In the dim, candlelit chamber, the air thick with anticipation, the master's hand grips the bamboo cane, the '打屁股' (da pi gu) glistening with a thin coat of wax. The slave, bound and bare, awaits the first strike. The '藤條' (teng tiao) sings through the air, landing with a sharp crack across the slave's ass. The boy gasps, his body tensing, but he holds his position, ready for the next 'hard caning'. The master admires the red welts appearing on the slave's skin, his own arousal evident.
