-Ayako's POV-
Tsubasa signs the check after it gets brought back and slips her card in her wallet before fixing her gaze on me and I slump down low in the booth seat next to Kurumi, trying to make myself disappear into the fabric of the chair. I could feel my cheeks were flaming red with embarrassment. Across the table from me Miku watches, eyes shining with excitement as she hears the story behind my doujinshi unfold. "Wait, so you two fu-." She starts saying, but Tsubasa quickly slaps her hand over the idol's mouth.
"Miku please, have some restraint. Ayako is already practically dying from embarrassment over there. The least you can do is let the poor girl recover a bit after hearing that story. Besides, you three belong to me, I don't want you shouting this story out for everyone in the restaurant to learn of Ayako's humiliating day with Kurumi do you?" The thought alone makes me slide further down my seat, hiding my face, but that also makes it so I don't notice the devilish look shared between the three girls.
I let out a tired sigh as we slip out of the booth and Tsubasa leaves a generous tip before grabbing my hand and pulls me from the restaurant, smiling at me and giving me a tight squeeze. I smile back at her and return the affectionate squeeze as we continue on our way, deciding to head home for the day rather than return to the expo hall. By this time of day most of the good places have closed and to get anything of theirs, they'd have to come in early the next day, which I fully intend to do.
When we reach the street we usually turn on however, Tsubasa continues to pull me along heading instead, towards the central plaza over by the expo center. "Um… Onee-sama, I thought we were going home? I'm honestly pretty exhausted. I wanna just take a bath and relax for the rest of the day." I look up at her curiously as she just smirks back over her shoulder and stops when we get to the very middle of the busy plaza and claps her hands loudly.
The space around them ripples for a moment and I look around confused, trying to figure out what just happened. My analysis is cut short as Kurumi and Miki rips my clothes off, leaving them undamaged thanks to Tsubasa's powers. I scream and move to cover myself up but Tsubasa grabs my wrists and holds them firmly. "Ayachi, there's no way I could let you go home without some fun first. Not after hearing that Kurumi got to have so much fun with you and I wasn't invited."
"Like you didn't know what we were doing Tsubasa. I know you started watching before we even finished in our first location. Probably pleasuring yourself at your desk rather than doing your work like you were supposed to." Kurumi says, the snark plain in her voice as she challenges her girlfriend.
"Keep up the attitude and you won't get to enjoy playing with Ayako this time. You'll just have to sit there and watch as Miku and I play with her." The gothic girl balks slightly at Tsubasa's threat before grumbling. "That's what I thought." Smirking at her girlfriend, Tsubasa gives a nod to Miku who smiles and returns the nod.
"You're all mine Ayachi. Those two get to enjoy you all the time and it makes me feel a little left out, so let's fix that a little bit right now." The idol says, stepping up in front of me. My face heats up as I see that she's already naked, her full breasts swaying in front of me teasingly, her nipples already hard, showing her excitement. She cups my face lightly and pulls me into a kiss, her soft lips locking with my own. Her hands leave my face and she rests them on my hips, rubbing and squeezing me gently as her tongue slides into my mouth, and I start to forget where we are, just enjoying my brief moment with Miku.
I give a startled yelp as the idol suddenly pushes me back. My feet catch on something and I stumble, falling, only to feel my back land against something warm and soft. I glance over my shoulder and see Kurumi standing there, smiling at me almost a little too sweetly for my liking. "We can't have you falling and hurting yourself, so let me guide you down gently." She says with a small giggle. Before I have the chance to ask her what she means I finally notice Tsubasa laying on the ground, staring up at me and waiting patiently, her cock standing hard and ready for her little sister to attend to it.
As she said, Kurumi lowers me down slowly, lining my ass up perfectly with her throbbing cock. I let out a small squeak as I feel Tsubasa's head press against my tight pucker and try to squirm away, but before I can voice my protests Kurumi pushes down on me hard, shoving my sister's thick cock right into my ass and making me scream loudly. I shudder for a moment, shocked by the sudden large insertion in my ass. While I was used to taking her cock, it still wasn't something easy, she was always so huge. "My my, if they didn't know you were here getting fucked before Ayako, they certainly do now, so be a good girl and pleasure us all." Kurumi says, her voice soft and seductive as she gives one more hard push, shoving me down the rest of Tsubasa's length and sheathing it deep inside my tight ass. I let out a loud groan as Tsubasa's cock stretches out my belly with ease thanks to her massive size.
"Don't forget about me Ayachi." Miku's singsong voice drags my gaze upward and what I see causes me to freeze, wide eyed. Hanging above my face is a thick, lifelike strap on, easily as big as Kurumi, maybe larger. As the shadow of the toy falls over my face Miku grins widely above it and grinds it against my face. "I get to have the least fun with you, but today Onee-sama said I could have as much fun with you as I wanted." With that Miku lays down fully, her toy only causes her a little bit of an issue as she gets down and pushes her face between mine and Tsubasa's legs, a lewd grin on her face.
Tsubasa let's out a small groan of appreciation as Miku shoves her nose into the woman's large sack and kisses them soundly. Only staying there for a few moments however, Miku starts lapping at the heavy nuts churning with thick cum before licking the base of Tsubasa's cock, already slick with Ayako's juices before continuing her long lick upwards, licking the underside of whatever part of Tsubasa's cock wasn't buried inside me before continuing up, licking along my taint and up my soaked lips before she flicks her tongue off my clit, causing me to let out a small cry from the sudden pleasure. "Mmm, you two are both delicious." She says, sitting up straight and licking my juices off her lips slowly.
My face flushes hard as she does this and I bite my lip to keep quiet, but that only lasts a moment before Miku wraps her lips around my clit and starts sucking. I scream loudly and throw my head back in pleasure, my back arching up as she continues to tease my sensitive bean, dragging her teeth over it gently. Tsubasa holds me down, my head resting on her chest as Miku eats me out diligently. She doesn't move her cock around inside my ass, letting the idol enjoy her time pleasuring me to her heart's content as I just get more and more aroused by Miku's expert teasing. She grinds her warm tongue over my clit, hard enough for me to feel the bumps on her tongue as she licks up it, flicking her tongue off of it. I scream again, my whole body shuddering in response as I cum hard, spraying my juices all over Miku''s face before she manages to start gulping it all down.
Sitting back, Miku licks any juices still on her lips away and smiles down at my trembling form, a look of hunger and desire in her eyes. "Ayako, you're so delicious, your nectar is almost addicting, I just want more. Unfortunately, I can't keep Onee-sama waiting too long now can I? If I do, who knows what kind of punishment she'll put me through." I stare up at her, slightly dazed still from my orgasm that was just beginning to ebb when Miku straightens up and lines up a very high quality strap-on with my slit. She takes a moment to grind it against me, getting it nice and wet with my juices while making me whine in pleasure at the same time. "This is a very special toy. Onee-sama had it developed using some realizer technology, I can feel everything through it as if I really had a dick. With this I'll finally get to become one with my adorable Ayachi, and show everyone in this park what a lewd little slut she is!"
These words snap me back to reality, remembering once again we're in the middle of the park. I try to sit up but Tsubasa's strong arms hold me down atop her, making it easy for Miku to spread my legs nice and wide and start pushing into my tight hole. Our gasps of pleasure mix together as Miku slowly pushes her toy inside me, stretching me out and stuffing me more than normal thanks to Tsubasa filling my ass up completely. Miku pants heavily as she reaches about the halfway point, her whole body trembling from the forgein sensation of my tight warm tunnel wrapping around her length. "It's hard isn't it, resisting the pleasure her delicious body has to offer." Kurumi's wicked voice whispers in the idol's ear, causing the struggling girl to shudder softly. "You were so confident you could handle this at first Miku, but now you're quivering like a virgin and only half way in, don't tell me you're going to tap out now." The taunting continues and Miku's trembling stops. She places her hands on my hips and grips me firmly and with a single thrust sheaths the rest of her member inside me, her head easily slamming into my cervix and making me cry out loudly.
With her cock now inside me Miku doesn't hold back. With her grip tightening further, Miku pulls back all the way to the head before hammering her cock back into my core, her head slamming against my cervix with enough force to pierce it with a single thrust, hilting her cock in my tight womb. "F-Fuck this feels so amazing! I can't believe I've been missing out on this feeling for so long!" Miku howls loudly as she sets up a fast pace, thrusting hard into me over and over again, making my body lurch with each desperate thrust as she ruts my tight hole.
Tsubasa sniggers above my head smirking as Miku loses herself to the overstimulation of her new, temporary appendage. Just from watching her go wild on me she knew she'd have to train the idol on how to use that properly. While it's true she was making me moan in pleasure, that's more thanks to the size than the technique she is using as she practically humps me, more concerned with feeling good herself than pleasuring me. With a small shift Tsubasa starts thrusting as well, not matching Miku's frantic thrusting but instead sets a steady pace to scroop my insides out with her cock.
I howl in pleasure as Tsubasa starts thrusting into me, distending my belly with every powerful thrust of her cock. I quickly turn into a drooling mess as the two of them hammer my insides, thrusting as deep as they can with every thrust of their cocks, thoroughly stuffing my insides while everyone around watches me get completely fucked. I let out a small whine as Tsubasa; cups my breasts gently and starts massaging my petite chest. "I don't care what you think Ayako, your chest is absolutely perfect. They fill my hands nicely and you have such cute nipples. They're adorable." She murmurs softly, a strange thing to say considering the setting, but with that she starts thrusting harder, slamming her hips against my ass firmly with each thrust, pulling even louder moans from me. "With that said you're also my lewd little sister, so I'll help you indulge your erotic kink of getting fucked while everyone is watching."
My eyes roll back into my head as my mouth hangs open, a constant string of moans rolling off my lolling tongue. The combined pleasure was so good I couldn't close my mouth even if I had half a mind to do so. I whine and moan loudly, rolling my hips with their thrusts as my body begs for more. "O-Onee-sama! Miku! Please fuck me harder! Let's show everyone how lewd we are and how much we love each other! I want everyone to know I belong to you!" I finally scream, unable to hold back any longer. This snaps Miku back slightly as she bends over and captures my lips in a heated kiss as she thrusts hard one more time, trembling as she cums herself, moaning into the kiss without restraint. Tsubasa moans at the sight, biting her own lip as she thrusts her cock deep inside my ass and unleashes a torrent of cum, the feeling of her filling me with her seed helps push me over the edge and makes me cum hard, my juices staining the ground under us in a large puddle, unlike the small orgasms I was having earlier, this one nearly knocks me out cold, the whole world going fuzzy as I lay back against Tsubasa panting hard.
"Looks like I won't get my turn tonight, shall we heat home?" Kurumi asks, her voice sounding distant as I start to fade out.
"Don't worry, you'll get another turn with her tomorrow, for now let's take her home and let her rest. She had a long day afterall." Tsubasa says, pulling out and standing up without setting me down. I rest my head against her shoulder and see her smile down at me before I finally pass out.
-The Next Day, Ayako's POV-
"Excuse me! Can I get a picture?" Yet again I flinch slightly and let out a loud sigh. Glancing over at Tsubasa who smiles back at me and nods her head.
"Of course you can. Is there anyone in particular you want a picture of or all of us?" Tsubasa asks, turning to the man with the camera.
"All of you please! Your costumes all look fantastic! Especially that redhead dressed as Futaba, it looks like you stepped straight out of the video game or something." He says, gushing over the skin tight outfit Onee-sama had prepared for me. I knew I kinda looked like Futaba from Persona 5, but I never really thought too much about it. Sure I've played them but I've also beaten most JRPGs for the sake of studying up on building my own games.
"Of course, come on girls, let's get in close." We all get ushered together by Tsubasa and the man snaps a few pictures before thanking us and hurrying off back to where his friends are waiting.
"Do we HAVE to stop every time someone asks for our picture Onee-sama? If we stop for every person asking to take our pictures I'll never get to all the stands I wanna hit up before the end of the convention." I look up at her, pouting hard.
"Aww don't be like that Ayako! They only keep stopping us because you look so stinking cute! And sexy might I add, skin tight clothes look wonderful on you. I wish you'd stop wearing your normal baggy clothes you wear. They are so unbecoming of you." Miku says, flashing her radiant smile at me.
"Oh I don't think that's the problem here Miku. Look at her face, Ayako is practically burning up, you ok?" Kurumi teases, a wicked smirk on her face. I ignore her and keep walking, trying to ignore the sensation of being filled while I walk around. I try to ignore it and continue moving around the convention center, hitting up all the stalls I want to as I go. It's slow going as I am constantly asked for a picture.
A girl bows with a quick thank you as I let her take a picture of me then leaves and I nearly fall to my knees, my face bright red. Tsubasa swiftly catches me and looks at the other two girls with the faintest hints of a smile on her face. "Miku, could you get some water for Ayako, I think we need to sit down for a bit."
Miku nods and hurries off to get some water for me while Tsubasa sets me down on a bench, after a stern gaze from her to some boys hanging out there sends them scurrying away. "Seems like that little trigger you had Miku put in Ayako's head is working pretty well Tsubasa." Kurumi purrs, making me snap my head up.
"W-Wait you had Miku do some sort of mind control on me? That's what's making me feel like this?" I ask, stuttering in surprise that they would do this. On second thought, it's not all that surprising at all after yesterday.
"Not quite actually." Tsubasa says, winking down at me mischievously. "You've actually been walking around with mine and Kurumi's cocks in you all day, and it's been quite difficult to not cum inside you this whole time. Kurumi's cum several times and I had to use portals to keep you from feeling her cum rush into you."
"Wait… then how come I'm just now feeling it really? There's no way I'd be able to walk around this convention with both of you inside me using your powers Onee-sama." I tell her, knowing full well I would lose it if they were both inside me, considering their size.
"Well that's just it Ayako. What we had Miku do was make it so you could no longer feel our dicks inside you, even if we were stuffing you completely. The trigger was any time you got your picture taken, or video recorded and what not, your sensitivity would slowly return to normal, and beyond even. It seems you finally reached your limit." Tsubasa explains, a sly smirk on her face. She stands up right as Miku returns with a bottle of water in hand. "Oh perfect timing Miku, I want you to use Solo on everyone present, have some form a boundary around us, the others will watch as Kurumi and I ravage Ayako right here."
"Yes Onee-sama!" Miku says happily and summons her Angel, instantly taking control of everyone around before I can even object to their plan.
"O-Onee-sama you can't do this! We're in the middle of the Convention Center! I-it's too risky for us to do something like this here! Shido is here too and he isn't affected by Miku's power! What happens if he wanders over and sees what we're doing! I'd be done for!" I protest as they continue to tug at my outfit. Just as they managed to start getting it off with all my struggling, a shrill scream splits the air, causing the four of us to stiffen. I look at Tsubasa who just nods her head. "I need to look into this Onee-sama."
"I know Ayako, Miku remove the hypnosis for now, good luck Ayako."
"Shouldn't one of us go to assist her?" Miku asks as I rush off in the direction of the scream.
"We'll watch for now, if she needs us we can step in, but I prefer to let Ayako fight her own battles." Tsubasa says, crossing her arms as she watches her sister's back shrink and vanish from sight.
