Tired of the mundane, Yui seeks excitement in new forms of sexual exploration, discovering a fascination with scat. With her partner’s assistance, they bring her desires to life. The video begins with her partner eagerly rimming and devouring her anus, followed by urinating into his mouth. She then proceeds to defecate onto a plate, releasing all she can while receiving an enema to extract any remaining feces. As she eats her own excrement, a second man feeds her even more, resulting in her face and body becoming covered in filth. Yui then pleasures herself with a vibrator while continuing to consume her feces.
As she finishes, she turns her attention to pleasuring her partner orally and with her large breasts. He then returns the favor by vigorously penetrating her vagina while a second man smears more feces onto her face and mouth. The video concludes with Yui on top, riding her partner until he ejaculates inside her.
