"Would you like to challenge a game for a cash prize?" Azusa is invited to participate in a game where the rule is simple: if a wet spot appears on her panties while watching an adult video, she must face a punishment. The 21-year-old eagerly joins, aiming to win the prize money, but within just five minutes, a clear stain forms. As punishment, she is forced to warm the judge's cock with a handjob. However, Azusa is already aroused, and with just a little cunnilingus, she's quickly driven into a highly excited state. Her sensitivity and innocence are part of her charm.
