A/N This is happening a little faster than I expected. That's alright with me. How about you?

"Raph?" Leo hissed as they walked into a copse of trees in the park. "Donnie, how accurate is your gps?"

"To about five meters, er, about fifteen feet. He should be right around here."

"Dudes, he's like right over there." Mikey pointed. Sure enough, Raphael was leaning against a tree with a few unconscious foot soldiers around him. He was rubbing his cheek, looking dazed.

"Raph! Are you alright. I'm so sorry. I should have come after you." Leo stammered, running up to his brother.

"Huh?" He looked up, and locked eyes with his brother, finally focusing. "Yeah, Leo. I'm fine. S'alright."

Mikey ran up and peered into his face. "How'd you get that cut, bro?"

He pulled away. "Foot got me with a kunai. It's not deep. Nothin' ta worry about."

"You should have Donnie look at it when we get back to the lair."

"Yeah, yeah." He walked past them and followed Donnie back to the van.

"Dude, they both are totally zonked out."

"You've got a point, Mikey."

"Dude! Bro! What if, like, what if they had their brains sucked out by zombie vampires?" He shuddered and grabbed Leo's arm.

"There's no such thing as zombie vampires."

"Okay, but what if it's like the Kraang, though?" He tugged his brother's arm.

Leo wanted to argue, but the Kraang had suddenly reinserted themselves into their lives after an absence of nearly a year. "We'll keep an eye out."

"Maybe we should keep two eyes out just in case."

"Sure. Both eyes then."

…...

"I'm beat, guys. I'm heading to bed." Leo trudged in and headed for his room. I can nap for about an hour or two, then head back out. If the Kraang are active on Earth again, I'll have a better chance of finding more of that mutagenic ooze.

"Leonardo, I would like a word with you." Master Splinter walked out of his rooms and eyed his sons. "Michaelangelo, you as well."

"Heh, you guys are in trouble," Raphael teased.

Donnie patted Mikey on the shoulder. "Sorry little brother. I'm off to the lab to start working on the stuff we found."

The two blue-eyed brothers followed their surrogate father into the dojo. "Michaelangelo, do not bother to sit down." He gulped aloud. "I just wanted to remind you that if you use foul language, I will know about it."

"H-hai, sensei."

"Tomorrow you have to do an extra ten flips with your morning routine."

"Hai, sensei." He bowed and backed out of the room.

"Leonardo. Tell me what happened on this evening's patrol." Splinter straightened his long beard and settled in.

Leo described what they had discovered about the Purple Dragons and the Kraang seeming restart their work on earth, but left out Donnie and Raph acting a little dazed. "Then we caught up with Raph who had found some Foot and came home."

"That is troubling, my son. The Kraang are a terrible foe. I have studied the arts of war and combat. One of the basic tenets is to know thy enemy. These Kraang are unknowable."

"Donnie thinks he found another Kraang communicator, and April received an odd transmission on her Kraang detector. Maybe we can monitor their activities and sabotage their plans before they are able to enact them."

Splinter grinned. "Now you are thinking like a ninja. Work in stealth. Confuse your opponent." He pushed himself to his feet and Leo did the same. "Keep me informed of anything you find. And extend an invitation to April to stay with us should she feel threatened."

"Hai, sensei." Leonardo rubbed his eyes as he walked back to the common room. He expected to see Raph watching some action movie and Mikey to be reading a comic, but no one was around. The door to Raph's room was shut tight and Mikey wasn't around.

He walked to the lab, intent on seeing what Donnie had discovered with the Kraang device. "April," he heard from inside.

"Nope. Not walking in on that landmine," he said to himself, turning on his heels. Leo had enough experiences of walking in on Donnie when he was daydreaming about April to know when not to disturb him.

Leo thought about napping, but since everyone seemed to be busy, he decided to sneak out early. He double checked the common room, jumped the turnstile and ran down the unused tracks to enter the streets of New York.

…...

Raph flopped down on his bed and stared up at the ceiling. His torn posters of Jessica Alba and Megan Fox didn't even grab his attention. Not even his secret photo of Emma Watson affected him. "A mutant. Not evil either." He touched his mouth, reliving the scene.

"Hell, I wouldn't even care if she was evil." He had no idea what caused him to kiss the girl. It was like another force, almost an instinct took over him. Splinter had raised them to respect and almost even reverence women.

He had never once had the urge to grab a girl and kiss her. Not April, definitely not that bitch Karai, not even April's punky friend Irma. Raph grinned, trying to force the seconds to tick by faster until he saw Tailynn again.

…...

"April," Donnie sighed. "I can't believe April kissed me." He whirled around the lab, grabbing tools, hooking up the computer parts he found to some spare housing he had lying around.

"She wants to talk to me more, too. It's like a dream come true."

"Ew, dude! She actually kissed you?"

"MIKEY?" Donnie yelped and rocketed into the air and out of his daydream. "Mikey!" He spun and glowered at his brother. "What are you doing in here?"

"Iunno." He shrugged. "Soooooo, did she really kiss you, bro?"

Donnie turned scarlet. "That's none of your business."

"Sure it is. I've been trying to figure out why you and Raph were acting like zombies when we found you. I was so worried it was a zombie vampire, like a zompire or something. Or maybe the Kraang. April kissing you would make a lot more sense."

"I was not acting like a zombie."

"Dude, you were straight up out of Alfred E. Romero."

"Maybe I do lose focus when I think about April, but don't you do the same thing with comics?"

"That's different, bro. Now detective Mikey is on the case to solve what made Raph zonk out. Maybe April kissed him, too."

Donatello waved dismissively as he started work on fixing the tech. "Maybe." Mikey giggled. Donnie loomed up behind him and put a hand on his shoulder. "Say that again and I'll make anything that Raph has ever done to you look like it was done by a kindergartener."

"Ulp. Later bro!"

…...

Leonardo went up through the abandoned subway entrance and poked his head down the street. All clear. He dashed into a nearby alley and leaned against a wall, planning on where to widen his search to.

The escape ladder sighed above him and something dropped down in front of him. His katana were out, but the figure had landed pressed up against him. He twisted his blades, ready to slash from behind given the first indication of an attack.

Instead, the figure wound its arms around his neck and pressed its lips to his. "Did you miss me that much, Muscles?" Leo didn't have a chance to respond in the brief moment she had freed his mouth.

He was in shock. Sure, his body responded just fine, but his mind was a blank encephalograph. Who was this girl? Why was she kissing him? How did she know him? Why wasn't he stopping her? He sheathed his swords and ran his hands down her back. Soft. Velvet. Silk. He peeked his eyes open. A mutant? A cat? Is that a scarf?

Her tongue was a little rough as it poked into his mouth, but he had stopped caring. Maybe he was tired. Maybe it was finally being able to act out on his pent up teenage boy frustrations. Either way, kissing this girl seemed like the best thing that had even happened.

Leo ran his hands down her sides to her hips, and she stepped closer to him. A kunoichi's weapons are not just the sword and the bow. A female ninja can beat a male twice her size with a simple gesture. He forced himself to break away with Splinter's lesson ringing in his ears. "What's this about?"

"Come on, Muscles. Don't be like that. I'm glad to see you traded in those little knives for some bigger ones, though." She ran her hand over the hilt of one of his katana. "Although I think I like the red mask a little better than the blue."

"Red?" Leo's heart was still pounding and he was short of breath, but the pieces were falling into place.

"Yeah. We were supposed to meet up tomorrow, but today can work, too, Raph."

He shook his head and tried to put some space between the two of them. "Raph's my brother. Who are you?"

She covered her mouth. "Oops. I just saw turtle and I assumed you were him. I'm Tailynn."

"Well, sorry to disappoint, Miss Tailynn. I'm Leonardo. I'm sorry, too, that he didn't mention you."

"He doesn't seem like much of a talker, anyway." She put her hand on his shoulder. "I'm really sorry about jumping on you like that, it's just that-"

"You thought I was him. I get it." He tried to turn and hide the shame he was sure was on his face.

"We can go with that, sure." She straightened her scarf. Even though Leo knew she was somehow involved with Raph, he couldn't keep his eyes off of her. Her petite waste, her curves that were feline, but feminine, her pale blue eyes, her gleaming grin. "Actually, I'll propose to you what I did to him. Help me find the Kraang."

"The Kraang. What do you know about them? Are they restarting their invasion?"

"I know because of that ooze they kept dumping over the city, my life has been a nightmare for the last year. I need to find that ooze. And I need to destroy every single one of those pink blobs."

Leo nodded, finding that a smile had reappeared on his face. "I like the sound of that. But how do I know you're not working with Shredder? Or the Purple Dragons?"

Tailynn groaned. "Muscles asked me the same thing. What's a Shredder? Like a food processor?"

He wanted to trust her. More than that, he wanted to feel her body in his arms again. "He leads the Foot Clan. A ninja. He has connections with the Kraang and the mutagen. In fact, he's made mutants of his own people."

She hissed. "Who would willingly curse themselves to this."

"I don't think they were willing."

Tailynn clenched and unclenched her fists, breathing hard. "Then he's going to pay, too."

Leonardo couldn't help himself. His fingers itched to be buried in her fur. He swallowed and tried to keep talking. "How did it happen?"

"What?"

"My brothers and I were turtles. We landed in the ooze seventeen years ago and were raised in secret. How did it happen for you?"

She looked down the alley. "A canister of that ooze smashed our window and splashed on me. My brother and sister tried to help, but they got it on themselves. The Kraang found us not long after and took us. I was able to escape when there was a power surge, but-"

His arms were around her before she could say any more. He wanted to comfort her, but he couldn't keep away from her either. Tailynn's scent, her essence called to him. Is this some kind of animal instinct? I wish I could ask Donnie... "We'll find them. I will make sure we get them out."

"Aren't you just a regular Superman." She stroked his cheek.

"Heh, I guess that's better than Captain Ryan." He leaned down, stopping a breath away from kissing her again. "I think we can work well together, Tailynn." She shuddered as he breathed her name, and that did it. He captured her mouth with his and cradled her head in his hand.

To hell with being careful. If he was going down the path to ruin, it was worth it for this moment. She moaned as he ran his hand down her back curled around her tail. Leo pulled her close, melding her to his plastron as they deepened this kiss.

She grabbed his shoulders, digging in with her claws every so often. Tailynn had forgotten what it felt like to be held, to be caressed. She had lived without much human contact for a year. Now to have this handsome, albeit green man interested in her. Not just one, two. And brothers. She grinned. "You're better at this than your brother."

Leo paused for a minute. He had no idea what Tailynn and Raph's relationship was. How long they had known each other. What they had been through together. Then he noticed Tailynn's seductive gaze. To hell with Raph, too.

But something else caught his eye. Purple Dragons.

God. Damn. It.

He ducked under Tailynn's arm and drew his left katana, slashing the dragon. He backed up, covering his gut. Blood seeped out through his dark clothes. Leo caught another ninja with a kick and slammed him to the ground under his knee. "Can you guys pick a worse time to show up? Seriously?"

Leo drew his other katana and slashed forward, catching two dragons. They fell, not mortally wounded, but unable to fight. "Tailynn!"

She leaped, a huge vertical for a petite cat, and landed square on the dragon's shoulders. Tailynn kicked forward and the ninja smashed into a dumpster. The cat shot ahead and jabbed her elbow into the face of the last enemy.

The turtle was impressed. She wasn't a ninja, but she knew self defense. Sirens blared down the road. "Let's go!" He pointed to the roof. The two jumped from stairwells and emergency ladders until they were on the roof.

The stars were invisible thanks to the myriad lights coming from downtown Manhattan. It was a still, cool night. "Are you alright?"

She nodded. "Just warming up for the Kraang."

The spell he had felt in the alley had diminished. "How long have you known my brother?"

"In total? About two hours longer than I've known you."

"You make friends quickly, then, huh?"

Tailynn smirked. "There must be something in the air. I'm usually pretty affectionate to people I like."

"Is that so?" He sat and let his legs dangle over the edge. She perched next to him. "My brothers and I aren't usually so affectionate. Especially Raph."

"You need a woman in your lives, that's all." She twisted and straddled his lap. "And if we're going to be hunting the Kraang together, I'm going to be in your lives a lot."

Guilt clouded his vision for a moment. How could he do anything with a girl that his brother was likely interested in? Then she inched forward and kissed him, and he forgot everything again.

He tried to control himself, but they way she was kissing him, the way she smelled, (God, her scent! It was like vanilla and green grass. So much better than sewer stench.), the way she grabbed his plastron, it was too much.

She slid her fingers through his mask and slipped it off. Her tail caressed his thighs, driving him crazy. "Hmm, it took a little while for you to start enjoying this, huh?"

Leo growled and pulled her closer. "I've been enjoying it from the start. Turtles are just good at keeping that hidden." He ran his hands up her sides and caressed her breasts. "I just can't seem to keep my focus for some reason."

Tailynn purred. "I bet you're just so focused, too." She nibbled his neck.

He could feel himself slipping. "I-it's something I pride myself on."

"Then I'll be proud if I can make you lose that focus, Leonardo." The way she said his name, part whisper, part purr, sent him over the edge and his length fully emerged. She leaned back a little and her eyes widened. "That simple, huh?"

She grabbed his hands and ran them up and down her body. "You need to know, Leo. I find you incredibly attractive. That said, I tried to tell you before that I'm in heat."

He leaned back and sighed. "Oh, good. I thought I was losing my mind. I can't seem to keep my hands off of you." It made so much sense. The inexplicable attraction. The desire that made his gut ache. He had never felt this before, but he had never been around another mutant in heat before.

Tailynn smirked and straddled his prone body. "No, that's just me." She rested her arms on his pastron and kissed him.

This is it, he thought. I can't believe this is happening. Leo had always tried to keep himself disciplined and focused, but he was seventeen for God's sake. He couldn't help thinking about girls and sex. Now it was finally going to happen.

Leo pushed himself up with his elbows and grabbed her hips, positioning her over his length. He nuzzled and suckled her soft breasts. And he waited, waited for her to take that final step. Waited for her to make the decision.

Of course she teased him. She rubbed her body on his hard length. Length was the right way to describe it, too. I'm going to have to look up some information on turtles when I get the chance. It had been so long since she had kissed a boy, let alone anything else. Being in heat was something she had never gotten used to. It was so difficult to be like this for a week every month. Why shouldn't she enjoy any part of her new life.

Leonardo moved his hands lower, rubbing her with his textured flat thumb. Tailynn moaned and her legs shook. He grinned up at her.

"I could get used to that, Supes." She kissed him, running her small rough tongue over his. Leo guided her hips with one hand, while pleasuring her with his other. Tailynn grabbed hold of the ridges on his plastron and slowly, so slowly, lowered herself onto his length.

He felt his tip slide into her wet warmth and had to force himself not to jam himself up to the hilt into her body. He let her tease him. But he wasn't going to play fair. He found a sensitive spot on he body and rubbed it, pinched it, teased it endlessly.

She squirmed and whimpered on top of him. "You're going to make me lose my mind, here." Finally she had all his length inside her and she groaned as his ministrations brought her to a climax.

"No, I'm going to do that now." She moaned into his kiss and he began to move his hips. Slowly grinding them into her so he could feel and memorize every inch of her. She was so tight and warm around him. He wondered how he could hold out at all.

"Leo!" She moved his hands to her hips. "That part of you keeps hitting me."

"Part?" He moved his hips forward.

"Not that! Well yes that, too." She ran her hand down the front of his plastron, right to where their bodies joined. "This yellow part."

"Turtle anatomy lesson one: plastron."

"I've already had lesson one, Supes." She nuzzled his chin and nibbled his neck. All the while she was riding him.

"Time for lesson two, then." He wrapped his arms around her and stood up. Leo pressed Tailynn against the door to the roof and thrust into her. He nibbled her breasts, switching from one to the other while she moaned his name.

He could feel it coming. She tightened around him and dug her nails into his shell. I've just got to hold out. Just a little longer. Tailynn groaned into his mouth as she convulsed around him. He couldn't hold it any longer.

Then his shell cell started to ring. It'll have to wait, he thought. The phone shut up, and he released inside her, panting. Leo still had her pinned to the door and was kissing her. The phone rang again.

"I should answer that."

"You should get up and we can go again." He caught her eye and she nibbled his shoulder.

"You make a convincing argument." He kissed her again, deeply. This time, along with the need and the hunger, there was passion. A flame ignited inside him. More than a singular instinct. He could feel himself getting hard again, something that even surprised him.

"You really are Superman, aren't you?" The shell cell rang again. Donnie. "Ignore it." She adjusted herself so she could rub on his length. It was unbelievably sensitive, and responded in an instant.

As soon as the phone stopped ringing, it started again. Donnie. What if it was something about the Kraang? What if it was something about Splinter? Here I am having sex with a stranger and my father could be in trouble. I'm the worst son ever. "I really should answer it."

"Let me convince you." She moved to her knees and took his growing length into her mouth.

"Tailynn!" He caressed her soft head, hoping she wouldn't accidentally bite down with those sharp teeth. She reached up and clipped the cell back on to his belt.

"Leo?" Tailynn stopped for a moment glancing at the cell. "Can you answer me? I turned on the walkie talkie function to your cell remotely. Is everything okay?"

"Y-yeah Donnie." Tailynn grinned up at him, using her rough tongue to tease him.

"Why didn't you answer? You sound out of breath."

"I was running. Didn't hear the cell." She sucked on the tip and used her hands to pleasure the rest of his length. "What-ah-what's up?"

"I couldn't find you. I wanted to tell you about the computer parts I found. There's a lot of evidence to indicate that the Kraang are going to try some kind of new invasion. The communicator looks to be just that, a way for the Kraang to have contact with some humans who are willing to work with them."

"Ah!" She grazed her teeth along him.

"Huh?"

"Ah ha! Excellent discovery Donnie. I'll be back home and see it soon. You should get some rest."

"I'll wait up until you get back. Your gps shows you're not far."

Dammit Donnie. "Well I'm working on something. I might not be back for another... hour." Her eyes widened in surprise. "Make that three hours."

"What about the Kraang?"

"We'll look at it with fresh eyes in the morning."

"What if the communicator goes off?"

He rolled his eyes and separated himself from Tailynn. She looked surprised until he bent down and nuzzled between her legs. "If that happens call me."

"What's that? You started to sound kind of muffled." Tailynn moaned his name as he licked and sucked fer most private spot. "Is someone there with you?"

"Go to bed, Donnie." He grabbed the cell and tried to find the mute button. "Oh to hell with this." He grabbed her left leg and thrust into her.

He angled his hips, feeling for a spot inside her that he knew would drive her over the edge. "Leo!" He found it. Leonardo worked inside her, feeling her release over and over.

"God damn! I almost can't take it Supes."

Leo grinned. "I told you I have great focus." I started to slow down, pulling almost all of the way out of her and slamming back inside her. He knew he was close again, but he hoped to bring her to climax again before he finished. He didn't know how soon he could go again after this time.

"Harder, Leonardo. Harder!" The turtle could feel her tightening again and did as she asked. He couldn't hold himself back any longer and came inside her.

"Tailynn! God!" He growled. Leo leaned down and kissed her, running his hands over her soft fur. His arms and legs shook, threatening to drop him on top of her without warning.

"Uh, Leo?"

He took a deep breath. "I know you're busy and all with something, but the Kraang communicator is going off."
