Trouble...or is it?

The next day was a flurry of activity.

Deku was recognized on the train, and congratulated. She had more pros interested in her for internships than almost anyone else in the class. Only Todoroki had more, and even that was close.

The class picked hero aliases, for the most part. A few people stuck with their actual names, for now. Deku stuck with her newly accepted nickname.

They were given the information of their potential recruiters to look over and choose from. A few students were given a generic list...those who hadn't received any special attention during the festival.

Later, as Deku was considering her options at one of the tables in a study room, she was again interrupted by a familiar voice.

"Midoriya?"

She looked up from the stack of papers into the nervous face of Jiro. "Jiro? Is something wrong?"

"I wanted to talk to you...about um...the sports festival."

"Ok...what's wrong?" Deku had a bad feeling...

Jiro took a deep breath. "I...I heard your conversation with Shiozaki. During your match."

Deku paled. "W-what...?"

"And I...I wanted to know what had really happened...It scared me a bit. So I...sortof...spied on you. Afterward, when you left the clinic."

Deku was stunned. Visions of various worst case scenarios filled her head.

"They said they knew how it worked...I've only figured out pieces of it, but you must have used your quirk with them too, and...it does something to people...sexually...? But you have multiple quirks, from both of them, and more...how many people have you done this to?"

"It's...it's complicated. Most of them were accidents. The others were...special circumstances..."

"How many?"

Deku paused. "Seven..."

This time it was Jiro's turn to pale. "S-seven? Are they all our classm...no, there was the spider quirk..."

"The first three happened when I was still learning about my quirk. It was...a late onset. I've only had it for less than a year. Two of those were completely voluntary. Only the first wasn't. And since I've been here...Two people approached me first. You already know what happened with Shiozaki..." Deku trailed off.

"That leaves one more..."

"I...right...well...you see, my quirk affects me, too, to an extent. And...there were extenuating circumstances...I regret what happened..."

Jiro practically whispered. "Bakugou?"

"H-how?"

"You used his quirk. And he seems to practically hate you, so he didn't approach you willingly."

"I..."

"He's also an ass."

"That doesn't...I mean, I still shouldn't..."

"No..." She paused for a long moment. Deku wasn't sure what part she was objecting to. "Tell me how it works."

"But..." Deku objected.

"Tell me." The response was icy.

"I'm sorry...it's not that I refuse, I just...Its not all my secrets to tell. I need to...process. But if you know this much..."

"I'm trying to give you the benefit of the doubt, you're not the only one in class with a frightening, abusable quirk. But I can't let it go until I understand."

So Deku explained. Not quite everything. She left out her origin, and names of the people she'd been with, though that was mostly a technicality. Jiro knew most of the quirks she'd displayed and so could piece the rest together fine, like with Bakugo.

Jiro's expression was easily readable throughout the explanation, getting steadily wider eyed with every new revelation of her abilities.

When she reached the end of the story, Jiro's expression became stony. Deku was certain she was about to denounce her, declare her a ****, or even attack her.

Instead, one of her ear jacks moved, pulling something it was plugged into out of her pocket. Deku realized instantly that it had been extended down her back, and she'd missed the small segment going to her pocket.

Now in her hand, it was clear the object was a cell phone. She held it up to her ear and spoke. "I believe her. Thank you. I'm going to talk to her privately now." She withdrew the phone and pressed a button, presumably hanging up, before unplugging and returning it to her pocket.

"W-what?! Who was that?" Deku paled more.

"I was scared of you...You honestly think I'd come here without telling anyone?" She shook her head. "But the fact that you did and still haven't tried anything helps me feel better..."

Jiro stared her in the eyes. "I..." Another deep breath. "I want in."

"You what?!" Deku blushed.

"ssshhhh. I...look, this is embarrassing but..." Jiro blushed heavily. "...a-and I don't want to get you in trouble with anyone. I don't know your relationships or rules. You can say no. This isn't ****. B-but I..." Yet another pause and a deep breath. "...I've fantasized about having a cock...And I um, I'm bi."

Deku's blush deepened. "You realize...how much..."

"...power this would give you over me?" Jiro whispered back. "Yes. I'm sure." Her voice had gone timid. Like she'd expended all her confidence on the first half of the conversation, and was running on fumes now. She waited, fidgeting, for a response.

"Ok...but not here...I've...already gotten caught once this week." Deku blushed deeper again at the memory of Shiozaki walking in on them.

Five minutes later, They were making out in a bathroom. It hadn't been Deku's intent, but as soon as she'd revealed she didn't want to risk pregnancy because her quirk made her extremely fertile, Jiro had basically jumped on her. "Fine. But then I want something else."

She stepped back and then began to strip out of her clothes.

Deku tentatively did the same.

Jiro's eyes widened even more as her cock came into view. "H-huge..."

"You don't have to do anything to it...if you don't w..."

"I do...oh god, I do." Deku could see how wet she was, her lips puffy and glistening.

She stepped forward again, and directed Deku's cock to her moist lower lips. "H-hey...I said..."

"I know...but as long as you're not already about to blow on me, it'll be fine...ok?"

Deku nodded, nervously. Jiro moved, and Deku sank quickly, but not fully, into her slit. Both girls moaned loudly.

Jiro shuddered. "Oh god...sso big." A few months ago Deku would have thought she'd just cum, but...apparently not yet.

She began to roll her hips, sinking deeper on each thrust until the thin girl was enveloping almost her entire cock. She wasn't as physically small as Tsuyu, but somehow much tighter.

Deku moaned. "I'm not going to last very long like t-this Jiro. I haven't...ddone anything yet today. I normally...three or four times."

Jiro nodded, and on the next bucking of her hips, pulled all the way off, and turned around...and sank herself down onto Deku's now slick cock with her ass.

The sudden tightness caught Deku off guard. She felt herself losing control she thought she'd managed to reclaim over the last few weeks, and began firing ropes of hot cum into Jiro's bowels.

Jiro moaned. Shuddered again. She waited a few moments, then began to hump. Deku half expected her to cum in that moment too, but...anal wasn't like in porn, she supposed.

But she could tell the girl was loving it, despite the discomfort the huge tool must be causing.

It took some time, but she got there, after a few minutes of thrusting. Deku felt her shudder again, clench...and then she felt the telltale sign of Jiro's quirk shifting, and also another sensation she couldn't quite place, and she decided to try something, shifting Jiro's quirk to her own, Harem, before the orgasm even finished.

Her breasts ballooned out, smaller than the other girls in this form, but still more than double their previous size. Deku couldn't see her cock, but from the way she suddenly grasped in front of her she could tell it worked.

Then the bathroom door slammed open along with another familiar voice. "Jiro!"

A/N: For anyone who cares about "canon" shipping, I want to say that there is room in this story for Deku to share. Other pairings can still happen, especially if Deku chooses not to push. The addictive qualities are weaker if Deku isn't actively wanting to push the relationship, and can be overcome. And other guys or girls can still have some fun without stepping on Deku's toes, because of how many people she's ending up with.

I say this because I know one of the more popular shipping pairings in the fandom is Jiro/Kaminari. So don't see this as shitting on that. Not everyone Deku is with has to consider her their one true love.

I think I've decided on the hero internship for Deku, and I think it'll be pretty interesting, because it drastically changes the next arc from canon. On the bright side, we'll be getting a bit of background info about things that have changed outside Deku's immediate circle of influence in the next couple chapters, so look forward to that! I won't spoil too much, but the journey through the next arc may be a little shocking, but I urge you to see it through.
