Saya had never felt any interest in men, but she couldn't bring herself to tell anyone. One day, she decided to visit a women-only mental clinic. There, she met a female doctor who treated her patients with gentle, calm demeanor—but behind her sweet smile lay the hidden fangs of a sadistic lesbian. The therapy began with soft whispers near her ear and subtle body contact. Yet the doctor was like a female spider, eagerly awaiting her beautiful prey. Through repeated cycles of punishment and reward play, the doctor gradually subdued Saya's resistance, leading to an intensely thrilling lesbian BDSM experience as if draining her sweet fluids completely. Throughout this process, Saya's heart slowly changed, awakening entirely new emotions within her.
