In an explicitly adult academy-uniform role-play, Hanakari is selected in a secret vote to become the staff’s anal sex slave. At a mysterious mansion, the quiet adult performer is subjected to brutal anal training by sadistic teachers: hard cocks ram her exposed ass without restraint, men take turns pounding and filling her rectum, and the endless anal relay eventually makes her writhe through anal orgasms. Her mouth, pussy, and ass are used for double- and triple-penetration before the group covers her face and fills her bowels with twelve loads, leaving her begging them to torment Mai’s ass even more.
