The room felt so hot, loud moans echoed throughout the halls. Crying and sometimes screaming. The time to please him all over again had come around again. The man was satisfied.

After (y/n) submitted to getting pregnant for Muzan to have someone to take over what he's begun, he hadn't stopped showering her with pleasure and affection. Already confirmed pregnant by 8 weeks, he didn't stop to not cherish her body while it lasts. Though even if she does get bigger, he didn't plan on not giving her any. This was probably the 4th position of the day. A mating press. (Y/n) cried out as his semen gushed from her thighs now, she was stuffed like the first time she remembered. Her drill leaving her lips after Muzan gave her a kiss. The trail connected with his lips after every passionate kiss. His aggressive behavior didn't lighten up even a little. He still seemed overly excited.

Muzan's nails dug into the bed as he thrusted as hard as he could. It sent your nerves on a frenzy and you couldn't control the moans and cries that came out of your mouth. A grin always on his face when he had the chance to look down at you trembling. His god complex just annihilating you into being more submissive. He continued to thrust though her orgasm already twitched along his rough shaft, he wasn't finished. He'd lift himself off  then have you hand off the side of the bed slightly, his hands gripped your sides and held your hips firmly. A pause suddenly but then the motion continued. He threw his hips against your already red ones again. The blood rushing to your head, making you dizzy. He watched as your honest body reacted to this new position. The crazy thing was when he didn't mention when he'd be cunning. He just did so. He probably has the same amount you had. A 'Tch' left his lips this time.

"H-Hah!" A loud pant and he rolled his head back. Working out the last strokes before a low growl left his lips. More thick ropes flooding to stain the bed sheets as well as stick to your skin. He didn't pull out though, possibly debating if he should throw you into another round. You felt so tired nonetheless hungry. He then pulled out and it all just came in a rush. Muzan pulled your body carefully back on the bed and looked at your tired form. He looked unamused but smirked in his thoughts. "If this was to shut you up during your constant chatter.. I would've done this more often." He chuckled and picked you up, sitting you straight. He let go and leaned back against the bed. You watched with tired eyes as his erection flung up. "I've been doing so much. Now why don't you get on your knees." He commanded with his seductive tone.

You obliged. Your tongue graced the tip before locking your lips around his slightly limp shaft. He let out a relaxed sigh before placing his hand on your head. Your slow pace couldn't do. He's been going wild. Your eyes looked up at him cutely which made him blush. The feeling was short for he really has hesitated. He grinned and took a grip of your hair before shoving his length down your throat. "Don't look at me like that! What's with the shyness??" He growled. Your eyes teared up with the sudden action. He held you as you choked slightly before pulling you off. Another long relaxed sigh as he watched your mouth had completely salivated his full erection now.

"Awe~.. don't make the at face... you look so messy." He chuckled while still gripping your hair.

"You're so rough with me..." you whimpered. It was a vein that crawled up from his neck to under his chin. A nerve.

"You don't think I know that?" His voice cold. Muzan had forced your lips around his twitching shaft again. It was throbbing in your mouth like crazy from the warmth. This time he didn't hold you, he started to move your head at a pace he liked. He gave you enough space between the action to breath yet it was short for he was working for an orgasm for himself. "Shit... get used to this, Love~.." he watched as he controlled the way you deepthroated him. He rolled his head back, his hands tangled in your hair. "Fuck." He cursed. It was not until his length was pumping instead of just throbbing. A hiss left his lips and the bittersweet taste flooded your mouth. He pulled you off and the rest spilled onto your lips and face.

"I'm hungry...." You whined. The taste wasn't tasty at all. His face didn't express anything until he smiled.

"Well, we should eat something... I almost forgot you're going to experience some changes."

After months passing, (y/n) discovered she was going to have 3 kids. Muzan smiled to the doctors as they were aware of who he was. This wasn't his first time there. Not just we're they going to triplets, they were all boys. He was ecstatic and it showed throughout the visits. A healthy pregnancy that also revolves around Muzan's lust. He used his spare time to please his wife as a reward for giving him sons at all. Eventually, giving into the list as her body was going through changes. It now becoming where (y/n) would start to blow him under the dinner table even while he ate or worked, Reversed cowgirl on the couch when he watched horror films, or bend over for him while showering together.

Finally the time was up and you were to go into labor. Muzan watched from afar, with a grin on his face. He was pleased to find the woman who was to carry his children into the world. All of her sons were able to be pushed out, but not without the war cry of a woman giving birth to life. Though something did change, he was holding his children after everything. He admitted he didn't want to get his attire dirty from the blood and all, nor get it on his skin during labor.  One at a time, they were cradled in their fathers arms. (Y/n) was awfully tired but happy to look.

As time progressed, (y/n) spent her time with the kids more than Muzan. He only tended to them to teach them something, to build a strong character. It was funny how your sons were so silly like you were that he got so stressed mid talk. "My god. Why're they—"

"They're kids. C'mon. Maybe you should wait a little." You giggled watching Muzan bond with his sons. They still loved him very much even though he could be cold. Though after your recovery. It didn't stop Muzan to nail you when he found out. He came barging in the room.

"Tch. You thought you could hide these papers from me! Oh, now you're asking for it." You had just put the kids to sleep and you were tired. You cried out quietly but Muzan grabbed your ankles and pulled you towards him. "Oh! Fuck no..." he growled and pulled down your bottoms, harshly spanking you.

"N-no~!! Please..." you moaned to next feel his tongue press against your slit. It then forced his ways into your walls. "D-dammit..." you melted into the feeling.

A part of you was feeling instant regret for letting him get ahead of himself. When will you get a break?
