Chapter Text
The two men giggled, falling onto a comfortable bed. They were currently staying in Aiai, one of the many love hotels littering the town. For a pervert, Hisoka was oddly right about the place is nice to stay at.
Several hotels offered some services, most likely forms of prostitution or love which can be found via the Nen-created NPC.
Killua shifted on the bed, now looking at his partner with a smile “Seems like there’s been a few changes… but a few things seemed to have remained the same.”
“Yup… like idiots assuming all players are noobs.”
“Like the guy’s face when you held him down while I emptied his binder…” Killua let out a small laugh, “Hilarious. He was in utter shock the whole time… too bad he didn’t have the card we were looking for.”
“Yeah, it was still easy to obtain, just a pain to find the spawn location.”
Killua pulled the card out of his binder, “But at least we have it now…”
Hormone Cookies
33 S - 13
These cookies when ingested, temporarily changes the user's gender to the opposite sex. These effects last for 24 hours. The card gives you 10 boxes, with each box containing 20 cookies.
Daniel’s eyes fell onto the card, observing the details and conditions “I still… can’t believe this is something you of all people want to try.”
“Hey, I like when your lips are wrapped around my cock, sucking it for every last drop… but you gotta be the least bit curious about what it is to be with a girl…”
“Nope, I only want to be with…” How exactly did he want to word this? To say with Killua, given that he has NEVER besides that one instance, found anyone else attractive. But if Killua does instead want to try it out… put himself in the position where he’s going to have a female body, he’s not gonna stop him.
His attraction lies in the person he loves, not the body they have “You, if I’m being honest.”
“Right…” Killua blushed, a hand pulling a few strands of hair away from his eyes to tuck it around his ear, “the whole Killua-sexual debacle.”
“You say that now… but it’s my dick that has only been buried to the hilt of your ass.”
“Same could be said about my cock in yours.” Killua held up the card, “Gain, Hormone Cookies. Several boxes appeared falling onto the bed with a gentle thud.” Killua moved nine boxes off the bed, scattering them across the floor without a care in the world, leaving one box only between them.
There were twenty cookies and they highly doubt they were going to go through even a single box on their own. It’ll be fun and games for a bit, maybe one or two cookies for each of them. It depends on whether they wanted to keep going for longer than twenty-four hours.
“The question is who’s going first…?”
As Killua thought about it for a moment, he popped open the box. That was a fair question… who would take the fist dive into sex-changing cookies?
Pulling out one of the cookies, he spotted that they look the same as what the picture was showing on the card. Aura flowed around them, stating the fact that there was a Nen condition attached to every cookie, “Well… I was gonna go first. I was the one who wanted to try this, so I should be the one to bite the bullet first.”
“It does say twenty-four hours… are you sure?”
“Yeah, we already have our safe word. Also, we’ve both stated if we’re going to do this, there are certain limitations on what each of us wants to explore while as the opposite sex.”
When Killua gave a nod, Daniel agreed with the sentiment. He knows they spoke about this briefly, but there was other questions they have failed to bring up. If the card description is to be believed, everything about their body will change.
They would not longer be men… but rather women.
“Do you want to be referred to as a girl during the process, or are you fine not bothering to change the pronouns?” The man was sure he already asked the question, but he wanted to be cautious. Because no matter the changes his partner goes through, he’ll accept Killua for who they are.
Plus, not only did Ashton drill into them, acceptance… Killua will be effectively changing from a male to a female via the cookie. If Killua wants to roleplay as a woman the whole time, he’d be down to try it… but if Killua doesn’t want to do that, even with the body changes, he’ll happily accept still being able to call Killua his man.
“Even though I’ll have tits and a vagina, I’m still a dude on the inside. Like Ashton says, it’s not our body that defines us… but rather our feelings to the core. I’ll always see myself as a man… so don’t bother.”
Killua stopped for a second. There was an although to be stated in the situation “Unless… you want to get into the role play?”
“Well…” Daniel slid onto Killua, moving up his partner’s body to place a kiss on his lips, “You’ll always be mine in my eyes… whether you’re a man or woman. I don’t want to push you into a roleplay position, if you feel uncomfortable with it.”
“Fair… Then I’d rather you continue to refer to me as a man. It’s not that I’m against the idea, I’d just prefer it that way.” Killua popped the cookie in his mouth, chewing on it slowly, “Tastes dry and bland… at least a bit of sugar wouldn’t kill them.” The man groaned a little, coughing a bit of cookie dust in the process. He felt his body shift, contorting, changing via the properties of the Nen conditions.
Daniel rubbed his partner’s body up and down, feeling mounds grow where his chest was. The shirt protruded, lifting it slightly as they grew, showing off a bit of his belly button in the process.
Daniel ran his hands down, ready to feel the thing he loves shrinking, but the moment his hands grasped the spot, there was nothing but a newly formed opening left behind.
Killua panted heavily; his new frame was much different to his usual statue. He felt he was even a little smaller which sucked. At least that means when Daniel takes it, he’s gonna shrink too.
Bringing his hands up, he felt his newly formed pair of breasts, “Damn, I got some nice tiddies… maybe a size 36…B?” Killua played with them a little, savouring the strangeness of the situation.
“You wanna explore your body first?”
“Sure…” Killua sat up, removing his shirt and pants. All that remained was his underwear which had a small wet spot. Possibly from the changes in his lower region. Taking off his underwear, he noticed he was a little wet down there. Maybe that was what it was like to feel a little horny for a woman.
All this was new to him… so he was mostly second-guessing everything.
Killua grabbed one tiddy, giving it a gentle squeeze. He moaned in appreciation, happy to still get a form of arousal, even if he was in a different body. He felt Daniel come up beside him, tongue licking and exploring the nipple of the untouched breast.
Killua’s other hand started to roam, finding the place where his dick and balls should’ve been. Instead, he found a mound with a parting. He brought his finger into the hole, exploring his inner body.
It felt very different to stroking himself off… or even sticking a finger in his butthole. Yet, the familiarity of pleasure still felt the same to him. He let out a soft moan, Daniel moving his hand to join Killua’s, a finger slipping in beside his partner.
Killua groaned at the sensation, removing his finger to taste his so-called pussy juices. It was very different to the taste of cum.
“How do you taste?”
“Different… I wonder if I can transmute my own, taste…”
“Wanna try?”
“Eh… I wanted to explore a little more.”
The man moved his head lower, face being buried between Killua’s newly formed crotch. He gave it an experimental lick. Yup, it tastes different… His eyes flicked up to look at his partner. As Daniel’s tongue slipped inside, Killua groaned. He could feel his boyfriend’s tongue exploring his inner folds.
It was different to getting a blow job but still sensational.
Killua found the man’s hair, tugging and pulling him closer so the tongue could get deeper. Sure, it wasn’t a part of his initial plan, but the sensations felt great, not enough to reconsider his sex in its entirety, but enough to make him want to keep going.
He’s definitely, attracted to only me… Killua moaned loudly “Okay, this proves a theory. You’re not strictly gay… but rather sexually attracted to mainly me.” the tongue slipped out, brushing over the small bump just above the vagina. It was called the clitoris right, the thing that was jokingly considered a myth to other men.
“Alright, fun time is over. You know what I want?”
With a lick of his lips, the man hummed, “Yup. I got the rope…” Daniel got to binding his boyfriend’s arms, making sure he was strung to the bed. It was nothing Killua couldn’t escape from.
In a worst-case scenario, he could always result to using his ability to keep Killua held down unless fun time was over with their keyword. They also have a gesture they could perform just in case. As guys who are often exploring new kinks, they had to find ways to gesture if they’re uncomfortable or not in a situation.
The rule works for the two of them… no matter who was receiving pleasure at the time.
Killua shifted his arms, making sure the bidding wasn’t removed with a simple tug, “You brought the nice bindings… how nice of you.”
“Only the best for my hubby…” Going back down, the man latched onto Killua’s chest, sucking on a nipple as one of his hands explored the other breast. Killua groaned, tugging on the binding in the process. Then his man’s hand had to go down. At first, he thought Daniel was going to finger him.
Instead, he heard an unmistakable crackle of a box being opened. Daniel was going to use protection.
Killua licked his lips in anticipation.
With a quick rip of the packaging, the man rolled the condom onto his dick.
“You better last, if not, let me know, you know I know how to prolong your orgasms.”
“Of course…” Daniel brought his dick close to the entrance… running it up and down the entrance without penetrating it.
“Oh, come on… you, fucken tease.”
“You know the magic words… let’s hear it.”
Killu groaned out of annoyance, “Fine…” The man groaned, holding out his hands so they could get as close as they could to holding his partner’s face. The binding made it impossible to reach, not without breaking the binding or the bed frame. With a smile, he degraded himself, reaching into the horniest part of his mind “Please, fuck my pussy… ravage me till I’m pouring my juices around your thick cock.”
“How does it feel…” The man inched his cock right up against the entrance, “All good on your end?”
“Would feel even better with you inside me.”
Daniel penetrated the man, feeling some of the warmth coating the rubber surrounding his dick. Killua seized up, the abnormal feeling making him shake with arousal, quaking under the pressure of being filled. It was very different to being fucked in the ass.
The man pressed a finger to Killua’s clit, giving it an experimental flick. The insides twitched, squeezing around his manhood like an appreciative hug.
“That feels good…”
“Good…” The man gave an experimental thrust, Killua groaning at the sensation. He felt another thrust, the action forcing him to hold onto the bars. One after another, each thrust drove him closer to that feeling of release.
He wondered how it would feel like, what it’ll be like to be in the throes of a climax while under the Hormonal Cookie’s Nen condition.
He groaned heavily, the finger now completely playing with his clit.
He moaned out of appreciation, feeling the muscle in his body contracting, massaging the tool that managed to get him off. Liquids gushed out, pooling around the hole and length. He panted heavily, whining when he felt Daniel pulling out of him.
Now for the fun part… Killua smiled under his fringe. This was where everything will play out as he expected.
“Why… I wanted you to keep going?” His eyes widened once he saw Daniel’s hand go lower, removing the rubber with a single flick of his wrist. Killua saw the rubber sail through the air, hitting a trashcan with a loud splat, “What are you doing?”
They had already planned for this, knowing it was going to happen. In fact, Killua requested it. The dick was brought to the lower entrance. The man flailed, pretending to struggle against the bindings.
“Don’t you want this…” Daniel breathed sensually, “To feel my bare cock inside of you, blasting load, after load… inside of you.”
Killua shook his head, trying to present it wasn’t what he wanted “You promised you’d use protection… Y-You said you wouldn’t cum inside of me?” Deep down, this was exactly what he wanted. They already planned for how the night ends. But even with perfect plans, there can be mistakes along the way.
Even as Killua was arguing against it, the naked length pressed to his entrance, turned him on. He accidentally lets out a moan, a contradiction during their roleplay.
Daniel brings up his hand, thumbing his partner’s cheek, lips moving closer, “You’re my slutty little whore right… you want it, right?”
“N… No.” Killua threw his head side to side, “I don’t want to be knocked up.”
“You don’t…” The man hummed at his partner’s words, ignoring the constant bucking of Killua’s hips, the way his partner was desperate to slip his length inside himself. But he could feel the constant teasing, and it was doing wonders. He won’t last long… he’ll definitely, need to ask for Killua’s ace if the plan starts to break down.
Still, he needed to play the part designated to him, “How about I test that theory…”
The man edged his dick in, Killua letting out a guttural groan of bliss, words not matching the sounds “No…”
Once he was seated inside, the constant warmth and gripping made him almost nut instantly, ending the night abruptly. Killua rocked his hips, trying to work the shaft penetrating his deepest parts.
Without a rubber, it always felt better for him. He could feel every ridge grip and spread him, giving him pleasure, unlike anything he’s ever experienced. It still wasn’t enough, he wanted more…
“Move…” Killua whispered, desperate for friction. He didn’t want to fuck with his fantasy, not until he got at least one nasty load slung up him. He knows Daniel can go for more, but he’s desperate for a release, even though he had experienced one, moments ago.
Shifting his weight, Daniel buried himself as deep as possible, his partner groaning out of appreciation, a break in their fantasy, but he needed to break it another time. So, he leaned in close, the length barely moving inside of Killua, small ‘paps’ being made on the gentle thrusts as body met body “I’m super close… can you delay me?”
“I can try… although I can’t say I’ll be able to perform it correctly. So, if you nut, pretend you didn’t and keep going.”
“Alright…” Leaning back, Daniel gyrated his hips, now using his full length to rock it inside Killua, “You feel so amazing.”
“You… You too.”
“It’ll feel even better when I fill you up.”
“You promised you wouldn’t cum inside of me…”
“I said I wouldn’t impregnate you, which is different. By now… I think I’m reconsidering that idea. I like the idea of little smol cuter versions of you running around, calling me daddy.” Killua’s frame trembled, “They’ll call you papa. They’d love you as much as I do you…”
The man gave a particularly hard thrust, the hole tightening around him, threatening to milk him for all his worth, “I’ll love them, as much as you love and worship my cock buried deep inside of you. Look at you…”
The man stopped moving, Killua forced to move on his own, rutting against my cock… trying to chase his own, release, “You’re desperate for my cum.”
“No…” Daniel hugged his partner, leaning in closer so Killua could hear the whisper “I’m super close, please stop it.”
Killua focused on his body, discharging a small burst of electricity from within. Daniel felt the static charge, the zap along his cock. He was successfully delayed, but not for long though. Just long enough for him to continue playing out Killua’s fantasy.
“No…” The man mocked once more, “You’re just a horny little slut for my dick.” He started moving again, rutting deeper into his partner, “Come on, beg me for it. Say you want it as much as me too…”
“No, I don’t…”
“You don’t want to spend your life with me?”
“I do…”
“You want me to sling a load up you…”
“I don’t…” Killua trembled, well into the throes of another orgasm. If he can time it just right, they’ll hit it at the same time. The delay was minimal.
“Well, I do…” Daniel heaved heavily, sucking in a breath. He thought he’ll have more than a few minutes. He miscalculated, “I want to have it more than anything.”
Killua shook, with pleasure. He did too… should he break the fantasy, or let it play out? “I’m close… but not inside, I’ll break. I don’t want to enjoy it…” Oh, God… this was such a wonderful idea “I’m… I going to…”
“Then let’s break together!”
“No…” Killua let out a loud moan, releasing once more around his partner. There was a wet gush squirting around the length pushing him over the edge. But he didn’t need to wait any longer. Like a cork popping off a bottle of wine, he felt the gush of cum reaching the deepest part of him, forcing itself to inseminate his temporary womb. So good… so filling…
Daniel hammered away, the constant wet slapping of their hips extending their orgasm. Killua constantly whimpered, uttering ‘no’ until there was nothing more to fill his insides.
When Killua smiled in appreciation, the role play was over.
“So was it good?”
“Yeah, you could’ve acted a little more forceful, maybe utter a few more lines about wishing how much you wished to fill me. Maybe even talk about how desperate I secretly wanted it. Other than that, it was good.”
“I don’t get the idea though… why a forceful impregnation fantasy though?”
“It’s not about being forcefully impregnated. It’s the idea of knowing it could happen, combined with the fact of trying to resist the idea of liking it. I like the idea of you being in a position where you know what I like… you know how much I want it. But I’m playing hard to get, even though I’m matching your movements.”
Killua hummed in appreciation. There was more to it, but his main goal was even though he was pretending he didn’t want to submit, he wanted to feel the sensation of being bred bare. Hell, if he prolonged the use, he could remain impregnated, probably… Although, Pregnancy Stones would be the far better option… because even if he’s a guy, he’ll remain pregnant.
Whereas the moment the Hormone Cookies run out, he doesn’t believe they’ll be pregnant, given he’ll lose the womb in the process.
They’re still young, so they could wait to have kids… but the option was still there “I can’t wait for you to feel this, because it’s great.”
“That’s good…” The man leaned down, offering a small kiss on his partner’s forehead, hands moving to undo the binding. Once the binding was undone, Killua flipped his partner over so he was on his back, “Now round two… but lick me clean, first.”
He pressed the opening to his partner’s mouth, who eagerly stuck his tongue inside, swirling it around.
Killua moaned even louder, unrestrained by his earlier fantasy, “Yeah… that’s it… lick me clean.”
Grabbing his butt cheeks, the man licked as deep as he could, feeling some of his splooge and Killua’s juices leaking into his mouth, down his throat. Killua moaned even louder, curling his body as he felt another orgasm approaching.
There was no warning as cum and juices gushed into his man’s mouth. His boyfriend didn’t complain, eagerly sucking everything up. When Killua pulled back, Daniel licked his mouth clean “I still prefer your cum. It tastes way better.”
“We still have what… twenty-two-ish hours. I can go for a few more rounds.” Killua moved, rocking his hips against the tool which had gotten him off several times already. When he felt the tip enter him, he rocked his hips, appreciating the way his partner moaned, hugging him even closer.
“I’m on top this time. I get to ride you now, so you just lay there…” With a gentle rock, Killua felt it bury inside of him. He wasted no time getting into the swing of things, wanting to experience many more orgasms inside of him.
