// NSFW, #luckae, Maayul's Kinktober Day 5: Wayersports, A/B/O, slight inflation/mpreg, pussykae, "sweetpea"

Kaeya keened as Diluc's knot popped inside, sending his orgasm crashing upon him. His pussy throbbed, fluttering around Diluc's cock with each wave of pleasure.

Fuck, it reached so deep inside. Pressed on his organs, warm cum flooding him. Kaeya drooled with his tongue lolled.

Diluc groaned into Kaeya's bared neck as the last of his cum filled him up. Kaeya's pussy milked him of every last drop.

They laid there together, panting and drunk on each other's rut/heat addled scent. The need to breed was sated for a little while now, giving them both a desperate release of rest.

Kaeya sighed contently. He slid a hand over his now swollen belly. "I look like I'm pregnant."

Diluc gave a low purr at that. "That you do. You look amazing," he said, nuzzling deeper into Kaeya's neck.

Now that Diluc had knotted Kaeya, they were in for a while of being connected. It took a while for his knot to go down - usually when it did, they were ready for another--

round.

Heats and ruts were insatiable on their own. Synced like theirs, though... The need was neverending.

"Of course you think so," Kaeya scoffed.

"Should I not?"

Diluc carefully maneuvered them into a more comfortable position. As much as they both loved the mating press, they couldn't stay in it forever. He turned them onto their sides, Kaeya's back to Diluc's front.

There, they were content to rest with what little-ish reprieve they had from violent horniness.

Kaeya relaxed back into Diluc's hold and closed his eyes. Comfy, /loved/, safe and warm, ready to rest...

Diluc's hand on his belly shifted to cradle the underside and Kaeya's eyes shot open.

He had to pee so bad.

Kaeya didn't know how he hadn't noticed his bladder filling the entire time they were fucking - let alone to /this/ extent.

Just Diluc's hand rubbing the underside of his stomach made him clench to hold it in.

He really shouldn't have guzzled all that water beforehand. He had been starving and severely parched after a particularly rough round, and had drank lots of water all in one go.

"Shit," he hissed.

"What's wrong?" Diluc adjusted behind him, causing his cock to shift inside of Kaeya.

A cock that was pressing against all his sensitive spots and his bladder.

Kaeya clenched his legs together. Just that upwards press made him nearly lose control, wrenching a low whimper out of him.

"Stop moving!" Kaeya grabbed Diluc's hand and wrenched it from his stomach. "I need to use the bathroom /right now./"

"You ca--"

"/Right now!/"

Against his better judgement, Kaeya wiggled his hips to pull himself off Diluc's knot. It was too big - his pussy couldn't stretch that far without severely hurting him. Just the sharp bite of stretch made Kaeya gasp and double over--

nails digging into his skin just to /hold it in./

They were stuck together, truly, until it went down.

Kaeya's heart sunk to the deepest parts of his stomach.

He couldn't hold it.

Diluc shifted again, cock pressing further upwards, and Kaeya damn near cried. Kaeya swore Diluc did that on purpose. He could almost feel a little trickle begin-- /almost./

"I'm gonna piss myself," he gasped, "I can't move, you can't either-- please, just get me--"

"Then do it."

Kaeya froze. "No! Not in the bed," he hissed. "And not on you." Tears pricked his eyes. "I can't hold it anymore, Luc, let me--"

"Let it out for me, Kae. You're okay."

Diluc took the same hand Kaeya wrenched off and firmly pressed into Kaeya's abdomen. The poor thing was swollen with more than just cum - Diluc could feel how bloated Kaeya was.

Kaeya cried out and tensed so hard to keep it in. He truly did his best to hold it.

That's what made the warm gush from between his legs as he forcibly relieved himself all the more humiliating.

"There we go," Diluc purred in his ear. He massaged into Kaeya's abdomen with an unrelenting hand. "Let it go, sweetpea. Such a good omega for me..."

Kaeya couldn't stop it no matter how hard he tried. Piss soaked the bed, his thighs, and most humiliatingly, Diluc.

He was fucking pissing on Diluc.

The flow stuttered towards the end, but it never stopped until he was completely empty.

Kaeya hid his face in his hands, tears flowing as quickly as his flow. He babbled incomprehensible apologies.

"Why would you--"

Diluc's cock inside twitched. Realization dawned on him.

"You're fucking turned on by this?!"
