Yang returned to the RWBY dorm to find quite a sight. It had been a rough day – especially her gym time, which was somewhat complicated by her recently elevated center of gravity – but Blake on the other hand, after offering numerous profuse apologies to Port, Ozpin, and Jaune had been instructed to take the rest of her heat cycle off. Yang had wondered what her partner would do with the time off, or indeed if she was safe from the tentacle Grimm - called an Ursula if her Grimm studies book was to be believed – but upon opening (and very swiftly shutting behind her) the door to her dorm, Yang realized that those probably weren't the right questions to be asking…

Blake was on her hands and knees, nightgown hiked up over her waist. Her bow was off, her cat ears flattened against the top of her head, and her eyes were shut, face equal parts flushed and frustrated. Yang blinked a few times before she comprehended the behavior – and noticed the open vent in front of which it was taking place – before it sank in. Oh…

"Hey Blake… You… okay…?"

It was like Yang had thrown a switch – albeit perhaps a partially jammed switch – because Blake's reaction was instantaneous, if not quite complete. Upon being addressed – as though she hadn't even noticed Yang enter the room – Blake had shot up from her presenting position onto her knees, cheeks crimson with embarrassment, though she couldn't quite keep her hand from wandering to the space between her legs, "Y-Yang! H-hi… I was… I was just…"

"It's okay…" Yang assured, kneeling down in front of Blake, "You can't help it…"

Relieved by the way that Yang seemed to understand, Blake resumed pumping her two fingers into herself, sending a thousand little twitches of pleasure over her face. For a long while Yang just sat there watching as Blake pleasured herself; first two, and then three fingers in her womanhood, all the way up to the knuckles as she worked them around inside herself, trying to get the most out of it. Yang felt herself get hot just watching, and her panties started to feel wet. Blake didn't even seem like she was aware of Yang anymore, so focused was she on working her hips and putting her fingers inside, and as Yang's breathing grew heavy she decided that she couldn't take it anymore. Maybe she was still hormonal after the whole 'getting pregnant' thing, but Yang wanted Blake, and she wanted her now. Judging by the way Blake was shamelessly moaning and didn't seem to notice as Yang took off her shirt, Yang figured that Blake wouldn't mind…

With both hands, Yang seized her partner and forced Blake's lips to hers. The heat-addled Faunus's eyes shot wide at her partners sudden, if not unwelcome advance, but squeezed shut again just as quickly when Yang's fingers reached under her nightgown and began rubbing her clit, and almost instantly she was putty in the Blonde's hands, and happily so. Yang pulled her close, cradling Blake in one arm like an infant as she intensified her ministrations, taking the place of Blake's own fingers inside her yearning dampness. When finally they broke off the kiss, Blake's head rested against her buxom partner's upper arm and she started to purr as Yang continued, and her hands lazily groped to remove the Blonde's sports bra before finally casting the article away and nuzzling up to Yang's wonderfully sizable breast.

"Ah! Ow!" Yang protested as Blake's teeth began nibbling on her right breast, "Kitten… that hurts…" Blake just bit her again, and yang winced, "Well… if that's how it's gonna be…" She retaliated by jamming a third finger inside her partner, who yelped, squeezing her thighs shut about Yang's hand.

"Ah… y-yes!" Blake cried out in pleasure, wrapping her arms about Yang's neck as Yang pumped into her progressively faster, "Fuck yes! Fuck ME!"

Eager to satisfy her lustful partner, Yang continued to bounce Blake up and down on her fingers. Blake's hips bucked in response to each and every thrust, gasping and moaning as Yang's three fingers pumped in and out and the Blonde's thumb stroked er clit until Blake's body seized up, "Ohhh… Ohhh… YES!"

Yang smirked widely and kissed Blake's cat ears as Blake shuddered and came onto her hand, "I do good?"

Blake nodded, but blushed, "…More…?"

Yang blinked, "You… want more…?"

Blake shakily straddled Yang's leg and began to grind herself against the Blonde's thigh, whispering sensually into her partner's ear, "Yang… I'm in heat… I've got about five more days of constant… well…"

Yang nodded slowly, trying to comprehend what it would be like to spend an entire week constantly horny, "How… how much do you want…?"

Blake leaned down to suck the top of Yang's breast until she left a mark, "How much have you got…?"

Yang smirked, interpreting that as a challenge, " How about this?"

Blake yelped again as she was thrown onto the floor and Yang tore the bodice of her nightgown open with her teeth. Had she been in her right mind, this wanton destruction of her clothes might have annoyed Blake, but as it was, Blake really wanted Yang to kiss her, bite her, suck her… and she really wasn't about to complain when her partner started motorboating her chest. Blake's breathing grew faster and faster as yang's hands closed around her breasts and squeezed. It didn't stop there though, as Yang moved lower and lower down Blake's stomach until Blake was left gasping and panting while Yang spread her legs. Yang paused for a moment to appreciate the sight of Blake's quivering pussy before she dove in, and Blake's hands slammed down onto the floor and her back arched as Yang's tongue penetrated her folds. Unbeknownst to the entangled pair though, the guest that Blake had been hoping for arrived through the vent. As Blake writhed in ecstasy and Yang ate her out, one of the small creatures clambered out of the vent and crept toward them, its tendrils reaching out…

"Mmph!" Yang spluttered into Blake's vagina, startling Blake almost as much as the brawler as the tendrils pried her own lower lips open and the undulating mass pulled itself inside her. Yang collapsed with her head on top of Blake's stomach, and the Faunus, unfulfilled, sat up to see why Yang's ministrations had stopped, "Y-Yang? What…?"

As Yang rolled off of her, her golden eyes beheld the last wriggling tendril disappearing beneath Yang's skirt. As Yang flopped onto her back, chest heaving as she gasped, Blake tore her partner's skirt off, in such a hurry was she to confirm her suspicion as she examined Yang's womanhood. It wasn't fair… Why the hell did these things like to tease her so much? She'd lost track of the time she'd spent earlier spreading herself in front of the vents, yet now Yang got it? Really? So. Not. Fair-! But Blake's internal griping was silenced as a thick, black member spilled forth from Yang's vagina and prodded Blake's chin as it became erect.

Blake stared…

"Good god… what…?" Yang slurred, bleary-eyed as she recovered her wits.

And Blake stared….

Yang looked down at herself, and then sat up wit a start when her eyes fell upon her new 'plus one…' "G-gah! What the Hell!?"

Blake licked her lips, feeling the fire light up between her legs again, and she stroked the rigid member causing Yang to flinch, "Yang…"

"D-don't do that! God, that feels weird…"

"Put it inside me,"

"W-what?"

Blake shifted to meet her partner's unaccountably reddened eyes, "What's the matter?" Blake crawled on top of her partner now, nuzzling to her ample bosom, "You know I'm horny Yang… Don't make me beg…"

"B-Blake! This thing is inside me-!"

"And I want it inside me." Blake insisted, "It's perfect… I want you to mount me, and then I want you to fuck me, and fuck me, and maybe fuck me some more… Until I cum… until I scream… until I beg you to stop…" Yang's heart raced as Blake rubbed herself against the new member, sending shivers of pleasure through her, even as the Blonde found it difficult to avert her eyes from Blake's swaying breasts, "And then I want you to fuck me harder, and harder and harder… At least until I pass out… okay? Then you can stop if you really want to…" As if to accentuate the word 'really' Blake twisted Yang's nipple, "But let's be honest… I really wouldn't mind if you just kept right on having me…"

Right then, Yang lost all semblance of self-control and her hips bucked, driving the throbbing black member deep into her pussycat. Blake exclaimed in sexual delight as she sat back onto the driving shaft, her own hips beginning to buck as she straddled Yang. Fucking became the sole effort of the Faunus' entire body as her whole form rocked and swayed from her head to her toes, trying to squeeze the maximum possible pleasure from each and every stroke. Her hips gyrated, then worked back and forth, up and down, side to side, trying to work Yang's long, hard cock into that one perfect spot inside of her. Yang bucked her hips savagely – as hard as she could, as fast as she could – and she was completely and utterly delirious with lust. All she was conscious of was Blake's nearly naked form straddling her own, and the burning need to violate.

With a mighty effort, Yang bucked Blake off of her cowgirl position and onto the floor. Before Blake could recover, Yang was on her again, grabbing her legs under the knees and plowing her silly. Blake tried to be an active participant at first. Wrapping her legs around Yang's waste and clinging to the Blonde as though for dear life. Blake's nails dug into Yang's back, leaving long scratches across the Blonde's finely toned form, and Blake bit down on her shoulder as though to further anchor herself in place as Yang stood, lifting Blake to rest straddling her hips as she continued to thrust. Blake's entire world was reduced to the taste of Yang's shoulder, the glorious 'FUCK YES!' feeling filling her womanhood, and the jostling press of Yang's breasts to her own soft, sensitive mounds as Yang bounced her up and down on her shaft, and she liked it that way. .

As Blake came again though, Yang abruptly pulled out of her, turned Blake around so that Blake could feel Yang's breasts pressing into her shoulder blades, and then promptly resumed the fucking. Yang held her up by the thighs and Blake's arms happily fell limp as she watched her reflection in the window; her own not-insignificant breasts bounced and jiggled wildly as her whole body was jostled, and she could see the thick black column of Yang's member disappear into her folds each time Yang's hips thrust it inside. She wasn't so much a person anymore as Yang's moaning sexual toy, and as she looked into her own eyes reflected in the window, Blake came again, just in time for Yang to loudly groan, and Blake's body involuntarily spasmed as the bulge passed from Yang's pussy to her own, where the hot gush spurted into her womb.

Blake reveled in the feeling of her walls being clamped down on Yang's member for a long while, and enjoyed the look of orgasmic pleasure on her own face, but it wasn't enough… "More…"

Letting go of one of her legs and taking a fistful of Blake's breast instead, Yang Readily obliged, thrusting again even as her cum slowly oozed out of Blake, coating Yang's throbbing length. Yang then dropped to her knees, and Blake fell forward, though not off of Yang's huge, ribbed cock, and Yang took hold of her hips as the thrusting resumed and intensified.

"…Fuck…" Blake moaned like a whore as Yang's cock slammed all the way in, pulled most of the way out, and then slammed back in again, "Ooooohhhhh… I… I feel it ALL!" As Yang's thrusting into her reached a fever pitch, Blake came again, finally satisfied – for the moment at least – and slumped to the ground, legs spread wide for her juices to pool between her legs.

Yet Yang was not satisfied, and as her member twitched in an annoyed demand for satisfaction, it impelled Yang to act.

"Y-Yang… what are you doing…?" Blake asked, the lustful haze having been well and truly fucked from her mind as Yang flipped her onto her back, "Yang, that's enough – stop- AHH!"

And so Yang set about the task of raping Blake Belladonna until she screamed – just like she'd asked her to. An exhausted Blake weakly struggled and fought, but it was no use; she'd told Yang to take her by force, and that was exactly what Yang was going to do. Blake's feeble resistance wasn't just because she felt satisfied though; indeed not. Rather, she had already begun to feel the first consequences of Yang's (the creatures?) cumming inside her. Her breasts ached and she felt bloated, yet as plaintive moans of "S-stop.." and "No more…" gave way to wordless groans, Yang did not let up, and drove her cock home into Blake's pussy once more, and Blake's eyes lolled back in her head as she gave up resisting and her body began undergoing the pregnancy in earnest. Never missing a stroke, Yang bent down over her suddenly passive partner and began to suck at her nipples, heedless as Blake's abdomen began to swell beneath her own. All Yang was in a fit state of mind to care about was that Blake's nipples were hard, and her pussy was soft…

Let's be honest: I'd be perfectly fine if you just kept having me…

And so she did. Yang continued to fuck Blake's prone form even as her stomach bulged and her breasts grew swollen, causing eye-pleasing little jiggles to run across her partner's naked body. Blake's legs twitched as the ravishing continued, as though wanting to wrap around the Blonde and hold her borrowed girth inside, but lacking the strength, and in any event, Yang proceeded to fuck her partner's soft, quivering pussy to her own fullest satisfaction.

"P-please…" Blake whimpered, though she was unable to decide if she really meant it as, even despite her swollen abdomen and breasts, Yang's continued penetration had made her cum a fourth time… "No more…"

But Yang did not stop – not until she was satisfied, letting out a shuddering groan as she – or the Grimmling which had taken up temporary residence within her – she couldn't tell anymore – loosed another stream of hot, white cum into Blake's womanhood. Thusly satisfied, Yang collapsed beside Blake, her temporary member causing her to shiver with pleasure as it slithered inside her, and then cry out in pain as the whole Grimmling inside detached itself and crawled its way out of her pussy. Blake on the other hand, screamed.

She could feel the Grimmlings fighting and slithering all over each other inside her even as the first contraction hit her and her first cry of pain split the dorm. It felt like an eternity as the other contractions followed, but when the time came, she took Yang's hand, squeezed it, and pushed. Blake's first was pushed down and out of her birth canal with painstaking slowness, but she almost preferred that than the way that the second couldn't seem to escape her womb fast enough, spilling from her pussy, onto the floor, and skittering away as its last two brothers fought each other inside her for the privilege of being next born. Blake's face scrunched up as they struggled and writhed, getting stuck just short of her entrance, allowing stray tentacles to probe the air beyond her folds. With one final, excruciating effort though, they too were expelled from Blake's vagina and the cat Faunus flopped back down onto the floor and caught her breath as her stomach returned to normal size.

"Y-Yang…" Blake intoned between gasps, feeling her suddenly sensitive and engorged breasts, "G-get over here…"

"Huh…?" Yang lazily looked her way, "Whoa Blake…" She added tiredly, "Nice rack~"

"They're sore…"

"Ya get used to it…"

"But it hurts now!" Blake pouted, "You are so making it up to me next time I'm horny…"

And with that, both partners collapsed into sleep on the floor of the dorm.

Well now… How's that for a nice and intense Bumblebee session? I suppose Blake might do to be careful what she wishes for, but then she is in heat, so she got a little greedy… Anyway, Next up is going to be the Malachite sisters – Yay for twince- Ehem… That said, I'm sorry to say that I can't keep up the daily schedule, so it might be a few days – worry not though, this isn't going anywhere, just slowing down a bit. That said, requests and suggestions are still always welcome.
