I'll put it in real adult words. Go and please yourself, sexually.
Updated first post. The animation is a bit different than the CM, but you can never doubt KyoAni + AniDo! - Read few days ago about Animation Do and they're related to KyoAni, apparently they handle everything else and special effects from KyoAni's work.
Looking forward to it. Not because it's sports or swimming, but because this is KYOTO ANIMATION!!!
