Chapter 1

Hey everyone this is my first time writing a M-rated story and my first time writing an age regression fanfic. A friend of mine from school asked me to write this for them. I would like to ask for you all to leave reviews with your opinions of it. I hope you enjoy the story also no hate reviews if you hate age regression.

It was an ordinary day at Beacon team RWBY and team JNPR were relaxing an eating lunch when Ozpin called Yang and Blake into his office. The two made their way to the office Blake was calm while Yang was nervous. Once they got their they saw Ozpin drinking his coffee while looking at his scroll.

"Hello and Long do you know why I called you here" he said calmly.

"You can't prove it was me who put the fireworks in the boys bathroom" Yang blurted out.

"Well I called you for a different reason but it is good to know who was responsible for that incident" he said

"If you don't mind me asking sir why did you call us here?" Blake asked.

"I have a mission for you two and the mission is to spy on the White Fang" Ozpin said.

"But sir we have no idea where the White Fang are" Yang said.

"We have reason to believe that the White Fang are hiding in a abandoned warehouse outside the walls of Vale" he said.

"Ok sir we will go prepare and leave if that is all" Blake said.

"Yes that is all you can inform your teammates of your mission but no one else and if anything goes wrong call them and I will have a airship has fast has possible" he said.

"Understood sir we will go prepare" Yang said.

With that Blake and Yang left to go to their room to prepare. When they got their the saw Ruby doing her homework and Weiss standing over Ruby making her do her homework. When Ruby saw the two she gave them a pleading look to help her. Yang wanted to help but she also wanted to laugh at her sisters torment. Blake walked over to her dresser and got hers and Yangs clothes for the mission while Yang explained the mission to Ruby and Weiss.

"I am not sure about this I think Ozpin should send us all and not just you two" Weiss said.

"I have to agree with Weiss besides stealth is not exactly your strongest skill" Ruby said.

"Come on guys me and Blake can handle it besides Ozpin said if we need help we call you guys and he will have you guys dropped off at the warehouse" Yang said has she finished changing clothes.

"Well make sure to call right when something goes wrong" Ruby said.

"We will and don't worry I will keep Yang from blowing our cover" Blake said has she loaded some dust rounds into Gambol Shroud.

"Ok good luck and be careful" Ruby said hugging Yang.

"Thanks sis and don't worry we will be back soon" Yang said. With that Blake and Yang left to the airship that would drop them off.

*A 2 hour flight later*

Blake and Yang jumped from the airship and landed on the ground and looked around but saw no one. The quickly made their way to the warehouse and saw no guards. Blake motioned for Yang to follow her has they climbed to the roof and dropped inside landing on a catwalk but saw nothing out of the ordinary inside the building. Blake and Yang began to look around trying to find a clue when all of a sudden gas started spewing into the room. Yang and Blake covered their mouths but then someone attacked them. Their attacker punched them both in the gut causing them to fall to the ground. Unfortunately they inhaled some of the knock out gas causing them to pass out.

*An hour later in an underground base*

Blake and Yang slowly began to open their eyes when they realized they were tied up. Blake began to reach for her scroll in her back pocket and was surprised it was not their. Before she could ask Yang if she had her scroll the door began to open. In walked a old man with grey hair, a lab coat, black pants and house shoes. On his head was a pair of brown bear ears.

"Hello it looks like these grunts caught some good prey" the guy in the lab coat said.

"Let us go you son of a bitch" Yang yelled.

"Now now no need to get violent we just need you for an experiment you see this base is obsolete but I have one last test to run and you two are my test subjects" he said with an evil gleam in his eyes.

"You sick son of a bitch" Yang said.

"Now then bring in the supplies" he said has a grunt walked in with a pill, a glass of water and a needle.

"Now then the blonde goes first" the scientist said.

Yang began to struggle trying to break free from her restraints. The grunt approached her and forced the pill into her mouth and proceeded to pour the water down her throat. Before she could spit it out the grunt covered her mouth and pushed her head back causing her to swallow the pill. After the grunt removed his hand from Yangs mouth she began to cough violently trying to break free. What the grunt didn't realize the chain holding Yang was starting to break.

"Ok now for the traitor but first the shot must be injected into her clitoris so strip her" the scientist said.

Blake began to struggle and tried to kick the grunt back but the grunt was fast enough to catch her leg. He grabbed her shirt and pushed her into the wall ripping her shirt and bra off. Her breast bounced has her nipples became hard because of the cold air in the room. The grunt then grabbed her pants and ripped them off leaving her in her black lacy panties. The grunt ripped them off leaving her naked. The grunt grabbed the needle and injected it into her clitoris. Blake screamed in pain and then Yang snapped. Yang snapped the chain and kicked the grunt before she dashed and slammed the scientist into the wall knocking them both out. Yang took the keys from the scientist body and released Blake from her restraints. Blake then removed the cuffs from Yang and both began to run looking for their scrolls and weapons.

After running for a few minutes an alarm went off surprising them. Blake and Yang saw at least 20 grunts while running. Blake found a room with only a single grunt in it. After she knocked it out she found their scrolls and their weapons. Yang grabbed her weapons but for some reason they slipped right off. Blake sent a message to Weiss, Ruby and Ozpin asking for backup. Blake turned to Yang and noticed that Yang seemed to be shrinking.

"Yang what happened?" Blake asked surprised to see Yang who looked like she was 13 years old now.

"I don't know but we don't have time lets go" Yang said before turning around and face planting.

"It looks like your clothes are getting too big for you" Blake said picking Yang up.

"Great just great" Yang said annoyed.

They all of a sudden heard the grunt groan and has she began to regain consciousness. Blake picked up Yang and began to run. Has they ran Yang seemed to be getting younger and younger for some reason. Has Yang began to slowly turn back into a child her clothes began to fall off. Yang took off her shirt and bra and threw them to the ground to avoid leaving a trail for the grunts. After a while Blake ran into a storage room and looked at Yang only to see a baby. Blake sat down trying to catch her breath when all of a sudden she felt like her skin was on fire she set Yang down when she felt a tingling sensation from between her legs. All of a sudden a umbilical cord came out of Blake's pussy and attached to Yangs belly button. All of a sudden Blake saw Yang was being dragged to her and she felt Yang slowly begin to enter her. Blake bit her hand to stop herself from screaming in pain. Once Yang was fully inside Blake she felt her stomach shrink and stop. Blake looked and saw her stomach was bigger then normal.

All of a sudden the base began to shake. Blake prayed that it was Ruby and Weiss and not explosives in an attempt to kill her. All of a sudden Ruby and Weiss busted into the room and were shocked to see Blake naked and with a big stomach.

"Blake what happened and where's Yang?" Ruby asked.

Blake explained what happened until they showed up. Weiss and Ruby looked at her in surprise not sure how to react. Weiss wrapped a towel around Blake and helped her and led her back to the airship. The medical team put Blake on a stretcher and began to run some test. Ruby prayed that their was a way to undo the drugs has she and Weiss got back on the airship and left for Beacon.
