Yussa bends one leg closer to his body and makes a soft sound as Caleb's tongue strokes more deliberately along slick folds. He can feel the shift and flex of muscles and tendons beneath his back; he can hear the scrape of claws on flagstone as the dragon moves restlessly.

None of it matters as Caleb's tongue - thicker and longer and shaped differently than Yussa is accustomed to - pushes into him. Yussa moans low in his chest, answering the deeper sound from Caleb as the dragon stops teasing. He arches closer, breath coming faster as his lover's thick, dexterous tongue coaxes his body to yield further, to accept the shape of him as it works in and out faster than Yussa thought it would be able to.

He mutters a few soft curses, voice strained and urgent. Soon he tries to meet the next thrust of Caleb's tongue, eyes nearly closed as he rides the new feeling. It isn't just the strength and shape of his tongue, but with every puff of breath electrical static crackles across Yussa's skin. It prickles over his nerves, not unpleasant.

"That's it," he whispers, offering encouragement even as his body gives Caleb plenty of positive feedback. "That's it, sweet boy."
