Lexeo wasn't weak willed. He had just very quickly weighed the pros and cons to each action. The action with less consequences was to do the blow job. He growls at him. Glaring at him. He would argue with him about the taking him part later. Along with the bjs from him part. Scowling a bit. Taking the hard cock into his mouth. Sucking and nipped lightly. Making sure his displeasure at the draining comment was heard. Gasping as he moved his mouth up and down experimentally. Sucking a bit as his tongue trail up and down the underside. Moving his mouth with a soft sunctioning type action. Trying to make the vampire have pleasure and to get his mind off of his blood. He sure as hell was not following any commands given by some vampire. Even if the guy was more dominate than him. He was not weak willed just played the game by what was the strongest of emotions.
