Boone bites his lip as his hand starts to move, huffing as Uldren bites at his neck. He feels the tension in Uldren's body, the way his hips twitch, and knowing that he's the cause for it is... unbelievably hot.

He teases at first, his stroking slow and pointed. But soon it speeds up, and he encourages Uldren's biting by grabbing at his hair again and letting out a soft sigh. Not quite a moan, but loud enough to be heard. He can feel his hand brushing over his own cock as he moves it and has to move his hand slightly for fear of actually making himself come by accident.

He realises he's going to be a mess after this. He doesn't care. If anything, in this haze of lust, the idea of Uldren coming on him makes him squirm. He moves his hand faster, aching for Uldren to touch him again but knowing he's too close to last for long. It'll be over within the minute after Uldren decides to continue.
