Suddenly, a clear and pure sister-in-law appeared. I thought she was serious-minded, but it turns out she's a sex maniac? One day, I witnessed her communicating with various sexual partners. When I begged the sex-loving sister-in-law to let me do it, she said 'It's okay if you use a condom,' so we tried it, but she didn't seem to be enjoying it much, so I secretly removed the condom and did it raw. She was extremely sensitive and came over and over!
