Flasher aunt came out in lake town

Yuuko's husband disappeared, leaving a debt behind... Raising her son Masao alone would have been too difficult, so Yuuko left her crying child at a facility. 20 years have passed since that day. Yuuko has paid back her husband's debt in full, and her mind keeps wandering to Masao... One day, wondering if she can meet her son again, Yuuko comes up with an ingenious idea. Her plan is to expose the boobs that Masao so loved, giving her son a reminder of his Mother.
