FNS-106 My balls are already empty… A hopelessly unpopular guy whose first time was taken by a sex-obsessed childhood friend, Yui Hina, and who was worn out after being used in place of a vibrator

I returned to my hometown to find a job locally and was reunited after a long time with my older childhood friend, Hina-chan. She had become a shut-in and was living a lazy, self-indulgent life, watching streams in loose clothing and snacking constantly. When I visited her room again, I caught her absorbed in private self-pleasure. From that day on, I was repeatedly used as a substitute for her toy and ended up being worn out over and over again.
