LAST WARNING!

-----------------------

"Fuck, Deku..." nineteen years old Katsuki groaned as he stopped swirling his tongue around his younger brother's nipples. He slowly ran his left hand under the other's boxer, touching his little Deku's cocklet.

"Kacchan!" the fifteen years old boy gasped at the sudden action.

"Jesus, Deku, I missed you." Katsuki whispered as he gave a few licks on his brother's chest before sucking at the pinkish nipples in front of him again.

"Ah! Nhm..." Deku moaned as he jerked his hips up to his Kacchan's hand.

Katsuki smirks before gripping his younger brother's leaking member in his hand, slowly pumping it as the other boy wantonly moans. Izuku's eyes are slowly closing as he bit his plump lips. Upon seeing that, Katsuki pumped the other's little dick faster, finger softly circling on its tip. Izuku tried to stifle a moan as he thrusted his hips onto his brother's hand.

"God. I missed this; I missed you so fucking much. I thought I was going crazy the past four years I'm away." Katsuki whispered on the younger boy's ear after leaving his swollen, bruised nipples. He then kisses his cartilage before nipping it, teasing it. Izuku was panting as he continued his hand's fast pace.

"I-i missed you t-too, Kacchan- hnngg... 'm close..." He moaned and gripped Katsuki's muscular shoulders.

"I know, baby, I know. Fuck. I missed your moans so much. Cum for me, Deku. Cum for Kacchan-nii." then Izuku almost cry as he came on Katsuki's hand.

Izuku missed this too. So much. He missed Kacchan jerking him off while whispering dirty-sweet nothings on his ear until he cum. He missed Kacchan marking him up because he is Kacchan's. He missed Kacchan fucking him hard and rough while he tries (and fail) not to cry or scream from too much pleasure because he might wake up their mother sleeping in the room beside his. He missed Kacchan silencing him with his mouth once he failed to do so himself, kissing him hard and rough, almost like devouring him completely. Swallowing his moans and cries.

God- Izuku missed all of it. He missed his Kacchan.

"K-kacchan, please..." He begs, panting heavily and his face flushed.

"Please what, Deku? Tell your older brother what you need, baby." Kacchan cooed as he took Izuku's boxers off and threw them to the side.

"I need you, Kacchan. Please! I missed you so much, I need you. Please, please fuck me! I'll be good, I'll-" Katsuki cuts him off by kissing him harshly.

He moans and immediately opened his mouth, welcoming Katsuki's tongue. He can feel the older's hand slowly trailing down on his body until it reached his ass and Katsuki's finger is touching the rim of his asshole. He gasped again when the older started to trace the outside of his desperate hole.

Izuku broke away from the kiss, lips bruised and eyes glassy, "P-please, Kacchan... I n-need you, n-now." He begs again.

"Yeah?" the older said then he uses Izuku's cum as a lube, and he slowly slid his finger in.

He watches Izuku's face as he moves his finger in and out. Izuku keeps on moaning as he spread his legs farther, wider. He added another finger, stretching his little Deku's hole.

"I know, Deku. I know. We just need to open you up really good then 'm gonna fuck you 'til you pass out, hm?" He said and the other nodded eagerly, "Good. That's my good boy." He praised causing the younger boy to shiver.

He added a third finger as Izuku's hips started moving, trying to fuck himself on his fingers.

"K-kacchan..." Izuku whimpered, "Mhmm- please..." Slipping his fingers out, Katsuki took off his own underwear and immediately places the tip of his cock on the younger's entrance.

"Ready?" He asked and when Izuku nodded his head, he slammed himself inside of his younger brother. "Fuck..." he groans while Izuku let out a scream of pleasure.

He covers the other's mouth quickly, letting out an amused chuckle.

"Are you trying to announce that we're fucking right now, Deku? Do you want our mother to know? Do you want her to fucking hear us? Want her to fucking know that her two sons are fucking each other?" He asked and Izuku shook beneath him, his hole tightening around his cock.

"Oh?" Kacchan smirks before removing his hand on the younger's mouth, "You fucking want her to know, huh? Hmm... Didn't know you're such a dirty little boy."

He gripped the younger's hips, holding him still before slamming his hips again. He sets a faster and rougher pace that will surely make Izuku scream.

"Scream, you pathetic little whore. Let our mom hear you." He growled as he continued to fuck up into his younger brother.

Izuku tried not to scream. He really tried, but from letting out breathless chants of "ah"s and "Kacchan"s it turned to screaming and crying "yes!" and "more!". He couldn't stop himself. He couldn't especially when Kacchan's making him feel so good. So good...

The older keeps on thrusting faster and harder, hitting Izuku right on his prostate every single time. Katsuki may be away from four years, but he still knew his little Deku's body like the back of his hand.

"Kacchan... Fuck! There! Please, Kaccha- hah! 'm comin- Ah! Yes...!" He cried out and after three more hard thrust from his brother, he was cumming and shooting across his and Katsuki's abdomen. His eyes rolling at the back of his head as he screams like a bitch.

"Hng... Fuck!" Katsuki cursed while gripping Izuku's waist tighter, making sure to leave a bruise- a mark. Fucking his brother ruthlessly, as he chases his own orgasm, "So fucking tight..." He groaned as he cums deep inside of his brother, filling his little brother's hole with his hot, thick cum.

Izuku's little stomach bulging for being so full of his spend making Katsuki so fucking happy and satisfied. He collapses on top of Izuku, tucking his face onto his little brother's neck.

The other didn't protest nor try to make him move, ignoring the heaviness of his oniichan. Instead, he hugs his Kacchan tight.

"Stay," Izuku whispered, voice soft and pleading, "Stay here. Stay inside of me for a little while, Kacchan-nii."

Katsuki kisses his neck before making himself comfortable on top of Izuku, "I will. Anything for my precious baby brother. And I told'ya, I will fuck you till you pass out so be ready."

The younger giggles before closing his green eyes, mumbling, "Hm... Welcome home, Kacchan."

Izuku is happy that his Kacchan is here again. With him. He's so happy that he forgot about how loud he was earlier. He is so, so happy and it's all that matters. They're together again.



Little did he know, they forgot to close the door and it was slightly open. Little did he know, their mother was watching them outside with her wide doe eyes. Little did he know,

Kacchan knew and he let her watch them.
