Sexual intercourse that's initiated by someone as a kindly or courteous gesture; a pity-fuck that's not gender-specific - term coined by Mark Hänser of Boston, MA.

Synonym: courtesy suck
The old queen was corpulent and years past his prime, but the young twink took pity upon him and, much to the old man's delight, gave him a courtesy fuck that caused him to squeal in porcine delight.
