Adam kept his eyes on Peter's face, watching each reaction as closely as he attended to what he was doing. His whole body was tense with want and need, tongue teasing again before he added suction, mouth fully taking Peter in. His fingers continued to tease their way back, stroking over Peter's skin until one could trace light circles around and over his hole, playing over the nerves there. He was a patient man, by experience and time if not nature, but he couldn't hold back the moan in the back of his throat at the taste of Peter on his tongue. Pausing for a moment, he slicked one finger before returning to his ministrations, letting his wet finger press gently against Peter's entrance.
