A/N: Please note that, although there is a sexual aspect of Adult Nursing Relationship (ANR)/ Adult Breastfeeding Relationship (ABR) is not strictly sexual. It can be seen as foreplay or kink; but mostly it is about being a source of emotional comfort and support. I hope I managed to put this point across in this fic… Other than that, please enjoy!

Summary: At Izuku's breast he felt completely at peace. The sound of his heartbeat and the steady flow of milk gently lulled him to a state of tranquillity. He felt loved and cared. No longer worrying about being All Might. Right now, he was just Yagi Toshinori.

Symbiotic

"Your vitals have improved." Recovery Girl commented as she went through the results of his monthly check up test.

Toshinori smiled soon as he heard the verdict. It was true, he too had seen the changes in his body. The extreme gauntness was now slowly beginning to fade as his weight steadily climbed. The red flags littered across his blood work had reduced with every subsequent test. He wasn't in a constant state of lethargy and pain. He could even hold on to his hero form a little longer than before – the short bursts he usually did for comedic effect weren't taxing on his body, but it wasn't something he had tested yet.

"You are finally listening to me." She chuckled amusedly, closing the file and logging the details into the system.

"Yeah…" He sheepishly answered, glancing down at his phone to read the new text message. It was from Izuku, informing him that he was waiting by the school gate. He frowned slightly, because the teen would usually meet with him at his apartment.

"That should be all. Just keep sticking to it, and you should be in the safe zone in no time." The school nurse smiled as she dismissed him from the UA infirmary.

"Sure, will do." He returned the smile, thanking her as he redressed and exited the room.

Walking towards the entrance, Toshinori spotted the teen waiting by the gate. Leaning against a pillar and typing furiously on his phone, the blond allowed a fond smile settle on his face at that familiar sight. School had finished some time ago and noticing the lack of change in attire indicated Izuku had waited for him since the last bell.

"You didn't have to wait for me here my boy." Toshinori commented as he offered to take Izuku's bag. He could see the weight was beginning to bother the teen, as he was constantly adjusting the straps away from his chest.

"I could have waited at your apartment." Green eyes crinkled as Toshinori was partially blinded by the smile, "But it would have been boring to walk alone, Toshi."

"Izuku…" He whispered exasperatedly. They had agreed to use their given names after school – it was unusual for Japanese culture, but given how intimate their relationship had become; it only felt right to address each other likewise in private.

Before he could reprimand the teen for waiting hours outside for him, Izuku cut him off, "It is one of the heavier days." as he lightly parted his blazer, and Toshinori could see the front of the teen's white shirt was nearly soaked through. Due to his close proximity, he could even pick out the familiar scent of sweet milk as well; any longer Izuku's entire shirt would have been drenched.

"I'll call a cab." He immediately replied as he hailed one via the app on his phone. The last thing he wanted was to take public transport with Izuku in such a state. It was close to rush hour and the line they were taking would be soon packed with people. The school blazer still hadn't shown any dampness, but he wasn't risking it with so many people around.

Quickly removing his overcoat and placing it on Izuku's shoulders, they both climbed into the taxi. Instructing the driver of the location, they both continued to spend the entire ride in silence. Toshinori could see the teen would occasionally touch his chest, but withdraw with a slight flinch of pain. They would usually meet up a little earlier; but due to his check-up, their meeting time had been pushed further back. Unfortunately, this event coincided with one of the days Izuku's milk production went overboard.

Forcing his eyes to the view outside (no matter how much he wanted to watch Izuku instead, but doing that would only alert the driver), Toshinori thoughts drifted back to his check-up. Those positive results were due to the recent developments of Izuku's and his relationship. It started all those years ago when they first began training on the beach. The young teen had mentioned his chest becoming tender and swollen, but he dismissed those symptoms as Izuku putting on muscle due to the strenuous work out. However, looking back it was obvious considering the darkening and enlarging of his areolas.

The teen hadn't started lactating till after receiving his quirk. Toshinori often contemplated if this was the boy's birth quirk, but he'd seen the medical paperwork when Izuku was filling out the application for UA and it confirmed the boy was quirkless. Either way he knew his improving health was due to the regular consumption of the teen's breast milk. He had read on the internet that it was higher in calories, which was most probably the reason behind his increased weight. Though when he first drank from the teen, he knew nothing about it; as it was the result of panicked thinking due to Izuku collapsing at the beach in pain during one of their after-school evening meetups.

"My boy!" Toshinori cried out as he saw Izuku double down in pain, falling to his knees. "What's wrong?"

Clutching his chest as the teen looked up. The blonde could see his student's face was tensed and flushed with pain, as wrapped their arms around themselves. He had tried to reach out, but Izuku only flinched away from his touch. His student was extremely tactile with him (not that he minded, being severely touch starved he had welcomed the constant physical contact), and seeing the teen shy away had hurt.

"Please tell me what's wrong." Toshinori pleaded. "I'm your mentor and friend, you can tell me anything."

Izuku met his gaze, and he could see the teen internally fight regarding the decision to speak to him. After a few moments of silence, he heard a small voice whisper out hesitantly, "It's a bad day and I didn't have a chance to pump today."

Clearly not understanding the context, Toshinori carefully knelt down in front of his student as he softly asked, "Pump?"

He watched intently as Izuku parted his arms from his chest, allowing him to see the twin wet spots over where his nipples would be. Toshinori held his breath as realisation dawned on him. Entirely taken up with the sight before him, he almost missed the teen's explanation, "It started after the entrance exam and I even bought a pump to express the milk… Today was exceptionally bad… I thought I could hold out until after this meeting…But..."

Izuku trailed off, clearly embarrassed and humiliated by the sudden turn of events. He couldn't ponder on how his successor manifested this ability or if it was an unusual side effect of the quirk, for Toshinori could see the pain swirling in those green eyes – a pain he wanted to sooth away. Over the past year their relationship had grown awfully close, especially after the incident at Kamino Ward. With everything the teen had done for him and his promise to Inko about looking after the boy; Toshinori felt tremendously guilty of being the cause of this rather uncomfortable situation. He should have noticed it sooner. He should have helped.

"What can I do to make it better?" He asked firmly. Although he knew the answer was to express the milk to reduce the pressure, neither of them had a breast pump right now and the public knew of his civilian identity; so, he couldn't really pop into a shop to buy one either without sparking a media storm.

"I can massage some out, but…" Izuku suggested, voice tense as he pressed his engorged pecs.

"But it won't be enough." Toshinori finished and the teen nodded to confirm. They could risk returning to Izuku's apartment. However, gauging from tears gathered in the corner of those green eyes; waiting a moment longer or any sudden movement would only add to the already excruciating pain. Toshinori swallowed when another solution occurred to him. It would resolve the issue, but suggesting it would quickly make their situation increasingly uncomfortable. However, hearing the shuddering whine from his student as they unsuccessfully tried to express via their hands gave him the courage to overcome his hesitation.

"Izuku." He began slowly. Seeing the teen turn his focus towards Toshinori. "I can…" he drifted off, unable to find the right word, but gestured at the younger man's leaking chest.

Perhaps it was pain of the situation or rather the shared secrets between them, which made Izuku trust him and nod his head. Subsequently, Toshinori soon found himself laying his head on the teen's lap and arms in a secluded part of the beach. Izuku had removed his t-shirt and draped it on a rock to air dry as he leaned against the stone wall; adjusting Toshinori along with him until they found a comfortable position.

The entire situation was awkward and strange, but once the teen nodded his head as a signal to start, Toshinori took the nearest teat into his mouth and sucked; and what followed was the feeling of all those emotions melting away.

Toshinori smiled fondly as he recalled the memory. The taste of human breast milk had been strange at first – it was thicker and sweeter compared to the usual cow's milk, but warmer and held a rather unique flavour which he couldn't quite place. Something he could only associate with Izuku. Their first session was far from smooth as they both constantly shifted around to find the right angle or a more comfortable position (then again, the beach wasn't the ideal location for this sort of thing to begin with either). However, they wound up not parting until Toshinori drained both breasts completely dry. He had initially discussed with Izuku to only drink enough to make the situation more manageable and take the edge off the pressure; but it seemed some form of lull had come over both of them, and Toshinori wasn't going to lie; he had found the experience entirely enjoyable and addictive.

And he wasn't alone. Soon after, Izuku hesitantly began approaching him regarding his problem – playing it off as the breast pump would either take too long to empty him or it would never completely drain him.

He had been partially grateful the teen brought up the suggestion; for after that initial feeding, Toshinori had found his attention would always gravitate towards Izuku at any moment (specifically the teen's chest – cataloguing every light touch and feel his student made). The taste never left him, and that made him crave for the milk more and more as the days went by. He had even gone so far to anonymously procure some breast milk from donors, but they never held the texture or taste that Izuku's milk had. They all felt wrong.

It wasn't until after the second feeding in the privacy of his apartment, that Toshinori admitted he was fully addicted to the taste of Izuku's milk. Now thinking back, it wasn't solely the taste of the milk that drew him. It was the feeling that overcame him while he drank. The feeling of uninhibited safety, protection, trust and adoration. Those were things he never had the luxury of experiencing, and feeling them for the first time with such intensity was intoxicating.

He had been cautious about the after effects of drinking the milk as well, for his lack of a proper digestive system made his diet rather complicated. He initially worried about the sweetness, for his meal options after the gastrectomy forbade sugar. However, with every subsequent nursing session, Toshinori found no negative side effects. If at all, the milk made him feel better. He felt fuller but comfortable, digestion of his other meals became easier. His energy levels had improved and the chronic pain he'd known since the attack began to fade into the background.

He had wanted to test Izuku's milk, even brought up his observations with the teen, however neither one of them wanted to send a sample to the lab due to the unwanted questions that it could incur. Not to mention they both felt rather possessive about this particular private activity they participated in. Sharing this knowledge with anyone else felt uncomfortable and invasive – as if a stranger was encroaching into their special time and space. Hence, they shelfed that idea for a later date.

The taxi pulled in for a slow halt in front of his apartment. Toshinori had the foresight of purchasing a flat in an area known for people minding their own business. Yes, after his retirement there were the occasional greetings and stares, but largely people kept their distance away from him. The building was in a gated community and his neighbours were also recognisable people from various industries – so they understood the meaning of privacy and discretion.

Paying the fare and helping Izuku exit the taxi, they both made their way past the concierge and to the elevator. Whilst waiting to reach their floor, Toshinori observed Izuku text his mother that he would be spending the night over at his place and not to wait up. It was routine they had figured out through various trials and errors. Trying to move after a feeding session took a considerable amount of will power, as they both wanted to cuddle each other as they came down from the headspace it placed them in. With the current state of Izuku's outfit and the laundry services closing for the day, it would make sense for to wash and dry his school clothes overnight and send him home tomorrow.

Entering the apartment, Izuku immediately began undressing (being in a milk drench shirt for most of the day couldn't be comfortable). The teen felt completely comfortable walking into Toshinori's bedroom and pulling out one of his old button-down shirts to change into. Watching his protégé gather his clothes as he walked to the laundry room to wash his uniform, Toshinori smiled at how at ease Izuku was being in his home (It was almost as if the teen lived here – to be fair Izuku did spend a considerable amount of time at Toshinori's place). It had been about two years after all, since the time on the beach – they had plenty of time to ease into each other's space.

Toshinori undressed as well into a beaten-up t-shirt and sweatpants, while Izuku had now made his way to the kitchen. Hearing the fridge open and some clattering by the sink, he could assume the teen had pulled out some meat to thaw for dinner. They had already fallen into the act of an old married couple – Izuku being his beautiful young wife (trophy wife his mind cheekily added but he quickly tossed that thought out). Over time with the increased frequency of their nursing session, the teen had learnt of Toshinori's rather pathetic skill of cooking and feeding himself (not that he was bad, he just wasn't consistent); which led to Izuku cooking dinner and prepping a few additional meals for him till their next session. All Toshinori could say was, after tasting Inko's cooking, Izuku had inherited all of his mother's ability.

Seeing the teen dry his hands, Toshinori approached Izuku from behind and embraced him, "Shall we?... Before you drench this shirt as well."

The teen leaned back and looked up as he smiled at Toshinori, "It's not like you don't have other clothes… So, where should we do this?"

Toshinori contemplated the various locations where they could make themselves comfortable, "Let stick to the bedroom."

Izuku nodded as he filled a glass with water, following Toshinori to the bedroom (even though there was jug of water on the bedside table – a recent addition after his student had mentioned how parched he became during the feeding).

Settling themselves; Izuku seated and leaning against a wall of pillows, whilst Toshinori draped himself over the smaller male. Removing all of their clothing before climbing to bed (about a year ago they discovered the increased skin on skin contact only added to the whole experience). Once they had made themselves comfortable, Toshinori lifted his head from Izuku's lap and pressed a soft kiss on the teen's lips. There wasn't anything sexual in the kiss – not yet anyway. Their relationship only became sexual after Izuku's eighteenth birthday. Despite the nudity and close sensual nature of their interactions, neither Izuku nor Toshinori attempted to cross that line (perhaps it was a silent agreement between them to wait until Izuku was of age, and they were perfectly content with what was currently available till then).

From an outside perspective, it would have looked as if they had crossed the line a while back; but it wasn't for either of them. They had discussed the situation and how they felt about it in great detail, how they both felt soothed and at peace during the act of nursing. How their scents calmed each other down from a tough day. The warmth of embrace and softness of their touch reassured each other of their presences. How eyes and expression were full of love and adoration. For them, the nursing sessions were not about sexual tension or convenience – it was a reminder about how much Izuku and he cared for one another.

Yes, there were times; where Izuku would approach Toshinori to drain him (especially before a practical lesson) or if Toshinori felt rather weak or exhausted and needed some food fast he would approach his student. However, the tenderness of the moment would always overcome the initial need. They would even have brief nursing sessions at school, to take the edge of a particular distressing or troublesome situation. Not that they did it often, they had agreed school was off limits; but there were always exceptions made on days either Izuku or himself needed to feel grounded and comfort.

Izuku opened his mouth, allowing him in to deepen the kiss as they both relaxed into the feeling of merely having the other close by. Toshinori stroked his tongue against Izuku's languidly, it was a slow day today. Like most days, he wanted to savour and fully appreciate this moment with his partner. There were times they would rush through the motions – aggression and intensity colouring every move and action. Those days were great, but today Toshinori wanted to rejoice having someone he could bear himself completely open without a hint of worry. Noticing Izuku meeting his pace implied the teen had the same idea.

Tracing the younger male's teeth, enjoying his unique taste and suckling slightly at the bottom lip; Toshinori pulled away to admire his handiwork. Though most of the tension had left Izuku's face, he could still see a slight clench of his jaw (most probably due to the teen aching breasts). Glancing down Toshinori licked his lips in anticipation. Both pecs were swollen red, skin pulled taut and nipples erect with a tiny bead of milk forming at their tips. This wasn't as bad as the first time he had seen it, but if they had waited longer; Izuku's breast would have been swollen to the level he had first seen at the beach.

He wanted to lavish the teen with more affection before nursing, but seeing the pressing nature of the situation, Toshinori decided against it. Peppering light kisses around Izuku's face and neck, making a slow descent downwards to the troubled chest area. The teen had giggled and flushed lightly at the attention, but sighed when he pressed a few soft kisses to his engorged breast. Neither of them had to speak, for it was now instinctual to relax into their positions. Focusing on the teat closest to him, Toshinori gently wet the nipple with his tongue. Since he'd been doing this for nearly two years, he could already pick out the scent of Izuku's milk.

Tenderly taking the erected nub into his mouth and being mindful of his teeth, Toshinori supported the bottom of nipple with his tongue as he began to suckle. Izuku let out a deep sigh of relief as the milk began to flow into Toshinori's awaiting mouth. The milk was thin at first, but the more he pulled from the teen the viscosity of the liquid increased. It was warm and the texture became richer as he continued to drink, coating every taste bud on his tongue well. Feeling Izuku run a hand through his blonde hair, the slow stroking matching the unhurried pace of his nursing; soothed him immensely. Regardless of the pressure of his neglected breast, Toshinori recalled Izuku mentioning he preferred if the feeding session were drawn out as much as possible.

Toshinori could understand this, for he too felt the same. There was something about the whole activity which made him feel wanted, loved and cared for. Being at Izuku's breast and hearing that steady heartbeat combined with the feeling of a hand gliding through his hair; melted away all his anxieties and insecurities. Perhaps the lack of positive touch in his life made him crave for it – that as Yagi Toshinori no one wanted to approach him, let alone care for him. Yet here he was, in a position of being so closely bonded with someone, not even his All Might persona could have achieved.

He initially felt extremely guilty of doing nothing but taking from Izuku, but the teen was quick to dispel such thoughts by explaining what he felt during their nursing sessions.

"It feels nice." Izuku began, as he brushed a stray lock of blonde hair away from Toshinori's face. Their relationship was now extremely intimate and tactile – something he noticed they only had with each other. Like him, Izuku shied away from touching others. Which was odd considering how touchy the teen was with him (not that was complaining – he rather enjoyed being favoured by Izuku) "It feels as if I am providing… That I'm useful and have purpose. That I am helping and comforting. It feels as if I am wanted and needed… It makes me feel cared for, loved and adored unconditionally."

Feeling the pad of Izuku's finger lightly brush against his lips, and Toshinori pressed a soft kiss on the appendage, "When my milk lets down… a haze comes over me. The feeling of you pulling the milk out of me is pleasurable and… right? It feels right. Everything wrong just goes away and the world calms down. I feel more focused and happier. I feel better."

They still couldn't voice what they each felt during these feeding sessions. However, they both knew they were feeling the same thing. Although this activity began as a mutually beneficial arrangement (Izuku being drained and Toshinori's health improving), it had now developed into something deeper – something more. Ever since he began nursing from Izuku, he felt their relationship had become tighter and more entrenched. It was as if they were constantly trying to live in each other's space and any gap between them ceased to exist. His bond with Izuku was resolute and irrevocable.

And Toshinori knew Izuku had felt the same.

He had often worried about being left behind once his predecessor had surpassed him, but now he knew Izuku needed him, just as much he needed Izuku. Thankfully, they were known to be close; hence this shift was easily accepted among their colleagues without many comments. However, they made sure to limit themselves in public until Izuku graduated. Something they had tried to implement, but Toshinori was an extremely jealous, possessive and selfish man.

As All Might, he was epitome of selflessness and generosity; but as Yagi Toshinori he was none of those things. He guarded what was his intently, and Izuku was his. He had tried to give Izuku space, but every time he moved away from the teen, there was always another eager to enter to replace him – to take Izuku away from him. After one of his lessons with Izuku's class, he nearly summoned the remaining power of All For One in order to put Todoroki-Kun through a wall. Not that he was a violent man, Toshinori's moods were usually farthest from anger; but this particular student had decided to confess to his Izuku. Thankfully, Izuku had declined confession; for Toshinori hadn't known if he could let the teen go – to break their bond and have another person drink Izuku's milk. To allow another person to feel all that love and care in Izuku's embrace. He couldn't accept that fate nor would he allow it. He was finally appreciated and adored for himself – how could he let go of happiness when he finally had a chance to experience it?

Izuku must have known he had been eavesdropping on the confession, for the teen hadn't commented on his subsequent foul mood for the rest of the day or his increased neediness during the session. As he was nursing, he heard the younger male whisper quietly in his ear as he drank. How he could never leave Toshinori. How much he loved him and loved being loved in return. How happy he was having Toshinori in his arms and feeding from him. How Toshinori pampered him afterwards. How he couldn't imagine anyone else at his breast. The trust they built could never be replicated with anyone. That he wouldn't share this with anyone.

"Easy Toshi..." Izuku's voice whispered, cutting through his thoughts. "I'm not going anywhere. It's all for you." Gently running his hands through the blonde mane.

Toshinori gave the suckled teat a kiss of apology before resuming his nursing. He must have increased pressure unconsciously thinking back to that particular memory. Izuku probably sensed the neediness behind the harder tugs and chose those particular words to sooth him. Humming at the perceptiveness of his partner, Toshinori nuzzled Izuku's breast who in turn tenderly stroked his face as he traced the sharp bony features with his fingers. Toshinori didn't have to open his eyes to know the younger male was now smiling fondly at him. He could feel it in the weight of Izuku's gaze.

Sensing the skin around the breast softened as the milk he pulled decreased with every suckle, Toshinori opened his eyes. The tightness around the teat had gone and he could see the subtle difference between a full leaking breast and drained one. Although even at bursting, Izuku's chest didn't resemble that of a woman's. It was fuller when compared to some of his built classmates, but nothing out of the ordinary. Even as the quantity of his milk had increased over the years, the only tell was the tightness of the skin and occasional redness. However, they would regularly nurse and moisturise to keep any negative effects such as stretch marks from appearing. Izuku even had his costume altered to include a padded undervest to give support and prevent leakage during missions or spars.

Once he'd completely drained the breast, giving it a couple of extra tugs to make sure, Toshinori kissed the wet nipple as thanks (Izuku always let out a small huff of amusement at that) before rearranging himself to the other side. Due to lack of attention, the breast had leaked out a little tickle of thin white milk. Using his tongue, he traced the line of milk from the teen's stomach up to his nipple. Again, wetting the nub before sealing his lips around it and suckling gently. As before, Izuku let out a pleased sigh of relief as the milk let down and flowed into Toshinori's mouth.

Keeping the suction light at the beginning, as anything harder would only cause discomfort for his partner; Toshinori allowed himself once more to be lulled into the intoxicating feeling of being loved and protected. Everything about this moment was soothing and full of contentment. If he could choose a way to pass on, it would at this moment, in this position. There was something about being in Izuku's arms and being surrounded by his scent, which made him feel relaxed and safe; even if the world was ending tomorrow, Toshinori felt absolutely at peace.

Feeling his belly fill with warm milk and settling comfortably inside him, Toshinori nuzzled closer. Izuku hummed light as he continued to run his fingers through his hair. He felt the teen taking one of his front longer bangs into his fingers and heard a soft kiss pressed on it. Peering open his eyes, Toshinori met Izuku's green with his blue. Seeing the tender and nurturing smile on the teen's lips, he closed his eyes once more as he returned his attention towards nursing the breast. As he was in the rhythm of matching breaths and heart beats, Toshinori heard Izuku begin to whisper.

"I don't understand why you hide Toshi." Izuku begins, "You are beautiful. Every part of you is amazing and wonderful… Yes, All Might may have caught my attention initially, but what made me fall in love was you, Toshi." He could feel Izuku trace the scar on his side, "I don't know why you feel ashamed of this. It is proof of your inner strength and perseverance. It's proof you survived and you came out on top… It should be a badge of honour and worn with pride – I am certainly proud of you." Feeling teen's hand return to stroking his hair, "Thank you for choosing me, thank you for allowing me into your life, thank you for granting my dreams and giving me happiness."

Izuku slowly shifted and bent down gently, placing a soft kiss on his temple, "I love you Yagi Toshinori."

Toshinori felt tears collect behind his closed eyes and leak out, followed by the feeling of Izuku brushing them away. Tightening his embrace around the smaller male, he allowed himself to be weak. In Izuku's arms he didn't have to worry about keeping up a front. He was safe and protected. He was loved and adored. He was wanted and needed.

All Might may have had the world, but Yagi Toshinori had Izuku.

The world wanted Deku, and Toshinori was fine with. However, Izuku belonged to no one but him. Just as Toshinori was Izuku's.

Allowing the feeling to wash over him, Toshinori continued nursing until he felt the breast empty as the milk dried up. Suckling a little more to ensure he had drained it entirely; he placed a soft kiss on the abused nub before moving to capture Izuku's lips into a deep kiss. This time the teen's tongue entered his mouth, obviously tasting his own milk as they explored every inch of Toshinori's mouth. Moaning lowly, he allows Izuku to take over the kiss.

Not breaking the kiss, the younger male gradually shifts their positions; now Toshinori was laying on his back with Izuku draped over his front. Parting his thighs, the teen places them on either side of Toshinori's waist and grinds their erect cocks together in a slow sensual circle. He moans into Izuku's mouth at the new sensation, and his hands automatically went to the teen's plump buttocks. Squeezing the flesh and pulling the teen towards him in an attempt to increase the pressure of Izuku's groin on his; Toshinori hears a soft giggle.

"So impatient." Izuku whispers out, breaking their kiss to place a soft peck on his nose, "Let me love you, Toshi."

He couldn't keep the pout away from his face, and Izuku laughed softly once more before leaning down to suckle on his protruding lower lip. Toshinori hummed with pleasure as he relaxed his jaw, allowing Izuku in again – but this time he pressed back. No matter what size he was, Izuku always felt small in his hands. Gliding his hands from the teen's ample bottom upwards, he traced every muscle on Izuku's back. Fingers tips dipping into the divot of the teen's spine and dragging his nails upwards to the base of his neck, then gripping the back of it firmly; Toshinori watches as Izuku's body shivers in response, letting out a soft gasp of desire.

"You are playing dirty, Old Man." The teen whined petulantly, and Toshinori grinned mischievously in return. Few months ago, when they were having sex, he discovered Izuku had an off button. He found firmly gripping the teen from behind his neck would cause Izuku to immediately become docile and susceptible. Watching those green eyes fog up with arousal, Toshinori released his grip, causing the teen to regain focus.

Clearly annoyed at being one upped, Izuku instantly takes his wrist and pins them above his head. Grinding his hips harder against Toshinori, the teen whispered in his ear coyly, "Two can play this game."

Toshinori lets out a low groan – he loved it when Izuku became assertive in bed. Surprisingly, there wasn't any awkwardness or discomfort as their relationship became sexual in nature. They were already comfortable being naked in front of each other and the lull of nursing always kept them calm as their touches took on a more sensual route. Toshinori had many partners before Izuku, and none of them made him feel this confident and assured in bed. Izuku himself was considerably proactive despite being inexperienced.

Showering Toshinori's neck and shoulders with soft kisses (occasionally sucking down to leave a hickey or two), Izuku releases the grip on his wrists. The blonde sighs at the feel of the teen's smaller hands flitter slowly down his arms – feeling every muscle and bone in his limbs as they made their way towards his chest. Deliberately Izuku shifts downwards as the teen continues to kiss and lick every part of Toshinori's chest and torso. Light fingers mapping ever grove and dip of his body, the blonde shudders at the attention lavished upon him. Toshinori chokes back a low whimper as he feels Izuku's wet warm tongue trace the outline of his scar. His skin was extremely sensitive around his old injury and his student knew that very well – the little minx.

However, he couldn't find it in him to be annoyed. For years of being ashamed and insecure of his true form (hiding it from the world), Toshinori almost couldn't believe being accepted and loved unconditionally in it by anyone. He knew the feeling of being adored and desired, but that was as All Might. Until now, he wouldn't have even considered anyone desiring him as Yagi Toshinori. Yet here he was, every inch of his true form being worshipped by the person he had come to love greater than life itself.

"I love you, Izuku." Toshinori blurted out, unable to contain his feelings. Meeting those clear green eyes, he continues, "God – I love you so much… Where have you been all my life? You have no idea how much I need you. You have no idea how much I want to keep you beside me – to keep you in my life… Please don't leave me. Please say you will stay forever."

"Always, Toshi." Izuku promises resolutely, as he shifts upwards to press a small kiss on Toshinori's lips. "You are my home, Toshi. I will never leave my home."

"God, you are perfect." He sighs in response as they pressed their foreheads together, allowing the emotions to settle.

Once the intensity of the feelings faded away, Izuku pressed another chaste kiss on his lips before returning to his previous position. Slightly softened due to the sudden burst of emotions, Toshinori felt Izuku pump his cock a few times before sticking out his tongue and licking a dripping pre-cum from its head. The suddenness of feeling the sensitive head being sealed by a warm wet mouth, made Toshinori arch his back as he gasped loudly in pleasure.

Instinctively, he reached out to teen and buried his hand in those soft green curls. Grasping lightly as he felt Izuku's tongue swivel around the head of his cock; slipping the tongue between the glans and foreskin. In his youth he'd considered circumcision, but now he was grateful for not going through with the surgery. If he had, he wouldn't have been able to experience Izuku's talented tongue (who knew all that mumbling made the teen's tongue considerably dextrous and agile). Bucking his hips involuntarily, as Izuku's tongue began stroking his frenulum whilst hollowing his cheeks to increase the suction on head.

Lifting his head up, Toshinori peered lustfully at his protégé as he saw (and felt) his cock inch by inch being fed into Izuku's mouth. Seeing the saliva seep past those reddened lips and wet his cock, making it easier for Izuku to glide it in and out of mouth. Tongue swirling around his length and occasionally hollowing of cheeks as the teen's head bobbed up and down. Everything about it was dirty, slick and sloppy; and Toshinori hadn't wished it any other way. Jerking slightly at the warm touch on his balls, Toshinori watched intensely as Izuku's mouth lifted off his cock with an audible wet pop and a string of saliva connecting the head to the teen lower lip. Shuddering at the erotic sight, Toshinori cried out as he felt a familiar warm slick mouth on his balls. Izuku continued to pump the blonde's drenched cock, as he engulfed the balls with his mouth and rubbed them with his tongue.

Unable to handle the intensity sensation, Toshinori gripped Izuku's hair and lifted his head up. Seeing the debauched expression on the teen's face was beyond what he could handle. Lips darken and wet with saliva, Toshinori shuddered with arousal at the sight. Noticing the slight furrow of his student's he explained patiently, "I'm not going to last if you keep doing that, Izuku."

Seeing the light annoyance melt into a pleased look, Izuku wiped the saliva dripping down his chin as he gestured to the bedside drawers, "Then let's move this along."

Chuckling at the coyness displayed, Toshinori reaches out and pulls out the bottle of lube they kept there. Handing it to the teen, as he observes Izuku squirt some on to his hand and finger himself open. He would have offered to prep the teen, but seeing how erect and red Izuku's cock was, Toshinori safely assumed he wasn't the only impatient one (maybe next time he could eat Izuku open – the teen loved when he played with his opening). Seeing his partner shift forward, knees on either side of Toshinori's hips and lifted up as he rubbed the remaining lube on his larger cock. Helping Izuku in holding the position, by placing his hands on either side of his smaller hips; Toshinori watches intently as the teen positions his cock at his hastily prepared opening.

Gritting his teeth as Izuku begins to sink slowly on his length, Toshinori drinks in all the expressions that flutter across his student's face. He was concerned with lack of prep but seeing the absolute bliss on Izuku's face as his cock disappeared into him would always reassure him (the teen once explained that he craved the burn of the initial stretch would give as it made the experience more intense). Feeling his length slowly being engulfed in a tight wet and slick heat almost made Toshinori lose control. Once Izuku was fully seated, they both remained still – obviously trying to regain control over their building orgasm.

"Fuck." He swore, "How are you this tight?"

"Cause you're so fucking big." Izuku shot back, not missing a beat.

Toshinori preened slightly at the backhanded compliment. He would have argued that he was only proportionate, but having Izuku moaning while seated on his cock took all logical thought and speech away from him. Allowing the teen to adjust, Toshinori rocked his hips slightly causing the younger male to shudder at the movement.

After a few moments, Izuku gently lifted his hip; pulling away from his cock before lowering back down again. Toshinori grunted at the drag of teen's tight wet heat moving up and down. Tightening his hold on Izuku's hips, he helped his student in riding him. Letting his eye roam lower, he noticed the slight bounce in Izuku's breasts (perhaps he should try fucking before a nursing session, he would love to see the milk squirt and dribble out from the motion). Gradually the thrusts became faster and harder, and he guided the teen in changing his angle until he found the one that caused Toshinori's cock to brush against his prostrate. Toshinori jerked violently when Izuku clamped tightly around his cock – almost making him cum prematurely.

Toshinori growled as Izuku bobbed a few more times, moaning lewdly as he bounced on the blonde's cock. Sensing the strain of holding this position, he lifted the teen off his length and flipped Izuku face down on the bedding. Raising the younger male by his hips to his knees, Toshinori roughly re-entered the teen from behind. Gathering the excess lube around Izuku's opening on to his palm, he leant forward and began pumping his student's much neglected cock as he started to thrust from behind.

Hearing the green haired teen writher and mewl with every thrust – pitch climbing as he increased the speed and strength. Izuku keened out his name as he begged Toshinori for relief. Captivated by the sight of his student grasp frantically at the sheets and tighten around him as he continuously rammed into the teen's prostrate. Feeling the soft slick muscles squeeze his length as he pumped in and out of Izuku was overwhelming. Sensing his partner's climax building by the tensing of the teen's muscles and tightening of around his cock; Toshinori leant forward, draping himself over the smaller male's heated body. A couple of thrusts and pumps of Izuku's length, and Toshinori soon found the teen clamping tightly around his cock in a vice like grip as he felt his student climax in his hand; crying out his name.

Rutting against the shuddering form below, Toshinori chased his own release and rasped out Izuku's name as he came. Collapsing to the side, taking care not to crush either of their limbs; they remained as so till their breathing returned to normal. Toshinori tenderly brushed the sweat soaked hair away from Izuku's eyes as he pressed a soft kiss on the teen's temple. Izuku smiled fondly and hummed lowly in response as he burrowed into Toshinori's warm embrace. Clearly enamoured and hormones flooding his system, Toshinori tightened the arms he had around Izuku; gently sucking a mark on the teen's neck – behind his ear and below the hairline (just out of sight).

Although they couldn't go public with their relationship as of yet, Toshinori still wanted the world to know Izuku was taken. Even if he couldn't claim the teen now, at least the presence of these marks would deter any other potential 'annoyances' from approaching his student.

Once he felt himself become soft, Toshinori slowly pulled out of the teen causing Izuku to release a low whine of disappointment at its loss. Seeing his cum trickle out of the teen's swollen rim, he couldn't suppress the urge to reach in and scoop the slick white liquid and press it back in. Whimpering at the sensation of having Toshinori's cold fingers against his redden opening. Logically he knew Izuku would clean himself afterwards, but he often fantasies about keeping the teen full of his seed. Perhaps it was possessiveness that made him want to claim Izuku in every way possible.

Reaching out once more to the bedside drawer which held the lube, Toshinori pulled out a packet of unscented baby wipes. Taking a couple to his hand, he returned his attention to the dozing Izuku and began cleaning the teen. The younger male remained soft and pliant in his arms, as he wiped away the mixture of sweat, dried saliva and cum from their groins. Sighing softly at his touch, Izuku nuzzled into him at the pampering – he always loved it when Toshinori showered him with attention.

"So, what's for dinner?" Toshinori asked idly, turning his attention towards Izuku.

The teen raises a single eyebrow in disbelief, "You cannot be hungry already."

"Well… For your cooking." He smiles playfully, "There is always room."

"That's what you said about my milk."

"Oh, did I?" Toshinori teased as his thoughts drifted to the small velvet box he kept tucked away. Izuku's graduation was a few months away, and he had an important question to ask him after the ceremony.

A/N: So… Yeah… I haven't written smut given my past few fics, and with all the whump happening for October; thought we needed some soft sappy sex to balance things out. Not to mention a hefty serving of TLC for our two beloved leads.
