Without really warning him, Tony slowly started to move within him, distracting Steve with kisses and stroking his cock. "I'm going to come inside of you so deep," he murmured against his lips as he trailed his lips down his neck, his hand burying in his hair and tilting his head back to give him better access to his throat. He sucked on his Adam's apple, letting his tongue run around the spot before moving up. "God, you're so tight...gonna make me come soon..." Then he leaned up off of him and braced his hands on Steve's hips so he could watch his cock slid in and out of his ass, making sure not to push himself all the way in.
