Its quiet in the lair, just how you and Donnie liked it.
Raph,Leo,and Mikey were at April's to catch up on the Jupiter Jim movies they've been meaning to watch since before the end-of-the-world (almost) happened while Spilnter was out showing Casey around the non-apocalyptic version of New York. So it was just you and him alone and comfy.
The two of you sat on Donnie's bed, you were leaning back into his hard plastron that was somewhat cushioned by the fabric of his hoodie. You two occupied yourself on your phones, mindlessly scrolling as his breath faintly ghosted over your ear, the sensation sending pleasant tingles down your spine.
It felt nice, being in his arms, especially considering he's usally never this cuddly with you, but after about an hour of just laying like that Don started getting really figety, which was pretty uncharacteristic considering he's been no stranger to sitting still for hours working on various projects untill you had to bully him into doing somthing that didn't involve bluelight. You felt him slowly put his phone down on his nearby nightstand, taking a deep breath before leaning forward to pull you closer to him by the waist, burying his face in your shoulder, the sudden closeness making it very easy to feel how warm he was for a cold blooded reptile.Safe to say this was out of the ordinary, hell the ordinary left the building 10 minutes ago, he almost never indicated touch, let alone one that felt so intimate.
"Hm? Donnie did you...need something?" You said softly as you put your phone down in your lap, slightly turning your torso to face him and show you were giving him your full attention. He didn't meet your gaze at first, rather he opted to grumble deep in his throat as if trying to collect himself from whatevers got him so flustered. It took extra time for him to properly put his thoughts into words, especially because he was wasn't the best at verbal communication.
He lifted his head from its hiding place and cleared his throat before reaching into his pocket and pulling somthing small out of his pocket, hesitating for a brief moment then grabbing your hand and placing the mysterious object into your palm. It was smooth and cold at first touch, feeling similar to a metal capsule."Recently you've been complaining that your lips are always dry and that you seem to misplace your chap stick often. I, being the genius that I am, remedied both of these issues via my Genius Built (tm) tech." He paused and let his hand part from yours so you could screw open the tin capsule, which he had graciously taken the time to paint in your favorite color. The inside had a very high quality lip balm inside, the kind you applied to your lips with your fingers, and it smelled just like your favorite fruit.
"Aw Donnie" You started but he cut you off.
"I know you don't typically buy animal tested products but I am a mostly humanoid mutant so there is a morally gray area."
He joked watching as you guided your index finger over the smooth substance and applied it to your lips, gently smacking them to ensure even coverage.
"And applause and applause and waiting for my praise"
You rolled your eyes and snickered at his antics "Well you did solve my issue with chapped lips so.... I suppose that does count for somthing right?"
You gave him a teasing smile and a playful eye roll before your lips met in a soft and gentle kiss. You could tell he really did test the balm on himself, you could taste the fruit on his soft lips.Somhow it tasted even better on him than it did straight out the tin.
After a bit you pulled away from the kiss, reaching for your phone when you felt Donnies hand gently reach out to stop you, his face red and eyebrows scrunched down in a mix of being both embarrassed and flustered.
"Look. I'm not very good at words or convey emotions as Mikey....but" He sighed biting the bullet "I really really,that's two reallys, care about you. I know im not very good at showing it but those are the facts of the matter. And I really want to be a better boyfriend....to you. And, if you are willing, I'd like to take the next steps within our relationship"
Donnie forced himself to look at you to show how serious he was, his grip on your hand tight as he waited for you respond.
"Donnie" You breathed a little taken aback at his display. "I'll only do this if you are completely sure youre comfortable with this. I know youre not very keen on touch and I dont want you to force yourself bassed on my wants. But, if youd have me, I'd be more than happy to..."
Donnie leaned forward to press your foreheads together as you made eye contact. He paused for a moment before reaching one hand up to cup your face, his thumb rubbing your cheek while the other held your other hand, you clutched the lip balm ever so slightly tighter before leaning in for a gentle kiss.
"I wont be very good at it" He muttered against your lips before you cut him off with a kiss.
"I trust you."
"I might get scared halfway through and pull away."
Another kiss.
"We can stop anytime you want."
"I dont want to let you down."
"Donnie." You cut him off, pulling your hand from his to untwist the cap amd rub some lip balm on your pointer and middle fingers which you smeered across his lips to keep him from continuing.
"No more talking. Ok?"
You saw Donnie swallow hard,his Adam's apple bobing as he nodded. Slowly you pulled you pulled your two fingers away, replacing them with your lips as you two kissed in a slow gentle rhythm.
Donnie instinctively grabbed your waist at the contact, trying to insert his tounge into your mouth gently as to not risk potentially hurting you. God he tasted sweet, like strawberry jam, which is probably from the smeared balm that coated his lips.
You straddle his lap, feeling you pants growing tighter as a warm tingling sensation brewed in your gut. Dispite his hands being callous from working with tools over the years his touch was very soft, he even had his nails freshly trimmed and painted, the color matching the one he painted on the tin. He slithered his way down from your waist to the hem of your shirt, lifting it just over your belly before pulling away from the kiss to ask "Can I have permission to take this off?" You took a moment to pant in an attempt to catch your breath from those delicate yet heated kisses "Y-yeah...Yeah.You dont have to ask."
He gently lifted the shirt over your head taking a moment to stair at your bare chest, watching it heave up and down from the effects his kiss had on you. He waited for a moment before gently brushing over one of your sensitive buds muttering "I need to tell you how handsome you are more often than I do". You gasped a little at the unexpected yet completely welcome touch as he grazed his thumb over your sensitive nipples a few more times before pulling away not wanting to overwhelm you, instead he opted to nuzzle his beak into your neck, making soft churning sounds as he gently pecked at and kissed your neck with such high unspoken reverence, you'd think he was kissing a god.
Donnie let your hands creep under his hoodie,lifting it over his head so you could take it off. As soon as his soft skin was revealed you leaned in to pepper small kisses at his collar bone, the sensation making him groan just a little. God you needed him so bad, the bulge in your pants growing so much it was getting too painful to ignore. Donnie noticed this and let his hands fiddled with your belt, helping you pull down your jeans so you were left in your boxers.
Finally you could breath a little.
You rubbed your thumbs over the hem of his shorts (Yes I KNOW they are shadows canonically LEAVE ME BE), your fingertips grazing over the thin fabric as you up to him for approval. He waited a moment before noding sure that he wanted to do this, giving you full consent to reveal the most vulnerable part of him. Slowly, you removed the spandex to reveal his cloaca, already puffy and a little wet from anticipation.
You took a deep breath at the breathtaking sight. It was so hard to believe that he was your boyfriend. After a bit of awe struck stairing you noticed Donnie was flushed with somthing far more intense than embarrassment so you took a deep breath to collect yourself as you hovered a finger just near his heated core, looking up at him for consent which he comfirmed with a nod.
"Let me know if its too much to handle ok?" You muttered as your finger gently ghosted over his slit which was already starting to get sopping wet, teasing the folds which caused him to breath out a whimpery "Please.....". At his beg you gently inserted your middle finger, gently feeling the soft warm walls clentch around your digit.
"Oh oh wow" Donnie moaned as he covered his mouth with his hand "Are you ok?" You asked gently, looking up in concern as his head rolled to the side.
"Yeah its just....a new experience is all."
You gently shoved your finger in deeper into him untill you hit somthing hard and spongy.
"Ive bearly started touching you and yet you're already eager to drop?" You teased softly with a playful smile as you inserted another finger, letting your touch grow more bold as you rubbed against the tip from inside his cloaca a with a little bit more friction.
He gripped the sheets and churred softly.
"Please" he whined "Please...I need to drop so bad....im begging you" he said as he gently grabbed your wrist. While you knew the best thing to do would be to remove your fingers so he could drop you couldn't help but want to indulge yourself just a little, his flushed face and the way his hands gripped the sheets were too much for you to resist. You gently shoved your fingers in a little deeper which made his back arch as he bit the tip of his finger. His eyes were watery from the pleasure.
"Please please oh god I need drop." He begged his grip tightening.
"Shhh you're being doing amazing.Hold on a little longer for me ok?"
He panted and shook his head.
"No im serious, ghn- its too much." As much as you loved seeing Donnie react this was from your touch you cared about his wellbeing far more.
You let your fingers slide out, the feeling followed quickly by a wet noise that indicated Donnie finally unshealthed himself. His length was very long and thick, more than likely a byproduct of him being a genetically modified turtle mutant— wow that sounds weird when you think about but it only makes sense that other aspects along with his physical strength would be amplified. You almost took a moment to thank the angels above at the arousing coincidence.
You were about to grab the lube you always had in your bag for....reasons
... when you remembered that earlier into your relationship that Donnie had mentioned his hatred for anything slimey or that dealt with bodily fluids that weren't contained in a sterile lab, so it would only make sense that the slick from his cloaca could be potential making him uncomfortable, which is the last thing you wanted him to feel during his first time.
You softly kissed his soft lips ,causing him to chirp a bit in suprise, before you stood up "Wait here I'll be right back" you got up and grabbed a few towels for him. Thank God everyone was out of the lair, it be pretty awkward to see your future brother in law walking around your house in his boxers with a hard on so stiff it could cut through diamonds.
You quickly returned with the towels, gently cleaning in-between Donnies legs. And even though the only sound he made was a soft pant you could tell he was deeply grateful. You reached into your bag and grabbed the small bottle of lube you were reaching for earlier.
"Do you know how to prep somone?" You asked as you started taking off your boxers, the sight making donnie shy and turn his head to avert from looking at your privates, he just didn't want to make you uncomfortable but god did he want to see all of you. It was practically written all over his bandana.
"Y-yeah" He stammered opening the lid and pouring some lube onto his fingers. God you loved when it was just you two, he was so adorable. You gently scooted into his lap, holding his face in the palm of your hands and gentle peppering kisses all over his face. He churred at the pleasant feeling, his hands going back to your waist, the lube dripping off of his fingers.
"Donnie" You whispered gently "Look to me" You paused untill he made eye contact with you.
"Don...I want you to look at all of me."
You saw his eyes widened just a bit as you spread your legs encouragingly. After swallowing hard he slowly started to crain his head downward, letting himself see your hard leaking length.
He had to take a moment to gasp breathless at the sight between your legs. How you were so hard from him that he could see every twitch, the fact that that he did this to you, that he brought you so much joy and pleasure you were reduced to a hard aching mess made him uncharacteristically emotional. Donnie was never one to cry, however the thought that he could mean this much to a person was something that threatened to bring a tear to his eye.
He crashed his lips into your, you could taste the love and desperation in each kiss and each grab as he cautiously reached out to stroke you a bit just to see what it felt like which caused you to throw your head back and moan vulgerly from the unexpected touch.
"Dont worry, I'll be gently" He said as he pulled you flushed against his plastron,having you be on your knees so you could hug him while he prepped. You tried to focus on his breaths that made his chest move up and down as he inserted one of his fingers into the tight ring of muscle. The feeling wasn't nessasarly painful but it was really uncomfortable due to how big just one finger was, and you knew at some point he'd have to add the other so you could be able to properly take all of him without getting hurt.
Donnie noticed your grimace and flexed his bicep in front of your face "Here, you can bite on it, I dont mind". You hesitated, but for only a moment before biting down, not harsh enough to draw blood due to his skin being thick but enough to cause him to moan at the pleasure pain.
He gently moved his finger in and out slowly as to not hurt you. He remembered reading somthing about a prostate in his studies of human anatomy during his teen years, supposedly it was somewhat of a "pleasure button" for males located in the anus. He gently felt around untill he found a little bump before pressing on it with only a small amout of pressure though the sensation caused you to bite down harder. Donnie smiled as he found your sensitive spot.
Can't he indulge himself in just a little bit of payback?
He inserted his second finger and thrusted them into your prostate with more pressure than before causing you to cry out.
"Donnie! DonnieDonnieDonnie!" You moaned in pleasure griping onto him for dear life as you forced yourself not to come, you knew youd never live down finishing before Donnie even inserted himself. God. You moaning his name didn't put Donnie far off from coming himself, the sound unexpectedly being music to his ears.
"Donnie please. I'll come im—im gonna fucking come"
Donnie quickly removed his fingers from you causing you to whimper at the sudden emptiness, your hole clenching around nothing as if trying to get the air itself to somehow give you some friction.
"Lay on your back for me ok? A-And let me know if im being too rough; I really dont want to risk hurting you."
You laid on your back as he asked, he very gentle caressed your sides as he very cautiously stuck the tip in.
Dear god. He was so big. He only had the tip in and you already felt like you were being stretched wide open.
"Oh— oh Donnie!" You moaned as he slowly pushed in further. He was so slow and gentle with you, peppering kisses on your neck and collar bone and gently stroking you off to try and distract from the pleasure pain of being stretched open so widely and deeply. He caresed your sides reverently muttering "You're so handsome to me, so so handsome. I love you, I really really do."
God those words. They were more precious than gold, more valuable than raw diamond, more important to you than anything else in the world right now. Donnie was never one to give many complements or "I love you's" due to him not being the emotional type. I mean of course you could always feel the love radiating off him from the small things he did— When he'd let you sit in his lap while he worked, When he'd scoot a little closer to you on the couch, when he loved you to the point of invention. But this. Hearing the words out loud. It was perfect.
Before you knew it all 8 inches were in. You felt so full, like he was reaching the insides of your stomach. You could feel him twitch as he stayed still while burried to the hilt, giving you time to adjust to him while he gently kissed your neck, nuzzling his beak against your pulse point as he breathed in your sent.
After a bit you shakily said "You can- you can move now." He went slowly, only pulling out halfway before pushing back in, the friction your walls created against him was delicious, it felt like he could melt from how hot his body felt being connected so intimatly to yours. Gradually he picked up the pace, just slow enough to make sure you knew he was making love rather than fucking, but just fast enough to make your legs weak as he thrusted directly into your prostate causing you to moan loudly.
Again thank God his brothers wernt home. You two were moaning and grunting ao loud you could swear that astronauts heard you.
Donnie wrapped his arms around your back to hold you close, the room filling with the sound of your bodies connecting and his heavy balls repeatedly slapping your taint untill you couldn't think straight. You felt yourself getting closer and closer to the edge, your nails dragging against donnies soft shell making him whimper.
"Im close! Fuck im so close!"
"I know, Me too!"
Donnie held you close as his thrusts became eradic, he cradeled the back of your head in one hand and held you close with the other.
You cried out as one final slam dead into your prostate was your undoing, your orgasm hitting you harder than a semi truck as thick white ropes painted your stomach and chest and you clamped down hard on Donnies dick. This was Donnies last straw as he burried himself as deep as he could physically go finally coming in you, it felt like his semen was in your stomach as it filled up any remaining room you had left.
He collapsed on top of you and you hugged him close as he kissed your lips softly again and again waiting for you to come out of your haze.
"Are you ok? Did I hurt you?" He panted as you gently caressed his cheek.
"No, you were perfect, so so perfect for me"
He leaned in to kiss you one more time before leaning into your neck, his breath hot against your jugular.
"I love you, very very much."
You smiled as you rubbed his shell.
"I know you do."
You took a moment to lick your lips, savoring the beautiful taste of the lip balm, it tastes even better when it came from Donatello's kisses.
