Justin Bieber gets excited talking about his male friends. At 10 seconds in his dick jumps, at 11 seconds it jumps again. At 12 seconds he covers it with his hands. At 15 seconds he looks down at it, trying to see if his hard on is showing. And at 17 seconds he puts his leg up to cover the entire area just incase his little man decided to stand up even more. Needless to say, him and his male friends must have a lot of fun when no one is watching.
