Swimming

When I went swimming in the Middle East in the sea, the water was so warm and calm that I went out a fair way and then removed my swimwear.
Standing there totally naked I then started to fondle my cock which quickly became erect.
The excitement of having other people quite close to me with no idea what I was doing soon created that sensation that all wankers know about and I was soon gushing thick white cum. I struggled to put my trunks back on, but just about managed it before others swam a bit too close.
