Tempted by the huge sum of 100,000 yen for a single scene, Sayu awakens her own skills in the cowgirl position. With a great figure and large breasts, she's a naturally attractive and pure beauty who seems like she'd be popular with men—but her intensely passionate performance exceeds all expectations, shocking everyone who watches. She vigorously grinds her hips, pursuing creampie sex to the extreme until both her savings and her partner's sperm are completely drained. This is an unprecedented, documentary-style production unlike anything seen in other works. A special, once-in-a-lifetime opportunity that you'll never forget—and can never experience again.
