Kazuichi feels like pushing his luck with Mikan.

“Yeah, it hurts,” Kazuichi croaked. The dry whisper he was speaking in probably did sound like he’d had the wind knocked from him, but the truth of the matter was that he’d already mostly recovered from Hiyoko’s rude strike earlier. Obviously, he had other intentions in bringing up his discomfort to the nurse still perched on his lap.

“Oh, g-gosh! It looked like it did,” Mikan agreed, nodding fervently and wringing her hands together. She put a finger to her lips, locking her gaze onto his crotch with wide eyes that conveyed her interest, if not yet her intent. “I’m so sorry… Let’s diagnose it as we did before. First of all, can you tell me where it hurts?” She moved her eyes to Kazuichi’s own and kept her voice soft, but clinical. “Is it the balls? The shaft? Or both?”

Kazuichi had already seen this similar routine once, so the tension of waiting for the needle to drop on the trigger he assumed he’d activated felt like waiting for the needle to go in for a shot. “Uh… n-not sure.”

Mikan gave him a smile, then reached for the zipper of his jumpsuit. “Sounds like I’ll have to do a thorough diagnosis, then… Would you describe the pain as an ache? A throb? A burning sensation?” As she spoke, she was unzipping his jumpsuit. Her eyes stayed locked on her area of concern, ignoring the stained white tank top she was revealing. “Or are you going to tell me one thing, then change it again? That’s okay, Kazuichi… I’m sure your body is feeling a little funny right now.”

“Ahaha…” Kazuichi laughed, but he wasn’t even able to decide on one of the options. He felt the zipper finally reach the end at the crotch, revealing the colorful boxer shorts he was wearing. He’d forgotten why he'd even worn these back in the original simulation, as they were far from his style now.

Mikan returned his meaningless, nervous laugh with a giggle of her own, which only served to accent how it hadn’t been a proper response to her question. “I see. I see…” Her eyebrows tilted upward slightly as she smoothly slid her hands into the front of the young man’s boxer shorts, which he was making no commendable effort to guard. “How is it? Is it… sensitive?”

“Yeah, I think it’s kyaa!!” The young man made a noise he was very glad he was getting to make a part of this practice run and not his first real experience.

Mikan was poking and prodding around indiscriminately, but retracting her fingertip immediately upon making contact. “That’s not hurting, is it?”

Kazuichi was still bug-eyed, but he shook his head strongly.

“Okay… You just tell me if anything I do hurts.” She kept her eyes on Kazuichi’s face now, wearing a consistent, disarmingly gentle smile. Apparently, she didn’t need to look at what she was doing to know her way around her target. “Does it hurt when I do… this…?”

The mechanic braced himself, but still opened his mouth in a shocked “o” when he felt a hand that wasn’t his own just barely cupping his balls, gently sliding across them as though that hand's owner actually was worried about causing him pain. “N-n-n-nah!”

“Are you sure?” Mikan tilted her head slightly to glance at him from a sideways angle, still smiling. “You seem to be shivering and sweating...”

“I’m g-good!” Kazuichi gave her a shaky grin. “Geez, you’re t-tickling them!” He immediately regretted adding that, resolving that he would never say that if he ended up in this situation again.

For her part, Mikan pursed her lips curiously. “Oh, well… that means... maybe it’s this part?” She slid her cupped hand up from the balls and slowly, softly gripped his shaft, which was already pretty erect from just her teasing to this point. “I don’t know… it seems pretty healthy! Ehehe…~ Does it hurt when I do… this…?” With her pink tongue flitting across her lips, the nurse began jerking her hand up and down his shaft.

Kazuichi didn’t think he’d last a moment of this treatment. “Oh man oh man! M-Mikan hold up, hold up! I’m gonna-“

“Now now, don’t be a baby. The test will be over soon… And I think if something happens, we’ll know you’re well, right?”

“N-n-no, I mean, uh…!” Kazuichi sputtered, unsure of when he’d end up in a situation like this again. Even though he’d already gotten lucky far beyond his regular means here, he wanted to push it as far as he could. “Burning, it’s burning!”

Mikan’s smile twisted upward at the corners, and she licked her lips meaningfully. “Oh? Well, why didn’t you say so? I’ll administer special treatment to the affected area immediately, Kazuichi. Excuse me…”

The nurse couldn’t leave his boner in his shorts for the next part. She fished it out, so that it was poking directly towards her face. She leered down at it, holding her long hair away from her face in preparation.

Kazuichi gulped, breathing heavily. “Y-you know, Mikan, maybe it’s-“

She pressed one of her fingers to his lip. “Hold that thought until I finish, okay? Here I go, ehehe…~” With a cute giggle, the nurse brought her head lower, using both hands to prop herself up on either side of Kazuichi. She stuck her tongue out, and without any further hesitation, began flicking it across the tip of his penis, lapping up precum that had already appeared there.

“Hiyaaah! H-holy…” Kazuichi freaked out even further, throwing his head back. “M-M-Mikan, please!”

She pulled her tongue back in temporarily, showing him a lewd grin. “This is just the preparation, Kazuichi… I’ll start the real operation now, okay? Let me know if this hurts…~” Her grin separated as she opened her jaw, pursed her lips, and brought them down… then began to suck, bouncing her head up and down on his erect pole while supporting herself with her hands on the floor, almost like she was doing pushups. This was beyond even his fantasies… he’d never imagined any woman doing this, never mind his typically timid classmate.

“M-Mikan, get off, I’m gonna…!” Kazuichi’s warning came out in a scratchy yelp.

Her eyes tilted up towards him, briefly curious, before they turned back to the target of her work. She plucked her head off with urgency, but with a satisfied smile as strings of his ejaculation shot through the air, mostly landing in her bangs. “Oopsie! That operation was a bit of a mess… You're feeling good now?”

"Uh..." Kazuichi simply lay backward on the floor, panting, unable to look the simulation of his classmate in the eye, helplessly imagining what his actual classmates would say if they had any idea what he was doing.

“I-I said I made a bit of a mess! It’s all over my hair… I think s-some of it landed on my face, too, Kazuichi!”

The mechanic continued to ignore her, feeling exhausted in every definition of the word. “I can’t believe I literally got jacked off by a computer program… Sheesh…!”

Mikan tried to rise… Somehow, one of her previously steady hands slid out from under her. She collapsed with her cheek alongside Kazuichi’s cum-covered penis, staining herself with even more. “Ah! I’m s-s-so sorry, I got even more of your stuff on my face… Gosh, it's everywhere! M-maybe you should look at it so we can figure out how to clean up?”

Kazuichi had the wind knocked out of him by the collapsing nurse, and suddenly remembered he couldn’t ignore Mikan escalating her attention-getting in a situation like this due to the triggers he’d activated. He finally opened his eyes-

When he opened his eyes, he saw Mikan standing over him, but not the messy face she’d been trying to draw his attention to. Instead, she had her hand near his eye, withdrawing it quickly as he began to open them himself. “O-Oh! Kazuichi, are you awake?”

The young man blearily leaned forward, realizing he was now lying in the Coffin he’d fallen asleep in. “Buh… Mikan? Oh, man…”

The Mikan in front of him frowned, glancing away from him to the other people in the room. He could that she was wearing better-kempt hair in a long ponytail, as well as a long-sleeved shirt beneath a plain white apron and a more formal white skirt. In other words, this was the Mikan of the real world…

She and Hiyoko, who was also in the corner of the room, were staring at the third person besides Kazuichi. The young man with his fists clenched tightly was Hajime Hinata, in his halfway-awakened appearance: one green eye and one red eye locked onto Kazuichi like they were actual targeting radars, befitting the strange target shape of his enhanced pupils. Dressed in a sharp white dress shirt, black tie, and suit pants that were his typical look these days, the mechanic found himself deliriously wondering if the young man had dressed up expecting to meet Chiaki right away.

Hajime put his hands on Kazuichi’s shoulders, looking into his eyes and showing the other man a rare human expression. “Kazuichi. Did you see Chiaki? Was she there?”

Kazuichi still felt disoriented, but he nodded, at least able to understand that question. “Chiaki- The AI, that is- yeah. She is.”

Hajime’s face softened further as he seemed to consider the implications of it. In a flash, however, he was all business again. “How do we get her out?”

Here, Kazuichi’s mind caught up with him. He was fully back in the real world, back in his body. And in the real world, he was aware… “What the- Seriously?! I creamed myself!” Clenching his sharp teeth, the man became aware of the strange, cool sensation around his loins that was thankfully hidden from the view of the others by the plain grey jumpsuit he’d worn when entering the coffin. He tried to put himself back in the correct headspace to answer the question. “Uh… Chiaki is gonna show me how to build something to take her out of the machine. So…”

“So you’ll have to go in again?” Hiyoko finished his sentence. “I think this thing’s too dangerous! You weren’t even responding earlier, we thought-“

“We were wrong,” Hajime interrupted her. “Kazuichi, I'm prepared to call this test a success. You’ll go back in one more time? To get her out of there, with the machine you're going to build here?”

“No!” Kazuichi shouted, to his own surprise. “I mean, yes, but no no, you got it wrong. I can’t just make the machine right now and use it out here. I’m gonna have to go into the Coffin more times. Not just once! I gotta go in a bunch more times. A bunch.”

Hajime looked surprised for less than a second. “How many is a bunch? Why do you have to go inside the simulation to get her out?”

“Uuh… A bunch is ‘I don’t know how many.’” The mechanic averted his eyes from his friend, grinning sheepishly. “And getting her out is… Well, she has an idea of how to do it, but it apparently ain’t the kinda thing she can just tell me. She’s gotta put it in my brain, while I’m in there. So think of it like I’m a computer with a download bar slowly ticking up in percentages.”

The other man paused in thought. “If you say you need more time, you’ll have it. But, Kazuichi… there’s something you’re not telling me.”

“Shit! I forgot this guy is like a biological analysis supercomputer!” Kazuichi thought to himself, hoping the bullets he was sweating were only on the inside. “Uh… Y-yeah, there’s something else. It’s… uh…” Finally, he thought of something that might work. “I’ll tell you, but I wanna tell you privately. Mikan, Hiyoko, do you mind?”

Mikan nodded and hurriedly scampered out, but Hiyoko raised an eyebrow. “What’ve you got to tell Hajime that you can’t tell the rest of us?”

Hajime looked back over his shoulder. “Please, Hiyoko. We owe him some privacy, if that’s what Kazuichi wants.”

Once Hiyoko had reluctantly left, Kazuichi finally faced Hajime with his awkward grin, flushing. “Look, something I didn’t account for. While I was in there, there was a little accident, uh… That is…”

Hajime continued to watch him without laughter.

Kazuichi tried to imagine how he was going to explain he accidentally, somehow, certainly through no fault of his own, ended up with their classmate talking dirty to him and even sucking him off. That’d be a huge pain to go through, and it'd be humiliating. It was so bad, in fact, that Kazuichi began to wonder… “Could I just not tell him? I mean, I’m gonna get Chiaki out for him… Does everybody need to know exactly what I’m up to in there?”

With that, the mechanic cleared his dry throat, then tried out a lie on the man who had once been Hope’s Peak Academy’s genetically-engineered Ultimate Hope. “Uh… I lost control of myself in there. What I mean is, I uh… voided myself. You get it? Like an unexpected body reaction.”

Even Hajime seemed a bit embarrassed to hear that, releasing Kazuichi’s shoulders and taking a few steps backward. “Ah… I think I can help make that part easier for you, if you want. I’ll tell the others you need privacy when coming out of the Coffin. But, Kazuichi… Losing control of your bodily functions is serious. I need you to check in with Mikan later and get yourself checked out. And, for the next few times out, I want you to have her take a look.”

Kazuichi nodded, feeling anxious to get out of the room. He attributed the feeling to the drying mess in his shorts. “I’ll go ahead and beat it, okay?”

Hajime got out of his way to let him leave, but shouted back to him. “Kazuichi, thank you! You can’t know how much this means to us… To me. Can we talk about her-“ The rarely-surprised young man found himself talking to the swinging door as the mechanic rushed out.

The events of the day after leaving that lab felt less and less important to Kazuichi. For whatever reason, his hands itched to work on a machine… Maybe it was his guilty mind’s way of wanting to put what had just happened in the Coffin behind him?

Jabberwock Island seemed somehow drab to him, something he didn’t need to focus on when the world inside the Coffin- or, rather, his very important work, he reminded himself- waited for him.

Without focus, he went to his room and changed his clothes. He visited Mikan; there were no sexual escapades, no lewd glances, not even any entertaining accidents, just an ordinary medical checkup that confirmed there was nothing wrong with his vitals. He ate dinner. He probably talked to some of his classmates again, but he was going through the motions- he was sure he didn’t say anything of note. Definitely not anything that would tip anyone off to his adventures earlier that day.

Then, he went to his room and worked on a machine. In fact, it was the machine that Chiaki had begun to show him how to make. He worked and worked, like a man in a trance.

Then, he went to sleep.
