Recently hired Karen Yuzuriha accompanies her superior, Takeda, on a business trip. On their return journey, the Shinkansen breaks down and service is suspended, forcing them to stay overnight locally. Still drunk and feeling sluggish, Karen is taken to a hotel where only a single room had been reserved—part of Takeda's deliberate plan. Though she tries to resist, she's quickly overpowered by his aggressive techniques. Unable to withstand his seduction, her body gradually succumbs to him. Her soft, exquisite body is pounded intensely as she receives deep, passionate foreplay, repeatedly impregnated with creampie after creampie. By the eighth creampie, both her mind and body have completely fallen under his control.
