The "Ganman Bijin" project was launched with the concept that "women who can endure are beautiful." Sara, who has a slim waist and an erotic body, is challenged to endure the squirming even when she is being held back! It's a big hurdle for Sara, who is easy to get excited with, and even though she thinks she is holding back, she is still squirting because she is eager for the dick. The more she endures, the more she gets addicted to it and the erotic voltage rises! She is brought to the brink of orgasm, and then she is released from her orgasm endurance and cums over and over again, making her consciousness go haywire!
