Gibbs knew it was wrong to assume something important, especially about the people he really cared for. Or maybe it wasn't actually an assumption, maybe he'd just forgotten about it, about what they looked like beneath the badge and the clothes, though that had never defined anything about the person they were. The only thing that had hinted Gibbs to anything physical was when he'd first seen their chest. He couldn't remember if they had been changing in the locker room or needed tending to after an injury they'd received. The details didn't matter much, but that was the first time he'd ever had questions and asked them outright. Questions that had most likely sounded offensive or disinterested, and yet they had taken their time to answer them, to explain it all. It was a given that Gibbs could've missed any length of their explanation, their descriptions of themself. He was more focused on the way they confided in him like it was the simplest thing in the world. Gibbs had just gotten used to it that way. Getting to know them, who they were, how they felt about themself and him. They trusted him thoroughly, and he was proud of that fact.

That's why seeing them beneath him, bare naked with their thighs spread beneath his calloused hands, with a cunt and a t-dick to match shouldn't have been the surprise it felt like. Gibbs had been preparing himself for this moment their whole relationship - if that's what they considered it - but nothing could've prepared him for this. For the shameless arousal that had thick desire sinking and settling in his stomach, his eyes falling shut as he forced himself to breathe. For a guy his age, he couldn't believe how inexperienced he felt. What he should've felt was that they were far out of his league and arguably too young to be doing this. Any of this, with any of him.

But they'd already gone too far. More specifically, Gibbs had gone too far, and he knew it. Breaking his own rules, chasing after them, and it was already too late. He was already leaning down, brushing his lips across their collarbone and up their neck, even as he churned the revelation over in his head. He was sure they might've already gotten bottom surgery, changes beyond hormone replacement, but they hadn't. Of course, he could live with that just as he could with everything else about them, it was just a little different than the expectation.

"You're handsome," Gibbs told them, puffing out an unsteady breath over their skin, almost as reluctant as to make eye contact as they were. He did anyways, bringing a hand to tilt their chin forward to lock eyes with them. "You know that?"
