MUM-128 The first buttocks in my life. It is taught that anal is another mako. Saori Kurashina 140cm (Hairless)

I was told by a man, “You’re small.” She seems to be interested in the buttocks and has put her finger in it. I didn’t go deep enough. I was told “I have to expand” and saw a big stick. I don’t remember much after that. However, the inside of the buttocks was hot and there was a white thing on the thigh.
