Former swimming instructor Rio Ohara. She's known for her large ass and thick thighs, possessing a sex appeal reminiscent of a hentai manga heroine. Though her sexual preferences are normal in daily life, she harbors a deviant fantasy of becoming a mere female sex slave solely for the purpose of satisfying male desire in adult videos. To fulfill this fantasy, numerous middle-aged male actors gather to dominate her—watch her scream in ecstasy as they spit on her face outdoors, force her to drink spit while wearing pantyhose over her head, and creampie her with both cum and saliva during intense bukkake and facial scenes.
