Keeping her mouth shut tight so that she didn't let out a scream, Rachel writhed in sweetest pleasure, bouncing around in Luna's grasp and shaking with ever-growing pleasure.  Her hands started fighting, wanting to start using her hands, even on herself if she didn't know which parts of a werewolf to pleasure properly.  More and more of her juices flowed as the need kept on building, but this time, not caused purely by the pheromones.  It was a perfectly natural reaction to so much bliss that she wouldn't want it to stop until she could have a proper orgasm.
