This provocative, playfully contrarian side of Yussa is one that Caleb has rarely seen before tonight--perhaps not ever, really. It almost feels like a test, as though he is intentionally presenting a challenge for Caleb each time he waits for direction or demands specificity, prompting him to practice reinforcing his control.

That direction was fairly clear, he thought, but he doesn't have any complaints about watching Yussa present himself on his hands and knees, demonstrating one pose, then another for comparison.

"Hm. Let me see." Caleb remains warm, but impartial, as though he really is considering his options as he leaves the plug by his knee, within easy reach, and runs a broad hand down along Yussa's right flank. Swift and abrupt, he pulls it back a short distance, and his palm connects with a resounding crack across the right side of Yussa's ass, just sharp enough to make his hand smart.

That impulsive choice comes with a spike of adrenaline so strong it makes him momentarily dizzy. Now his pulse is pounding.

"Ja, this will do nicely, if you can maintain it," he says, distantly impressed by his own ability to feign disaffection. But it's far from the first time tonight he's followed through on the urge to spank Yussa, is it? "Do not move."
