Saya Akagi is an assistant professor at a certain private university who specializes in the history of early modern punishment.However, he was not only a research field, but also had a propensity to indulge in intense self-bondage masturbation night after night, arousing intense sexual excitement with cruel paintings of the Edo period.Under the plain teacher's clothes, a well-ripened body that could not be hidden was breathing, but she was lured into a villainous binding art dojo by an unmatched student who had a strong desire for Saya from before and was trampled.His ripe areolas and nipples are bullied, and his coveted beautiful buttocks are teased with anus and given continuous enema.
