Olivia stood off to the side, eyes intently focused on Alex who was smiling wide, pointing to the life-size train that kids could ride. Noah's chubby cheeks were squished up to his eyes from the width of his smile. He was giggling and clapping as they waited patiently in line so that Noah could ride the train.

She had to admit, she never imagined that Alex would be one to like kids. The blonde seemed to lack that empathy, at least when she was working at SVU. Or maybe she purposely didn't relate because Olivia knew all too well how much that ended up biting her in the ass. Although she couldn't complain. Despite her connection to kids resulting in her temporarily having a son, Calvin, before having him ripped away, she now had Noah. The adoption was finalized which meant no one could take him away from her without one hell of a fight.

"Liv, you coming?" Alex called as she waved at the brunette. The former ADA was standing in front of the now stopped train, door wide open for her to enter with Noah.

"Yeah," she replied as she quickly walked over to the train and slid into the booth seat next to Alex who currently had Noah propped up on her lap. "Do you want me to take him? I know how heavy he is when he makes you carry him."

"No it's alright. I miss spending time with such happy children. There always seems to be horror around the kids I most spend time with."

Olivia smiled sadly as she looked over the blonde. "Well, he seems to be taken with you…and he definitely has you wrapped around his little finger!" Olivia commented as she watched her son tap Alex's leg, indicating that he wanted to stand. Alex adjusted appropriately immediately.

Alex grinned as she held onto his waist so he could peek out the window. "Yeah, well, he's not the only Benson that has me wrapped around their finger," she teased as she smiled back at the brunette. "How you managed to convince me to go to a museum about trains, I'll never know."

"I think knowing that Noah was coming with sold that one for you. I had nothing to do with it."

"True, this little sweetheart knows how to steal hearts already, isn't that right Noah?" Alex cooed to the little boy as she tickled his sides. He collapsed back down onto her lap in a fit of giggles, reaching for his mom in an attempt to escape the tickling.

"I'm not helping you my sweet boy," Olivia teased as she admired how happy her son was in Alex's arms. There was something about the two of them together that made her heart swell. Alex's blue eyes sparkled every time she looked at Noah and there was something so entrancing about the way Alex looked back at her.

She couldn't help herself. In that moment, she was completely lost and didn't bother thinking as she leaned forward and pressed a kiss to Alex's smiling mouth. She just wanted to taste the blonde and feel the happiness radiating off of her.

She pulled away quickly, face flaming as she realized that she had just kissed the blonde in public. She doubted that anyone saw, especially since they were in a moving train for children. "Sorry," she mumbled as she quickly turned away to look out the train.

For her part, Alex didn't mind. Kissing the lieutenant in public almost felt natural. It wasn't deep, merely a peck on her lips, but it felt so normal. "It's fine," Alex assured her as she smiled at the brunette, even though she was turned away and still looking out the train. She turned her attention back to Noah. "Look, Noah! There's the water fountain that we saw this morning!"

"Wada!" He cried out, clapping his hands before attempting to crawl toward the window for a better view.

Alex pursed her lips as she walked into Olivia's bedroom and studied the brunette. She had just set Noah down for his nap, allowing Olivia to go change into something more comfortable. She was currently spread out on the bed in a pair of sweats and a loose fitting shirt, one hand holding up a book which was blocking the view of her black framed glasses.

"Are you going to tell me what's been on your mind ever since the train ride?" Alex finally asked, watching as she slowly set down her book. She had to admit, Olivia looked surprisingly great in glasses.

She merely shrugged in response, setting her book to the side and pulling off her glasses. "Nothing, just tired."

"You're a horrible liar…"

"Yeah, yeah. It's not important," Olivia replied as she stretched out momentarily before patting the open spot on the bed next to her. "How about you come over here and entertain me?" She smiled deviously as she tossed the blonde a flirtatious wink.

Alex shut and locked the door behind her. "I guess it's a good thing we tired Noah out earlier." She crawled across the bed and settled above the lieutenant, slowly leaning forward and connecting their lips. She was reminded briefly of their kiss earlier which she knew was the reason Olivia was acting odd.

Hands quickly slid up Alex's back, pushing her shirt up until she was forced to take it off. The article was discarded to the side before Olivia took advantage of bare skin and trailed her fingers across Alex's side and over her toned stomach. "How is it possible that your body is this perfect, even at your age?"

Alex pulled back with a chuckle. "Who are you calling old, lieutenant?" She playfully slapped Olivia's shoulder before grabbing at her shirt to remove it as well. "Besides, you're not too shabby yourself and you've got a few years on me."

"I'm…softer now," Olivia admitted. She had no qualms with her body and honestly enjoyed the new curves she could flaunt. Men didn't seem to mind either. "You on the other hand are just as gorgeous as the day I met you. So soft," she snapped the back of Alex's bra open and allowed it to fall off of her breasts, "and lightly toned creamy flesh."

"You never saw me naked back then, how would you know?" Alex teased back as she returned the favor and removed Olivia's bra as well.

"A girl can imagine…"

"Mhm, Ms. I don't check girls out!" Alex took a moment to admire the woman before her as well. She had seen Olivia as close to naked with clothes still on in the past when she had gone after her to discuss an unauthorized search. She had barged in on the former detective sitting on a bed in the crib, shirtless with her slacks around her ankles. Apparently she was the only one that didn't get the memo that a victim had thrown up on Olivia and was upstairs changing. Or she just didn't bother listening.

Olivia was toned beyond belief back then. Strong muscles rippling beneath thin sheets of tanned skin. She had to admit, she envied the detective's body back then, despite being just as thin. There was something about the way Olivia could hold a muscle that wasn't common in women.

Even now, despite being on the softer side, Olivia's muscles were still prominent. She could feel the power hidden in Olivia's legs when thighs clenched around her head during their sexual encounters. She could see the lieutenant's biceps flex and strain as she fisted sheets beneath her fingers or held herself over Alex's body.

Olivia Benson was absolutely breathtaking; there was no arguing that. "Why are you staring?" Olivia's question broke Alex out of her spell.

"You're breathtaking, you know that?"

"You're already allowed in my pants, you don't need to keep charming me Cabot," Olivia playfully teased.

"No charming… Just honesty."

Olivia hummed in response before pulling Alex back into a kiss and divesting her of the rest of her clothes.

When they were down, Alex hovered above Olivia's body, both elbows supporting her above the lieutenant as they caught their breath. "Come here," Olivia murmured, not waiting for a response as she pulled Alex down on top of her so that their bodies were pressed flush against one another.

She sighed contently at the feeling of Alex's weight on top of her. Despite both of them being sweaty and naked, she enjoyed the closeness that she felt when holding someone. Alex relaxed against her body, instantly and burrowed her face against the brunette's neck as fingers slowly drew meaningless shapes across her back.

"Can we just stay like this and take a quick nap?" Alex questioned with a whisper. She imagined that Noah would be up soon but her entire body felt so completely spent and relaxed. The only response she received was a soft grunt and the feeling of a thin bed sheet being pulled over her exposed back. It took mere minutes for both women to fall fast asleep.
