"I'm telling you, I really don't think it'll be an issue. You have each other."
Yang smacks your back. "And I told you, even though we're all in each other's pants, the four of us are missing a certain piece of equipment. Plus we like you~"
"It'll just be a week or two at most. I'm sure your four can live without me for that long."
"Yeah, but I can still miss you. Oh, oh, maybe we can work out some time for a facechat!"
"Assuming none of us are tired from, you know, doing our jobs."
"Are you REALLY saying no to watching a livestream of us kissing each other?"
Weiss stomps her heel on the ground, rippling the papery shopping bag she was holding. "Quiet, you two! Someone might hear us!"
"It's fine. Blake's out with Ilia and her new plaything, so this hall is totally empty."
"You still shouldn't be shouting those sorts of things!"
"Fine, fine."
"We can work out some private time when we need to, but for now, let's get into the room. Just because no ones here now doesn't mean it will stay that way."
"Honey, if you would~"
You take the prompt and unlock the door to your personal private room. The one in the hall with no one to bother you, and the one that allows you and any member of RWBY who feels like messing around to enjoy without bothering anyone. As you use your Semblance to unlock the door, Weiss and Yang pop in. Since Blake and Ruby got a turn, today would be Freezerburn!
All of the girls wanted their share of quality time with you after today's announcement. Though it was a little ways off, each team would be given a mission that would send them out to who knows where. That meant that you would be separated from RWBY for a decent while, the first time since you got together. There was no guarantee that you'd have scroll service, or even any time to chat since the areas are supposed to be hotspots for Grimm. It was cute to see them so upset at their loving boyfriend being forced to abandon them, but this also meant that they wanted to satisfy their urges that couldn't be satisfied without a man or some serious creativity.
To be honest, you have it worse. RWBY loved each other, so they'd be stuck with minimum three partners, but you'd be alone. Yeah, your team is cool, but they don't compare to four women who are dtf. No use whining about it, though. Maybe you can guilt them into sending you some videos to get you through the lonely nights.
For now, though, Freezerburn!
You close the door and ensure that it's locked. Before you are Weiss and Yang, looking at each other and deciding on what to do. This was their first one on one (on one) with you, so neither had explored the other's kinks, though they were aware of them. Shockingly, Yang had been quite conservative about teasing Weiss about her love of calling you Daddy. You wouldn't have expected that level of respect from her.
"So…" Yang starts. "I know what *I* want to have happen, but what about you, Weiss? You feel like doing something special?"
Weiss looks away from Yang to find some comfort in you. Holding up her bag, she says, "I have something you'll definitely like, and an extra special plan that he'll LOVE." She looks over to the bathroom. "If you'd give us a moment, Sweetheart?"
"Oh, sexy outfits~ I'm in!"
You watch Yang and Weiss disappear into the bathroom. Amidst the silence, you hear playful giggling and at least one spank. Before you get too into your fantasies of what could be happening behind that door, it opens and out comes your two girlfriends straight out of your fantasies.
Aside from wanting to be dominated and call you Daddy, Weiss had also found a love of dressing like a slut. After years of being conditioned to wear pretty dresses and doll herself up, revealing her body to you was a favorite of hers. Yang… was Yang, and was up for anything that let her show off her figure, though this was probably one or two steps further than she'd allow outside the bedroom.
Last time you enjoyed Weiss' company in such a way, she had worn probably the most stereotypically slutty outfit one could have thought up: a crop top, microskirt, striped bra and panties, and thigh highs. This outfit was much the same, but with an added level of fanservice, further compounded by Yang joining in.
Twintails? Check.
Collar with a small tie? Check.
Button up with only two buttons done up exposing a lacy bra? Check.
Tiny plaid miniskirt? Check.
Thigh highs? Check.
Yang and Weiss posed before you, rocking the ever-classic sexy schoolgirl look. They'd traded in their Beacon uniforms for ones taken straight from a porn shoot, exposing a great deal of their bodies for you. They both struck a pose highlighting their assets, Weiss drawing fingers down her slender frame while Yang lifted her bust. Both wore appropriately schoolgirly smiles, knowing just how naughty they were.
"And class is now in session," Yang says, straddling up to you. Throwing her arms around your neck, she hangs off before pressing her cleavage into your chest and planting a kiss on you. Looking back to Weiss, she beckons her closer. "Come on! You wanna get an A, too, don't you?"
Weiss confidently steps closer to you, making sure to add some extra swing in her walk to tease her skirt some more. She slides in next to Yang and plants a kiss on you as well.
With a schoolgirl on either arm, you fall onto the bed, happy to be alive. Yang runs her finger down your chest while Weiss sits up and climbs onto you. Seated on your lap, she says, "Okay, Sweetheart, I have something very special I want to try~"
"Of course, Princess."
Weiss' face turns to that ever-familiar smirk when she's enjoying her lust. Reaching into her bra, she withdraws an oddly colored Dust crystal. She holds the pink stone up and says, "This is a special synthetic variety of Dust that's supposed to be used in the medical field."
"That's not…" Yang says, looking with awe at the Dust. "No way. It's real?"
You look up at Weiss straddling you, excited by Yang's reaction.
"Yes and no. It's the only type designed to be used solely on the human body, for things like hormone imbalances, blood cell count, and other things you don't really care about. The point is it's safe. Unofficially…"
"It's REALLY an aphrodisiac? Like, for real?"
"It has, in fact, earned the nickname, 'Lust Dust,' but there's even more to it than that."
"Are you for real!?"
Weiss smirks. She channels her Aura into the crystal and creates a pink Glyph. "Just for me. With my Glyphs, I can play a little more. Like so…" Weiss undoes the buttons on her already useless shirt and removes it, then takes off the disconnected collar, leaving her in just a bra. Focusing on her Glyph, she splits it into two and settles them on either breast. "I've only tried this once, but…" Weiss bites her lip as her Glyphs start spinning faster. They glow brighter, causing her to let out a slightly pained, yet satisfied moan, like one during a deep massage.
You and Yang struggle to keep your jaws off the floor as you watch Weiss's breasts expand. As the Dust takes effect, her modest chest grows and grows, swelling in size and straining her bra. Weiss bites her lip as her body adjusts, weight being added to her front side. Her soft pale skin pushes out against the cups of her bra, spilling out until, with a snap, the clasp unhooks. Whereas Weiss was once a healthy A cup, she now sported a strong C, rivaling Ruby and Blake. They still managed to fit her body perfectly, not too big for her slender frame.
Weiss takes a moment to take some heavy breaths. "It's a little… uncomfortable growing them and the swelling will go down after about an hour, but I think it's worth it, don't you?" She shakes her new breasts around, showing that they were still firm and perky, just bigger. "They're also super sensitive~" Weiss grabs her bolstered bust and squeezes, causing her to moan. "It feels so good when I massage them; do you want a turn, Sweetheart?"
"God I love this relationship," Yang says, staring at Weiss' breasts. Tapping you, she says, "Better say yes before I do."
You lift your hands up and grab Weiss' breasts. Immediately, you hear her whimper as you fondle them. You've played with numerous different sizes at this point, but while Weiss' upgrades still weren't the biggest, seeing the heiress break out of a bra was a sight to behold and a joy to feel. Every time you brush against her skin, Weiss lets out those satisfying breaths. Every time you move your hands away, she bounces them up and down, taking all she's learned from watching Yang do the same. Eventually, she climbs off you and switches to Yang, letting a woman's touch assault her overly sensitive body. You and Yang greedily use your time massaging Weiss' breasts, earning her moans and alleviating her soreness. The visual of Weiss Schnee lying down on a bed while four hands assault her naked, extra-filled out body continues until she sings a final note and melts. Her labored breathing only serves to highlight her expanded bust even further, pushing her breasts out with every moan.
When Weiss finally recovers, she looks over at Yang and asks, "So, do you want a turn? I'm sure you of all people know the appeal?"
Yang shakes her head. "Next time. My girls are already huge, and I think we can use this opportunity to fulfill a dream I'm sure our boyfriend's had." She looks at you and winks. "We can make my cans bigger another day, but you now have the unique opportunity to do something you can't normally do. Something I'm sure you of all people also dreamt about."
Weiss squeezes her enhanced breasts and smiles. "You're right. We should make use of this slutty body of mine, isn't that right, Daddy?"
"God I love it when you talk like that~" Yang says, taking off her shirt.
"Of course, Princess. Get down on your knees where you belong~"
"Yes, Daddy~" Weiss sings. She slips off the bed and gets down on her knees. Squeezing her chest together, she ensures that you're nice and hard as you lower your shorts and expose your cock. Seeing Weiss naked surely helped, but seeing her shake around her now-huge tits ensured that you were ready for her to use them.
Weiss lifts up to the perfect height and awaits your input. You grab your cock and direct it in between her boobs, now properly sized for a titjob. Excited at how she could now do so, Weiss begins massaging your shaft with her chest, squeezing her soft, pale skin around your cock. Due to her breasts being extra sensitive, she continues to moan with you as you both drive closer to the edge. Yang tosses off the last of her clothes and starts pleasuring to the sight of the Schnee heiress being used like a sex toy. The filth of her using her father's Dust to make her body more conducive to a man defiling it fills everyone in the room with an added layer of pleasure.
"Now, Princess," you say, preparing Weiss for the finale. She gives a few final rubs before completely wrapping her tits around your cock. Cum spills out from the top of her cleavage, painting her chest with seed. With a few nipple pinches, Weiss joins you in orgasming while Yang stifles her moans.
"Brothers Grimm, that was hot…" Yang says, throwing her head back on a pillow after tightening her legs.
Weiss sits up and lifts her breasts, highlighting their size and the seed covering them. "I feel so dirty. I love it~"
"Oh, oh!" Yang starts. "Before we clean up, we have GOT to compare! Stand up, stand up!" she demands, shooting off of the bed. Weiss climbs up to meet her. Yang grabs Weiss by the hip, draws her close, then pulls her in for an incredibly tight hug. Their breasts squeeze together, Yang's DDDs pressing against Weiss' now-Cs. In addition, their everythings were connected, Yang's stomach against Weiss', Weiss, mound against Yang's, and, after Yang initiates, their lips against each other's lips. Knowing what to do, Weiss casts a Haste Glyph on you, letting you recharge.
You stand at full attention as you watch two beautiful, busty naked girls hold each other tight and make out. Furthering the depravity against Weiss' legacy, you jack off to the sight until coating both girls' chests in cum.
After a nice long shower, Weiss' breasts started shrinking down to normal, though she did have to stuff them into her dress. Naturally, she also skipped her bra. You look forward to seeing your other partners enjoy Weiss' special Dust.
