[Asakura Mitsuru] Nico Nico Women's Prison (ANGEL Club 2016-05) {Hennojin}

Block No. 69 of a certain women's prison has zero interest in rehabilitation — its mustachioed warden gleefully declares it a meat toilet-raising facility where busty convicts are forced to service the staff as part of their daily work. Strung up in tight shibari and fitted with collars, the sweat-soaked inmates are worked over by machines and guards alike, their sobbed pleas to stop melting into shameless begging as their minds break one climax at a time. Fully reformed into erotic maid servants, they end up gagged, collared, and eagerly begging for more.
