Aimi works as a maid but frequently makes clumsy mistakes—breaking vases, sneaking snacks, or burning holes in her master's suit with the iron—leading to daily punishments. Wearing a collar, she is forced onto all fours, her hands bound, stripped of freedom and subjected to relentless torment, climaxing repeatedly. Each time, she pleads for forgiveness from her master. Aimi's honest and pure nature stands out even in these situations. Her innocence combined with the poignant vulnerability during punishment is the essence of this work's appeal.
