One autumn day, I felt the coming of winter. I returned to my hometown of Yamagata on a business trip and visited my childhood friend Hikari's family home for the first time in a long time. Her smile is still as cute as ever, and her innocent side hasn't changed. But we've definitely grown up... Hikari seduced me in secret from my family, and I couldn't stop getting an erection, and I came 12 times over the course of three days. The whole thing is in subjective opinion.
