In this adult role-play, my younger childhood friend Sana stays with me for five days while both families’ parents travel together. She acts cold and cocky, yet slips into my bed because she is afraid to sleep alone. She even puts on a school-style swimsuit to bathe with me, claiming she is too scared and embarrassed to go in alone. Her bossy attitude keeps me off balance, but every provocative move hints that her prickly behavior may be hiding genuine affection. An intimate first-person tsundere cohabitation story.
