After their discusion Izuku received a text from his mom, she was getting worried with how late it was. So Eraser Red said goodbye to the boy and said they would meet the next day at Dagoba Beach.
''Wait!'' Eraser said just before Izuku had reached the street out of the dark alley. ''I forgot to mention something really important about Pokémon. You see us like most living creatures, they can reproduce thanks to breeding and-''
Izuku's face suddenly turn red as soon as he realised where the conversation was going. ''I-I know how the birds and the bee work thank you very much, bye!'' With the speed only a teen trying to get out of an awkward situation could acheive Izuku bolt out toward his home leaving a trail of dust behind. His Eevee had no trouble keeping pace with him despite that.
''Wait it's really important!...Damn problem child, he's going to get caught with his pants down, literally.'' The tired man muttered before giving up and went to start his nightly patrol.
Izuku felt the tension in his shoulders lift as he finally arrived back home. It felt like an eternity since he had been back home and yet he had only left this morning. Today had the been the longest and most exhausting day of his life. But at least what had started as the worse day ever had taken a turn for the better in the end.
''I'm home!'' Izuku called out. His mother came into him like a green tornado.
''Oh Izuku! I was so worried! You never stay out this late usually!'' Inko hugged him until his bone creaked as the infamous Mydoriya's tears leaked out of her eyes.
''Veve?'' The brown furred Pokémon called out worriedly when it saw that it's master was beginning to turn a shade of purple.
Izuku took a full lungfull of air when his mom finally released him from her death grip. She glanced down toward the small fox with confusion.
''Izuku you know that our landlord doesn't accept pets right? And no offense but I really don't recognise what sort of animal that is.'' Despite her admonishing tone Izuku's responded with a blinding smile.
''That's not a pet mom it's my quirk! The Pokéball finally opened today and Eevee came out of it!'' Eraser Red had been the one to mention what the name of the ball was, it was relieving to at least have a name for what the object was.
Inko eyes got teary all over again. ''Your quirk finally truly manifested itself, I'm so proud Izuku!''
''Eevee!'' The small fox couldn't help but yelp in concern when it's master was once again put in a death grip by his mother.
That night to absotulely no one's surprise the Midoriya made Katsudon to celebrate the awakening of Izuku's quirk. Izuku didn't really know if awakening was really the appropriate term since it's still felt like his quirk had so much left to be discovered, but it was close enough he supposed.
Then Inko bid her son goodnight and he and his new partner went to his room. Izuku went to undress but felt a bit awkward when he realised Eevee was starring at him. ''Umm, can you turn around please?'' He knew it was silly despite what he had told his mother Eevee was kind of like a pet and pets really didn't care about silly things like nudity.
But at the same time he could see the raw inteligence in Eevee's eyes that a normal pet just wouldn't have, if Eevee wasn't sapient it was extremely close to it. The brown furred Pokémon turned around at his request, much to Izuku's relief.
He proceeded to tear his shirt and put his much comfier baggy shirt. Then he pulled down his pants along with his underwear. Before he could reach for his pair of boxer he felt something small and furry tackle him.
Izuku let out a small yelp as he was sent crashing down on his matress with no pants on. Eevee quickly jumped on the bed with him and the flirtatious expression on it's face sent shiver down his spine.
Eevee paused in it's advance and winked seductively at him and somehow pink heart-shaped lights formed from it's gesture and went straight toward Izuku. The boy tried to get out of the way but it was arleady far too late. The lights converged on him and his vision started to blurred as he felt a spell of dyzziness invade his mind.
But as soon as it came the dizziness vanished and he noticed that Eevee was standing right between his legs and for the first time since he knew the Pokémon he noticed it's vagina which was arleady gleaming with wetness. So she was a girl then and what a beautiful girl she was.
Instead of being mortified by the sight as he usually would, he found that he couldn't tear away his eyes from it and the rest of the body of his Eevee. He also noticed her beautiful magenta eyes looking at him with clear need and lust and found that he couldn't help but cave in to her demands.
''You are so beautiful and cute Eevee. I am yours now and forever.'' Izuku said with a stupid grin on his face. Wait why am I so suddenly attracted to her. Did that weird attack do something to my head, oh well it's not like it matter. Izuku tought to himself despite a small part of his mind screaming at him that it did matter.
''Eevee!'' The brown furred fox responded enthusiastically before she lowered herself and started to gently grind her pussy against his still soft but slowly hardening member.
A small part of his mind, the only part that hadn't been affected by the Eevee weird ability from earlier told him that this was wrong, she was a pet she shouldn't have sex with him in any circumstance.
But the vast majority of his brain screamed at that small part and told him to look at Eevee at how inteligent, beautiful and just how happy she looked to be doing this with him. What right did it have to take this away from their precious princess?
The small part of his mind guilty at considering his companion like a simple animal fell silent and let himself be absorbed with the lovestruck majority of his mind.
By now Izuku's rod was fully errected and Eevee wasted no time to swallow it whole between her lower lips. Eevee let out a pleased moan as her pussy was streched wide open by her master's cock. And much to Izuku's amazement he realised that her pussy wasn't even fully streched despite the massive size difference between them. Just how much could Eevee's pussy stretch? And what was even more intriguing was the fact that even thought he could tell Eevee could stretch further, her pussy still felt really tight.
As he would later learn Pokémon pussies in general were frankly impossible. It was as if they were bigger on the inside or something because even something like a small cat Pokémon was able to mate with a massive whale according to previous people with the Pokémon Trainer's quirk. Izuku's dick was truly nothing compared to what Eevee could handle.
But right now he didn't know any of that. Right now Izuku was waging a war against himself. Eevee's wet and warm vagina just felt too amazing on his cock and while he put a valiant effort to last, Izuku was still a virgin. And so when Eevee slammed down on his crotch and her bottom lips pressed tightly around his inexperienced rod Izuku had to burry his face in his pillow as he came hard inside, filling her womb with his warm sticky seeds.
It was then that Izuku realised that Eevee could control her own pussy like no human girls could. Because as he came inside her, her labia move as if it was sucking his penis dry of all the semen it could, he nearly came a second time from the sensation it inflicted upon him.
Eevee did not have the chance to come herself, but she was still satisfied with with the fact she had the chance to take her master's virginity and become full with his cum. She let his dick come out of her snatch with a 'plop' and proceeded to go give Izuku a short but sweet kiss right on his lips before she flop down beside him and both of them fell unconscious into a dreamless sleep...
Izuku nearly had a mental breakdown when he awoke the next day and realised just what he had done with Eevee last night. Despite the fact that Eevee had clearly been the one to take advantage of him he felt like it was still his fault.
Maybe if he had stopped being embarassed and actually listened to what Eraser Red had to say this wouldn't have had happened.
What scared him off the most about all this as he stare at the content face of Eevee was that the affection he had felt last night was still there. Just not as strong as it had been after the move she had used on him. And what was the worse in all this was that he honestly could say he wouldn't mind if Eevee did what she did last night again, in fact a part of him was hoping she would do it again, what was wrong with him?!
He really couldn't bear to look at Eevee right in the face with all his impure toughts running in his head. So with resignation he extended his hand and summoned Eevee's Pokéball in his hand before pressing on the button and absorbing her back in her ball in a red beam of light.
A small irrational part of him was scared that Eevee wouldn't come out of her ball again just like before. Another part told him maybe he deserved it after what he had allowed to pass last night.
He took a quick shower before dressing himself up for the day and after a short breakfast he left for Dagobah Beach after leaving a note for his mother saying he would be gone for the day...
As he arrived he could see that Eraser Red was arleady waiting for him with a cup of cofee in his hand. ''I hope you're glad I'm doing this for you problem child, I should be at home sleeping right now.''
''Y-yes sir!'' Izuku replied whiled bowing stiffly. ''S-so what exactly are we doing here?'' He asked while glancing at all the trash around them. He really hoped his new teacher wasn't expecting him to do something insane like clearing this whole beach of trash before the entrance exam.
In another location All Might suddenly cough blood. ''...Weird I'm not even close to my limit.'' The number one hero stated with a baffled look.
''As I said yesterday, exposing yourself as a Pokemon Trainer is really dangerous. Because of this there's really not a lot of place where we can train without risks. But this place is perfect, no one will come to disturb us here. First thing first, you should get yourself familiar with your Pokémon. Learn what moves it can do and what are their strong and weak points. We can use all the trash as target practice.''
Izuku nodded in understanding. ''Alright.'' Eraser started. ''Call out your Pokémon so we can start.''
Izuku made the familiar gesture and summoned the Pokéball in the palm of his hand. But he hesitated before pressing on the button to release her something that Eraser immediatly noticed as he sighed.
''Your Pokémon had sex with you last night.'' It wasn't a question but despite that Izuku froze up and his whole face turned into a tomato. The tired man sighed. ''I wanted to avoid this if possible but I can't say I'm surprised you should have listened to me last night instead of just running away.''
The green haired boy lowered his head in shame. ''I'm sorry I'm a horrible person for allowing this to happen.''
Eraser Red rolled his eyes. ''Don't be so dramatic problem child. I knew this was going to happen eventually I just wanted you to be more prepared for it. Pokémon are amazing creatures but they do not share the same morals we humans have. Things like conscent and rape are alien concepts to them. When two Pokemon of opposite genders meet each other it's just an accepted fact that both of them will fuck each other brain out before the day is out. Hell it tend to happen even when both of them are the same gender. Unfortunately they think humans function the same and want to have sex with us too and that tend to create many awkward situations.''
Izuku's was red as his new teacher casually talk of such a crude topic, but there was something he wanted to ask despite how embarassing it was. ''So Pokémon only want to m-mate right? They don't really have r-romantic feeling for each other?''
Eraser shook his head. ''Pokémon can fall in love and it happen fairly often. However Pokémon don't believe in monogamy. Romantic couple will often seek other Pokemon to mate with them all at the same time. So if you fall in love with your Eevee don't expect her to stay loyal.''
Izuku spluttered in a panic. ''W-what?! Why would you think I-I would ever fall in love with a P-Pokémon, ridiculous!''
''I can arleady see you're starting to develop a crush kid, don't worry it's only natural to feel close to someone you did something so intimate with. Pokémon are not animals despite their non-human appearance. They are completely sapient. So from a moral standpoint it's really not so different to dating someone with a mutation quirk. And I'll leave you with a secret to make you feel better. I don't know a single person with a Pokémon Trainer quirk who didn't have sex regularly with their partner. It's just how it work with Pokémon.''
Izuku stared at him in disbelief and couldn't help but stare at the Pokéball hanging from the man's belt. Eraser Red rolled his eyes. ''Yes even me kid, despite her appearance Luxray is a diva. She won't fall asleep after a night patrol unless she has her way with me. When I'm really tired after a shift tough I tend to let Present Mic handle her.''
''P-present Mic the host of Put Your Hands Up Radio?!'' Izuku asked with stars in his eyes.
''Yes, that loudmouth. Anyway that make me think of what I want to mentioned to you last night. Pokémon want to mate pretty much on a daily basis, but sometime you just might too tired to handle it. What a lot of trainers end up doing is buying toys to keep them busy and satisfied.''
Izuku's face flushed once again. ''You mean like a s-sex toys?!'' He asked with a squeak.
''Yes kid, those. I would recommend vibrators in particular since you wouldn't have to masturbate her yourself you could just let the toy do the job for you. Also you should try to learn how to properly lick your partner's private areas, trust me it will save your life when your Pokémon goes into heat.'' As soon as Eraser Red stopped talking he heard a thud and saw Izuku on the ground. The embarassment had been so much that he fell unconscious.
Eraser sighed and facepalmed so hard it left a red mark. ''Why is it always the repressed ones that get a Pokémon? I swear it must be a divine joke.''
When Izuku finally regained consciousness he finally release Eevee out of the Pokéball. She immediatly proceeded to rub herself against his leg and looked at him with a look of adoration. But after that he convinced her to get ready for training and he ordered to show him all her moves.
They soon learned that all the moves she knew thus far were Quick Attack, Sand Attack, Attract, Swift and Bite. Eraser Red had been surprised, he told Izuku that usually it took some training before a Pokémon could remember more than four moves. The fact that Eevee knew five from the get go was impressive.
They practice most of the move until Eevee was utterly exhausted the only one they didn't touch further upon was attract for obvious reasons. However Eraser did give Izuku some pointers about the move.
''Attract only intensify the feeling you arleady have. So yesterday when she use it on you Eevee took the small unnoticable attraction that was budding deep inside you and bought it out in full force. Normally it would have probably taken months before you even noticed you had any romantic feeling toward your partner. The move cannot bring out something that doesn't exist. That is why when the move is used by a female Pokémon it is mostly use on male opponents to make them stop wanting to fight your Pokémon. Attract can work on females too if they are naturally attracted to other females. But it won't work at all on a straight female. That's why the move is deemed unreliable against the same gender.''
It was past noon when Izuku recalled Eevee inside her Pokéball But Eraser Red wasn't done with him yet. For the rest of the day he trained Izuku in hand to hand combat. The training was brutal and Izuku did not even manage to land a single hit on the pro hero the whole time they sparred.
After another painful hit Izuku was left panting on the ground. ''Why are we even doing this? Won't I use Eevee for all my hero work?''
Aizawa snorted at that. ''You won't always be able to rely on your partner for everything problem child. A hero can't be a one trick horse, otherwise they die.''
When the training had ended Izuku felt like every part of his body ached. As he entered back home he directly made his way back on his bed and fell on it and promtly fell to sleep.
He was woken up in the middle of the night as he felt Eevee tugged at his pants. The Eevee had a surprising ease at removing his clothes. As soon as his pants was down she soon disgarded his underwear too. Izuku should have put a fight but he was honestly too tired and sore to care and simply let Eevee have her way.
Izuku hadn't been affected by attract this time, but he would be lying if he said it hadn't felt good as Eevee's warm and slippery entrance welcomed his dick inside and to Izuku satisfaction he managed to last until Eevee managed to orgasm before he came himself this time.
The two of them quickly fell back into a comfortable slumber and it wouldn't be until the next morning that Izuku would question how did Eevee even managed to leave her Pokéball on her own.
So as you saw this fic will contain some smut scenes. Don't worry for the non-Poképhillia fans there will be scene between humans too. However I'm still not certain how frequent these smut scenes should be, so I guess I'll let you guys decide. Do you want more of this or less?
The horniness of Pokémon will be a constant, however I can make it happen more offscreen if you guys don't like it.
