Riley's entire body shuddered when he felt Tao tremble under him. Warmth spread over his stomach and he groaned, coming just a few seconds later. His grip on the vampire loosened and he shifted to his side, wrapping his arms around Tao's waist. He made no attempted to pull from his body, instead held close, resting his head on the vampire's chest. His entire torso heaved, and he could tell that his skin was flushed. "Sorry." He panted, raising one of Tao's hands to his lips to press a gentle kiss to it. "Sorry." He murmured again, nuzzling his forehead into the crook of the vampire's neck.
