Mesu wo Karu Mura English Subbed

Ryoshuu no Mura
A group of female students are on their way to a high-altitude training camp for the astronomy club when their car gets a flat tire and they’re stranded. A local person rescues them and invites them into the village. However, it turns out that the village has a tradition of capturing women from outside and forcing them into village marriages. A beautiful teacher risks her life to protect the students held captive in a storehouse, but when she’s taken to a large hall, she finds the men stark naked and erect. With their clothes torn off and tortured relentlessly on the spot, her body reaches its limits. The teacher, losing her mind, offers up her students as scapegoats. Meanwhile, the three students left behind in the storehouse have their clothes stripped and their hands and feet bound. One by one, their bodies are trained by the villagers, until they are physically and mentally broken and reduced to human slaves.
