In the dimly lit dungeon, the master's heavy boots echo as he circles his bound, naked slave, his eyes gleaming with anticipation. The slave, already hard and eager, whimpers as the master runs a gloved hand over his body, pinching and twisting his nipples, before pulling out a whip. The sound of leather cutting through the air sends shivers down the slave's spine, and he braces himself, crying out as the first lash lands. His ass, already pink, bears the welts proudly as the master continues, alternating between pleasure and pain, until the slave is a quivering, desperate mess, begging for his master's cock.
