I don't own RWBY. Rooster teeth do. The is just a fan based parody. Mostly a smut parody.

"MMmm. Aah."

These sounds grew louder and louder. The source? Team JNPRs' room. They grew louder until a familiar voiced spoke up.

"Yang, shh! If you get any louder you'll bring attention to us." Juane said as he kept thrusting into her.

'Too late.' She thought to herself. She already eyed Ruby spying through the crack of the door frame. She didn't mind though. In fact she wanted to do something just for her little sister.

Yang pulled Juane closer. Whispering she begged. "I want you to fuck me like a mutt. When you're about to cum..." She had to hold her breath as he hit her G-spot. "Want it in my mouth!" She almost shouted as her orgasm took over.

His response was repositioning her weaken body. She appreciated that. There was no way she could move comfortably. Not after being used as his cock sleeve for the last hour.

"How exactly do you want it?" He lovingly ask.

She tried but failed to turn her head to him. "Ram me like your breaking down a door." She felt his pleasurably massive cock slowly penetrate her.

"And your G-spot?" He ask out of concern.

"Just break me in! Train my pussy to only love your cock!" She was very hungry for this. To be fuck into oblivion. Consumed by ecstasy. To have her sister watch and masturbate.

"Oh, mmgh! fuck!"

She felt her demands in full swing as he impaled her. The force making her lurch forward. She felt his pelvis smash against her ass as he struck her deepest spots. She felt an enjoyable shock when that happened. Feeling his cock ram in and run back to her entrance never leaving. He stayed there just long enough to ram into her again. Striking her G-spot a second time. Then a third time then a fourth and again and again. Her pleasure and excitement was now making it hard for her to breath. She struggled to gasp for air in-between moaning and her pussy getting abused. He wasn't just going in and out of her pussy anymore. It was like he was filling her body before leaving it empty! Starving!

Through all of this she saw Ruby starting to masturbate. She saw Ruby try to stay and watch. But eventually Ruby left. Probably having seen enough.

Her thoughts stop as she struggled to stay conscious. Her orgasms now continuous. Making her fade little by little. She finally gave into the pleasure. Soon after she lost all strength to his assault and fell to the bed.

Juane pick her back up. "Not yet yang. I'm only getting warmed up." Juane said to Yang. Hoping she would stay with him long enough to swallow his cum.

Ruby was angry when she had seen her friend and sister making love. Her anger wasn't about them doing the 'deed'. It was that her sister was the one Juane was loving. She wanted him! She then made a promise that whatever happens that she wasn't going to lose him to her big sister.

The moans her sister made did turn her on. They hadn't noticed her yet. Looking back and forth she saw no one coming through the halls. Might be the break going on and people want to have fun. Looking back she saw her sister smiling right at her!

She was caught! She was going to be in trouble with her sister! What is she going to say? 'Sorry but I wanted to see my sister make love to my best friend?' That won't fly. She had a thousand thoughts race through her head. None were good.

She heard her sister whisper something to Juane. A moment later her sister was on her knees with her butt up and her elbows holding her up on the bed. Juane got on his knees behind her. Then she saw his penis! Now on full display she saw how big it was. It had to be the size of a fully grown cucumber! If not slightly bigger!

Then he slowly pushed in. She saw there was resistance as it bent. Now she got to see how a thing that big could go inside a lady. Which looked painful as her sister seemed to lose her breath.

Ruby started to feel her underwear get wet. Embarrassed she thought. 'Am I getting horny? Just from watching my sister taking. This. Massive. Cock. Oh god it's going all the way in!

She was getting too horny to do nothing. Her hand moving inside her underwear. She began rubbing her clit as she heard her sister yell at Juane.

"Just break me in! Train my pussy to only love your cock!" Yang demanded.

This turned Ruby on even more. She began massaging faster and harder. Not caring if others caught her she went on to squeeze her breast. She moved, pinch and palmed her boob all while playing with her pussy.

She pretended that she was the one getting ramed into by Juane. After a few moments of touching herself she cumed. Not Juane though. He kept ramming Yang. His dick slamming into her. Yang clearly wanting her to watch. Which she did. All the while she touch herself.

Ruby was in her teams room. Pacing as she thought about her sister getting fucked. What she saw couldn't have been love. No, it was fucking. The word sticking as she remembered what it had meant. How it applied to her sister and Juane. She soon thought about if she stayed to watch.

She was getting horny from thinking about her sister getting fucked by Juane. Yangs' breasts swinging and jiggling as she got pounded. Watching her reactions as he stirred her pussy with his massive cock! How she sounded as she cummed.

Ruby finally realized what she was thinking about. She was attracted to her own sister!

She went to her bed. Unable to stop herself from masturbating. She took her underwear off. choosing to keep her skirt on made it more erotic for her. She also took her top off.

She lick her hand until it was soaked. Her other had two fingers inside as she moved them in and out. Her saliva covered hand was playing with her tit. She pretended her wet hand was Yang. Sucking and biting her nipple. Her other hand she imagined was Juane, slowly fucking her!

Ruby then turned to her side and had her hand reaching behind. Pretending that Juane was there. Fucking her from behind. Her other hand rubbing her clit. Wanting Yang to suck on it as Juanes' dick moved in and out.

Ruby continued to think of ways that Yang and Juane would take her. Fuck her. She lost track of time and reason. All she wanted was them. No matter how many times she cummed it was still not enough. She needed them to take her.

She finally stop after Oum Knows how long. Her breasts moving as she tried to catch her breath. 'I need to get one of those dildos.' She thought as her exhaustion took her. Forcing her to fall asleep.

Hope ya enjoyed. Going to do some one shots. Let you know when a chapter is a sequel or stand alone.
