Lus' Punishment [28 Variants] (Pixiv Fanbox)

What a disappointment! After having failed so many sessions in a row, Lus’ trainer saw no other choice but to punish her. Now she finds herself stuck in a very uncomfortable position right in front of an empty frame in the dungeon’s main halls. For a week straight she’ll be left hanging as a beautiful part of the dungeon’s interior design with only small breaks to stretch, eat and rehydrate. Every orgasm she reaches during her punishment will extend her predicament by half a day though, so she might be in for a long ride~
