Jack was afraid of being found out.
So afraid that he avoided Gabriel when the man went to piss, made sure he used the bathroom either before or after he did. Sometimes when that didn't work, he was sure to use a stall instead, or wait for one.
If Gabriel had noticed the avoiding behavior, he hadn't said anything about it, and everything continued on as normal.
As normal as they could be, now that Jack couldn't get the mental image out of his head, nor could he stop fantasizing about his best friend.
It didn't help they shared a bed most nights; but Jack was quick to rise, and first to sleep.
He didn't want things becoming awkward, and he felt like he had a sign on his head that said 'I want to be fucked and pissed on by Gabriel Reyes'.
Jack had felt he had been so careful, kept up normal appearances as much as he could, that when Gabriel started pissing in the showers Jack almost choked.
The room was empty, just the two of them, but that didn't mean anybody couldn't walk in at any time. They had just finished a round of sparring, a relief to Jack's pent up frustrations, and the heat of the showers had started to break the tension left in his body. The steam had felt good in his lungs before, but now he felt like he couldn't get enough air.
Gabriel had his head tipped back, his hands in his lathered hair; massaging his own scalp as his feet remained firmly planted apart. His body looked longer this way, so casual in his posture that the moan from his lips was almost obscene as his cock twitched to life as he began to urinate not a foot away from Jack in the communal stall.
"Gabriel." Jack blurted out before he could stop himself, his voice something of a hiss, almost accusatory as if the man knew what he was doing to him.
Of course his senior officer didn't pick up on the scandalized tone, or if he did, he didn't comment on it. He just kept running his fingers through his hair, then down his neck, continuing his business as if nothing was wrong(and really, nothing was wrong except the way Jack was reacting), "Saves water. I'm not going to get out and walk all the way to the bathroom and back soaking wet."
Logical, to the point, as Gabriel normally was.
Jack bit his lower lip, glad the water was hot, it meant the extra flush on his skin didn't appear abnormal. He wanted to look away but he couldn't, not until finally Gabriel had finished, his blue eyes looking up that strong body with a deeper hunger than before.
Gabriel was looking at him, one scarred brow raised, "Got a problem with it?"
He swallowed, turning to busy himself with shampoo, but mostly giving Gabriel his back so he wouldn't see his 'problem', "Nope." He said flatly, thinking this man was going to be the death of him.
