Kan'in Tokkyuu Matsuba ~Nikuyoku no Gourmet Kikou~

The demand for "specialized" sex slaves in the underworld had grown, and to ensure a steady supply, a new express train was developed. While Michishio handled operations during the summer, this new train, Matsuba, was designed for winter operations. A trap train, luring in even younger women. The conductor responsible for turning these captured women into "livestock" aboard this new train? That would be me—Kaidou Seiji. [Translated from dlsite]
