Kimi ni Soba ni Ite Hoshii

When Yura opens her eyes, she finds herself stark naked, lying next to her boss, Aoi Isshiki. It all started on her way home, when Yura declared that she didn't want to go back. No matter how much he wanted to hold back because of his position at work relative to Yura's, stirred by her words, he could no longer control his body. At work he's a strict boss, but in private he's a kind-hearted man who sweetly calls Yura by her first name!
