This character gets washed by another character. Apply i1938 to the performing character.
A Bodysponge is someone, mostly a woman, who uses their body to wash, usually (but not limited to) the back, of another character. This creates friction which may or may not lead to i1826. Can also result from (or to) sexual tension or as a form of gratitude.
Do not confuse with i1889, which refers to macrophillia, whereas here both are normal-sized.
