tickleback

Sexual act during which a female sits atop her partner (gender irrelevant, though originally adopted by partners of opposite sexes) who is on all fours, being ridden like a horse. The female stimulates her clitoris by gyrating upon the raised bumps of the spine.

Yeah, she went for a tickleback last night, my back was soaking.
