Chapter Text
Ymir awoke gradually, unsure of when she'd even fallen asleep. She felt... off. For reasons that only became clear when she tried to roll over and sleep through it. Her arms had gotten in the way. Their wrists were stuck — attached to the collar someone had buckled back onto her neck.
She sprang up with a burning sense of deja vu, looking for Yelena and finding relief.
Historia lounged about on the bed, belly down and feet up, lazily kicking at the air and using her forearms as a pillow. She also happened to be naked, unlike Ymir. Although the markedly less relieved brunette wasn't too far off either.
Ymir's fists were kept closed and useless by the bondage mittens she was so fond of locking onto her girlfriend. Save for that, she wore nothing but panties — a pair too pretty and pink to be her own... Historia was really gonna get it this time. Although Ymir was in no state to give it; not with her cock amounting to nothing more than a pathetic, caged bulge that thankfully knew better than to react to... this. Historia's eyes may have been asking for a fuck, but it wasn't the kind Ymir was after...
"Is something wrong, babe?" Historia asked like she didn't know or care to learn.
Ymir sighed, doing nothing to hide her frustration. "You know how in the movies the good guys get locked up, but then escape in like five minutes because they grab the guard through the bars?"
"And how they'd only make things worse if the guard had a buddy or kept the keys away? Yes. What about it?"
"Oh nothing, I'll just remember the guard's face for when I get out." Ymir wiggled her elbows. Menacingly.
"Well don't tell him or he might not let you out at all, babe."
"'Her', actually. As in 'I'm gonna punish her like you wouldn't believe after she lets me go'."
"Which she's going to do because...?" Historia wondered, observing her fingernails.
"Got it on good authority she likes dick too much to wait long. And the longer she does, the worse she'll be punished."
"Maybe she won't mind a little punishment. Or maybe..." Historia reached into the valley between her petite breasts and unsheathed an old friend. It was fat, curved, pink, and armed with all the settings a lonely girl could ever need. "Maybe she'll just use her nightstick..." It came to life at the press of a button, making the smiling blonde's hand vibrate alongside it.
Ymir clenched up the moment it began to buzz. Her tight, virgin ass was in no way prepared to get fucked by that stud of a vibrator. It'd take like an hour to fit! And for some stupid, crazy reason, the thought still slipped into her head — just what would it be like to have Historia break her in with that fat, wiggling tip...?
A giggle stopped that cursed train of thought. "That's still a bit big for you, babe." Historia shut her vibrator off and pushed herself up to show what else her tits had been hiding. The cellphone was harmless enough, but the lube? The egg vibrator...? Yeah, that was going up someone's ass. "We have to start out small."
"Do we?" Ymir gave the pink lump a concerned look, warily closing her legs. Historia looked surprised. And excited. "-Have to start at all!?" the brunette scrambled to clarify.
"Do you have to cum at all?" Historia wondered, squeezing a trail of lube out onto her finger. Like toothpaste on a toothbrush.
Ymir just frowned at the playful non-question and crossed her ankles to make things difficult.
"We could always try another blowjob if-"
"Or literally anything else."
"Right." Historia got to work wrangling Ymir's legs, a bit irked by their thrashing. A merciless smack calmed them down, and left a stinging, red handprint on the side of Ymir's ass. "Spread your legs," Historia demanded.
Ymir did nothing but leak into her cage... Her mind raced to find out why. Why now of all times? It couldn't possibly be that she... liked Historia getting bossy. And impatient. The bitchy little blonde spanked her again. "I hope you know how fucked your ass will be the day I-" And again. And again, as if to slap the disobedience out of her.
"Sure. You can have mine right after you take Yelena's. That is what you want, isn't it? To get back at us." Rather than raise her hand again, Historia reached for Ymir's panty-clad sack and caught it before the startled brunette could react.
"Alright! Fine!" Ymir spread her legs before the threat became something more. She wasn't released, only regarded with the slightest hint of a smirk.
"Was that an 'Alright, fine, I keep thinking about fucking you both' or...?" Historia tightened her grip ever so slightly.
Ymir briefly considered whether or not the truth would bite her in the ass and went with it anyway. "Yeah..."
"I didn't catch that. Put your legs on my shoulders like you're about to get fucked, for 'yes'." Historia caught Ymir's defiance early and nipped it in the bud. "Give Yelena a call for 'no'."
Ymir reluctantly gave her a 'yes', knowing how slippery a slope she was treading. It didn't take much to imagine a cock strapped to Historia's hips and stuck up the brunette's ass.
"You know, her ex used to give it to her all the time. But never in the back. You'd be her first," Historia mused as she rubbed the cool, slick gel into Ymir's asshole and wriggled a finger past the tightly clenched muscle. "It's too bad she'll never let you." Ymir tried to keep quiet, but Historia wouldn't let her. Her finger drove in and out, slowly, gently, but without compromise. She even began moving her hips in tandem with each thrust, all to the tune of soft, hard-won moans. "Never ever. Unless you make another bet and see where it gets you. You'd have the upper hand; it's not like she can jerk you off this time."
"Why don't you... give it a shot?" Ymir said between stifled moans.
"Already got what I want. What's your excuse? Afraid she'll milk you... just... like... this...?"
Ymir gasped, then gritted her teeth. Historia didn't know what she was doing — not the way a certain cougar did — but she really didn't need to. It was only one finger, patient and lubed to the point where little could go wrong. Its deep, drawn-out thrusts couldn't help but graze Ymir's prostate, making her toes curl. And drawing Historia's attention.
"Afraid you'll get hooked? That's spilled milk, babe. Why not spill some more? That's what you want, isn't it?"
"..."
"So just give up and let her fuck you already," Historia said upon brushing up against the prostate and digging her fingertip into its center. There was no way she could miss the growing stain on Ymir's new panties. Or the whimpering that announced it. "You should have told me you like it this bad, slave."
"I don't," Ymir said through gritted teeth, refusing to meet Historia's eyes and risk exposing the lie.
"Right. Okay." Historia's finger drew back, slipping all the way out of Ymir's loosened, winking hole, and returning with the egg vibrator. There was so much lube it could have slipped in without a fuss. She wouldn't let it, so Historia turned it on. The lowest setting was enough. It made Ymir squirm like this was her very first time. And Historia kept moving her hips, letting the disheveled brunette know just what awaited her. Making sure they both had it in mind, as much as Ymir tried to keep it out. Her attempts were not as fervent now...
"Fine, I get it... Moral of the story: being pushy's bad... I've been bad," Ymir flushed and regretted saying, "a-and I won't do it again."
"Cute but wrong. The moral of the story is I'm gonna push right back." Historia gave her a smug look. "And you'll like it."
Ymir caught the glint in Historia's eyes... and relaxed. It was only for an instant and she hadn't meant to do it, but the egg slipped into her all the same — soothing the slight discomfort with gentle vibrations. Helping her forget it even existed. Clamping down on the egg was just too intense, so Historia had no trouble getting it inside, cooing at how smoothly it entered her big, tough girlfriend's ass.
"That's it. Just think of it as a biiig, buzzing suppository. It'll make you feel so much better."
Ymir could only moan as control slipped further away. She couldn't even wipe away the thin trickle of drool at her lips. The gentle buzzing softened her up just right. And it just kept going. Deeper. Closer to that big, tender bump. Nudged along by two slippery digits.
"Such a pretty slave. There we go. No need to keep pretending there's none of this in your search history."
Crap... "Doesn't mean I... wanna be the sub..."
"Mhm."
"Just 'cause- hah!" Ymir moaned as the vibrator bumped into her prostate. She tried to speak again, only to experience the vibrator's highest setting. Meaningless words left her mouth, distorted by a shudder intense enough to be visible. It was too much, being dominated by the subbiest sub to ever sub with the single press of a button...
Historia dragged a hand along Ymir's thigh, forcing her to acknowledge the goosebumps there. "Feeling good, slave?"
Ymir nodded without hesitation. Her dull gaze lingered on the ceiling. She could do nothing but breathe, clench her fists even harder, and make noise for her new domme.
"Woah... You're really sensitive down there..."
"Yeah..."
"Think you could, uh... are you gonna...?"
Ymir didn't dare say how close she'd gotten. She needed it so, so badly. There was no way she could risk being denied this orgasm. But there was no way she would be. That much became clear the moment the slack-jawed surprise on Historia's face gave way to an excited grin.
"Yes. Yes, you are." Historia pumped her fingers hard, pushing the egg just a bit further so she could get at Ymir's prostate herself. The two-pronged assault was downright mind-melting. "Don't fight it. Cum for me."
Ymir wouldn't have dreamed of fighting it. She closed her eyes and surrendered to the first fantasy that came to mind. Her imagination was quick to conjure up a thoroughly pissed off, leather-clad Historia, complete with high-heeled boots, a funny hat and a riding crop that never stayed idle for long.
"You're so fucking close, babe. Such a good girl. Just a little closer!"
"Ffffuck..." Ymir gasped, biting her lip. The Historia in her head got her on all fours, correcting posture with overzealous application of the crop. Sticking her heel right up Ymir's ass while she got the strap-on ready. Lubing it up for her well-trained hole... And shoving it in.
"Yeah! Yeah! Yeahyeahyeahyeahyeah!" Historia cooed, beside herself with glee, right as the cum leaked from Ymir's cage in tiny spurts that must have looked pathetic but felt so damn good!
The shame faded away. The preference for fucking and not getting fucked back was eclipsed. None of it mattered when she felt so wonderful...
...
Having given Ymir ample time to savor her first anal orgasm, Historia shook off the one leg that hadn't fallen from her shoulders mid-orgasm, and crept along the panting brunette's side on hands and knees. She took her vibrator along and giggled at the dazed confusion on her lover's face when she moved to mount it. Ymir was no stranger to eating her out, but doing it with the hole she'd been presented was definitely a first. "Kiss it. Don't worry, I got nice and cle-"
Ymir quietly dragged her tongue along her girlfriend's cute, pink pucker. Not even to mess with her or to be in control again. She hadn't given it any thought at all... Just what the hell had gotten into her?
Historia arched her back and looked down at Ymir over her shoulder, enjoying herself too much to be smug. "You sure mellowed out."
That snapped Ymir out of it, and now she was definitely doing it to be in control again. Although Historia didn't seem to care, busy as she was, burying the vibrator in her pussy. The drenched lips stretched around its head with hardly any preparation at all. The little upstart would be lucky to last a minute. It was about time to remind her how things worked in this household.
"Get to work, slave."
Ymir was well on her way to a post-orgasm nap when a flash of light grabbed her attention. It wasn't the first, nor the last. As such, she gave some thought to murdering her girlfriend real quick.
Historia had apparently recovered enough to crawl over to her phone. Clearly, she'd been tonguefucked too mercifully. She wouldn't get off so easily next time. "This is a good look for you, babe."
Ymir apparently looked funny, scowling in defiance. "Knock it off."
"You'll have to make me." Historia drowsily wiggled her elbows to rub salt in the wound.
"When'd you get to be such a bad girl? Thought all those spankings fixed you right up."
"Oh I'm the worst girl in the world, it's the spankings that tipped me over the edge."
"Not gonna stay in this world for long if you keep taking pics."
Historia reached over and shut her up with the press of a button, save for the soft, pathetic noises Ymir was too weak to stifle. "Roll over. Yelena wants to see."
Left with no choice, Ymir obeyed, staying put with her face down and ass up until the vibrations stopped.
The little blonde then rolled Ymir onto her side and detached the mittens from the collar, but was content to leave them on. It didn't matter; Ymir was too worn out to resist her and keep from getting spooned.
They laid there together, in silence, ignoring the frantic buzzing of Historia's phone. It seemed Yelena liked what she saw...
"You gonna get this thing off while we're still young?" Ymir grumbled, not entirely pleased by their new dynamic, much less the cage enabling it. "My birthday's coming up real soon, you know. I'm aging right now."
"Gracefully," Historia noted, taking great joy in playing the big spoon.
"Seriously, I get to pick a present too."
"I'm already working on it. But you can pick out a different one if you insist. I'm sure it won't be a massive downgrade."
Ymir just sighed in resignation. She really oughta kill her one of these days. Or marry her. One of those.
"It'll probably come a bit late though."
"...It's not an eight-inch hunk'a rubber, is it?"
"Not even close." Historia nuzzled into her back. "But Yelena's got you covered."
