Four weeks passed and Kabuto declared both twins were healthy and had a fifty percent chance at survival. Kakuzu did not know about their kids' chance had been lower and found himself glad he had not been too rough to Hidan. They had hardly anything to do since Hidan grounded Kakuzu to stay by his side twenty-four seven. Sure they had some good nights when the pregnant man found he was not too exhausted for some messing around. Those nights still were not as satisfying as either of them wished since the baby bump made positioning a bit difficult. Itachi and Kisame helped them out eventually.
Hidan would complain about his size which had increased to where he was able to wear Kakuzu's pants. If Kakuzu would suggest training, however, Hidan would go 'psycho-bitch', as Kisame and Sasori called it, on him and say Kakuzu had said he was fat. Then he would lock himself in their room for a few hours or until Kakuzu breaks the door down. Aside from all the household damage, things were plain and uneventful. Now the couple sat on the loveseat, Kakuzu flipping through the mini-mission reports for the bounties he assigned the other members and Hidan sleeping, head rested in the elder's lap and arms wrapped around his stomach.
Once Kakuzu reached the last report from Kisame and Itachi, his eyes widened a bit. Kisame had gone in alone and come back fairly beaten but alive and successful. He made a note to visit them after Hidan wakes up. He would not dare try and wake him early again after nearly losing his last heart the previous attempt. He shivered at the memory and set the papers on the table. He glanced down at Hidan, face blank as he placed a large hand over one of his partner's. He felt a kick and found himself smiling. The smile vanished when the memorable sight of the deceased infant flashed in his head.
'I wonder if our children will get his immortality...' He thought sadly then gently prodded Hidan awake, expecting a rage from that action.
"Hmn?" Hidan blinked a few times then sat up rubbing his eyes as though he could sense the serious atmosphere, "What's wrong, Kuzu? Better have a good fucking excuse for waking me."
"Tell me about Jashin."
Hidan's eyes became impossibly wide and his jaw dropped in complete disbelief. His mouth closed a moment later with Kakuzu's help. Hidan blinked to clear his questions and sat up straighter.
"What do you want to know?"
"... Will our kids be immortal?" Hidan blinked, thinking for a moment before answering.
"No. Not until they convert. Although if both parents are followers he might make the children immortal." Hidan shrugged.
"... I see..." Kakuzu slouched a bit, "What do you do to convert?"
"Ritual." he sounded a bit reluctant to give details.
"What kind?" he prodded.
"You and another have to stab each other in the heart with this sword while a priest says some stuff. One lives, the other dies. The strongest one usually lives." Hidan mumbled, "Are you planning to convert?"
"... It's me or our kids..." Kakuzu sighed.
"There's another ritual I can do but we would need to visit the fucking temple." Hidan huffed as though the idea would be troublesome.
"A safer one?" Kakuzu laughed, hopeful.
"Unfortunately. Also pretty damn embarrassing." He grumbled.
"What do you mean?" Kakuzu asked, curious now.
"We have to... um... well... get married... in a way..." Hidan blushed now.
"... No."
"What?" Hidan's eyes widened, "Why the fuck not? Don't you fucking love me, bastard?"
"Rings and weddings are expensive. No way we'll be able to afford it and the kids." Kakuzu backed up, defensive.
"... What the fuck kind of wedding are you talking about?" Hidan deadpanned.
"What kind of wedding are you talking about?" Kakuzu shot back.
"A simple Jashinist wedding which involves fucking your partner in front of a high priest and at least one witness." He explained.
"... Oh. Then sure. Let's get married..." He smirked; he did not mind having someone watching.
"Oddest proposal in my entire life but this is the only one I'll say 'FUCK YEAH!' to." Hidan laughed, lunging himself at Kakuzu. "Thanks, Kuzu-chan. This means a lot to me; I've always wanted you to fucking convert!"
"Don't remind me." Kakuzu sighed morosely, pulling Hidan into a kiss then pulled away, "Wait... How many men have proposed to you?"
"Aw, is Kuzu-chan jealous?" Hidan said the last word in the most seductive tone he could manage.
"... Of course I am." He gave an uncharacteristic pout before nibbling at Hidan's neck, "Now answer me."
"T-Three including you. The rest were all a bunch of Mary-s and Sue-s." Hidan bit back a moan.
"Hm... And you declined all of them?" Kakuzu's nips started to get lower.
"All but yours..." He placed a hand on his partner's head as it reached the baby bump.
"Good..."
His eyes shut and he moved his head to the side, listening to the creatures in his fiance's stomach. After a moment, Hidan gave his hair an impatient tug and Kakuzu began to pull down Hidan's (formerly Kakuzu's) pants. He was already fairly hard since their last night of fun was roughly five days ago. A moan sounded as Kakuzu wrapped his hand around Hidan's shaft. He leaned back a bit as he felt something wet tap his tip. Kakuzu wasted no time in taking as much of Hidan in him as he could. His threads leaked out the slits on his cheek, tickling Hidan's thighs.
"Mn, more!" He cried, tugging Kakuzu's hair.
He rolled his eyes and pulled off, replacing his mouth with his hand. He leaned over Hidan, pressing their foreheads together until his small partner bit down on his shoulder. This muffled his cry of pleasure from the climax. He unlatched his teeth in order to kiss Kakuzu, loving the attention. He whined when the elder pulled away, taking in the sight of his naked form.
"Stop looking at me, bastard." Hidan pouted, a bit unnerved when his body was so out of shape.
"I would if I could but you're just too hot." He chuckled darkly.
"F-Fuck, you know how fucking corny and gay that sounded?" Hidan panted when he was pulled on top of Kakuzu.
"Newsflash; we're both men... even if you are pregnant." Kakuzu smirked, running his hands along Hidan's sides.
His body shuddered at the gentle touch and crouched over Kakuzu, feeling the tip brush his entrance. Kakuzu helped him down, loving Hidan's moan when he had impaled himself. Kakuzu smirked, letting Hidan start out. Itachi said that Hidan should not be on his back but it would be fine if he was on top. Moans filled the room as their pace increased. After they climaxed, Hidan rolled off, panting next to Kakuzu.
"Guh... Can't believe I have to go to the fucking temple looking like this." He pouted, poking his bump.
"Oh hush. That's really starting to annoy me. I... love... you..." Kakuzu slowed on the last two words, noticing Hidan was already asleep.
"Mn... Kuzu..."
Sorry for the delay and the dull ending. Just finished this and couldn't resist putting it up since everything is going so slow lately...
