Sweet Sweat in Summer: The Naughty Girl and Her Ripe Scent is a Japanese adult visual novel about a relationship between a man and a sexually curious girl whom he meets while visiting his hometown during the summer. Like the title implies, this eroge focuses on fetishes surrounding female sweat and body odor, but contains lots of conventional sex as well. At certain points throughout the game, the player must make decisions which affect how the story unfolds. It features voice acting for the heroine.

The player controls Kouhei, a young man who takes a trip to his hometown to relive some old memories. To his surprise, Kouhei finds the town completely deserted except for a girl named Karin Nekodou who has been lonely ever since her "sensei" disappeared. Since Kouhei plans on sticking around to explore his surroundings, Karin asks Kouhei to become her new "sensei" until her old one returns. With no men in the town except for Kouhei, the sexually frustrated Karin is eager to experience all the things she has heard about sex, and makes Kouhei into her very willing test subject.
