Just treading water like that in the ocean without any swimming trunks on would have me all aroused and hard, likely inviting a helping hand to get me shooting out a messy load of sperm under water. I'm hard, hot and need to do that now!
Bring back when i was in Greece i saw a mature guy swimming at night so i joined him we started to talk asked him shall we play that when he kissed me and i felt his cock rubbing on my leg so i went under water and sucked his cock he got hard he fucked me in the sea
