A video of a girl-only prostitution featuring the older sister Aya and the younger sister Koko. From the older sister's reaction, it seems she has sex with several men, while the younger sister is indifferent to sex, and the "old man" does whatever he wants to her. Judging from the tan lines, it seems the filming took place between summer and early fall. This is a vivid video of prostitution, with the younger sister saying that the erect penis is "gross," the older sister calmly giving a blowjob, and the older sister getting creampied after being penetrated raw. *There are no performers under the age of 18 in this work.
