Book 4 in the Mistletoe Magic series, but may be read as a stand-alone story
When three of Santa's elves were ordered to provide happily ever afters for the Woodward sisters, they promised themselves a celebration if they were successful. Sharing a motel room during their assignment created a whole new level of sexual awareness among them, where boundaries were breaking down mentally day by day. With arousal at its peak after they all succeed, they decide to indulge in a sexual game of Truth or Dare, which will give a whole new slant to their friendship and allow them to explore their darkest fantasies—maybe even love.
