Rikka Natsukawa was the popular idol at school, adored by everyone. However, her secret—being a boy who lived as a girl—was discovered by the teachers, who decided to play a cruel prank on her in the classroom after school. As they exposed her hidden truth and taunted her trembling, humiliated form, the teachers began stimulating her lower body, relentlessly targeting even her anal opening. Unable to withstand the overwhelming pleasure, her face twisted in ecstasy as she was penetrated by the teacher's wicked cock, transforming into a state resembling a fake vulva. In that instant, she cried out "Hii~ Hii~," completely surrendering herself to ultimate, exquisite pleasure.
