Predator... or Prey? (Elsanna同人短篇）(6)

Anna squealed at the pain but stopped herself as she felt the pain transformed to pleasure, sharp and fierce but definitely enjoyable. "H...how?"
"I told you. Now sit back and enjoy the punishment." With the swipe of her arm Elsa's white gown faded to crystals, rewarding Anna with a beautiful sight. "Naughty girls deserve punishments, and aren't you the naughtiest among all our family?" She teased.
“Elsa wait, I... argh!” Anna’s unfinished words twisted to a groan as more icy blades sank into her back. But right before the pain gets unbearable it shifted to a softer sensation, as if hundreds of tiny hands massaging her back with pinpoint precision, chilling yet stimulating pinches that passed along the nerves in her back to the head then shot straight down, flooding her canal. The redhead flung her head back with a gasp, overwhelmed by such sudden rush of pleasure. And like the collapsing dam destroyed by earth giant’s boulders, her canal shuddered and convulsed, ejecting streams of love juice.
