Pairing: JJ/Hotch

Song: I'm Your Man by Michael Bublé

And if you want a father for your child
Or only want to walk with me a while
Cross the sands
I'm your man

"'Otch and Jack Jack!" Aaron smiled at the tiny little guy in his mother's arms, reaching out to give Henry a poke in the belly. Henry immediately dissolved into laughter as JJ sighed heavily, shaking her head as she opened the door fully so Aaron could actually enter her apartment.

"I swear to God you're a lifesaver Aaron. I'm sorry to call so late, but Henry is refusing to go to sleep and he just keeps repeating 'Otch! 'Otch! over and over again and he just gets so upset when I try to put him down-"

"Jack Jack?" All of Henry's focus was on Aaron, who now stood in JJ's living room after shutting the door to her apartment. His attention was divided between the adorable boy and the beautiful woman in the room with him. Aaron shook his head, his attention back on Henry.

"Sorry pal. No Jack tonight." Henry's face fell a little and he pouted, pushing his face into his mom's neck. JJ adjusted the boy in her arms, her brow expressing the confusion at Jack's whereabouts. "He's over at a friend's house for the night." He walked further into the apartment, a small smile on his face as he passed close by JJ. "I told you it was no big deal for you to call."

JJ blushed, returning the smile as she followed him into her apartment. Her heart jumped a little at how easily he maneuvered around her apartment, putting his jacket in the closet; he fit so well at her place, just as she did at his place. After Haley's horrific death and Will abandoning his family to return to New Orleans, the two single-parents instantly bonded and connected with each other, forming a friendship that gave them both strength, support, and happiness. A friendship that was quickly becoming a relationship that surpassed the simplicity they had started with originally; their current relationship was swiftly turning into something neither one had any desire to fight against.

The little boy in JJ's arms made a small noise, something between a whimper and a sigh. JJ bounced the boy on her hip as Aaron walked back over to the pair, leaning down slightly so he could gaze at Henry. "How's my pal doing tonight, huh?" He ran his hand through the small boy's hair before Henry's head snapped up to stare at whoever was touching him.

A huge smile erupted on Henry's face; it was almost as if he had forgotten Aaron was there. "'Otch! 'Otch!" He clapped his hands together, causing both of the adults to laugh. Henry began to lean towards Aaron and JJ had to tighten her grip on her son so he wouldn't go spilling out of her arms.

Aaron automatically and instinctively reached forward, taking the small boy in his arms. "Hey pal. You need to get to bed little guy."

Henry shook his head. "No bed. 'Otch!"

Aaron gave Henry his 'childproof' glare, holding the small boy against him with one arm. "No bed huh? You know what I do with little boys who don't want to go to bed when it's their bed time?" Henry's face lit up with a huge smile as a small giggle escaped his lips. Aaron continued staring at the small boy, his face stern but obviously amused by the whole situation. He raised his hand and wiggled his fingers as Henry continued to giggle. "I…TICKLE THEM!"

Aaron's hand connected with Henry's belly, tickling the poor boy relentlessly as Henry erupted with laughter. Aaron began laughing with Henry as his tickle assault continued, Henry wiggling all around in Aaron's arms as he howled with laughter.

JJ watched from afar as two of the three most important boys in her life laughed and played together; the only thing missing from the perfect moment was Jack. Eventually Aaron's assault ceased and both of the boys calmed down as Aaron bounced the boy in his arms for a few moments before looking at him seriously. "You ready for bed Henry?"

Henry clapped his hands and looked over at his mom, pointing to her as he turned back to Aaron. "Mommy."

Aaron nodded, a small chuckle escaping his lips. "Yes Henry, that's your mommy."

Henry laughed, obviously very pleased with himself for pointing out his mom to Aaron. He turned to Aaron and pointed to him, his little finger connecting with Aaron's chest. "'Otch."

Aaron nodded once again. "Yes Henry, I'm Hotch."

Henry nodded, his face turning serious. "'Otch. Daddy."

JJ froze, her body tensing up at her son's words; Aaron's body remained relaxed but his face was covered with a shocked expression. "No Henry, I'm Hotch."

Henry nodded, a very serious look still on his face as he stared at Aaron. "'Otch. Daddy."

JJ couldn't stop the gasp that escaped her. She didn't know how to handle the situation at hand. Henry associated the words 'Hotch' with 'daddy': her son saw Aaron as his father.

Aaron miraculously stayed calm as he stared at his co-worker's son who had just called him daddy. He smiled at the small boy as he pointed to Henry, his own finger poking Henry's belly, causing the little guy to giggle. "Henry."

Henry clapped and pointed to himself. "Henry!"

Aaron laughed. "Yes, you're Henry. And it's time for Henry to go to bed."

Henry clapped again and nodded. "Bed." He reached out for his mom; thankfully JJ had recovered enough to reach out and take her son as Aaron passed him over. Henry yawned loudly and laid his head against his mom's shoulder, his face turned towards Aaron.

"Bye bye 'Otch."

Aaron leaned over and gave the small boy a kiss on the cheek. "Good night Henry." He turned to look at JJ, his face becoming more serious. "Do you want me to stay?"

JJ nodded, unable to come up with what to say. Aaron just nodded and walked over to the couch, calmly waiting for JJ as she put her son to bed. She took Henry into his room where the small boy fell asleep the moment his head hit his pillow. JJ smiled at her little man, leaning down to give him a kiss before exiting the room. She took a deep breath as she saw Aaron still seated on the couch before walking over to sit beside him. Aaron smiled as she adjusted herself beside him, and JJ did her best to return the gesture.

"Aaron I'm really sorry about that. He's never done that before, I didn't even know he thought that. I know with Will being in New Orleans that Henry doesn't really see his dad but I had no idea he came to associate you with his dad."

"JJ, are you uncomfortable with what Henry said?"

JJ paused, confused by Aaron's question. If anyone had any right to be uncomfortable it was Aaron, not her. Aaron instantly knew JJ was taken back by his question, so he shifted on the couch, his body angled closer to hers. "Are you uncomfortable that Henry just called me his dad?"

JJ took a moment, staring at the man in front of her, the man she had honestly loved for years longer than she should have. JJ was no fool; her crush on Aaron started the moment she met him all those years ago when she first joined the BAU, and those feelings did nothing but intensify and grow over the years. The past year had somehow managed to solidify those feelings even more as their relationship began to change, and JJ couldn't deny that she had dreamed more than once about Henry being Aaron's son instead of Will's. Unable to actually utter the words out loud, JJ simply shook her head no in response to Aaron's question.

Aaron started smiling the moment JJ shook her head, his joy totally surprising JJ. "Then we're in agreement. So don't worry about it, ok?" JJ simply marveled at the man before her, unable to fight her awe and admiration for him, before leaning forward to press her lips firmly against his. Even though she immediately realized the severity of her actions and pulled away almost as soon as their lips touched, neither one of them could ignore just how perfectly their lips had connected after only one tiny touch.

JJ sat back, her eyes wide open in shock at her outrageous behavior. "I'm so sorry Aaron, I honestly have no idea what the hell I just did-"

Aaron leaned forward, effectively cutting JJ off as he kissed her, his hands moving to hold her face, his thumbs rubbing against her cheeks. JJ tensed for one single moment before melting against Aaron, her own hands reaching up to rest against his chest, curling into his shirt to hold him against her. The simple and innocent kiss shared between the two ignited a fire inside of both of them in a way that they had never experienced before. It was as though their lips were perfectly made to kiss the other's.

Eventually Aaron pulled away, breaking the kiss and leaving JJ flushed and breathing erratically as he pressed a kiss against her cheek. He kept his face close to hers, smiling to himself as he stared at the beautiful woman in front of him, her eyes still closed as she attempted to recover from their kiss. His own eyes closed as he leaned forward, his forehead pressing against hers for a moment before he kissed her other cheek. "You have no idea how long I've thought of kissing you."

JJ quietly laughed and finally opened her eyes, staring intently at Aaron as he stared right back. "I promise, I've thought of kissing you longer." The two shared a quiet laugh before Aaron leaned forward, pressing another passionate kiss to JJ's lips, absolutely addicted to her, just as she was to him.
