Story 2: Breaking The Boundary ( Part Four of Five )


As the sinful acts between mother and daughter ensued, the incestual pair moaned into their intense lip lock as Katsumi rose to her knees, Mitsuki moving with her as she didn't dare risk breaking the heated and forbidden kiss, not that she wanted to or could. The feeling was mutual as Katsumi didn't hesitate to pull her Mother towards her, forcing her over her lap. Her right hand came around the blonde woman to catch her by the ass cheek, grasping firmly when slapping her palm over her plump flesh. As a result, Mitsuki squeaked in delight.

With her left hand, Katsumi tossed her bathrobe aside after stripping it from her body, seeing no point in hiding her curvy naked form any further since they're officially passed the point of no return. Now that nothing kept their skin apart, Katsumi groaned hungrily as she pinned Mitsuki down to the bed once more, their marshmellow soft tits mashing together. Katsumi showed no restraint as she put her tongue game to the test with the intention of making her Mom submit, playing with Mitsuki's own moist appendage competitively. One way or another, the teen will make this slutty MILF hers. As for the time being, Mitsuki wasn't her mother, but simply a sexy plaything that lived solely to 'entertain' her.

Her body consumed in sexual heat, Mitsuki groaned upon fighting and losing the oral battle. Her body acted according to her desires as she wrapped her legs around her daughter's lower back and held on tightly. All the while, her hands moved to hold her cheeks, keeping her child oh so close as she tried her damndest to increase the passion behind their erotic tongue dance rather than letting it be a hasty and slobbery mess. Not that she minded it all that much.

For a long while, their kissing and heavy moans were all the noises that filled the room. But eventually, Katsumi thought it was time to switch things up. As much as she didn't want to, she pried her lips away from the desperate mother's own, the two of them gasping for air as a thick strand of saliva came between them, ultimately breaking apart to fall over and into Mitsuki's gaping mouth. Like the dirty sub she was, Mitsuki gladly swallowed any drool that dripped into her waiting mouth, licking her lips before exhaling in content.

Katsumi bit her lip as she witnessed the nasty, but alluring display, her wet cunt quivering as it cranked up her arousal. "Shit, Mom. You really are a dirty slut, aren't you?" Katsumi smirked, meeting Mitsuki's dazed eyes as the woman panted like a bitch in heat, unable to give - or even think - any sort of verbal response. "It makes me wonder just what other depraved things you're willing to do for the sake of pleasure. But, I think experimenting can wait for the future. 'Cause right now..." She leaned forward to give her horny mother a light peck on the lips, one that Mitsuki happily returned. "I want to give this beauty right here a whirl~"

Suddenly, Mitsuki's eyes widened as she arched her back, moaning in surprise. Startled, she could feel something invade her pussy while something else attacked her clit. It all caught her when she least expected it, but she wasn't about to beg to stop. "F-Fuuuuck~!" Mitsuki squealed as she came from the sneaky assault, bits of her cum squirting onto whatever had defiled her sacred place.

"That's it.. Scream for me, Mama~ Show just how much you've been looking forward to having your daughter play with your slutty pussy!" Katsumi grinned almost wickedly, looking down to see her left hand using its middle and ring finger to enter her Mother's cunt, the digits going in down to their base while she placed her thumb on the throbbing nub over her slick entrance.

"B-Babyyy~!" Mitsuki panted, unable to rid herself of the lewd smile that cursed her flushed expression, her body wanting one thing and one thing only at that very moment.

"Mmm, good girl~ Don't fight back, and just go with the flow. Now, time for me to see just how crazy you can get up close." Katsumi chuckled, moving her fingers again as she pumped them into her older lookalike, starting off steadily as she twisted her hand in a drilling motion. With each turn of her hand, Mitsuki's pleasure was stacked upon whenever Katsumi's thumb brushed her clitoris.

"Ah, fuck! That... Th-That feels so... fucking good, Katsumi!" Mitsuki cried in acceptance, her hands coming over her head to grip the pillow.

"I bet it does. Glad to see you're really getting into it, Mama. Now, how 'bout we make this just a little bit better for the both of us.." With a starved gaze, Katsumi eyed Mitsuki's right vulnerable tit as she moved her head towards it, making the woman gasp upon latching her lips over the nip that remained unattended till now. She delicately kissed the pointed nub a few times before involving her tongue in the fun, getting it slick with her drool. Her fingers transitioned from literally drilling her mother's pussy to simply pumping into her, increasing the speed. Her thumb retreated as she used her palm to tend to the twitching clit, rubbing it whenever she drived her restless fingers into Mitsuki's dripping honey pot.

Mitsuki didn't know what her daughter's definition of 'a little bit' was, but it surely couldn't be this as every wonderful sensation that pulsed throughout her being rised in intensity, making her euphoric cries much more audible. 'I can't believe I'm letting my daughter do this to me... It's so wrong..! Sinful on so many damn levels..! But fuck, I love it~! Her fingers are hitting all the right spots, it's like she knows my pussy better than I do! Shit, how is she doing this~?!' Her pelvis started grinding on her daughter's dominant limb, moving with the teen's fingers.

'Now let's see how sensitive she is to this.' Katsumi thought mischievously. For the moment, she ceased her teat suckling to trap Mitsuki's nipple between her pearly whites, giving the erect nub a love bite.

Indeed sensitive, Mitsuki jolted whilst crying out joyously, the addition of pain with pleasure making her lustful insanity worse.

'Hit the jackpot with that one~' Katsumi smirked, resuming her eager sucking. "Mmm, Mama~" She moaned, pressing her face fully into Mitsuki's bosom as she gave her breast an especially hard suckle before releasing it with a wet POP! Of course, she wasn't finished as she shifted her attention over to Mitsuki's left breast, continuing her 'daughterly loving' there.

For who knows how long, Katsumi's mouth only continued to assault her poor mother's tits, doing so without remorse or mercy. Her fingers were unrelenting as well, losing track of the times that she had made Mitsuki's pussy squirt and squeeze on her digits. But, as with most good things, they must come to an end in order to make way for better things. And it can only get better from here.

Regaining control of herself, Katsumi ended her 'feeding' as she promptly released her mother's breast, licking her lips slowly as she then admired Mitsuki's shivering form. Speaking of Mitsuki, control was the farthest thing from her grasp as she could hardly gather her sanity, much less her thoughts as she remained ever so sexually elated, and exposed to her daughter. "Beautiful..." Katsumi whispered, gladly taking in the sexy sight. She looked down to her hand that was drenched in the older woman's glistening juices, a smirk coming to her as she rubbed her fingers together before bringing them to her mouth. As a taste test, she gave her middle finger a gentle lick. Instantly, she shakily gasped upon processing the deliciousness that was her fuckable mom, as just like that, she had a craving for more... and she'd get more. But, straight from the source this time.

"Guess it's time for me to really dig in." The busty teen spoke before lowering herself down to the dazed MILF's cunt, planting light kisses over Mitsuki's smooth belly along the way.

Still very much sensitive... well, everywhere, Mitsuki heatedly panted when feeling her child's kisses, biting her lip as even in her weak and vulnerable state, she knew what's to come. She wasn't about to protest, evident by how she brought her hands over Katsumi's head, moaning readily as she ran her fingers softly through the teen's spiky locks when she reached her waiting pussy. As for the rest of her body, she was ready for a tongue fucking to remember.

'She's so fucking wet..' Katsumi breathed heavily upon gazing at Mitsuki's dripping slit up close, her thumbs coming to the slick lowers lips to gently pull them apart, getting a deeper look into the woman's impatient vulva. 'And she's twitching so much down here too.. Ah, fuck it! I was gonna tease her a bit more, but even I can't wait to chow down on this fucking awesome pussy!' "Itadakimasu~" Not daring to keep herself waiting any longer, Katsumi commenced the feast right then and there.

Her eyes shooting wide open, Mitsuki emitted a euphoric cry when feeling her daughter ruthlessly invade her pussy so suddenly again, immediately writhing with intense pleasure as her mind and expression returned to a state of lustful stupidity. "O-Oh, fuuuhuckkk~!" The woman shrieked happily, grasping Katsumi's head as she didn't hesitate to grind her cunt on her child's face. With a dumb grin, she gazed down at the teen below for a moment, said teen lost in her own actions as her eyes were half-lid, looking beyond delighted to be tasting her mother's love juice right from its tasty wet source.

Pressing her tongue deep into her mother's snatch, Katsumi ravenously explored the squeezing vaginal cave, her lips making out with the spread folds outside all the while. To drive Mitsuki even more crazy, she wildly shook her head to brush her nose against the woman's clit, causing it to throb excitedly with each little 'punch'.

"F-Fuck, baby~! Y-You... You're s-so... amazing~! C-Cu... I'm gonna..! c-cum! I'm gonna cuuuuumm!" Mitsuki announced in a quivering daze, her eyes crossing as her body started locking up, feeling her next orgasm fast approaching. As her muscles tensed and spasmed, she clenched her thighs against her daughter's head, encouraging the teen to make her absolutely explode.

Throwing fuel at the fire burning within Mitsuki's loins, Katsumi raised her right hand beneath her chin to pump a couple fingers inside her mother's cunt. All the while, her wild wiggling tongue pulled out all the stops to make the woman cum, determined to unveil more of this shameless slut's true nature.

"C..! C-Cu..! CUMMMMIIIING!" At the top of her lungs, Mitsuki screamed out in utter bliss as this occuring climax rocked her world! Forcing her to cream uncontrollably on her young lookalike's face as she held it to her gushing pussy. Her senses turned to mush, Mitsuki's eyes rolled back into her skull as her screams then went silent. Her orgasm reaching its peak, her muscles began to loosen up, that delightful tension starting to slip away ever so slowly.

Finally, she let go with an audible groan, releasing Katsumi as her entire body went limp from the afterglow. A naughty grin was etched on her face as she twitched sporadically, her pussy still plenty dripping.

Regaining whatever senses she had left, Katsumi gulped down her mother's cum as she ascended to her knees. She licked her lips as she watched Mitsuki quake and quiver before her, far from getting tired of the sight as she flashed her 'happy' grin. "I knew she'd fall weak, but shit, this is some next level weakness." She scoffed, remaining silent as she allowed Mitsuki time to recuperate.

Eventually, Mitsuki recovered some sense of rationality, her mind slowly gathering itself as her breathing somewhat steadied. Then, as her vision cleared, she found herself staring at the ceiling, blinking as she briefly wondered where she was before remembering. She smiled weakly. Before she could truly comprehend their... activity, Katsumi popped into her sight when she moved to come over her again. Their breasts reunited as they pressed together once more, their faces coming close.

"K-Katsumi?" Mitsuki softly exclaimed, blushing profusely as they locked eyes.

"Hey, mama. Glad you're back~" Katsumi responded with a saucy smirk, leaning to give Mitsuki a chaste kiss. Surprisingly, Mitsuki didn't fight back, only going in shock for a moment before returning the favor.

Smack~

"Mmm~ Didn't even fight back despite having a clear head. Mama, you dirty girl~" Katsumi immediately teased after their kiss, giving her mother's nose a light boop as she chuckled.

Once again, Mitsuki's face went red, shyly looking away as the shame just now set in. But, only barely as she still rather enjoyed the new form of... family affection. "Sh-Shut up.. We've already crossed many lines that shouldn't have been crossed... So, it's a little late for me to start having regrets.. Especially when I actually..."

"Liked it?"

Mitsuki deeply breathed, not saying a word as she merely nodded at her daughter's assumption, finishing a statement she couldn't. As much as she wanted to, Mitsuki couldn't deny what felt good to her. And boy, did getting 'toyed' with by her daughter take her on a pleasure trip. It was almost on par with her and Izuku's love fest. Oof, so close. However, even if Katsumi really tried, Mitsuki was positive that nothing would've surpassed the pleasure that Izuku had so generously pounded into her hours prior.

Him... and that magnificent cock of his.

To her, nothing could possibly please her more than him and that delicious monster between his legs. The fleshy beast that had so aggressively asserted its dominance over her still sore and soaked pussy, and claimed it by marking her womb with his seed. Aiming her gaze at the wall beside her, Mitsuki bit her bottom lip as she reminisced about her sexual encounter with Izuku, wishing to repeat that magical time.

"What ya thinking about~?" Katsumi interrupted her mother's thoughts, cocking a brow as she witnessed Mitsuki lose herself to her imagination.

"Oh! U-Uh, nothing!" Flustered, Mitsuki shook her head back to its senses, steaming puffing from her cheeks.

"Hmm, if I didn't know any better... I'd say you were thinking of something very naughty. Were you perhaps... thinking of Deku?" Katsumi giggled, grinning as she's confident in that guess.

"M... Maybe.." Mitsuki pouted as she remained looking away, not about to be dishonest. Anyway, it's time they address the elephant in the room. "So... what happens now, Katsumi?" She asked, taking on a serious tone.

"Whatever do you mean, Mama?" Katsumi replied calmly.

"I mean, what do we do about our... Izuku situation?" Mitsuki managed to look to her daughter as she asked this, frowning as this next part wasn't going to be easy to speak... But, it needed to be said. "I know he's your boyfriend and all, but... Katsumi, I don't know if I can let him go. Not after the time we shared together. At this point, I've expressed the feelings I have towards him pretty clearly, and we sure as hell know that I wouldn't sleep with just anyone.. I don't want to fight you for him, nor do I want to break you two up, because I know he makes you happy. But I... I love him, too, Katsumi. I wish I could've kept that secret still, but I just can't anymore. Holding myself back is what led to all this to begin with. I saw an opportunity to show how much I love him... and I took it. It's fucked up that I went behind your back, I know. But, at the same time, I don't feel the slightest bit of regret now that I really think about it. I got to experience his love for me, and I'm so glad I did.. And as long as I'm being honest, I want to keep feeling it... and keep giving mine to him. For the rest of my damn life, if possible. Now, I ask again, what are we going to do about this?" Mitsuki concluded, that whole speech putting her through a whole rollercoaster of emotions as she was both teary-eyed and stern looking, happy at finally letting her feelings out, but also fearful of the potential tension they'd cause. Even so, she refused to back down.

"Mom..." Katsumi quietly called, looking blank for a good minute before displaying a sincere smile. "You're an idiot." She softly chuckled, shaking her head as she didn't look the least bit bothered.

Mitsuki blinked at the teen's reaction, not at all what she expected to get. Allow Katsumi to explain herself.

"If I really had an issue with you taking your shot at Deku. Trust me, we wouldn't be laying here together like this.." She made her point known by pressing her naked body tighter against her mother's, the woman softly gasping as their nipples rubbed harder together. "I especially wouldn't have gone through all the trouble of... evolving our bond as mother and daughter." She devilishly giggled, riling Mitsuki up a tad more by giving her nose a quick lick. "No, no, no. Instead of all this, you'd be fucking dead to me as a mother could be. But, let's not get into that. No point in it really. Now, would you believe me if I said that for a long while... I wanted to share him with you?"

Caught very much off guard, Mitsuki was utterly stunned by the question, blinking even more out of shock as that took her a minute to process. "Y... You did..?"

"Mhm! Seems to be our only option as far as I can tell." Katsumi nodded, her serene smile still present as she sighed. "I may not show it as much as I should, mom, but I do really love you, and I do want you to be happy, just as I am. Sure, a lot of the time we get on each other's nerves over the dumbest shit. But, that never meant I didn't want happiness for you. Us screaming our asses off at each other... That's just us being the hot-tempered bitches we both know we are. We're Bakugo women, after all." She lightheardedly scoffed. "Anyway, I knew about your feelings for Deku long before today, and vice-versa. So it wasn't a shock that you two ended up banging. You're not as slick or subtle as you think you are, mom. Plus, you know, I'm not an idiot. I've seen the way you look at him whenever he's around. I swear I could see hearts in your eyes whenever you're eyeing him up. You've also been smiling a lot more. Shit, your smiles are especially bright whenever you two are engaged in conversation. Whenever his attention... is on you. And don't think I didn't notice the way you started dressing either. Before him, never have I seen you wear so much low cut tops and tight ass leggings to show off that juicy booty of yours. I mean, honestly, that was by far the deadest giveaway for me." Once more, she stifled. "Now, what you're probably wondering is, why didn't I say anything sooner? And my answer to that is... well, how the hell does a teenage girl go about telling her mom it's okay to fuck her boyfriend without freaking either of them out?" She said with a chuckle. "So, to avoid the awkwardness of trying to force it, I said fuck that! And decided to patiently wait until it happened naturally. Lo and behold, it finally did. Thank fuck for that, because I was beginning to run out of patience. If I had to wait even a few months longer, I'd have just thrown you two in a room one day and urged you to get it on right then and there. Thankfully, it didn't come to that. Yay us, right?" She shrugged, still pretty nonchalant after everything she said. "So, what'll it be, mama? I'm all game for polygamy if you are. Like you said, we've crossed many lines already, why not another? There's no going back for us at this point. You know that, I know that. So why not embrace the wild side and explore it more~? Who knows; Maybe it'll be fun. You got to experience what it's liked to get fucked by us individually. Now just imagine how it'll feel when you... mesh the experiences together.." Quirking her brows suggestively, that sly grin of her's returned, slowly bringing her hands over to her mother's own to lovingly embrace them, their fingers interlocking as their palms came together. Their noses lightly touched, their lips following suit as they were so very close. "Gets me fucking wet just thinking about it~" Katsumi licked her lips, resisting the temptation to claim Mitsuki's own as she wanted to hear her final answer.

Speaking of her answer, it didn't take much thinking before Mitsuki made the ultimate choice after processing all that her daughter had said. God, had she really been that obvious this whole time? Indeed, she thought she'd been slick this entire time. And obviously, she was wrong to think so. Well, at least it's all out of the bag now and she isn't getting berated because of it. So, that's a win.

Other than the... well, incest part of the deal, there wasn't much holding the woman back from accepting Katsumi's proposal. She denied herself the chance to love for too long, and wasn't at all tempted to prolong that torment. She wasn't lying when she said she didn't want to break the teens up. She loved her daugher, she loved Izuku. And she knew that they made each other happy. She couldn't bring herself to destroy that even if she wanted to. Instead, she just... wanted in on it all. She had a taste of just one of the ways Izuku can express his love, and like an addictive drug, she wanted more. So much more. No, she didn't just want sex. She wanted the WHOLE nine yards. She wanted to be respected by him, held by him, cared by him, kissed by him. All in all... she just wanted a life with him. Chances are that she's already carrying his first child. One of many she hoped. So the fantasy was all the more alluring. If sharing Izuku is what it'd take to achieve her dream, she'd be a fucking fool to refuse. Hell, it's what she wanted anyway.

Her actions speaking louder than words, Mitsuki gave her answer by initiating the kiss, her hands squeezing Katsumi's own as she moaned in acceptance to their liplock. If she's to share a man with anyone, it'd be this girl right here. And she's grateful that Katsumi felt the same about her.

"Oh, Mama~" Katsumi moaned in elation, breathing heavily as she returned the kiss with more excitement, their bodies grinding in unison.

With their united fate decided, Katsumi, with all reluctance, ended their kiss before the spice can get hotter, the duo panting when their lips disconnected.

"Wh-What are you doing..?" Mitsuki asked with an adorable pout, wanting more of her child's love.

Katsumi grinned at her mother's desperate tone, pleased that she had her wrapped around her finger as much as Izuku did. "Aww~ Don't worry, Mama. You'll get your pleasure." She chuckled. "I just thought it'd be better if you received it from him."

Mitsuki smiled brightly as she immediately knew who him was. "Izuku? He's still here?"

"Yup, and he's all for having us both as his lovers." Katsumi replied. "So, how 'bout it, Mom? Do you want to go and get... daddy's love?"

'D-Daddy?' Stunned by the bold nickname for Izuku, Mitsuki's face went red as her whole expression went bashful. And for good reason. 'Why... does that sound so fucking hot?' The woman thought as just imagining herself calling Izuku daddy had her loins burning with lust. Especially when imagining just how good he'd fuck her when she screamed it to him. 'Oh, fuck, let's do this!' Eager to receive their daddy's love, Mitsuki nodded impatiently, wanting to see their lover so very much. "Please.." She pleaded.

Katsumi's grin got wider. "Let's get going then." Not saying much else, the teen prompty dismounted her mother before walking over to her bedroom door, her hips moving with a sexy sway as her ass cheeks lightly bounced with each step. Before stepping out, she glanced over her shoulder at Mitsuki, cocking her head outside the room with a smirk. "Come on, don't wanna keep him waiting much longer, now do we?" She winked, stepping out to head to Mitsuki's room. The master bedroom.

Needless to say, Mitsuki didn't need much encouragement as she instantly shot out of Katsumi's bed. Dead set on reuniting... with their beloved.


A/N: Alright! Time to finish this bitch! XD
