Modern AU. Harry hates the fact that he can't swim, despite being 18. But his terrible relatives never let him swim growing up, so was it really his fault?
So Harry decides to take swimming lessons before taking a beach vacation with the Weasleys and Hermione.
Thinking it might be a little embarrassing learning how to swim so late, Harry decides to request private lesson, figuring he'd get some relatively pretty instructor but nothing more.
And boy was he wrong!
His private swimming coach was a 21 year old goddess among women with perfect tan lines, a flawless body and absolutely criminal accent.
A dauntingly beautiful French woman, Fleur Delacour.
Suffice it to say, but Harry doesn't want her getting close to him in the water, and she doesn't seem to realize what she's doing to him.
