[Tokyo Prominence Tomato] Business Sex Manners ~Training~ [Full Color]

Kaori-chan, a young office woman with long hair and a modest figure, takes her boyfriend and his burly partner Senpai out for what she calls a "business manners training" session—but the real curriculum quickly turns carnal as she's pulled into an improvised corporate threesome. Guided by her boyfriend's patient instructions and Senpai's commanding hands, she's coaxed into increasingly rough positions, from teasing handjobs on the couch to a full double penetration sandwiched between two muscular men. The title page teases the swinging premise, and the final author's note promises more "company manners" chapters ahead, leaving plenty of room for Kaori's on-the-job education to continue.
