A female boss and her virgin subordinate are forced to spend the night during a business trip when record-breaking rain leaves only one room available. Amami assumes sharing will be safe because Takahashi seems timid and inexperienced with women. But after she teases him for being an unmanly virgin, the sight of her rain-soaked body makes him suddenly pounce. The gorgeous, sexually skilled boss accepts everything as her insatiable subordinate stays hard, fucking her in ten sweaty, soaking rounds until morning.
