Yes, great squirting orgasms! You'll notice though it not the fisting so much that makes them come so hard they squirt. It's the fingers up and in to the G spot especially if the heal of the hands hits the clit at the same time. My mature wife comes and projectile squirts for hours (especially if in one of her naughty hotel meetings with her FWB and what she dlls his magic fingers) if properly stimulated this way - her pussy is too deliciously tight for fisting.
