Signature and text on hand drawn shunga (shibari.)

[Ger]

Please read what might be a signature on one of a set of hand drawn shunga. Mainly shibari.
Not knowing what is allowed to show, I only attach here the top right corner.

An other drawing from the same set, the only other one with text at all, has quite a story.
If it is too long for a full translation please give an idea of its content - especially where it might help with the age of the drawing, or the identity of the artist.

The two characters say 落城 (fall of the castle). It normally doesn't have any erotic connotation, but in the context of that picture I guess it refers to the fall of that woman's final defenses.

The other writing is some erotica - would take a while to decipher it.

That image 落城 shows several men taking advantage of captured women - from the fallen castle I presume...
落城 is not used as a persons name?

 

[Majestic]

No, Rakujō would not be a person's name.

Unfortunately, there's no such information. Judging from the writing style, I don't think it's in Edo period or older.
