It was the start of a new weekend at Beacon Academy. Ruby awoke from a long night of 'team-building exercises' to find that half her team was nowhere to be found. Where'd those two run off to? Ah, well. Weiss is still asleep. Maybe I should feed her a nice sausage for breakfast… At that moment, Yang emerged from the bathroom, naked save for the towel wrapped around her head. Or maybe I could have some milk... "Oh good, you're up," the elder sister spoke quietly so as to not wake her teammate. "Yup. Come over here, I want your boobs," the mistress had no such inclinations. The fiery fighter had to steel herself for a moment before saying, "No can do, sis. We've got better things to do." It's been years since she denied me anything. Ruby sat up with a look of annoyance on her face. "What did you just say, Yang?" Yang held a facade of carelessness as she went to her dresser. "Now now, I just thought you might wanna try something different today." She's planning something, but any plan that gets in the way of my morning blowjob is not worth my time. Ruby rose to her feet. "Apparently, you need a reminder on who's the Mistress around here." Yang finished putting on her outfit and turned to face her little sister. "And apparently you're a dumb slut who only thinks with her dick!" Before the shock of what she just said sunk in, the blonde beauty sprinted out of the room. Fucking! Ruby half-sighed and half-growled. It's too early for this.

Most of the school was asleep as Yang tore down the halls. She looked behind her to see a quickly approaching red blur. "Come on Wooby, can't you go any faster!" At the use of a childhood nickname, the crimson storm behind her accelerated even further. Thankfully, the taunting sister had arrived at her destination; she quickly threw open the door just as she was tackled to the ground.

Ruby was like a starving predator on top of her sister. "So here-" Yang tried to speak.

"What the fuck did you just say about me? You little bitch!" The incensed leader yelled.

"Ruby calm d-"

"I'll have you know I graduated top of my class at Signal."

"You were the only one in your class."

"Shut up!"

"I'm sorry, alright! I just wanted to get you here so I riled you up a bit." A bit?!

"That's a terrible idea…" Ruby calmed herself down.

"I know, I know. It was the only way I could think of." Well, at least I won't have to correct you, still want that blowie though.

"Alright, where are we then?" Ruby looked at the room they were in. "Is this the-"

"Gym! Yes! You don't even recognize it, do you?" Yang exclaimed. Oh. I see where this is going.

"Well of course I didn't. I've never been here." The younger sister replied defensively.

"And you don't see a problem with that?"

"No. Why would I need a bunch of weights and grunty boys to stay in shape? That's what the grimm and you guys are for." Yang gave her sister a look. "I mean sure maybe I could be a bit stronger but I don't-" Ruby found herself rising from the ground as her sister stood, unhindered by the young girl clinging to her. Okay, so she may have a point.

"Ruby," Yang said seriously, "you need to be stronger, as a huntress, a leader, a Mistress, and my baby sister. I don't want what happened with Peach to happen again." Ohh that makes more sense.

"Weiss told you?!"

"Nah, me and Blake didn't actually leave, just stood behind the door." Ah. "Please, let me train you." Well damn sis, I'm gonna cry.

"Fine, since you went through all this trouble. I'll do it." Ruby resigned.

"Great! Follow me." I'm going to regret this. Aren't I?

Yang produced a set of gym clothes from somewhere on her person. "Here, you can't work out in your pajamas, right?" After a quick trip to the changing room, the sisters stood in matching, color-coded outfits. "Just a sports bra, shorts, and some spats, huh?" Kinda breezy. "You gotta let your body breathe, ya know. Plus, it's fun to watch the boys drool." Ruby hadn't noticed before but they were attracting more than a few looks from the handful of people at the gym this early. Hmph. The drowsy girl crossed her arms. "Anyways," Yang continued, "let's start with some stretches." The older girl led her leader through some basic stretches. "Alright, let's go ahead and get the cardio out of the way now." "Cardi-wha?" "Don't worry about it… Just get on this treadmill." Okay, this is just running. I can do that. Ruby ran on the machine for a while. An increasingly larger zone of musk formed around her as she started to sweat. Nobody looked at the two huntresses anymore and they gave them a healthy amount of space. Yang didn't mind the smell, in fact, little tents could be seen on her bra. "Okay, good job!" She gave her mistress a longer hug than necessary. "How ya feelin?" Like shit. Thanks for asking. "My legs hurt…" Ruby complained. "Great! We're doing arms now anyways!" Great…

The gym was still mostly empty as Ruby struggled to push the bar up. My arms feel like they're going to fall off. "H-how many more?" "Just 29. This set." I can't do this! Ruby wheezed as she slowly lowered the weights back down, only to have to raise them again right after. "How long h-have we been going?" "Forget about that, we've got all day." This is it. I knew my wicked ways would come back to bite me eventually. "I can't do this anymore Yang!" The older girl stepped around in front of her sister. "Look here's your motivation," she leaned forward, giving her trainee an eyeful of boobage. "Stick with me until the end and you'll get something special. Okay?" Ugh. I'm gonna fuck those slutbags real good. As soon as I can move after this. Despite her protests, Ruby did have a much easier time finishing that set, and the one after. Stupid sexy sister! I'll show her!

"Alright! Now we're doing curls. I'm sure even you can handle these on your own. I need to work out too, so I'll be stretching while you give me 200 of those." 200 hundred?! She knows I need my arms after this right?! "Okay…" Ruby plopped down on a nearby bench, a dumbbell in each hand. "Oh, you don't need two. Only do one arm at a time." Well why didn't you say that? "Whatever." The immature leader started curling the weight. I can already feel my arm begging me to stop. I'm sorry, tell it to Yang. What is she doing anyway? She returned to the world to find her big sister's big ass as she reached down to touch her toes. Butt… Fuck, those shorts are so tight! I bet if I just stuck it in they would stretch around my cock like a condom. Yang smiled to herself when she saw she had her sister's attention, and erection. She slowly unfolded herself before lowering herself to the ground. Legs spread wide, she leaned over and grabbed her foot. The result was a nice full body stretch and put her legs and ass on full display. Yeah spread your legs slut. Yang stood again and faced her sister. "That should be enough for that arm, sis. Weren't you keeping count, or were you distracted by something." should stick my- Oh shit, what was I doing? "Ha, that's just because this one was so easy." "Great, then why don't you do 250 on the other arm?" Me and my dumbass mouth. Ruby started on her left arm as she watched her bountiful trainer stretch her arms and torso. Side to side. Big boobies go side to side. Wanna kiss em, lick em, put em in my mouth. The straining futanari's shorts were having trouble staying dry and in one piece. "Okay sis, I think that'll do for curls. Ruby! Put the weight down!" spray cum all over- huh? See Yang, this is what happens when I don't get my morning blowjob. "So are we done yet? I don't think I can take much more of this." "Not yet, come over here." My legs hurt. My arms hurt. My dick is about to explode. When will this nightmare be over?!

Yang sat Ruby down at a funny-looking machine with a dangling upside-down u-shaped handle with two grips on the end. "Is this one for exercise or just torture?" The older girl ignored her. "Okay, just put your hands on the grips. Yeah, like that and let me." She jingled around with something behind the machine. "Okay now just pull it down. Great! Give me 20 of those to start." That's not too bad… now what is she doing? The athletic huntress was carrying a barbell with a ridiculous number of weights on it. "T-that's not for me right?" "Of course not I said I needed to work out too didn't I." Oh, thank fuck. Ruby watched as her sister hoisted the bar onto her shoulders and slowly squatted down. She really is a muscle brain. Oh wow! Her ass is enormous like that. I should ask her to do that on my face sometime… Ruby continued to fantasize about fat bimbo asses until her set was complete. "Uh, Yang? I finished." "Yeah? Then give me four more sets and we'll call it good." Four! Did my kind, loving sister get swapped with a demon while I wasn't looking? At least she kept her fat yams. However, the young leader did manage those four sets, all the while studying every curve and muscle on her sister's rear end. Finally.

"So we're done now, right? Cause I've got a date with a certain blondie in about five minutes." Yang set her weight back on the floor, having worked up a sweat herself. "Well, that'll just have to wait for one more thing." "But you said-" "blah blah blah I know what I said. Just lay down on the bench over there, it'll be real quick." Ruby, haltingly, drooped herself over it, facing the ceiling. You know, being a baker is looking real nice right about now. "Okay, so all I need you to do," the domineering trainer dropped the weight she was just using into place over her sister's head "is lift this once." Well mom I'll see you soon. "You can't be serious." "You can do it. Just breathe, focus your aura, and pick it up." Well, when you say it like that… "It didn't work. Yang, this is stupid. Even if I managed to move the stupid thing I'm just gonna wind up dropping it on my throat or something." "I thought you'd say something like that which is why," Yang sat down on her sister so that her baby sister's dick was just touching her butt. "I'll be here to make sure you're safe." Hnng Please don't make me cum my shorts in public Yang! "Focus on your arms, channel everything you're feeling into them." Okay, now my arms are blue balled too. What's your point? "C'mon you're not even trying." Yes I am! I'm just not strong enough! Ruby shook as the weights ignored her efforts. "Hmph. Maybe I should tell Oz I should be the leader since you clearly aren't cutting it." Being a bitch isn't helping! But the bar did wiggle, just a little, as Yang watched. "What's that? Hold on sis some really cute guys are calling me. You just wait here okay?" There's no waBUT She's still pissing me off. Fucking cocktease! "Maybe I'll go straddle them instead." Yang smiled smugly at her mistress, heavy tits dripping with sweat. No! You're my sister! My slut! My tits! My ass! My slave! YOU ARE "MINE!" The other patrons were a little startled at the sudden outburst but Yang waved them off. Meanwhile, Ruby stared at her outstretched arms in a daze. What did? I lifted it? I LIF- OH SHIT! Yang easily caught the weight and reracked it, inadvertently smothering her little sister in the process. She then continued to smash her sweaty tits into her trainee's face as she squeezed her in a bear hug. "I'm so proud of you!" Ah, this is nice. Ruby mumbled something that was forever lost to the slippery prison she was in. "Oh shit. Here let me get off you." Yang stood as her exhausted leader breathed heavily. "Congratulations Ruby, you've completed your first day of Yang's Super Huntress Improvement Program. How do ya feel?" First day? "Like… shit…" "Well, I know what'll perk you up. Follow me." The older girl walked away, swaying her hips as she went. Ruby watched as her body was pulled along after that ass by her still-raging dick. That better have been worth it.

Yang led the younger girl into the locker room. "Oh good this place is empty, I thought we'd have to get into a closet or something." "So what's this 'something special' you promised?" "You'll see, just hold still. You don't need to do a thing." She started by slowly taking off her clothes piece by piece, letting her sister get a good view as her enormous tits bounced free and her moist pussy was revealed. Fuck I need this so bad! Yang playfully batted her mistress's hands away from her inviting body before peeling her sister's soaked bra and shorts off. The horny futa's cock was glistening with sweat and precum. Yang reached down into her shoe and produced a roll of condoms. "So you don't make a mess." Whatever just hurry up! After the drooling phallus was properly sheltered, she started to slowly, methodically stroke up and down that giant monster using only her hands. What is she doing? That's not enough! The eager girl started to buck her hips but the other girl simply loosened her grip until she was humping nothing but air. "Sorry sis but I need you to stay still or this won't work." This is bullshit! "No! Yang, as your Mistress I order you to make me cum right now!" "Are you sure?" "Yes!" "Okay…" Yang immediately started stroking as hard and fast as possible. Oh fucking shit wait fuck I'm gonna! Yang has had a long and intimate relationship with her baby sister's cock so she knew when she was about to cum. She used this knowledge to bring Ruby right to the edge before suddenly letting go of her shaft completely. Nooooo why did she stop? I was gonna… cum? I'm cumming?! With the lightest of flicks, the baby batter stuck in the frustrated futa's nuts came pouring out. I'm cumming… but I'm not cumming?

"You look confused." Yang had a smug smile as she explained. "It's something Blake told me about. This whole thing was her idea actually. Apparently, orgasm and ejaculation are two connected but separate things. So, you can make someone orgasm without them cumming or, like now, you can cum without the good part. Kinda like how you can sometimes cum with your pussy even after your sack runs out."

Okay but "Why. The Fuck. Would I ever want that?" Ruby pouted.

"I figured you wouldn't like it, but I'm gonna have to keep going anyway."

"Nononono fuck th-"

Yang quickly stuck her lips onto Ruby's and started pumping her cock again. No it's too soon! Ah! That hurts! Fuck I'm gonna cum! The denied girl thrust futilely against the air as her orgasm was ruined once again. In one swift motion, Yang slipped the nearly bursting condom off her mistress's dick and slipped it into the tired girl's mouth. "Drink up, it's good protein." With no other choice, Ruby let all her own sperm slide down her throat. Why? I just want to cumm! "I know this seems harsh but I promise that we have your best interests at heart." Then let me cum pleease! After her sister drained the first condom, Yang put on the next. "Blake says that she needs you as horny as possible for tomorrow so I can't let you cum for real until then. But, I know you're a growing girl with needs so I'll be sure to help you fill up every single one of these condoms before we go back to our room." no please I cant take this…

True to her word, Yang drained every last bit of cum from her sister and then fed it right back to her, with the odd treat for herself. Anytime Ruby tried to say anything beyond begging and babbling Yang would fill her mouth with her tongue, or her boobs, or one of the used cum balloons. After a while, it became harder for her to cum so the older huntress started playing with the rest of her body as well. She tweaked and sucked on her nipples, kneaded her cute booty, shoved fingers up her tight pussy then asshole, and she licked her sister head to toe savoring every drop of sweat on her. She, of course, paid special attention to her hairy armpits which never failed to make both of them come. And, through it all, Ruby didn't get a hint of release.

pleasepleasecummecumplease Ruby's sense of self had largely devolved to her angry, dripping, throbbing fuckstick and her other major erogenous zones. "Come on, Ruby let's get you cleaned up." Still, she responded to her sister's words. cum!yespleaseletmeidocumplease Seeing that she was in no condition to get up herself, Yang picked up her baby sister, causing the broken girl to shudder as her body attempted to shoot out what just wasn't there. The older sister carried her to the still empty showers where she promptly turned on the cold water. coldcoldcoldcummimgcold Dutifully, the slave washed herself and her insensate mistress.

Slowly, as if still holding out hope for a proper nut, Ruby's abused member finally went down under the harsh, cold rain. cold… and wet "wanna cum…" The mistress mumbled.

"I'm surprised you can still speak after all that, sis." Yang teased. yang…

Now that her brain had more blood to work with, Ruby started to come back to herself. "What the hell happened?"

"I milked you." What?

"So, how do you feel? Are you still horny?" Yes! No? I know that I want to fuck but I also don't want to fuck? Ruby stared at her sister's wet naked body. I would love to smash you into next week but… "Yes and no, right? That's what she said would happen. You'll start filling those tanks soon enough though we'll probably need to take at least one more shower. But other than that I think you're ready for tomorrow."

"Tomorrow?"

"For Blake's turn!"
