The bound girls' bodies are no longer treated as human, but used solely as vessels for receiving sperm. Penises are forced through holes cut into the crotch of their bloomers, raping beautiful big-breasted girls. Their huge breasts spill out of tight school swimsuits, and one girl is forced to urinate before being used as a tool to clean up semen. Another girl in uniform has a penis shoved deep into her throat while restrained, forced to swallow despite her tears. A petite, innocent-looking girl with short hair is violated in her torn sailor uniform, her vagina filled with sperm. This is a compilation from the Seifuku series, depicting the abduction and captivity of four schoolgirls.
