PLOT
An autumn day that feels like winter is coming. I returned to my hometown Yamagata on a business trip and visited my childhood friend Hikari's parents' house for the first time in a while. Her smile is cute as ever, and her innocent side hasn't changed. But we've definitely grown up... Hikari, who hides in her family and seduces me, does not stop her erection, and she secretly released 12 sperm for 3 days. Full subjective.
