Koji An opened the door to serious torture with her previous work "Torture Deep Throat". The new torture theme prepared for her is anal fisting! The one who thrusts his fist into her is the iron fist master, Misaki Yui! An screams and writhes in pleasure as fist master Yui holds back with anal fisting. The pleasure torture, which also involves iron man Kato Taka, will continue forever.
