"Huh? Sister-in-law! Why are you here?" In an effort to prevent my husband from finding out about a mistake I made, I turned to a loan shark and ended up with a huge debt, so I decided to work at a soapland to pay it off. One day, the worst customer came to the store. It was my brother-in-law, who I hate, a disgusting pervert with a strong sex drive. He took advantage of my weakness and called me in almost every day to be creampied. Gradually, I got used to his thing and finally climaxed. "My sister-in-law's free unlimited soapland is the best."
