[Saga no Tame no Saga (Ratoo)] Hero slavization training [Kappasa]

A towering demon girl with horns and a teasing smile corners a blushing young hero, asking if he has charm resistance equipped before offering to service him with her feet and mouth. As the boy struggles to hold back, she reveals her ultimate goal: to turn him into her obedient little slave so they can live together forever. The finale delivers exactly that promise, with the succubus claiming her reward as her new "toy" finally breaks.
