Cool de Smart na Hakozaki-kun no Nasakenai Kao Mite Mitai

Hoshizaki is a popular guy with the top business results at the company we work at... he's very cool, and seeing him as my rival, I am highly jealous of him. After I quit my job, he suddenly asks me out for a drink. One thing leads to another and... Who could have ever imagined that he's actually a very cute masochist? I'm going to make him cry and moan with my touch... to wipe that smart expression off his face and make him squirm in shame. (Source: DLsite, translated)
