Well, here's a challenge a cock that knows me oh so well... to the point that he claimed he could hold out & resist my oral skill's? He could keep control whilst I chewed & licked his balls... whilst I ran my tongue up and down his whole length... keep it together whilst I chewed and nibbled his skin (you know the 1)... he did till I got control of his balls to make sure he splashed high up for me to see & of course clean him up.
