Author notes: Fetch your crosses and holy water ye' thirsty heathens for I hath delivered our most gentle of sins. Smut! / Futanari. This story is for my fellow RWBY trash Michelle, so thank her for this atrocity. As a side note, there's nothing wrong with a little girl on girl action, although in this story Blake has a penis but identifies as a female. Just a friendly warning, there is some mature language along with the frickedy-frack here. If you don't like this please leave now. Oh and the middle part may break apart the pace of this story but I just couldn't write about Blake ravaging Yang like that without a talk about consent. Sex without consent is rape, and I do not condone or will I ever write about it.

Anyhow as per usual likes and comments are much appreciated and yeah I guess, enjoy?

Everything had been a rush of commotion for team RWBY over the past couple of months. They had been caught up with everything from studying, to capturing the notorious Roman Torchwick. It was only now, a couple of weeks before the Yvtal Festival tournament that the group had had their first official break. Each member of Blake's team had decided to use the time as best as they could with Ruby deciding to spend the day with her girlfriend Weiss and Yang out preparing for the festival, all was thankfully quiet in the dorm. Blake had wanted to go with Yang to be ready for the tournament but she had a more pressing issue to deal with; her heat cycle. A short period of time from three days to a week whereby she would have the insatiable urges for sex until the heat cycle ended or until she impregnated someone or was impregnated herself.

At the moment Blake was sat on top of her bed; one hand currently propping up her signed copy of ninja's of love for her to read while the other made slow and gentle movements at the growing bulge inside of her shorts. Her heat cycle had come around sooner than she had expected and now that she finally had the dorm free for the evening; with Ruby and Weiss out on a date in downtown Vale and Yang at the gym, Blake had the perfect opportunity to relieve herself. Wrapping her hand around her hardening member and pulling it out of constrains of her pants she released a low growl as she increased her hand's movement speed.

She was at the chapter where the master sensei was being orally pleasured by their pupil when she decided to close and drop the book so that she could take off her sleepshirt and bra in order to fondle her sensitive nipples which were aching for her attention. Removing her clothing one handed was a challenge but as soon as her fingertips came into contact with her stiff peaks she let out a high pitched moan, pre-cum already beginning to leak out of her cock and onto her other hand, acting as make-shift lube.

Closing her eyes, Blake's mind began to wonder to a certain blonde haired partner of hers... "Yang…." She moaned as she squeezed her breast harder. "Fuck Yang… You feel so good" She wailed as she imagined what Yang was doing now; the girl would most likely be sweating as her large tits swayed from side to side at her motions as she trained. Blake would love to coat the blonde's perfect orbs in her seed, just imagining it made a large amount of pre-cum shoot from her eight inch erect dick. She was close. Very close.

Panting heavily she picked up the motions of her hand… just a little more… That was when she heard it, the sounds of a very distinctive set of footsteps approaching from the corridor. Eyes widening in shock, Blake immediately stopped what she was doing. As quick as she could, she darted beneath her bed's covers, just as the object of her fantasies stepped into the room.

"Hey Blake!" Yang enthusiastically greeted as she walked over to a desk and put down her changing bag, completely oblivious to her partners condition. "Apparently team CVFY have claimed all the training rooms for themselves for some emergency practise before an important mission or something like that. Ozpin even authorised it saying that if students really needed to workout they should use the gym in the meantime. Of course, as soon as I got there the room was packed and every piece of equipment was claimed, so I just decided to take a walk around campus before coming back here and spending the day with you." After receiving no response Yang turned towards her and Blake's beds "Blake? Are you alright?"

Oh crap, Oh crap, she's coming over. Blake thought as Yang tentatively approached. "Aww" the blonde cooed upon seeing Blake's closed eyes and blank expression, "Guess you really must've been a sleepy kitty." She mumbled as she reached towards Blake's face and tucked a stray strand of hair out of the way. She then trailed her fingers lower and began slowly stroking the Faunus's cheek in gentle movements. Blake immediately bit her lip at the gentle contact, feeling her thick member pulse against her hand once more as she tried her best to hide her throbbing erection. It may not have been anything overly erotic under normal circumstances but while under the control of her heat it was enough.

OH FUCK, I-I'M GUNNA CUM Blake mentally screamed just as Yang stopped her motions and walked away. As soon as the blonde turned into the en-suite bathroom and closed the door behind her Blake quickly rolled over onto her hands and knees and bit her pillow to try and somewhat muffle her moans as her seed exploded in thick spurts onto her hand. "YANG HNNNNNNNAAHH, FFU-FFUUCCKKKKK" She screamed as she finished pumping her rock hard length. After briefly releasing a slight amount of her load, Blake turned to her side as she caught her breath, her eyes burning a vicious amber and her ears flattening against her head as the full force of her built-up heat hit her hard.

She registered the sounds of clothes being removed and running water. It made her blood burn hot knowing that Yang was in the next room naked, most likely rubbing a soft, slippery lather over her flawless body. Her instincts were begging her to go to her partner and fuck her senseless but she clenched her hands and eyes as the last remaining rational part of herself fought for control. She couldn't do this to Yang. It was wrong, she couldn't just use the girl as nothing more than a fuck toy for her heat's needs.

To Blake's credit, she had tried so hard. She didn't want to give into her primal instincts but her battle was lost as soon as she smelt the enticing arousal and heard the first whimper echo through the water in the shower and into the bedroom. Yang was clearly having her own fun in the bathroom. Golden eyes dilated and narrowed as Blake was consumed by the inner animal as she stood up and then shed out of her remaining clothes. Walking over to the bathroom, just about to open the door Blake was momentarily stopped when she heard her name being called out in the moment of her partner's passion. "Blake- Ahh Blake! Right there, yes…Mmmnn… Fuck, Blake…."

Her partner calling for her made Blake's cock stand at its full length upon hearing those sweet and quiet murmurs from the usually loud and ecstatic brawler. Choking back a grunt of frustration, Blake opened the door and crept inside without making the slightest sound and started slowly stroking her member at the sight she was greeted with. Yang was leaning against the shower wall with one arm propping a majority of her weight up and supporting her head as the other hand was down between her creamy thighs. The sheer amount of Yang's arousal in the air was almost overwhelming to Blake as she slowly proceeded closer to the unaware blonde until she slid the clear shower door open and stood behind her partner.

"Blake?" Yang whimpered as she went to turn around upon hearing the shower door open then close, before being embraced from behind by none other than her crush. The beast within Blake was craving to enter and wreck the girl before her right there and then but with all the strength the sane part of herself could muster she regained control of her basic functions, barely suppressing the heat. She needed to know that Yang was okay with what was about to happen. She needed her partner's consent. "Sshhh Yang, It- It's okay. I-I can't really explain, but I need you… Do you want this?" Blake worked on mastering her breathing as she could feel that with each exhale, she lost the will to restrain herself from moving her hips the slightest bit forwards and humping Yang.

"I-er… O-Okay" Yang answered cautiously as she nodded her head. "I need to hear you say it. I need to hear you say yes…" Blake grunted as she was about to lose her struggle. "Y-Yes. Pl-Please Blake. I need you" Yang answered with absolution, as Blake's internal conflict ended and the heat finally took over.

Blake wasted no time by sliding her hands around the front of Yang's body, one trailing upwards to grab at Yang's already hard nipples while the other snaked low between her thighs and rubbed harsh and quick circles around the blonde's clit. "Ahhh! Blake" Yang cried as she already felt her first ever orgasm at the hands of another approach hard and fast. "Blake, Fuck! I'm gunna- AHHHH MNNNNAHHH" She screamed as she hit her high. After a moment, Blake removed her hand from between Yang's legs much to the blonde's disappointment. The Faunus then moved to lick Yang's moisture that she gathered on her fingers into her mouth. Dust. The girl tasted good.

Panting from her orgasm Yang tried mumbling her appreciations. "Blake that was so good… You- You were my first…" She confessed with a blush glowing red on her cheeks. "Oh, Yang… it's not over yet" Blake growled as she removed her own fingers from her mouth to nibble at the back of the brawler's neck and shoulders as she pressed her full body against the back of the blondes. Yang gasped in a large amount of air as electric shocks coursed through her system with Blake's rough treatment and because she felt a hard object rub against her lower back. "Bl-Blake Ahhh, what-what is that!"

Blake span the blonde around to face her then trailed her hands down both the girl's sides until she reached her thighs. "You're about to find out…" As soon as she felt herself being lifted, Yang wrapped her arms around Blake's neck and nuzzled her head against Blake's shoulder, a strange sensation of comfort and desire flowing through her. Opening the shower door with some difficulty, Blake planned on carrying the brawler out of the bathroom and onto the bed, until Yang made the first move. As soon as they had left the bathroom Yang looked down and was mesmerised at the sight of Blake's huge erect cock sway slightly between their slick bodies. She was curious and excited at the prospect of having the huge member inside of her and didn't want to wait any longer. With a quick thrust of her hips forward Blake's dick was positioned right at her awaiting entrance.

Feeling her tip graze against Yang's velvet-soft pussy was the snap of Blake's self-control. Groaning loud into the air she twisted both her and Yang towards the nearest desk and let the girl beneath her fall backwards so that she was lying down, spread open for her on the table. Wasting no time, Blake leaned over Yang; her arms propping her upper-body above the blonde as she pushed forwards, immediately forcing her first three inches inside the brawler. "Mmmmnnn ahhhh Fuck Yang! You're so fucking tight!" Blake was in absolute bliss as Yang's walls clenched her pulsing cock, however it was not so much fun for Yang. "Blake- Oww, Blake it hurts" Yang cried out as Blake's cock broke her hymen and took her virginity.

Hearing her mate cry out in pain forced the inner-animal in Blake to slow her motions until Yang was ready to continue, she didn't mean to hurt the poor girl. After a minute or two with slow and gentle rocks of Blake's hips the pain slowly faded into pleasure. Yang looked up at Blake and nodded her head as she wiped tears from her eyes, granting her permission to start again. Slowly pulling out of Yang, Blake then picked up the blonde up in a bridal style as she walked over to her bed and laid Yang down and across the sheets.

Blake crawled over to Yang as she lowered her head and kissed the blonde with passion, pouring her emotions and pleading for forgiveness for hurting Yang in the embrace. They kissed for what felt like forever until they were both desperate for breath. Blake growled a low rumble in her chest as she felt Yang reach up and tangle her hand in her own hair and try to claim dominance over her by trying to force her tongue into her mouth. There was no way that Yang was going to be the dominant one, not while Blake was in heat anyway. Biting Yang's lower lip, Blake trailed her hand which had started to fondle with Yang's nipples again, down to the brawler's mound. Stroking her ring and middle finger across Yang's lower lips she felt Yang's breathing start to hitch. "May I?" "Yes, Fuck yes you can"

Blake started by easing her forefinger slowly into Yang's dripping pussy before quickly adding her middle finger into the mix as Yang's whimpers turned to loud moans. "Blake, I think I'm ready. I want you" Blake stopped kissing the blonde as she replied "Are you sure little dragon?" Yang's giggle at the nickname was cut off as Blake crooked her fingers to hit that one spot. "Ahhh, Yes! Blake please!" Removing her fingers from the girl, Blake then kneeled beside Yang to reposition her so that she was on her hands and knees. Yang flushed a deep crimson at the change but said nothing as Blake shuffled down the bed so that she was kneeling between her thighs, her cock once more poised at her soaked core.

Taking in the sight of Yang submitting to her, Blake grit her teeth as she eased her length inside Yang's well lubricated folds. The friction created was absolute heaven for them both as Blake switched her rhythms between short but quick thrusts to stronger and deeper ones. Yang's moans started increasing in pitch and length as Blake picked up a merciless pace feeling more and more pre-cum leak inside her mate. "Blake! I'm close!" Hearing those words Blake leant down so that her breasts were pushed into Yang's back as she fully hilted her eight inches deep within Yang. "AHH BLAKE FUCK AHHHHHH IM CUMMING NYYAHHHH HMMMMNNAHH"

Feeling Yang's walls clench her dick in a vice-like grip and attempt to milk her cock of her seed made Blake bite into Yang's shoulder hard, drawing trickles of blood. "BLAKE!" The blonde calling her name like that, mixed with the way her pussy was massaging her cock was enough for Blake. Clenching her jaw even harder against Yang, Blake's load exploded. Her extremely loud moans were thankfully partially muted as she thrust as hard as she physically could inside of the blonde as her seed burst out inside of Yang.

Then just as quickly as it came, the heat was gone. Opening her clenched eyes, Blake felt like a foreign, burning presence had been quickly deflated inside of her as she came to her senses. After taking a minute to compose herself, she realised that she was still biting Yang's shoulder with an excessive force, so as gently as she could, she let go of Yang. Leaning up onto her knees again, Blake felt guilt stir in her system as she could already begin to see bruising form from where her fangs had deeply penetrated the skin. Looking away from the claiming mark, Blake noticed how the blondes head was buried within the pillows and her back jutted in little movements as she breathed in quick, deep breaths but thought nothing of it.

Removing her softening member out of Yang as gently as she could, Blake saw her cum begin to leak from inside Yang's abused flower. Amber eyes widened and her stomach dropped at the realisation. She had cum inside Yang, with no protection…. Blake's mind went blank as she tried desperately to try and figure out what this meant. The bite mark... The heat being over so quickly… Fuck…. I might have impregnated Yang…. OH SHIT….No… This isn't happening…No. Fuck… Please…No….What have I done?
