Loki didn't know which sound was more beautiful; the resounding crack on her pert bottom or her sharp cry of both pain and pleasure. Either way, it spurred him onward and after a brief second where he massaged the spot where his hand had landed, he lifted it and prepared to go again. Again and again, and again he let his hand land upon her naked arse, turning the flesh from pink to smarting red. The color was exquisite just as her continued whimpers, cries, and gasps were like music to his ears.
