Author's Note: Here it is, the last part! I almost didn't want to end it but then the whole point I was going for would be recked. I hope to write a longer fic next, so maybe I will use this as a backstory or something and refer to it now and again. Whatcha think?

Also this chapter has been edited for being much more graphic than the last chapter. It was always supposed to be more intense and can be seen in it's unedited form in the Turtlecest livejournal community. If you google Turtlecest it pops right up! Thanks Sinisstar for keeping me mindful of how far to push the M rating, but I think the last chapter can be considered a high M ::cough:: hopefully ;) Advice is always welcome! Anywho, here it is...


That night Donatello waited for the rest of his family to be in their respective bedrooms before slipping quietly out of his own. Months earlier he had learned the sleeping schedules of his family, knowing exactly when they would give up on their nightly activities and go to sleep. Don moved silently through the liar, smiling as he passed Mikey's room. At first Don had been surprised to learn that Mikey stayed up later than most of the family once he was in his own room; apparently comic books took precedence even over sleep. But as of 20 minutes ago Don knew his brother would be passed out, probably an open comic book clutched to his chest.

Don neared Leo's bedroom and was happy to see he was right about another sibling's schedule. Even this late, Leo was still up meditating to the light of two lonely candles. Donatello paused a foot away from his brother's room. He had developed a plan after the events in the dojo that afternoon. He would be the first to admit it wasn't much of a plan but this was a complicated situation. The night after Leo had left Don without a word, Don had sneaked into Leo's room looking for an explanation. He had continued this for a week in search of an answer to his brother's sudden cold demeanor, but as Leo continually ignored him and kicked him out, Don had given up.

Don ran over the plan in his mind. Step one involved engaging Leo in conversation. Well, just getting him to talk civilly, Don amended as he inched closer to his brother's room. He would then move on to step two, which involved him slipping past Leo's abruptly built emotional walls. Preferably through words, not actions, Don thought unhappily. After all, his actions in the dojo hadn't exactly worked out as he had hoped. Then Step 3: getting Leo to admit to what was wrong or offer a decent explanation for why things had to stop.

Quietly, Don slipped into his older brother's room. Leo was facing the doorway, sitting with his legs crossed. His eyes were closed and his breathing steady. Don took two steps forward then stopped. The candle flames seemed to be dancing in the still air of the room, the light casting shadows on the walls. Don remembered once comparing his brother to those same strong flames and his stomach clenched. He knew it was still there, the passion inside Leo. Something had just made Leo decide it shouldn't be connected to him anymore.

"What?"

Leo's voice was low but Don jumped at the abrupt break of silence. Don's mind blanked and he found himself frantically trying to remember his plan.

"What's wrong?" Don asked bluntly.

His voice was steady but he shifted his weight uncomfortably from foot to foot. Not exactly step 1, he thought gloomily, wondering why his reliable brain had decided to abandon him at that moment. The silence stretched in the dark room, and he was afraid Leo would once again kick him out. He stopped shifting his weight, planting his feet firmly on the floor as if Leo would try to tackle him out of the room. After the events earlier that day, Don was resolved to get an answer. Leo used to blaze like the sun, Don thought as tender moments from the past bubbled to the surface of his mind, it's like he's suffering from a perpetual eclipse. The memories caused something to spark in the pit of his stomach and he bit his lip.

"What do you mean?" Leo finally asked. His tone was cool. He opened one eye a crack, looking at the solid form of his brother.

"What was that earlier today in the dojo?"

"I just did what you wanted, Don," Leo replied shortly.

He stretched his arms above his head and stood. Don waited for more but it never came. Instead of going to the bed and ignoring Don like all the other nights, Leo began to walk towards him. Don's heart raced as his brother neared then plunged to the floor as Leo passed him to exit the room. Don turned to face Leo's retreating shell.

"That's not what I wanted, Leo," Leo paused, turning his head to look at his brother with a raised eye ridge. Don felt himself blush.

"…well, it was….kind of….I mean no!" Don stuttered, "I was trying to get you to admit that you still feel something for me. Damn it Leo, in the dojo I could feel you wanting to act on your feelings but instead you acted detached and manipulative, using how I feel for you to make god knows what point! Just tell me what's wrong!"

Leo clenched his fists at his sides. The memories of earlier that day had been haunting him ever since and only added to the guilt weighing on him. He hadn't been thinking and as a result had done the one thing he was trying to avoid: hurt Donatello. Leo decided his brother finally needed to hear an explanation. Keeping silent is hurting him, Leo realized in shame, not protecting him.

"You want to know what's wrong?" Leo spun around, glaring at the turtle who had made the temperature in the room increase sharply just by entering it.

"What's wrong is that I've discovered I can't go a day without being with you. I'm burning up inside and I know you're the only thing that can satisfy it and when I'm not with you it's….it's like I'm going through withdrawal, Don."

Leo stepped closer to Donatello until their faces were inches apart. His warm breath mingled with his brother's and Leo felt the desire shooting through his veins like lava. Slowly, Leo reached up and tenderly began to stroke Donnie's cheek.

"I crave you. Need you. Want you. I feel like I'm half of myself without you…"

Leo removed his hand as his voice choked in his throat. He looked away from his brother's hopeful face.

"And I shouldn't feel this way," Leo said in a stern but shaky voice, "That's why I'm so mad, Don. That's why it's got to stop…"

Leonardo turned to leave, not seeing his brother's shocked expression.

"Wait!" Leonardo kept walking, ignoring his brother.

Don felt panic rising in his throat. For a second a sliver of Leo's sun had shone through, only to slide back behind the darkness a moment later. What Leo had just said sounded so final that Don knew if Leo walked out the door it would all be over. He would lose Leonardo for good.

"Leo!" he cried in desperation, no longer caring about keeping quiet.

Don watched his brother's reaction. Leo had just reached the door, but stopped in his tracks at Don's cry. A tremor seemed to run through his entire body. Observing this, Don let himself smile slightly. Apparently, Leo had not been able to close himself off from his feelings as quickly as Don had thought. It never ceased to surprise Don how the simple act of saying Leo's name could turn his brother on so much.

A sense of hope filled Donatello and he moved until he was right behind his brother, turning the now trembling turtle around to face him. Don gently grabbed Leo's hands, drawing him back into the room as he examined his brother's face. Don was surprised by the mix of pain and fear he saw there. He knew the pain was caused by Leo denying his feelings and as a result hurting them both, but the fear was a more complex issue. What was his Fearless Leader afraid of?

To Leo, Don's hold on his hands was painful. Don's touch seared into his already burning skin. Donnie was close. Too close. Leo was having trouble controlling the inferno building in his body. Leo bit back a sob. He had to get out! He tried to pull away from Don but his brother firmly stopped him.

"First of all," Don began quietly, "you're not the only one in this. You can't just decide it has to stop and shut me out."

Leo's eyes fluttered closed. He took a deep breath and when Donnie didn't continue opened them and met his younger brother's searching gaze.

"Secondly," Don moved closer and Leo felt his body scream with need, "I feel the same, Leo. These last few weeks have been torture. The difference is I've accepted the way I feel. I'm not scared of it because I know it's not going to hurt anyone. You have to stop fighting it. You're not going to hurt me, Leo, or the family. It's ok to feel this way towards someone. Stop trying to protect me. I don't need protecting, I just need you."

The words snapped something in Leo. They broke the hold of that little part inside that had always been in the back of his mind telling him he and Donnie shouldn't be together. It had gripped Leo a couple of weeks ago, scared that the feelings he had were so intense and weren't linked to ninjitsu or battle but to his brother. He wasn't sure what the feelings meant, or what would happen next. It was that uncertainty that had allowed the little part of his mind to seize him in a paralyzing grasp. As the little part let go, Leo found himself able to remember his time with Donatello without fear or guilt. He remembered initiating the majority of their encounters without doubt and how the hungry passion would consume them both after going through a whole day pulsing with desire.

His mind slowly returned to the present. The silence in his dark room was deep. Leo was surprised that Don had come in here without shouting at him or screaming that he finally hated Leo after his actions in the dojo.

Instead, Don's presence was soothing. He was being rational and logical and most importantly everything he said was right. He always knew what to say to reach Leo and as usual, he had refused to give up. That's my Donatello, Leo thought as he felt the weight lift. Leo let out a shaky laugh and wrapped his arms around Don, pulling him into a passionate kiss. Don responded eagerly, wrapping his arms around his brother's neck and opening his mouth to welcome Leo's probing tongue. They stayed like that, exploring each other, trembling at the feeling of their two fires being brought together after burning alone for so long. Reluctantly, they broke apart in need of air and Don grinned against Leo's mouth. This was the confidant, in charge, passionate turtle he'd been missing these last two weeks and finally he was back! It made Don tingle with anticipation. Perhaps his smoldering desire would finally be quenched…

"Welcome back," Don murmured against Leo's mouth and Leo sighed happily.

"I'm so sorry Donnie. I'm so sorry…I…"

Don quickly shh'd him and began to walk backwards towards the bed. Leo's eyes sparkled in understanding and he quickened the pace causing Don to stumble slightly as he walked backwards. Leo chuckled when Don made a soft surprised noise as the bed hit his legs sooner than expected and he tumbled back onto the bed. He scrambled onto the bed quickly followed by Leo, who slipped his body between his brother's open legs with a hungry look in his eyes. The look made Don release an aroused mewl and Leo smiled as he planted his hands on the bed next to Don's head, holding himself up so he could gaze down at his brother. Don smiled sheepishly and pulled Leo down so that their beaks crashed together in another lust filled kiss.

Don traced his fingers along the muscles of his brother's arms as Leo's hands deftly moved down Don's sides. He gently gripped Don's thighs and began to grind his hips into his brother's. He broke their kiss to move his mouth to his brother's neck, knowing exactly what to do to get a reaction from him. Don clutched tightly at Leo's shell holding him close. God, it had been too long!

Don cried out as his body arched under Leo's when Leo bit down on a particularly sensitive spot on his throat. Leo stopped his ministrations, lifting his head to grin down at the trembling turtle beneath him. Don was panting hard and he scowled up at Leo's amused expression.

"If I didn't know any better I'd say you planned this," he grumbled. He spoke fast, impatient for Leo to begin moving again. He needed Leo now.

Leo nuzzled his neck and his warm breath made Don squirm.

"I'd never torture you for that long on purpose Donnie," he breathed, "I much prefer to please you…"

"God Leo…" Don moaned. Leo shuddered at the sound of his name and this time Don laughed.

"That's what you wanted right Leo?" he teased, "No gag?" He moved his hands up and began to stroke the back of Leo's neck as his brother paused in his movements, looking away at the mention of earlier.

"Um now that you mention it, Don I'm sorry about that. I didn't mean to--"

"Leonardo," Don interrupted, his voice low and so close to a purr that Leo shuddered again, "enough talk."

Leo felt the fire consuming his whole body and knew that soon coherent thought would be a thing of the past. He quickly reached over and opened a drawer in his desk beside the bed. Sitting back on his ankles, Leo ignored Don's amused eyes as he prepared himself.

"So, you wanted it to stop but kept the bottle just in case hmm?" Don asked playfully, enjoying the feeling of Leo's slick hand on his thigh. Leo ignored him as he put the bottle away and then glanced down at his brother.

"Keep teasing me Donatello and I'll stop right now."

"You couldn't," Don retorted, his breath hitching as Leo's hands crept higher. Leo shifted his body and lowered himself on top of his brother so their foreheads were touching.

"I wouldn't," he answered.

The rhythm that developed made the pair feel as if they had never been apart. Don wrapped his legs around Leo's shell, his hands aching as they gripped Leo's shoulders hard.

Leo buried his face in Don's neck to muffle his sounds of pleasure. Don however found himself unable to keep quiet as the firestorm mounted between them. He bit his lip in an attempt to keep the noises concealed but found himself failing miserably. The noises that escaped seemed to please Leo though, who increased his pace and left Don's neck to brush his beak against his brother's.

"Are you purring again?" Leo panted and Don felt his face flush with embarrassment.

"I-It's called..," he gasped, "c-c-churring!"

Leo grinned.

"Whatever it is, I like it. Don't stop…" he whispered breathily, returning to nuzzle and lick at Don's neck. Don moaned.

"What is it with you and vocal cues?"

But Leo's only answer was to bite down on that sensitive spot again, extracting a whimper from Donatello. The heat was reaching the peak of intensity now and Leo's thrusts became hard and fast.

"Leo!"

The combination of Don's voice and the intense pleasure made Leo's world explode. The feeling of Leo's release sent Don over the edge. He was barely aware of Leo moving his head and taking advantage of Don's howl of pleasure to pull him into a deep kiss.

It seemed like years had passed when Leo finally broke the kiss and collapsed on top of his brother, laying his head on Don's shoulder. They laid there together panting as the waves of bliss washed over them, their passion ebbing back to mere embers. After a moment, Leo rolled off of Don and drew him close. Don happily curled against his brother, reveling in the feeling of his brother's arms wrapping around him. Don laid his head on Leo's plastron, listening to his brother's heartbeat. Leo is right, Don thought contentedly, without each other we're only half ourselves. This is how things are supposed to be.

Leo waited for Don to move but minutes passed and they stayed where they were. In the past, Don would have shifted, gently turning Leo until their foreheads touched and they could lie together talking for the rest of the night. Tonight Leo knew he had a lot to apologize for. Even though he was sure Don would tell him he was already forgiven, Leo needed Donnie to know how sorry he was for being so stupid, how much he had missed being with him and how he truly cared for him.

Another minute passed and Don still didn't move. Leo began to wonder if he had hurt his brother again unintentionally. He squeezed his brother's arm, growing worried.

"You ok Donnie? Did I do something wrong?"

Don remained silent, but Leo felt a shiver run through his brother. Suddenly Don shifted, and Leo watched in surprise as Don straddled him. Leo felt the fire flare in the pit of his stomach and begin to spread as he met his brother's fiery gaze.

Don glared down at his brother, his lips twitching.

"You still have two whole weeks to make up for…"


All done :D reviews are most welcome! I've got another one-shot in the works and I'm aiming to start a longer story as soon as I decide in a good direction to take it. Hope you're not sick of Leo/Don yet, cuz those plot bunnies won't leave me alone...
