Fili was paralyzed staring at Bilbo's naked back, forcing his breathing to stay quiet. He quickly analyzed Thorin's words, and realized that his uncle knew he was watching them, he didnt knew what to do, should he step in and join them, or stay where he was? He surely wasn't going to go back to the camp.<br/>His body was getting tired from the forced position and he needed to loose his pants, his trapped cock began to ache slightly and he felt the need to stroke it. Controlling his moves he slowly took a hand down to his belt buckle, fighting for a moment to get it open, and unbuttoned his pants letting his member out. With his eyes fixed on Bilbo he began to stroke his cock, trying not to make a sound, even knowing he had been spotted already.
