A/N: So uhh, yeah....mind break tag, I guess? Enjoy.

Blake Belladonna was a new comer to Vale's sort of society, and has slowly began to integrate herself into the social atmosphere of Beacon Academy. After leaving the White Fang and getting a fresh start in her life, she finally felt like things were going to work out for her in the long run. Blake began making new friends, though she didn't really try and her current friends were the ones who came to her first, but she managed to befriend a good amount of people and got to know more and more about her fellow Beacon classmates. However, this time of year was problematic for her as she was at the beginning of her heat cycle, causing her hormones to run rampant, especially her libido. To keep herself restrained from causing anyone harm or ravaging any males she came across, Blake would escape to the depth of the library knowing that barely anyone visited the building of text and knowledge. However, there was a small problem for her this time as there was an unexpected event standing before her. Sitting at a far end of the library, was the person she knew was most popular among the girls at Beacon for being the most handsome first year to join Beacon. Y/N L/N, leader of team T/N, who have quickly gone up in popularity at around the same pace as Blake and her own team, team RWBY. Everyone in Beacon knew about the background you came from as the line of huntsmen and huntresses in your family are renowned as the most famous and most incredible warriors to ever protect the lands of Remnant. When you arrived at Beacon, everyone already had high expectations of you and the results you yielded did not disappoint as you were already being requested to accompany third-years and a few professors on missions and expeditions that no other first-year ever had a chance at getting. Being this popular however, you did not get a lot of time to do what you wanted and no one really knew about the hobbies or other activities you enjoyed and you were strangely more reserved about your personal life than anyone expected. The fact that Blake had managed to bare witness the sight of you being alone was already more than shocking to her, but she was also confused as to why you were alone since everyone knew you were always busy doing something. Taking a closer look while walking into the library, a surprised look plastered her face when she saw a small stack of four books next to you as your eyes darted through the pages of the one you were currently reading.

"He likes...to read? Well, I guess with all the work he's had to do, he can't get much reading done. I wonder what kind of books he likes..." Blake wondered before growing even more interest when you suddenly stood up and placed the book in your hands on top of the stack to your right.

Without noticing it herself, Blake had hidden herself slightly behind one of the bookshelves near her and watched as you picked up the book stack and walked over to the counter where the elderly librarian lady was currently working. The elderly woman turned to you with a sweet smile as you gave her a smile yourself and handed over the stack of books to her. What surprised Blake even more was when she saw the librarian put the stack of books in the 'Return' pile for sorting.

"Wow...He really likes to read..." Blake thought as she saw you disappear into one of the aisles of books and she went over to the librarian counter. "Hey, Merideth." Blake spoke up as the elderly lady turned to her.

"Ah, Ms.Belladonna. Back for another reading session?" The librarian said with a smile as she walked up to Blake as the cat-faunus turned to see you looking through the books closely.

"Yeah, you know me...Um, Merideth, how long has he been here?" Blake asked as the old lady looked pass her to look at you.

"Oh, Y/N? He's been here since I opened the library." Merideth said while bring up a small stack of books to sort out.

"You open at 8 o'clock and it's 5 in the afternoon. You're telling me that the pride of us first years, Y/N L/N, has been here for over 9 hours?" Blake asked in disbelief.

"Well, it would seem that today Mr.L/N has free time to spare, and it's nice to see younglings like yourselves spend it with your noses dug into some good old books instead of those fancy scrolls and computers you have nowadays. You see this stack..." Merideth placed her hand on top of the stack of books you handed in with a proud smile. "...He started this series today and just finished." She said with a hint of proudness as Blake was almost jaw-dropped.

"No way..." Blake said as Merideth saw you with a perplexed and troubled look on your face.

"Why don't you help first-year classmate find a new book to read. Seems like he's not finding anything interesting." The librarian said as Blake immediately tensed up.

"U-Uh, I don't think that's a good idea, I'm um..." Blake didn't know how to explain that she was currently entering her heat cycle and came here to try to avoid especially boys.

"Oh, don't be so shy." Merideth said before looking pass her and ringing a small bell on her desk. "Y/N deary, why don't you come here for a moment, please?" Merideth managed to catch your attention.

"Is there something I can help you with?" You asked while heading over, only to grow somewhat surprised look when you saw Blake. "Oh, hi." You said while walking over and standing next to Blake.

"H-Hi, I'm Blake--!" Blake was cut off when you extended out your hand and spoke up.

"Blake Belladonna. I've heard of you and team RWBY. It's an honor." You said as Blake looked at you with a pink hue slowly creeping on her face.

"N-No, the honor is all mine!" Blake was about to shake your hand, but stopped herself to hold back her hormonal urges as you just shrugged it off as nothing.

"Ms.Belladonna here is a regular here at the library, so I thought that if you were having some trouble finding something to your liking, then maybe she could help you find an interesting read." Merideth said as you turned to Blake with an ecstatic look.

"Really? I'd truly appreciate it." You said as Blake turned away and speed-walked away.

"S-Sure, follow me." Blake said as you just followed behind her while Merideth smiled watching you two disappear into the library.

"Ah, the joys of youth..." Merideth said as she placed a 'On Break, Back in an Hour' sign on her counter. "...Good thing I know she's in heat. I'm sure she and Mr.L/N are going to make a story that will never leave this building for as long as it stands." The librarian said with a humorous laugh as she walked off towards the exit of the library.

After weaving through the aisles to find a section Blake felt like she could recommend something good to you, there you were standing in the very back of the library in one of the corners of the building as you looked to see yourself in the fiction section. The selection of books piqued your interest more than the others towards the front of the library, but as you were looking through the books, Blake suddenly came walking towards you.

"Hey, I think I found something you might like." Blake called out as you turned to see her walk up to you with three books as she handed them over. "Personally, they're among the books that I've really enjoyed reading recently through the years. I think you'll like this one." She said as you took a look at the title of the first book.

"Man with Two Souls." You repeated the title as this was already enough to hook you. "I think I'll read this. Thanks for the recommendation." You said as you sat down on the floor, surprising Blake.

"Eh? You're gonna read here?" Blake asked as you nodded your head.

"Yeah, back here it's a bit more uhhh...Isolated? There's this sort of big open space noise back towards the front that just didn't really feel right for me when reading. I think back here's a bit better." You said as you placed down two books on your left and pulled out some earbuds when you noticed Blake sit across from you.

"I uhh...hope you don't mind...I also kind of like it back here..." Blake lied as that wasn't really the reason she was back there, and she didn't know what she was doing due to her heat really beginning to affect her rationality.

"Not at all. What are you gonna read?" You asked as you looked at the book in her hands. "Ninjas of...l-love?" You said in surprise of the title as Blake blushed a bit and hid her face partly behind the book. "A romance story?" You asked her.

"Y-Yeah...Something like that..." Blake said as she struggled to keep her composure.

Blake watched as you pulled out a pair of earbuds and connected them to your scroll to listen to music while reading. Just the sight of seeing the earbud's rod enter the hole of your phone made her begin to think about such dirty and indecent thoughts. What held her back though was when she saw how deeply intrigued you already were with the book she suggested. Usually when Blake recommends a book to someone, she usually just suspects they won't give it any thought and will just forget about book in general. So when she finally encountered someone who was willing to listen to her and her interest, it felt nice and heart-warming. Smiling a bit with joy, Blake decided to hold out as best as she could, and indulge herself into the book she was holding. However, the moment she opened the book to a random spot since she had already read it before, Blake forgot about certain contents in the story 'Ninja's of Love' , and she ended up opening an page that had art on it. Immediately, a dark red hue covered Blake's face as she saw a very spicy piece of art that had a female busty female ninja with a hunky male ninja mounted on top of her and the only thing they were wearing were their ninja masks as all parts of them were not hidden by the shadows. Blake felt her loins become greatly soaked and rubbed her legs together to stimulate her pussy to relieve herself a bit, but slowly her mind began to change the image she was looking at, and she began to imagine you and herself in that position. Slowly raising her eyes, Blake stared intently at you as her mind was beginning to slip and all of her morals were being flung out the window one at a time as she bit her lip while slipping one hand down her pants sneakily to touch herself while imagining you pouncing on her. Whilst reading, you could feel a strange burning sensation on the left side of your face as you raised your eyes a bit from your book to see how Blake was doing, and the moment you did, shock filled your eyes when you saw Blake with her eyes closed and an extremely lewd look on her face as you saw her hand down in her pants. You were beyond shocked seeing what she was doing as you didn't think she was the type of person to do such an indecent thing in public, let alone with someone right next to her.

"B-Blake...!?" You called out as Blake's eyes shot open and she looked mortified in front of you as she pulled out her hand that had a dripping liquid fall to the floor. "I-I'm sorry, I should go..." You said as you picked up the stack of books and you got up to leave.

"W-Wait!" Blake suddenly leaped from her spot on the floor and tackled you to the ground as you were mounted by her and hot breaths left her mouth as she stared at you with lust. "It's not...what you think...! I'm not...ngh!" Blake trembled as she was almost grinding on your leg, but went wide-eyed when she felt your hardened cock through your pants. "Did I...make you like this...?" She asked while sliding her hand down and palming your cock through your pants as you suddenly felt weak to her touch and trembled.

"B-Blake...wait!" You said as you mustered enough strength to grab her by the shoulders as you also had a deep blush on your face. "W-We can't do this!" You said as Blake continued to rub your cock.

"I'm sorry, Y/N...You see, I'm in heat..." Blake said as you felt your heart drop from this new information she told you of as she began grinding herself on your leg. "Can you help me...please? You liked what you saw, right?" Blake asked as you got close to your face and your mind was heating up so fast you couldn't think straight as you two shared hot breaths.

"W-Wait...I haven't...W-We haven't even gone out..." You mewled as Blake made you look into her lustful eyes as you felt like puddy in her hands.

"Don't worry...I'll make you feel real good..." Blake said as she completely lost herself and her heat took over.

Diving forward, Blake pressed her lips against yours and slithered her tongue through to explore your oral cavern. You couldn't believe what was happening, the strongest first year student at Beacon who was renown for being one of the strongest warriors at the academy and could take on any grimm that crossed paths with him, was completely powerless against a faunus girl in heat. Despite your protest, your body didn't seem to agree with your mind as your dick grew harder and larger in your pants, begging to be free. You thought there was something wrong with you, wondering why you were feeling so much pleasure even though she forced herself onto you, or perhaps you subconsciously wanted this because you can't remember the last time you had a girlfriend. Truth be told, you were still a virgin when you came to Beacon, but it seemed like Blake was about to change all that for you as she undid the button to your pants and practically ripped them down your legs as she pulled away from the sloppy kiss as you were left dumbfounded with your mouth open as Blake dripped some of her saliva into your mouth to keep you entranced on her. Using her hand down below, Blake managed to slip your dick out of your boxers and she smiled widely and salivated from the sight of it, but what surprised her was when she saw some precum form at the tip of your penis.

"Y/N, are you...?" Blake slowly looked at you as your eyes tried their best to look away as Blake's eyes glistened with excitement and hunger. "Don't worry...I'll make sure your first time will be the best." Blake said as slowly wandered down your body.

"...W-Wait, Blake...I'm not ready to--AH~!" You mewled and trembled when a warm liquid dripped onto your dick.

You felt like melting as you turned your head to see Blake dangling her tongue over your cock and dripping strands of saliva onto the tip of your penis that ran down your shaft. After getting it nice and slippery for herself, Blake leaned closer to it and began licking your tip like the top of an ice cream cone as her hand wrapped around your cock and went up and down the base, making slippery noises with each stroke she gave you. Every time Blake would lick the tip of your cock, she would make sure to press the tip of her tongue on the slit opening of your dick to make you feel even more tensed up and shocked. Bringing her other hand down, she began to fondle your balls before she let go of your shaft and you went wide-eyed when your entire cock was engulfed in warmth as Blake shoved her head down all the way to your crotch and deep throated you, tightening her throat around you over and over again. You could feel her tongue swirling around your cock and her throat squeeze the tip of your dick again and again as the amount of stimulation was too much for you, and cum erupted like a volcano from your dick, coating her mouth and barreling down her throat. Blake began sucking the life out of you as it felt like you couldn't stop cumming, to the point where cum was overflowing out of the small gaps around Blake's mouth as she continued to suck hard and fondle your balls. Her eyes rolled to the back of her head as she finally came up for air and more cum sprayed onto her face and hair as she smiled lustfully as your cum explosion finally calmed down.

"I-I can't...m-move..." You twitched on the ground as Blake loomed back over you with a cum covered face as she grabbed you by the chin.

"Look, Y/N...you fucked my throat so good..." Blake said as her saliva and your cum drooped out of her mouth and onto your chest and neck. "Your cum is so good...you should try some..." Blake said as you got scared of what she was implying.

Before you could protest, Blake dropped her head down towards you and gave you a hot sloppy tongue kiss, making sure to mix her saliva and your cum back into your mouth. You were beginning to lose it and strangely began to moan as the cum that was covered on her face, began to smear against yours as strings of your cum connected yours and Blake's face. Blake's tongue was spreading your jizz all throughout your mouth as reached a hand down and began stroking your growing erect cock again. Blake smiled when she heard you begin to moan as she pulled away, strings of cum stretching before breaking between you two as she smiled at finally managing to break you.

"Hey, Y/N...You'll help me with my heat problem, right?" Blake asked while leaning down and licking your nipples as you moaned and the smile on your face grew wider and the shine in your eyes left.

"Yesh...Mesh me up good..." You said as your face was wet with saliva and some of your cum leaking from your mouth as Blake pulled away from your nipple and removed all her clothes.

"Don't worry, baby. I'll make sure you won't be able to fuck any other girl other than me." Blake said as she took her panties and gagged you with them before placing her soaking wet pussy on your meaty shaft.

Being in a back corner of the library meant that the airflow for cool air was limited and with you two engaging in such heated actions, your bodies were covered in sweat to the point you could see the beads of sweat on your bodies. Blake leaned down and pressed her boobs against your chest as she raised her ass up in the air, letting your cock stand tall as she couldn't take it any longer. Having enough of waiting, Blake scream led in with excitement as she stabbed herself down onto your cock and moaned loudly as it filled her pussy all the way to her womb and she could feel you almost tear your way into her baby making room.

"OHH GOD!! YOU'RE SO BIG!! SO FUCKING BIG!!! AHH!" Blake's eyes rolled to the back of her head as your eyes almost went completely white from the unbelievable amount of pleasure Blake's pussy gave you. "More...I need it MORE!!" Blake yelled in ecstasy.

Blake raised her ass up until the tip of your cock was barely inside her pussy and right after stopping there, she slammed back down on your cock. Over and over the sound of skin slapping against each other was heard in the corner of the library you were in and with how hot it was, your skin would stick to each other and peel away with an erotic noise as Blake bounced as hard as she could on your cock. Wanting to get more of a reaction from you, Blake had a devilish idea seeing as she had mentally broken you, and turned around to ride you reverse cowgirl without getting off your cock. The cat faunus licked her middle finger to get it nice and wet before gliding it down pass your balls and began to tease the flesh around your asshole. You went wide-eyed when you realized what she was doing, and before you could muffle a word, Blake pushed her middle finger inside of you. You moaned out of shock and strange bliss when she pushed her finger inside of you, and she kept thrusting her finger back and forth inside your ass while she bounced her sweaty butt up and down your cock. The shock from being penetrated must have given you some strength, because your hands slowly raised up to the air and you slammed them down onto Blake's ass, making her moan in shock.

"AHH~!" Blake yelped when she felt her ass get slapped, only to smile and turn back to look at you. "Yes. This is the only pussy you're going to fuck. Your cock is mine, got that? You're my little fuck toy." Blake said possessively as she added another finger inside of you, gently stretching you out.

"B-Blake...! I'm gonna...!" You mewled as you began to thrust your cock up harder and faster into her as your dick kept getting through to her womb.

"You're gonna cum? Huh? You're gonna fucking cum like I want you to, puppy?" Blake said as she giggled when seeing you huff breaths like a dog. "Fucking cum inside me! Give me all your fucking cum! I want you to try and knock me up! FILL UP MY PUSSY TO SATISFY MY NEEDS!" Blake yelled as she squirted all over your cock and legs.

"I'M CUMMING!!" You yelled into her panties as your cock exploded an even greater amount of cum inside of Blake.

Blake went wide-eyed when she felt the rush of cum suddenly fill her entire insides out, and your cum burst out of her pussy and overflowed. She began to twitch and drool from her mouth as the amount of semen entering her was too much even for her being in heat. Blake fell back and laid on top of you with her back against your chest as her fingers pulled out from your ass and your cock popped out of her pussy, still spurting cum onto herself and you. Blake smiled when some landed on her face at the end and once you finally stopped cumming, she turned over to lay on you stomach to stomach as she pulled out the panties in your mouth and your tongue fell out with a dumb smile on your face as Blake smeared her cum and sweat covered face all on yours, and began to tongue fuck your mouth. You moaned in ecstasy as Blake pulled away and drooled onto your face, spreading it around as she grabbed you by the chin to make you look at her eye to eye.

"Who's bitch are you?" Blake asked sadisticly.

"Yours..." You replied happily.

"That's right...the strongest first year is my bitch. From now on, you can only take missions when I give you permission, understood?" Blake asked as she lightly slapped your face.

"Yesh...ma'am..." You said as she slapped you again.

"No, not ma'am. You call me 'Mommy' from now on. Got it?" Blake asked as she found it so satisfying to completely dominate you.

"I understand...Mommy..." You said as she grinned before giving you a quick kiss.

"Good. You are to act normal around everyone else, but when it's just you and me..." Blake trailed off as she traced her hand down and gripped your sensitive and flaccid huge cock. "...You're mine. So remember, this is a story you are NOT to tell anyone about." Blake said as you weakly nodded to her.

"Mhmm...I won't tell the story, Mommy..." You replied as Blake smiled before tongue kissing you once more, savoring the feeling of making the most popular first year in Beacon her personal fuck toy.
