Chapter 1: To Love You

Chapter Text

  4 years.

  It's been 4 years since Team RWBY had defeated Salem and destroyed her plans.

  It’s been 4 years since Ruby proposed to Weiss. As well as Yang's, Ruby's sister, proposal to Blake.

  When they got married, the girls opted to get a house together, deep in the woods of the sisters hometown, the Island of Patch.

  Nowadays, they often travel the world as fully realized Huntresses. Slaying the greatest Grimm and saving the world.

  Today, they stalk deep into the jungles of Mistral, hunting another remnant of the nefarious Dr. Merlot and his mutant monster Grimm experiments.

  But first, we find them in a quiet clearing, resting and relaxing in their tent. Doing not so quiet things.

  

  —-------

 

  Weiss squirmed under Ruby's touch, the snow haired beauty gripping tight her lover's luscious black hair as her wife ate her out.

  The tent was quite large, enough for 8 people. A little overkill for 4 women, but they liked the space. Gave them enough room to cuddle. And for other, more intimate things.

  Ruby had undressed the heiress, Weiss now only in her cute blue lace bra, her panties discarded. For Ruby was servicing her beloved wife by eating her succulent pussy for breakfast. The brunette herself was only in her black underwear.

  Weiss laid back on the sleeping bag as she had been asleep only moments before, awoken by the masterful tongue of team RWBY’s leader. Ruby had placed her head deep in between Weiss' thighs, and licked her pussy with glee. Not long after, she slid her tongue deep into Weiss' cunt, reaching for the best spot, the G-spot.

  Weiss quivered as Ruby tasted it.

  “Ruby! Yes! Yes!” Weiss' wife had succeeded in finding her target, and let the heiress know it. “That's it! Ha! Ah! That's- Ha!”

  Ruby gazed at Weiss from between her thighs. The heiress had wrapped her legs around Ruby's head, wanting her closer. The brunette obliged, pressing her tongue deeper into the G-spot.

  “Ahh! Yes! Fuck! Ruby!” Weiss was obviously enjoying it, yelling out her lover's name. Ruby could taste the pleasure spilling from Weiss' pussy, drinking it up happily.

  “Yang, more. I need more. Gah. Yes!”

  To the right of the White Rose pair was the other half of the team, Yang and Blake.

  Blake's cat ears curled and wiggled as she gripped the pillow tightly. She was on her belly, Yang eating her cunt while holding her waist. Both were fully nude, showing off their tan lines from their vacation last month.

  Yang herself was immensely enjoying the meal, licking Blakes delicious pussy, her tongue making the Faunus girl squeal. She couldn't get enough.

  “Mmm! More! I! Need! Mmm!” Blake was insatiable, needing a minimum of 3 orgasms before she considered their sex session finished. Yang was happy to oblige, not wanting to stop until around 5.

  They couldn't keep their hands off of each other, even at home. Everyday, Weiss and Ruby could find them upstairs, making love.

  “Ha! Ah! Hey, mmm, Blake.” Weiss muttered in-between licks from Ruby.

  “Weiss! Hey!” Blake tried speaking under Yang's assault. “Sorry if we, Aah, woke you.”

  “No. Ruby did thaaaa~” Weiss' legs clutched harder as her body tightened. “Ru- Ruby. I'm gonna- I’m gonna-”

  Ruby licked harder and harder, pressing her tongue into the spot.

  This did the trick for the heiress.

  “Cumming!” Weiss yelled, squirting load after load from her climax. She arched her back as she squealed in delightful pleasure.

  Ruby happily drank it up, her lips capturing every last drop. She quickly guzzled it down for the next one. When she was done, Ruby gave her lover a smile that Weiss could feel on her pelvis.

  Weiss had always found it annoying that she excessively squirted a copious amount of her fluids whenever she climaxed. Always making a mess of whatever was in range, like her bedsheets. It made it hard for Weiss to masturbate throughout her life.

  So she also found it extremely hot that Ruby could drink up all of it, enjoying her lover's taste.

  “Oh, Brothers. I need more of that”, Weiss thought to herself.

  As if hearing her thoughts, Ruby returned to eating her wife's cunt. Weiss' head pressed into the pillow, sensitive from her climax. “Ah! Yes! Again! Give it to me again!”

  “Looks. Like. You're. Mmm. Having. Fun.” Blake was breathing fast, Yang’s tongue making her hopelessly horny.

  “I could say the same, Gah, to yo- you, Blake.” Weiss retorted. “What are you, ungh, on?”

  “Round. 6.”

  “Hmph. Show off.”

  “I could. Say the. Same. To you. Miss lace panties.”

  “Ruby likes my, hmm, underwear. So I'm ready whe- Whenever she wants.”

  “So am I.”

  “Like I said. Show off.”

  “Pru- prude.”

  “Pussy.”

  “Mm. Come here. Let. Me. Get a. Taste.” Blake moved herself a little, getting closer to Weiss.

  The Faunus and the Heiress kissed while their wives ate their pussies with glee.

  The two married couples always flirted the line between each other. Wondering where it truly lay.

  So far, it's only been the occasional kiss or grope while being railed by their significant other.

  For example, Blake kissing Ruby while both were getting scissored by their respective wives. Yang groping Weiss while being both were fucked by a strap on by their significant others.

  Ruby and Yang were careful not to do so lustfully to each other. Although, there have been the occasional glances.

  Yang looked up to see Blake making out with Weiss. Finding it cute, she gripped her beloved's glorious behind, and gave it a good squeeze.

  “Mmm.” Blake squealed into Weiss' mouth.

  “Yang! Not too much! I can't take any more!” Blake thought to herself.

  Ruby looked up past Weiss' white bush and saw her wife sucking Blakes tongue. Finding it hot, she reached up. Sliding her hand over her stomach, she caressed Weiss' old scar on her hip from Cinders Spear. She reached further, under the blue lace bra. There, she fondled Weiss' perky breast.

  “Mmm.” Weiss moaned into Blake's mouth.

 “Too soon! I'm still sensitive! I came only a short time ago!” Weiss thought to herself.

  Ruby and Yang could feel they were close, so they sped up their ministrations, and licked harder and faster.

  The kissers couldn't maintain it and broke the locked lips, returning their attention to their wives and the impending climax.

  “Yang! Yang! Yang!” Blake screamed out her beloved's name, her 7th climax nearing.

  “More! That's it! Ruby!” Weiss yelled out her wife's name, her body charged for another load.

  “Cumming! Mmm! Ahhhh!” Both women squirmed and squealed as they went over.

  Blake covered Yang's face in her pleasure, having it dribble down the blond’s chin.

  Weiss squirted again, Ruby drinking it up as she had been. Savoring every drop.

  After a few moments, the sisters finally let up on their wives and rose from the legs of their lovers.

  Weiss was breathing heavily. “Fuck. That was… good.”

  “Oh, you were.” Ruby licked her lips as she crawled over to her wife, water bottle in hand. She laid on her side, spooned against her wife's body, putting the bottle to Weiss' lips. “Here. Drink, Snowflake. You probably came in pints.”

  “Yea. Than ya.” Weiss lazily said, still a little dazed from her double climax. She opened her mouth and drank greedily from the bottle. She was now aware that she was, in fact, dehydrated now.

  Yang spooned Blake from behind, massaging her weary body from all the pleasure of the morning. “Tired, sweety?”

  “Yes. But the good kind. I love you, Sunshine.”

  “I love you too, Moonlily.” Yang kissed Blake on the cheek and pulled the covers over them.

  “Isn't it time to get up?” Weiss asked, the bottle now empty. Ruby was reaching for another when Blake answered.

  “No. It's only 4 a.m., so we can go back to sleep. We have another few hours.”

  “Right. *Sigh*. That was fun.”

  Ruby got another bottle and returned to her embrace. “Yep. Here, drink another.”

  Weiss obliged, drinking the bottle dry. When she was done, she rested her head in her pillow. “I love you, Ruby.”

  “I love you, Weiss.” Ruby kissed the vertical scar that ran over Weiss' left eye.

  Ruby pulled the covers of their sleeping bag back over them before they all returned to sleep.

 

—-------

 

  Hours later, in their combat gear, camp packed up, they had found the laboratory.

  Ruby was in her usual black shirt and skirt, red cape flowing behind her. She had her short black hair with the red tipped highlights flowing in the wind.

  Weiss had gotten out her white and blue combat dress, complete with her signature combat skirt. Her snow white hair was up in a ponytail.

  Blake was in long black pants and a short black shirt that showed off her midriff and the old scar there. Her raven black hair was up in a bun.

  Yang had in her leather biker clothes and fitted her fully charged robotic right arm on. Her massive blond mane was freshly brushed and put in a big ponytail.

  They were ready for anything.

  It was deep in the forest of Mistral, a random iron door made to look like a gray rock. Lucky for them, it was rusty.

  Yang grabbed it and yanked it off the hinges. She threw it to the side with a solid grunt. It landed with a thud.

  She dusted her hands off. “Well, that's that. Merlot’s doors are losing their quality. Last one, I had to at least put in some effort.”

  “They are pretty old now.” Blake noted. “Although it may be because we busted his maintenance bot factory 2 years ago.”

  “This is true.” Weiss confirmed. “The reports of machines delivering stuff around Remnant have stopped.”

  Blake nodded. “Without his maintenance, all of his factories and laboratories will fall into utter disrepair and destroy themselves without us. So we have that.”

  “And that also means whatever monsters he's making will get out and hurt people.” Ruby replied, a determined look on her. “And that's why we gotta find and destroy all of his junk before then.”

  Weiss kisses Ruby on the cheek. “That's my Rose petal.”

  The team leader blushes at her wife's compliment. “Snowflake, Blake and Yang are there.”

  “I know.” Weiss kisses Ruby on the lips, embarrassing her even more. After they stop kissing, Weiss turns to her sisters-in-law. “Alright, let's go. We're burning daylight.”

  “Hey.” Ruby said as she followed Weiss inside. “I'm the team leader.”

  “Ah, they're cute.” Yang giggled as she followed the pair into the doorway.

  “They are.” Blake followed suit inside.

  The four were walking down the hallway towards whatever awaited them. The way was dark, but Weiss had several balls of light floating around them, illuminating the darkness.

  Weiss dusted off her shirt as she spoke up again. “I just hope whatever he's got in here, we don't get caught up in it again.”

  Ruby laughed. “Pfft. As if we’ll fall for any more of his traps.”

  “Like that one where you got caught in his Slime Machine?” Weiss asked.

  The week where Ruby was transformed into a Slime Girl was quite harrowing. Except for the sex. Weiss quite liked the sex. Ruby was very attentive during that time. They had managed to figure out how to install a reverse function on the machine and fix Ruby's condition. So she was completely fine.

  “Ok.” Ruby admitted. “So there was the “one” time. But it's not like you don't like it when I use my Slime Girl techniques for you.”

  Weiss couldn't argue with that.

  They keep the machine in the basement, with all of Merlot's other freaky inventions, in case they needed to use them to fix something. Or be completely irresponsible and use them for kinky sex.

  “I can't be blamed that Ruby is sexy in any form. That's just a divine blessing.” Weiss thought to herself.

  Weiss spoke again. “Well, I should warn Blake and Yang of the dangers as well, because you two have fallen for his tricks 3 times to Ruby's one.”

  Yang shrugged her shoulders. “Well, at least it was nothing. We didn't get anything as bad as Ruby's.”

  Weiss stomped her foot. “You got turned into a dude. That is something!”

  Blake smiled. “Oh, that one was nice. I don't see the issue, nor why you two banned using it.”

  “The issue was you kept the two of us up all through the night.” Weiss answered. “Every night. For. A. Month!”

  Ruby nodded. “Yeah, I got to agree. That was excessive. I could barely get out of bed, I was so tired.”

  Blake blushed, looking away. “Point taken.”

  “Yeah.” Yang patted Weiss on the back. “Ok, we’ll be careful, Ice Queen.”

  “Good.” Weiss pointed her nose up as she continued her walk. “Just saying.”

  They walked for a minute, then Weiss added, “Well, I suppose we can unban it when we want children, but that's it.”

  “Nice.” Yang and Blake fist bumped.

  There was silence for a minute, then Yang asked, “So who's getting the dick and who's getting dicked?”

  After a short tantrum from Weiss, they proceeded down the hallway and reached the inner sanctum.

  There was a large steel door that prevented entry. This one looked tough enough that Yang couldn't simply knock it down.

  “Yikes. That's a big boy.” The blond brawler turned to her wife, Blake. “Anybody got any ideas?”

  The cat girl smiled, knowing Yang was tossing her a bone, since she was the best at getting through security. “I got some. Give me a second.” Blake went to work on a nearby panel, removing the face and connecting her phone to access the controls.

  “How's it look, Blake?” Ruby asked.

  “Pretty good. Same coding as all the other labs.”

  “How predictable.” Weiss shook her head. “Merlot should have put more effort into his security, otherwise all of his crap would fall into the wrong hands.”

  “Uh, babe.” Ruby noted, hand in the air. “I don't think the door is his security. Whatever Grimm inside is.”

  “True.” Weiss looked around. “Eh, I don't feel like making this a protracted fight. Let me get my soldiers out.”

  “Ain't that gonna be expensive?” Yang asked.

  “Yang. Hello, it's me.”

  Yang nodded. “Oh, right.”

  It helped that Weiss was a multi billionaire heiress, who could cover pretty much any expenses the team had. After all, it was her personal VTOL Bullhead that flew them a quarter way across the world to reach this destination.

  The SDC was being managed by Klein, her adoptive father, but Weiss still has access to the accounts. This meant she could buy Dust. Enough Dust for her summoned army.

  Weiss activated multiple magic glyphs and about a dozen Arma Gigas, suits of armor glowing an icy blue wielding greatswords, rose from the ground and readied their battle stance. With another glyph, a dozen Beowolves emerged as well, glowing the same icy blue. Weiss was able to summon creatures she had defeated once before to serve her in battle, and she had slain plenty of monsters.

  She addressed her army. “Alright. You’ll be advancing and killing anything going through that door. Got it?”

  Weiss got a double stomp from everything in front of her. “Good.”

  The door beeped. Blake stood up and disconnected from the control panel. “Got it.”

  “Good.” Yang took a few practice punches, her gauntlets itching for a fight. “Let's kick some Grimm butt.”

  The large doors began to slowly slide to the side, getting out of the way. It was barely open when something came.

  A large, tar-black hand reached its fingers in the crack and grabbed the door. It broke the motors moving the large door and shoved it out of the way, sending it into its slot in the wall.

  The group backed up a little, as the huge Beringal stomped towards them.

  A Grimm modeled after a Gorilla, a normal one stood at 8 ft and was incredibly strong. This one was massive and horrifying, standing 12 ft tall and had two heads instead of one.

  “*ROOOAAARRRR*”

  “... Yeah, Fuck that.” Weiss said. “Get him!”

  

  *Ten minutes later*

 

  The Arma Gigas stood victorious over the body, its blade buried deep in the chest of the Beringal. The monster was already turning into the ink black smoke the Grimm were known for.

  As for the rest of the laboratory, the other Grimm had been dealt with as well. They weren't as big as the first one, but equally as scary.

  Two headed Beowolves, two headed Boarbatusks, and two headed Griffons. All of them much larger than their single headed counterparts.

  There was even a four headed Beowolf, but Ruby quickly dealt with that one.

  What Merlot was working on became obvious. The specifics and methods were still in question.

  “*Sigh*” Weiss sighed. She sat at a chair in front of a console, one of many in the laboratory. “I'm glad that's over.”

  The lab itself was fairly standard. Several cages and monitoring consoles to observe the cages. There were a few machines to the side that could be used for anything.

  “Yeah.” Ruby nodded. “Let's set the charges and get out of here.”

  “You’re already voting it's too dangerous to keep?” Yang asked.

  “We haven't even looked into it.” Blake noted.

  The team didn't notice a new dull motor sound above them.

  “I don't wanna know.” Ruby shook her head. “Better make sure this thing doesn't make anymore of these big guys before things “really” get out of hand. We can probably leave the research.”

  “Yeah. Sounds like a *Grab* PLAN!” Yang was raised into the air by a big mechanical claw that grabbed her by the waist. “HELP!”

  “Yang!” Blake jumped after her, grabbing hold as both women were raised into the air. She started stabbing away at the arm of the machine with Gambol Shroud, her sword.

  A loud whir began to be heard, and something felt off. Then Blake's sword flew out of her hands and onto a steel square. It was some kind of electromagnet, a strong one at that.

  Ruby's scythe, Crescent Rose, and Weiss rapier, Myrtenaster, flew out of their hands too and onto the square. Yang had it worse, as her gauntlets and her robotic arm flew away too.

  “Crap! How dare Merlot figuratively and literally disarm me!?” Yang yelled, punching away at the mechanical claw.

  “Don't worry, babe.” Blake grabbed the claw, hoping to brute force it open. “We’ll, ngh, get, ngh, you, ngh, out of-”

  The arm tossed both women into a large chamber in an upper section of the laboratory.

  “Ah!” Both yelled as they flew in. The door closed behind them, locking in place.

  “Yang, Blake!” Ruby yelled. “Come on, we gotta help them.”

  “Ugh, where are the stairs?” Weiss asked, looking for a way up.

  “Here, let's use the elevator.” Ruby grabbed Weiss' hand and ran towards an opening. They entered and pressed a button inside. The door closed and locked in front of them.

  “...” The brunette simply stared at the door as the chamber didn't rise.

  “Ruby.”

  “Don't say it.”

  “You know that now, if we survive this, I now have an obligation to never let you live this down.”

  “*Sigh* I know.”

  Energy swirled around the chamber, steam clouded their vision.

  Ruby and Weiss held onto each other as they felt every molecule in their body energize, unsure of what was coming next.

  Then, a flash of light and a very eerie sensation.

  Finally, it stopped as soon as it began.

  The door opened, massive clouds of steam rolling out, and Team RWBY stepped out of the chambers, unharmed. But they were definitely changed.

  Things would never be the same.
