 

About 15 years ago I was just out of college and I'd lurk and post ads on the old Craigslist personals site when that was going. I was in my 20s and searching for an older woman to give me a blowjob. Eventually I connected with an older, married woman who we had pleasant email exchanges with and agreed to fulfill my fantasy of a blowjob from an older woman.

We met at a movie theater in the middle of the day on a weekday in the spring. It was the movie "Up In The Air" towards the end of its theater run. We sat in the back of the theater and there were only three other people in the theater towards the front. About 10 minutes into the movie she started going down on me. It didn't take me long to bust the first time. The main actress' ass flashed on screen early in the movie and I busted in the woman's mouth shortly after that.

Then we watched the middle part of the movie for about a half hour while she was massaging my cock with her fingertips. When I got semi-hard again she asked if she could suck on it again. And of course I told her yes. So she gave me another blowjob, even though I wasn't as hard as I was the first time. This blowjob lasted for almost the remainder of the movie - so it was a much longer lasting blowjob and I wasn't as hard.

The movie takes a depressing twist at the end of it. And the depressing twist sort of had parallels to what me and this married woman were doing. Although she was oblivious to it because she was going down on me for the last 30 minutes of the movie, I was watching and following along with the plot. So while I thought it was fun and cool for the first part of this encounter, I walked out of the theater a little depressed. Not so much depressed on my own behalf (I was in my early-20s and single), but I was depressed on her behalf.

Not my wife
 

The strangest place I've ever had a blow job, from a woman that wasn't my wife, was in the gents shower block at the top of Neptune's Staircase.

My wife and I were on a sailing holiday with her aunt (A) and her partner. At the time neither my wife, nor her aunts partner, were aware that (A) and I were engaged in a sexual affair. Needless to say (A) and I had not had any opportunity while we were on the boat, but when we arrived at Fort William we went to the showers, and as there wasn't anyone in the Gents block when we arrived (A) snuck in with me and I got a wonderful, illicit, blowjob in the most unusual place I've ever had one.
