I am a bear type guy, quite fit, in my early 40s, I have always loved to swim and find this activity normally relaxing after a stressful day at work.

This evening, after a busy day, I went to the local swimming pool, its a great deep pool, some 4 metres deep. Tonight it was a 'men only' session. Normally there is some good looking men there, but tonight was something else!

I normally swim a couple of laps then go to the deep end and practice my 'breath hold' at the bottom of the pool to see how my stamina is improving.

This also has the added bonus of if I am underwater a little too long, I start to get an erection - for this reason on top of my swimming trunks I wear some looser shorts! - so that my erection is not obvious!

I set my stopwatch and I had been underwater for about a minute, stating to get ready to come up for air - I spotted another guy, quite hairy, mid 30's, swimming above me, he looked down and smiled and grabbed his own bulge. Of course, by then my own erection was starting to become rather obvious. I surfaced as he swam away, I had been underwater just over a minute and a half.

I swam a couple of more lengths, went back to the deep end, hyperventalated for a short while, took a deep breath and sank to the bottom of the pool - waiting for my hunky man to pass by again.

He swam down anad joined me at the bottom of the pool !, his bulge was rather obvious... he only had swimming trunks on, not the benefit of erection hiding baggy shorts...

He started to touch his self through his swimming trunks - all I could think of was wanting him to pull his cock out of his swimming trunks and put it in my mouth... it is as though his cock would be the oxygen I would soon need!

I was sat on my hands, I could feel myself getting very hard now and wanting to cum, by watching this stranger, also underwater, running out of air but with an erection, continually touching himself through his swimming trunks...

without even touching myself I felt hard cock shoot warm spurts of cum filling my swimming trunks, I was running out of air now but did not want to surface, I thought I would drown, also my sexy stranger started to lose air through his nose, so surfaced, still with his erection.

I managed to stay underwater for another 30 seconds or so, I pulled my now semi hard cock through my swimming trunks and shorts to see my sperm start to float away...

I surfaced and checked my stopwatch, I had been underwater almost three minutes, it is the best and most intensive orgasm I have ever had - I wish now to see him again and explore more sex scenarios underwater...
