The first time Hisoka had enjoyed Illumi’s body, he had not expected a new assassin-in-training to be the product of it. In fact, it wasn’t even an option he considered. Despite Illumi being the oldest of multiple children, Hisoka saw the murderous aura of the Zoldyck family as a form of birth control. The thought of a Zoldyck having a child out of love never crossed his mind, yet here he was. Sure, it was an accident, but he could not deny that the thought of having his own little one brought him joy. And there was nothing that could make him part from Illumi.
Their first time was slow and messy, just like how their missions went because of Hisoka’s need to test and play with the targets.
They tested each other's limits and played on their boundaries, trying to find what made the other tick.
Hisoka had found out that if he thrust deeply into Illumi, allowing the head of his long cock to nearly rub against Illumi’s cervix, and rotate his hips, allowing his shaved pelvis to rub against an erect clit, Illumi went quiet with pleasure. It was a beautiful sight. To watch deep, black eyes widen in a pleasant shock and a thin, milky neck extend as Illumi throws his head back, his wispy hair pooling on the bed as if trying to become a part of the sheets underneath. Hisoka repeated this act often during intercourse, too addicted to this sight of his lover to ever think of stopping. Illumi never reacted as strongly when Hisoka had on a condom, so they went without, testing fate each time they had sex.
Which, of course, led to Hisoka’s current predicament.
They had gone grocery shopping together. It was usually a solo task, as they often split chores to finish everything faster, but with Illumi’s nesting period coming a bit earlier than normal, during his 2nd trimester, it was impossible to go without him. Ilumi had made an extensive list of things to pack their pantry with and baby-safe cleaning supplies to clean the nursery with. Hisoka had pointed out how odd it was for an assassin, who had been trained to tolerate poisons via ingestion, to worry about what was considered safe for a baby. All this earned him was a needle pressed against his throat and, while erotic at times, the odd sensation of feeling Illumi’s bloodlust filling the surrounding space. With the ever growing baby pressing against Illumi’s bladder and causing various other problems, Hisoka told his other head to calm down, knowing he’ll only face disappointment if he pursues his needs.
So Hisoka let Illumi tag along, allowing the assassin to fill their cart with unnecessary non-perishables and various types of name-brand bleaches because Illumi wasn’t entirely sure which brand was best. Hisoka wanted to say all bleach is the same but he kept his mouth shut, not wanting to fight with his pregnant lover in public.
Though it seems like he had no choice in that decision. Hisoka cut through the baking aisle to get to the butcher at the back of the store, when suddenly Illumi pulled the cart to a stop.
"We need at least 10 of these." Illumi points to the shelf.
"...no we dont?" Hisoka says questioningly.
The shelf Illumi had pointed at was full of marshmallows in different forms. The specific form at the end of Illumi’s finger was marshmallow creme in a jar.
"We do need it,the baby requires it."
"Do you plan on feeding the baby marshmallow creme?"
"she will eat it through me. After all, why else would I crave it?"
"Illumi… No, I'm not buying you that."
Silence followed his words, which, despite being common, felt unnerving. And Hisoka's unnerving feeling was validated when he turned around to see Illumi, staring at his feet and dumbfounded by the tears that ran down his cheeks.
Illumi was raging with forgotten hormones. He spent years suppressing them and now they bounce back with a newfound fury, as if angry for being buried. Throughout his pregnancy, he became more emotional, too quick to angry and to cry. He felt helpless against the needs of his body. So, he listened to it, and let it do what it wanted. He could not, and did not try to stop the gentle tears streaming down his face. Those tears quickly turned into sobs.
Hisoka stared wide eyed at his sobbing lover, his brain taking a few seconds to process what was happening before he rushed to Illumi's side to give him a hug, only to be surprised when his arm was pushed away. Illumi wanted one thing and one thing only.
Illumi looks up at Hisoka with the saddest puppy eyes Hisoka has ever seen. Not even Kalluto can pull off that heart-clenching look. Hisoka diverts his eyes so he won't get waived by such a sight.
“Love… I know you want it but I’ll only make you feel sick.”
“NO IT WON’T!” Illumi’s voice booms through the aisle, causing people, even those with their own tantrum-throwing children to peek at them in curiosity. One Parent nods as they let out an exhausted yet happy sigh when they notice Illumi’s round, heavy stomach.
But the curiosity was short-lived as Illumi’s mood became more erratic, causing his aura to fill the entire store, filling each shopper with a sense of dread and fear of what’s to come.
It wasn’t the first time Illumi had an intense craving, but there have been many times Hisoka had successfully talked his lover out of them. Such as the craving for cheap, oddly yellow spray cheese, with his reasoning relying on the fact that Illumi is lactose intolerant. And when there wasn’t an excuse, Hisoka simply put up with the consequences of saying “No” to a pregnant person. Not listening to Illumi’s orders to a T was something he did often, hence why their missions are rarely quick and clean, but it was something he only did if the consequences were tolerable. Not wanting his favorite grocery store to go-under for something as simple as Illumi murdering the owners over marshmallow creme, Hisoka caved in.
He sighed as he began to slowly fill the cart with jars of the creme, only stopping when Illumi’s tears began to subside.
15.
It took 15 jars of marshmallow creme to get Illumi to calm down enough to finish shopping.
And boy did he eat them. Whatever the little one inside of him was doing to his body, it did it to the extremes. He ate the 15 jars and then threw a tantrum until Hisoka went and bought more.
The young boy behind the cash register became worried at seeing Hisoka over and over again, always emptying the shelves of the marshmallow creme the day it got stocked. The young boy would’ve asked, as he did with every interesting customer, but Hisoka’s aura was deadly from sleepless nights filled with his lover's cries and screams. It seems like the slightest thing would push him over the edge. So the young boy did nothing but his job for all 5 times Hisoka came in and emptied that shelf.
To no one’s surprise, months later, Illumi gave birth to a chunky baby girl. And, to Illumi’s dismay, Hisoka nicknamed her “Marshmallow”.
