一発いかが？必ず孕ませるよ。- Would you like one? I'll make you pregnant. (Pixiv Fanbox)

　崇めると不妊が治るという悪魔さん。彼女は男でも孕ませるくらい効力があるが、一度崇めると他の誰ともセックスできない体になってしまうという曰くつき。

She is a demon that cures infertility when worshipped. She is so powerful that she can impregnate a man, but it is said that once she is worshipped, her body becomes incapable of having sex with anyone else.

　こんな凶暴な物と命の危険をさらしてでも相手をする人はそうそういないので素振りで我慢する悪魔さん。

There aren't many people who would risk their lives to deal with such a violent thing, so the demon puts up with the pretense.
