[Chinese]NATR-462 Brother's wife Kyoko

I am a part-time worker and currently live with my brother and his wife. My older brother is a salesman who works for a trading company. Every day I'm chased by my quota, early in the morning and late at home. There are days when he doesn't come home because of long overtime. That's why I spend a lot of time alone with my sister-in-law Kyoko. Kyoko is beautiful and kind, and treats me like her friend. Until she looks like that...
