Donatello's Love (Donnie X Reader One Shots)

Cheater!

“All of me, loves, all of you~” Donatello sang along with his radio in his lab, dashing from table to table, throwing together the needed materials to continue his latest ‘invention’.
 
(Y/N) had left not too long ago to retrieve some items from home in order to be prepared to stay the night, and as she would have to take the long trip home to avoid piles of plowed snow that nearly entirely blocked the sidewalks, Donnie took the chance to retreat to his lab and continue with a certain project he’d been working on for a while now.
 
Now humming to the lyrics, the bo wielding teen tinkered around with the sprung-wounded gears on a rectangular wooden base, of which was quite small. Smiling thoughtfully, the mutant set aside his screw driver and lifted up the small contraption to admire his work. A surge of enthusiasm suddenly bursting within him, Donnie reached for his mug to endure another large cup of coffee, and dove back into work.
 
So entranced by his own focus, the purple cladded genius failed to notice the slender figure, of which had now stood at his laboratory doorway.
 
April crossed her arms, quirking an eyebrow. “Hey, Donnie.” She speaks after a moment of watching him so enticed by his tinkering. Slightly jolted by the sudden voice, Donatello fumbles with the screw driver in his palm. As the tool clanks to the floor, Donatello whips around with wide eyes.
 
“Oh! H-Hey, April.” He chuckles with slight embarrassment, kneeling down to retrieve the screw driver. “I didn’t know you were still here.” He admits.
 
The redhead smiled in the slightest at his stammering and mild blush. Those were some things she hadn’t heard or seen from Donatello in quite a while. Not since (Y/N) had arrived, anyhow. She now remembers how much she’s really... missed... Donatello’s bashful attitude toward her.
 
“Yeah, Mikey and I were watching a movie. He passed out on the couch a while ago, though.” She explains with a bit of a laugh. Donnie smiles sweetly in response, turning back around to face his table. He gently turned the volume of his radio down to a soft tune, then continued to tinker. April walked up by his side, casually pulling herself to sit on a bare spot upon the table he worked on. The teenage girl crossed one leg over the other, resting her hands calmly in her lap and looking down at his hands as they glided swiftly across his invention. She bit her lip.
 
“Donnie,” She says coolly, tilting her head to the side. He hums in response, slightly heavy eyes glinting in her direction for a brief moment. “It’s pretty late, you know.”
 
Donnie’s hands momentarily stopped moving, frozen from her statement.
 
Uh oh. 
 
He knew very well the moment Donnie stays up late, if not (Y/N), April will be the one to guide him to rest. No one Donnie knew ever let him drown himself too much in his work; it only leads to sleep deprivation and temporary starvation. However, this time the genius turtle was determined to finish this project tonight. He’d been putting it off far too long by this point.
 
“Uh, yeah.” He says quietly, continuing to work, and alluding all eye contact.
 
April smirked again. They both knew very well she would break him. But, hey, she wasn’t one to say no to a challenge. Though, it would be more difficult now that flirtation was no longer an option.
 
...Not that she would use it...
 
“Donnie,” She urges, leaning closer to him slightly. The mutant tensed, pretending to be completely focused on his work. “You know this isn’t healthy. You need to sleep, Don.” She pries, crossing her arms. “You and I both know very well that resisting sleep only has you stressed in the morning. And a stressed Donnie is a cranky Donnie.” She finishes with a giggle.
 
Donatello nearly smiled at her laugh. That spout of merriment that used to set butterflies in his stomach, but now, did nothing.
 
“What does sleep deprivation do to brain cells, Donatello?” April says, raising her brow expectantly.
 
He froze again.
 
Damn.
 
Sighing, his mocha brown eyes flicker up to her ocean blue irises. There was a moment of silence, before he gives in.
 
“...It kills them.” He admits in a mumble.
 
“And what happens when your brain cells die?”
 
“...You literally become stupider.”
 
“And you just said stupider. Is that not enough proof you should go to bed?” April concludes with another devious grin. Donnie laughed slightly, and she did so as well. However, after a moment, April’s smile fell. She stared at him with seriousness and concern. “Will you go to bed now?”
 
He sighed, setting down his tools and hunching over the table. “I’m almost done,” He rasps, turning his head and offering her a tired smile. “Promise.”
 
April felt her stomach twist at the adorable grin. Biting her lip again, the redhead pivoted her head off to the side. Donnie raised a brow bone at her action, straightening his composure.
 
“Is... Something wrong, April?” The mutant inquires.
 
April then drooped her gaze down to her lap, fidgeting with the hem of her yellow shirt.
 
“No, nothing...” She says in a near whisper, pushing herself off the table and taking a few steps away. “Look, just... do whatever you want. I’m going to head home...” She trails, making toward the door. “Goodnight, Donnie.”
 
As the teenage female began to flee toward the exit, Donatello became frantic, and quickly lashed forward to step in front of her. Fumbling, the mutant regained balance, and looked down at April, as she now stopped and stared up at him with wide eyes.
 
“April,” He says softly, taking a small step forward. “What’s wrong?”
 
Her breath hitched slightly, and the girl inched back with every step he took closer. “N-Nothing, I said!” She exclaims defensively. “Really, Don, nothing’s wrong. I-I’m just tired.”
 
Donatello looked unsure, eyeing her evidently forced smile up at him. April sighed at his expression of derision, and gently rubbed her temple. Caving in, she stepped forward to be oddly close to him, and tilted her head back to meet his gaze.
 
“Okay, fine, Donnie...” She sighs again, crossing her arms with a soft frown. “There is something wrong. Very, very, horribly wrong. Like, seriously,” She rambles, flailing her arms melodramatically. “Psychologically, terribly, tauntingly selfishly wrong!”
 
Cinnamon brown eyes widening, Donatello reaches forward and places a hand on the distressed teen’s shoulder.
 
“April, please,” He urges, “I’m your friend. Just tell me what’s going on. Maybe I can help you.”
 
Gulping, April glances at his hand, then back up into his eyes. “No, you really can’t...” She trails off. “Because, this issue I’m having, just makes me a horrible person...” Drooping her head down, April takes another small step forward. Her chest grazes against his plastron, causing Donnie to stare with mild shock. Despite awe, his hand remained on her shoulder, though he hardly took notice.
 
“I’m just...” She rasps, fully compressed to his chest. “A horrible, horrible...” She began to lean upward. Donatello remained frozen. His lips gaped, the gap in his teeth faintly visible. Eyes as wide as they could possibly be, Donnie’s pupils dilated, and his heart thudding at an alarming rate. April was dangerously close by this point.
 
How ironic could this possibly be?
 
This girl Donnie had felt such blindingly strong feelings for for so long, is now standing before him, leaning in for what would presumably be a kiss. But now, Donnie wouldn’t excitedly lean in, wrapping his arms around her, and kissing her with all passion he had in him, like he dreamed he would. No, now he had someone else in his life. (Y/N). And suddenly April is interested? Why was everything falling out of place all of a sudden? Everything was perfect, why did this have to happen?
 
And most importantly, why was it happening? Did this fiery haired girl develop feelings for Donatello just when he was at such a terrific state in his life with someone he truly loved? What about Casey? He was so sure something was going on between the two of them.
 
Suddenly, just as thoughts of panic were darting through his mind, a pair of plush pale lips met his in a gentle and desperate manner. Donnie didn’t react. Even in the slightest. He just continued staring at this girl as if she’d grown three heads. Aprils hand slowly raised to rest on his as it was still on her shoulder.
 
Donnie felt as though his heart was going to jump from his chest at any moment. Her lips; they were just as sweet as he imagined. His eyes began to droop, and Donnie felt his lips pucker as well.
 
Seconds before he could return emotion into the kiss, a certain someone sprung into his mind.
 
(Y/N)...
 
Donatello’s stomach twisted with guilt; of which made it all the more confusing as to why the Hell he wasn’t stopping this. Furthermore, why he was beginning to contribute to it?
 
There was so many things wrong with this situation. Donatello didn’t know if his current relationship with (Y/N) could survive another trauma like this.
 
But...
 
In Your Perspective
 
The lilac scarf you wore around your neck danced wildly in the wind as you walked down the sidewalk toward that familiar alleyway of which would lead to the lair. Gloved hands in the pockets of the black jacket you wore, you temporarily removed one hand in order to adjust the strap of the large brown purse you carried your essentials in to sleep over at the lair. The brisk late winter air beat on your sensitive (S/C) skin as you strode.
 
You were actually quite surprised Donatello hadn’t offered to walk back with you along the rooftops. It was really unlike him not to obsess over your safety, even if you left the lair for only a short amount of time.
 
Disregarding the confusion, as you presumed it was nothing, you turned into the alley. Kneeling down to lift the manhole cover, you hop down onto the ladder, pulling the cover back into place. Once you were on your feet in the concrete sewer tunnel, you pulled your hands from your pockets and slid off your scarf as you walked down the tunnel.
 
Black hiking boots thudding against the rock ground, your steps became light once you reached the entrance to the mainroom of the lair. Casually hopping over the abandoned token-taking station, like you always had, your eyes scanned over the area for any signs of Donatello.
 
All lights were off, and the only source of brightness came from the television screen, of which lit up the sight of Mikey completely passed out on the couch. One of his arms hung off the edge of the couch, and he drooled slightly onto the cushion. You giggled softly at the sight.
 
Walking over slowly, you set your bag down by the couch on the floor, and snag the crumbled up blanket at the freckled mutants feet. Whipping the blanket upward, you then watched as it spread out, and you slowly lowered it over the mutant’s body. Mikey subconsciously smiled, and snuggled into the warm fabric that now lay over him. You grin warmly down at him, before walking around the couch in search for your boyfriend.
 
No doubt Donnie had made a break for the lab while you were gone. The purple masked teen had always taken any chance he got to tinker with his inventions, as every moment you were around, he didn’t want to be anywhere else but at your side. You giggled again at the thought.
 
“Donnie,” You chirp, taking a turn into his lab while distracted with removing your gloves. “I’m back. I picked up a can of those coffee beans you love so mu-“ Your breath hitched, and you gasped drastically.
 
The sight was horrifying.
 
You couldn’t see Donnie’s face. Just the back of his head, and a red headed girl with her face smushed against his. Donnie jumped back, leaving a very petrified and vulnerable April. Whipping around, Donnie gulped.
 
“(Y-Y-Y/N!)” He stammers. “W-Wait, please! You-You don’t understand!”
 
It was at that moment when you realized just how Donnie felt, all those months ago, when he saw you with his youngest sibling. Though, you never could have guessed just how withering it was. Just how soul crushing, and heart breaking it was, to see the love of your life with another.
 
“(Y/N),” April suddenly joined in, stepping past Donatello. “Please, don’t be mad at Donnie. It’s my fault. This is all my fault- he didn’t do anything. Please, please, don’t be mad at him. I made a move, and-“
 
“So you kissed my boyfriend?” You say suddenly, all expression vacant from your facial features. April’s lips gaped, as you’d interrupted her, and Donnie stood back with a frantic expression.
 
“W-Well,” She whispers, eyes drooping to the floor. “...Yes.”
 
You nod slightly, looking between Donatello and April. The tension in the room was so thick, it could almost suffocate someone. Both Donnie and April were skittish at your reaction. You were so eerily calm, it made the two of them so uneasy.
 
There was a dreadfully long moment of silence as you silently fought off tears. Your heart swell up to your throat, and your breaths were cut off and frantic. Your nostrils flared, and your hands slightly shook. Though you tried your best to hide it.
 
Finally, you spoke. “I thought you were my friend.” You whisper.
 
April’s head snapped back up at you, eyes wide. That one, simple sentence, just simply split her heart in two.
 
“I-I am-“
 
“Obviously not.” You cut her off again coldly, turning and walking out quickly. You rubbed your eyes stubbornly, determined to allude tears.
 
“(Y/N)!” Donnie cried, walking past April again and dashing out of his lab. He burst into the main room, running over the couch next to where Mikey slept, only to find you’d already gone. Jaw clenched, in a fit of rage, the mutant draws his leg back and kicks the wooden coffee table leg. The leg broke clean off, flying across the room and thudding against the lair wall. Mikey jolted awake, yelping slightly at the sound of the coffee table crashing to the floor afterward.
 
“D, wuh’s goin’ on?” The sleepy mutant slurs, rubbing his eyes and sitting up on the couch.
 
But Donatello didn’t respond. He only put his face in his hands, and sat on the edge of the couch. Everything fell apart, again. 
 
And it was all his fault.
 
It’s always my God damn fault.
 
One Hour Later
 
You paced your living room, one hand over your mouth and the other holding up your arm by your elbow. All the lights were off apart from a small lamp next to your couch, and everyone else in the expanse was asleep.
 
Thankfully.
 
By the time you left the lair, you didn’t care to hold back the endless fit of tears you fought for so long.
 
And you still hadn’t stopped.
 
You kept replaying the image of April with her lips upon Donnie’s in your mind. That haunting sight that you knew would scar you for a lifetime.
 
You couldn’t even contemplate your emotions by this point. Were you mad at Donnie? You didn’t know. Were you hurt? Yes. Were you mad at April? Yes. Were you going to forgive them? You also didn’t know.
 
You just couldn’t organize your thoughts, which is most likely what drove you to your next action.
 
Delirious from rage and hurt, you snatched up your phone and furiously punched in some numbers. Pressing call, you hold the phone up to your ear as you finally halted pacing. You tapped your finger to your elbow impatiently, still trying to steady your frantic breaths.
 
‘What’s up?’ The other line spoke after a moment of ringing. Your breath instantly hitched.
 
You weren’t completely sure what you were doing by this point, or why you were doing it. What exactly was your plan here? Who knew.
 
Your mind was so scrambled with confusion and rage you hardly realized how ridiculous you were being with this so called ‘plan’.
 
Was it motivated by revenge? What were you trying to accomplish? Nothing but one thing was clear to you.
 
There was no turning back now.
 
“Hey, Casey.”
