Anata no Hajimete, Watashi ni Kuremasu ka?

Miyuki works as a receptionist and is secretly dating Chiba, the vice president's secretary, who is popular with everyone at the company. He is flawless in both appearance and behavior, yet he never makes a move on her, leaving her frustrated and impatient. Unable to wait any longer, Miyuki decides to sneak into his bed at night, only to discover that the seemingly perfect Chiba is actually a virgin. She is thrilled by the gap between his composed exterior and his shy, flustered reaction. Excited, she keeps teasing him until he suddenly turns the tables, declaring that he will give her plenty in return. His gentle yet intense caresses melt her whole body until she can hardly stay conscious. As their secret office romance heats up, Miyuki cannot help but wonder: can this really be his first time?
