A/N: Hey fans! I see you must have liked the first two chapters. I was originally planning on having Yang fuck every character, but I'm not sure yet. This chapter is a foursome of team RWBY. Have fun!

Chapter 3: girls just wanna have fun

While Blake and Weiss were studying in the library, Yang went back to the dorm. She heard Ruby singing in the shower, so she waited for her to get out. A few minutes later, Ruby walked out wrapped in a towel. As Ruby walked over to her bed, Yang jumped out and ripped her towel off.

"Ahh! Yang, what are you doing!?" Ruby shrieked, trying to cover herself.

Yang grabbed Ruby's arms and pulled them away from her breasts and forced her onto Weiss's bed.

"Yang! What are you doing?!" Ruby yelled.

"Just havin' some fun with my little sis!" Yang replied as she pushed two fingers into her sister's wet clit.

"YAAANNG!" Ruby shouted as Yang rapidly moved her fingers in and out of her sister. Yang pulled her skirt down, her rock hard 14" cock popping up. She stood up, and pulled Ruby into a sitting position. She forced her cock into her sister's open mouth. Ruby gagged on her sister's cock as it rapidly dipped into her throat repeatedly. Yang pulled Ruby off her dick and pushed her back onto the bed. She flipped her over onto her belly. She held Ruby by the hips as she pushed her cock into her virgin sister's asshole.

"AAHHH! YAAANNNG!" Ruby yelled as Yang's cock pushed deep into her ass.

Yang was busy pounding her sister's ass, she heard the door open and then heard gasps. She turned to see Weiss and Blake.

Yang pulled out of Ruby, and she collapsed on the bed. Yang turned to face her teammates.

"What about you and me this morning, Yang?" Blake asked.

"What about you and I at lunch?" Weiss asked.

"Wait, she fucked you?" Blake asked Weiss.

"She fucked you?" Weiss replied

"You're fucking her?!" Blake and Weiss yelled simultaneously, pointing to Ruby.

"Ladies, ladies, we can all have fun here!" Yang said, smiling nervously.

~cool transition~

Yang and Ruby laid on the bed in a 69 position, Yang's face buried between her sister's legs while Ruby was taking all of Yang into her throat. Blake and Weiss stood at Yang's rear end, wearing strap-ons. Blake was fucking Yang vaginally while Weiss got her anally. Blake and Weiss were making out with each other as they fucked the blonde. Yang had also put vibrating buttplugs in the three girls' asses.

Ruby moaned as Yang's tongue worked her pussy, the vibrations in Ruby's throat making her even harder. As Yang neared her climax, she put her hand on the back of Ruby's head, pushing her further onto her cock. She came, her anus and pussy clenched tightly around the dildos as she shot her massive load down her sister's throat. That caused Ruby to cum, squirting into Yang's mouth. Blake and Weiss climaxed just watching them.

Ruby gasped for air after she pulled Yang's cock out of her throat. Blake and Weiss pulled out of Yang as she rolled over onto her back, pulling Ruby on top of her. Ruby sat up so that she was on her knees, with her pussy right on Yang's face. Weiss took off her strap-on and crawled up on the bed. She pulled Ruby down to eat her out. Blake pulled out Weiss's buttplug and pushed her rubber cock into the open hole.

Sun and Neptune sat on a tree branch outside the dorm window.

"Damn! Dude, your girlfriend is a lesbian!" Neptune said.

"Yeah, well, so is yours!" Sun replied angrily.

"Hey, that's fine with me." Neptune stated as they watched the girls.

They watched intently as Ruby orgasmed again, filling her sister's mouth. Weiss came next, filling Ruby's mouth with her juices.

"Hey, why aren't we filming this?" Neptune asked.

"Because they would kill us!" Sun replied.

"Right." Neptune said.

A/N: hey there! I know this chapter is a little short, but I'll make the next one longer, I promise. I hope you liked it. Have a good day. Quek Quek.
