Miki Yamase, boasting a dynamite body with a 105cm bust and impressive J-cup breasts, takes on a 120-minute non-stop sex challenge for the first time. Despite admitting to feeling nervous about this uncharted territory, she's overwhelmed by the intense desire of the male actors. Her clothes are quickly disarrayed as the men become aroused, revealing her abundant breasts. She starts to moan softly as she experiences intense sensations. Cunnilingused and penetrated, her sensitive vagina makes her legs tremble uncontrollably. Leaning on a sofa with her legs spread wide, her engorged vagina is hand-jobbed, leading to the release of precum and vaginal fluids. Finally, she receives a large penis both orally and vaginally, her screams echoing through the studio as she's overwhelmed by the size. Yamase's vagina is constantly engaged, with no time to rest as she continuously interacts with different men. Her vagina, having reached multiple orgasms from the endless stream of large penises, grips them tightly. One man, unable to hold back any longer, ejaculates onto her raw vagina. The JAV also mentions a live chat feature where viewers can interact with wives and mature women.
