At first Bilbo chuckled at the reaction he got from Thorin, then Bilbo's eyes widened at the king's words. Fili was the one who was spying on them? When Bilbo turned to look at the bushes, he ducked his head shyly at the moan he heard. He realized that the sounds he had heard earlier, the sound of metal, was the sound of Fili removing his pants to join in the pleasure, in a way. One hand threaded into Thorin's hair, he waited to see if Fili would come out of hiding like he hoped he would.<br/><br/>He rocked his hips against Thorin's lightly, trying to encourage Fill to come out by the soft moan that escaped his own lips. "Please Fili... he is right... I would like you to come and join us." He looked back at the bushes, the look on his face almost pleading.
