#bkdkhalloweek2022

Izuku was just curious. He saw something in the dark alley that caught his attention and now he seemed to have jumped into a black hole where he was surrounded by a bunch of..."Kacchan?!"

Izuku was at a loss of words of all these ashen blond hair and red eye...monsters.

They all looked like Izuku's childhood friend but they were more...monstrous.

Some of them have tentacles, others were scaley, and others were just monstrous and large with horns and spikes.

Izuku had no idea what they were all doing but they looked at the young middle schooler as if he wasa piece of meat.

It was a similar look as to what his Katsuki looked at him with. These guys were just larger, and bulkier.

Izuku shrieked as tentacles grabbed him, tying up his-

Wrists and legs. Another beastly Katsuki used his claws to tear away all of Izuku's clothes to ribbons.

A certain monster with a long snout and tongue immediately licked up Izuku's exposed pussy, teasing his clit and hole.

Izuku began to cry and sob but he wasn't against-

This.

He's always dreamed about those eyes on him, looking at him as if he was something special and that was what these Kacchan's were doing.

Izuku felt something large touch his face, squeezing his cheek as his eyes were shut tight. When he looked, there was a large, darkened

Tip of a cock right in his face.

All the monsters growled as the tentacles moved to widen Izuku's stance. Both his hands were stretched out wide and some other clocks slipped into it. Izuku could barely wrap his fingers around the shafts. But he shuddered at the feeling.

One was ribbed and thick and the other was girthy and veiny. He just started moving his hands and cried when the monsters all let out a deep growl.

The other cock slipped into his mouth and all his possible holes were being used up by a tongue or cock. He tried to scream when-

Another tongue slipped into his rear but his mouth was just full of cock.

Izuku gagged and choked, drool slipped down his chin and his eyes rolled back to his head as he was now taking in a bunch of large cocks in his pussy, asshole, and mouth.

It was pure bliss. His mind only-

Supplied him with the thought that Kacchan wants him. Desite not it being /his/ Kacchan, these Kacchan's wanted him.

They filled every possible hole and fucked him. He was dripping slick all over with a mix of saliva from the monster's tongue. They all kept going-

Until they stuffed him full of their cum. The others all covered his naked body and face in it and Izuku was just showered in the white seed.

All the monsters growled as they let him go and Izuku passed out, his body twitching and sensitive.

When he woke up again, Izuku was-

Back in the dark alley, his clothes put on as if it was all a dream. But the dripping cum coming out of his holes was a reminder.

What he didn't know was the marks left by the monsters as they all took the time to leave a mark on Izuku's body.

The next day, Izuku was cornered-

By his Katsuki who saw his exposed neck and he glared.

"Who the fuck touched you?!" He growled.

Izuku's eyes widened as he looked at an old mirror in the supply closet and saw the marks on his neck.

It was the monsters' marks, large and possessive.

"Answer me, Deku!"

Izuku trembled, unable to respond. He was confused, thinking that it was all a dream that he might have conjured up.

All those red eyes looking at him.

He was pulled back by a tight squeeze on his collar.

"Dekuuuu," Katsuki growled.

"M-Monster...Kacchan..." Izuku-

Whimpered.

Red eyes widened and he let out a breathless laugh.

"Are you fucking with me, nerd?" He laughed. "Monsters?" He dropped Izuku who fell to the ground on his ass, "What monster would claim you? What's mine?"

"K-Kacchan..." Izuku responded.

"Don't fuck with me, you-

Whore," Katsuki spat and Izuku shuddered when he looked up at those flaming orbs.

"It was all Kacchan," Izuku said, swallowing thickly. He tightened his thighs as he felt slick dribble out of his cunt.

Katsuki's brows furrowed before rising in realization.

"What the actual-

Fuck, Deku?" Katsuki growled.

Izuku looked away, feeling only shame at how much he enjoyed it and currently likes the attention he was being given by Katsuki.

"Did it make you come? Like I would?" Katsuki asked after a moment of silence.

"Not just one," Izuku felt his face-

Heat up as he said that.

There was a long pause where Izuku refused to look up before his chin was gripped and he was forced to look at that heated red gaze.

"Looks like I'll have to do an even better job than them," Katsuki licked his lips.

Izuku's eyes widened as he saw that

Same gaze as what the monsters gave him.

Heated, possessive, passionate.

"Kacchan..." Izuku whined.

And that is how Katsuki found out that Izuku is a freak in bed but loves what Katsuki gives him.
