"Sombra+meu+marido+quer+ser+corno+vol+18+work" translates to "Shadow+my+husband+wants+to+be+corn+vol+18+work". Wait, "corno" is Portuguese for "horn" or "corno" as slang for a cuckold in some contexts. "Vol" might be short for volume or a publication. "18" could indicate age restriction or part of a title.
