the damned collab
Inko is flustered when Mitsuki picks up the phone. She hasn’t sounded this flustered since she talked to little Izuku about the birds and bees. (Which Mitsuki followed up in a much more blunt and informative manner for both the boys once they hit high school.) But that was years ago, the boys have been out of school for what, four years now? Five? Fuck we’re getting old.
“What is it, Inko?” She’s always been so emotional and easily flustered, something that Mitsuki has been known to take advantage of.
“Well, Izuku has been staying here with his girlfriend over the weekend. And I was just doing my laundry- mine not theirs- and when I was folding it, I found…” she trails off into a blubbering mess but Mitsuki is quick to get her back on track, asking her to repeat that. “Well, um, I found her orange thong.At first I just thought it was a hair tie! You know one of those lacy frilly ones because it was so small but when I picked it up I figured it out! Oh this is so embarrassing, how do I just give them back! She's still here in Izuku’s room while he’s at a last minute meeting so I can’t sneak it back in their clothes.”
Mitsuki doesn't hide her laughter. This is only something Inko would get worked up about. As if they hadn’t owned skimpy garments like this back when they were younger. Hell, Mitsuki still has some stashed away for special occasions and she would better her bottom dollar so does Inko. “You could just give them to her. You know that right?”
Inko is adamant in her denial that she can absolutely not do that. Mitsuki comes over, with the intention of distracting Izuku’s girlfriend so Inko can sneak upstairs. But when she sees you over Inko's shoulder through the doorway she stops with her mouth hung open. You see her whisper something to Inko as you wave and continue into the kitchen to take out the cookies you were baking.
“Give me the underwear.”
Inko gasps, “What! Why! What about the plan?” She glances over her shoulder to make sure you couldn’t hear.
Mitsuki’s face is adorned with a grin reminiscent of Katsuki in battle, “Wanna make her squirm and blush. Bet she’d be cute. Mostly want to make sure she’s good enough for your darling boy though.” Inko doesn’t need to know that she does want to make sure you’re good enough for Izuku, but not in any way Inko would ever dream of. As Inko shoves them in her coat pocket, Mitsuki says loudly, “Oh shit, Inko! I forgot your apron at my house. Let me go grab it real quick and I’ll be back. Just give me five minutes.” Neither you nor Inko get another word out before Mitsuki runs off in a manner much giddier than you’d associate with the hot-head’s mother.
True to her word she returns, apron in hand and a grin on her face. She shoulders past Inko and meets you in the kitchen where she starts making a pot of tea for the three of you. “So darling, we’ve met but only in passing! How did you and Izuku meet?”
It’s funny how much she is like her son, forward and vexing in what you might call an endearing way. “Well, I work in the support department at the boy’s agency. I worked on Katsuki’s gauntlets a few times before Izuku came down for a boot redesign. He caught me mumbling and we just.. Hit it off I guess.” Mitsuki watches you smile and gesture around at nothing. ”Coffee turned into dinner and that turned into dates. It just kinda happened. And here we are eight months later and in a happy open relationship.”
“Well I’m glad for the both of you, you seem really happy. Maybe you can find someone for my brat to shackle down with. That’s probably asking too much of you though, we all know that he’s a lot to handle.”
You giggle at her, mischief in your eyes, “I think he’s got his eyes on someone, but his head is stuck so deep in his inferiority complex so it might be a while before anything happens.” Mitsuki files this away for later questioning but leaves it to rest for now.
“Well, let's take these cookies and tea to the living room and we can get to know each other a little more, yeah? I got plenty of embarrassing stories about those kids.” You follow her into the living room and meet Inko who is nervously sitting on the couch, eyes flickering between the two of you.
They watch you sit, carefully crossing your legs in your cute pink sundress before smiling up at them and asking how they met. Mitsuki regails you with some story that you're sure is more false than true but is entertaining nonetheless. It isn’t long before Mitsuki is asking you about your “dirty little secrets.” It catches you off guard, causing you to chuckle and ask just what she means by that.
“Well, I was a girl your age once, what do you get up to that Izuku wouldn’t want his mother dearest to know? It’ll just be between us girls.” It’s an uncomfortable question, north hat you are ashamed about your sex life, its realtively healthy and normal, but nothing you’d want to share with his mother of all people.
“Uhm, I’m not sure what you mean Mrs. Bakugou.” That smile returns as she pulls something out of her pocket, some type of fabric? Oh. Oh no. The cheshire grin on her face is juxtaposed by Inkos beet red embarrassed face and you just know she found them. “I am so embarrassed. I know it’s just underwear but I’m sorry you found them Inko! God this is so awkwa-”
“This isn’t even enough to be considered underwear. There’s barely any fabric here. I bet you wear these when you want Izuku to bend you over.” Mitsuki’s gaze is appraising, reading your body language, the heat in your checks, shifting of thighs and averted gaze. She must like what she sees because she continues. “Then why did you bring them wiht you here, did you want him to fuck you in his childhood bedroom? Did you suck his dick while his mom was home?” You don’t answer and she looks to Inko, “Well, did you hear anything that you wish you hadn’t? Hear her cute little moans maybe? Filtering through your bedroom wall while you try to sleep at night?” The greenette is staring down at her lap, red cheeks evident to all.
Somehow this woman in front of you has transformed into a demon and has both you and your boyfriend's mother under her thumb. Playing with you both like little dolls for her entertainment. She Stands up and stalks over to you slowly, dropping the lace on your lap and waits, glancing between you and the fabric. You swallow and stand up to pull them on underneath your dress.
“Oh ho ho. Was this naughty little girl prancing around the house in this short little dress, entertaining her bosses mothers with no panties on?” You feel compelled to nod, like your body is moving without your approval as you lift your dress up to show the snug straps over your hips and small triangle of lace covering not much of anything. Mitsuki lets out an appreciative hum, motioning for you to twirl. A harsh smack lands on your ass as you comply. You see both of them watch it jiggle as you look over your shoulder scandalized at the action.
To be honest you aren’t surprised at Mitsuki, not with the way she was just walking, but Inko? Sweet little Inko who’s been nothing but an angel to you the whole time you’ve known her? No, you didn;t expect her to be staring at your ass in the same way her son does when he sees that little string swallowed up by your cheeks. You go to let the fabric fall and leave, overwhelmed with what's going on but Mitsuki is already behind you, hands running up your body and dragging the cotton fabric of your dress up with it.
As she pulls it over your head, you are staring at Inko with a mixture of lust and confusion as your tits fall free, bare for her to drink in. You should be embarrassed, standing near naked in front of these two mothers, mothers of our bosses, your boyfriend's mother. But the attention they are giving you, like your a gift, the apple of their garden, forbidden but ripe for the taking.
It makes you feel desired, powerful, someone who could hold all the control if you wanted to. Like you could control Inko, twist her around your finger every which way. That you drew this type of energy out of Mitsuki, it’s a heady drug. Like a goddess, of the dark seedy underworld where mothers lust for you but in the same breath of spring, a fresh breath of air, a light playful thing, mischievous and fun.
Mitsuki pulls you out of your staring contest with a snap of the strap on your hip. You turn back to see her in her sleek black skirt and a black lace bra looking just the picture of elegant beauty and power. And the gleam in her eye as she looks you over with a smirk makes you realize that you have no power here. The small warm hand on your hip just cements the fact. You are powerless between the two. A charming devil on one shoulder and a doting angel on the other.
Inko is hesitant in the way she touches you, unsure in what is allowed but desperate to push the boundaries and just take. The soft kisses along your shoulder blades are evident of that. In between the ones she's leaving you and Mitsuki’s long fingers teasing your nipples you find yourself walking to Izuku’s room and sitting on the bed. Inko and Mitsuki are looming over you and you try to figure out where this is going next but so far just letting it happen has been more than fun.
Mitsuki slaps Inko’s ass and tells her to see how good she kisses, see if she treats her little boy right. Inko is more than happy to comply, scrambling up into your lap and pushing you down into the bed. Her lips are small and soft and pleading for more. You open up her mouth and she honest to god moans as she slips her tongue in. You can feel Mitsuki unbuttoning Inko’s shirt, undressing her as she’s sitting on your lap. GIving you the most twisted present you could ever want. All this soft skin for you to touch, to kiss, and worship like the angel she is.
She whimpers when Mitsuki pulls her skirt off, leaving her in her cotton underwear and plain bra and all you can focus on is the wet patch you can feel growing from her crotch pressed on your stomach. You see her kiss swollen lips and pupils blown wide. It looks like there’s some type of regret trying to cross her features but when you grasp her ass and drag her cunt along your stomach it fades away with eyes rolling back into her head.
Mitsuki kneels down to whisper in your ear, “Doesn’t she look so pretty like that. Moaning like a whore from a little action. Don’t you want to hear more of those pretty noises?” You nod, looking up at her like she hung the sun, ready and willing to do what she asks. You can feel inko rocking her hips against you, a hand grasping your tit for balance.
You look at Inko, begging her to tell you what she wants, more than willing to give it to her. In the end, neither of you make that decision. Mitsuki pushes her up your chest until she straddles your shoulders. Inko tries to shuffle away rambling about how she's concerned about hurting you or being too heavy but your arms are already wrapped around her thighs and lips leaving bruising marks right alongside them.
Her legs are coated in arousal and your spit before Mitsuki slowly pushes her down onto your tongue after catching her by surprise with a kiss. You can taste the arousal caught in her panties and the warmth of your tongue makes her let out a yelp that turns into a moan. You chuckle and press a kiss against the fabric before you nudge them to the side with your nose and dive in with a fervor.
Her weight pressing down on you feels like heaven, you must have died and moved on and the noises coming from above you are the trumpets at the gate, angels welcoming you home, something ethereal. Your tongue tasting the rivers of milk and honey pouring from her as she ruts against you. It’s intoxicating and you forget about your corporeal form until a pair of hands spread your legs apart for someone to move in between.
Mitsuki’s touch lights a fire in your gut, fingers dipping into your hole quickly before pulling out. You can hear a muffled laugh and she’s so wet from making you feel good. Isn’t she a good little girl? It’s shameful, the way your gut clenches and flops at her words, the consent making you queasy but the doting tone willing you to agree.
A blunt head is pressed against you and stays right there, teasing you with what is to come but never giving in. Rolling your hips doesn’t help to fully catch it in your hole but it must be a pretty enough sight for her to give in and bottom out in one sharp thrust at jolts you forward.
Inko almost falls over but a firm fist in your hair keeps her upright and chasing the pleasure. Mitsuki’s sharp and near brutal pace makes it difficult for you to focus on Inko but you have to. Have to keep hearing all those pretty sounds. You focus on suckling at her clit, flicking at it with your tongue before sliding down to press at her hole. You slide in easily and with every roll of her hips your nose catches on her clit causing them to stutter.
You can tell she’s close and nothing in the world could stop you from bringing her there. Your wet and sloppy but its doing the triick, slurping at her folds, thumbing at her clit while you fuck her hole with your tongue, it doesn’t take long before theres a waterfall of ambrosia pouring down your face and Inko falls over next to you boneless.
Mitsuki must be proud of you or happy that all your attention is on her, either way she gets into your space and licks Inko off of your face before grasping your jaw open and spitting in your mouth. “Hold it. Mouth open.” You do just that and she nods looking at that little fuckdrunk look on your face.
She picks up her pace, fucking you fast and fucking you stupid. Inko’s mouth latches onto one of your nipples catching you by surprise and a weak whine slips out. She coos, “Aw a cute little baby. I get why Izuku likes you, lookin’ up all doe eyed while being fucked open. I know I love it. Love how tight you are around my cock. Fuck, darlin’.”
You feel like lava is flowing through your veins, fire licking at your lungs, your brain leaving it scorched until nothing is left but her. Your throat is dry and you want to cry out, let out the noises building in your chest but you have to be good. Keep her spit in your mouth until she tells you to swallow.
Inko’s hands are joined by Mitsuki’s roaming over your body leaving nothing untouched. You are a live wire ready to overload and shut down. Soft fingers rub against your clit beckoning forward the black out and it's just as strong as you expected, A supernova of pleasure from the mused hairs on your head to your curling toes rippling out from where Mitsuki fucks you through it.
She doesn’t stop even when your back hits the bed again. Her pace slows but it doesn’t matter when every thrust burns as you try to scramble away from the cooling embers of pleasure that's quickly turning into white hot pain.
You feel her shudder and grind in against you and let out the softest noise any Bakugou has ever uttered and it’s an entirely enchanting moan. She rolls her hips through her organs, riding through the pleasure on the straps of her harness before she pulls out and stands on shaky legs. Only then does she let you swallow.
Inko shuffles away quickly, urging her to sit and returns with some wet cloths. She dutifully and delicately cleans both of you up, showering you in praise and soft kisses against the cleaned skin. Mitsuki grumbles far more about the words than you did but puts up no real argument.
The three of you lay on Izuku’s childhood bed for longer than you probably should. The door opening was near inaudible but Izuku’s loud call for the both of you shatters the silence your trio was basking in. Mitsuki and Inko hurriedly dress to meet him downstairs and buy you some time to regain your senses and put your wracked self back together.
You see Mitsuki stop by the door and you drearily turn your head to look at her. “For what it’s worth, I think you probably treat Izuku pretty well.”
