Karen Yuzuriha is subjected to 12 relentless hours of extreme sensitivity training with nowhere to escape. Soon after arriving at the studio early in the morning, still almost bare-faced, a man suddenly attacks her and kicks things off by making her cum as he eats her pussy from behind while she stands bent over. Even during the interview, she is dragged onto the bed and drenched in oil for deep cervical stimulation, screaming, “Stop! I’m already cumming!” as she repeatedly arches and squirts. Restrained toy play and a Spence breast-gland orgasm technique force her body to relive earlier pleasure, pushing her through climax after climax until she nearly blacks out. It ends with a fluid-soaked threesome and brutal big-cock pounding that leaves her convulsing and dazed. Even after proving how sensitive she has become, the glassy-eyed Karen keeps being made to cum until it is almost time to leave.
