"I'll let you go, so please lose the next game." Nakamori Kokona, a self-sacrificing, meat-eating manager who sells herself into slavery for the team, SONE-447

Manager Shinshina has two faces… To achieve her dreams, she wholeheartedly supports her team, projecting a positive image of dedication. For the team's victory, she will willingly go to rival schools and offer her body as a prostitute. Her team members are unaware of Shinshina's other side; whenever they win a match, they happily say, "Our practice paid off!" Shinshina enjoys seeing such smiles. She not only licks the penises of key players on the opposing team, including the captain and coach, but also their anuses and testicles, serving them with complete obedience. She engages in sexual intercourse with her wet tongue and vaginal fluids… In fact, she is a slender woman who can make men infatuated. As victories increase, her behavior becomes increasingly extreme. Although she feels guilty, this thrill becomes an addictive pleasure, and she becomes a promiscuous manager. Because her love for the team was so intense, she couldn't stop, and eventually she even had pleasurable, chaotic sex with everyone from the rival school until she ejaculated, after which she would perform oral sex to clean herself up... "I promise, I'll take you to the national competition, Shin-chan." This is the story of a brave female manager.
