Summary
After deciding to sue the department, Buck finds out he has a daughter that he didn't know about. Getting her in his care, he needs to learn how to be the dad she deserves while fighting to get his job back, mending relationships, and navigating the realization that his best friend might mean more to him than what he's been thinking this whole time.
Basically it's girl dad Buck with slowburn Buddie
(Ps I mainly chose lawsuit era so that the kids could be closer in age 🤷🏻 if you don't like lawsuit era fics I swear that it's not super relevant past a certain point in the fic. It's very buddie heavy and cute and silly for the most part)

Summary
Of course, the way Buck proposed to Tommy wasn’t perfect. There was no ring, no one knee, nothing ideal like that. But he did it for all the right reasons, yeah? The timing was a bit off but it would’ve happened anyway. It didn’t really have anything to do with Eddie, or his so called “feelings” for him. No. Absolutely not.
But then a few weeks go by, and he’s still not over-the-moon excited in the same way Maddie was the weeks leading up to her wedding.
The whole thing is a bit rushed, isn’t it?
But Buck is set with going through with it. Surely when his, say, bachelor party comes around he’ll be excited. (And he will be, just maybe not for the right reason…)

Summary
Eddie has tried for so long to not interfere, to not tell Buck how he feels. However when Buck gets jealous of Eddie with another guy Eddie decides he doesn’t need to hold back anymore…….which leads to Buck dumping Tommy in a very interesting way.
Btw….Tommy isn’t really even present other than to be dumped quickly. (And also cheated on)

Summary

Summary
The 118 goes for a night out:
Buck and Tommy are a couple, much to everyone's dismay.
Eddie is a possessive freak, to everyone's (but mostly Ravi's) joyAnd the 118 is so *so* so very done with all three of them
Cue platonic kisses (that are not that platonic after all) and a break up that was a long time coming.
Or: buckfidelity, but make it silly

Summary
“Does this change a thing between us?” Buck asks, his voice low, his hands still framing Eddie’s face. He can feel the unsteady breaths leaving Eddie’s lips, warm against his own.
Eddie looks wrecked. His cheeks are flushed, lips red and kiss-swollen, his glassy eyes locked on Buck’s mouth like it’s the only thing he can see. He looks as hungry as Buck feels. Buck feels Eddie’s fingers trace along his arms, squeezing just enough to leave his skin tingling.
“I don’t know.”
It’s not a yes—Buck’s not even sure he wants to hear a yes. But it’s so much better than the rejection Eddie threw at him before.
“Alright,” Buck exhales, nodding like it’s nothing, even though it feels massive. Then he surges forward, catching Eddie’s mouth in his again. The soft, desperate sound Eddie lets out—like relief and need tangled together—hits Buck like a punch to the chest.
or; Eddie’s shame torments him. Buck would rather have a piece of Eddie than nothing at all. Miscommunication is their biggest enemy. Infidelity turns into their savior… or ends up being the thing that destroys them?

“I wish you were always touching me,” Buck confesses quietly. “Why aren’t you always touching me?”
Eddie’s hand stills against his face.

Summary
For the Weewoo Kink Meme prompt, "Eddie comes on Buck's face as a treatment for his boils."
Exactly what it says on the tin.

Summary
Eddie's hands are gripping the elastic waist of Buck’s shorts now, knuckles white, and she can see where this is going, where they’re going to end up. Buck might be an unpredictable person to anyone else, but not to Eddie, never to Eddie. Eddie can see the end in every one of Buck’s beginnings.
And what’s starting now is going to end with them in bed.
The thought doesn’t scare Eddie as much as she thinks it should.
or, Eddie treats Buck the way she deserves to be treated.

Summary
Buck retrieved the ointment from the medical kit in silence. He shuffled closer, the sink no longer a roadblock between them, and settled right next to Eddie. As he started to apply it to the gash, Eddie cried out in pain, his body doubling over in retaliation and his head falling to rest on Buck’s shoulder for support.
Time froze.
Buck’s entire body stilled as the warmth of Eddie’s head against his shoulder began to bleed through his shirt and spread everywhere in his body like wildfire. An innocent touch, a response to pain from an injury, but a connection that ignited something inside of Buck.
Or; Buck tends to Eddie’s wounds in a not so platonic way.
Inspired by the wound cleaning scene in season three of ‘The Summer I Turned Pretty’

Summary
“I can’t, Buck!” Eddie shoots straight up now, nearly leaping off the couch and standing in front of Buck. “My… my parents, my God… they’ll never forgive me. I can’t… You can’t fix that in me, Buck. I wish, I wish my brain would let me choose you. But– but every time I imagine a future with you, a man, I feel the flames. The burns on my skin, the boils, my eternal torture,” Buck can see the tears well up in Eddie’s eyes.
“I’ll wait, then. For you,” Buck says.

Summary
He feels bad, of course he does, for going behind Tommy’s back like this but Eddie just gets Buck.
He understands him. What he likes and what makes him tick. Tommy is the safe option in his mind. But Buck would never feel safe and loved with Tommy the way he does with Eddie.
Although that is not what this thing between them is. It was just sex.
Maybe Buck did pretend in the moment it was something else, but he would never admit that to Eddie - so it remained just sex.
With his best friend.
Behind his boyfriend's back.or
another Buckfidelity fic where Buck and Eddie pass some time in the stockroom during a slow shift.

Summary
Just as Eddie starts to melt back into it, the phone buzzes again. Just as loud. Just as fucking insistent.
Eddie rips his mouth away with a frustrated sound, glaring down at where the phone is tucked away. “Seriously?”
Buck cringes as the buzzing continues. “Sorry. I’ll turn it off.”
He reaches into his pocket, but by the time it’s out, the call has timed out. Buck’s finger goes to hover over the lock button to shut the device off, but then the screen lights up again. Same buzzing. Same ringtone. This time, Tommy’s face and name flash brightly on the screen.
Eddie’s jaw clenches, hand still tightly fisted in Buck’s hair. “Answer it.” He says before he can stop himself.
Buck's head snaps up to look at him, eyes frantic and expression puzzled. “W-what? Now?”
“Buck,” Eddie says, voice firm and insistent, leaning in to ghost a kiss along Buck’s cheek. “Answer the phone.”

Summary
“I just feel…” Eddie starts, and then he’s shaking his head and blowing out a stiff breath, rubbing at his brow. “I don’t know, man. I need to get out of my head. It’s not a good place to be right now.”
Buck hums. Lightheartedly, he says, “I could always spank you again.”
Eddie chokes on his water where he was mid-sip, snorting and coughing around his own laughter. “Yeah, absolutely,” he says sarcastically, shoving at Buck playfully. “It worked so well last time.”
Their eyes meet, and a wave of energy shocks its way through Buck’s body. Not like a lightning strike; more like an electric fence, pulsing through his fingertips and dissipating in his chest, fizzling out into his ribcage.
“Well, it kinda did,” Buck croaks, throat aching and dry again already.

Summary
Buck and Ravi have been in an intense friends with benefits/situationship for...forever. It's kind of a disaster. Together they're codependent, dysfunctional, cruel, toxic, possessive, and Buck's realizing it's everything he's ever wanted.
5 times Buck cheats with Ravi, +1 time it's not cheating-----
“IkindofsleptwithRavithenightoftheBeenado.”
Eddie chokes on his beer, coughing and sputtering for several seconds while Buck waits patiently for him to recover. “Um-what?! Buck, what do you mean you kind of slept with Ravi?”
“Sorry, you're right. Saying ‘kind of’ is reductive and not fair to Ravi.”
“Yeah that’s definitely not the part I'm stuck on,” Eddie says slowly. "Well actually, we’re gonna circle back to that. Buck, the beenado was like two months ago-“
“Six and a half weeks, but hey! Who’s counting?"
“You, apparently. Okay so you and Ravi hook up six and a half weeks ago, and then…what?”
