The husband, desperate to have anal sex with his beautiful wife, hires a dark job contractor for a certain request... Sumire, who is kidnapped and confined by a man she doesn't know. Bound with rope and unable to move, Sumire's anus is subjected to various toys for expansion training, and she soon awakens to the pleasure of anal slavery. Her anus, covered in intestinal fluid, is violated by a thick penis in a brutal fuck! The husband who plotted the plan also intrudes, and Sumire, entranced by simultaneous anal and vaginal attacks, murmurs "Ass is the best" as she reaches climax.
