SCOP-553: 我很幸運，我的父母再婚了，我有一個年輕又超級可愛的妹妹！ - 我會住在一起，但我不能停止和幾乎同齡的嫂子在一起。 - 晚上父母不回家，偷偷在姐姐的房間裡過夜！

I'm lucky that my parents remarried and I got a young and super cute sister! - I will live together, but I can't stop being with my sister-in-law who is almost the same age. - At night when my parents don't come home, I secretly set up a night in my sister's room!
