[His arms strain at the ropes holding them back. Those knots were better than he previously indicated. So, instead he just experimentally arches himself trying to go deeper into Jack's warm, wet mouth without choking him. He isn't exactly letting go yet, just testing the waters and damn the water is good.]
[Even if he couldn't feel all of this—and he can—he'd still be turned on to the point of bursting just by imagining the way Jack looks as he attacks him. He wishes he could see those lips and hollow cheeks.] I'm going to need more training. [So much more of this! But probably not today because he's never going to last with the way Jack is swallowing him down.]
