Private military company GIGA launches a new mass-production cheer squad unit called "Cheer V." Among its members are genetically modified individuals, including one codenamed ZERO. Despite being a rookie, she is abnormally strong, highly elitist, and notoriously silent and cold, causing her to be ostracized by the rest of the team. Her secret? She was born with a penis due to genetic manipulation—a futanari. Overwhelmed by unbearable sexual desire, ZERO repeatedly masturbates, climaxing again and again. Her secret is discovered by Promethee, a senior member who despises her. Under the guise of a Cheer Knights tradition, Promethee measures ZERO's body, her hands slipping into her panties and finding ZERO's penis, which instantly becomes rock hard. Promethee thoroughly stimulates ZERO's shaft, eventually bringing her to multiple consecutive ejaculations through intense handjob, forcing ZERO into a classic ahegao expression while giving a double peace sign. Used as a tool for pleasure, ZERO succumbs completely to Promethee's control. In the end, she is broken and dominated, submitting entirely to her senior. [BAD END]
