Blackjima appears to be a slender beauty, but her personality is timid and she can't refuse requests, making her a weak female teacher. Due to her personality, she ends up accommodating the impure demands of male students and even helps them ejaculate. The one who witnessed this was the principal, who embodies vulgarity itself. Summoned to the principal's office, she is threatened with disciplinary dismissal and ends up in a romantic relationship with him, almost like a slave contract. Initially, she hated the act, but before long, she starts dripping bodily fluids from her vagina, transforming into a vulgar female. Whenever she is summoned by the principal, she smiles while soaking her crotch and reaches orgasm.
