Working at a rejuvenation massage parlor, Saki starts with a normal massage, gradually progressing to more intimate treatments like prostate and testicle massage for deeper pleasure. Finally, she performs the shop's popular original service—outercourse massage. Her adorable face and earnest movements as she carefully grinds her pussy against the client are utterly captivating. Unable to resist, the client makes a bold request: "Can I just go ahead and insert it?" Saki immediately protests, "Eh? No penetration allowed!" But overwhelmed with desire, he ignores her words and gently pushes the tip of his cock into her pussy. At that moment, Saki's panicked voice echoes out: "Ah, no, sir, stop! You can't insert it... no!"
