Shakuen no Eris 1

I’m a hero and my name is Eris Violet of the Flames!

Swinging a sword surrounded by flames with her petite body, she is the strongest hero of the land. Messing up one day, she is captured by monsters and brought back to their research facility where they smear their cum all over her to break her… It seemed like she would never escape, but she does… However, her body can’t help but throb as it gets more and more sensitive. She tries to manage it, but it’s gotten so bad that it’s affecting her duties as a hero, so she asks for an extended vacation. She tells her boss, Kiryuu, about her situation, and he agrees to let her rest in exchange for becoming a filthy blowpig.
