Imagine having Mio Ishikawa as the hardworking junior coworker who brightens every day at the office—and secretly loves you. After completing a major project, the two hold a private celebration. Although her senior already has a girlfriend, Mio pretends to be drunk and insists that if she forgets everything tomorrow, it will not count as cheating. She kisses him, leads him to a love hotel, and awkwardly but earnestly begs for sex. As she rubs against his erection, he slips inside her and she finally confesses her love. Overwhelmed by how sweet and sincere she is, he gives in and fucks her again and again.
