Chapter Text
Diluc tried not to make a sound as Kaeya thrust lightly, hitting his sensitive spot. Despite his effort, a meek sound still came out of him while Kaeya shushed him. The baby in his arms stirred a little but continued to nurse from Diluc, blissfully not old enough to know that his parents were doing something dirty while feeding him.
Diluc was sitting on Kaeya's lap, his husband's cock inside of him, his hand playing with Diluc's cocklet while another was rubbing his pregnant belly. Diluc had to focus on holding on to his baby steadily and feeding him, while Kaeya kept thrusting and jostling his body.
Kaeya was impatient, not wanting to wait for Diluc to finish feeding their child. Diluc almost finished feeding their third child when he came home and would soon start feeding their fourth child, so Kaeya didn't even have to wait for that long. Still, Diluc's protest died when Kaeya easily raised Diluc's maternity dress, slid down his underwear, and started fingering him.
Diluc's cock was so hard, despite his belly weighing down Kaeya's hand, it was still easy for the man to tease him. Kaeya's hand easily wrapped around his whole cock, squeezing and pumping him. His thumb played with the sensitive head, nail pressing down, and Diluc bit his lips when he finally came from his cock, his body tightening and in turn squeezing Kaeya's cock hard. Kaeya came inside him, filling his womb with his seed again. Feeling it, Diluc came again, cunt squirting.
"Uh…"
"Yes, come for me," Kaeya whispered into his ear, letting go of his cock, both hands now holding Diluc's belly while he nipped at Diluc's neck. They sat still like that, Kaeya still inside even when he was soft. The baby finally let go of Diluc's nipple, falling asleep. Diluc waited for a while to make sure the baby was fully asleep before he squirmed, trying to get up.
"I need to put him to bed," Diluc said because Kaeya refused to let him go, holding down his body, "Then you can do anything to me."
Kaeya finally let him go, and Diluc stood up, the dress falling to cover his messy groin. His thighs were wet, and being so pregnant, he couldn't close his legs properly, so he couldn't stop Kaeya's cum from leaking out of him despite trying to tightened his vagina, wetting his legs even more. Kaeya just cackled as he waddled out of the room towards the baby's room, where a nanny was waiting. Diluc couldn't help but feel embarrassed as he gave her the baby so she could take care of him. She just smiled, and Diluc went back to his room—he was done serving their children, and now he had to serve his husband.
Kaeya assaulted him with a kiss when he came into the room, passionately kissing him despite the awkward position because of Diluc's mound in between them. Diluc melted into the kiss, wetting and hardening again as he tried to kiss back as much as he could despite Kaeya almost devouring him. They shuffled towards the bed as Kaeya finally eased his kiss to pull up Diluc's dress, rendering him nakes.
Kaeya kissed him on the lips more before he sat down on the bed, hand holding on to Diluc's belly before he kissed the skin several times, admiring it. Diluc was a bit overdue now; he couldn't wait for the labor day to come. Not only for the babies but also for the end of this pregnancy.
He was lucky that Kaeya still found him appealing even after his first pregnancy changed his body. But there were times that Diluc kind of wished that Kaeya found him less appealing so they would have less sex. They were in their fifth year of marriage, but they already had four children, with a fifth and a sixth baby on the way. Diluc had spent the last five years pregnant more than not; he barely remembered how to live without a baby belly, as if his body was permanently like that. His swollen breasts never reduced back to their original size like they should; in fact, they kept getting more swollen since he had to feed several babies.
The babies inside of his womb moved, their movements big enough that Kaeya could see Diluc's belly distorting as they moved. Diluc thought that to other people, that should be bizarre. But Kaeya admired it, hand touching the place they just moved. Just like their siblings, despite being twins, they were big, bigger than normal. Diluc had always carried big healthy babies, and Kaeya kept teasing him that he was born to carry babies instead of a knight.
Diluc glared and sometimes hit him when Kaeya teased him, but part of him felt that it was true, with how easily he got pregnant despite giving birth not too long ago. He always got pregnant again two or three months after the last one. Even if they had protected sex more than unprotected one, it took when they did it without protection.
Kaeya finally stood up again and guided Diluc to bed.
"Lay down on your side," Kaeya ordered, and Diluc obliged. Once Diluc was settled, Kaeya took up the space behind him. His fingers prod between Dilucs legs, slipping towards his cunt. Diluc parted his legs slightly to give his husband access, and Kaeya started to finger him again. His fingers scissored Diluc's inside before they bent and started prodding the sensitive part. Kaeya's thumb played with clit, and Diluc was relieved that now he could make sounds again.
He moaned as Kaeya's fingers endlessly fucked him, screwing his cunt. Diluc came again with a shout. Kaeya pulled out his fingers and started playing with Diluc's half-hard cock again, pumping him. Diluc hadn't recovered fully from his orgasm, so he had no defense and couldn't hold back from cumming again.
Diluc panted, hand holding on to his lower belly as he felt a spasm. Kaeya let go of his cock and kissed his cheek, and Diluc chose this moment to say what he wanted to say.
"I want to take a break."
Kaeya frowned, "From what?"
Diluc turned to face Kaeya and brought his hand to his belly, "This…6 should be enough, right?"
They were lucky that they were rich enough to hire a live-in nanny for each of their children. In fact, ever since they got married, the winery business had been even more successful, expanding to the other nations, and they continued to earn greater profits. Their grapes continued to get better as if they were blessed. Maybe they could buy an even bigger mansion for their children to live in one day.
But still, despite the help from the nannies, Diluc had to take care of their children, too, since he was the only one who could feed them. He wanted to make sure to be involved in their lives as much as he could, and with so many children, it was hard to do. He still took care of business, too, not wanting to burden Elzer with everything. When he was not dead tired, he went to important business meetings himself despite being pregnant. And he made sure that he did a good job as a wife for Kaeya too, tending to the man's needs and requests.
So, sometimes, he was exhausted.
"You want to do the surgery?" Kaeya asked in concern.
"There is a new birth control…it's pills, so I don't have to get any surgery."
Perhaps the best solution was easier—they should have less sex or shouldn't have unprotected sex at all. But Diluc's almost non-stop pregnancies were proof that it was hard because they couldn't hold back.
"Mmh," Kaeya seemed to mull it over before he finally answered, "Well, you can try that."
Diluc was actually surprised by the answer, "Really?"
"Sure," Kaeya said with a shrug, "You have done well. You gave me so much love, so many children."
Diluc smiled brightly and moved to kiss Kaeya despite the heaviness of his body, happy with Kaeya's answer.
"Maybe you should fuck me into labor."
Kaeya squinted at him, "Is that a challenge?"
Diluc thought about it and said, "Sure."
"Then make me hard, Mommy."
Soon Diluc was kneeling on the floor, sucking off Kaeya's cock head like a lollipop before slowly taking it into his mouth as much as possible. Kaeya clutched onto his head while Diluc bobbed his head up and down on the length, feeling it hardening inside of his mouth. Feeling it hitting the back of his mouth, Diluc let go to take a deep breath before taking in Kaeya's whole cock inside of his mouth, fucking his throat with Kaeya's dick.
After several times of deep throating, Kaeya ordered him to stop as he was painfully hard.
In turn, after Diluc was on his four and his ass was in the air, Kaeya pressed Diluc on the floor so he could fuck as hard as he could. He made big movements to hit Diluc's inside hard, so hard that anyone passing by their room could hear Diluc's unstifled moans and shouts. The babies inside of his womb trashed around, safe and unhurt but still disturbed by the activity.
Somehow it worked, and Diluc went into labor several hours after they were finally done. Diluc was giddy that he finally had his last pregnancy.

But 6 months later, he shamefully walked out of the cathedral with Kaeya, Barbara's words informing him that he was pregnant again with another set of twins ringing in his ears.
