Koushoku no Chuugi Kunoichi Botan

Botan is a female ninja on the verge of marriage. Her uncle, also a benefactor, asks for her help to support a declining samurai estate and its beloved lord. Following his invitation and orders, she hides from the master she should serve and allows her small body to be violated.

Despite viewing her actions as duty, her body inevitably responds to the pleasure. Botan must navigate the conflict between her sense of obligation and the growing physical sensations she cannot control.
