(The only thing fantasized is the underwater sex, doing that specific dive naked and me diving with that guy — everything else is true).
One night, I went biking dressed exactly like that:

At the cruising spot, it doesn’t take long to pick a guy; we go in the bushes and he fondles my bulge while we kiss. He says that I my gray tights are so hot… Then he goes down and pulls down the tights to suck my dick for a bit, then he turns me around "Ooooh! I could so much eat that ass!"
— Well, we can go to my place, it’s not far…
So we go to my place. As we get in the vestibule, where I kept my bike and my SCUBA tanks (they’re heavy so I don’t want to lug them in the house and besides there’s room enough there).
— Oh! You’re SCUBA diving! Oh wow!
— You dive too?
— Yeah.
— Oh that’s cool!
So we have sex (blowjob, rimjob, he fucks me — missionary style —, the usual.
We decided to get in touch.
Some months later, in late August, as he was off on weekdays, I decide to arrange a "special" dive with him… It’s at the end of the sumer, the St-Lawrence is warm, and there’s an interesting drift dive I’d like to do, in speedoes (now you can see my drift…).
In a drift dive, you just get caught in the current; usually, you get a dive flag and a boat follows you on the surface.
