Mostly good news.

Two days later, Dec 27th, Morning:

Aizawa was rubbing his temples again.

"Alright. So...you can give out your quirk, you can revoke Ms. Asui's quirk, and you can duplicate it yourself. But you weren't able to give Asui both quirks at once, even though you could have both yourself? Does that sum this up?"

"Mostly..." Midoriya said sheepishly. He wished he had Tsuyu here, but she'd already been with him half of Christmas day, and had other people in her life who'd known her longer to see.

"Nightmare. You're a nightmare. But this quirk...Alright, fine. This is getting increasingly complicated, but we're going to do a few things. I have three people coming over the course of the day. Two of them are volunteers who have quirks that they do not want, who have agreed to become test subjects. They know that this may be very unconventional and...several possibilities of what they might be exposed to in order to complete the process, along with a caveat that we can't guarantee results, and an NDA. We don't know yet what will be required, but I hope you understand that the upper limits of this quirk may involve recreating whatever you and Ms. Asui did together. If it comes to that, you need to decide what you're willing to do to figure out your limits, and what she will be ok with you doing."

Aizawa looked Midoriya in the eyes and continued. "If you decide it's not worth it...then the rest will all be down to the psych evaluation...which is what the other visitor will be doing."

"I...understand. I expected that and have already talked to Tsuyu" Izuku explained. "We...I need to find out what I can do."

"Alright. This isn't something we can, or would try to ****, but it does change how we have to proceed. The first girl should be arriving within the hour."

An hour an a half later Izuku was engaged in what, so far, would have been the most awkward sexual encounter of her life even if she'd had more than two previously.

Kimi wasn't exactly unwilling, but it was clear she was only in this for the results, and had just as little experience as Izuku'd had when she met Tsuyu, and it was just...well, awkward...

Plus, well, to be frank, her appearance was incredibly unnerving. Her quirk gave her a partial spider-like appearance, including five glassy black eyes and large spider legs growing from her back...fortunately, the majority of her anatomy was human.

She was currently giving a very half-hearted attempt at a blowjob, but she did seem to be warming up to the idea as it went on.

Aizawa had given instructions, since he'd, for both party's sakes, not be in the room. After each act, each threshold or milestone along the chain of acts Izuku and Tsuyu had done together, starting with simple skin contact and working up from there, Midoriya was to actively try to suppress Kim's quirk, and stop once successful.

So far, nothing had happened, and it was still going to be a while at this rate. Fortunately, as her pheremones worked, Kimi got more and more into it, so the pace began to pick up, and after a few more minutes, Midoriya blew a load in her mouth with a loud groan.

Unlike Tsuyu, Kimi couldn't keep up with the flood and pulled away, coughing, spilling cum down her front. She licked her lips and seemed pleased by what she found, and looked up expectantly while tasting more cum with her fingers. "Wow, is this really what cum normally tastes like?"

"I uh...wouldn't actually know."

"Fair enough...I just...heard it was bad, but you're really tasty." She seemed to realize her wording. "Y-you cum I mean...anyway...was that enough?"

Izuku concentrated for a moment, then shook his head when nothing visibly changed. "No. Sorry..."

"That's ok...I'm kindof getting excited to do more, honestly? I thought I was straight but you're pretty cute...would you be interested in doing this again if this works?"

"I uh...we'll see." Izuku blushed. "Next is well..."

"Sex?" Kimi giggled. "Sure. But I'll have to be on top." She motioned to the extra legs.

Izuku nodded "R-right" and lay down on the bed. Fortunately her nerves didn't impede her performance any, and a few seconds later Kim was lowering herself onto the huge cock slowly.

"Ohmigod...it's too big." Kimi moaned. "I don't...think I can..."

"D-don't overdo it. You don't need to go all the way down." Midoriya warned.

"I...oh god I'm so full." The spider girl began to slowly work her way up and down, sinking a little lower each time.

Izuku joined her in moaning, but unlike Tsuyu, this time it was Kimi who went off first.

And she almost immediately collapsed much deeper onto Izuku's dick, as her extra legs, which were holding much of her weight, retracted suddenly back into her back, and her eyes shifted into rather pretty green human eyes.

The sudden deep thrust and the clenching of her pussy, along with the surprise, was too much, and Izuku found herself firing off just seconds behind Kimi, who only moaned in response.

A few dazed seconds later, she blinked and began feeling around her face. She rubbed at her eyes and blinked more, then felt around on her back. "It...it worked!"

Tears ran down her face, and she pulled Izuku into a hug. "Thank you so much. Thank you thank you thank you."

"Y-you're welcome. We should clean up, unless you need to rest for a minute."

"Mmm, are you sure? I still have one more place you haven't tried, cutie, and I owe you so much for this." Kimi grinned.

Midoriya gulped. "N-no, I...No, thank you, but no. It's...complicated."

Kimi sighed. "Oh alright...I hope I was able to help you with this test at least. And at least let me give you my number in case you change your mind."

An hour after that, Kimi was gone, and they'd worked out a few more details about this quirk. She could share any quirk she imprinted with anyone she imprinted...and after a quick call with Tsuyu, it was confirmed it worked at a long distance.

"Alright, one more test, and this time you'll be skipping most of the steps from last time. You know what the trigger seems to be, test that." Aizawa sighed.

Kin was much less...tentative than Kimi had been, at least at first. I may have helped that Izuku wasn't asking her to do anything except let her touch.And touch she did, starting by fingering the girl, whose quirk apparently involved luck. specifically, she stored up luck by causing passive minor bad luck around her, and then could unleash it to provide herself or someone else with a proportional, but usually small, spike of good luck.

Fortunately, nothing went wrong during the testing, and it wasn't long at all before Kin was without a quirk...and a few minutes later, was helping to test, via a call with Tsuyu, whether the two of them could both have Kimi's quirk at the same time.

Kin was back on her way, happy to be rid of constant jinxes, in under 30 minutes, and without more than a handjob.

Three hours after that, Izuku was waiting in another room as Aizawa discussed her evaluation with the psychiatrist.

The door opened, and Aizawa entered, to find Izuku looking expectantly at him. Aizawa stared back for a moment...then sighed. "Here's what's going to happen..." He pauses. "...but I want to be clear that you did NOT earn this, you were reckless and stupid...but because you won the lottery, if you can fix that flaw, your quirk can potentially help a lot of people...especially with the right teamwork."

He shook his head before fixing another stare at Izuku and handing him a pamphlet. "Anyway..."

Izuku took the pamphlet and looked down at it and read the header in shock. Welcome to Ultra Institute...
