Geo: Here is the next installment.


It was a calm night in the Loud House as everyone was asleep, everyone except Lisa of course. "Almost done." She yawned as she added the last drop of a green liquid into a purple one.

*EXPLODE*

"LISA!" Logan yelled with a twitching eye as an odd teal colored smoke filled the house and entered their lungs.

*The Next Morning*

Logan gave a yawn and saw Luan wasn't in bed. He sat up as a strong scent hit his nose. "I smell chicken and waffles!" He said in an excited tone as he got dressed in a black tank top and shorts and jumped through the vents.

*Kitchen*

Geo was making chicken and waffles when he heard loud banging from above. "Looks like Logan's awake." He pressed a button and a vent opened, followed by Logan falling into a chair. "That felt like some Wallace and Gromet type shite!"

"Not really, here's your pl-HOLY SHIT!"

"What! Is there a spider on m- WHAT THE FUCK!?" Logan exclaimed.

"Dude your ears! They're gone!" Geo told him when he saw something twitch in his strange white and black hair. "Uhhhhh dude, your head." He pointed up. "Huh?" Logan touched the top of his head and felt something soft, VERY soft. "What the!? Geo! Where'd ya go!?" He said in a panic. "Dude, I'm right in front of you." He then saw a bunch of floating clothes. "AHH GHOST!"

*SPLASH*

"I'm not a ghost, I think I'm invisible. And OWWW! Why'd you throw hot coffee in my face you fucker!" He screamed.

"Why are you two yelli-GHOST!" Luna exclaimed, picking up a pot and throwing it.

*CLANG*

"AHHH HEAD TRAUMA!" Geo held his head when he fell on the ground with color on his body again. "Oops sorry Geo!" Luna panicked as she rushed over to him. "I smell bacon!" She lifted her head and shot her tongue from her mouth, getting a few pieces in her mouth. "Okay so she is part frog." Logan muttered.

"Hehe. Hey guys, I got a new joke!" Luan said with a chuckle as she walked down stairs and into the kitchen. Logan's mouth dropped when he saw her and his tongue stuck out. Luan had brown wolf ears on her head, a long bushy brown tail, and two small fangs sticking out of her closed smiling mouth. He then felt the blood in his head splatter out of his nose and something stand on end that wasn't coming from his crotch. He turned around to see a pure black white tail sticking out of his tailbone. "Looks like you should High-Tail it!" Luan laughed.

"Oh boy, that was hilarious and I'm a doggy!" Logan chuckled as the tail flicked around, he then tackled her and bombarded her with kisses, making her moan. "Actually it's a fox tail with wolf traits." Lisa spoke with a yawn, showing tiny bird wings on her back. "Lisa, is this because of last nights explosion? Because I'm okay with this!" Logan said with a smile, showing long and sharpened canines as Lucy walked in. "NEKO WITH WINGS!" He yelled in shock as from the back of Lucy's dress was a pair of bat wings, a tail was protruding from under it and two golden cat ears were poking out of her black hair. "Lisa, I take it you're responsible for this?"

"Yes." Without warning Lucy hugged her. "Thank you, this is awesome!"

"Ummm you're welcome?" Lisa said confused.

"Hey guys" Lincoln said as he came out of his room with a smooth white tail coming from under his shirt. "Uhhhh. Lisa, can you explain?" Logan spoke as he used his tail to wipe the drool from Lucy's mouth skillfully.

"Alright I'll explain."

*1 hour later*

"Why that explains it, I guess." Logan said while looking at Lana, whose only difference was that she had a pig tail. Other than that, nothing has really changed about her. As for Lola, she had fangs and a short tail, making her freak out and let out an ear piercing scream.

"SHUT UP!" Logan barked at her, making the diva whimper in fear. "Ooh~Lala! I love it when you get all Alpha Male!" Luan whispered into his ear, making his tail stand on end, give him a stiffy and drool come out of his mouth.

"AHHHHHHHHHHH!" Leni screamed as she ran into a wall. "I CAN'T SEE!" Lisa rolled her eyes. "Leni take your sunglasses off and you'll be able to see." Leni then removed them from her face. "Ahh, much better." She said with a sigh as she walked downstairs. Leni's nose was pink and she had a long pink tail. "Leni, what the fuck are you?"

"I think she's a mole." Lincoln snickered.

"No, she just had sunglasses on, that does not make her blind." Lisa said. "She might be a mouse."

"That explains why she's going for the cheese." Geo spoke as Leni was nibbling on the cheese in the fridge. "Hey has anyone seen Lori?" Lynn asked as she slid down the staircase with brown fox ears, a long fang and a tail. Lincoln blushed heavily as she landed next to him. "S'up Lincoln?"

"Uhh…hi?" He spoke as his blush got darker. "You're sitting on my tail."

"Oh! Sorry 'bout that!" She said with a sweat drop and a blush of her own as she quickly got up.

"Let me guess, Lisa?" They heard Lori's voice as she exited her room. She had a long scaly tail and green eyes wth slit pupils.

"Whoa someone needs a Snickers!" Luan said as this got everyone *Except Lori* laughing. "Finally, a good one!" Lynn chuckled loudly. "Where's Lily?" Lincoln asked said baby floated down with moth wings on her back. "Awwww!" They all said as she landed on Luan's head.

"Poo poo!" She cheered while Luan cuddled with her. "Anyone up for pancakes?"

"I thought we were having chicken and waffles?" Luna spoke. "Oh yeah."

*After breakfast*

"My stomach hurts." Luan groaned in pain. "Mine... too." Lori spoke, letting out a small belch. "That's because you guys are carnivores."

"Then why isn't Lola sick?"

"Tasmanian Devils are omnivores." Lisa said. "Same with Lana."

"More please!" Said girl spoke with a snort.

*Later*

Lincoln yawned as he sat up and saw Lucy sleeping above him and Lynn sleeping on the floor, kicking her legs in her sleep.

'Oh yeah, animal DNA.'

*Attic*

Logan gave a yawn as he woke up only to see the attic was a wreck, even more then usual. "Was there a sister fight again?" He thought aloud as he heard some growling. "Lu?" He spoke quietly as the growling got louder "Luan, is that you?" He asked as the prankster jumped out from a pile of boxes, looking very feral and dangerous with his large bushy hair not in a ponytail and her skirt torn a bit.

"Whoa!" He exclaimed as he fell down the attic stairs and hit his head hard on the floor, causing it to open and seep out blood. The smell of blood was enough to make Lori *who was walking upstairs* go crazy and stare at him. "What happened to you?" She asked while licking her lips, trying not to eat him. "Fell down the stairs." He said while slowly getting up. "Hey look, Bobby!"

"Where?!" She said excitedly as he crawled back up and locked the door.

*Geo*

"You smell blood?" He asked Luna. "No why?" She raised an eyebrow.

"Logan's is now bleeding and Lori was about to eat him." Both of them jumped at the sudden appearance of Lucy. "And no, it's not making me crazy, I'm a fruit bat." She spoke as she ate an apple, core and all.

"Lucy is anyone else acting weird?"

"Leni-"

"Okay, weirder than that." Geo said, being more specific. "Lori, Lynn, Luan, and Lana."

"Hmmm Lana is normal, I guess. What're the others doing?"

"Lori was contemplating on eating Logan, Luan accidentally made him bleed wth a feral look, and Lynn is acting more clingy and playful to Lincoln than normal." She responded in a dull tone. "We need to see Lisa."

"Why?" Luna asked. "She might know what's going on and stop Lori from eating my best friend!" Geo exclaimed.

*Lisa*

"Hmmmmm." Lisa spoke while sipping a nectar smoothie. "It would seem that Luan and Lynn have entered a heat cycle."

"Say what now?" Both Lincoln and Logan poked their heads out of the vents. "They've entered heat." She repeated. "Lana and Lola might later on, but we won't know until they show symptoms."

Logan and Lincoln looked at each other, gained very perverted smiles and zipped back into the vents as Geo used his tongue to pull them back down. "Hold on a minute Catdog, you guys should know something first!" Luna said. "And that is?"

"Wolves are very predatorial when it comes to mates, Logan, you have to assert your dominance over her because of you're not careful she'll kill you." Lisa said in a grin tone. "Got it." And with that, Logan left. "Foxes like to play and tumble, you'll have to beat her in the game to mate, Lincoln."

"Okay."

*Logan*

"Luan?" The clone said cautiously as he crawled out of the vents when he heard her growling again. Suddenly he pounced him and snarled in his face. "Luan… GET OFF ME!" He barked making her flinch as she got off him, however she wasn't going to let some beta boss her around. She growled, making him flick her nose. She growled again this time even louder and bit his hand

"NO! BAD LUAN!" He yelled. Logan then slapped her very hard, leaving a dark bruise and a few deep and jagged cuts from his claws, making her back off and whimper.

"Bad girl!" He scolded angrily as she looked down. "Sorry." Luan muttered sadly as her ears drooped.

"Never bite me." He said in a stern tone "Or you get no sex for a month and sleep in the living room." Hearing this made Luan cry. "I'm sorry!"

"Just don't bite me."

"I won't I promise!" She sobbed before hugging him.

"It's ok." He whispered as he rubbed her head and pet her tail.

"So you still love me? Even though I tried to hurt you?"

"I could never hate you." He spoke with a smile before kissing her, making her tail wag like crazy and her eyes widen as she let out a soft moan. 'I think he's getting better.' She thought in happiness as they then started frenching and fell on the floor, tearing each other's clothes off.

*Lincoln*

"Lynn?" Lincoln said cautiously. "Hello?"

'Where is she?' He thought confused when suddenly he was tackled. "OOF! Ow!" He groaned as he hit his head on his desk.

"Are you ok?" Lynn asked. "Yeah." He muttered

"Sorry 'bout that Linc!" She giggled a bit with a blush as he got up and dusted himself off with Lynn, who started to hump his leg uncontrollably.

"Ok this is both kinda arousing and weird." He muttered as he started to get hard, much to Lynn's delight.

"Time for some fun!" She smiled as she stood up and kissed his nose. "Tag you're it!" She whispered and ran off into the vents. "Hoo boy." Lincoln sighed before chasing her.

*Logan*

"That…was…awesome." He panted with a smile as he and Luan were were wrapped up in a blanket on a waterbed. "I know." Luan yawned and snuggled into his chest. "What was that, round 5?"

"No I think it was 12." Logan said with a smile as they dozed off, but not before having round 13.

*Geo*

"I think they have it all under control." Geo moaned as Luna not only deep throated him but also wrapped her tongue around his entire length. 'Oh yeah, totally forgot she was a frog.' He thought in bliss as he came for the 7th time into her mouth. "Luna you're a goddess!" He moaned as she slid off with a wet plop.

*Lincoln*

"Gotcha!" Lincoln said as he tackled Lynn and giggled a bit. "I win!" He smiled and panted. "Yeah you did, now for your reward!" She said with a smirk before swiftly tearing both of their clothes off. "You look a lot better naked!" She said with a blush. "Yeah same with you." Lincoln smirked with a deep blush before she started kissing him and wrapped her tail around his. 'It's so soft!' She thought as she rubbed his slowly growing hard on.

Lincoln lowered his head and started to suck on her tits, making her release a pleasurable yipping noise. "More! More!" She moaned when he started fingering her, making her moan louder than before.

"Yes yes!" She cried out as her knees bucked and she came onto his fingers and hand, which he licked

"Mmm. It's sweet and tasty." He complimented as she blushed immensely. Lynn then got on all fours with a sly smile and spread her legs open. "Fuck me! Please!" She begged as her tail wagged like crazy while Lincoln smirked.

"With pleasure." He walked over and rubbed her slit before thrusting inside of her, making Lynn yelp. "Man it's tight!" He groaned as he started to move around. "Oh!" She moaned happily as Lincoln started to kiss her.

*Geo*

"Yep, they're good." Geo said with a chuckle while Luna slept on his chest happily. "So I guess we're stuck like this." He said.

"Yeah, but I don't really mind." Luna told him with a smile.

*Lincoln*

"Better Lynn?"

"Yeah…much better." She said with a heavy breath and with a smile as she snuggled into his chest.

*The next morning with Geo*

"*Yawn* That was a good sleep." Geo woke up and groaned as he got out of bed when he saw that he no longer had a tail. "Aww!" He complained.

*Logan*

"How long before he realizes I just put paint on his tail to match his bedding?" Logan asked with a cruel smile.

"3 hours." Lincoln chuckled as the sisters came down.
