It's bringing back memories of playing hardcore sharks and minnows with my (very unrequited) crush at club swim team practice. He was 17, I was 14 and he was so tall and broad-shouldered and muscular like a swimmer.
The way we played since we were all athletes was that the minnows could only be caught by the sharks on the surface so imagine diving down to the bottom of the deep end and swimming as hard as you can at the bottom of the pool only to feel two big strong arms wrapping around you from above/behind and a long naked torso and long muscular legs pressed against you and you put up a fight, a bit, because you're no damsel in distress; this isn't lifeguard training and you aren't playing the victim.
And suddenly you're dragged to the surface and BAM, you're out. And you just had a defining memory of puberty because OMG that was the sexiest thing that ever happened to you.
