I used to swim a bit but never found female swimmers that hot. I suppose there were some exceptions.
Summer never did that much for me. Amanda Beard is getting a lot of play now as not only the hottest swimmer, but the hottest female athlete period. She does have great cat-like eyes.
For my money, the cutest swimmer was Janet Evans back in 1988 when she won 3 gold medals. True, she was only 17 then so...excuse me. I never fucked her, officer and I was under age myself. She was still cute enough in 92 but in 96 she had plumped up for whatever reason and wasn't cute at all. Great swimmer though. Arguably the best female swimmer the US has ever had.
