itâs late, and the cool summer air engulfs you and erik at nearly midnight. the two of you are on the porch, leaned back against the railing. erik stands, though instead of his usual dark button ups and slacks, heâs more casual tonight. a blue t-shirt, jeans, battered sneakers. even his hair is a little longer, the waves coming loose, the stubble on his jaw grown out as well.
you sit on the floor of the porch, knees pulled up toward your chest. your head rests against erikâs jean clad leg, looking up at him with a smile. he returns it, one full of a warmth that he didnât often share. smoke curls in the air as he exhales, cigarette grasped lightly between his pointer and middle finger.
for the past ten months since charles and erik recruited you, the latter has held a particular soft spot for you. he helped train your abilities, discover new skills. he helped you find your pride in being a mutant. even in class, you two got along much better than the others. neither of you thought much of it, you were just good friends â it just so happened that you were a student. but you two were close, and he was different with you. you felt comfortable telling him things charles shouldnât know, like the parties you and alex hosted, or the fact that sometimes you hated your mutation. he was always there.
the same way he was now, a steady pillar for you to lean on, literally and figuratively. you chatted casually, something about hank and raven finally getting together. the moment was shared easily, no tension or even real worries. neither of you paid mind to the fact that youâd been outside for more than three hours, being as curfew happened to be three hours ago.
âcan i try?â you questioned, nodding your head toward the cigarette in his hand, cheek rubbing against denim as you did so.
he looked down at your outstretched hand, playfully rolling his eyes with a soft smile. âyouâll hate it,â erik chided, but handing the cigarette to you nonetheless.
inhaling shallowly, you felt the smoke fill your lungs, and you broke away, coughing. âyouâre right,â you replied with a strained voice. your hand reached back up to return the cigarette. still, your head felt a little fuzzy afterwards.
âi usually am. besides, you did it wrong.â it was common for the man to playfully lecture you, bringing a smile to both of your faces.
âitâs kinda cold out here,â you commented. this made erik sigh, shaking his head in breathy laughter. you were wearing pajama boxers that covered virtually nothing, paired with one of your many little tank tops â obviously you were cold. you didnât even have shoes on.
âwould you like to go inside?â
âand go where? i donât wanna go to bed yet.â
erik shrugged, dropping the butt of his cigarette and stomping on it with his sneaker. âdid you want to go to my room?â
the question was innocent, not holding the perverted undertones one may expect to hear when a teacher invites their student into their bedroom. right now, you werenât his student, and he wasnât your professor.
after considering the suggestion, you nodded, adjusting your shorts. he reaches his large hand out to you, and you take it, engulfed in his warmth. erik hauls you to your feet with casual strength, the kind that makes you smile a little.
he walks beside you, a hand resting softly on your lower back as he opens the glass door, letting it shut behind him. he gently leads you down the corridors, pressing his pointer finger against his lips in a reminder to be quiet, though that did not mean much when he grinned playfully.
his door opened to reveal a room similar to yours, though larger. the walls were a soft beige, joined in all the corners and edges by dark trim and accents. his king bed sat against the middle of the far wall, under his window. the room smelled of something warm, distinctly erik. it brought a smile to your face. one that had something behind it that even you couldnât decipher.
the large bed, neatly made save for a hoodie thrown on top of the maroon comforter, called to you.
âthis is so nice,â you called out, throwing yourself onto the foot of the bed with very little grace, one leg hanging off. erik chuckles at your immediate path to his bed, shaking his head a little.
something you notice is the sheer amount of metal in the spacious room. it made sense â magneto, and all â but it felt odd, seeing it in his personal space, too. metal figurines and coins, little iron marbles on his desk, just trinkets.
âone of many luxuries.â his hand ran across his sharp, stubbled jaw, eyes falling shut for a moment. when he opened his eyes again, erik caught sight of you in a different light, literally and figuratively. youâd turned on the lamp next to his bed and had sprawled out once more, moving his pillows to your comfort. it seemed as though this was more your space than his. the image of that brought a smile to erikâs face, something reserved only for you â though you donât see it, being as youâre tinkering with a bottle of cologne on his bedside table.
you had no reason to smell his cologne from the bottle, seeing as it surrounded you now in his sheets, but you knew it would be different. the glass did not hold the same warmth his body did, and neither did the fragrance, no matter how pleasant it was. you enjoyed it far more when he wore it.
âsmells like old man,â you joked, crinkling your nose in face disgust. that did nothing to hide the smile that felt sweeter than honey coming to your lips.
you lay on your stomach now, one pillow under your arms and chest as you faced the bedside table to be nosy. this meant you didnât see erik approaching the bed and laying down across the bed widthwise, until you felt the dip of weight.
âdo i now? maybe you should respect your elders, insolent girl,â he chuckled out. erik didnât need to look at you to see you rolling your eyes. the man reached over his own torso with the hand that wasnât behind his head to flick the exposed strip of skin between your tank top and shorts.
âyouâre too mean to respect.â a little huff of air came from you, though all in good fun. you twisted a little to move away from his hand, though the tiniest bit of contact felt like electricity surging through your ribcage.
despite this, youâd continued on with your nosy findings, and had found the book he was reading, one you likely would have deemed boring before later reading it yourself. you flicked through a few pages before setting it back down.
at some point, youâd forgone your nosiness and instead set your eyes upon erik. his perfectly angular nose, his blissfully shut eyes, the way his muscles made themselves prominent through his t-shirt.
one arm is looped behind his head, bicep nearly bulging from the simple stretch, and the other rests on his abdomen, clutching a pack of cigarettes. his dark blue shirt rides up enough above his jeans to where you can see most of his stomach, from above his navel to where the waistband of his dark boxers makes itself visible, enough to see the dark hair starting at his navel and descending lower.
the silence in the room was pleasantly calm, though only if for a few minutes. youâre sure erik had no idea you were looking at him, being as his eyes were closed â but he knows. youâd never stay quiet for this long otherwise.
âyâknow, professor, iâd say youâre much better looking than charles,â you cut though the silence. you knew he would tell you to call him erik, and you generally did, but sometimes the title grabbed his attention more. thatâs what you believed, anyway. you always had his attention.
âerik,â he reminded, a lazy smile on his lips. âi think you might be biased, darling. you look at me more often than you do charles.â erikâs eyes remained closed, but his brows furrowed a little now. he certainly hoped you looked at him more than charles.
you just huffed out a laugh, mostly distracted by his face.
âyou stare an awful lot,â erik remarks, eyebrows raising in emphasis. his long fingers tap mindlessly on the pack in his hand, as though debating another smoke. he doesnât need it, though. he has you here and deems that more than enough nerve stimulation.
your eyes widen suddenly, your face feeling a little warmer at his words. âyour eyes are shut,â you murmur, confused as to how he knew you were staring at him.
something akin to laugh escapes his mouth, eyes finally opening. âbut you didnât deny it.â the way his grey eyes met yours mirrored the weight of your own previous gaze, a look that held something that seemed an awful lot like love.
you scooted a little closer to him, though not giving him a reply. the hand that idled on his muscular abdomen lifted, abandoning the pack of cigarettes on his exposed stomach. instead, his arm rose and wrapped around you, guiding your head to his chest. you were on your side now, a hand on his torso and your head resting on his chest and shoulder.
his body was impossibly warm and large beneath you, muscular frame radiating heat as though he had sensed the chill that hadnât fully left. even one of your exposed legs, hiked over both of his, had found warmth through the denim. neither of you dared to move, or even speak. not when your fingernails lightly scratched patterns along his chest and bicep, and your eyes started to fall shut despite you being quite awake.
âerik?â you asked, voice quiet and eyes still closed.
âmm?â erik hummed, looking down at your calm form.
âdo you think that if things were⌠different, you would like me?â
the older man frowned, but knew entirely what you meant. obviously, there was something between the two of you, but neither one had pursued. instead, a friendship that could nearly be deemed something else had been. and he knew people talked, but the only thing they could speculate was something secret. your friendship had always crossed the line of strictly professional, but he had never become anything more than someone you could trust.
thatâs what the rest of the school knew, anyway. they didnât know that on more than one occasion had you sat far too closely to each other, often overlapping, or that he stood outside with you for hours after curfew instead of telling you to go to bed. they didnât know how you looked at each other. erik knew, though. he saw it in your eyes when you thought he wasnât looking, because it was the exact same look he had in his.
âi do like you.â his breathing stayed steady, his heartbeat a constant in your ear.
you frowned a little. âi meant.. yâknow, just forget it.â
erik rubbed your back softly, communicating understanding. âi know what you meant.â
a smile finally graced your lips, one softer than just minutes ago. âyouâ really?â you tried to confirm, itching to know if he felt the way he claimed.
his arm just squeezed around you a little tighter, a feeling that you found nice enough to slowly doze off on his chest. erik stayed awake though, absorbing the weight on his body and his mind. he knew it was wrong; you were a student who trusted him to teach you control over your abilities, to train you and be a stable figure in your life.
but how could he stop the lingering looks, the late night conversations that ended up like this? you were the sunshine in erikâs life, no matter how much he says otherwise.
so he doesnât move, and he lingers in the sensation that heâs grown accustomed to. erik doesnât fear the consequences that would fall upon him if someone found out, but he fears what would happen to you. over the past few months, heâs learned that you seem to need him just as much as he needs you. it shows in how you come to him in tears, or how you never seem to let him get far from your touch.
thereâs one question heâs been asking himself, though, and been mindful of not thinking about it when charles is around. is it love? could it be love if you canât be open about it? erik lehnsherr had to relearn how to love after his life was shattered into pieces, and he knew he loved you. he happened to have a pretty good feeling that it wasnât totally one sided, but he didnât mention it.
it certainly felt like you loved him when you sat on the porch in your pajamas, head resting on the side of his leg, looking up at him with soft eyes. it felt like love when you laid on his chest and felt safe enough to fall asleep.
eventually, his eyes set upon you, erik fell asleep himself. if he was being honest, it was the best sleep heâd gotten in a long time. he held you close, sideways on the bed and blissfully knocked out.
by the time he woke up, it was five-thirty am, too early for most of the mansion to be up. pale blue light filtered in through erikâs window, casting light shadows on you. you were still asleep, face mostly hidden in the side of his chest. you were so peaceful, lost in the confines of dreams.
regret inched into erikâs mind, but it washed away the second he saw your hand fisting his t-shirt when he tried to carefully move you off of him. your eyebrows pinched a little when he slowly lifted your sleeping body, setting your head on a pillow and off of him.
âyouâre okay, honey. iâll be right back,â he whispers, brushing his thumb along your cheekbone. his voice is soft, but holds a gravelly tone that shows he just woke up.
your eyes stay shut, but you grumble a little from being moved and the loss of his body heat. but as he strokes your cheek, his eyes soft, the furrow in your brows dissipates back into that peaceful state.
when erik stood, he moved away from the bed, but could not tear his eyes away from you for the first few minutes. when he did, you still remained the only thought in his mind.
he went to his bathroom, the warm light flicked on showing him the messy waves on his head and his overgrown stubble. he should have shaved yesterday, but you had said last week that he looks better with longer hair. it feels more natural, not like heâs hiding in the confines of professional appearance.
when he gets out of the shower, waves damp and messy across his forehead, erik is still mindful to be quiet when making his way back into his bedroom. however, when you come into sight, youâre mostly awake, sitting up against his headboard in a ball. he feels a little flustered when he realizes youâve woken up, considering heâs still damp and has only a towel slung loosely around his hips.
your facial expression mirrors his, albeit with more sleep lingering in your eyes. erik stands still for a moment, lips parted and cheeks a little warm. his hair is slicked back in loose waves with the remaining water, and you can see his muscular chest rising and falling as his breathing picks up.
âiâm sorry, dear, i.. didnât know you were awake,â he finishes with a brief smile. as he grabs a few items of clothing out of his dresser, youâre still in the peripherals of erikâs vision, turned away as though to offer him that brief modesty.
âitâs okay, erik,â you reply softly. it seems the light embarrassment of seeing him â or perhaps it was that you were staring â had found you, your cheek caught in your teeth.
erik turned back to you, abs on display in a manner charles would call âa little sluttyâ. âiâll just be getting dressed, iâll be out in a moment.â with that, he disappeared back into the large bathroom, the door clicking softly behind him.
as soon as he was gone, you silently screamed at yourself, unsure of even what to do after seeing probably the hottest man to ever exist with nothing but a towel on. you hoped that being several rooms away, and not technically being allowed to be in the teachers suite, meant charles would not be able to discover these thoughts.
it may have taken a moment, but you regained your composure, stretching your back and standing. you didnât want to leave quite yet, and truth be told, you were afraid you would get caught.
just as soon as heâd left, erik returned, clad in a grey long sleeve t-shirt and jeans, a casual sight you enjoyed so much. the sleeves had been rolled up to his elbows and left his muscular forearms exposed. when he met your eyes, he offered a smile with raised brows. the barely-there light of the sun inching into the sky cast long, blue shadows along his face that made him seem all the more serene.
âso.. erik, how am i supposed to leave without someone seeing me?â you asked, voice a little low out of caution. your fingers twisted along the hem of your shorts, hoping erik would have an answer â he usually did, though.
his eyebrows pinched a little, sight now falling upon his door. with it being so early, he assumed the only real threat could be logan, considering he enjoyed running off to do god knows what at awful hours. long strides, relaxed in manner but tense in emotion, took him to his door, looking out the peephole. nobody, not in the teachers suite, anyway.
âi suppose iâll just.. walk out. then youâll follow. if anybody asks where you were, youâll say you were outside. if they see us* together, you had a question about an assignment,â the older man instructed carefully, hoping you could remember it. those instructions made your eyebrows furrow, looking at yourself â wearing a tank top that did virtually nothing, boxer shorts that were only for modesty purposes, and white socks. nobody would believe you were outside. but even still, you couldnât think of anything else, so you accepted.
when he opened the door, erik looked out for a few seconds before looking back at you, giving a shrug and a nod.
no noise came from anywhere in the mansion, save for the soft padding of your socked feet and the quiet tap of erikâs boots. it was nearly empty, everybody asleep at nearly six am on a saturday. when you made it to your room, erik close behind, you opened the door with a bashful smile. he had to reason to follow, except that he wanted to spend a few more minutes with you.
erik leaned against your doorway, telling you to get some real sleep, things like that. his soft grey eyes met yours with unwavering affection, telling you all he didnât say. the stubble on his jaw only accentuated his smile, a kind of adoration nobody else saw.
the large windows in the halls let you see him in the early morning light, the day young and already so full of life. unable to rest your eyes off of him, a loving caretaker in his whole being, your hand inched toward his again.
something came over you, though. maybe it was the heat he radiated, or maybe it was the fact that nobody loved you so deeply, so surely, without ever saying it. but without warning, your hands found either side of his stubbled jaw, pulling him in for a slow kiss. it wasnât rushed, not even desperate. it was the work of almost a year of friendship shattering into what it really was.
erikâs hands found their places respectively on your waist and the back of your head. his soft lips moved in sync with yours, pushing you back as he yearned for more. the door stayed open despite him walking you backwards into your room, your body pinned against a wall.
neither of you wanted to pull away because you knew what would eventually come â guilt. but when you did, his lips were parted and his chest rose heavily, your lips swollen and panting. a smile came onto your lips though, out of breath.
erikâs hand on your head slipped to cradle your face, his grin mirroring yours when you pulled away.
âso.. iâll see you later?â
he chuckled, placing one last gentle kiss on your lips. âiâll see you in a bit,â erik replied as he walked out the open bedroom door, closing it behind him.
