Riley felt his heart begin to race every time Tao's lips brushed over his neck now. It was instinctive, and he didn't bother trying to repress it. He felt more than hot enough for the two of them as he continued to stroke Tao, taking his hand away from the vampire's face to take himself in hand, as well. He didn't bother to reply to what Tao had said, instead he just responded in kind to the vampire's actions with lips and tongue. His kiss became slightly more desperate as he positioned himself at Tao's enterance, and quickly deteriorated into a groan of pleasure as he plunged inside the other man's body.
