Petunia

A man was hanging out in the park, depressed about the boss who took credit for all his work, when a drunken, big-breasted JD shows up! She listens to our hero's situation, and proposes, "I'll be oji-san's girlfriend for a day!" The innocent girl takes him to the arcade, karaoke, a movie... and end up at a love hotel! He is a nice guy who is confused by the situation, but she's happy to get down as a "reward for all his hard work"....
