In the middle of the night, he sneaks into his sister-in-law's room to ask for fuck In the middle of the night, he sneaks into his sister-in-law's room to ask for sex. When I received the news that my brother was going on a business trip for a week, I quickly packed up my things and drove to my sister-in-law Koizumi's house in a very excited mood. This is also understandable when my sister-in-law and I have feelings for each other because my brother often travels for business. My sister-in-law always complained about the bed because her brother was indifferent to her, she rarely came home from work, but every time Koizumi asked, he flatly refused. That made her very upset, so she came to me to explain. Understanding my sister-in-law's lack of both emotional and physiological needs, I comforted her and decided to help her have this body full of vitality. Our love also grew from there.
