ONEZ-187 Sister is a Dedicated Lewd Maid Vol.001 Reika Hashimoto

About the fact that my longed-for sister was an ultra-perverted slut maid! I have a much older childhood friend who is like a sister to me. Her name is Reika. She has excellent grades, is beautiful, and is truly out of reach, plus her family is rich. However, her parents disappeared after accumulating a large amount of debt. Reika became our family's exclusive maid... But as we started living together, I realized that my sister was incredibly vulgar and perverted. What will happen to me?
