The latest installment in the Hikari Chou M series, the fifth release, features lewd sisters dressed in nurse uniforms indulging in lesbian play. When an M man suddenly appears, a forced health examination begins. A relentless series of torments unfolds—spanking, facial riding, handjob, footjob—with pleasure continuing nonstop until he's completely knocked out. This work fully captures the sisters' depraved nature and their obsessive fixation on the M man.
