Something that sounded like mmmhmm came from Harry, but it was garbled. Theo’s hands rested on the back of Harry’s head but let him set the pace. The tip of his tongue swirled over the head before he hollowed his cheeks and sucked hard, unexpectedly, making Theo’s legs quake for a moment. Harry felt the quiver of his thighs in his hands and grinned while he worked his way up and down, slow at first before building up his pace, occasionally tossing enamored glances up at Theo.
