This happened about 5 years ago, shortly after my divorce. I am from the Philly burbs and belong to Harley riding group. A fellow member had suffered a loss, so to show support, a group of us would meet at her bar just outside Philly. There was maybe 8 to 10 us us, mixed crowd, at any givin time.
At the bar, my lady friend, lets call her 'J', brought a gal pal of hers (her name was 'A') one night we all met at the bar. She and I hit it off very well, and she mentioned she liked my build (6'-1, 195) and mentioned also that 'J' had spoken to her about how well endowed I was (8' when hard, slight curve too).
So, naturally the conversation turns to sex in all aspects, and her enjoyment of masturbating men in particular. Well, needless to say, that got my attention!.....it also caused a swelling in my jeans, which she noticed quite easily. She offered to take care of my growing bulge, and since I wasn't wearing any underwear (usually don't during the warm summers) I dared her to unzip me, pull it out and jerk me off, under the bar.
Now, the bar was pretty dark in our area, with the most lighting at the pool table area on the other side of the bar. But, there were people a few chairs down on either side, and probably 15 or more on the opposite side of bar, playing pool and whatnot.
She took me up on my bold offer, reaching discretely under the bar, slowly lowering my zipper, reaching in and (struggling just a bit) to pull out my now fully engorged member. Having done that, she remarked, 'Well, 'J' was right!...you are very big!' I chuckled at that and asked her to proceed with completeing the dare.
As she stroked my hard cock under the bar, she took her time, as we chatted, sipped our drinks and watched the others in the bar. Some friends even came over to our spot, and as I made sure I was still mostly facing the bar, she deftly turned around to face the friends, and switched hands, still stroking me even as we chatted!
I was getting more and more turned on by this as you can imagine, and once the friends drifted off, she began to stroke in earnest, occasionally leaning in to say something, and grabbing my ass at the same time. We were both enjoying this 'under the bar' stroke job!
Well, after about 15 minutes of this, I blew my load under the bar all over the wall portion directly in front of me. She continued to pump, with me trying not to move my hips in a humping fashion , as that would have given away our little game.
Once done, she wiped the head of my now dripping cock and smiled.
After I zipped up, we chuckled about how arousing that was and decided to go out to her car and further explore each others passions.
I slept very well that night.......lol
