A man arranges casual sex with a woman from a secret social-media account, only to discover she is his serious coworker Yamagishi. Instead of leaving after the awkward reveal, she takes him to a hotel and unleashes her hidden appetite. She licks him all over, rides his cock hard with her big ass, takes a creampie, then drains more cum and swallows it. Their secret arrangement expands to golden-shower cunnilingus, watching her masturbate, stealth blowjobs, and overtime creampie sex. Because she is discreet and reserved at work, she becomes the perfectly convenient fuck buddy.
