No one had sounded that pleased to be allowed to kiss him before. People had rarely asked for permission at all and when they did come to him with need it wasn't like this, like his body was a privelege but like they'd finally found somewhere to get off and then leave. Aster's kiss was as sweet and honest as the boy himself and Timothy murmured back in answer to the sounds coming from Aster, a little more groany when Aster's fingers pushed back into his hair and his tail tip flicking once, twice against Aster's hip and then winding down around Aster's leg. Timothy instinctively but tentatively opened his mouth to let Aster deepen the kiss if he wanted to, a little signal that he was happy to go further if Aster wished.
