Obi-Wan is aging surprisingly well (obi1) wrote in valarlogs,
What Loras definitely saw upon entering was a frantic splash of water, as Obi-Wan snatched a washcloth from the side of the tub and fashioned what could only be described as a makeshift loincloth for himself. It was an impulse decision, with no critical thinking or analysis behind it. Basically, his brainstem had acted on its own: Naked = Cover Self; like Adam, in the Bible. At worst, he felt foolish for not locking the door.
What Obi saw was Loras in all his glory, for about two seconds. And while it failed to excite him, the surprise in and of itself was enough to leave him wide-eyed and without breath for a minute or two.
The curtain was drawn and the sounds of the "piss" Loras had warned of followed. Obi released his grip on the washcloth and took a long breath to settle himself. He could not help but feel, especially now, that he was some kind of invader or interloper in Loras's world. He even felt the urge to apologize for being in the bathroom at all.
Obi held his breath and dipped his head beneath the water again. He brushed back his hair. Loras was still peeing. God, that was taking a while, wasn't it? From behind the curtain, he lifted an eyebrow. "Well, good to know you're getting plenty of fluids." And then, the not so smooth shift into, "Sorry. Should have locked the door."
