"Master, please train us..." begs Hikari and Hana, undergoing their first double training session. Filled with tension, shame, and rivalry, the two strip each other naked and kneel in seiza, waiting completely bare for their Master's arrival. Even as their heads are trampled under his shoes, they instinctively grind their hips in arousal. They masturbate side by side, cooperate using their breasts to pleasure him, and obediently let him fondle their tits and underwear according to his desires. Their big tits exist solely to satisfy the man's pleasure.
