Okuchi ga Ecchi na Jakuten datte, Rival no Elite Douryou ni Bareteshimaimashita

Suzuka Takamine has worked at a major business consulting company for three years. At the office, she’s called the unattainable ’Takane no Hana’, because of her work performance and good looks. But she has a complex. Her mouth is overly sensitive. When her mouth is stimulated, her body reacts with a jolt and her eyes overflow with tears. One day, the secret she’s been hiding from everyone is discovered by her colleague; the company’s ace, Kouma Zaizen. To get caught by her rival, of all people, could have been the end of her, but Takamine’s reaction seems to match Zaizen’s fetish to a T.

”What a sexy expression… So cute. I want to make you cry more.” He’s a little sadistic and totally infatuated with her, complex and all.
