I received an unexpected email from a senior who has been taking care of me for a long time. "I want to use your room for a waiting call girl, can you lend it to me?" The call girls who kept coming in acted as if it was their own room, relaxing without caring that I was there, and even started changing clothes, showing panties and cleavage. I was mistaken for a part-timer and made to practice, and the erotic harem life with the bold and defenseless busty call girls began, more than I had imagined!
