This was cute, although I get kind of confused in group sex scenes so I skimmed those parts. But I liked the premise ("What if all of Santa's reindeer are shifters who have kinky sex when they're in human form?"), I like beardy older guys, and I liked philosophies like "I made a noise behind my gag and, with a wink of his eye, I knew I had nothing to dread. Whatever evil thing he had planned, he meant for me to enjoy all of it."
The author was SUPER creative in a hilarious way about making all the accoutrements of Christmas fit with a kinky story -- smacking people with candy canes that burn in a pepperminty way when they hit your skin, toys that look like icicles, being tied up with garland, etc.
