A/N: Hey everyone, sorry for the sort-of hiatus. School's getting busier, games are coming out...time is hard to find for this hobby of mine. But fear not! With the help of my amazing girlfriend, I've been learning quite a bit stuff to help my writing! Anyway, please feel free to comment, review, message, etc if you want me to write even better!

"M-mmh..hyah...hah...C-Compa...hyaahh..!~" Neptune looked down to Compa, lewdly and hungrily sucking on her cock. She had woken up to the toe-curling pleasure a minute ago, still half-asleep but very much enjoying the volunteer wake-up call. "Compa...Compa..!~ hiyy!~ hyah..hah...I..I can't hold on anymore..!~ Hyaahh!~" "Mmhh!?~ mmmh...*gulp* *gulp*..mmhh!~" Compa struggles to drink Neptune's sudden torrent of semen, a good deal of it dripping down the shaft. "Mhm...hah..hah..geez, Nep-Nep...you shot so much..." She licks up what she missed as Neptune pants heavily, mind cleared and refreshed.

And with that clearing of her mind, she noticed something very odd. Checking her status screen, there was a new bar, or gauge, separate from HP and SP. It simply had 'XXX' in front, the bar showing about 80%...and it gradually dropped down to 70%. "Nep-Nep, are you alright? You look like you're thinking...you should leave that to Iffy." "Ahhh! I'm the main character, I'm allowed to think!" Neptune turns and sees her phone flashing with a message from Noire. "Hrmm..? She wants to talk to me about something important..? Daawww, lonely Noire finally wants my lovely company!" "Oh, Nep-Nep...you shouldn't tease Noire so much, even if it is true. I'll hold the fort here, so go and make her less lonely~" "Got it! Oh, and thanks for, uh...y-you know..doing these things for me..~" Neptune blushes, then gives a little kiss to Compa's cheek before scurrying out. "Anytime, Nep-Nep!~"

Meanwhile...

"Hah...mmh..hah...hah..hyah..!~ S-so good..so much is...shooting out...hah...should...keep it down...for a while.." Noire stood over her toilet, amazed at how much white cum her new asset produced, though she then quickly shakes her head and walks out, fixing her clothes and feeling relieved that her member softened. She checks the gauge in her status: 70%. "It only went down by that much..? Please, get here soon, Nep...!" She hoped to gain new info, and help, from her fellow goddess, though mostly because she was the only one besides her sister that she felt she could confide in.

"I suppose I should check the net too.." She mumbles to herself, sitting in a chair with her laptop. She attempts to search a few things, but after a few minutes, she slams the laptop shut, face flushed red. "W-w-why are there such lewd things online..!? Nep, please hurry..!"

Neptune finally arrives at Lastation's large Basilicom. It had finally become a nice place to visit after Avenir was kicked out for good. The high-rise building was huge, numbering over 50 floors, and Noire used the entire top floor as her home. What she found funny though was that, when leaving the elevator, it's as if walking through the threshold of an actual house's front door. The only way to tell otherwise was with the windows. You usually can't see the entire city through a regular window.

Walking in, she leaves her shoes at the entrance, then notices three other pairs. She knew two were probably Noire's and Uni's, but the last she recognized as Nepgear's, her little sister. "She must be hanging out with Uni..."

Walking along the hallways, she spots Uni's room and decides to take a peek. She walks in and sees both Nepgear and Uni sitting in front of a large television playing a racing game.

"Mmh? Just a minute, Onee-chan, we'll finish this game soon." Uni says without looking away, mistaking Neptune for Noire. Upon realizing this, Neptune decides to prank her sister.

Crouching down, she silently crawls towards her sister, unable to hide her fiendish smile. "Just a little closer...wait for the right moment...~" She mutters quietly to herself, directly behind Nepgear now. Her hands were ready, she thought to herself. Both little sisters were completely focused on the race. It was now or never!

"Surpriiise!" Neptune firmly gropes Nepgear's breasts, squeezing them strongly. "Kyaaaahh!? O-Onee-chan!? W-what are you..hyaaah!~ N-not there, onee-chan..!" Nepgear immediately drops her controller, arms and body twitching and squirming from Neptune's touch. "Ho ho? It seems like my darling little sister has gotten bigger—and more sensitive as well! How cute!~" "Kyaah..!~ I-I don't knowww!~ O-Onee-chan, please..!~ It..it feels...weird..!~"

Nepgear was completely red, but Neptune just hugs her closer. "My cute little sister, I just wuv you so much..!~ I just wish I could...could...ah..hah..? W-what..?" Neptune loses her train of thought suddenly, her mind picturing Nepgear on a bed, completely nude and beckoning her to come closer. And she did, kissing her body, caressing her everywhere...

She shakes her head, banishing the images from her mind as she felt a slight flash of excitement from her body, though she let go of Nepgear before anyone noticed. "Ah, s-sorry Nepgear..I-I didn't mean to be so rough.." "G-geez, onee-chan...don't scare me like that..for a second I didn't think you were going to stop.." She was panting slightly, hand placed over her heart. Uni was just as red as the others, not really sure what to say.

"What's going on here..? Oh, Neptune, you're here! Thank god.." Noire appears through the door, picking up the other goddess from the floor. As she does that, Uni stands up as well, approaching her older sibling. "O-onee-chan...are you feeling alright..? I feel like you've been avoiding me recently.." She asked innocently. Noire looks at her for a few seconds, looking a bit uncomfortable, then leaves the room while dragging Neptune. "T-there's nothing wrong...I just..need some time alone! I'm busy with work!"

Without giving Uni a chance to reply, Noire closes the door, leaving the two younger siblings confused and worried. Nepgear takes Uni's hand in an attempt to comfort her. "Don't worry, Uni-chan, I'm sure you'll be able to get closer to Noire in time..." Uni nods slowly, a bit depressed. "It's alright...it's just, I get a bit jealous whenever I see Neptune shower you with attention...and seeing you much closer to your goal than me.." Nepgear and Uni look at each other, then smile. "Come on, let's go take a bath, Uni-chan. We'll think of something for sure!~" Uni agrees happily, and they leave the room.

"So, what does our lone wolf Noire need from me so suddenly?" Neptune asks, sitting next to her friend on her bed. Noire looks down, flustered from earlier. "I told you, stop calling me a lone wolf! This is..very serious..and hard to explain...do you know of anything odd happening recently?" "Odd..? Uh, I don't know...w-what exactly do you mean by that?" Neptune answers, thinking about the xxx-disc, but not really wanting to say it. "Odd, like..." Noire thinks, then sighs. "You know what, never mind..I'll just show you..you're the only one who'll know this, okay? Here..here goes.."

Noire lifts her skirt, and Neptune gasps. She had the exact same new asset as her. "Y-you have one too..!?" "Too!? What, you mean..?" It was Noire's turn to be surprised as Neptune lifted her own skirt. They both blushed deep red, avoiding eye contact.

"W-well, I suppose you've been through the same troubles as me..." Noire said, breaking the silence. "Ah, umm...I-I don't know...it didn't seem so bad once Compa started helping me. Oh, but you've been keeping it to yourself as usual, so of course it's only troublesome to you. Why don't you talk to Uni about it?" Noire's face flushes as she hears her sister's name. "U-Uni..!? N-no way, I can't...not when the xxx-bar is so close to full..!" "The xxx-bar? Oh, I only found it this morning...and it seems like it's at 92%...what does it do anyway?" Noire goes wide-eyed. "N-ninety-two? That's the same as mine...the closer it is to full, the more I get lewd daydreams a-about Uni...I can't control it...y-you?" "Huh..I think that happened earlier..I was thinking about Nepgear...and I was getting excited..."

Both Neptune and Noire look at each other with worried looks. They couldn't bring themselves to ask one thing. What would happen if the gauge maxed out? Their thoughts were already occasionally wandering towards their sisters in various lewd and tempting situations, and it was slowly driving them crazy. "I-I don't understand...i-it's like my body's demanding that i... Do my sister.." Says Netpune as she checks the gauge: 97%.

Now they couldn't even keep their erections down, poking right out from under their skirts. "N-Neptune..w-what do we do..? M-my hand won't be enough if this keeps up..." "Maybe...maybe we should go into HDD mode?" Neptune suggests, and they both agree to try. In a flash of bright light, each transform, Neptune always showing huge contrast to her normal form. The problem, though, was that no weapons or armor appeared along with them. Completely naked, with their cocks hanging proudly. Simultaneously, the goddesses put a hand to their head, suddenly getting a small headache, then their faces go beet red. "Nepgear..." "Uni..."

"So, Uni-chan, any ideas on how to win over your sister?" Nepgear asks as they both rise from the bath tub. "I...I don't know..maybe I should just tell Onee-chan that...eh?" She looks at the entrance to the bath as two people suddenly come in. Realizing who they were, Uni blushes deep red, having almost confessed out loud next to her sister.

"O-onee-chan? Noire? W-what are you...heh!? W-what are those..!?" Nepgear notices their male appendages through the steam. "I-in HDD as well..w-what's..going on..?" Nepgear's voice goes quiet as Neptune goes close to her, then gently pushes her back to the wall. Uni was in the same position beside her, exchanging looks of embarrassment and confusion. The older girls were panting and looking straight in their sister's eyes.

"N-nepgear...we...I need you...please..I must..have you..." "Uni..I-I'm sorry, but...your sister...needs your body..please don't hate me.." Before either could respond, the goddesses steal their lips and kiss them passionately. "Mmh!? Mmmhh..!~ mmmgh...mmmh!~" Arms pinned to the wall, the younger siblings could do nothing to gain the advantage. But that was fine for them. They were finally, though abruptly, kissing the one they loved. Uni even started tearing up and crying as Noire thoroughly showed her what a real intense kiss was.

Five minutes in, their lips finally separate. "O..Onee-chan..hah...you can..do what you want...I..I love you.." Nepgear whispers, blushing and heart racing madly. Neptune nods, pressing the rest of her body against her younger sister, her large and hot appendage pushing against Nepgear's tummy.

Uni looked up to her sister, panting. "Onee-chan...I..I want to help you...w-whatever you want, I-I'll do it..! W-what can i-hyaah!?" Noire suddenly pushes her down to her knees, greeting her with her cock. "Hah...hah..please...lick it...please!~" She says, desperate for attention. Uni blushed darkly, smelling and poking it before nodding. "Y-yes, anything for onee-chan..."

Neptune whispered into Nepgear's ear. "N-Nepgear...I'm barely holding myself back anymore...please..I...I want you...~" While saying that, she rubbed her member against her sister's tummy, losing her self-control. "I-I...okay...I'll help you sis...l-like this..?" Crouching down, Nepgear grabs the stiff rod and strokes it. "W-wow...it's so hard and hot...and it's pulsating strongly...and.." After smelling it slightly, she starts licking the tip, causing Neptune to gasp quietly. "N-Nepgear...more..please..!~"

On Uni's side, Noire was very much enjoying her sibling's tongue. The young girl explored her cock as she pleased, looking to find the most effective areas to pleasure the elder. Nepgear would peek and copy her best friend, making both transformed goddesses moan in bliss.

Unfortunately, the goddesses were now looking for greater pleasure, stopping them and suddenly carrying them in the air, then setting the girls back to back, leaning against each other. "W-wha..? Onee-chan..?" The older sisters held them up with ease, prodding their rods against Nepgear's and Uni's slits. They were both a bit scared of what was coming next, so Neptune and Noire put Nepgear's hand together with Uni's.

"Mhmm..we can do it, Uni-chan. I'm here with you.." "T-thank you Nepgear..I'm with you too-" "Kya!~" They both yelped as the older girls pushed in slightly, just barely touching their hymens. Neptune and Noire kiss their partners and push through simultaneously, moaning in pleasure. "M-mmmhh!~ Nnn..Ne..Nee-chan's...so big...i-inside me..!~", Nepgear moaned, tightly clinging to Neptune.

Uni, on the other hand, was completely muted by Noire's deep kiss and slow thrusts. It seemed too much for her, though Neptune also decided to start thrusting, nibbling at Nepgear's nipples roughly. "Hyaaah!~ It's...hyah..onee-chan's...digging...into me..!~ Onee-mmmmhh!~"

Nepgear's moans were muted by Neptune's lips, kissing her deeply as she thrusts deeper and faster. Uni, on the other hand, finally manages to breathe and moan, her sister separating her lips and tongue from hers. "Fwaah...hah..hyaa!~ hah...hah..Onee..chan...hyah!~ I...I love you Onee-chan...I love you..!~ M-more...use me...however you like..!~", she moaned as Noire's hips pounded her solid rod harder and faster.

The transformed CPUs were relentless in their quest for release. The younger siblings still held each other's hand, squeezing them them quite hard at times when the pleasure was too much. Before long, the sisters' cocks were throbbing hard as they panted fast and closed their eyes. "Nep...Nepgear..hah..I'm...so close..I'm..I'm gonna...N-Nepgear!~" "Uni!~ Uni..yes...so good...coming..it's coming...s-sorry Uni..I can't stop..!~"

Nepgear and Uni moaned loudly at their suddenly agressive thrusting, pushing as deeply as they could until the pink haired girl felt the dark haired one's back shiver and convulse. "H-hyaaah..!~ O-onee-chan...so warm...filling my tummy...~"

Seconds later, Nepgear felt the same flood of lovely warmth spread inside her. "Hah..ahh..hyah..!~" She could hardly speak, Neptune's tender love rendering her mind blank as cum flowed into her orgasming body spurt by spurt.

Neither of the younger siblings remembered being brought to a bed, one layed next to the other. One thing was for sure though: they never let each other's hands go.
