A few years ago, a certain rumor was a little talked about on an internet bulletin board... You can have a physical relationship with a voluptuous female taxi driver just by telling her 'something'! Encounters happen suddenly...! Who would have thought that the taxi you happened to get in was that 'underground taxi'! She presses her plump, huge breasts against you! You're devoured... and even have creampie sex, which shouldn't happen in the first place...! Your insatiable sexual desire keeps you screwing over and over again... *We've also included an original 'in-car' play for you to enjoy... A collaboration with a popular doujin work!
