This year, my mother-in-law turns seventy. Hearing that she's been getting tired easily, I started rubbing her back, and inadvertently got excited seeing her underwear peek out. Meanwhile, my mother-in-law is so engrossed in housework that she doesn't notice her underwear showing, exposing herself without a care. I try to shake off these impure thoughts and attempt to help her, but the situation takes an unexpected turn... 'Mother-in-law, I'm sorry! I can't hold back anymore!'
