The thought was dirtier than the deed...
I don't know why your mom always wears that sheer white bathing suit when I'm in your pool, but I don't warn her because I can see right through it! And I can't miss her black triangle of thick matted pubes when her suit gets wet. Unfortunately my big cock gets hard every time I see that furry mass and my throbbing hard-on sticks so far out I have to stay under water to hide it. Some day when we're alone, I'm gonna stand up and show her what I've got. I bet she likes what she sees. I know I like what she's showing me... hey, maybe it's on purpose!
