A/N: Here comes the rating change! And there might be more sex in the next one, not sure yet. Just fyi lol. Slightly terrified to post this, it's been a long ass time since I wrote any smut and pretty much never since I posted it without a beta lol but here goes nothing!

"You seriously didn't hear a little girl crying?" Buck asked.

"I already told you, no."

"It was so loud though, that guy beside me heard it too."

"Or he just went along with it so you wouldn't look crazy."

"Hey, I know what I heard."

Abby put her hands up in defeat, "okay, okay, you heard it."

"Ghosts are real."

"I believe you."

"No you don't."

"No, I don't."

"That's okay," he said, kissing her lightly, "I love you anyways."

"Well that's a relief. I'm going to get ready for bed."

Abby waited until she was sure he wasn't looking before she sneaked a shopping bag out of her suitcase and brought it to the bathroom with her. After two previously thwarted attempts to start something with Buck, she was stepping up her game. She knew he was still worried about her and scared of hurting her, but she was dying to feel him again. If he needed her to spell it out for him that she definitely wanted this and could handle it, then that's what she would do.

When she came back out, Buck had already stripped down to his boxers and was sitting on the bed, scrolling through something on his phone. Perfect.

"What do you think of my new shirt?" she asked to get his attention. It was one of those classic cliché t-shirts that said 'Kiss Me, I'm Irish', just big enough to reach the top of her thighs and just sheer white enough for a faint hint of colour to show through.

He looked up and smiled. "I like anything that gives me an excuse to kiss you."

As she came closer, she watched his eyes darken as he noticed there was something bold underneath it. She climbed onto the bed and moved to straddle his lap, reaching over to place her glasses on the nightstand.

"How much do you like it?"

His hands immediately moved to play with the hem of it despite the hesitation she could still see on his face.

"Umm…"

"Would you like it better if I took it off?"

"Abby –"

She silenced him with a hot, passionate kiss.

"Please," she breathed against his lips.

That was all it took to snap his remaining self-control. He grabbed her hips and kissed her hard. He had her breathless in only moments and she couldn't stop herself from grinding against him. She had almost completely forgotten about the second part of her surprise until he moved to nip at the sensitive spot below her ear and murmured something.

"I think I would like the shirt off better."

OH, right, that. She leaned back and whipped the shirt off, revealing the lacy, burgundy lingerie set she had picked out this afternoon.

"Damn, Abby."

"You like your surprise?"

"Oh yeah… but I'm going to like unwrapping it more."

Suddenly she was on her back, and his lips were on her neck again while his hands roamed over the soft, silky lace covering her. When he reached the edge of her bra, he popped the clasp and lavished attention on her one breast with his mouth, taking the other in his hand and gently tweaking the nipple with his fingers. She moaned and clutched at the sheets, her back arching off the bed. It may only have been three weeks since they were skin to skin, but now that seemed like an eternity. They were just getting started and she was already on fire.

Buck continued working his way down her body and slowly dragged her panties down her legs before returning to her thighs, pressing rough kisses along the soft skin on the inside. She knew where his mouth was headed next but God help her, she was already close, and she had to have him now. Just as he reached her entrance, she tugged at his hair and pulled him back to her lips.

"Please," she whispered in between kisses, "I need you."

A minute later he was sliding into her, groaning her name, and she gasped. He was a tight fit for her, and the first pass had her seeing stars every time.

"You okay?" He asked, kissing her softly.

Words were failing her so she simply nodded, and he started up a slow rhythm of deep thrusts that had her whole body trembling in no time. She really hoped he was as desperate as she was, because she wouldn't last long like this. A whimper escaped her lips every time he slid home, and all she could manage was to clutch at his shoulders and hold on for the ride. He gripped her hips and picked up the pace, and she could almost taste her release on the tip of her tongue.

"Buck," she gasped, "I can't – " she couldn't get anything else out.

"Let go," he assured her.

He shifted and changed the angle just slightly, and she couldn't hold back any longer. With a keening cry, she shattered around him. He continued thrusting through her climax, prolonging the waves of pleasure until he followed her over the edge. He held her tightly and rolled onto his back, bringing her to rest on top of him while they caught their breath. She closed her eyes and listened to his heartbeat slow while he gently ran his fingers through her hair.

After a minute, he spoke. "I was going to wait until tomorrow to give you your surprise, but I kind of feel like I should give it to you now."

She laughed quietly. "You don't have to, I can wait."

"I know, but I think I want you to have it now."

"But that means I have to move."

"It means I have to move," he corrected, "I'll be right back."

He carefully shifted her to the side and got up, digging a small box out of his suitcase. For a second her heart stopped – it wasn't… that, right? She definitely wasn't collected enough to process that right now. But as he came closer, she realized the box was the wrong shape for that and truth be told, she was a little relieved. It wasn't that she didn't want that, but she really needed to get herself together first. She sat up and he got back into bed beside her, shyly handing her the box. God he was cute.

She opened the lid to reveal a sterling silver chain with an infinity pendant, featuring a round diamond at the bottom. Holy shit.

"Oh my God, Buck… you didn't have to do this."

"I want you to know that I'm serious when I say I'll be waiting whenever you're ready. Whether you decide to come home in a few days or a few months, I'll be there. I'm in this, no matter what."

Her eyes filled with tears. "How are you so amazing?"

"You're amazing, I'm just trying to keep up."

Wrapping her arms around his neck, she pulled him into a tight hug. "Thank you, I love it."

After a minute she reluctantly let go and turned around. "Can you put it on me?" she asked, looking over her shoulder.

He smiled and happily obliged, turning her back to face him when he done.

"How does it look?"

"Beautiful," he answered, kissing her softly.

She reached over and switched off the lamp on the night table, and together they curled up under the blankets. Feeling warm and secure in his arms, she fell asleep thinking that she was surely the luckiest woman in the world.

A/N: So, question for future reference – how do y'all feel about like… more explicit smut? Like I consider this fairly "literary" smut lol, are you guys more comfortable with this kind of thing or are you open to something a little less… soft? Like, less flowery, more blunt, I guess – not really sure the best way to describe it. I'm not saying you're going to GET that lol, I'm definitely more comfortable writing it this way, but I prefer reading the other, so I guess I'm just curious that if I were to try something more like that, would there be an audience for that beyond myself lol.
