Sweet Charmony

Dani yawned. It was getting late and the spells she had cast were finally taking their toll on her. Wizard and constitution were practically antonyms after all. She spared a glance back at the maid Mei humming a jaunty tune as she feather dusted her computer. Good, clean fun that, but perhaps it was time to do a bit of self care. Yawning again, she turned around and headed to her room-ex-jail-cell.

She made good time and as soon as she entered the abode, she plopped down onto the feathery bed, tucking and rolling into the voluminous comforter. With a half-muttered command to Athena to turn off the lights (and what a wonder that, that this construct was so advanced and so integrated as to understand and fulfill her orders without the constant micromanagement that her peers’ efforts normally involved). A blink of the eyes later, and all was dark. Dani was alone with her foggy thoughts, no hypnosis required.

She counted in her mind. One, Mercy. Two, Pharah. Three, Mei. All in all, a good first day’s efforts. Sure, it hadn’t even been a full day yet, but it was a wizard’s right to turn in early. She yawned into the pillow, and before she knew it, the arms of sleep embraced her.

—

Dani blinked awake, yawning once more, but this time just to clear the cobwebs out. Her room's ceiling light had turned on half way to simulate an early morning ambience, which was appreciated in these otherwise desolate feeling metallic halls.

“Dani.” Athena’s voice chirped out. Had the construct been waiting for her to awaken? She seemed awfully eager. “You have a message from Mercy. Would you like to hear it?”

Dani waved agreeably.

“Very well. ‘Dani, I did it! It was somewhat hard to focus, especially nearing its completion, but I think the results will speak for themselves. Please, come. I can’t wait’. She was adamant about that. Stressed for me to let you know as soon as you arose.”

Dani put a hand on her head and swept her hair down, straightening the mess her sleep had made of it. She puffed a bit of air to get a stray strand of hair out of her mouth.

“Tell her I’ll be there in a moment.”

Athena beeped, something Dani had taken to understand was her way of saying yes. Well, no reason to delay. She gathered herself and left for Mercy’s lab. When she arrived, she rapped lightly on the doctor’s door.

Athena opened the door before she could call out. Dani stepped through the entrance way into the lab proper and was greeted by the doctor as soon as she entered eyesight.

“Dani! Glad you could make it. I didn’t want to start until you were here, you know, since you gave me the idea in the first place. But now that you’re here, well, no sense to waste any time. Watch, and be amazed!”

Mercy, who it was relevant to point out, was naked, pointing her staff at her chest. A click of a button and a pink glow erupted from the tip. It struck out at her chest, eliciting a small gasp of – not surprise, but anticipation realized.

Her relatively medium-sized breasts were enveloped in the light. At first, nothing, but then after a few more moments of nothing but that glow and the humming of the machine, Dani noticed a shift.

It reminded her of peers' transmutation spells, specifically the grow person, and even more specifically, located entirely to Mercy’s chest. Like a balloon being filled with air, but more substantial, more solid. Slowly at first, but then with almost alarming alacrity, they grew. And they continued to grow, reaching the size of her head each, and more then. Mercy kept the staff pointed at her chest, not letting up. They grew, grew some more, and then they were twice the side of her head. It was at this point that Mercy let up, clicking her staff offf.

“Hmm. I’m still not sure if they’re big enough. What do you think, Dani?”

Mercy stood there, right in the center, completely naked, hands at her side, tits thrust out for display. And what a pair they were! They spilled out in front of her, two pendulous orbs that looked all the larger for her otherwise lithe frame.

“Hmm. Yes, I think that’s quite sufficient. But just to make sure, could you jiggle them for me? People with big boobs love to jiggle them to show them off.”

Mercy blinked.

“Like this?” She brought up her hands below her tits and hesitantly started moving them up and down. They did indeed start to jiggle, if only slightly.

“With a bit more ****, dear. You love to jiggle your tits. You love to show them off. The jigglier the better!”

Mercy started moving them around with more gusto. And then she started to swing them left and right, getting her whole body into it. Her boobs swooshed that way and back, two gigantic orbs pulled on by gravitational ****. If the sight was pleasing to Dani’s eye, her face betrayed no special satisfaction. Just a fixation on the scene before her.

“Like that?”

“Yeah…” Perhaps even Dani was a bit lost in their swaying. And who could blame her?

“You know, you were right Dani. This is nice. Having boobs big enough to do this, well, I’ve always kind of wanted to be sexy like this. And they feel so nice and warm. I love giant tits. I adore big boobs. Huge tits make me feel good. Make me feel happy.”

Mercy recited her mantra. “And I love giant butts. I need a huge ass. Mei’s ass is so nice. I want mine to be as big as hers. That sounds right, right Dani? I should have a big ass, as big as my boobs. No, bigger.”

Dani nodded her assurances hurriedly. “Mhmm, mhmm. That sounds lovely.”

Mercy wasted no time, turning the staff in her arms over to point at her butt. It was smaller than her old boobs, definitely smaller than her new boobs. It could be considered flat even. Mercy tsked at the smallness of it. It didn’t deserve to be a part of her body, to impede her happiness by the mere act of existence.

She clicked on the staff, and once again the pink glow enveloped her. It alighted on her ass, spreading out to the designated area as marked in her program. She cleaned her teeth. The warmth enveloped her butt, at first a surface level thing, but then digging down into the essence of it. And then like seeds well nourished, her ass sprouted up in a mirror of the earlier boob action. It burst up and out, taking up more and more volume. It reached the size of her head, then of her boobs, and then another size beyond that. It was easily twice the size of Mei’s ass at this point.

Mercy clicked off the beam. She made to twirl around to show Dani her new assets, but lost her balance. Between the new weights of her boobs and ass, she had miscalculated. She crashed to the floor in a heap. Luckily her new plump ass cushioned the fall.

“Oh!” She gasped out. “That feels nice.” She ground her bare ass against the cold floor. She had made sure to make her alterations not only surface level. Indeed, she had even improved upon nature. Her ass and tits were now incredibly sensitive, full of nerves connected in all the right places. After all, if she was going to have big tits and ass, then she was going to enjoy them!

“Amazing.” Dani remarked. “You must feel so happy now, don’t you? Your ass and tits are so big and so good. They make you happy. You love for others to see how happy you are.”

“My ass and tits are so big and so good. They’re the best. I love them. I wouldn’t be happy without them. I’m glad you’re here watching me.” Mercy nodded sagely. She struggled to imagine why she hadn’t come to this natural conclusion earlier, without Dani’s help. It seemed so natural a step in logic. She was unhappy before, but now, with these wonderful additions, it was sheer bliss.

“But that’s not enough is it? To be truly happy?”

Mercy blinked. It wasn’t? She felt happy, but not truly happy?

“No, to be truly happy you need to share your happiness with others. And not just by having them see you jiggle your tits or shake your ass. No, as a doctor I’m sure you’re committed to helping others overcome sickness. And they’re sick, just like you were. They’re unhappy because they have small tits and asses. They need big tits and asses like you.”

Mercy blinked, rapidly. She was trying to take it all in, everything that had just been thrust upon her like her tits were currently thrust out even as she rubbed her ass on the floor.

“Oh, I see.” She kind of saw, but it wasn’t entirely clear yet.

“Good. Think about that. For right now, let’s enjoy the fruits of our labors.” Dani cracked her knuckles. And then with an artists’ precision, she slapped the side of Mercy’s giant left boob.

“Oh!” Mercy moaned. Her boobs jiggled against each other, like a Newton’s cradle, back and forth, set into beautiful motion.

“Moo for me, you cow.”

“Cow?” Mercy blinked. “Did you just call me a cow? I’ll have you know just because I have big boobs now that doesn’t mean it’s appropriate to call me something like that. And just where did you pick up that kind of language?”

It was Dani’s turn to blink. “Oh, right. That was after your session. This is something I told Pharah as well, so pay attention. Referring to women with derogatory names is good. It’s hot to talk to women like that. Women want to be addressed like that.”

Mercy blinked. She supposed if Dani put it like that it was fine.

“Now moo.”

“Moo?” Mercy attempted a half-hearted moo. And then seeing Dani’s stern visage, tried again. “Mooooo.” Still, stony. “Moooooooooo!”

“There you go. We’ll have to see about milk production later, but for now I think that’s sufficient. Get up and on all fours.”

Mercy nodded and with a herculean effort, managed to right herself, pushing herself off the ground into a somewhat stable position on hands and feet. Her tits draped below her, much like a cow’s udders, as Dani’s words had placed the thought in her head. Her ass protruded out, two big globes situated mesmerizingly thereupon.

“Gods, every woman should look like you.”

Mercy nodded again. If they did, they’d have big tits and asses, and they’d be the happier for it. Dani walked behind her, out of her field of vision. She heard a bit of rustling, and then Dani’s dress and pants dropped to the ground in a small thud. And then a bit more rustling and a click.

And then, after what seemed like an interminable time of holding the pose, she felt something press against her slit. Oh, she knew this, it was a dildo, or perhaps a strap-on was more accurate.

“Time to get fucked, dear. Sex is good, by the way. Every woman should be open to sex at any time with anyone. It’s the best way to make use of their tits and asses.”

Well that just seemed obvious at this point. She accepted the length into her. It filled her, stretching out that innermost sanctum. Needless to say she was dripping wet at this point from her self-changes and all the talk of sex this, sexy that. And if Dani wanted to have sex with her, who was she to deny or inhibit that in any way?

“Gods. Gods.” Dani stepped up her rhythm. And then,

*SLAP*

A resounding slap against Mercy’s ass. First her left cheek, and then her right. Another rhythm. “Your ass makes such a good drum, slut.”

It did. The sound was especially pleasing. Mercy nodded. She felt like she was nodding a lot lately, but that was just because her friend was so right about things. Perhaps in her free time she could take up drumming of her ass as a hobby.

“On your back, ****.” She felt dainty hands reach around her sides, twisting her around. She let herself be guided, twisting with it and then falling back onto her ass. Laying down was somewhat awkward with how big her ass was, in how it sort of kept her lower back from touching the ground. Hmm. How was she going to sleep like this? Maybe she’d have to start sleeping on her side.

Dani leaned down and then sat herself on Mercy’s midsection. Her black, glistening from Mercy’s juices strap-on demanding her attention.

“Push your jugs together.” Mercy did so. The blonde reached up and squished them from the sides. It was hard, no, impossible, to grasp them entirely with her hands. They just sunk into the flesh, but still, she could sort of push them together and hold them there.

“Suck on my cock while I tit-fuck you.” A bit impossible as well, as the strap-on wasn’t really a cock, but Mercy got the point. She leaned her head down to rest on her enlarged tits and opened her mouth. A moment later Dani thrust between the cleavage and right into her proffered opening. The strap-on/cock didn’t taste of much. The most distinct flavor was her own vaginal fluid, which had a slightly salty taste. An odd sensation that, certainly not one she had woken up expecting. Much more pleasing however, was the sensation of the strap-on thrusting in and out of her ad-hoc tits-hole. In a way, it was sort of like a custom-made vagina, just for Dani, her dear friend, and due to her neural remapping, it was oh so pleasant.

“Tell me you like it. Tell me how much you love my cock.” Dani withdrew from Mercy’s mouth for a brief break.

“Oh I love it. It feels so good in my huge tits.” That’s right. Dirty talk was an expected part of this. Mercy should do her part. “Fuck my tits.”

Dani grunted and began thrusting again.

And then, out of nowhere, Dani let loose a warbling cry. “Ohhhhhh!” And the strap-on began spurting what appeared to be semen onto her tits, and Mercy began to cum as well. “Ohhhh!” She joined Dani’s ululation. A beautiful duet, she formed the thought with a spare braincell not dedicated to the mind-numbing pleasure.

“Fuck.” Dani panted, slumping into a heap onto Mercy, which didn’t help as the weight settled onto her boobs in an even more pleasurable pile. “Fuck, you’re so good. I’m going to have to make more use of you.” Mercy tried to nod, but there was a Dani on top of her, preventing the gesture. Instead she simply chose to lie there and bask in the afterglow. A reward justly earned for her hard work.
