It needs to be massaged
From Create Your Own Story
You look at her making sure to maintain eye contact "Ok Grace you know when you have a sore muscle?'" You ask, with a sweet reassuring voice.
She nods "Yes my daddy pulled his back last summer and needed it to be rubbed out"
You smile wickedly "Oh good you do know what to do with a sore muscle." You put your hand on her shoulder "now when your daddy had his back rubbed was it dry or did you use a lubricant ?"
She replies:
dry (uh oh this could hurt)
he had me use a massage oil (ok this is starting to get good)
