"Shou, you’re supposed to treat yourself on your birthday!” Yamada whined as Aizawa again turned down his suggestion of a birthday celebration.

“Not interested.” The fatigued instructor replied, shutting the bedroom door in the blonde’s face.

He could still hear muffled words from Yamada trying to argue through the door as he returned to his desk to finish that night’s workload. It was an argument that repeated itself annually and, while sometimes the loudmouth won, Aizawa had zero interest in being dragged around this year.

As the night drew darker, it seemed Yamada was respecting his choice and did not return to continue his birthday debate. At least for now.

As he finished his work, Aizawa sighed, leaning back in his desk chair as he stretched. Glancing at his phone showed that midnight had passed some time ago, indicating it was now Aizawa’s official birthday. He already knew to expect further protests when morning came, but for now, he was able to enjoy the silence.

Treat myself? He laughed at the thought, arm resting over his eyes, there is nothing I have any inter- an image appeared in his mind, contradicting the incomplete statement. There was one thing Aizawa was very interested in. Swallowing at the passing imagery, he attempted to bury it by reaching for his phone to browse for something to distract the thought process that had begun.

Zipper undone and member in hand, he did his best to relieve himself as he watched some preferred videos, breath heavy as he pumped his fist but nothing met the particular itch his brain had this night. With a defeated sigh, he released his aching shaft and stared at his ceiling. What he wouldn’t give to have something real around his cock right now. Lips… soft hands… the warm, wetness of-

“Fuck.” He growled into the empty room, eyes shut tight as he fought the craving he felt. The urge building within.

Yamada’s words flashed into his mind once more as he fought his irritation, his breathing calming as he considered them.

“Treat myself…” he glanced at the balcony of his room and his face went dark with resolve as he fixed his pants and stood, “why the fuck not.”

He moved quickly, taking only a few minutes to reach his destination from the facility dorm. Not wanting to try and explain why he was out so late or why he was moving towards a third-year dorm.

Or how he knew that the lock of a particular balcony door for one room had yet to be fixed.

Or exactly why he knew that the student in that particular room used sleep aids...

It was best no one caught him to ask such things he thought as he stared at the lovely woman sleeping soundly in her bed, unaware of the teacher standing over her.

Aizawa was silent as he watched the object his recent obsession affection rest, taking in the shape of the form molded around her by the blanket. As if in reaction to his stares, she shifted and the cover fell away revealing the large t-shirt covering her upper body, her chest moving gently as she snoozed.

He could feel his growing arousal as he watched her pert breasts rise and fall. Leaning on the mattress with a knee, he discreetly tugged at the blanket and guided it until only her feet were hidden. To his delight, the tee had ridden up as she slept; revealing the delightful pattern on the panties that hid her treasure from him.

Resisting exploring the new sight, his gaze drifted to her shirt and began to guide its fabric up to reveal more. His breath struggled to remain steady as his fingertips trailed across her skin as he adjusted the shirt's position, watching as more of her flesh appeared.

He snapped away as she shifted in her sleep again, but he returned gingerly as she settled. Hand hovering as he finished his objective, he took in the sight of her bare chest moving in tandem with her breath, begging for his touch. Licking his lips, dry with anticipation, he carefully - almost delicately - brushed his fingers across the tender mounds.

As the tips of his fingers brushed across her nipples, the peaks began to harden in response. He sucked in a breath at the reaction, yanking his hand back to cover his mouth. Taking a deep breath through his nose, he considered how he should proceed.

While he wanted to take the time to explore every inch of the darling student whose existence had consumed his every thought… he didn’t have that luxury. With no idea how heavy her sleep was or how long her medication would last, she could be awoken by his actions at any moment. He had come this far, it would be a waste to get caught - to ruin everything - if he didn’t get to have some fun.

Now calm, Aizawa leaned closer to cup a breast, massaging the ample flesh while his finger danced the edge of her bare tips; enjoying the sensation of it hardening from his touch. Once he was sure that wasn’t enough to awaken her, he dared to do more. The bed creaked as he came to lay next to her, hand moving to cup the far breast while he blew a subtle breath of air against the aching tip of the nearer one, evoking a nearly muted moan from the woman.

Eager to hear more from his lover, he encapsulated the delicate point with his mouth and sucked gently. His tongue circled the nub while his hand caressed the other tip.

He was nearly ready to erupt right there, finally enjoying her almost enough to send him over the edge. Yet he fought the urge, releasing his mouth from her, looking up at her sleeping face. She had begun to blush at the stimulation he provided which brought a smirk to his lips.

Deciding to press his luck further he released the soft hill, gliding his fingers back down between her legs, slipping underneath the elastic band of the cotton undergarments. A question that had burned in the back of his mind was answered as he felt the curls that carpeted her warmth.

Head resting against her breasts, he relished the exploration of the downy mound until he felt wetness on his fingertips. A struggled groan from the sleeper came as a finger slipped into the slick folds, touching the sensitive nub that was nestled within them. He teased it; circling, rubbing, and pressing against the heat of it. Her breathing became more ragged as he continued. Beneath heavy eyelids her eyes moved, her lips parting to let out small but sweet moans.

Eyes still on her face, Aizawa captured her nipple in his mouth once again and added to her arousal, desperate to hear more.

Her legs twitched at his encouragement, unconsciously spreading for more. He was happy to abide by the request, his fingers moving from the twitching bud to her depths. He began with a single finger, easily slipping his middle digit into the damp entrance, feeling the pulsating walls of her insides cling to him eagerly.

As he pumped his hand rhythmically within her he concluded that he wasn’t leaving until he filled her properly. No matter the cost.

One finger became two as he began to work on her, spreading her with his fingers to ready her for what would come next. Her body quivered as he found certain spots reacted more than others and soon his pace increased. His lips detached from her breast to readjust for easier movement and to watch her face as he plunged into her, his thumb doing its best to rub the swollen bud above her entrance.

Finally, to Aizawa’s delight, her hip bucked against his hand as her insides tightened around the fingers, threatening to keep them. Her velvet walls shuddered at the release. His breath shook at the feel and sight of her ecstasy, his pants as tight as possible as his body responded to the show.

He withdrew from her slowly, watching for any sign that she was waking up. To his relief, and amazement, she did not stir, chest heaving from the orgasm. He would need to find out her prescription for himself.

It took all remaining self-control - as little of it as there was - to not rip the thin barrier from between her legs and thrust into her for his own relief but the best course of action was to give her body time to calm down, she would be far too sensitive right now and that could easily wake her. No, he would take a little more time to enjoy her body before he opened his real present.

A low whine came from the bed as he repositioned himself above her as if a cat were crouching over its prey. Fighting the urge to make her suck his fingers clean after toying with her, he instead used his clean hand to grip her chin and position her face to plant soft kisses on her lips, face, and neck. He wanted to enjoy the unspoiled taste of her before he moved on to his next goal.

Once satisfied, he repositioned again; balancing his weight carefully, he sat over her chest while making sure not to apply any pressure. Once sure of the position, he unzipped and reached into his trousers. Purposely using his sullied hand to coat himself in her, he withdrew the swollen member which twitched at the cold air of the room as it was exposed. Precum dripped happily down the shaft, no longer impeded by anything.

He stroked himself slowly, happy to have some relief from the agonizing pressure that his pants had caused him. He made sure to hold himself just right so he could feel her breath, which had begun to calm, as he stroked. Making sure not to press too hard, he guided the tip to kiss the sleeping girl’s lips.

A low groan escaped Aizawa as he felt her tenderness and he did nothing to stop the sound, almost wanting her to wake up so he could shove into her mouth to keep her from crying out at the sight of one of UA’s teachers hovering over her with his cock out. However, she didn’t stir as he traced her lips, coating them with his clear liquid.

Curious to see just how far he could go, he guided himself to the part in her lips and applied pressure. There was resistance but soon they parted and the head of his manhood slipped inside. He shuddered as the flesh surrounded the tip, although he could not go too far as he met with the barrier of her teeth he didn’t mind as he angled himself to slide into the pocket of her cheeks. His hips ever so slowly as he pumped into her jaw.

He wanted so badly to reach down and guide her mouth open so he could slip inside, feel her tongue encircle his shaft, the warmth of her throat. The mere thought mixed with the feel of her made him pull out, panting and holding back the urge to cum. As good as it may feel to use her mouth, he had to hold back from his release just a bit longer. He had a goal and if he came now, the clarity of what he had done would drive him to run before fulfilling it.

Needing time to calm down before he blew, Aizawa sat on the edge of the bed and considered his prey. Her face needed to be cleaned off of any remnants of his indulgence, her breast was a bit red but that would fade before morning, and obviously, her clothes would need to be put back once he was done. Nothing else caught his eye as a potential indication of his visit as he created the mental checklist.

Once he had settled down enough to continue his fun, he removed the blanket completely from her and positioned himself between her spread legs. With delicate movements, he took hold of her panties and began to slide them off. Carefully lifting one leg to remove its hold, he left the garment clinging to the other.

He swallowed at the sight of her legs spread before him, her womanhood exposed. He wanted to play more, to feel her quiver against his tongue and taste her as she came over and over. Yet he knew it was either that or what he really wanted, he wouldn’t be able to handle more with how worked up he was.

Any reservations Aizawa may have had about his current actions faded away as he withdrew the foil package from his pocket. He cursed as it crinkled loudly whilst being opened, even though he knew by now that it wouldn't wake her. Stuffing the wrapper in his pocket, he sheathed his engorged flesh in the rubber. As much as he would prefer to feel her properly, the evidence he would leave behind would be far too obvious.

His body quivered with anticipation as he adjusted himself to prod at the dampness between her legs. Sliding his length up and down her moist slit he counted himself in her dew, grazing the aroused bulb as he grinded. While lube was preferable, it hadn’t been something to consider in his unusually irrational mindset as he rushed from his room. Covering himself in her juices was the best alternative to avoid hurting her. The last thing he ever wanted was to hurt his beloved.

When he was sure he was suitably slick, he directed his head to her dark haven and began to ease himself into her; one hand holding his girth as he guided it while the other hand pressed into her thigh, holding it to assist with his access. A sigh of delight escaped him as her warmth surrounded him, her body tensing at the intrusion. Allowing a few moments of bliss at the penetration he began to slip slowly, inch by incredible inch, inside of her until he felt the end of her depth and could proceed no deeper without causing pain by pressing against her cervix.

“Fuck…” Aizawa moaned in elation as she encompassed his manhood, pulsing and shivering as it tried to accommodate the unknown object. After who knows how long of lusting after her, he was finally one with her, feeling how truly perfect for him she was.

Now he was inside, he lifted her legs and held them together with one arm, having them find purchase against his shoulder. The action caused her to squeeze tighter around his manhood and encouraged him to continue. Once her legs were secure, he moved; withdrawing himself as much as he could handle before his need propelled him to enter once more. His hips rocked at an agonizingly slow pace as he pumped in and out of her, he stared with adoration as her body swayed oh so tenderly in time with his movements.

Her breasts bounced gently with the rocking and the erotic scene of it only elevated his lust at the sight. He leaned forward against the angle of her legs, pushing them towards their owner, and put his weight on his free hand as it rested near her sleeping form and began to increase his tempo.

Heavy panting came from the teacher as he fucked the sleeping student, moans and whispers of unintelligible words of affection escaped his lips, his eyes fluttering as he began to lose himself in the feel of her. She trembled as small bouts of pleasure rolled through her as he used her body.

Her shallow breathing began to match his ragged tones as moans slipped from her mouth, darling whines, and soft squeaks of ecstasy as her body reacted to him. Her brow furrowed as her sleep-addled mind tried to process the feelings he was invoking; the bed began to creak as his motions increased and pressed deeper into her, kissing her deepest parts with his cock.

Any fear he held of rousing her no longer mattered to him, he wanted to see her face flush from the bliss he was filling her with. To see her eyes wide and glazed as he plunged into her with abandon. As her face contorted in her sleep, unable to comprehend how her body felt, he wanted to comfort her.

“It’s okay,” he purred in a quiet voice, “it's me, you’re safe.” He moaned, her name tumbling out alongside the reassurances from him as he thrust into her. Her feet waved above them in his arms as he started to lose his control, falling into the feeling of her heat enveloping him to wring every drop of his love.

Finally, after all the withholding, Aizawa allowed himself release. His body shuddered violently at the feeling that had been denied for so long. A sharp gasp ripped itself from his lips as he climaxed. His head hung as he shook, a black curtain of hair swayed as he let the electricity of it move through him. Beads of sweat rolled down his face, a few drops fell on the exposed chest of the woman he arched over.

As the feeling subsided, he stared at his slumbering lover and then sighed as he finally leaned back, relieving the pressure of his weight against her quivering legs as he moved and shifted them to lay beside him while he was still inside her tender flesh.

Combing his fingers through his tangle of hair he brushed the mess back over his head and took in the sight of the woman he had just violated. Her chest heaving, face flush with feelings she couldn’t understand, wet from his sweat and her womanhood drenched with arousal. A momentary glance at the ceiling and a deep sigh of personal resentment, he cautiously pulled from her, careful to keep the overflowing rubber attached as he did so. Once clear of her, he stepped off the bed quickly and entered the bathroom attached to the dorm room.

Once removed from his tired member, he tied and pocketed the used condom before grabbing a washcloth and returning to the bed.

As delicately as he could, Aizawa wiped down the victim of his abuse and returned her clothes and cover to their original locations. After a final glance around the room to ensure no evidence of his presence remained, he exited quietly while making a mental note to push the maintenance request to repair the lock to high priority.

The next morning Aizawa was doing his best to ignore his friend’s expected berating for refusing to celebrate as they walked to the main building for the day. It was an easy enough task to ignore the leather-clad hero’s ranting due to the overwhelming pounding of his heart filling his head. Anxiety and fear filled him, alongside acceptance, of what he was sure to come as they approached the building.

As they walked, Aizawa’s eyes instantly caught the form of his desire approaching encircled by her typical group of friends. Her group showed no reaction to the sight of them besides the standard greeting towards their teachers.

“Good morning, Aizawa-sensei. Present Mic-sensei.” She spoke, giving the warm smile that made his heart skip whenever he saw it. She gave no sign that her view of him had changed.

The pair replied in kind to the greeting and continued their stroll, Yamada returning to his argument happily.

“I’m just saying-”

“Fine.” Aizawa agreed, cutting Yamada’s tangent off.

“H-huh? Really ?” He asked excitedly, having never once gotten his friend actually to agree before.

“Yeah, whatever…” Aizawa glanced back at the group of students as they drifted away, “I suppose you’re not completely wrong. Treating myself on my birthday isn’t the worst idea.”
