This role-play is performed by adults. While my wife was returning home to give birth, my sister-in-law, Mion, came to help with the housework. Mion cleans the room in place of Kenji, who can't clean at all. Every time you vacuum, you can see a glimpse of her breasts, and when she wipes, you can see her unprotected panty shots, and you can't help but look away. Mion, who was taken aback by Kenji's naive reaction, reached for his crotch and said, ``I'll take care of you, not just the housework.''
