I'm a little stuck... Click here to teach me more about this clue!

'rubber' is the definition.
(I've seen this in another clue)

I cannot understand how the remainder of the clue works.

(Other definitions for masseuse that I've seen before include "Manipulator of body" , "She kneads bodies" , "Uses same sort of woman who kneads muscles to lessen stiffness" , "Uses seam (anag)" , "Female rubber?" .)

I've seen this clue in The Guardian.
