A man who keeps too many submissive big-breasted female slaves. Among them is a college student named "Hono" who is thought to be plain and quiet by those around her. Another is "Hazuki," an overstressed office lady working in accounting at a trading company. This time, he summons these two for simultaneous training play. Since all the play is done with both women at once, they engage in double kissing, double fellatio, double paizuri, double genitals play, and then motorcycle sex, all while using their large breasts to serve.
