At least I think, it's been so long but I think it was yuri? Some woman gets turned into a box and put into a horrific torture of…cumming? Stimulation for a month? Some 'I have no mouth but I must scream' type shit. For the life of me I know it exists somewhere but cannot find it no matter how much I search.. I think the evil woman/thing wanted a sacrifice in order to not kill people? Sorry for vagueness my memory is bad
