Hello readers, I am going to start a small series here that may be updated every once in a while. Please leave a constructive review.

Chapter 1: (Ruby x Glynda x Yang)

(Futa, Yuri, Slight incest, Threesome)

"Ugghhhh"

"Jeez, it's so hot..."

"When will they fix the AC?"

It was summer at Beacon, and everyone was complaining. Even Weiss, who totally never ever complains about anything, ever. Especially the AC.

"Hey, Ruby," Yang said to her younger sister.

"Hey Yang, enjoying the heat?"

"Yeah, I sure am. I just wish ice bi- I mean Weiss would be quiet for once," Yang replied, "maybe we could take a walk or somethin' until she shuts up, maybe to the beach or something."

"Alright Yang, maybe we could go to the beach and swim."

"Sure, Rubes. I'll go get my swimsuit on."

Yang and Ruby got their swimsuits on.

Ruby couldn't help but occasionally glance at her sister's breasts. They were just so big and her swimsuit was just SO tight.

Ruby walked hand in hand to the beach where they laid out towels and laid down on the beach. Ruby noticed Glynda on the sand across from them

"Hey Yang, there's Glynda over there. Do you wanna say hi to her?"

"Sure, Rubes."

Ruby and Yang walked over to where Glynda was. Glynda was wearing a really, really tight and small bathing suit.

"Oh no. Don't do it. Don't. Please don't." Ruby thought to herself, trying to not get an erection. "Everyone's gonna know with your swimsuit on. Please don't."

Ruby looked over at Glynda in that skimpy swimsuit. She could see just a little of her nipple poking up. That had pushed Ruby over the line. She felt her penis growing slowly in her swimsuit as it tightened even more and more around her.

Yang finally broke Ruby out of her thoughts.

"Hey, Glynda, my grade could use some improvement. Is there anything that I could do to boost my grade some?" Yang asked.

"Hm. I'll think about it. Meet me in my classroom in 5 minutes" Glynda replied.

"Alright Ruby, let's go there. I think the classrooms have A/C."

Ruby sighed in relief. Finally they could get away from everyone so nobody would see her still growing erection. Ruby and Yang gathered up their towels, and headed to the classroom still in their bikinis.

Glynda was sitting at her desk, sorting papers. She was still in that revealing swimsuit that Ruby loved so much. Ruby and Yang walked up to her.

"Hi Mrs. Goodwytch!"

Glynda looked up at them.

"Yang. I have some work you can work on at your dorm. Ruby. Stay here. I need to tutor you privately."

Yang took her papers and walked out the door, while Ruby stayed there, wondering what Glynda would make her do. Glynda pulled up a chair to her desk. Ruby kept taking peeks at those succulent breasts of hers.

"Ruby, sit down. We need to talk about something."

"Yes, ma'am?"

"I always see you masturbating in class. You always do it in the back of the room. I've seen it on the cameras."

Ruby blushed so much, she was almost the same color as the red bathing suit she was wearing. Why did this somehow turn her on? Something about that turned her on.

"I-I'm really sorry about that, ma'am."

"No, Ruby. I really enjoy it. I want you to do that more. Ruby. I want you to do something."

"Y-Yes ma'am?" Ruby said, shocked about this entire situation.

"You want some extra credit?"

"Yes, ma'am."

Glynda took off the top of her bikini, revealing those juicy boobs that Ruby had been obsessed with for a while. Ruby's dick instantly grew harder and harder.

"Ruby. Take off your bottom. Now."

Ruby obeyed and her throbbing 14-inch dick came out.

Glynda took off her bottom as well, showing off her vagina to the younger girl. This made Ruby happy to finally see the teacher naked. She had rubbed herself to her in class all the time.

"Ruby..."

Glynda walked over to Ruby, while Ruby, too scared to move, only sat there watching the headmaster get closer and closer to the erection.

Glynda put the tip of Ruby's throbbing cock in her mouth, teasingly.

Ruby let out a gasp as pleasure filled her body.

Glynda licked the tip, putting her tongue slightly in the slit of her penis.

Ruby let out a shrill moan.

Glynda put more in her mouth, and started to lick the still-growing penis. Ruby released some precum into her teacher's mouth. Glynda tasted it and started to lick faster, getting Ruby harder and harder as she put more into her mouth.

Glynda tugged her mouth off of Ruby's dick. Ruby let out yet another moan, as the teasing had turned her on.

Suddenly, Yang walked back in the door, not noticing that her sister and her teacher were fully naked.

"Hey guys, I got my homework done. Where do I turn it i-" Yang cut off herself when she saw the sight.

"Oh, so this is going on." Yang added.

Glynda giggled teasingly as she motioned for Yang to come over to her. Yang obeyed, and when she got to her destination Glynda began to grope Yang, finding that she had a dick like Ruby. She tugged down her miniskirt, exposing her slowly-rising dick.

Yang's dick was about 18 inches long when it was fully hard, and Glynda seemed to get even more turned on by this fact.

Glynda sat on a desk with her legs in the air.

Ruby sat on top of Glynda and inserted her dick into her pussy, eliciting a loud moan from Glynda and Ruby simultaneously. Ruby thrusted a bit into Glynda.

Yang inserted her entire dick into Glynda's ass, making Glynda make a noise of both pleasure and pain. As the two sisters kept penetrating their teacher deeper and deeper, Yang had an idea to add to the fun. Yang grabbed Ruby's developing breasts and squeezed them.

Ruby took pleasure from this. "Y-Yang! G-Glynda?" Ruby swallowed. "I-I think I'm gonna let cum out now, Yangy."

"Alright, Ruby. You can do it. Let out your juice." Yang comforted Ruby.

Ruby came in Glynda's pussy, at the same time Yang did.

"Good job Ruby. Glynda. You wanna do this again next weekend?" Yang said.

"Sure. Take Ruby back to your dorm so nobody catches us."

Yang dressed Ruby and carried her back to the dorm, and laid her down to sleep.

Alright guys, that's the end! I will definitely update this eventually.
