"What! My clumsy subordinate wants to be Ms. Hikari's boyfriend for a day?!" Hikari, whose busy work schedule has delayed her wedding, asks me to be her fake boyfriend for a day to escape her parents' pressure! What started as just a casual visit to Kinoshita's house turned into a thank-you gift of oral sex in the bathroom! We even had unprotected sex while in bed together! Her condition for continuing as my boyfriend is that I also provide oral sex services at the company! My dream of having oral sex with my boss during overtime! The loving unprotected sex puts my parents at ease! Will this really lead to marriage?
