Sex is rampant at Rankoh Academy, a co-ed school in a closed off town. The area is also home to the family of Ami Matsushima (heroine of Summer Camp), and Ami ends up transferring to Rankoh Academy at the behest of her parents.
One day Mika Akishino, Ami's childhood friend and the captain of the swim club, asks her to join the swim club, too—Rankoh Academy's swim club has seen better days, is short of members, and is on the verge of being shut down. Whether the club will be disbanded or not will be decided by the results of the national swim competition in a month's time.
While Ami spends a few days thinking it over, Mika succeeds in getting Akira Nomura, a famous competitive swimmer, to be her club's special advisor. However, this guy is not who he seems...! He is in fact the younger brother of Hikaru, the actual famous swimmer. Akira tends to misbehave a lot and is a notorious bad egg. But the regular advisor, the bountiful-breasted Ms. Tsumugi Amamiya, is an amateur swimmer at best and a bit of an airhead, so she believes everything Akira tells her.
When Akira is talking on the phone to an acquaintance about Ms. Amamiya's gullibility, Koji Shirano (protagonist) happens to overhear the whole thing. In an attempt to get Koji to keep his mouth shut, Akira tries to recruit him to the swim club, promising him that in exchange for keeping his secret, he will get some "delicious memories" to savor for his trouble.
Koji dislikes anything that takes too much effort and refuses to join, but a "delicious memory" is forced on him anyway, and so he must join the club in order to pay back his debt.
Although reluctant to be part of something he suspects will be up to no good, Koji agrees to become the club's swim coach after being persuaded by Akira's badass nuggets of wisdom and the encouragement of Mika and Ms. Amamiya. With Koji's influence, Ami and other girls join the club, too.
Under Akira's direction, Koji devises a series of erotic training methods, but the methods he uses end up improving the swimming skills of the club members and they continue to beat their best times (?!).
This is a story of passionate clubmates who take up the fight to save their school from ruin. Through the miracle of a weak, completely unknown team of swimmers cultivating a healthy competitive spirit through rampant orgies, then going on to win the national championship in just a few months in the world of eroge school swimming, this satisfyingly faptastic story dramatizes the trust and eroticism that drives them to achieve their dream.
