Kokonoe Kanna plays the role of a mischievous little sister who discovers the art of flashing her panties, driving her older brother wild. Unaware of how far to go, she repeatedly teases him with lingering peeks, her underwear and bare butt cheek slipping into view. She makes outrageous demands while flashing him, using dirty talk to arouse her brother's cock until he can't take it anymore and snaps. In retaliation, he thrusts his hard, erect cock at her in surprise, forcing her to take it into her pussy. Each time, she keeps chanting "Onii-chan♪" over and over, her seductive charm amplifying the clumsy, playful scenario even further.
