Sara Yurikawa, the older sister, experiences her first-ever cum drinking session. Though nervous at first, she confidently downs thick, relentless streams of semen with an erotic smile, saying, "This might actually be pretty good♪" Later, dressed in a nurse outfit, she intimately faces off one-on-one with participants, swallowing every last drop of sticky sperm and showing off her satisfied expressions one after another. The highlight comes when she masturbates openly, her pussy fully exposed, surrounded by six erect cocks, making lewd ahegao faces as she catches the white, cloudy cum on her tongue and swallows it all. With 21 full swallow shots, her erotic charm is fully on display.
