In this subtitled Japanese femdom masterclass, Mistress Risa trains her sub to endure her perverse pleasures. Donning thigh-high boots, she tramples his body, leaving red welts on his skin. She uses a stick to poke and prod his most sensitive areas, making him flinch and beg for mercy. But Risa is merciless, pushing his limits with CBT, urethral sounding, and even inserting a ring into his urethra. Throughout, she dominates him with her heels, using them to control and humiliate him. This intense session ends with Risa's boots leaving their mark on his body and her satisfaction at his servitude.
