Holding in pee, a sporty schoolgirl with a plump body is running around the town. The story begins when she rings the doorbell of your house...

After you let her use the bathroom, she finally gets relieved.

Upon leaving your house, however, it suddenly rains so that she has to take a shelter until it stops raining, but it lasts for long time.

Staying at home two alone, the mood becomes uneasy when she found your porn books, when you saw her panties on the mirror...

Driven by the aroused mindsets of each that reach the climax, these two slide into sexual intercourse eventually...

But this is just the beginning, as the story continues afterwards...
