Katsuki got a heating comforter for his bed.

Izuku was patiently waiting for him to become comfortable before he actually made a move to go get between his legs. 

Katsuki stripped down and laid in the middle of his bed.

Legs open.

Arms out.

"Katsuki you look so beautiful." Izuku murmured as he lovingly dragged his eyes over the blond's scarred body. "My beautiful Katsuki." He walked over to him as pieces of his clothing started to disappear off him, he solidified himself and looked over Katsuki with a smile.

"Come here Izuku," Katsuki called with a purr in his voice. 

He was ready.

Ready to give Izuku everything.

Ready to die by Izuku's way. 

It felt like he was walking in pitch dark and the only source of light was Izuku. He ran towards him and Izuku extended his hand. Katsuki was ready to take it. He didn't want to live in a world without Izuku. It was impossible to even think that.

Izuku came between his parted legs and leaned over to kiss him. Katsuki accepted his tongue and wrapped his arms around him. Katsuki moaned into his mouth as Izuku started to feel his chest, squeezing it and rolling his nipples. Katsuki used his thighs to hold onto Izuku as he grinded their erections together. It was freezing but Katsuki loved it, Izuku bucked back into him as they started a pace. "Haah, Izu-ah~ku. It feels good, love you~" 

Izuku smiled and sucked on his neck  leaving his final bruises to his living body. "Love you too Katsuki, love you so much." He murmured as he tongued his nipples as he rubbed the insides of his lover's thighs brushing his erection ever so slightly. 

"I fingered myself in the bathroom." Katsuki admitted with a glowing face of red. Izuku smirked as he traced the contours of Katsuki as he headed lower and lower. He stopped at the other's erection before swallowing him up in one go. Katsuki flung his head back as he bucked into that icy paradise, his walls were thin so he knew his parents would eventually heard him but he locked the door. 

"Izuku~ I'm gonna come if you do it so good." Katsuki whimpered as he tried to pull away from his mouth, Izuku sucked on his tip for extra teasing before spreading Katsuki's ass for his viewing pleasure. 

"Want Daddy to eat out your little pussy?" Izuku smirked as he featured a new aspect of his death. Body manipulation. He tongue got longer as he opened Katsuki with it. A silent moan came from the other as he laid stiff with arousal. Izuku smirked as he curled his tongue looking for his prostate. 

"DAddy~!" Katsuki suddenly yelled and Izuku concluded that he had found it. "Yes, I want Daddy to fuck my pussy." Izuku chuckled in his head at Katsuki's new found kinks. Izuku was just tossing out what he think the other would go for, turns out his was right.

Izuku retracted his tongue, Katsuki whined and shoved his ass right on his mouth, shivering at the glacial lips pressing kisses to his rim. "Stroke your clit baby, I wanna see you having fun." Katsuki didn't hesitate as he fisted himself trying to calm down before Izuku even pushed it in. Izuku went back to eating him out and somehow their positions changed leading Izuku to having Katsuki ride his face while the other stroked himself. 

Izuku wanted to tell Katsuki his parents could hear him but he left it alone. Where's the fun in that? As Katsuki came his warm walls sucked in Izuku deeper and the greenette decides that it was his turn to get off. He flipped Katsuki on all fours and watched the other grip the pillows in anticipation. Izuku watched that pink puckered hole wink at him, teasing him to get in and wreck it. He pushed inside, Katsuki hissed at the tight entry but he he screamed into his pillows as Izuku buried himself balls deep inside. 

His body started to manipulate until he looked to be around Katsuki's age but with a much wider frame and muscles galore. He hovered over Katsuki, his arms resting on either side of the other's head. "I'm moving Katsuki." He pulled back to his tip before slamming it in all over again. Katsuki screamed as the brutal pacing began. He pushed back to get more of that addictive cock in his ass. He clenched around it, not wanting it to pull away. He wanted to have it in 24/7, he wanted to be a cock warmer.

"Izuku! HArder." Katsuki begged as he parted his legs more to arch his back. Izuku followed along and snapped his hips as he moved a hand to yank at Katsuki's hair. "Uhahh~ More, more." He pleaded as he felt Izuku's cock start to get wider with each thrust, Katsuki could feel his rim starting to hurt from the unheard stretch.

Izuku smirked as he saw Katsuki thrust back onto him with a deep appreciation. He planned to gut him with his cock and make his rim split and bleed. He wanted Katsuki to bleed out from his ass. Before he slit his wrists. He gave his cock more length and a bulge started to appear on his lover's stomach. "Come on baby, you can take more, beg for me."

"Gimmie more, break me with your cock."

Izuku did just that, he pulled out all the way till the tip was left inside then he plunged right back in. Katsuki felt something snap inside him and he screamed in pleasure. His quirk started to go haywire and sparks exploded and burned his bed. He didn't give a damn he bounced on it like his life depended on it. "Izuku! I'm gonna come~" He yelled as he felt a coil winding up.

"Not yet your not bleeding yet." Izuku expanded his girth. It happened, Katsuki started to bleed, he smirked when he saw his cock slowly getting covered in warm blood. "Now that's beauty,"

Katsuki started crying from the unbearable burning in his ass. His erection waned a little but came back full force as Izuku turned his whole body to give a kiss.He cried out as the move made him rip a bit more. He clung to the tongue as he felt himself nearing again. Izuku used his muscular arms and lifted Katsuki and fucked him like a rag doll. He swiveled the boy's hips as he got the other to cling to his neck as he was being fucked into. Izuku felt his essence spilling into Katsuki but he still fucked him as blood pooled onto the sheets. 

"Katsuki come, come now." He demanded with a growl that shook the room. 

"Izuku!" Katsuki squealed as he eyes rolled over, his tongue hung out as he scream, ropes of come squirting everywhere, nitroglycerin secreted from his pores making him feel tingly as he came down from his high. He groaned when Izuku pressed his icy tip against his prostate.

"Not yet." Izuku said with a chilling smirk, he laid the other on his back and began to thrust again as Katsuki clung to his neck squealing like a bitch in heat. The blond's hairless legs were hooked at Izuku's waist  shaking with overstimulation. 

"Too Soon~" Katsuki slurred, he felt light headed and Izuku was all but a blur as he felt another high nearing. He could feel his ass being felt with something, it was as cold as Izu's cock but he didn't mind. He thrusted down back onto Izuku mildly aware he was bleeding heavily at this point. 

Excessive knocking came from the door but they both ignored it. Screams and bangs came but again they ignored it. Izuku and Katsuki were locked in a passionate kiss as Katsuki came dry this time around. "Izuku, Izuku Izuku!" Katsuki chanted like a mantra, Izuku grunted as the last of his essence spilled over into Katsuki.

"That should do it baby, your mine forever." Izuku tongued him as the door nearly broke down from Masaru's efforts. Izuku pulled back and opened Katsuki's bed side drawer. "Come with me baby, let's make love forever." Katsuki nodded his lower half in pain while Izuku pulled out. The cold liquid came splashing out and Izuku smirked at his blush. 

Katsuki took the razor to his wrist and dug in, twisting and dragging until he caught as vein, blood went decorating the wall closest to him. He took the bade to the otherside and did the same as he watched the steady flow color the navy blue carpets. "It hurts Izuku." Katsuki mumbled as he began to see dark spots, Izuku smiled at him and leaned down to kiss him. He weakling kissed back as his eyes slipped closed for a moment they opened but they were heavily lidded. 

"Your coming to me Katsuki." Izuku murmured against his lips. "Don't fight it, come to me."

"Kacchan." He mumbled as his tongue felt heavy. "Call me Kacchan."

"Kacchan, my eternal lover Kacchan." The blond gave a sleepy grin as his eyes closed for the final time. The door broke down and Masaru and Mitsuki witness their son's last moments.

He was smiling at Izuku who had gone back to normal and was holding his ruined hand. Izuku looked over at them with a happy grin, he faded away leaving the parents to call an ambulance which would be proved futile.

Katsuki Bakugo was dead.

Cause of death?

Suicide Rape.
