A burst of shocking betrayal and arousal switches! When the unstoppable urge led to an attempt at immediate penetration from behind the girlfriend, the unexpected appearance of her sister left me breathless. The setup, where the sister's lust switch is triggered by the sudden insertion, driving her to crave the penis, delivers both a sense of realism that pierces everyday gaps and simultaneous excitement.

First, Yume's charm shines through. Her beauty remains unchanged across many works, standing out even in such a scenario. Ruru, whom I usually avoid, displays a cuteness in this piece that gives a fresh impression. The tension and sensuality woven by their interactions have a power to deeply draw in the viewer.

Hanamiya Rei showcases her acting with full use of her beautiful breasts and buttocks, and her sensual moans add depth to the entire work. Especially, the interactions centered on her buttocks, combined with skillful camerawork, are rendered highly erotic. The other actresses are also beautiful, and the well-balanced casting enhances the quality of the production.

The post-ejaculation realization pattern is indeed classic. While some may find the depiction after the woman's climax unimportant, this work carefully portrays the emotional fluctuations at that moment, offering a realistic sense of presence. Overall, the unexpectedness of the situation and the passionate performances by the actresses combine to provide an exhilarating masterpiece that never grows stale.
