とある闇市場にて (Pixiv Fanbox)

体力仕事に特化した亜人を開発する過程で生まれた個体。乳房が巨大すぎて労働の邪魔になるため闇市場に売却された。慰安用としても一般受けはしないため、あまりいい値段はついていない。

An individual born in the process of developing a subhuman specialized in physical work. Her breasts were too huge to be used for work, so she was sold on the black market. Even for comfort, they are not popular with the general public, so they do not fetch a very good price.
