Recently moved in, Kato steps out onto the balcony for a smoke during lunch break and notices the neighbor's wife hanging laundry. Realizing he forgot to introduce himself, he visits her house later that afternoon with a gift of sweets, but accidentally picks up a pair of women's panties in the yard. Thinking they must have blown away from the laundry, he glances through the living room window—only to discover the wife inside, not wearing any panties, lewdly indulging in masturbation. Overcome with shock and excitement, Kato can't suppress his arousal.
