Summary
     Keen on getting more silver eyed warriors, Professors Ozpin and
     Goodwitch hit on drugging Yang, Blake and Weiss with aphrodisiacs and
     doing the same to Ruby while also giving her a pill to grow a penis.
     Truly the most logical and ethical of plans. A commission for
     HeWhoWasMarduk
The door to Team RWBY’s dorm flew open, revealing a stack of boxes with legs.
As it came into the room, Weiss, Blake and Yang followed. Only a few feet into
the room, and the boxes fell with a clatter, revealing the girl’s leader, Ruby
Rose. She hopped up and down, clutching a foot a box had landed on.

“Ow, ow, ow, ow! Stupid box,” she kicked the offending container, rocking it up
before it dropped back down. Weiss rolled her eyes as Yang laughed.

“You know, I offered to carry some of those, sis.” Ruby waved her off before
crossing her arms and trying to look mature.

“But I’mthe team leader. And Professor Ozpin gave them to me. Therefore, I’mthe
one to carry them.”

As Yang and Ruby started bickering about leadership versus actual upper body
strength, Blake opened one container and took out a small bottle of pills.

“Uh, guys? These are mostly empty. There’s only a few bottles in this one.” She
tossed the bottle in her hand to Ruby, who turned it around in her hands,
looking it over.

“Aura Boosting Pills. Take two every twenty-four hours. Looks like there’s
about three dozen in here. What’s in the other boxes, Yang?”

The tall blonde straightened up from the box she was crouching over. She waved
a bottle with a red lining.

“Looks like this one is for you, sis. Says ‘For Team Leaders Only’.” Yang
tossed the bottle to her half-sister while taking one for herself.

“What, really? Oh, and it’s red too. Cool.” Ruby busied herself with her bottle
while the other three girls each thumbed out a pill and examined them.

Weiss rolled one between her fingers before popping it into her mouth. She
quickly swallowed it before huffing.

“Well? What are you waiting for? It doesn’t taste like anything, and we can
always use a boost for Aura. I wonder how…” she trailed off, muttering about
possible Dust combinations as she stared at the plastic bottle, willing it to
give up its secrets.

The rest of the team followed her lead, popping their pills, a slightly larger
one in Ruby’s case, and swallowing them. They all stood around for a few
minutes, seeing of anything was happening or their Aura was changing.

Ruby noticed it first, the larger pill coursing through her smaller body. Her
pale cheeks flushed with heat and she started fidgeting. Only a few minutes
after she started squirming, the other girls started glancing around the room
and shifting their weight from side to side as well.

Ruby turned as red as her cloak, before dashing up to her bed, rose petals
trailing behind her. She buried herself in the mess of blankets as her
teammates shared confused glances. Eventually, Yang rolled her eyes and climbed
up after her, with noticeably less speed and grace. Lifting a sheet up, she
peered under it at her sister’s dim form.

“Hey, hey Rubes. You all right?”

If she was alright, she was doing better than Yang. She was feeling frisky all
of a sudden, like when she went out for a night on the town. She’d actually
been glad to have been selected to be the one to go up and talk with Ruby,
since Weiss and Blake were looking very tasty, even more so then usual.

“No I’m not, Yang! I’m feeling all… pervy and gross.” Ruby shook herself,
facing away from Yang. She didn’t want to look at her sister, for fear of what
the sight might make her feel. Just the sound of her sister’s sultry voice…

There was a throbbing in her crotch, and Ruby felt her body shift as she
thought about her sister. She groaned, a hand diving past her waistband into
her skirt as her body changed. Yang, worried about her sister, started forward,
wrapping her arms around Ruby in a hug.

“Ruby?! What’s wrong?” Yang peered over Ruby’s shoulder, down at her lap, the
building heat between her thighs forgotten for the moment.

From underneath Ruby’s ridden-up skirt, Yang could see a bulge rising. She’d
seen that sort of thing often enough, with the way she dressed, but that had
always been in guys. For a minute, she literally couldn’t grasp the what it
meant, the rising tent, and Ruby shaking.

“Ruby Rose! What are you doing with-with-what do you think you’re doing young
lady!”

Yang recoiled back, but her arms were still wrapped around Ruby. So all that
she accomplished was pulling Ruby back into her. Ruby’s head landed in between
Yang’s large breasts. For Ruby, it was quite the feeling. Surrounded by large,
soft mounds, with Yang’s clean smell, with just a hint of gas from her
motorcycle, and the heat radiating off her body… Her newly made cock rose to
its full, throbbing length.

Yang’s hand brushed against Ruby’s skirt, feeling the long, hot, hard shaft
even through several layers of clothing. It seemed like it was a good cock, a
really good cock. And she, all of a sudden, was in the mood for a good cock.
And she loved Ruby, right? She’d always looked after her little sister, and
now, and now, they could both help each other out. Yeah. When you put it like
that, nothing at all was the matter. It was completely natural that they help
each other out.

Her hand drifted back to Ruby’s crotch. As she made contact with Ruby’s shaft,
her sister straightened up with a gasp, pulling up some of the blankets and
letting more light come through. From down below, moans drifted up, the sharp
sounds of Weiss and the deeper groans of Blake. Yang fleetingly wondered what
the two of them were doing before she closed her fingers around Ruby’s
straining shaft. She knew how Weiss felt about Yang’s partner. She was sure the
two of them could find a way to entertain themselves.

Ruby groaned at the feeling of Yang’s long, strong fingers touching her. Yang’s
generous cleavage pressing against her head, her breath ruffling her hair… Her
legs kicked against the mattress as her arousal surged. Her clothes felt close
and stifling underneath the heavy blanket, and she swept her legs to the side,
knocking the blanket off the bed and down to the floor.

Yang reached down to unclasp Ruby’s skirt as her sister writhed in her arms.
Sliding the black and red ruffled skirt down Ruby’s legs, she licked her lips
at the sight of Ruby’s rod straining against her panties, that, oh yes, had a
little red bow on the front of them. Her pale skin contrasted nicely against
the dark material of her leggings. She had fat thighs, though a quick grope
confirmed that she had lots of muscle underneath

“Yang, what, what are you doinnnggg?!” Ruby’s voice trailed off on a high note
as Yang slipped a hand inside her panties.

Her strong, sure fingers wrapped around Ruby, and went up and down in a slow
stroke. Ruby’s feet kicked against the bed as she fell back against Yang’s
chest. She moaned, feeling the heat of Yang’s body and hand, and the softness
of the breasts pressing against the back of her head.

All of a sudden, the corset and blouse she was wearing felt stifling hot. Ruby
unlaced her corset so fast her hands blurred as she shed, first rose petals,
and then her clothes, falling back into Yang’s arms wearing only her panties
and leggings. Her breasts, only small compared to Yang’s, swayed with the
motion, and her nipples were as rock hard.

Yang picked Ruby up and spun her around so they were facing each other. An
eager grin crept across her face as she looked down at the shaft that had poked
out of Ruby’s panties. And the rest of her little sis looked fine too. How did
I not notice Ruby hitting puberty? Damn, she looks good! But as tasty as Ruby’s
bouncing breasts, and toned abs looked, the real prize was her brand new cock,
precum leaking out of it and staining Ruby’s panties.

Yang scooted forward, trapping Ruby’s cock between their stomachs. She gasped,
feeling her sister’s dick pressed against her skin. It looked so good, and felt
so good, and she bet it would taste so good as well. Shrugging out of her
jacket, and pulling up her yellow shirt, she let her twins hang free. She
guided Ruby’s hands up to cup while she undid her belt, and was forced to rip
off her shorts when she couldn’t get them down far enough.

Ruby was gently exploring Yang’s breasts, rubbing and massaging them as they
rested in her hands. The large, fat nipples on them were hard and wrinkled and
pressed against her fingers as she glided her hand over them. She lowered her
head and sucked on one, enjoying both the mild taste, and the gasp from her
sister.

Leaning into her sister, Ruby gently pushed Yang down to the bed. Her cock was
hard and aching, rubbing precum against Yang’s abs. As Yang wrapped her legs
around Ruby’s waist, keeping her there, she reached down with one hand to rub
Ruby’s cock against her soaking wet folds. They both gasped as the feeling ran
through them.

Ruby thrust her hips forward, trying to sink into Yang’s warm, inviting folds,
but her angle was poor, and her cock merely ran along her sister’s lower lips.
Ruby whined, and thrust her hips forward again, this time sliding into Yang’s
welcoming center. Yang moaned, low and sultry as she felt her walls be split
apart for the first time in far too long.

Ruby slid to a halt inside her sister, gasping for breath. She’d never felt
anything like it before, the heat, and the pressure, and the wetness squeezing
around her as her new shaft throbbed. Yang reached up and pulled her down,
wrapping her arms around her in a hug. Parting her lips, she kissed her sister
on the mouth, gently exploring her mouth with her tongue. The two girls pressed
against each other, limbs, body and mouth as they explored each other.

Ruby slowly drew her hips back, before sliding back in. She’d never felt
physical pleasure like this before. It seemed that her entire body was burning
up, fire racing through her veins as Yang’s center gripped her length. Her
breasts pressed against her older sister’s as they kissed each other, arms
holding each other as they tangled themselves amidst the sheets of Ruby’s bed.

Ruby pulled her head back and moaned, her face bright red. Her hips were moving
back and forth very quickly, slamming her new addition into Yang again and
again. Yang clutched at Ruby’s back, her fingernails scoring red lines along
her skin. Between her legs was a sticky mess, arousal from both of the sisters
flowing out and staining the sheets as their lusts rose higher and higher.

Yang pulled Ruby back down to pepper her neck with kisses. Her locked legs kept
Ruby buried deep inside of her as she nipped at her sister’s tender skin. Welts
formed as blood rose to the surface as Yang marked her sister as her own. Ruby
made adorable yips each time Yang scraped her teeth along her skin. The light
pain was an intriguing contrast to the pleasure of being buried in her sister’s
welcoming folds. Finally, she relaxed her legs enough for Ruby to start
thrusting again.

Ruby was desperate to get some relief; the growth between her legs was a
burning ache that still felt so good. Enclosed by Yang’s wet heat, the gripping
walls were squeezing her length. Her body burned, telling her to thrust as fast
as she could, to get some relief from the burning in her loins, but she knew
just enough about sex, picked up here and there, to know it felt even better if
she waited, and took it slowly.

Contenting herself with long, slow strokes, Ruby leaned her head back down to
devote attention to Yang’s amazing breasts. She trailed kisses down Yang’s neck
and shoulder, arriving at a large, quivering breast. Ruby started to suckle at
a nipple, running her tongue over it as Yang squirmed beneath her. They were
marvelous breasts, really, large and soft and heavy, the kind of thing that
really turned heads, especially with how much cleavage Yang showed off. Ruby
had always hoped that Yang got those genes from their dad, and one day she’d
start blooming like that as well. But for now, she could work out two years of
breast envy by playing with her older sister’s chest.

“God, Ruby, how are you so good at thissss?” Yang moaned as her younger sister
slowly turned her into a pool of lust-filled jelly. “You, you have a girlfriend
I don’t know about?”

Ruby ignored her sister, just grunting around a full mouth as she lavished
attention on Yang’s bosom. She switched breasts, bringing a hand up to take
care of the one she wasn’t taking care of. Now that the initial mad rush of
lust had passed, she wanted to make sure her sister felt as good as she did.
Hesitant, covert fumbling with her own chest in the middle of the night had
shown what felt good, and Ruby used what she’d learned to try and bring
pleasure to her lovely older sister. Gentle strokes around a nipple, firmly
grabbing an entire breast, and more as she lavished attention on Yang’s
excellent bosom.

She started to move again, sliding in and out of Yang’s tight, grasping center
as her sister moaned underneath her. Ruby joined in, feeling the unbelievable
sensations of heat and wetness and pressure surrounding her new, sensitive
member. She cupped Yang’s cheeks as she raised her head back up to kiss her.
The sweet feel of her lips against her sister’s was a soothing balm to Ruby’s
burning body.

Ruby slid a hand between their bodies and slid it down to where they were
joined. After a few fumbles, she found Yang’s clit. Just a touch against it
made Yang arc her back and hiss through her teeth. Ruby pressed down with her
thumb, making Yang hiss and shake her head.

“No, Ruby, no, that’s too rough! Just, just rub against it.” She gasped as Ruby
obeyed her. “That’s right, just little circles.” Yang shuddered as Ruby found
the right pattern.

Ruby kept lavishing Yang’s breasts with attention as she slid in and out of her
sister while rubbing her clit. Ruby’s own pussy was gushing arousal and precum
was coming out of her lower head. Her firm breasts were rubbing against Yang’s
stomach, and her hard nipples were sending constant jolts of stimulus through
her body. The core of her body was tightening up, squeezing around a phantom
intruder.

Yang’s groans grew deeper and deeper as her little sister kept on fucking her.
Cute, innocent little Ruby, who she’d always watched out for and protected, was
now filling her up so good. It was so much better than her fingers, or the toy
under the bed, or the few guys she’d fooled around with back at Signal.

Starbursts went off in Yang’s head as she came. A ragged scream ripped out of
her throat as her fingernails scored Ruby’s skin. Her pussy clamped down around
Ruby, and her limbs locked her sister in place, buried deep inside of her. Ruby
moaned, low and sultrily, as she was finally pushed over the edge as well.

Jet after jet of cum shot into Yang, painting her insides white as both girls
screamed out their climax. Ruby’s pussy squeezed down around nothing, as her
new cock burst with feelings, painting Yang’s insides with her love. Ruby
collapsed onto Yang, her breath hot against Yang’s skin. Her entire body was
shaking, legs twitching and chest heaving as arousal crept out from her
untouched center. Cum slowly dribbled out between them, staining their legs and
the sheets.

“Love you, sis,” Ruby muttered, as she panted for breath. She peppered Yang’s
cheeks with kisses as she slowly wilted inside of her sister. Her heart was
overflowing with emotions, lust and love and affection and more as she gazed
down at her sister.

“Love you too, sis” Yang responded, her eyelids fluttering as a wave of
exhaustion crashed over her. All of a sudden, she felt tired, like she’d spent
all day training or fighting Grimm. She closed her eyes, just to rest for a
minute, and drifted off to sleep as Ruby lay on top of her.

Professor Ozpin leaned back in his chair and nodded. He glanced up to his
second in command, professor Glynda Goodwitch, who had been watching the video
feed with him. One of the many screens showed the half-sisters collapsed on
Rose’s bed, fitfully stirring. Another showed Belladona and Schnee trying to
use each other to work off the lust they were feeling. A third screen was a
reminder of the effects the lust drugs given to the team did. Goodwitch nodded
in satisfaction.

“It looks like the project is going well. The drugs are working well enough,
and Miss Rose’s enhanced stamina should insure she’s able to impregnate the
rest of her team. Ozpin, are you sure any children will inherit her special
abilities?” The headmaster of Beacon took a sip from his mug before responding.

“Quite sure. Everything is going as predicted.”

Goodwitch managed not to roll her eyes at the typically cryptic statements of
her boss. Instead, she focused on the screens, where there was fresh movement.

“It seems that Miss Belladona will be the next one, professor.”

They both watched as the black haired girl staggered over to the bunkbeds to
pull Ruby out.
