For me, Portio was Pandora's Box ... Emi Dan

Emi is a dissatisfied wife, whose husband is too young to satisfy her desires. She finds comfort in Guanpu, a man who helps her discover her sensitive zones, including the uterine neck. As they engage in intense and passionate sex, Guanpu uses his skills to stimulate Emi's deepest pleasure points, providing her with an unforgettable experience. With a focus on deep penetration and uterine neck stimulation, their encounters become increasingly erotic and satisfying.
