HZGD-254 Brother goes on a business trip far away and the ending

I can't stand my horniness anymore, my sister-in-law always dresses "skimpy" when she's at home and she doesn't even... wear a bra.
My brother goes to work from early morning until late at night, his job is a manager so he has to leave early and come home late to monitor the employees, count the goods, and report to the boss. My sister-in-law does nothing but housework at home, I'm unemployed so I stay home with her all day. I'm not a lustful person, but my sister-in-law "accidentally" arouses me with her sexiness. She always wears a cool outfit at home, which is not surprising, but what's being said here is that she doesn't wear a bra, letting her big, firm breasts loose, and not only that, she often reveals the white panties she often wears.
As a man, how can I stand my lust when I see her dressed like that all day long, and that day,... I couldn't stand it anymore...
