Re: 15th
With Stiles properly tucked against the tub, Derek adjusted the towel against his chest one last time before running his hand through Stiles' hair, urging him to rest his head against the towel too. "Nah," he said lightly, "I prefer putting all the restraints to good use." He preferred Stiles; an obedient slave wouldn't have filled any time outside of the times Derek would've wanted to fuck them. Stiles sucked up Derek's time and energy and it was exactly what he needed.
With the tub drained, he turned on the taps once more and let the tub fill up with hot water, adding more of the fragrant oils from before. Stiles was going to get punished but it was going to be separate of this ritual. As the water got higher, Derek cupped Stiles' hips and pulled them back, exposing Stiles' ass to the air. "Perfect. Just like that."
