There wasn't another incident until a few days later.
They didn't really formally discuss what had happened between them, other than the one night in the bathroom. But, something had still shifted. For the better, in Jack's opinion. It felt like they had gotten closer, like he could be more open. They shared a bed each night instead of most nights. They didn't have any more physical intimacy passed cuddling, which was normal, but it still felt better somehow.
Jack wanted to breach the subject again, wanted to push for something.
Jack wanted to be bold; it had been days, but he wasn't courageous enough to start a verbal conversation. He wanted to do something physical, to provoke a reaction out of Gabriel, to know the man still felt the same about what this was.
He had an opportunity after training, when Gabriel had made a detour into the restroom. Jack followed him but before he could position himself at a urinal he had tugged on his wrist, "Gabe." He had said, gesturing towards a stall, a little anxious about it since no one was in there yet but surely someone would come if they weren't quick.
Gabriel hadn't fussed or even gave him any sort of look, just followed the blond into the bathroom stall, "I do really have to piss though." He said, a little like a joke, his tone light.
"I know," He said, still feeling the nerves getting to him as he sat down on the toilet in front of the other man, "I just, can I?"
Despite Jack not really giving him much to go on Gabriel said, "You can do anything you want Jackie." With such an ease of conviction that it caused the blond to flush.
Instead of trying to puzzle out the sentence, he worked on unlatching Gabriel's belt, popping the button on his fatigues and slowly pulling down the zipper. The man above him interested in what was going on, but Jack could hardly look at him. Despite being accepted for his unusual needs, the fact that nothing had really been discussed in terms of boundaries or even what they were still had him a little on edge that he might push too far and it'd all break apart.
When Gabriel brushed his knuckles against the side of his cheek, down his jaw, the action so tender it made Jack's hands shake as he tugged down his underwear and finally freed his flaccid cock. Gabriel widened his stance and Jack gently ran his hands along his soft shaft, "Can I?" He asked again, even though he knew he didn't have to.
It finally seemed to click for Gabriel though, he raised a brow but didn't offer any further skepticism, "Whatever you like sunshine."
Jack took the incentive to lean forward, to finally take Gabriel's dick into his mouth, just pillowing it against his tongue and enjoying the salty flavor of him. Sweat from training mixed with the precum that beaded at the tip of it.
One of Gabriel's hands found his hair, nails raking over his scalp, sometimes gripping his hair before letting it go again. Just aimless movement as he relaxed his body and tipped his head back, giving the blond what he wanted.
The first spurt of piss was released in his mouth and Jack closed his eyes; moaning deep at the warm acrid flavor of it. Encouraging without words for the other man to keep letting go; having placed his hands on Gabriel's strong thighs, his fingers digging into the muscle as the other man continued to piss.
Stronger this time, and Jack was swallowing every drop, feeling his cock grow hard in his pants, having to adjust with a squirm on the hard toilet seat.
"You're really into this shit, goddamn." Gabriel said, a little breathless, the warm cavern of Jack's mouth sucking him down while he urinated was definitely something he had never experienced before. It was a strange sensation, but definitely a good strange. He could definitely get used to it, if this was what Jack wanted.
Eventually the stream stopped; there was nothing left to suck down but Jack licked at him anyway, cleaning him up and keeping him in his mouth.
Gabriel groaned, just a deep rumble of sound above him as he gently pulled on Jack's hair, "If you keep doing that you'll have something new to swallow."
Jack just gave a hum, not stopping, his body pitching forward a little more; inviting, wanting, even without words. His eyes were closed, completely enraptured by the moment, unable to stop. Not wanting to stop, the hands on Gabriel's thighs moving up to his hips, running under his shirt to run his nails over his ribs.
"Fuck." Gabriel hissed at the sensation, already feeling himself grow hard under the soft warmth of Jack's tongue and hot mouth. Wouldn't be long before he had a full erection, his hips starting to move as he thrust in and out of Jack's mouth.
Jack relaxed his throat, took all of it in, right to the root, his nose buried in Gabriel's pubic hair. The masculine smell of him turning Jack on even more; but his own 'problem' wasn't even an issue. He was completely focused on what he was doing, wanting to get Gabriel off, completely singular in his need.
"You look so fucking good on my cock." Gabriel panted, his hand having moved to the back of Jack's head, tipping it back a little, letting him push in easier. Controlling the pace, his brown eyes blown, teeth biting at his lower lip.
Jack looked up at him then, blue eyes rimmed with tears, faced flushed in effort as he was used.
It was at that moment the bathroom door opened; a duo of soldiers walking in, chatting amongst themselves. Loud enough to break the moment.
It was also exactly at that time that Gabriel sucked in air and jerked his hips to crush Jack against him as he came down his throat.
The blond's throat convulsed around him in quiet dry heaves, nails digging into his hips but he didn't stop and Jack didn't try and push off. Suffocating on him so, so good.
It took less than a minute for him to pull himself out and for Jack to grab in air, his lips swollen and red, his eyes still glassy and far away.
He reached silently down, running his calloused fingers over the bottom of his lip. Gabriel leaned in, the sound of the soldiers in the bathroom of no real consequence, but still a threat. His lips pressed against Jack's ear, "You're really something else Morrison. Gives a new meaning to the nickname 'golden boy', doesn't it?" He joked before he kissed the side of Jack's face, tucked himself away and left the cramped stall.
Jack was left dumbfounded in the wake of the innocent kiss; not even bothered by all the dirty shit that just happened. Or even the fact he needed to wait until the other soldiers left before he could even leave the stall.
He'd probably be late for drills, but even that was a distant worry.
Gabriel had kissed him. He'd never done that before.
