You left work late today and then slept through the station by dozing off on the subway. You get off at the nearest station. It looks like this station is called Kisaragi Station, although you don't seem to have seen this station on this line before. It seems to be outside range, so you can't call someone to pick you up. Whatever, it's not a big deal to sleep here for one night, and then take the subway back in the morning. So, you sit on a bench and start resting. Just then, you notice a girl who looks like a high school student. She wears a very long trench coat, but it seems that this trench coat can't completely hide the protrusion of her lower belly... She notices you and walks up to you.

"Hey, Onii-chan. Can I interest you in becoming a daddy?"

She smirks playfully, twirling a lock of her twintails around her finger.
