Fetishes in this chapter: Futanari, mild bondage, and mild stomach bloating

Cheesy spy music played in the background as Neptune sneaked over to Noire's door. Getting in hadn't been easy, as she had to sneak past Uni. In reality, Uni noticed Neptune several times but just wrote it off due to Neptune being, well, Neptune. The moment she got in front of the door she kicked it open, hoping she'd find the tsundere in some sort of cosplay outfit, or even better, changing out of one. "Supriiiise, Noire!"

Suddenly, before Neptune's leg even returned to the floor, something black wrapped around it, pulling her entire body into the room. "It's not much of a surprise when you do this each week, Neptune." The CPU said almost smugly, as the object that bound the girl's leg began to spread, holding both of Neptune's legs and binding her arms around her back. It forcefully bent her over, keeping her legs spread apart as the black completely-not-tentacles dug into the ceiling, holding her in position as the raven-haired cosplayer watched on.

"Nepu!?" The lilac haired girl shouted as a actual-tentacle latched onto her leg and forced her into the middle of the room before binding the rest of her limbs, spreading her legs, and bending her over. The surpriser was surprised. "S-say Noire, uh, what's up?" The girl started to feign innocence.

Noire watched with satisfaction as Neptune was bound and unable to move, the girl who always came around whenever she tried to dress in cosplay now having things flipped on her head. Figuratively, at least. "I think we both know you didn't come here just to visit, Neptune." With her grin plastered on her face, she moved over to close the door that her fellow CPU so rudely kicked in. "Do you really think you could get away with busting into here every time I'm changing, did you Neptune?"

Neptune felt a shiver go up her spine as Noire called her out. "W-whaaaat? N-Noire, you perv, little old me would never!" Despite knowing that her bluff working had a chance equally as big as Blanc's breasts, she still tried anyways as she tugged and squirmed against the tentacles.

"I don't want to hear you of all people calling me a perv," Noire's expression shifted, grimacing with a blush as she remembered all the times Neptune snuck in. She either stormed in while she got all dressed up in her cosplay, right as she was about to start, or, worst of all, stepping in right as she finished undressing. The CPU shook her head, as she strolled back around to Neptune's face, a small, singular test tube in her hands, containing a strange pink liquid. "You had to know payback would be coming sooner or later."

Neptune looked at the odd potion Noire held, and ignored her comment on revenge. "W-Watcha got there Noire?"

Noire's grin returned, though there was a distinct blush on her face. She couldn't believe she actually got this, but, it was too late to return it now. "Something I hope will teach you a lesson." Tilting her head back, the CPU swallowed the whole contents of the tube, a touch surprised by the sweet taste of it. She had to act quickly though, as she could feel it's effects immediately. Her hands pulled up the affront of her skirt and pulled down her panties, just in time as something began to grow above her nethers. Suddenly, a thick, meaty shaft shot out, and grew from Noire's crotch. Two feet in length, and easily five inches across, it was a complete monster, something which even surprised the girl it grew from.

"NEPU!?" Seeing the futanari cock shocked Neptune for two reasons. The first reason was because Noire just grew a dick, and the second is that she had read enough fanfiction and doujin to know *exactly* where this was going. Neptune felt a sense of dread looming over her as- "So you aren't Lonely Heart anymore then, you've got a girlfriend: Your right hand!" Nevermind. Instead of dread, Neptune had decided to make a joke that would probably worsen what she had coming.

If something snapped, anyone in all of Lastation could've heard it, their CPU now completely done with what Neptune had to say. "You really love to run that mouth, don't you?" She asked as she placed a hand over the lilac-hair that capped the girl's head. "Well, I wonder how well you'll run it when it's stuffed!" The massive cockhead pressed against her lips, before being forced through. Noire let out a long, drawn out moan as her "friend's" insides engulfed the huge shaft, unwillingly stretching and clamping down on her length. It bulged noticeably from her throat, quickly stretching beyond that as the CPU plunged deeper. It almost felt like her cock was melting, as the warm, squishy insides wrapped around her monster cock, all the way down till Neptune's lips were around her base.

Neptune could tell that there was a line, and she had just crossed it. After crossing it, she threw rocks at it, burned it, blew it up with C4, before calling in an airstrike that dropped a nuclear bomb that split into four smaller bombs and then those each split into four more bombs. "Heyheyheyhey Noire, just wait a sec- Mmmmmff!" Neptune squirmed a bit as Noire kept going down more and more. It wasn't that she didn't want to suck Noire's newfound shaft, but it was too rushed even for Neptune.

If Neptune didn't want to be forced to swallow every inch of Noire's cock at a rough pace, then she should've stopped talking a while ago. Now that she was down at the base, the CPU left it there for a bit to enjoy the feeling, a warm, tight body constricting around the fresh and surprisingly sensitive shaft. It was meant as a punishment, but now Noire couldn't help but find herself a bit caught up in the pleasure. Without a word, she pulled Neptune's head off her length, getting almost completely off, the tip now occupying the girl's mouth again. There was barely a second to enjoy the taste of her cockhead again, before it was thrust back down, the raven-haired girl raising the volume of her moans as she took the plunge once more. Her pace was brisk, still not used to having a cock, especially one of such size, and was steadily working her way up to quicker, more powerful thrusts.

Neptune let out a grunt that was suppressed by the present shaft in her mouth in response to the aforementioned shaft reentering her throat. Neptune's throat grew an obvious bulge as Noire's cock repeatedly slid down her throat. After a few more thrusts, the girl being assaulted had given up whatever resistance she had and started to lick whatever part of the shaft she could.

The comparatively small tongue only covered a little of the massive cock's underside, its movement severely limited by the size of the intrusive member. Noire meanwhile was quite enjoying herself, her hands now resting on Neptune's head as she plunged in and out of her. What was initially a steady pace was quickly growing faster, and the CPU's lips collided with her captor's crotch with more and more force.

Neptune's mouth took in the shaft, oddly enough, in a slightly tsundere mood. Her tongue acted like it didn't want to lick the shaft, but would then have short bursts where it licked all around the areas she could lick. Out of instinct Neptune tried to move her hands to grab Noire's butt for support, but her hands were still locked in place by the odd tentacle esque appendages.

With the not-tentacles keeping Neptune bound, there was nothing she could do to move any specific body part. Her tongue could only move as much as the massive cock would allow, and her head was effectively kept in place as that same shaft was impaling it much of the time. However, Noire could only hold on for so long. Her cock began to twitch and spasm, her thrusts became erratic and sped up. The warning signs were there, before finally she sheathed herself one last time, just as an ungodly amount of cum shot through the shaft, and copious amounts of the thick, white cream shot down right into the CPU's stomach.

Neptune's body shook and shuddered as the cum flowed down through her body and into her stomach, causing Noire to earn a lovely groan from the lilac-haired girl. Noire couldn't hear Neptune's muffled voice over her own, as her moaning voice reverberated through the entire room until she finished pumping cum into her friend. She pulled out after a few minutes, the last, thick ropes of cum being cleaned off in the girl's mouth as the thick shaft sprang free. It was still fully erect, and though Noire was still catching her breath, the almost glazed look in her eyes said she wasn't done with her just yet.

Neptune took a few deep breaths as her mouth freed up before looking towards Noire, only to see her glazed over face. "N-Noire, w-wait a sec! I-Isn't once e-enough?" Even after having been cum inside of with such force, Neptune still managed to hang onto most of her upbeatness and energy.

Noire didn't respond, finally getting her strength back as she moved around behind Neptune. The, let's face it, tentacles almost immediately tore apart the girl's clothing, shredding everything that covered her nether regions. The moment they appeared, the CPU practically ponced, not waiting for them to finish removing the rest of the girl's clothes. She simply slammed her hands down onto the girl's exposed rear, and with only a split second of lining up the shaft, slammed her entire length into the girl's womanhood.

Neptune blushed as her nethers were exposed. "Uwah!? Atleast take me out to a nice dinner first NoiREEEEEEEEE!" Just as she was finishing her joke, Neptune's body was slammed foreward with Noire's force as the shaft slammed into her nethers. Neptune's body began to spasm and shake in response to the immense pleasure that overwhelmed her.

Noire's voice joined Neptune's as they screamed in pleasure, the bindings of the girl straining at the immense force of the CPU's entrance. They held firm though, and braced for the next push as the girl pulled back. She didn't allot the same time to get used to her shape to the lilac-haired girl's womanhood as she did her throat, simply slamming in as quickly as her body would allow. Her body and bindings stretched around her size, the latter doing its best to not snap under the immense strain.

Neptune moaned out loudly and bucked her hips. She was barely able to properly respond to the waves of pleasure crashing into her sanity, other than crying out, "Noire! Noireeee!" Every time the shaft made a bulge present and hilted itself inside the small CPU, Neptune moaned out.

With every powerful thrust, the girls' moans mixed together and echoed through the basilicom, and Noire only got louder as she grew faster and faster. A small, still thinking part of her almost wished she'd gotten a second helping of the potion she drank, so she could've had even more cock to brutally fuck her companion with. But that little voice did little else but muse, as the CPU's prime focus was entirely on the heavy thrusts that reshaped Neptune's insides. Noire's speed was nearly supernatural, thrusting several times into the smaller girl per second. Neptune's tongue hung out as she called out again, "Noire...!"

The glaze of Noire's eyes were all that she had to give as a response, as she continued to hammer her fellow CPU full of cock. One had to wonder just how long they'd been fucking, considering the only thing either of them could truly focus on was the cock and the pleasure it brought on. Any sense of time went out the window, and there was no telling just how long it took before Neptune's stomach began to inflate like a balloon, even more cum now pouring into her womanhood.

As Neptune's stomach started to bulge slightly from the cum filling it she cried out one last time as she shuddered in pleasure, she herself reaching her own orgasm, "Nowaruuuuu!"

Noire, in what little semblance of mind she had left, tried to respond this time, trying to yell out Neptune's name as well, but somehow she was able to articulate even less than her. Her words only came out as pleasured gibberish, as she leaned over on top of Neptune. Her erection had finally calmed down, and she simply left it lying deep within the girl, cum pouring out from around it and pooling at their feet. Her breaths were heavy and weighted, as the CPU was now about ready to pass out from her own lack of energy.

"Nepu..." Neptune tried squirming and obviously failed. If Noire passed out now, then Neptune would be stuck like this for a loooong time, so Nep tried provoking Noire a bit, "Man, even when you're mindlessly humping me... You're... You're stull too tsundere to say my name, heh."

"Sh-Sh-Shu... Shu..." With her presence of mind slowly coming back to her fading consciousness, Noire barely had the strength to even form words correctly. "Shu-Shut up, Neptu..." The CPU didn't even finish, her voice trailing off as she passed out completely. The tendrils remained still and Neptune was still filled with her friend's monster cock, unable to get free until she woke up again.
