MIDE-992 A seemingly ordinary but actually carnivorous childhood friend and I spend five days of being eaten together Kotoneka

I have a childhood friend in my class, but we haven't talked much lately. However, while our parents were on a trip, she stayed at my house to take care of things... It turned out that despite her innocent appearance, she was an insatiable sex maniac. She said she couldn't sleep alone because she was scared and then got into bed with me, showed off masturbating at the school we attend, and even rode me while I was already climaxing. I was drained for five days straight.
