Dylan's lips parted slightly at combination of the sight and feeling of Dave's mouth on his finger. He let out a small breath and briefly raised his eyes to the heavens in a vague thanks, then returned to eating his cake. "I should have birthdays more often, then." He said appreciatively, spearing another bite of cake with his fork to place it in his mouth. His appetite had been fairly good for a while now, since he was young and, yes, he shot up less often than Dave did. This was not a particularly difficult feat to accomplish. As he ate, he reached out his free hand to lightly stroke Dave's shoulder, and by the time his plate was clean, their chairs were almost completely pressed against each other from Dylan's moving. "Mm." He murmured, licking his last bit of frosting from his pinkie. He leaned over to rest his temple on Dave's shoulder, quickly sitting back up when the boniness of it led to him being uncomfortable. "So-" He began with a smile, "What are we going to do now?"
