I found these pictures on alt. binaries. pictures. erotica. bondage without any context. Being very sedate and devoid of nudity, they look almost like they could be real scenes from an Asian prison setting, rather than the stills from some jailed girl sexploitation movie that they probably are. But note how gleamingly clean the place is — for sure, no American penal facility looks like that.
If anyone knows the source, by all means share in the comments!
