IPX-948 Collaboration work with the older sister from the used bookstore and Azusa Hikari's debut manga original

My job didn't go well and I recently returned to my parents' house, helping out at my grandfather's secondhand bookstore. The countryside was unexciting and was just wasting my time, but I recently found joy. That is to play naughty pranks on Mugi-kun, who often comes to this desolate second-hand bookstore. Mysterious relationship with Mugi-kun who erected and ejaculated after a little stimulation in one serving. Actually, Mugi-kun's sex processing is an excuse and I just want to feel good.
