Recalling the childhood 'doctor play' always stirs a warm excitement in my heart. That innocent thrill explosively revives in this work through the form of 'soap play'! The forbidden incest between real siblings unfolding in their room at night is a continuous shock. The sister, Mei, captivates viewers with her charming smile, youthful fair skin, beautiful large breasts, and perfect figure. Her love for her older brother drives her to turn her room into a soap land and serve him, a blend of purity and eroticism that's unforgettable.

The scenes of their smooth, lubricated skins intertwining are the pinnacle of sensuality. Both siblings are hairless, and the slick sensation seems to transmit from the screen, making one's palms sweat. The brother remains mostly passive, which instead highlights the sister's proactive cuteness, an irresistible development for fans with masochistic tendencies. The raw creampie sex while secluded at home transcends daily boundaries, evoking endless excitement that never gets old no matter how many times you watch.

Although the setting is unrealistic, Mei's natural acting fits the soap play perfectly. This is the first work in the series, and the siblings' smooth combination is at its peak, making later installments feel somewhat lacking. I highly recommend diving into this forbidden world at least once!
