[dddomenstarstwst1]

Hi! Can I request puppy play with a sub!male and a dom!mean reader? Some dacryphilia and a muzzle would be nice :)

Oh yes, please! I love me some puppy boy ♡ Thank you for requesting!

Bad Dog

Warnings: sub!character, dom!gn!reader, mean!reader, puppy play, dacriphilia, muzzle, implied brat!character, stepping, dry humping, hair pulling, titles (master, used once)

a/n: the character is unspecified, but is still depicted as 18+ y/o. I've added a list of characters i had in mind while writing it, you can see the in the tags. You can still imagine your fave, tho!

"What's that? You're crying?" You watch as hot tears run down his cheeks, small sniffles escape him. With a 'tsk', you brush strands of hair that block his face, "You're always all bark, and no bite. It really takes me just a bit of harshness, and you're already turning into a whining dog in heat."

He desperately shakes his head, but not in attempt to disagree with your last sentence, no. He tries to prove that he is capable of biting alright, yet the muzzle you put on him doesn't allow that. Your fingers trace the metal cage, pleased with his pouting expression.

"How about you prove how good you can be for me, let's say, by..." your foot presses against his clothed semi-erection, ripping out a startled whimper. He doubles down, hugging your leg with his arms, eyes trained on your face, "...making yourself cum by humping my leg, hm?"

"What?! You know I can't come, if you don't touch me! You better give me proper attention, [Name]!" He huffs, looking offended by your "dumb" suggestion. You're well aware of how he gets, when you try to put him in his place, trying to appear dominant. His attempts always fail, however.

"Cute. Very cute." You run your hand in his hair, tugging at his messy strands. You look him up and down, his mouth open in a silent moan. "Cute, yet so desperate. Are you not?"

"N-no! I'm not desperate, you are– Ah!" You give his hair a one more harsh tug, which shuts him up completely. "Shut your damn mouth and be a good boy for once, or else I'll make sure you won't get to have any orgasms for a whole week."

"Yes, master..." You nod along his words, petting him in a rewarding manner. You like his feistiness, but his obedient side has a unique charm to it. You press your foot on his still clothed dick, before slightly lifting it. "Hump my leg."

The words sound authoritative, no room left for his brattiness. He hesitates for only a couple of moments, but slowly wraps his arms around your thigh, while his bottom half ruts against your shin. You can't help teasing him by brushing your fingers in his locks.

His movements turn into erratic ones, rhythm lost completely. He turns his head to the side, pressing the muzzle to your leg, as frustrated tears form in his eyes. He blinks, and they start streaming down his flushed face.

"Poor thing, let me help you," you free him from the cage, massaging the spots it connected to. "Don't stop moving. If you make yourself cum like this, I'll reward you." You kiss his temple, urging him to get back to work.

Your dog might bark a lot, but he will never bite the hand that gives him pleasure.

I subbed this bit from today's live stream I thought was really funny. I love Knights' seiyuus so much.

[normalestenstars]

thought: i think it's easy to get mad at people for not understanding your favorite character in a non-malicious manner, but if you think about within a bigger scope... enstars currently has 50+ characters, and 400+ stories. not to mention, the stories themselves are known for being long, long, long reads. it's unrealistic to expect the average fan to know the lore of every single character, especially if they only produce a unit or two

i don't disagree with the fact that people flanderize characters all the time, but honestly... this is not an enstars fandom issue. it's an every fandom issue. shallow engagement tends to lead to shallow interpretation of characters. either way, the point i'm trying to make is that if these polls make you annoyed then use them to lore dump about your favs! using myself as an example, i personally don't have the time nor interest to delve into a lot of the cast, but i like hearing people explain them!

“Good wolfie” - Koga Oogami/gn!reader

Cw: Dom Reader, sub koga, dry humping

Small Drabble idea

Thinking about koga mindlessly dry humping his producers butt as they’re leaning against one of the desk in the music room. His brain having gone full puppy mode as he whines into his producers ear, his producers face a soft shade of pink/red as they praise him, telling him how good of a wolf he is for taking pride in claiming what’s his. Allowing the idol to leave hickeys and bite marks along their exposed neck as he comes closer and closer to his release. “Remember, good wolf boys ask for permission before cumming.”

Vampire Siblings

Writer: 日日日 (Akira)

Character(s): Isara Mao, Sakuma Rei, Sakuma Ritsu, Anzu

Translated by: jewwyfeesh

Disclaimer: I translated this story from the CN version of the game, which means that it has been double translated (JP > CN > EN).

Rei: Oooh!! Ritsu!! GOOD~ MORNING~ ☆

Season: Autumn Location: Track and Field

Mao: Mmm~ The feeling of fulfillment after a good prac! It’s really amazing~ ☆

Oh, thankies. Is this isotonic drink for me, Anzu? You’re becoming more and more ‘Producer’-like with every passing day~

Seems like you’ve been running after lots of other units besides us Trickstar lately.

There there, you’ve worked really hard ♪

But yeah… even though I’m one to talk, I still think you should take care of your body and your schedule. I’d feel really guilty if you pushed yourself too hard and something happened to you.

Never mind. Let’s go home, Anzu. Today’s my turn to ‘send you home’, so I’ll make sure that you get home safe and sound.

Though… lately, it seems like I’m always the one sending you home…? To the point where I’ve even gotten to know your family fairly well.

Sometimes I’d even stay for dinner…

But I’m not complaining. My family’s the kind to do whatever they want. As such, we don’t really spend a lot of time together. So… It’s nice being with your family.

I wonder if it’s because I can do things like household chores all by myself?

Everyone tends to think, “Oh it’s fine if we leave Isara Mao alone, nothing will happen to him”, but my younger sister has always been coddled and spoiled by our parents…

Hmph, would it be better if I tried to act a little more spoiled? But the second I come back to my senses, I’m back to taking care of others again. I feel old.

You’re also someone like this, so please be careful. You can also lean on me sometimes, you know~?

Eh… I’m meddling in other people’s business again…

It’s about to become a bad habit of mine, forget it, forget it… It’s pretty good to be relied on by others, but I’ve been ‘like this’ since I was young.

It’s because of Ritchan, my childhood friend~ If I leave him to his devices, that guy literally won’t lift a finger to do anything. When it got to a point where I couldn’t stand it anymore, I could only go and help… I’d help and help and help till I became ‘a meddler and a half’ ♪

You know Ritchan, right? Knights’…

Ahh, so you’ve also taken care of him before. He’s always so lazy, you literally can’t ignore him~

…Eh? You’re saying Ritchan’s over there?

Ah, call for the cat and he shall appear… where is he~?

Ah! Goodness! This guy, sleeping outside without a single shred of protection!

One day you’re gonna get pickpocketed, what are you gonna do then…? I reckon he fell asleep after lunch, and slept ‘all the way’ till now~

HEEEEY— Ritchan!! Don’t go sleeping in places like these, you’ll catch a cold ya know~?

Ritsu: ……Mmhhghhh? Huh… Maa~kun…? Wh… don’t wake me up…

Mao: Of course I need to wake you up. The school gates are gonna close soon, and if we don’t get moving we’ll be locked in. Our school has always been particularly ‘strict’ about these kinds of things.

Ritsu: Eh~ …Well, whatever. I could just continue sleeping here and save myself the trouble of having to come to school tomorrow. The more I think about it, the better of an idea it seems~

I’m really sleepy, so just leave me be. No matter how much I sleep, it’s never enough…

Mao: You… you haven’t changed one bit…

Hm? Eh? What are you hugging? It’s not a bolster… right? A tree stump? No, that seems to be a person…?

Ritsu: What?

Rei: Huu… snzz… ♪

Kekeke… Little baby~ Be good~ ♪ Go sleep~ ♪ Uuuu ♪

Mao: Ahh~ Taking a closer look… isn’t this Ritchan’s older brother? Why are the both of you snoozing together? Seems like you have a really good relationship~

When I got to know Ritchan, this person was always overseas, so I didn’t get to know him very well.

To be exact… I only found out he existed after I enrolled in Yumenosaki Academy. Ritchan doesn’t talk about his brother very often, so I got a little worried…

Who knew that the both of them were actually so close ♪

Ritsu: …Maa~kun, do you have anything sharp? I think staking him in the heart would definitely kill him.

Mao: N-no, you can’t just go around killing people. Eh? Do both of you have bad blood? In that case, why are you sleeping next to each other?

Ritsu: I don’t know what this thing was thinking, nor do I have any interest in finding out…

More than anything, I want to bury this thing six feet below and wipe my hands of it ‘as though nothing happened’. Now. Immediately. The faster the better.

Rei: E-eh? What happened, is it already time to say “good morning”? Ah? Where am I?

Ritsu: Yo. Why are you sleeping next to me, huh? You reek of mould, so stay further away from me. What happened, how are you still alive?

Rei: Mmmhh… My mind’s all fuzzy just after waking up… don’t ask so many questions at one go…

What’s there to rush, hm…? Re-rest a little… yawwwwn… ♪

Ritsu: No. No sleeping. I’ll kill you.

Rei: This tone… one that shows no mercy, even to one’s own blood brother…

Oooh!! Ritsu!! GOOD~ MORNING~ ☆

Ritsu: Don’t hug me! You’re so annoying!

Okay but spit it out. Why were you sleeping by my side? Depending on your answer, you could be demoted from “someone who seemed to have been a brother previously” to “stupid bug”.

Rei: Even if you don’t demote me, it’s a bit much, don’t you think?

Nothing much… It’s just that when I was leaving for home, I happened to see Ritsu sleeping. I was worried that you’d catch a cold, so I used my body warmth to warm you up. This is a big brother’s love ♪

Ritsu: Is that so? I understand, you don’t need to say anymore. Complete waste of Earth’s oxygen.

Maa~kun, could you help me get some cement from the warehouse? I want to solidify this thing in there and let it sink to the bottom of the ocean.

Rei: We’ve just woken up, and yet Ritsu’s already trying to get rid of me!?

Mm~ Anywho! The elderly aren’t quite suited for outdoor camping… My whole body’s sore and stiff…

Ritsu~ could you help massage my shoulders please ♪

Ritsu: Didn’t I tell you to shut up? You stupid bug.

Mao: Okay okay… as brothers, you guys should try to get along well. Though, let’s leave the fighting and the shoulder massage aside, yeah? We’re really about to be locked in school.

Rei: Oooh, you’re from Trickstar… It’s already this late… Thank you for waking me up. Ritsu~ it’s been a long time since we brothers walked home together hm~?

Ritsu: Brother? I don’t have a brother, though?

Rei: Don’t deny your brother’s existence with such a deadpan expression… That’s a bit much, even for a younger brother, don’t you think? I’ll start crying…

Ahh, I can’t… My tear ducts are getting weaker as I age… Uuuuuu~

Mao: Ahaha, I think I kinda understand your relationship, Sakuma-senpai.

Ritchan, the more you talk, the more others are gonna think “oh he’s just in his rebellious phase”, so maybe it’s better to not talk altogether?

Ritsu: Damn it… That isn’t the case at all. I had only wanted to throw this annoying ass thing into the trash bin. Whatever, it doesn’t matter anymore.

Maa~kun, you want to send them… send the Transfer Student home, right? Hurry up and go, don’t worry about us.

Rei: Mhm, please be careful on your way back. Who knows what kind of demons will be roaming at this hour – for example, vampires… and the like… ♪

Mao: Yep. I’ll be careful. The both of you too; no more fighting, okay? Hurry up and go home~

Rei:

Mm, I’ve always been praying that I’ll have a close relationship with Ritsu! We’re brothers after all ♪

…Ah, Ritsu? Where did you go? Hey— Ritsuuuu~

Ah, he dashed off at the speed of light. He really does hate me, huh? Hehehe ♪

Wait a minute, I am also more active at night! Well, when it comes to hide and seek, I’m not about to lose to a ‘novice’ ♪

Aaah… Running around like this under the night sky, it really reminds me of our childhood ♪

Ritsu: D-don’t chase after me!! Didn’t I already say you’re annoying!? Did it completely fly over your head, you infuriating Anija!?

Rei: Excellent, excellent… he’s finally willing to acknowledge me as his brother. Anyways, we take the same path back home, my super duper adorable little brother…

Translator's notes: [1] The original CN term here is 「菜鸡」, slang for "complete, total noob". I translated it to novice, a synonym. Personally don't think Rei would call Ritsu a "noob".

Nagisa Ran - Eden's Christmas Party ①

Writer: Yuuki Yoshino

Season: Winter

(Setting: Adam's Private room, Jingle Bells is playing in the background)

Ibara: Your Excellency~! Come, let’s celebrate Christmas! It’s called Jingle Be~lls!

Nagisa: …… Christmas. Is Christmas delicious?

Ibara: Ahaha ♪ His Excellency says some interesting things!

You could say that Christmas in Japan is delicious since it’s celebrated with cake! Do you like cake, Your Excellency?

Nagisa: …… I don’t know. I would eat it if it were served but if you asked me if I liked it or not I wouldn’t be able to say.

…… Incidentally, Ibara, why are we dressed like this?

Ibara: Ahaha ♪ Is that what His Excellency was wondering about?

Oh, how rude of me! I will do my best to answer your question! Salute~☆

Ibara: The other day, His Excellency asked “What does a Christmas party entail?” so I prepared to liven things up in my own way!

Nagisa: …… Is that so? Sorry, I can’t recall.

…… But Ibara remembered and prepared. Thank you. 

Ibara: No, not at all! Cake and food is available but if it’s not needed we can toss it in the trash!

Nagisa: …… After you went through the trouble to prepare it, it’d be a waste to throw it away.

…… Ah, Ibara. Look outside, it’s snowing.

Ibara: Ah, this is magnificent! What a perfect situation! No, it’s romantic!

However, it’s inexcusable that a filthy person such as myself is watching this with you! Please excuse me while I go jump out a window!

Nagisa: …… No, I don’t want you to do such a thing.

…… Ibara, I’m happy to celebrate Christmas with you like this. And I hope you feel the same way.

Ibara: Of course! I’m truly lucky to be able to celebrate Christmas with His Excellency……☆ Here, have some cake~!

Nagisa: …… Thank you.

…… Ah, how pleasant.

Hey! Could I request some sub!virgin chiaki please!! maybe reader giving him his first orgasm

Virgin!characters are such a treat 😋 thank you~

First Time (ft.chiaki)

Warnings: sub!chiaki, dom!gn!reader, handjob, virgin!chiaki, praising, begging, pet names

a/n: character is depicted as 18+ y/o

He was sitting between your legs, back to chest, naked body squirming under your touch. It was hard to get him to this point, Chiaki never had sex, he confessed to you. So this was all new territory for him, and you were keen on making him feel good.

Nothing too serious for his first time, just a simple handjob from you would already probably be too much for the poor boy. But he agreed, quite eagerly, and that's how you ended up like this.

"It's okay, bunny, I'll make sure you feel good. Just tell me if you want to stop, and I'll stop," You draw comforting circles on his inner thighs, earning a small whine from him.

Your hands on him were enough to drive Chiaki mad, it didn't help how you pressed against him and whispered sweet praises in his ear. And the way your fingers wrapped around his tip got him throwing his head back against you.

Sure, he jerked off sometimes, but it wasn't the same as having a person you love do it for you. There was some sort of intimacy Chiaki couldn't fully comprehend yet, and you didn't give him time to. Your hand moved up and down his length, stopping at the base to give it a squeeze, then continuing to move.

"Feels good, baby?" He lets out a string of moans, and you see his toes curl as he struggles to keep his legs open. He wants to curl in on himself so bad, so desperately he wants to get away from your hand, embarrassed by how he looks and sounds.

Yet, he keeps himself spread for you, seeking your praise, seeking your touch. He gasps when you call him 'your good boy', he whines when your thumb slides over his slit, collecting some precum.

"Mn- clo-ose!" You want to tease him so bad, want to prolong his orgasm, but decide to leave it for later. You'll have many chances to corrupt his body and mind.

"You can cum whenever, sunshine," You focus one hand on his tip and the other on his shaft, leaving light kisses on his neck. He won't last long, both of you know it, and before he can warn you, Chiaki finishes all over your fingers with a strangled moan.

His body goes limp against yours, breath heavy. You coo at him for being so good for you, letting your hands massage his legs. After composing himself, he turns his head to look at you.

"That was– You were amazing. Can we do it again? Right now?"

He'll put you into a grave, that's for sure.

Resurrection of Soul - game cut (eng tl)

Key: Rei, Kaoru, Koga, Adonis, All

Trapped in a deep sleep, as if frozen still

The moment you’re touched by that voice

You’ll surely be resurrected

Tonight, Back to the dark!

Shout! Your desire from your heart! It’s a soul of UNDEAD.

The cruelty of time

(Tear up your heart.)

And even the forgotten memories you seek

Engraved firmly and deeply

(Claw marks remind you of the melody.)

The melody that resounds in the dark

Is something that cannot be erased

The veil of darkness called solitude

Is like a Flashback that’s been torn to pieces

(Every nightmare! Sing out tonight! As you wish!)

“Because it doesn’t matter even if I fall”

The painful memories makes me scream

To you who were asleep as though frightened

I’ll give you a kiss of awakening

(Resurrection of Soul)

Once again, at the end of your heartache

Resurrect Your Soul

Every time I feel love freely

It’s like a dizzying pleasure… Flashback

(Every nightmare! Sing out tonight! As you wish!)

I don’t mind even if I fall

A piercing voice sings with joy

To the soul that has been sleeping deep in fear, I’ll give a kiss to awaken it

(Resurrection of Soul)

Now, at the end of heartache

Love is resurrected

(Tonight we unite our darkness!)

Tea Garden

Writer: 日日日 (Akira)

Character(s): Tenshouin Eichi, Sakuma Ritsu, Shino Hajime

Translated by: jewwyfeesh

Disclaimer: I translated this story from the CN version of the game, which means that it has been double translated (JP > CN > EN).

Ritsu: Ah~… Don’t just stand here yapping away, hurry up and go~ Your monologues always drag on for waaaay too long.

Season: Summer Location: Yumenosaki Academy Garden Terrace

Hajime: Hey everyone~ ♪

Sorry for being late, I got held up due to my part-time job on campus…

Though, thanks to Transfer Student-senpai’s assistance, we were able to wrap it up quickly ♪

Ritsu: Hello~… Uuuu… The weather’s really toooo good, I’m getting such a wonderful headache from how good it is…

Hajime: Ah, there should be some umbrellas over there. I’ll go grab one ♪

I’ll brew some tea on the way, too~ Ritsu-senpai, is there anything in particular you’d like to have?

Ritsu: Ah~ …Since Anzu’s here, I’ll pass on the drinks. Whenever I get thirsty, I’ll just have a sip of her blood.

Hajime: Eh, you can’t drink blood.

It’s not hygenic~ How about having some black tea instead ♪

Ritsu: Mmmh~ I’d feel like going to the toilet if I drink tea. But I’m trying not to move around too much…

Ahh~ I’m too lazy to move today. It’s sunny every day.

Hajime: Ehehe. Is this not a ‘good thing’? If it’s sunny, our laundry will dry faster, so I think it’s pretty nice ♪ 

Eichi: Hajime-kun, Anzu-chan, how about the both of you take a seat first? I’ll prepare the tea and snacks.

Hajime: Ah, there’s no need! I can’t let the Student Council President do such odd jobs!

Eichi: Kindly refrain from addressing me with an excessively formal [1] title like ‘Student Council President’.

Please do away with the formalities; let me steep the tea. After all, is this not part of Tea Club’s activities ♪

Ritsu: Ecchan, the snacks I’ve made are in the kitchen fridge. If everyone’s okay with it, we can have them with tea~?

Eichi: Hehe, even though calling me ‘Student Council President’ is too ceremonial and could even be considerred flattery, calling me ‘Ecchan’ is also a little too… familiar[2].

Then again, Ritsu-kun had to repeat a year. He was meant to be in the same year as I, so I suppose it doesn’t really matter.

Though… trying to find the perfect balance between ‘authority’ and ‘approachability’ is extremely difficult. Anzu-chan, you agree, don’t you?

I’ll head over to the kitchen now. I’ll be back promptly, so please feel free to take a break.

Aha, ‘serving’ others is actually rather fun… ♪

I can drop the heavy title of the student council president and just be myself… times like these are really hard to come by. Tea Club’s activities are a great way for me to relax ♪

Ritsu: Ah~… Don’t just stand here yapping away, hurry up and go~ Your monologues always drag on for waaaay too long.

Eichi: Hehe, my sincere apologies. Without further ado, I shall now take my leave. Farewell ♪

Ritsu: Byebye~ …Ha~kun, Anzu, there are chairs over there that you can use~ It’s kinda stressful to see you standing around you know?

Hajime: Achoo, please excuse me. Ahh, finally… the feeling of being alive. Inhale… exhale… I feel really relaxed~ ♪

Ritsu: Ha~kun, you’re not allowed to take out that fragrant thing when you’re next to me~ The second I smell it, I immediately feel like falling asleep…?

Hajime: Ahaha. Lavender does have a sleep-inducing effect~ My bad ♪

Though… Ritsu-senpai, you’re always sleeping… I heard that if you sleep too much, your braincells will die~

Ritsu: Ahhh, no wonder I’ve been so forgetful lately. So this was the reason… Eh, it doesn’t matter, sleeping is pretty comfy. If I sleep during the day, I’ll be awake at night, and vice versa.

Hajime: Is that so~ You’re such a night owl.

Flipping your sleep schedule is really unhealthy… I think it’s still best if you don’t consume so much coffee…

Eichi: If I may interrupt — upon evaluation of your lifestyle and habits, Ritsu-kun, I’ve prepared some kudzu root soup[3] for you, as it seems to me that your body isn’t in the best of conditions these days.

Ritsu: But I’ve always been like this though.. Ahhh… this flavour is… really… too special, I don’t like it~

Fizzy fruit juice would’ve been fine.

I’m gonna eat some of the snacks I made to clease my palate. Om nom nom ♪ 

Eichi: The designs of Ritsu-kun’s desserts are rather avant-garde…

To be honest, one would find that they are actually really delicious after eating them, but I would have to muster a lot of courage to even take the first bite. I don’t think this is particularly cordial?

For Hajime-kun, I’ve brewed some vanilla tea – that’s alright with you, yes? Anzu-chan and I will be having Oriental Beauty Tea, I hope it’s to your tastes… ♪

Hajime: Ahh… it’s some high-end tea leaves again… One cup like this is practically equivalent to my entire income from working part-time in school~

Eichi: Fufu. Only food of the highest quality should be consumed.

The food of today maketh the body of tomorrow. This is but an investment for the future.

I have to pay extra attention to my diet due to my sickly body… so I am rather envious of people like you who can eat just about anything you fancy.

Ritsu: Ah~ …If you wanna live forever, I can turn you into a vampire~?

Eichi: Even though I am interested in the vampiric lifestyle, I still wish to continue being an idol. Come on, everyone, please make yourself at home and have a drink.

Today, there are more people than usual – the atmosphere is a lot livelier and fun, so I’m really happy.

You too, Anzu-chan. You’re welcome to join us Tea Club anytime ♪

Ritsu: Yeppu, I agree with Ecchan on this. Even though I tend to hate noisy environments, but when tea is drunk with everyone around, one would feel even happier.

Let’s host a Mad Tea Party in your dreams too… ♪

Translator's notes: [1] The original CN term used is "见外", which means to "treat someone as an outsider", or "to treat someone with formal courtesy as accorded to a host or guest".

[2] The original CN term used is "熟络", which means "familiar / close". Generally speaking Asian countries places a lot of importance on treating your seniors with respect, and using an informal nickname to your superior isn't the most respectful thing LOL; however, you can call people of the same age as you or younger than you by informal means. Ritsu is in year 2 and Eichi in year 3, which means that on paper Eichi is his senior and should be addressed as such (ie. -senpai). So that's why Ecchan made that remark -- which implies something like "don't address me like that, we're not that close / we're not in the same year". But afterwards he lets it pass because Ritsu did get held back LMFAO so in theory Ritsu would've also been in year 3. Read Black Tea - A Spoonful of Sweet Poison 5 to find out more about the origin's of "Ecchan"~

[3] Kudzu root soup... Kudzu "is an herb used in Chinese medicine to treat alcoholism, heart disease, menopausal symptoms, diabetes, fever, the common cold, and neck or eye pain. It is sometimes used in combination with other herbs, [and suggested to have] anti-inflammatory and neuroprotective properties." (Memorial Sloan Kettering Cancer Centre - Information about Kudzu).
