Chapter Text
Dragging him to your shared bedroom, he seemed to know you were unhappy with them waking you up for seemingly nothing. Killer tried to think how Kid would act, but he couldn’t say he knew what the two of you were like behind closed doors, except… loud. When the two of you reached the room, you threw yourself on the bed and gestured for him to come too, but Killer froze when he saw your shirt lift enough to show the crease of your butt. You shot him a confused look, a soft hurtness mixed in your expression.
“Really, Kid? You’re not gonna sleep with me?” the hurt in your voice stung his heart, and he hurried to the bed on Kid’s side, avoiding touching you.
“Babe? Did I do something? Did I embarrass you?” Killer felt your hand stroke what you knew as your boyfriend's back, before your lips were at his ear, “let me make it up to you then~”.
Killer reddened instantly, and couldn’t help but feel his blood travel down south when your mouth breathed softly into his neck before warm lips kissed his skin, hand reaching for his front. ‘Okey Killer, think fast - Kid told to not let y/n get suspicious, right? Will she get suspicious if I don’t say anything, if I don’t get horny, or if I don’t let her continue?’ his mind was racing, not wanting to abuse your vulnerability either by making love to you, knowing you thought it was Kid, while also not going against his friend’s words.
“Actually, let me make it up to you,” he muttered, before turning, flipping you onto your back and pinning you down in mere seconds, hands above your head. Pink cheeks and a lustful gaze met his eyes, and you pushed your hips up against his growing erection.
“Well hello, what has gotten into you?~” you grinned at him, groaning at the contact and Killer had to bite his inner cheek, too used to holding back his own voice and sounds. He wondered what the best move would be next, but you were one step ahead of him, “I think you could put that mouth of yours to use, captain~”.
Why did he react so well to that? This is what Kid got to see and experience every day? Almost exhaling a purr before moving down your body, he placed himself between your soft thighs, seeing your wetness through your panties.
“Fuck,” he groaned just before pestering kisses on your inner thighs, your moans and giggles gaining a special spot in his brain. Your hands soon grabbed a fistful of his hair, trying to direct him where you needed him, and he gave in easily, locking eyes with you.
His hands hooked around the bands of your panties, and slowly dragged them down your legs, chuckling when you lifted your hips to aid. He choked on his breath when he saw your glistening cunt, waiting for him to please you.
“Fuck, you’re so beautiful,” he muttered lowly before throwing your legs over his shoulders, his metal hand keeping a hard grip on your squishy flesh, while his other hand started massaging your folds with two of his fingers. He swore his soul left his body when you threw your head back and whined, although it wasn’t him you were moaning for, but his best friend. ‘Shit, should I even be doing this?’ but he couldn’t help his selfishness when you begged him for more.
His fingers started rubbing down to your entrance before sliding back up, not forgetting about your sensitive bundle of nerves, absolutely adoring feeling your legs shake around him each time his fingers would grace against it, the hands in his hair hardening their grasp. He suddenly turned his hand upside down and used his palm to rub against your folds and clit, before slowly entering one of his fingers into your soaking cunt, grinning at your satisfied smile as you moaned for Kid.
“You’re going so soft on me today,” you purred through your heavy breaths, and he tried not to show concern. ‘Oh no, am I doing it wrong? Will she figure me out?’ but before he could lose his cool, he put on a smirk, adding another finger, slowly stretching your tight hole.
“What, I can’t spoil my good girl?” he was glad he finally got use of what he has heard every night since you boarded the ship, but he wasn’t prepared for how you tightened around his fingers at the pet name. He started a slow rhythm, feeling how your ribbed walls sucked his fingers in and tightened whenever he did something right. His rhythm never faltered, and the whines and cries that escaped your throat when his warm tongue worshipped your folds and very sensitive clit made him even more eager to please you. You felt a knot in your stomach swelling up, and your hips started grinding against the captain’s face, and Killer almost didn’t want you to cum just so he could stay between your legs forever, but the part that wanted to see you fall apart by his touch won by a mile. As a result, he was knuckles deep in you, curling his fingers inside you while dragging zigzag patterns against your folds, and you were a moaning, panting mess, knowing you would come soon.
“Oh Kid! Yes! Just like that, fuck!” you cried out the name of the one you thought were your boyfriend, but Killer felt pride in his chest when you threw your head backwards, eyes shut close, holding your breath as your legs shook wildly around the red-haired head, hands almost ripping his hair out. Feeling the continuous clamping and convulsion of your walls, he knew you were riding your high, so he kept licking and fingering you until you begged him to stop, not wanting to be overstimulated so late at night.
He dragged himself to lay beside you, instantly pulling you into his arms, thinking that would be the usual routine between the two of you, and he seemed to be right. So he just stayed quiet, ignoring his raging hard on as much as possible, your mixed panting filling the silence.
“You weren’t kidding when you said you would make it up to me,” you giggled breathlessly, and put your head in the crook of his arm that you loved so much, and he calmed down, but he felt your arm travel downwards, “but you’re sure you don’t want me to return the favor?”.
Your words had him twitching in excitement, but he couldn’t do that to his best friend. So with much regret, he told you no and excused it with him being too tired. This made you laugh.
“You, Eustass Kid, too tired to get his dick sucked?” you raised your brow at him, and Killer didn’t know how to respond any other way than with a wish to do it later.
“Alrighty then, you know where to find me,” you kissed his cheek, and he felt blush creeping up his neck. ‘She has to fall asleep soon’ he wished to himself as you nestled against his chest again, his heat a big comfort to you.
“By the way,” you didn’t turn to look at him, but stayed still, grabbing his bicep, “what was it with you and Killer today?”.
His blood ran cold, glad you couldn’t see his face. He tried to keep his calm, this shouldn’t be as scary as other things he had done, “what do you mean?” he asked innocently, hoping it wasn’t something bad, and you chuckled nervously at his response.
“You’ve been really calm, almost too calm,” and this made you sit up and look down at him, and he just kept quiet, “and Killer has avoided me all day,” a small hint of sadness could be detected in your voice as you looked down at your hands, “or, at least more than usual…”
You took his silence as him listening intently, and continued.
“If there’s something you don’t want to tell me, that’s fine, but I want to know if I have done something,” your voice was low, like it was something you didn’t want to say out loud.
“I thought me and Killer were finally on a good track!” and he furrowed his captain’s non-existing eyebrows together, concern in his eyes. What were you talking about?
You started twiddling your thumbs nervously, “you-you haven’t told him, have you? I want to do it myself, but I want to make him comfortable around me before I do that…” his heart started racing. WHAT were you talking about? Before he could gather his composure, you looked at him, eyes glazed and it looked like you were ready to cry.
“I haven’t told him anything,” he said, hoping it sounded believable, and that his voice was firm. It felt weird now having someone see the facial expressions he was making, but he got to know you a lot better just in this moment. And the he realized again he was in his captain and best friend’s body, having what could potentially be a deep and important conversation that he shouldn’t know about. After eating you out. He ate his best friend’s girlfriend out while being in his best friend’s body, without the girlfriend knowing this very important detail. ‘Fuck, Shit, I’ve fucked up, Kid, y/n, I’m so sorry' he tried not to show the battle currently in his mind. And he was glad when you smiled in relief at his words, drying your eyes with your palm.
“Okay that’s good,” it seemed like you were about to lie down again, and he almost let out a sigh of relief before you placed a hand on his chest, “but you’re sure you’re totally okay with it? Because you threw quite the tantrum last week when I said that Killer's buffer than you,” you laughed and he went bright red, eyes widening.
“I-Yes, I’m sure,” he mustered out, trying to sound lightly offended, not sure how much longer he could react as Kid, especially without knowing the context. So he tried to ask a vague question.
“Why haven’t you talked to Killer yet?” he almost cringed at referring to himself, it felt incredibly weird, but he had to know what you wanted to talk about.
“Tsk, it’s not that easy to talk to him when I’m just your girlfriend who suddenly started living here,” you tried to joke, but he could sense the small exhaustion in your voice, “do you think he hates me?” your eyes found his, and he sat up, grabbing your hand and stroked over it with his thumb, as it was something a boyfriend would do.
“What makes you think that?” his question came out rougher than intended because of Kid’s harsh and husky voice, but you looked down at where your hands met, yet you stayed silent for a moment.
“He barely talks to me, and whenever I walk into the room, he walks out…” your voice was barely a whisper, but he heard it like it was shouted from the rooftops. His mouth started to dry. ‘She thinks I hate her? Is that why Kid always try to make the three of us spend time together?’ he started reflecting on his own behavior, without exposing himself to you.
‘Shit. How did it come to this?' he had never meant to make you feel excluded or isolated, he just didn’t want you nor Kid to see how you made his day just the tiniest bit better by allowing his ears to be blessed by your voice, how just a glance at your body sometimes had him rushing to either his room or bathroom. He didn’t want to ruin anything between him and his best friend just because of a stupid crush he couldn’t control. But fuck if this evening haven’t made things worse. How could he ever tell Kid he misused your trust and went down on you in his body? He knew how possessive Kid was over you, trying to kill anyone who looked your way.
“I can talk to him, if you want,” he offered in a soft voice, or at least as controlled as he could, seeing how upset you were, and you gave him a small smile before hugging him. With your face buried in his neck, he finally felt relaxed, not having you look at his face.
“I don’t know what’s gotten into you, but it wouldn’t hurt for you to be like this more often,” you sniffled and planted a soft kiss on his neck, making goosebumps rise on his skin, and he couldn’t help but let out a small groan, immediately embarrassed. He noticed you tensing up, and you raised yourself enough to see his red face again, a small smirk on your lips.
“The offer’s still up~” your flirty tone made him gulp as he again tried to come up with an excuse, irresistible eyes glancing at him.
