Masseter Muscle, Mandible, and Mel

Summary:

A month ago is when she happened to catch one Dr. Frank Langdon yawning in the staff lounge as he got ready to pour himself a cup of coffee and promptly understood exactly why some things were considered attractive.

Notes:

I was ruminating on exactly why we have decided as a fandom that Frank Langdon is a... cunning linguist while also thinking about sex through the lens of ADHD leaning towards AuDHD and... Voila. I've used a lot of medical terminology here and a lot of it may not be correct because I've dated several doctors and one of my best friends is a nurse, but I've never needed to know the specifics.

This was also written because I keep seeing people say they see kingdon as something familial and... Families who look at each other like that are why so many stepsisters get stuck in dryers.

Work Text:

Mel had done really well in her Anatomy & Physiology classes in college. Not only had she gotten every question on every quiz, exam, and piece of homework correct, she'd even gotten extra credit a few times for pointing out where a teacher was technically incorrect. (It was really the fault of the diagrams. The supraspinatus and the deltoid were easily identifiable in a full posterior view of the muscular system, but in a tiny black and white sketch that lacked labeling of surrounding details, she supposed a lot of people would remember the general shape rather than a more specific guideline of the angles involved. She had expected more of the TA who had graded the assignments, though.)

As someone who really appreciated the way that all of the systems of the human body worked together, Mel thought she just had a general appreciation of the human figure because it was nice to view a system that worked like it was supposed to. Being a doctor was actually kind of nice for that because it was all about identifying the piece that wasn't working, correcting it, and then watching as the pieces fell into place again.

But, finding a human desirable in a sexual way? It almost felt distasteful in a way. Mel liked to judge people on the choices they made like how they treated staff, whether they picked up after themselves, or if they were nice to children and animals. If it was about appearance, it was only the pieces that they clearly chose for themselves like colored hair, interesting clothing and accessories, tattoos, etc. There weren't all things she would choose for herself, but there was an aesthetic pleasure to be found in seeing someone who felt comfortable in their own body.

At least, that's what Mel thought until about a month ago. A month ago is when she happened to catch one Dr. Frank Langdon yawning in the staff lounge as he got ready to pour himself a cup of coffee and promptly understood exactly why some things were considered attractive.

Now, look, on the surface she understood that Dr. Langdon fit the bill of an attractive man. He looked like he could be someone famous with his floppy hair and needlessly blue eyes, but a sculpted jaw was just a byproduct of genetics... until that yawn that showed how developed his Masseter muscles were. Now, granted, there were so many reasons for that to be the case, but the sight of his teeth didn't make her think that bruxism was the cause, and she didn't notice any general jaw clenching. Since he had a slim, but muscular, build, she didn't think he was someone who generally ate a lot. And there was really only one other thing that worked the jaw so much.

After a few weeks of deep diving into clinical research about sexuality, Mel thought she finally had a handle on why it was happening. While she'd never really thought of herself as asexual, sex was never something that occupied too much of her mind at any given time. When it did, it was almost clinical: apply simulation to the necessary areas until relief is found. But, there was apparently something called demisexuality where one might need to develop a close emotional attachment with someone before sexual thoughts about them could develop. She and Dr. Langdon definitely had the first part going. In all honesty, she'd rarely felt so much comfort with another person, let alone so quickly. So, maybe that accounted for seeing his jaw muscles and immediately wondering what it would feel like to have that jaw worked against her labia and clitoris.

Two weeks of getting caught off guard by little movements he made were really catching up to Mel. He'd grab a chair to pull it out and his flexor digitorum superficialis would flex and she'd find herself biting her lower lip just a little and think of what else he could grip. He'd lean back to avoid an IV bag hitting him and his scrubs would rise up just enough to expose a hint of transverse abdominis and she'd think of the flex of it as he pushed into her. All in all, not the best thing for her mental or cardiac health. But, the only way out was through. A firm rejection might make their friendship awkward for a time being, but certainly no more awkward than it was right now. He was married, and if he chose to try something with her because of what she said just because she seemed easy? That would kill the desire quick enough, too.

As their shift ended for the day, Mel quickly gathered her things from her locker and approached his. "Hey. Look, I know I've been kind of awkward these last few weeks and I wondered if you had a few minutes for me to discuss why."

Dr. Landon immediately said, "Of course! Did you want to go grab boba first and we'll walk around the park?"

Warring with herself for a moment, Mel shook her head. "I think it's more of a private conversation that I prefer to have in a park."

"Sure. Want me to drive you home, then? Or do you need to get Becca?"

Mel shook her head again. "The ride, yes, but Becca? No. She's at the center tonight. They're taking a field trip in the morning to the zoo and she didn't want to chance being late. Apparently they have sensory friendly hours bright and early."

The conversation continued about relatively unimportant things and a general catch-up on the day for the patients they didn't share until they finally got to the vehicle and climbed in. Taking a deep breath, Mel started, "Dr. Langdon-"

"The least you can do is call me Frank. I thought we had something!" He turned the key in the ignition and adjusted the air to cool things down in the vehicle.

"Frank." She took a deep breath and just let it all out. "I've been awkward around you because I suddenly started seeing you as a sexual being and it kind of freaks me out because I don't know how to deal with that." She clasped her hands together and pulled them to her chest, not quite able to look directly at his face, but able to see his sternocleidomastoid flex as he processed her words.

"Mel-" Frank leaned his head down just a bit so she could see the soft smile on his face. "I appreciate you telling me. I had been wondering what I did wrong and why you were afraid to tell me, but I didn't want to try to push you. Is it uncomfortable for you to be attracted to me?"

"It's- it's awkward and a little strange. It helped me discover that I might be demisexual because you're the first person that I've really thought of like this, but I also didn't want to just approach you because you're married and-"

"Whoa." Frank held up his hand and pointed to where a pale band of skin circled his finger where a gold band used to. "You really have been a little checked out, I guess. Mel, I've been divorced for about 2 months and finally took off the ring last week when I realized it might be sending the wrong message."

Mel let her hands drop to her lap. "Why didn't you tell me? I would've been happy to help you process all of that."

"This is going to sound terrible at first, but let me explain. You were the last person who was going to help the situation. It's not because of your abilities to make me feel better or anything, but in a tiny way, you're part of why I'm divorced, and I should honestly thank you for that." Frank reached up and ran his fingers through his hair, looking like he was still thinking about what to say next when she got there first.

"I'm why you got divorced? That's terrible! I would never want to cause something like that."

Frank held up one hand. "Let me explain. In the wake of being suspended, Abby and I spent a lot of time at home together and I realized that we don't actually have anything in common other than our kids so we never have a great conversation like you and I can about virtually anything. The more I thought about it, the more I realized that we never could. Then, when Abby threatened to divorce me because of what I did, it really got me thinking about what that would mean. Where I'm from, there are a lot of couples that stay together for the kids, but their kids are never happy about it. I would rather Tanner and Penny understand that if a situation doesn't make them happy, then they can leave it." He shrugged, letting the fingers of one hand trace against the rim of the steering wheel. "Abby and I came to an accord about it after we talked it out over the course of a few days of mediation. We both kept confusing loving our children with loving each other and it wasn't fair to anyone."

"I'm sorry." Mel looked at his hand on the steering wheel, the abductor pollicis brevis flexing gently. "I'm still a little upset that you didn't tell me, but it feels really selfish. I was going into this conversation expecting you to shut me down immediately so I could just get over it, but you're not doing that and I don't really understand why."

Frank's hand that wasn't on the steering wheel reached over to gently grasp her own. "Because I have no interest in shutting it down."

"Honestly, I think this was the only potential outcome that I didn't prepare for." Mel watched their fingers entwine like an outsider, barely feeling the touch because of the shock of it all.

"When you said you started seeing me as a sexual being... Can you give me a few examples?"

His words don't help the shock which let's her mouth speak before her brain can second guess itself. "Your Masseter muscles make me think that you're incredibly gifted at oral sex and I imagine your arms manhandling me in a variety of ways." Her brain kick-starts enough to seal her lips, her eyes going wide as she looks up to meet his eyes.

"Oh, sweetheart." Frank's thumb strokes along the back of her hand and she watches his thenar web space fold and unfold. "I'm not doing a great job of explaining myself, am I?" He reached his other hand over so that both of his were grasping hers. "I have had a growing infatuation with you for a while now. It didn't end my marriage, but once my marriage was over, I let myself think about it more. I was keeping my ring on once I was divorced because women didn't bother me, but then I realized that you weren't bothering me any more and I think I would do literally anything to get your attention. And if that means showing you exactly how good I am at eating you out? I'm down."

Mel sucked her lower lip into her mouth to bite it gently as she felt her face heating up at his words. "I would like that."

Frank let go with one of his hands. "Do you want to go to your place or mine? I figure now is as good a time as any."

"Yours. I assume, since you're divorced now, you have your own place?" Mel let her own fingers trace his flexor tendons and then rest above his scaphoid.

"It's very bachelor pad with additional rooms for the kids when I've got them, but the bed is incredibly comfortable. It turns out you can get insurance to cover part of a good mattress when you have enough back issues." He laughed sardonically and glanced down at his hand grasped in hers, then awkwardly situated himself to put the car into reverse using his left hand. "I know you're thinking that you could just let go of my hand, but that's not my preference right now."

Somehow, that made it easy to hold onto his hand a little tighter, but then the evening's sun kept catching along the planes of his face and highlighting his jaw and she squirmed in the seat a bit. Frank seemed to notice and let his hand rest heavier against her before licking his lips lightly. She squirmed a bit more, but also felt herself pulling his hand a little lower and closer until it was nearly against her mons pubis. Watching Frank smirk from this vantage point was a treat. The cleft dimple in his chin was always visible, but the smirk brought another to whichever cheek he raised in amusement. Though it was only an anomaly in the zygomaticus major muscle, she couldn't deny that there was an attractiveness to it when it was on him. Just as her gaze moved to tracing along his straight nose, he pushed his hand lower and made contact with her jeans and she let out a soft groan. "Dr. Lang- I mean, Frank..."

He kept his hand still as he drove, his eyes on the road and other hand glued to the steering wheel. "Is this okay?"

She nodded and forced out a noise to the affirmative. "Are we very far?"

He laughed softly and gestured with his chin outside of the vehicle as he leaned over again to shift into park. "I'll need my hands back for just a little bit, but then they're all yours. My mouth, too."

Her face burned again as she let his fingers slide away, quickly shucking her seat belt and grabbing her bag in order to follow him. There was someone else riding the elevator with them so she was denied the contact that was so close until they reached his door and he pulled her towards him and leaned into her, his lips catching her own and his depressor labii inferioris working in tandem with his mentalis to give her a preview of what to expect when they were inside. The door opened behind them and she took a moment to prepare herself for what was to come if he could kiss her like *that* while simultaneously unlocking a door.

He pulled her inside gently, then gestured to the couch. "The couch is there if you just want to sit and talk more." Then he gestured behind him to a door that suddenly seemed to loom larger than life. "Or we can go directly to the bedroom. It's up to you."

Until that moment, Mel would never have called herself brave. Most other people wouldn't have applied the label to her either. But, when the choice was to use Frank's mouth for talking or the thing that had taken over her mind for weeks, it didn't feel like bravery at all but a foregone conclusion. She marched to his door and opened it, walking through with a shiver down her spine. She dropped her bag at the end of his Tempur-Pedic and unzipped her light jacket to let it fall to the ground as she toed at her shoes. "Well?"

He was in the room in half a second, already pulling off whatever his hands could reach on himself until he stood there in front of her in just boxers and socks, his hair a mess as he approached her and let his fingers grip the bottom of her t-shirt. "May I?"

"Please." She let him peel the shirt up and off, dropping it to the ground as he stepped forward to press his lips against the tops of her breasts, his fingers gently cupping the outside of her bra as his tongue laved against the skin under his lips. She would have sworn that she wouldn't have liked the sensation, but as humans lacked hygroreceptors, it didn't feel wet, but just warm and heavy and right.

Mel let her hands come up to trace the muscles of his back as he leaned over her, the trapezius and latissimus dorsi sinuous and lean, the deltoids filling her palms as he reached around to unhook her bra and pull it down her shoulders. He took a moment to stand to look at her and sighed in rapture. "You're beautiful," he whispered as he caught her eyes again. "I should have told you that before I took your bra off, but I couldn't let the moment pass by. Are you still comfortable?"

The bravery kicked in and had her undoing the button and zip of her jeans and pulling them down with her panties so they fell to the ground and she could step out of them towards the bed and sit at the edge. "I feel beautiful when you look at me."

He let out the tiniest hint of laugh as his nostrils flared. "Mel King, I think you're going to be the death of me after a very long and happy life." And then he pressed her back on the bed and pulled one leg up over his shoulder. "Say 'red' if you want me to stop. If you can't speak, tap my shoulder three times." He started to lean towards her pelvis again, but paused. "You can absolutely pull my hair." And, with that, he dove in.

Mel had had lovers in the past claim they were talented in this area. Some of them definitely had a fair amount of enthusiasm, but there was nothing about any of those encounters that made her do anything she'd call an orgasm. This? This was different. If cunnilingus were an Olympic sport, Frank Langdon would put Michael Phelps' gold medals to shame. He didn't just eat, he devoured.

So many men who performed oral sex used their tongue and maybe their lips, but Frank was an overachiever. His tongue was used to lick flat against her vaginal opening, to delve between her labia, to flick against her clitoral hood... But that was barely the start of things. His lips closed around her as he sucked at her clitoris. His fingers pressed within her, holding her open for him to press his face further inside. His teeth dragged against places that swelled with arousal in response. But, the place where Frank went above and beyond was that he wasn't afraid to nudge against her clit with his nose and lick into her as his chin pressed hard against her fourchette making her feel wide open for everything he was giving her.

The entire time, she couldn't look away. She started with her hands beside her, clutching at the bedspread and trying not to let her eyes roll back in her head, but she had to let her hands come up to stroke against his shoulders and up his neck until they were buried in his hair. At one point, she marveled at the juxtaposition of gently pulling back a few strands of hair from his face as he almost furiously consumed her. Then, he bit down on her clit and nearly drove his chin inside of her, the edges of his mandible stretching her with a delicious ache. Her fingers tightened in his hair as her entire body seemed to curl with pleasure from her back to the arches of her feet. Her thighs trembled and clenched around his head, holding him in place as she felt herself gush around him.

A moment later, her legs fell back apart as she struggled to catch her breath and pull her fingers from Frank's hair without injuring him further. "You are... Incredibly good at that."

Frank crawled up the bed beside her, grabbing a corner of the bedsheet to wipe his thoroughly drenched face dry, then turned to her with a grin. "Everything you dreamed of?"

"In all honesty," Mel said as she struggled to turn over onto her side, "That was so far beyond anything I thought I could feel. I've had other people perform oral sex on me before and it was nice, but in the way that a cupcake is nice or a sunny day with a little breeze is nice. This... I think it was life changing. I've never actually come from oral before and you made me squirt which is a rare enough thing on its own. So, new things all around."

Frank laughed softly and moved closer to her so that she could see that he still glistened in his nasolabial folds and the cleft of his chin. A part of her wanted to be embarrassed by it, but Frank looked so proud of himself in that moment that it was hard not to be caught up in the joy. "Sweetheart, I think you've just been with people who were only concerned about their own orgasms because your body is like a Stradivarius. It takes a great musician to bring out what it can do."

Mel curled up a little and looked at him, feeling a warmth wash over her that no longer seemed to be coming from her desire for him. "I want to make you feel good, too."

Frank shook his head. "You don't have to. Tonight was about you, and I did really enjoy what I was doing."

Mel cleared her throat a bit. "And if I were to tell you that I generally need two or three orgasms before I feel like I'm done? I certainly don't want you getting TMJ disorder and I definitely had other fantasies about you."

"I just don't want to scare you off." Frank slid his thumbs under the waistband of his boxers. "Let's just say there was a reason I had so much opportunity to practice eating girls out." He slowly started to pull the waistband down, keeping eye contact with Mel all the while.

"It doesn't need to be some certain size or anything, Frank. Whatever you've got, I'm sure-" Her words cut off as his waistband slipped down the underside of his shaft, holding it aloft. "Oh." While she had initially thought he might be like quite a few men who thought their penis size was inadequate, Frank clearly had the opposite problem. While it was hardly something out of a fetish porn, it was definitely larger than average with quite a bit of girth. Without thinking much about, she got up on her hands and knees and wrapped her hand around him, her fingers sliding in his precum and pulling a grunt from him. "Frank, I think you were made for me."

He looked dazed for a moment. "What?"

She grinned and let her hand start to stroke him again. "I have ADHD. Sex gives me dopamine, but like all things that produce dopamine, it can wane with time, so I'm always searching for other things that can bring back that same high. It doesn't happen all that often as I have tended to have a relatively low libido, but I fear that with you around I won't have as much of an issue there so I may request we try some things at times. But, ah, all of that was to say that I do enjoy some significant penetration and think we'll be very compatible. Do you have condoms?"

Patting his way towards the nightstand with one hand so he could keep his eyes locked on Mel, Frank couldn't stop smiling. "Mel, there's no one else I'd like to try new things with.” He pulled a condom from a box in the nightstand drawer and dropped it on his stomach.

With precision, Mel tore the packet open and slid the condom down his length with gusto. "Do you mind if I'm on top? It will help me worry less about your back."

"I'm yours however you want me." Frank leaned back against his pillow and watched Mel as she straddled him, situating his glans against her entrance and sliding down until he was fully within her with his tip just pressing against her cervix. "Good?"

Starting to move her hips so that he slid within her, Mel nodded. "You can touch me. I would prefer you didn't pull my hair, though. You can slap my breasts if you'd like. Or squeeze them."

Frank lifted his hands to her chest, one hand cupping each breast and each thumb treating her nipples like joysticks for a moment as she rode him until he finally pinched her nipples with enough force that her burgeoning rhythm faltered. She murmured her approval before leaning over him to change the angle, letting her vaginal walls clutch against him as she continued her slide, never moving so much that he might slip from within her even as he brought his knees up so he could plant his feet against the bed for more leverage. "Mel, sweetheart, I'm not going to last long if you keep doing that."

Mel ignored him. "I won't need you to." She upped her pace slightly, really focusing on how she could feel him practically throbbing inside of her. Her breaths were getting high and tight as she leaned over him more only to have him lift his head to surround one nipple with wet heat and just a scrape of teeth while the other benefitted from the pinch on his fingers. Just when she thought she was as ready to come as she could be, the remaining hand came down and pressed at her clitoris in such a way that every movement she took reminded her of the flick of his tongue. In that moment, Frank lifted his hips and thrust into her from below as he cried out, each thrust pushing his thumb against her clitoris even harder until she came again with a shout and sat atop him until her thighs stopped trembling and Frank's breathing slowed beneath her. When she went to slide off of him, the condom started to stay in her, but she managed to save it at the last moment and then collapse on the bed beside him. "I already knew we were mentally compatible, but this is an incredibly pleasant surprise."

Frank ran a hand down her side and chuckled softly. "If I thought fate were real, I'd definitely be praying or something right now."

"I think you already spent enough time on your knees." Mel shivered suddenly, her eyes rolling back slightly. "Oh, it's been a long time since I orgasmed so well it had aftershocks."

Frank kept his hand on her side. "What do you need? I've got water, snacks, clean sheets, extra clothes..."

Mel grinned. "I'm going to go to the bathroom because I don't want a UTI while you change the sheets and then I want to go to sleep. But, like, just close and not actually touching it that's okay."

"There are extra toothbrushes in the drawer to the right of the sink. You can just put it next to mine for next time you're over... If I'm not being presumptuous."

Standing up and feeling a bit like a newly born fawn with wobbly legs, Mel started to make her way to the en suite to clean up. "You're no more presumptuous than I am in this case." When she came back out, there were new sheets on the bed and a different bedspread ready to be placed on top. Mel helped Frank with the last step and crawled under the covers on the side opposite where the condoms had been. "Should I wake you up if I get horny in the middle of the night or would you prefer I take care of it myself?"

"Does that happen a lot?" Frank slid under the covers on the other side, laying down with the pillow wedged between his arm and head so he could look at Mel.

"I wouldn't say it's regularly, but it happens often enough and I couldn't say why. Sometimes it's when I've had very good sex and sometimes it's when it's very bad. I assume it's just the hypersexuality component of my ADHD. I do also have periods of virtually no libido, though, to make that clear." Mel shrugged. "So, wake up or not?"

Frank nodded once. "Absolutely wake up, but I'm also happy to just watch if that's a thing you enjoy."

"Surprisingly not a thing I've spent much time thinking about, but I look forward to trying it with you." She moved around until she was comfortable, her body throbbing in so many areas to remind her of what they'd just done. "Hey, Frank?"

"Yeah, Mel?"

"I'm really glad we actually talked today. And not just for the sex. But, again, the sex was phenomenal and I'm looking forward to more at some point when I'm not exhausted." She nuzzled into her pillow and sighed contentedly.

"I had actually started to wonder if you were asexual because you weren't reacting to my flirting and I was doing research about that to figure out what that might mean for us." Frank reached down to grab her hand, pulling it up to kiss her knuckles. "When you have those times when you're just not interested in sex, I'm prepared for that."

Mel froze for a moment under his gaze, just watching him treat her gently. "You make me feel seen."

Frank let her hand go in order to reach across the bed and gently pull her glasses from her face, folding them and putting them on his nightstand. "Seen is a very good way of putting it." He paused. "And I'll see you in the morning." He hit a switch on the lamp to plunge the room into darkness.

"Unless I wake you up to watch me masturbate."

"I don't think I'm actually going to get to sleep with that thought in my head, y'know."

Mel laughed and let her leg brush his under the covers. "You'll be fine. Doctor's orders or something."

While she couldn't quite see his eyes close without her glasses on, she could hear his breathing start to slow a moment later just as the adrenaline started to process through her body leaving her suddenly exhausted. With one last glance to Frank's jawline in the light of the various chargers by the bed, Mel curled up beside him and let sleep take her.
