Fireworks festival suddenly canceled, leaving beautiful women in yukata wandering the streets. A pickup guy spots a cute, idol-like girl in yukata named Toyota Yuu and persistently invites her to set off fireworks at his place. Yuu reluctantly agrees, saying "Just for a little while," and follows him home—though it's still bright outside. The guy, breathing heavily, forcefully grabs and gropes her shoulder. Even the fabric of her yukata brushing against her nipples makes her gasp, "Hau, haa..." Unable to hold back any longer, he slips his hand inside her yukata and starts swirling his tongue around her nipple. Yuu trembles, overwhelmed by waves of pleasure.
