Aphrodisiac

A Senran Kagura fic commissioned by Dysentia

You are a very lucky man.

When Yumi brought home some old Shinobi incense for meditation purposes, you thought nothing of it. After all, your ninja girlfriends are always working with this and that in their study of ninjutsu and other arts. It’s all above your head, you’re just the dutiful boyfriend who makes sure they have a very welcoming home to return to. That incense can be anything other than just a different scent is all new to you, but you trust that they wouldn’t bring anything too strange or risky into your home. And when you have two girlfriends, particularly a pair as gorgeous as Yozakura and Yumi, you don’t really expect anything could possibly make your life even more amazing, so you don’t expect anything out of the ordinary. Really, it was just going to be you and your girlfriends leaning back, enjoying the pleasant scent of the incense, and letting it focus your meditation.

And that was how it started. Yozarkura respectfully lit the incense and you let the smoke curl its way upward, a spicy, unfamiliar scent filling your nose as you closed your eyes and allowed yourself to enter a state of meditative bliss… but since you weren’t a trained and disciplined Shinobi like your girlfriends, your mind didn’t exactly drift to a higher state of consciousness. You were never much for meditation or contemplation, no more than you were other Shinobi concerns, but you participated in it because you liked doing things with your girlfriends. But that meant, while you were supposed to let your mind transcend to a higher state, it was instead heading to a… much, much lower one. Especially as the incense made you feel really… really good, the earthy scent making you feel very… energetic down there.

As you feel your cock start to harden, your mind clears to a very pleasant vision of Yumi and Yozakura… your sexy Shinobi, perhaps finding themselves in a similar state under the incense. Unable to reach meditative transcendence, but instead finding it harder and harder to escape their bodily desires. You can practically hear them fidget as your imagination paints a lovely picture of the both of them, their cheeks growing flush, their breathing becoming heavy as they, like you, find themselves unable to escape the lure of thinking with one’s genitals. Thoughts of what you could be doing instead of meditating catching your disciplined Shinobi as easily as it normally catches you, seeing them brought low by their baser desires.

It’s a bit childish of you, you certainly don’t begrudge Yumi and Yozakura for their superior ability to go ten seconds without thinking about sex, but really, with those two for your girlfriend, it’s unfair to expect you to stay so high minded! Really, it’s only fair that you get to fantasize about evening the score. And your mind happily agrees, picturing Yozakura undressing Yumi, attending to her leader’s needs, her fingers delicately slipping into her yukata to explore her-

Wait.

That’s not your… maybe the moans and gasps of arousal are your imagination, but there is no chance you can imagine a hand stroking your cock so vividly!

Your eyes shoot open, needing to get a sense of what is going on as you realize that… that your fantasy, awakened by the incense, might have more truth to it than you might have thought. Yozakura’s fingers are stroking your dick through your pants as she, her eyes tightly closed, moans with lascivious need. Yumi’s no better, leaning back with her chest thrust forward, her hips unconsciously rolling as she-

Wait, wait-

WAIT.

With her back arched, you can see Yumi’s chest, barely even constrained in her loose white dress, visibly expand. She was already an impressively busty woman, but as she raises a hand to paw at her own tits, her swelling chest proves to be too much to be constrained by her loose top as her boobs simply spill out! Yozakura’s fingers stroke you even harder, reminding you that both your girlfriends are under- are under the effects of whatever this incense is doing, it’s smoky haze now filling the room, and her tits are also expanding, her bust likewise spilling out from her clothes as she makes a low, lusty sound.

You’re not exactly objecting to the show, but when weird stuff happens, you can’t not try to figure out what’s going on! “Y-Yozakura,” you gasp, making her eyes flutter open in dull recognition, “Yumi! What’s- your- how- I- I- TITS!”

Articulate as always. But it has the desired effect of rallying both Shinobi to consciousness as their eyes open and they realize that it’s not just fantasy but reality that their tits have swollen to truly titanic proportions and that the three of you are feeling a lot more than your usual randiness. They blink. You’re suddenly not sure what a Shinobi could even do about magical incense gone wrong, but then…

Yumi looks at you with a heavy-lidded gaze as she raises up her hands to cup and squeeze her naked tits in a lewd display. “Mmmmm, I don’t know how the incense did this, but- OH!”

She suddenly gasps as, while giving her nipple a teasing pinch, a sudden squirt of white milk sprays out, startling all three of you.

But only for a moment before Yozakura begins tugging at her own nipples, and what started as an accidentally discovery soon becomes an eager, giddy milking as both girls explore the volume contained within their newly filled jugs, only to discover that there was a seemingly boundless flow of milk squirting and dribbling from their nipples. It was evidently quite a pleasant sensation from the looks on their faces as your girlfriends become a milky mess, puddles of white now forming on the floor.

And it’s definitely a pleasant sensation for you. Whether the incense has any effect on men, you’re not sure, but you certainly are getting hard at the sight of two sexy Shinobi giggling and gasping as they fondle and milk themselves. Painfully hard, and while you’re still a little concerned about whatever other side effects might exist from such a magical transformation… the much, much louder voice in your mind is concerned with a far more pressing concern.

“Umm… Yumi?” you ask, trying to still show some courtesy rather than just jump right to ripping your pants off and getting to the fun stuff, “Are you- are you okay?”

“Ohhhhhhh,” Yozakura responds instead, shivering with pleasure as she tightly squeezes her tits, milk leaking from between her fingers, “I feel wonderful...”

But there’s a part of you that still can’t accept that this is happening, that your life could possibly get more amazing without some sort of sinister catch. “But what...” you murmur, trying to come up with an objection as you watch Yozakura’s hands slip on her slippery, milk-soaked tits, “But what about, um...”

“I- I don’t… I don’t care!” Yumi suddenly declares with a giggle, “I I have- I have boobies now! Adorable, cute, girly, bouncy boobies! And they feel so amazing! A- and…” her lips curl into a wild grin, “I know what’ll make them feel even better… Yozakura!” she barks, quickly commanding her enforcer to follow her lead, “Let’s show our boyfriend how amazing we can make him feel!”

She’s upon you in an instant. Which shouldn’t surprise you: again, your girlfriends are ninjas, but with your current state already foggy from arousal, it’s like Yozakura simply teleported onto you. She’s always been the more direct of the pair, even as Yumi’s subordinate. But you’re also used to seeing her have a more ladylike disposition, which is not how you’d describe the way she dove upon your legs, reduced your pants to tatters of fabric, and wrapped her big, milky tits around your newly-freed cock.

But it’s not like you’re complaining, of course.

You can barely control yourself, your awareness of any part of your body beyond your cock is almost nil as the sensation of big, pillowy tits wrapped so tightly around your shaft drives any other awareness out of your mind. You’ve had titfucks before—your girls are insatiable, after all—but nothing like this, with Yozakura’s vastly expanded bosom meeting your dick in a heavenly embrace. As you moan from the sensation of the magical up and down hell Yozakura is putting you through, you’re suddenly assaulted by a whole new sensation as Yumi swoops in to join her. Your eyes go wide as your dick is simply drowned in soft titflesh, its head bobbing in an ocean of boobs, like a ship on stormy waters.

“Mmmm, you’re- oh, you’re...” Yumi moans as she squeezes her tits around your shaft, “you’re so much more than a boyfriend, be- because, oh fuck, because I wanna- I wanna- B-because I’m my- my- ” suddenly, she cannot contain herself any longer as she throws her head back her head and squeals, “M-MY HUBBY’S GOOD LITTLE WIFEY!”

She seems to explode just from saying it, as though those words had been bottled up inside her for so long that the pressure of keeping it in had become unbearable. She keeps up her tittyfuck with devoted intensity as she looks at you, a manic gleam in her eye and a wide grin on her face, and pronounces, “That’s- ha, yes, that’s it! I don’t- no longer- I wanna be your wife! Your sweet, doting little wife! Who takes care of all her hubby’s needs! C-cooking, cleaning, and cock, that’s what I do!”

A mad giggle accompanies her proclamation, but it doesn’t sound deranged. Rather, there’s an inescapable… sweetness to it, the unrestrained giddiness of a woman who’s finally had the chance to embrace being the woman she’s always wanted to be. You’ve known about Yumi’s insecurities about being “cute” enough to ever satisfy a man, even as you’ve always assured her (and definitely meant it) she’s more than enough just as she is to keep you happy. Maybe it’s her magically enhanced bust, maybe it’s just a sudden burst of confidence, but all you’re really focused on is that it is hot as fuck to hear a sexy Shinobi declare her devotion to your dick. You really can’t help yourself as your cock twitches and jerks, ejaculation imminent as Yumi dives forward, swiftly taking your shaft to the hilt as you release, pumping shot after shot of your seed directly down her gullet.

You’ve never cum so hard before in your life, just an absolute, ball-draining firehose of your seed that Yumi’s all too happy to guzzle down. It… it takes something out of you to go through that. A magically-enhanced double titfuck culminating in your girlfriend proudly revealing her housewife fantasy before sucking you dry is a lot to happen in a day. And yet, you realize you’re certainly not done.

Because you’ve also realized… while Yumi’s been ecstatic to share her newly admitted, though clearly long-held, desires to you, Yozakura has been silent for a while. A look at her face shows she’s slowly processing something through her mind as she watches Yumi messily swallow your load, licking her lips to be sure she got every last drop of your cum. But unlike Yumi’s naked enthusiasm, she seems far more… contemplative. As though she’s been rocked by some great realization.

“Yozakura?” you ask, seeing the dazed, distracted look on her face, “Do you… do you also have something to-”

“Need...” she murmurs, her voice more of a low, base rumble of unconscious desire, “Need… need to be…” her eyes flash with something primal and urgent as she finishes, “Need to be bred. Breed me… BREED MEEEEEEE!”

Her mind is too scrambled to articulate her feelings in more than just a plaintive shriek, but once you’ve heard it, you can’t deny her request. Her voice is full of mad desire, and though you’re under the influence of magical incense… you very much get the sense that, just like Yumi, Yozakura’s speaking from a place of buried truth. Rising up, you feel your dick spring back to its full strength. Almost certainly the effects of magic, but seeing Yozakura drool at the sight of your dick, pinching her nipple with one finger to let out a spurt of white milk as the other spreads her dripping pussy lips to show her undisguised need, you feel it might just be how fucking sexy she is.

“Breed her,” Yumi sighs in pleasure, “Pin your slut to the floor and fill her with your seed...”

Her endorsement reassures you that both your girlfriends are more than onboard as you approach her, your cock, rock hard and proud, bobbing like a conductor’s baton as you get ready to guide Yozakura into a whole new kind of relationship. Her manic need has subsided as your cock gets closer to her needy cunt, where had once been wild squeals of desire were now trembling mewls as she anticipated your penetration of her. Rubbing your cockhead against her dripping slit, it practically pulls you in, and yet, you delay a moment longer, smiling down on Yozakura as you tease her. She whimpers, delirious with her need to get her pussy stuffed as she opens her mouth-

Just in time for you to slam into her.

Yozakura’s eyes go wide. Her mouth, already opened, is unable to do anything but gape, soundlessly, in surprise as the sensation of your dick, balls deep within her pussy, proves to be simply too much for her to handle. But she pays you back—her pussy grips your cock like a vise, and while the rest of her body’s too blown away to make a move, the walls of her pussy do not hesitate to start milking you for a load of your seed.

With a groan, you begin to thrust away, in and out, in and out, and it’s difficult to control yourself as Yozakura slowly regains her self control. Her words come back, first in the form of a wild giggle, and then she returns to begging, pleading for you to breed her. Her hips buck in time as yours do, desperate to take you deeper as her pussy makes use of every skill a Shinobi knows of seduction. Suddenly, her arms shoot up to loop around your neck to smush your face into her overflowing tits, popping a fat nipple into your mouth. Instinct takes over, a long-lost memory from your own infancy that remembers what to do in this situation as you take a deep, long suck as you fill your cheeks with warm, sweet milk. Gulping it down, Yozakura swiftly fills your mouth with more as you suckle away.

Reluctantly, you pop your lips off her tit, milk dribbling down your chin as you resolve to take charge of the situation once more. Looping her legs over your shoulders, you put Yozakura in a mating press as you start pounding her, sending her into a wild set of shrieks and squeals, the closest thing to coherent words in the delirious noises that sound like “Fuck!” and “Breed!” in between her gasping cries.

“A good wife would help her husband knock up his slut!” Yumi giggles from behind you as you feel her lips brush against your balls. As you slam away into Yozakura’s pussy, your sweet little wifey is helping you fill her with your seed by lavishing your balls and shaft with kisses and long, lascivious licks. It’s an incredible sensation, and you’ve never had anything like this! The three of you have had plenty of threesomes, but you’ve never heard Yozakura beg you breed her while Yumi fell into the role of your devoted wife-slut. And maybe it’s the effects of the incense, but…

Fuck if it isn’t an amazing experience!

You can’t control yourself any longer. It was folly to think you could delay it at all, and a damn sight impressive that, with all this, you’ve been able to keep from cumming as long as you have. With a mighty groan, you pull your dick back, feeling your head scrape it’s way down the full length of her pussy, nearly to her lips… and then you slam in, releasing as you bottom out in her, emptying your balls directly into her womb. Yozakura shrieks her climax, throwing her head back in a howl of satisfaction as she feels your warm, sticky cum fill her up. You even hear Yumi sigh in pleasure, a self-satisfied noise as she dutifully tends to your balls, content with the knowledge that she’d been a good wife.

Withdrawing from Yozakura’s pussy, Yumi’s all too quick to latch her mouth to your dick, noisily slurping up any mess until you’ve been licked clean. You glance over to where Yozakura lies in an utter daze, a mindlessly happy grin plastered to her face as your seed leaks out of her overstuffed pussy. This feels… this feels pretty goddamned incredible, and even though you feel like a year of your life has just been sucked from your body, it feels like a worthwhile trade. Another glance over to where the stick of incense has now burned down to its base, you wonder if you should ask the girls about getting some more… that is, if you think you could survive it.

Yumi, finished with cleaning your cock, guides you to lie down on the yoga mat, to get yourself comfortable. And, of course, she proffers a milky tit towards you, saying, “You know, it’d be… very irresponsible of us if we left you dehydrated...” But you can see on her face that she’s more jealous that Yozakura got to experience you sucking on her nipples and she doesn’t want to be left out.

She sighs in pleasure as you begin sucking away, drinking your fill of her milk. It is quite refreshing, though the three of you seem too tired to really do much more. Yumi guides you to rest your head in her lap as you let contentment wash over you, the last traces of the aphrodisiac leaving your system as you let the embrace of your loving girlfriend, and the happy, contented sighs of the other, take you to sleep.
