"Just because."
The Miami heat was oppressive. It was wet and muggy they'd only gotten a reprieve from it while in the air-conditioned police station. They had hoped that when the sun went down it would be a little better, but now it was just dark, and wet, and muggy. To make matters worse, the air-conditioning in the hotel they were staying at had gone out the day before they got there and while hotel staff was 'working on it,' they didn't know when it would be running again.
When Emily and JJ had trudged up to their shared room after Hotch dismissed them from the station around one AM, the first thing JJ had done was open the window and the balcony door. The air that was circulating was thick and warm, but it was better than stagnant, stale heat. Exhausted, they had mechanically gone through their regular routine whenever they had to share a room: Emily using the bathroom first for the shower and to brush her teeth, and then JJ to do the same when Emily emerged to brush her hair, smiling tiredly as they passed each other.
JJ felt a little more alert after the coldest shower she could manage, sweat immediately prickling on her skin the second she stepped out of the bathroom. Emily was sitting on her bed, pictures of the five crime scenes scattered over the bedspread, determined to work until she couldn't keep her eyes open. Not in the mood to revisit the heat-bloated corpses of the victims, JJ all but flung herself onto her bed and closed her eyes.
"Is the light keeping you up?" Emily asked after hearing JJ let out a morose sigh, breaking the verbal silence between them for the first time since they'd gotten to the room.
"No, it's too hot to sleep." JJ groaned, standing up and stripping her bed of the blankets, leaving just the bed sheet and searching her toiletry bag for a hair tie. She tried not to notice Emily's eyes on her, but it was difficult when she kept wondering if they were thinking the same things. Emily had gotten ready for bed in her customary tank top, but rather than the loose pyjama pants she normally wore, she had opted for a pair of boy shorts, her long legs on display. JJ normally slept in something similar, a camisole and pyjama bottoms, but she had worn the pyjama bottoms for all of ten seconds before she decided it was too hot and just went with her underwear.
Neither one of them was showing any more skin than a one piece bathing suit would, but it was different now that they knew what each other's mouths tasted like, what each other's roaming hands felt like. They had both wanted to take things slowly despite what their bodies said. Had wanted to make sure they could do this, whatever it was, and still work together without compromising the team so they hadn't done anything beyond some intense make out sessions, but if those were anything to go by…JJ shook her head free of the thought and finally located a hair tie. She bent over slightly; tilting her head down so gravity could help her gather her long hair into a higher ponytail.
"Stop it." JJ chided, not turning around as she shoved her toiletry case back into her go-bag. "I can feel you staring at me lecherously."
"I'm not." Emily protested, sounding guilty before mumbling, "it's too hot anyway."
JJ turned and shuffled over to Emily, plucking the crime scene photo out of her loose grasp without looking at it and dropped it on the bed with the others, leaning down to kiss her. Emily's hands immediately went to JJ's hips as she half turned in her seat to get better access. They reluctantly pulled apart mere moments later, both a little red-faced from more than just the heat.
"Not that I'm complaining, but what was that for?" Emily asked, picking up the discarded picture as JJ tried to find a comfortable position on her bed.
"Just because." JJ stated simply, closing her eyes. "Don't stay up too late, Em."
"Goodnight."
