DASS-507 Delivery service from an acquaintance. I called a delivery service with no actual sex, and a brash junior showed up. Hinako Matsui

Ichiikawa's subordinate Hinako is cute and good at her job. Initially, Ichiikawa even taught Hinako how to do her work, but in just a few months, she became more favored by the company than Ichiikawa and started looking down on him. Hinako's brash and aggressive way of speaking really gets under his skin. Amidst this, he discovers something called 'Friend Delivery Helper,' where an acquaintance comes as a delivery helper girl, and out of half-interest, he calls for one, only to have Hinako show up.
