Xavier was happy that the sexy demon hadn't fought. He'd have had to pin the man to the ground if he had. He wanted to do this and wasn't used to being denied doing something he wanted to do. Especially not something sexual. He dragged his teeth over the flesh every time he pulled his mouth back up to the tip. Diving his mouth back down. Never did he stop sucking as he began to take the man down his throat. Sucking and tightening his throat around the tip. Pulling back up and bobbed his mouth up and down. Pulling up and dived his mouth down. Having all of the man in his mouth now. Sucking on him while licking the base. His hand still fondled the demon's balls. He trailed his tongue up and pressed against the flesh of the underside. His throat constricting and unconstricting around the penis that was down it. He made humming sounds to vibrate around the penis. Sucking and pulled up a bit and went back down. Bobbing his head up and down. Keeping his throat just a bit tight so it gave a tighter place for the penis to move in and out of. His teeth lightly pinching around the penis. He sucked on him like he was a lollipop of the best flavor. To Xavier the man tasted sinfully delicious and he hadn't even gotten pre or cum yet! He was eager to taste the man even further.
