Nothing Left Hidden

Summary:

The dip of William's petite build into his narrowed waist makes the lump bob in Mark's throat, the man licking his lips and forcefully dragging his gaze back up to William's. "Do you- uh- do you want-" the stutter is cut off by William's grin and raised eyebrow.

William couldn't be more excited and it shows in the way he squeezes Mark's shoulders and eyes Mark's covered crotch for a minute. As if he could see through the grey sweatpants. Meeting Mark's eyes William leans a little closer. "Do I want to have sex? Yes."

• Markwill •

The wet sound of tongues sliding together and the rustle of sheets fills Mark's bedroom, only battled by the panting and soft moans of the men sitting in the middle of Mark's bed. The Grayson household is otherwise empty, Debbie going on a small vacation for the weekend. She'd offered for Mark to come but a knowing gleam on her eyes told Mark she knew his answer before he mumbled out the stuttered "N-no thanks, mom, I'm good, lots of homework and stuff, y'know-" while his brain immediately jumped to being able to invite William over. 

"Yeah, yeah, I'm not stupid, kid. Just remember to be protected, stay safe, even though pregnancy isn't an issue okay?"

"Mom!" Mark had groaned only making Debbie grin in amusement

"No glove, no love." She reminded him, somehow serious yet clearly enjoying the situation. 

Mark already had covered his ears by the time she finished, trying to curb the intense embarrassment that washed through him. "Mom, please!

She'd smiled and tried to ruffle his hair before Mark ducked out of the way and escaped to his room. 

William came over later that day, saying goodbye to Debbie on her way out. And when Debbie called out for them to stay safe again, they both blushed while Mark vocalized his despair. "Bye, mom! See you later! Please go!" 

William still giggled through Mark's suffering. 

They'd watched a movie for a while before making their way up to the bedroom, William announcing that he had to shower before the grime solidified into his pores. Mark had spent the entire time sitting on the corner of his bed, knees bouncing while wondering; would this weekend be the time? What's the harm in asking, at least, it's not like William would be angry or grossed out. Mark's just filled with a sense of anxiety knowing that William's long since had sex with a guy before, where as Mark's only been with Amber. But they're both grown men, if Mark can't even just ask William if he's ready to have sex then he might as well throw the whole adult card away. 

So the question laid heavy on Mark's mind and while he hadn't intended to turn the mood in a more sensual direction, William is the one who chose to walk out in nothing but his boxers. The smell of his own body wash lingering on William's body turning a sort of possessive arousal in Mark's stomach, he'd reached out and pulled William onto the bed with a kiss to his head, murmuring "You smell good.." 

The ensuing makeout lasts for a while before Mark pulls away with an audible swallow, glancing down at William's body which is freshly pink and soft from the recent shower. His hand caresses over the smaller male's side, feathering over the feeling of ribs while the other hand rubs a thumb over William's hip. The dip of William's petite build into his narrowed waist makes the lump bob in Mark's throat, the man licking his lips and forcefully dragging his gaze back up to William's. "Do you- uh- do you want-" the stutter is cut off by William's grin and raised eyebrow. 

William couldn't be more excited and it shows in the way he squeezes Mark's shoulders and eyes Mark's covered crotch for a minute. As if he could see through the grey sweatpants. Meeting Mark's eyes William leans a little closer. "Do I want to have sex? Yes." He assures his nervous boyfriend. And Mark can't but sputter and cough with William's forward nature even if he's used to it by now. It still catches Mark off guard sometimes and he laughs, 

"Wow, I wasn't sure if you were ready or not-" 

Loving Mark is something that William never realized he was even doing until much later in his life, loving Mark is second nature- which came hand in hand with waiting for him. And william has waited for Mark his entire life. William waited for Mark to come save him as children playing heroes, William always the civilian in need of saving with loose, poorly tied rope looped around his arms.

He'd waited for Mark to come back to him after they lost Rick, after Mark and Amber broke up, waited for him after Mark's father turned in the worst possible way. Waiting for Mark is something William is familiar with. So being ready for him is just another inherent fact for William by this point, more than ready- William had again been waiting. Dutiful, happy, and patient. 

William shakes his head with a chuckle of his own, sliding his arms around Mark's shoulders now. "Mark, you were the star of my first wet dream. You basically kicked off my gay panic." 

Mark rolls his eyes in a playful manner while a blush starts to spread across his cheeks. "Oh, so no pressure or anything then. I don't know if I'll live up to expectations." It's well humored but William can tell there's a reaction of worry there, Mark always wanted to live up to people's expectations, to be the person he thought he needed to be for them. Mark took the expectations placed upon him and latched on like it were his gospel. William's been trying so hard to help Mark understand that he's always been good enough, just as he was. 

So William quickly pecks Mark with a smile against his mouth, hoping to dispel any worries with his go to humor. "Who said anything about expectations? Don't worry, babe. You're the half virgin here." 

William's joke spins around in Mark's head momentarily before he pulls away enough to tilt his head with a confused look, all the worry gone much to William's happiness. "Half virgin?" 

William nods. "Yeah, you don't have any experience with guys yet so you're a half virgin, unless.. you didn't with any girls-" he starts to end the question with a teasing tone that makes Mark shake his head quickly.

"No, I'm definitely only a half virgin." The man pauses as a sudden thought crosses him. If Mark is a half virgin, which is definitely not how that works in the first place, then- "Wait, wouldn't that make you a half virgin too? Cause you've only been with guys, unless you've-" his eyebrows raise quickly, imagining William and a woman together.

Now it's William's turn to be embarrassed, even waving his hands in an emphasizing gesture. "No, I haven't, so yes I am but it's not applicable in this situation so we're moving on." William clears his throat and gives a slow clap. "Congratulations, I'm so proud of you. Hopefully no little Mark's running around." 

With a resolute shake of his head Mark says "Absolutely not, no glove no love." His mouth pulls into a lascivious grin and despite parroting his mother's sentiment, wiggles his eyebrows. "buuut.. we don't have to worry about that.." 

William's eyebrows raise in surprise at Mark's courage or perhaps ignorance. "Uh, excuse me, did you pay attention during sex ed or only when they had the drawings of boobs out?" Each std gets its own finger as William starts to recite, "Stds; HIV, hepatitis, gonorr-" 

Mark gives William an amused and pointed look to help cut off what would be a long list from the soon to be med student. "Do you have any of those?" 

"What? No!" 

The grin is back. "Well neither do I." William rolls his eyes and pulls him close to press a loving kiss against Mark's lips for a long moment, William's fingers lightly petting the baby hairs on the back of Mark's neck. 

William's voice is breathy now when he pulls away, murmuring with a sexy smile. "You're lucky I already want to do it bare." William smiles with a brilliant red blush across his cheeks, a little flustered. "Otherwise you'd be pushing your luck, Grayson." And Mark suddenly felt more aware of his heart picking up a faster beat, thumping heavy in his chest.

"Oh yeah?" The hero moves to kiss up William's neck, ending at his jaw that Mark nuzzles. "I'm already in bed with the only guy I've ever wanted who happens to be my best friend too, about to lose the other half of my virginity-" he chuckles "I'm not sure how I could get luckier than that." 

William kisses Mark deeply. "I'll show you, you haven't even gotten lucky yet." He grins and pushes his boyfriend back into a sitting position on the bed. "Off." William tugs at the fabrics covering his boyfriend and helps Mark remove them before he easily straddles him. 

Mark nods, a little awed at William's action but certainly appreciative as he eyes his boyfriend's nearly bare figure. "Show me, baby." The hero licks his lips when they suddenly feel dry, William's ass slots perfectly between Mark's thighs- Mark's always loved the petite frame of william. He fits so perfectly in Mark's hands, like he was made to be held and adored. Appreciative hands run over the expanse of William's chest, lightly brushing the pink buds on their way. The little sound he makes in response has Mark's dick twitching against his lower stomach. 

They fall into an easy makeout, William's hand eventually sliding down Mark's chest to take a hold of his member. "Mm, you're so hard already and you're leaking." The giggles dripped with mischief as William pressed on the tip, circling his thumb over the slit.

" Ha- " Mark's inhale with a sharp sound, back straightening up. He squeezes William's hips. "can't help it when you're just wearing boxers and touching me like this-"

William strokes up and down Mark's length, slightly twisting his hand to get Mark's balls twitching. "You're that easy?" The teasing expression causes Mark to pout. 

"We make out like every other day since we got together." Mark points out, defending his own easiness when William was definitely handsy in his own right.

William tilts his head and raises an eyebrow. "I haven't heard you complaining. But I can stop-" 

Mark squeezes William's hips again to better cut off his boyfriend. "And I'm not! Definitely not! Just saying, who's easy here?" 

"Still you but also me too. So it looks like we're easy for each other." William hums with a soft smile, leaning forward to kiss the corner of Mark's mouth. 

Mark slides one hand back, dragging William's boxers with them so he has access to some of the smooth curves. "I hope you're only easy for me." William blushes and pushes his ass back into Mark's hand who gropes with a greedy squeeze in response. 

"But you know I like it when you get jealous." William moves back on Mark's lap enough to see his hardening cock, squeezing the base of it like Mark squeezes his ass. The breathy moan mixes with a slight laugh, the familiar brown gaze darkening with lust as they flicker between William's fingers and face. 

"I like it when you squeeze me like that." Mark murmurs, voice thicker than before in a way that stirs warmth and excitement in William's stomach. He uses his other hand to curl under Mark and lightly fondle his balls, his boyfriend's body trembling through a full body shudder. 

"And like this?" William already knows the answer but the point is to hear it. And hear it he does. 

"Yes!" Mark nods quickly, barely managing to keep his grip from accidentally bruising William's thin hips. Full Viltrumite strength would be no match for the soft, human curves. So Mark keeps himself in check, even though the want for William is only building. "Fuck, yeah." He nods. 

William smirks, sliding off of Mark's lap entirely and getting on his knees. "And how about when I do.. this?" He starts to slide down between Mark's legs who sucks in an excited breath, his dick twitching the closer William's face approaches it. Wet sounds of William's tongue and mouth working on him fill the room, Mark exhaling shaky and shuddering.

His head lolls back for a second from the feeling of the warm tongue curling around his tip, flicking against a strong vein on the underside of him- "Sshit!" Mark groans, barely keeping his hips from bucking like they twitch to. "Y-yeah- wow. How are you doing that with your, mm, tongue?" 

The wet sucking behind Mark's breathy question stops when William pulls off, licking a lewd smirk on his lips. "Do you want me to stop and tell you?" 

"No!" Mark blushes in embarrassment at his frantic statement, voice a little more restrained when he asks again but is still begging- "Please, don't stop." 

William giggles and kisses the flushed tip, licking it with a soft moan. "Hmm, I didn't think so. Now lay back and enjoy, babe." a wink seals his push, William sticking his tongue out and licking up Mark's cock like a popsicle. Taking the head in his mouth once his tongue reaches the tip, William hallows his cheeks before descending down to the root in a quick move. There's only a semi regret when William gags a bit, but he relaxes his body and swallows around the thick length, staying on it.

Mark, more or less, falls apart. One hand curls into the fabric of the sheets with all the strength he has, forcing the other hand on William's head to stay gentle. His toes curl with the effort to stay still and not buck his throbbing dick into the flex of William's throat. It's like a fluttering, extremely wet suction on Mark that's lighting a fire through all the cells in his body. "Ah, William! Holy shit! S-slow down, baby, don't hurt yourself.." Mark pants a bit, soft yet a little labored. 

The throat works around the length, giving an obscene slurp when William pulls off and gasps for a breath then takes it back in. Mark knew William had experience but this is making him feel absolutely virgin like, as if this is the first time he's ever been touched. A warm fuzz is descending through Mark's brain and the more he watches William suckle his dick the more he just can't think

It's nearly a blessing when William finally frees Mark's cock from his torturous mouth, a wet pop following his release. "Oh god.." Mark sighes, hips jerking into the air in an effort for more friction. But Mark just feels relieved that he managed not to cum prematurely. 

Wiliam's pushing the blue boxers down his narrow hips, giving Mark a full view of William's pink and wet dick. A long string of pre cum slips down the shaft and Mark suddenly feels thirsty. 

Under the intense gaze of his boyfriend an embarrassed pink blush starts to dust across William's pale skin. "Where's the lube?" He barely finishes the question before Mark has launched off the bed. He hovers while rooting through the bedside table, returning to the bed quickly. But before William can take it and squeeze any onto his fingers, Mark shakes his head. 

"No wait, I want to do it.. can I? Tell me what to do." The puppy dog look Mark gives while nuzzling William onto his back is more than enough to convince William, but the needy tone is definitely the cherry on top. 

He smiles and nods, spreading his legs to give Mark access to the small, pink hole. "Start with one finger and rub some lube on me first." Mark doesn't waste time, clearly excited to please and also anxious to start. William gasps a little at the sudden intrusion, easing the sudden worried pinch in Mark's eyebrows. "Cold." He chuckles. 

Mark grins and leans down to kiss William, full of love but also licking at his lips before pulling away enough to breathe, "I'll warm you up."

William nods, stretching his arms above his head. "Mmm, now push it in and out-" A hitched moan breaks up his instructions

 "Yeah, just like that, Mark." One hand reaches down to pet Mark's hair while William praises his lover. 

Mark nods with a pink, pleased blush. He works the finger in and out of William's hole, staring at the way the hole swallows the digit "You're so warm. And tight." Mark whispers in a little awe, pausing to wiggle his finger slightly. William shudders and giggles, flexing his hole around Mark's finger. 

"Now imagine that around your dick." The tease is of course paired with the classic raised brow and playful grin. Mark swallows audibly around a sudden lump in his throat, his imagination strong enough to envision the tight, phantom heat. His dick visibly twitches and William laughs. Mark resumes the movement of his finger and makes William whimper. "Wait, to the left a little, press-" 

Mark stills the finger before pointing it a little more left then pressing down on a little feeling of what must be William's prostate. "Here?" 

The man shudders with a broken moan, hand tightening in Mark's hair momentarily before smoothing over the locks. "A-aah~ yes, right there."Mark thrusts his finger against the bundle of nerves to draw another shaken whine from William. "Nn, Mark, add another." 

Mark nods, sliding another finger into William who accepts Mark with barely any resistance. "You're so hot, William. You look so good like this." The voice is thick with need and appreciation of the naked body squirming on his fingers, Mark's hungry eyes raking over every inch of William he can. 

"You're making me feel good, your fingers- ah, so nice- harder." William begs, pulling his legs up and pressing his hips down onto Mark's hand. 

Mark picks up his pace but still holds back strength, not wanting to spear William. "Like that, baby?" But he makes sure to rub the fingers down on William's prostate and thrust them harder than before. 

Fast nods assure Mark that he's doing just fine, as well as William higher pitched whines. "Mmhm! Mark!" William bites his lower lip, sultry gaze meeting Mark's eyes. "S-spread your fingers a little and open me up, get me ready for your cock."

"Oh Jesus Christ." Mark's the one who gasps now, leaning close to kiss William then along his neck to hide his blush. "You're so dirty." William's always been forthright but it still sends a shoot of heat through his dick. He complies though, biting his inner cheek at the feeling of William's asshole spreading on his fingers. 

William hums, eyeing Mark's cock that hangs in the air between his muscular thighs. "You like it, I can see you twitching." Thick, long, flushed and wet at the head with his precum- William needs it.

"I really like it." Mark tries to wet his dry, hungry mouth while fingering William open. "Have you done this to yourself and thought about me?" The question immediately rolls off his tongue the second Mark thinks of it, but he doesn't regret asking when that gorgeous scarlet crosses William's cheeks. 

He nods, whining and rocking onto Mark's curling fingers. "Yes, you're so hot, Mark. I started doing it even more once we were dating, I get so hard thinking about you-" Mark can't fight the need to taste William's lewd talking tongue. 

Mark releases William's mouth and breaks a string of saliva between their lips. "You don't have to do that anymore. I'll give you the real thing anytime, baby." Mark promises with another kiss, quicker but just as passionate. William's fingers have moved to pull Mark's head close, fingers petting over Mark's scalp and disrupting the gelled hair. 

"Then you can start by giving it to me now." William demands once their mouths separate again.

"Heh, bossy." Mark chides with humor, scissoring the digits for a second just to make William whine. 

He nods instead of throwing something back at Mark which, alone, tells Mark how bad he wants it. But to clear any potential confusion, William grinds his hips against Mark's fingers with a tight flex."And needy for you. I want you inside me, Mark.. spreading me open." The chime-like moan is the cutest thing Mark's ever heard. "I want to feel your hot cum filling me up-"

William's dirty confession is paused when Mark kisses those perfect lips fiercely and presses him against the bed. "Jesus, William. I want to feel you too, as deep as I can. I need to feel you, baby." 

Blue meets brown, both reflecting an equal depth of tender love and understanding. "I'm yours." Whispers the dirty blonde, caressing Mark's neck and making the brunette smile.

"And I'm yours." Mark had been the whole time, he just didn't realize it until later. 

Their foreheads meet, nuzzling together. "We make a good team."

Mark can't help but grin with the sheer, pulsing amount of happiness in his chest. His best friend, his boyfriend, his personal teammate, William always stood by Mark- even when Mark didn't quite deserve it. But Mark strives to be the man William sees and praises so constantly. Lately though, it's getting easier to believe that maybe, Mark always has been. Faults and all, just like William says. "Always." 

They really aren't about to fuck and as cliché as it is, it is on the truest sense- making love. 

"Give me the lube, I want to touch you, babe." William pants between kisses and takes the lube when Mark hands it, stroking the hero's cock once he coated his palm. Mark groans and gives two loose bucks into William's grip while helping William lay back. They both spread William's pale, slim thighs together. "Go slowly at first, not like a snail or anything, I may have flawless porcelain skin but I'm not a doll." William reminds with a small, cheeky grin. 

It helps ease Mark's heart a little which pounds in a mix of excitement, anticipation, and nerves. He's not scared, he just wants to make sure this is good for William. He wants to be as good as William's already had and Mark wants to show every ounce of love he has to give. But he also doesn't want to hurt William. Soft, sweet William who would break so easily if Mark accidentally slipped up. "Just tell me if I'm hurting you, okay? Promise?" Mark almost pleads, eyebrows furrowed slightly. 

William's smile reflects only a little bit of sadness, catching the spark of anxiety in his lover's gaze. "I promise." Soft fingers curl around Mark's cheek, caressing it. "But I trust you, Mark. Don't forget that, okay? And don't you trust me?" Sometimes he needed the reminder, he needed to have a supporter against any self doubt. 

Mark nods and smiles softly as relief and love pours through him. "Yeah. I do."

"So trust that, too. I always believe in you." William's faith in Mark never needed powers, they never needed a suit or heroic efforts. Mark has always been enough, just as he came and William would never stop reminding him of that. He reached between his legs with one hand, helping press the tip of Mark's dick into William's wet hole. "Make love to me, Mark." William whispers while closing his eyes, too lost in the feeling of Mark's hot cockhead breaching him to even realize what he'd said. 

"Ah- shit, shit- holy shit William so tight-" Mark gasps in shocked pleasure, not expecting William's ass to grip him tighter than anything he'd ever felt, even his own desperate hand. His hips press in slowly, opening William up and allowing Mark inside. 

William whines and sucks in a shaky breath, fingers curling around Mark's shoulders. An arch builds in his back while William's toes curl. "You're big, Mark, nngg~" He whimpers. "You're ss-spreading me open-" 

Mark nods which only spreads the rush of heat in his head. "You're perfect, William. You're so perfect, baby, you're so good, feel so good." Babbles Mark as he fully bottoms out, hips flexing. 

William whimpers and squeezes Mark's shoulders again. "Wait a minute, don't move-" William can't even finish the statement cause Mark immediately stills his hips, balls nestled against William's ass.

Mark mumbles into William's neck and up to his ear carefully, kissing it. A shock of fear had burnt through Mark like a bolt of electricity, freezing him in the worry that he hurt William. "I won't, I won't, baby. Are you ok?" 

William moves one hand up to pet relief back into Mark, the other lightly grasping the back of his neck and rubbing it. "I'm better than ok, I feel so good. You feel perfect inside me. I just need to adjust, ok?" 

Mark pulls his head back and opens his mouth to question further but William catches it in a kiss. Before Mark can worry anymore William's assures him, his voice tight and thicker with emotion, "You make me feel.." He sucks in a shuddering breath. "You make me feel complete, like there was something missing inside me and I didn't know until you filled it." 

Mark chokes out a moan, his heart aching and hands squeezing William's back in a physical representation. "Me too, baby, like I've been waiting for something. But I didn't know and I- I don't-'' Mark doesn't know how to explain the way he's felt until now and he gives up trying with a little frustrated huff.  The dark eyebrows are even pinched in the cute pout.

William smiles in adoration  before kissing any frustration out of him. "I understand, Mark." William whispers, voice tender while he strokes Mark's cheek. Then William clenches as tight as he can. 

Mark moans, shuddering at the ripple of tight, wet muscle over his entire cock. It's a heavenly vice. "Aah-William?" 

William rocks his hips a little, biting his lip and looking up at Mark through long lashes. "I'm ready, Mark."

Mark gulps and nods before helping William's movement, dragging himself out so just the tip remained. Then the slow plunge back into the warm depths has Mark shaking, "I'm not sure how long I'll last."

William shakes his head with a smile, petting the back of Mark's neck in an affectionate manner. His chest heaves with a whine, cock twitching against his lower stomach. "Don't fight it, babe. Cum in me when you're ready, mm, spill it inside-"

Mark's cock throbs so hard it scares him for a second, thinking he was about to cum. So he kisses William to quite him for a moment. "Fuck, William, you're gonna make me cum just from talking."

William looks up at Mark, mischievous. "I'll test that la- ah! Mark!" until Mark thrusts and hits William's prostate deadon, making the pale man cry out in pleasure. 

The smirk Mark bears is a little self satisfied, proud he found William's spot again so quickly. "Heh, there it is." William's legs wind around Mark's hips, heels pressing into the thicker ass and drawing him as close as Mark can press into him.

"Again, please!" 

It's a redundant question but Mark wants to hear William say it, he wants to know that he's the one making William fall apart. Just like William is doing to Mark. "Am I making you feel good, baby?"

The answer hitches on a cry. "So good, I-I- '' The human is gasping through the pleasure and build of emotions inside him that threatens to snap, like a metal wire spun too tight. William throws an elbow over his eyes that begin to water, desperate to hide the embarrassment from Mark. Who, to his credit, has seen every action and knows what William's trying to do. He nuzzles against the arm covering William's eyes before gently pulling it away, getting to see the watery blues that tug his heart strings like the violin William still plays sometimes.

"Look at me, William. Baby, look at me?" Mark asks through a soft whisper that wavers as Mark's own eyes water. He kisses William, deep and passionate in an attempt to drive any fear out of his beloved. "It's okay, don't hide from me, baby. Let me in." Mark's soulful brown eyes don't dare budge an inch, keeping William's gaze locked. "Let it all out." Mark tries to further draw William out by giving a slow, lewd gyration of hips with the tip of his dick pressed right against William's prostate. 

The moan that falls from William's throat bursts into a teary cry. William can barely meet Mark's gaze through the shed of them but he does anyway, 

Wet drops slide down Mark's cheeks and onto William's chest, his abs clenching with the swoops of an unyielding wave of intimacy. "I love you. I'm in love with you." Mark can't help but grunt lightly with the move of his hips and the warm drag of William's walls pulling Mark apart at his very seams. 

William's sob catches with a moan and whole body shudders, he nods and wraps both arms around Mark's shoulders in a tight embrace again. "I'm in love w-with you too, I love you so much, aah, Mark, don't stop, don't- puh-please-

He's begging Mark to keep moving his hips and striking William's prostate, yes, but it's more than that, too. It's a silent plea that Mark recognizes, William doesn't say it but Mark hears it anyways. 

Don't leave. 

The air is hot around them, but Mark doesn't even notice that they've lifted off from the bed all together. He's holding William so tight to his chest he doesn't dip even slightly when they hover. And Mark is lost in the intense feeling of tight heat on his dick combined with the crash of adoration through his entire body- all Mark can think of is William . "I won't, I'm here, William. I'm right here, I'm never gonna leave you." 

William throws his head back, legs slipping a little on Mark's sweaty hips. "Ah, mm-Mark! I'm, I'm so close! I'm gonna- I'm gonna- " The petite man hiccups through tears and moans, his body easily taking each passionate thrust Mark gives him. 

A trembling hand winds between them to jerk William off, the other arm flexing as Mark holds the man tight to his chest and squeezes. "Me too, me too, cum with me, baby. I want you to cum with me, you're so beautiful."

Tears of love and overwhelm slide off William's jaw that hangs open with his cry, "Ahh! Yes! Mark, I- I'm-" Precum is dribbling between Mark's fingers, wetting William's throbbing shaft with the frantic way Mark pleasures his lover, nodding. 

"Shit, William, baby, cum for me. Cum..." The deep, rumbling groan from Mark's toned chest tapers into a sharp inhale when William's hole flexes, finally pulling Mark over the edge and tumbling him down the cliff of rapture. " Haah- I'm cumming!"

The blue eyes flutter, trying to keep contact with Mark but William is thrown into an entire other orbit when his body climaxes. "Mark!" Wails the man, a fresh spring of tears wetting the long eyelashes. Cum shoots across William's chest as his cock aches, flushed and throbbing with the most intense orgasm William's ever experienced. 

Mark buries his face into his lover's neck, desperate to curl as close to him as possible, wishing he could physically mold them together so they'd never part. "William! " His hand slides over the expanse of William's slippery back, keeping him close as Mark thrusts through every last orgasmic wave. The two are hovering in a wobbly way, Mark far too excited and focused on chasing this high with William to notice that he's flying in the first place, let alone keep them steady. 

But once the primal feeling of need starts to ebb into a glowing tingle, Mark notices that the bed is a good three or four feet below them. He chuckles through his little pants of effort and lets them lower back down slowly, so as to not freak William out whose eyes aren't even open. "Are you ok? Did I hurt you?" 

The blue finally peaks through, glossy and like William were looking through a haze. He smiles, slow and lazy while stretching his legs out. "No, babe. you didn't hurt me. That was.. Amazing. So amazing."

Mark lays on his back instead of planting himself across William's chest like he wanted, pushing an arm under his shoulders. "Thought I was the half virgin here?" 

"Shut up, you're ruining the afterglow." William still nuzzles into Mark's despite this, curling one arm on top of the broader chest. He leans up to place a little kiss on Mark's lips, who smiles. 

"I mean it, you know?"

William returned to nuzzling Mark's shoulder with the strong nose, humming softly. "Hm?"

Fingers trace nonsensical shapes over William's cooling skin, a warm, devoted look laid upon the fair man. "I love you."

William cracks open one eye, reaching one hand to cup Mark's cheek and thumb over his lips. "I love you too, and I think you know I mean it."

Mark nods while wrapping both arms around William's body and kissing his forehead. They move and slot together like puzzle pieces, made to fit in between each other's edges. 

"I do."
