The women's softball team begins an intensive training camp with former members invited along for the occasion. After a hard practice, Yume Mitsuki returns to her room feeling horny and unwinds by masturbating, nervously playing with her sweaty pussy while watching for anyone nearby. She teases her huge tits and dark areolas with a toy as soft moans escape her lips. Soon the other adult players are masturbating too, apparently turned on by the unfamiliar surroundings. After practice, Yume relaxes in the bath with senior member Hikaru Asagiri. When everyone returns to the room and falls asleep, a dark figure looms over them—is an orgy about to begin?
