Manami, a beautiful big-breasted office lady in her second year of work after graduating college, handles route sales at the Tokyo branch of a major sake brewery headquartered in Kansai. Passionate about drinking, she struggles to support her nightlife habits on her salary alone, so she secretly seeks financial sponsors who can assist her—exclusively during lunch breaks. Using social media to meet men, Manami openly pursues both money and sex. She frees her ample breasts from her suit and greedily sucks cock with her filthy mouth. She's repeatedly brought to orgasm with toy play, revels in pleasure during bareback penetration, and doesn't mind granting permission to cum—for an extra fee. The men who satisfy her desires soon become an exciting part of her daily sales route.
