MIUM-561 A project pays for a day trip to a zoo. A woman from an ad agency agrees, then sex happens after dark.

A project offers to cover travel costs to anywhere a woman wants to go, and near Akasaka station a woman named Tsukasa stops to listen. She works in advertising, has had no days off for a month, and is tired from work and harassment. She picks a zoo, plays with dogs and ponies, then later in the dark the filming turns to sex, with heavy squirting.
