Two sadistic men kidnap Yuuriue, a married woman they met through a dating site, and brutally dominate her as their sex slave. Though she verbally resists, the vibrations of the toy make her hips tremble uncontrollably, and she's repeatedly forced to endure relentless stimulation. She serves them in doggystyle and cowgirl positions until they're satisfied, eventually losing herself completely, frantically grinding her own body as she reaches climax after climax. A continuous assault of absolute domination and overwhelming pleasure.
