Roomies for Life (Kuro x Adult Neptune)

Kuro grumbled as he turned to his side only to feel the cold air. This snapped him awake as he blindly looked for the blanket in the dark. He groaned when his hand instead of finding fabric found a warm soft thigh. She just had to steal the blankets… again! This was the tenth time in one week that she stole them!

He sighed and rolled over to see the body next to him. It was a curvier and more feminine one than his. He sighed and knew there was no way to win this nocturnal battle, so he snuggled close to his roommate and fell asleep, despite the fact that he was still freezing.

The next morning, Neptune was sitting at the kitchen table with a small cup of pudding and a bowl of cereal. Her bowl had a picture of a rare species of butterfly on it. It was her favorite bowl.

She was in mid-bite when she heard a grumble come from the bedroom. She turned and saw a disheveled Kuro come stumbling into the kitchen.

"Mornin', Roomie~" she greeted, taking a small sip of her orange juice.

Kuro just grumbled again as he grabbed a mug, started the coffee maker, and made his third-favorite beverage. Once Kuro's coffee was brewed and he took a sip, he was much more alert and he smiled towards his dorm mate; "Mornin'…"

Neptune, however, noticed he was still pretty out of it and quirked an eyebrow; "Yowza, what's the deal-eo, pal-eo? You're kinda out of it this morning."

Kuro swirled the contents of his mug, contemplating on whether or not to tell the lavender haired girl about her blanket-hogging habits. Looking into her eyes, he made his decision, and mumbled something that she couldn't hope to decipher.

"What's that? I couldn't hear ya?"

"Yrr strr e crvres…" Kuro said a little more clearly, but not enough for Neptune to understand.

"One more time for me? Maybe park your lips next to my ear?" she moved her hair away from her right ear and leaned in closer to him. The spiky haired teen sighed.

"You steal the covers at night, Nep. Plus, it gets freezing cold in the room—well, probably because we're both in our underwear when we sleep—but still, the cold keeps me up and it's hard for me to go back to sleep…"

Neptune blushed a bit and stammered; "W-what? That's crazy! Uzume never said anything about that when we slept together…!"

"She did. I was there when she did, but you were too busy with trying to find more 'specimens' for that book of yours…"

"R-really?! Like, for realsies?!"

"Yes."

The girl blushed brighter; "U-uh… w-well, you could've just woken me up. I would've given them back!"

"I did. Multiple times. But within the next ten minutes, you'd take them back again…"

Now, Neptune's face was impossibly red; "I-I… o-okay…"

Kuro looked at his watch. It was half past nine. Their classes started at nine, a full thirty minutes until then. Grabbing his bag, and Neptune's, he walked out the door towards campus, his roommate hot on his trail. She caught up and hooked her arm around his, a habit that he had grown accustomed to. What he hasn't gotten used to, however, was the feeling of Neptune's C-cups squeezing his arm between them.

'Another boring class. Yawn…' Neptune complained in her mind as she halfway listened to the teacher drone on about some mythology about four goddesses. Looking down to her notebook, she realized that she was doodling and her cheeks turned pink at what age drew. It was a strangely detailed drawing of herself and her roommate. Quickly turning the page to hide it, Neptune's mind wandered back to how she met the dude…

Neptune, when she first came to Gamindustri Academy, honestly had no qualms about sharing a dorm with someone else. She would always sleep in the same room, same bed as her sister, Nepgear, and her best friend, Uzume Tennoboushi, whenever she came over. She had been at the co-ed college for almost a week now, but it wasn't until today that she and the other students had been assigned rooms and roommates.

The first thing she had noticed was that the room was a lot bigger than she had imagined. Shelves, a bed, a desk, and two dressers had been provided and she noted that the shelves had enough room to fit all the various possessions she had brought with her and then some. The bed was twin sized, large enough maybe to fit two people if they squished together.

Her eyes were drawn to the other side of the room and to a mess of black hair along with a forehead and a pair of sapphire eyes reading over a boring-looking (to her) novel. Her roommate. He looked to be a tall guy, wearing a brown jacket and black pants with headphones on his head. His side of the room was just as clean as hers, aside from a laptop, and his phone sitting on his desk plugged into the wall.

The boy looked up from his book to Neptune and offered her a small, friendly smile; "Oh, hey. Are you starting in this room, too?"

'Score! Not only does this room look awesome, but I get to share it with this hot pocket of a guy~! Oh, wait, he's looking at me. His lips are moving, he's talking to me.' Neptune squealed in her mind before brandishing her usual cheerful smile.

"The name's Neptune, protagonist of protagonists," she gave a salute and wink, making the boy shake his head while laughing a bit.

"My name's Kuro. Kuro Seishin, but a lot of my other friends just call me 'Icarus.' By the way, that's actually my middle name."

"Alright, then, Icarus. Move over, I'm getting in that soft looking bed of yours~" without warning, Neptune literally jumped into the bed. The sudden action made Kuro nearly drop his book as he glared at her. He decided not to breach that subject and returned to his literature, turning his music back on in the process.

"Awwwwww, yeaaaaaahhh…" Neptune groaned in comfort. She spared a small glance back to him secretly; he was nodding his head to his music (some kind of rock music as she could faintly hear) and reading his book with a small smile on his face. He looked peaceful, and she realized he couldn't hurt a fly. Probably. His arms were kind of big, so she knew he at least kept himself in shape.

She reached over to her bag and unzipped it, withdrawing the first—and only—book she found: her patented specimen book. She went over it once again, thinking about what sorts of new and interesting creatures she may find here.

"What's that?" she heard Kuro ask. Neptune blushed and snapped the book shut. She was a little bit insecure about letting people look at her book. Anyone who did would either scratch their head in confusion, or just laugh at it.

"I-It's my specimen book. I like to go around and take photos of rare types of insects," she explained.

"Cool. It's nice to have hobbies. I'm more of a traditional book type of guy, though," the next few words made Neptune's breath hitch. "Mind if I take a peek?"

'Decision time, Neptune…' she looked pretty hesitant to let him see it, he could tell. He was about to tell her that she didn't have to let him see it before she thrust the book into his arm, the corner causing a light jolt of pain.

Kuro opened the specimen book and skimmed each page, stopping sometimes to stare at a particular photo, but the next thing he did made Neptune smile like a kid at the candy store; "Hey, these are actually freaking awesome! By the way, what's this? Never seen anything like it?"

"Oh, that's a Blue Morpho. It feeds mainly on rotten fruit, but in their larval stage, they tend to eat other larvae of the same species."

"Insect… cannibalism? I've heard it all…" Neptune giggled and pointed at other photos, explaining what kind of bug they are and anything else she knew. The only other person she'd done this with was Uzume, since Nepgear was afraid of bugs…

The day came and went, nothing particularly noteworthy in Neptune's eyes. She scanned the room and didn't see Kuro anywhere inside. But she found his book laying on the floor. Being the good samaritan that she was, she placed it on the nightstand next to his side of the bed, but then curiosity got the better of her and she decided to take a quick peek.

Upon reading and skimming several pages and paragraphs her eyes went wide in mute stupor. Her face was red now due to examining the content.

She fidgeted and reopened the book flipping the pages until she noticed several pages here and there that included 'catching attention.'

'This is… He's been reading some kinky stuff!' she thought. 'Hmm… maybe…'

With that thought, Neptune began reading on and crafting a scenario in her head that she could set up for her roommate when he got back.

Kuro walked down the hall close towards his own dorm room.

Kuro swiped his room key and entered the room. He immediately kicked off his shoes and was going to dash straight for the bed in their room, ready to just sleep the rest of the day away, but he stopped from doing so when he caught something that shocked him to his core.

"Nep?!" he said aloud causing her to turn her face him locking her beautiful violet eyes onto his cerulean ones, but what really caught Kuro's attention was what she was wearing. His nose trickled a bit of blood when he took in the sight of her; she was, well, naked. Literally clad in only her striped panties and a small white apron that hugged her body.

It was a sight to behold, given that Neptune was already attractive to begin with. Having that apron on and nothing underneath stirred up a bit of arousal within Kuro.

Shaking his head to clear himself of any dirty thoughts, he pointed a shaky finger at her; "N-Nep! What's going on?! Why are you naked?! Why and what are you baking?!"

Fidgeting slightly, Neptune walked up to him, close enough to press her bust against his chest; "Don't worry about that, Roomie. Just sit back, relax, and let good ol' Nep take care of ya~"

He didn't get a chance to retort as something was lodged in his mouth. The ever so satisfying flavor of strawberry entered his taste buds, and he hummed in approval; "Hey, this is good! It tastes like what my grandma used to bake before she died. What's your secret?"

Neptune closed one eye and angled her face, giving him a rather cute wink despite her current… state; "Trade secret. If you're good, maybe I'll tell ya later~"

"'If I'm good?' What do you mean by that, Nep?" he set his left arm akimbo with a smirk. Kuro tried to make small talk as to get his mind out of the gutter. "And since when were you of the cooking type? Last time I checked, wasn't it Gearsy who handled the food-making?"

"What? Are we playing Twenty Questions?" Neptune deflected his question with another, causing the boy to suck his teeth in annoyance. "Besides, I can cook, too!"

"Heating up instant ramen and making bologna sandwiches do not count as cooking…" he stated flatly. Neptune turned around to face him and pouted, to which Kuro responded with a shrug of the shoulders.

Five minutes passed and, thankfully, the growing bulge in Kuro's pants had died down. However, it didn't stay that way for long as Neptune suddenly got situated on his right thigh. Literally, the second she did, his pants began getting tight again. She smirked at this.

"Ohh, Roomie~" her arm hooked around his neck as her chest inched closer to his. She nabbed a strawberry, pursing her lips around it, and leaned closer to him. "This one's just for y-o-u~"

The fruit touched his lips and Kuro decided to just play her game and wrapped them around it. The second he did, Neptune jumped at her chance and used her tongue to push the strawberry into his mouth and promptly initiated a steamy make out session.

After a few moments, she separated from him as to let him actually eat the strawberry. She would've went for another one of the fruit had Kuro not leaned forward and kissed her softly. He caressed her face with one hand and ran his hand through her hair. His lips felt so good on hers. She almost instantly got daring and prodded his teeth with her tongue, requesting a deeper kiss. He slowly slid his tongue into her mouth and they deepened the kiss, tracing each other's lips and, caressing their tongues.

Eventually, the necessity for air overrode their arousal and they separated. Deciding not to dawdle, he undid the top part of Neptune's apron and let it drop. With her breasts now exposed, he moved in and captured one of them inside his warm mouth. Neptune welcomed the feeling and strained her face in pleasure, her breasts were a sensitive part of her and she hoped the boy would continue his ministrations. He pursed his lips, gently sucking in the rosy pink tip he was currently on while his left hand softly fondled the other breast in firm rotations.

While her nipple was inside his mouth, his tongue flicked and licked it and also circled around her areolas, spiking her sensitivity and causing Neptune to jerk her legs a bit. She mewled inwardly with pleasurable delight as his left hand increased its strength and speed in fondling her other breast.

Kuro's mouth detached from her left breast and transitioned over to the other one once again suckling one of her tits into his mouth treating her nipple tenderly. The other mound he had just abandoned wasn't left unattended, his right hand slid up and groped the fleshy orb in its palm fondling it the same way as the other one.

"Hhnnaaggh~~" Neptune hollered out in ecstasy feeling her orgasm approaching quickly due to his expert treatment of her breasts. He had decided not to ignore the other parts of her body by moving his left hand down her side around to her buttocks. Her lower body was quivering in anticipation for what he would do with it as he slid a finger into her pussy, curling it upwards to continuously rub against her g-spot.

The girl's eyes went wide when his index finger slowly wormed its way into her cavern and that is when her body set itself off.

She screamed loudly in ecstasy, her pussy muscles convulsing sporadically and her body thrashing on the chair. Kuro moved back a bit to take a proud look at his work. After a few more seconds, Neptune's body ceased twitching as she calmed down from her climax and looked back at him.

"Bed?" she asked.

"Bed," he responded, agreeing to the change in scenery. They immediately bolted up from the seat and straight towards the bed.

Kuro was seated on the edge of the bed with Neptune kneeling between his legs. She slowly unbuttoned Kuro's pants after removing his belt. His penis started to harden as the fly unzipped, letting it breath as she pulled down on his briefs.

His erection was standing tall in front of Neptune's face, something he never thought would happen. She slowly pushed her tongue out from between her lips, making contact with the bottom of his shaft. He nervously flinched as she leisurely made her way to the top. She suckled on his head for roughly fifteen seconds before taking most of him in. Her mouth was warm and immediately inviting. His breathing had picked up already while she began sucking up and down his cock.

Neptune continued to pleasure him with her tongue, waiting for his rush of semen to pour down her throat. Soon enough, Kuro's throbbing cock released his large load into Neptune's mouth. He ended up ejaculating a lot of semen, dispensing a huge flow of it along her throat. With the semen and Kuro's cock still inside her mouth, some of his cum spill out of her mouth, roll down her chin and onto the floor in front of her.

After enjoying her little "treat," Neptune then pinned Kuro down and aligned the head of his dick with her quivering cunt. She smirked, lowering her hips inch by inch down onto his hardened tool. Her soaking wet and tight snatch enveloped his member bit by bit till she reached the hilt thus completing insertion.

Neptune cried out in both pain and pleasure at having her virginity taken. She didn't mind it, however, because she had long since had a crush on the guy she was riding and she couldn't be any more elated that she could have him take her first time.

"Time for a rodeo~~" Neptune says with an eager tone. Her hands resting on his bare torso, her eyes closed with her mouth agape and smiling in bliss as she rode Kuro for all he was worth. Kuro himself felt like he was in heaven. He didn't want to question his fortune in having this happen to him. He planned to just enjoy this girl's lust addled advance. He could ask questions about it when they were done.

Her tits bounced and her body rocked with him grabbing her hips to thrust up against her bucking body. The two had continued on like this for what felt like forever.

Eventually, Kuro's head inched forward to capture one of Neptune's breasts in his mouth, his lips pulled her left nipple in to tenderly suck on it. This caused unimaginable elation into her body much more so than he thought. It went without saying that her nipples were a sensitive spot. He kept one hand at her back to keep his upper half close to her chest as she continued bucking against his lap.

"This… I-I… I'm… gonna… I'm. Going. To… Cum!". She arched herself back and wrapped her arms around Kuro, her thighs clamped hard on his hips just as her snatch squelched and convulsed on his appendage.

"Aaahhhh! Cummiiiing~!" Neptune shouted as her orgasm finally arrived. Kuro felt her pussy muscles clamp down hard on his cock desperate to milk him for everything he had to offer. His climax hit him like a brick wall in the same way Neptune's hit hers, resulting in a mutual orgasm.

About thirty seconds later, Kuro lifted up Neptune and positioned her in front of the door. He turned her around to where she was pressed against the door. Her modest breasts squished up against the frosted glass as he stood behind her lifting her right leg up and guiding his stone hard member to the dripping, quivering sweet spot that was her snatch for one last romp.

With a grunt Kuro's length prodded apart her moist pussy lips eliciting a quiet moan from Neptune, he slowly drove it further and further until he buried to the hilt then began slowly pounding his hips against hers.

"Aah~! You feel so much harder than before~" Neptune's body rocked to the rhythm of her lover's thrusts, her breasts kept getting pushed up against the surface and pulled back a bit in sync with her body's undulating movement. In her mind, she was in nirvana and wanted it last forever.

Kuro leaned in close enough so he could cup her face and bring it to his, engaging in one more deep kiss. Her leg hiked up a bit as she shifted her body to face his more while he continued slapping his hips against hers. The tight fleshy crevice of her vagina repeatedly close in on his length signaling that it was ever closer to the end.

He picked up her other leg and wrapped it around his lower back accompanying the leg that was already there, she got the message and locked her ankles together at the same time she locked her arms around his neck. Kuro's hands rest at her hips and firmly grabbed them, giving him full access to slam his hips at a more aggressive rate.

Neptune welcomed the sensation of his cock burying itself to the hilt every time. She showed this when she moaned her excitement and undulated her body against his rampantly. After a few more minutes, both of them felt their body muscles tighten and they both came spectacularly.

Neptune arched her back and energetically undulated in Kuro's lap, her inner walls clamping down wildly with juices spraying forth. Kuro hit his limit too and tensed up, sending rope after rope of his essence into her depths and filling her womb to the brim.

After several minutes of post-coital rest, Kuro slumped back against the bed with Neptune laying on top of him. Neptune's cunt seeped out some of the boy's essence as she rest on him. They locked eyes once more and pulled each other into another deep make out session just as nightfall hit.

It happened again…

Neptune shifted over to her right, the blankets shifting over and off of Kuro. The boy shivered once he felt the cold air and tapped Neptune on the cheek; "Hey, Nep…"

"Mm…" she responded.

"Can I have the blankets back?" Kuro asked, but was surprised when Neptune actually shifted on top of him with the blankets covering them both.

"Much better…" she murmured with a tiny smile. She pecked Kuro's lips before shifting into a more comfortable position. "G'night, Boyfriend~~"

The boy smiled with her and hugged her closer to his body, finally glad that he didn't really have to worry about the whole blanket problem for a while now.
