I have some experience with anal fist (as the bottom) and although I haven't tried this particular technique, it makes some sense to me. We're not talking about punching someone full force, we're talking a few light (but firm) taps. For the receiver, it's probably a similar sensation to...I don't know what it's called, but that form of massage that involves "hitting" the patient with a rapid chopping motion of the hand. From this description, I don't think it even qualifies as light S&M...
