Abrasion (sensation play)
Where the top is manipulating the sensations experienced by their bottom, abrasion is one way they can do this. This may be done by rubbing or scraping the target portion of the body with sandpaper, coarse cloth, fingernails or other objects.
Abrasion causes or can compound tenderness. This tenderness can persist for hours or days. For some people this can serve as a reminder of pleasant times recently past.
