This work is a forbidden sister-themed AV starring Matsumoto Ichika, with a 130-minute runtime that delivers an intense and captivating experience. The story begins with a shocking setup where a man, exhausted, slips into bed and wakes up the next morning to find not his girlfriend but her sister Ichika beside him. Ichika teases him with a morning blowjob, saying, "You thought it was your girlfriend, didn't you?" and uses her innocent, cute demeanor to toy with him. Initially, the man is forced into sex, but he gradually falls for Ichika's charm, leading to a series of passionate scenes including close holds, butt stimulation, bathing, cat ear toy play, and culminating in forbidden creampies with five consecutive ejaculations that keep the pace relentless. Ichika's acting skillfully portrays the man's psychological descent into a degenerate loop of maintaining relationships with both the sister and the girlfriend, highlighting her seductive elements. Notably, her flawless skin and adorable face enhance her exceptional blowjob skills, while her sensitive pussy and natural bareback sex, combined with her cute moans, create a heart-fluttering effect. It's rare to see a sister-role work where the older sister doesn't appear at all, but Ichika's high-quality performance tightens the entire production, making it highly watchable. After watching it, I too felt drawn into Ichika's temptations, experiencing that irresistible urge to cheat repeatedly.
