A latex girl thing

He turned, but stopped when he spotted an oddity he missed behind the door. Rusty slowly closed the door; something partially covered under a drop cloth. When the door closed enough it pulled the rest of the drop cloth off, revealing an oil drum. It was very old, rusty; it was black once based on its remaining paint. Part of it was burnt. What caught his eye prior to its reveal was the white, faded Asian writing on it; Slave did look a bit Asian in her eyes, although she didn’t sound foreign. Now looking at it fully, he saw there was some German there, too. It read clearly:

WARNUNG: EINE GUMMIMÄDCHENSACHE!

“Gummi? ‘Rubber’, I know that one,” mused Rusty. He only did because he knew some of the foreign vernaculars in bondage and fetish from visiting foreign online stores; his wife just adored DeMask. In fact his wife was learning German, just so she could sound like a German dominatrix next time they played.

Rusty read it some more and mumbled to himself, “’Eine’… ‘A’, I think.” He figured the first part was ‘Warning’ because of the ‘W’ and the exclamation point at the end. Beyond that, the rest of it made no sense to him; they weren’t German fetish words. He made a note to ask his wife, so he repeated the word silently over and over until he felt he got the gist of it. He would just tell her he got curious about German phrases, done an online search, and came up with it.
