Who among the three will be chosen by the 'Reika' queen, who is beautiful and has beautiful legs? The M slaves who raise their voices to the queen's excellent play techniques of bondage, candles, and whips. They remember the smell and feel of being stepped on and turned into a chair with those beautiful legs. The queen, who simultaneously anally trains the two slaves who have been narrowed down, skillfully loosens their anuses and overwhelms them with pleasure! The M slave who remains until the end raises a 'good sound' and is rewarded with the long-awaited penis, writhing in pleasure!
