It's been half a year since Takashima became friends with Shiraki, a regular at the pachinko parlor he goes to. She's a friendly gal and they have such a good relationship that they're even comfortable enough to exchange stories and dirty talk. After Takashima tells a story about being blue-balled at a soapland, Shiraki comes up with an exciting proposal: dirty car love that'll drain his tank till he's empty.
