Chapter 4: Suu

It was a rainy day at the Tower. Beast Boy and Cyborg were playing a racing game as Mia is at the kitchen cooking, Centorea polishing her fake sword, and Rachnera is relaxing on her own web reading a clothing magazine. Starfire is at the gym doing some work out so she'll be busy.

"Grass Stain, what is Mia cooking in my oven?" Cyborg asked his best friend.

"Its best if you find out." Beast Boy replied in nervousness.

"Honestly, you boys go play your games while letting Mia cook. Master Beast Boy, Sir Cyborg, as a fine warrior myself, I should be cooking." Centorea states as she walks to the kitchen.

"Master?" Cyborg questions.

"Its a Centaur thing, noble and stuff." Beast Boy told his friend.

"I can cook fine, Centorea." Mia said as she has no idea what is she's cooking. Because of being a carnivore, she has 1/25 - 2/50 of taste sensitivity than what humans have, meaning she can't tell the difference between bad food or not. "Besides, if I cook, I'll get pointers for my darling's impression of me being his wife." she whispered to the Centaur woman.

Blushing in an obvious sense of jealousy, Centorea shoves Miia away from the cooking pot as she said "If thou are so willing to cook to be the Master's husband, then I shall taste it first." Centoria said as she opens the lid of the pot, as suddenly something gooey appeared from inside the pot as it jumps up from the pot "What in blazes!?" Centorea screamed as well as Miia which gotten the attention by the two Titans.

"Yo, what is that!?" Cyborg asked looking at the slime thing on the ceiling as it crawls towards the door.

"Miia's cooking came to life!" Beast Boy exclaimed baffled by the situation.

"Waaah! I didn't mean to!" Miia screamed in fear as the slime escaped.

"Well, this has been entertaining." Rachnera said watching the chaos happening.

/

Starfire was sweating after running the treadmill. She wants to look good and in shape for crime fighting when Robin's away in Gotham. She was all sweaty from her purple top to her matching gym shorts and tennis shoes.

"My what an exercise." Star said to herself as she uses her towel to wipe the sweat from her forehead. Unknown to her something gooey appeared from the air vents as it slides down on the wall "I'm so sweaty, I should take the shower." Star said placing her towel to wipe the back of her legs.

As Starfire wipes the sweat out of herself, she still feel moist. Then suddenly she felt something wet and sticky touching her bottom from where she sits surprising her.

"Eep!" Starfire shrieks as she looks down expecting Silkie, but instead...

/

"WWAAAAAAAAAAHHHHH!" Shout a scream which caught the Titans by surprised as well as the extraspecies girls.

"Starfire!" Beast Boy and Cyborg shout at the same time.

"Lady Starfire is in peril!" Centorea exclaimed as she prepares her fake sword ready.

"Sounds trouble." Rachnera said as she stood up. "Lets go check her out."

"You two stay put, me and BB will check it out." Cyborg said as he forms his arm into an arm cannon.

The Titans rushed to their friend''s location in the gym and gasped at what they saw. Starfire was lying on the floor with her finger in between her teeth as she stifled a moan as a blue glop thing covered her barely covered pelvic area.

"Mmmmm." Starfire moaned as she tried to remove the offensive goo from her body, but it felt too good for her to think.

"Starfire!?" Beast Boy yelped in shock and he felt the blood flowing down south.

"F-Frrriends?" Starfire replied as her eyes opened to see her friends and she screamed in shock. "This isn't what you think it is!" She ripped the goo off of her and threw it to the other side of the room.

"What is that?" Cyborg pointed to the goo that started to move and changed into a naked goo girl with three tendrils as her hair. "Beast Boy... not again."

"I swear I don't know this one!" Beast Boy objected.

"Master, we are here to save Lady...Starfire." Centorea said as she, Miia, and Rachnera saw the naked blue slime girl as she turns her head towards them. "What tis that?"

"Could be another extraspecies girl." Cyborg said as the slime girl just looks at the others as she sees the hand movements they're making as she cross her arms like Cyborg did.

"What is she doing?" Miia asked as she looks at Starfire. "What happen to you, Star?"

"Nothing! That whatever she is, was doing something all over my Grebnacks!" Starfire said in embarrassment as she waves her arms around like waving noodles.

"Greb...nacks." the blue girl repeats what Star said.

Suddenly, the blue girl looks at the sweat beads from Miia as she slime girl charge towards the Lamia girl as it covers her slimy body all over the Lamia.

"AAH! She's gotten me!" Miia screams as she moans when as the slime girl's head gets all over her body as its slimy tendrils reach for her breast. "Wait, not there!"

"Alright, unhand Miia you...slimy, thing!" Centorea demands as she puts on her stance as all saw the slime girl exit out of Miia after being startled by Centorea's yelling. "She's escaping!"

"Quick, don't let her get away!" Miia said as she noticed that her shirt was pulled up showing her goods. "AHH LOOK AT ME!" she cried out as she swings her tail towards Beast Boy.

'Why me!?' Beast Boy shouts in his mind after being hit by Miia's tail.

"Come on, we gotta find the slime!" Cyborg shouts.

"Leave it too me!" Rachnera said as she crawls up on the roof using her spider legs chasing the slime girl.

/

"Where are you?" Rachnera calls out through the hall way as she looks around the slime girl. She then hears something crawling as she turns around and saw nothing. 'I'm sweating from nervousness. No, I'm not afraid of something whatever she is.'

"Who is there?" The woman was irritated at the goo girl causing a ruckus in her new home. Suddenly coming out of the door of the hallway a burst of soapy water spread towards her as the Arachnee slides down the hallway as she is met with the changeling.

"Rachnee, are you okay?" he asked as the Rachnera spits out the water.

"The washer at the laundry room malfunctioned." Rachnera states as she stands up, wet all over.

It was then the two heard something and it came from the lobby.

"What was that?!" Beast Boy asked in fright.

"C'mon, let's go see what it is." Rachnera said despite being wet she crawled down to where the lobby is.

/

Raven stumbled in soaking wet from the heavy rain outside and sneezed. "Damn it, Argent! Why did you mess up my spell?"

The demoness then heard a weird noise come from behind her. "What? Who's there?"

Nobody answered.

"Hello?" Raven repeated.

"Grebnacks..." A voice came from the dark.

"Starfire? Is that you?" Raven deadpanned in confusion. "What is going on?"

Nothing happened for several seconds before a something slimy wrapped itself around her breasts and nether regions.

/

Beast Boy and Rachnera were walking down the halls as they suddenly heard a different scream.

"AAAAAAAAAHHHH!" A loud scream came from the bottom floor.

"Raven!" Beast Boy screamed in shock.

"Who?" Rachnera asked him.

"She must've came back from her trip. We gotta hurry to the lobby!" Beast Boy said as he change into a bird as Rachnera follows him.

'Gotta get myself dried off.' Rachnera said as she follows the changeling.

/

Raven stood in the floor as she is bound in slime massaging her breast followed by the slime in her pelvic region as it digs itself under her leotard as the empath felt hot from the touch as she moans.

'What's a slime doing here in the tower? If Beast Boy came in my room reading my books again...' Raven thought as she couldn't help but unleash a moan hears footsteps as to her surprise it was Beast Boy, along with a spider-woman. 'A drider? What's he doing with a drider.'

"There's the slime!" Rachnera shouts as the slime looks at Rachnera's wet body as her top is see through.

The slime girl gets off of Raven after sucking out the moister off of her as the slime girl jumps onto Rachnera.

"Gah!" Rachnera screams as she is bound by the slime's tentacles as it covers all over her. "This is…noooot goooood!" she moans in pleasure.

"Beast Boy, what the hell's going on!?" Raven demands as she covers herself in her cloak.

"Um, funny story, but right now we need to save Rachnera from the slime girl!" Beast Boy said making Raven confused by his declaration.

'I've been gone for week and a half and already strange things happened and I know Beast Boy is to blame.' Raven thought as she questions if staying with Argent longer is for the better.

"Get...her...oooooooooooffff." Rachnera moans as she felt her large breast getting sucked by the slime's mouth as the goo girl change into a womanly shape similar to Rachnera. Her slimy hands reach for under the loincloth as Rachnera's legs shake. 'I will...not...submit...to this!' She thought as the slime girl gets off of Rachnera as the Arachne falls down panting.

"Azarath...Metrion...Zinthos." The goo girl mimics as she waves her arms around like if she's performing a spell.

"Darling!" Shout Mia as she and Centorea barge in the lobby with Cyborg and Starfire catching up with them. Mia grabs Beast Boy as she embrace him. "Are you okay? When you ran off to look for Rachnee, I was worried that you might get hurt!"

"Its Okay, I found Rachnera and met up with Raven." Beast Boy said Rachnera looks around.

"Oh man, the slime girl escaped!" Rachnera shouts as the goo girl is no where to be found.

"Can someone please tell me whats going on!?" Raven shouts angrily as a lightbulb went out. "Who are you people!?"

/

One explanation to Raven later...

"So let me get the straight." Raven was pinching the bridge of her nose. "Beast Boy accidentally signed up as a volunteer for an extra-species exchange program and now we have a Lamia, Centaur, and Drider living in the tower."

"Arachne is the preferred term." Rachnera said crossing her arms.

"In my defense, I thought it was for some Japanese manga." Beast Boy said nervously.

'Well at least Beast Boy's interspecies polygamy is much more freaking out than revealing my homosexuality.' Raven thought as she's a bit irritated of the situation.

"So what's a slime girl doing in the tower?" Cyborg asked. "Do you girls know anything about a slime girl."

"No, not much." Centorea states which shocks everyone. "Even we think slimes are a myth."

"So what should we do is figure out what she really is, maybe Ms. Smith knows!" Beast Boy was about to pick up his cellphone, but Centorea stops him.

"Let us not tell Ms. Smith until we are sure its an extra-species or not." Centorea said to him.

"I've read about slimes before. According to myth, they supposed to absorb moist areas and what we need to track her is something or someone wet." Raven raise hand saying "Not it."

"Not it!" The Titans and the extraspecies girls raise their hand up saying not it in unison except for Centorea.

"What! Why me?" Centorea whined.

"Because you're the only one who isn't moist. That, and putting water onto Cyborg would short circuit him." Beast Boy states.

"You're pretty not startled by our appearance, are you?" Rachnera asked the empath.

"Well I am half demon, and have seen a lot of strange things and meet different people." Raven said in deadpanned expression like its another Tuesday for her.

/

Centorea is now at the halls of the tower, where she carries a poll holding two buckets of water like in the old days of China. She nervously waits for the slime girl to appear for the smell of water. Luckily she is given a com-link so she can contact the others.

"Alright, Centorea, you know the plan?" Beast Boy asked the Centaur girl. "Sorry that we have to make you bait."

"Tis is fine, Master." Centorea respond with pride "I volunteered for this in order to capture the creature in the House of Titans."

"Even though we singled you out." Raven said in monotone.

"Well I volunteered anyway." Centorea said without complaint.

Suddenly, she heard a whoosh behind her as the Centaur girl turns around, only to stumble and got her bucket to splash all over her black long skirt as well as her white blouse.

"Curses, I got me wet." Centorea said as she saw the moving object, and turns out to be Silkie. "Oh, its just Lady Starfire's pet silkworm." she said as she calms down as unknown to her the slime is above her from the ceiling.

She felt some ooze on her shoulder as her eyes turn to look up and see the blue goo falling allover. "Master, NOW!" she shrieks as a portal opens as Raven performs a spell.

"Azarath, Metrion, Zinthos!" Raven shouts as the slime stops as its covered in black energy as it forms into a curvy woman with a developed sized chest "Got her, guys!"

"But I'm still wet!" Centorea said as her blouse is starting to see through her large I-size bust.

However, the slime didn't get contained by Raven's magic for so long as the spell breaks and the slime girl covers Centorea all over.

"Noooooooo!" Centorea shouts as the slime girl's hands covers Centorea's breast, absorbing the moist from her chest.

'Impossible! There's no way she could've broken my spell!' Raven thought as she press on her com-link "Guys, I couldn't contain her with my spell, she's too gooey."

"Then we shall surround her." Starfire said as Raven lets out the Titans and the Monster Girls out of the portal to surround the goo covered Centorea.

"Heeeeelllp meeeee." Centorea moaned as the goo girl absorbs her wet behind.

"Alright, there aren't any wet people around so give up now!" Miia demands as the goo girl finishes absorbing Centorea as it gets off of the Centaur taking her basic shape as a girl once more.

"There...aren't...any..." the goo girl mimics which confuses everyone.

"Okay, what is she saying?" Beast Boy asked.

"I think she's trying to communicate with us." Raven said looking at the girl in question. "She mimics the way we say like trying to find the right words."

"Like how Star's lip contact to understand different language." Cyborg notes.

"But what is she saying and why is she here?" Centorea asked as they all watch the goo girl moving her arms like she's stirring a wheel. "Driving?"

"Inside...broom." the goo girl said remembering where she came from as she nodded Centorea's answer.

"So she got inside a car...the T-car!" Beast Boy deducted. "She came from your car, Cy."

"How was I supposed to know she stuck on the T-car? I didn't see her anywhere." Cyborg said crossing her arms in defense.

"What do we do now, darling? She might do something lewd on us." Miia asked hiding behind Beast Boy.

"She's not doing anything for now." Beast Boy said with an idea "Maybe if she can mimic our movements, we can understand better if we do something that she'll mimic us."

"That is a great idea, Mr. Darling." Agent Smith walked into view and everybody jumped to look at her.

"Hey! Who the hell are you!?" Cyborg demanded from the tall black haired woman, and the demoness checked her out.

"Agent Smith, I work for the exchange program and I have come to tell you that Suu here is to be living with you from now on." Smith replied as she ignored the grey skinned girl and focused on the green teen. "Do you understand, Darling?"

"Y-Yes, ma'am!" Beast Boy saluted the older woman.

"So her name's Suu." Starfire said as she smiles with glee. "That means she's our new friend!" she squeed.

"Well, I suppose if Ms. Smith said so." Centorea sigh.

"I don't care as long as she doesn't come into my room." Rachnera said.

"Wait how on earth did you get inside the Tower?" Cyborg asked the government agent.

"Oh, that demoness over there blew up the door, so I let myself in." Ms. Smith states as the empath flinch that the agent knew her heritage as she remembers her encounter with Suu and the dirty thoughts about Argent's session. "Make sure Suu stays away from lots of water, and there will be some renovations for the girl's rooms sometime by the weekend."

"Wait, don't we get a say in this?" Raven asked glaring at Ms. Smith.

"You should ask Mr. Darling about it." Ms. Smith trolled the empath with a cocky smirk.

"But what if a villain shows up at the tower?" Cyborg asked her.

"Don't worry, I've made sure no villains would dare to set foot on the tower, fufufu." Ms. Smith told with a silent laugh as she adjust her glasses. 'If those crooks lay a hand on those girls...even I don't want to think what will happen to them.' "You'll get a lot of less crime in this city, you know."

As Ms. Smith walks out, the Titans and the Monster Girls are left in the room as Suu waves her arms at Ms. Smith goodbye.

"Well, I guess Suu's now a member of our family." Beast Boy said as Raven points out.

"How are we gonna explain that to Robin?" Raven asked as the Titans realize it as well.

"We can say that its good for the publicity." Starfire states positivity.

"As long as Suu stays away from my Darling, then its good enough for me." Miia said holding Beast Boy's arm.

"Hold on, Miia. You cannot be selfish on Master!" Centorea said grabbing the changeling's other arm.

As the girls fight over the changeling, the Titans just walk away as they do their business. Its just another day at the Tower.
