-Flash back: Luffy's side-

Luffy was just coming home from school and wanted to surprise Ace with a meal before Grandpa Graps come's home again. He quickly went to the kitchen to make a sandwich since it was for him to eat. He didn't need to burn the house down the 11th time already. After he made the sandwich he went to his room but suddenly he heard noises coming from Ace's room. He slowly creep over the door and slowly peak in. As soon as he did his large dark brown eyes went wide. Seeing his own older brother having sex with his best friend Nami!
His eyes darken to a very scary color and digged his nails into the wall,bit down on his bottom lip and drew blood. Luffy was highly upset what he seen and he quickly ran to his room and locked the door. He couldn't believe what he seen,he seen Ace behind Nami sweating and...Pushing his hair back in the sexy manner and skin was flush red,and he was talking dirty to Nami. Luffy couldn't believe that he found his older attracted,he himself feeling a bit odd now. He licked his lips and picturing himself to be in Nami's place. He couldn't help himself to be feeling hot,he chew on his index finger in a horny manner. So he quickly ran the bathroom to help 'himself'.

After that he was in horror that he masturbate about Ace fucking or simply saying destroying him in rough sex. He had to calm down,went over to his bed. After an hour of think he came up with an idea of getting Ace for himself and realizing his feelings toward Ace. He chuckle darkly and slowly went to bed.

He went over to Nami's house for the day to get her to think that Ace was a horrible monster that's using her for her body. Saying he probably wanted her to get rid of the baby if she EVER get pregnant and a few others disturbing tales of his brother while crying with real fake tears. And sworn to her that don't tell Ace what he said,she did promise him. Not long until Nami was starting the rumors about Ace and what Luffy told her. Luffy was 'crying' in his hands trying to surpass the laughter.

He went home and see Ace drinking at the table with a trouble look so he quietly went over to comfort him like a brother. Ace enjoys it since he needed a hug very badly after what happened. Luffy fixes Ace something to eat and feed him. Ace didn't see nothing wrong with it.
Everyday for the past month Luffy stalk his brother,getting every little detail of him. He scared off or mostly threatening to keep off his Ace. But he did not scared off Ace's friends since he knew that they was important to Ace so let them live for now.

He slowly creep in his brother room one night. And see Ace sleeping naked with the cover barely covering his groin area. He slowly lift it up and see his big brother very big and thick penis. He couldn't help himself. So he slowly let himself get a 'taste', he couldn't help himself getting horny when he heard his 'beloved' moans in pleasure. He quickly notice Ace starting to stir he hid underneath the bed. Ace groan in loss whatever what made him hot so he went back to sleep not noticing his hard on. Luffy checked on Ace to see if he was sleep. When he was actually was he snuck out the room enjoying the taste in his mouth as he went to sleep.

He couldn't believe that Ace was in love with somebody else in their school. The girl name was Vivi cause she was very beautiful and had an excellent personality. And she accepted to date Ace since she was very interested in Ace as well,she even ignore the rumors that was still floating around about him. Luffy wanted to scream and kill anything. He couldn't believe a girl like her stole Ace's heart right underneath his fingers after all his hard work.. Not after six months of work... He had to think of a plan and he get one...

He dress himself like a burglar and snuck in her house one night. He was wearing a black ski mask and black wool gloves and black jeans,shirt and even shirt. He found her room as he enter it very slowly enter it with a knife with a childish grin,dark clouded eyes of pure hate and disgust. She was a sleep in her night gown. He tied her up and ducked tape her mouth. She woke up with a horror expression and it his smile grin even wider.

"Ne? I can't believe a bitch like you stole my beloved's heart. He could never be with a richly trashy skank like you. But I'm gonna make you even more beautiful then ever before." he said cruelly with a sadistic smile. Her eyes started to tear up wishing somebody to save her sadly nobody did. Since he took out everybody for the night.

He slowly yanking on her hair softly as like he wasn't going to hurt her. She did calm down a bit but not for long as he cut her left cheek to the corner of her mouth as a 'smile' and did to the other cheek as well. He ripped off her night gown angrily and craved a smiley face and 'Ace belong to me with care','I'm skank' all over her body as repeat making sure it wasn't deep. He got up after seeing she already out cold from the lack of blood. He left while whistling and changing his clothes in the woods and burning his black clothes and mask. So nobody will knows and he went home for a nap since everybody was still sleep.

After his nap he see Ace drinking again and crying,his uncle trying to comforting him the best way he can. Luffy agree to take over after making a few phone calls. Ace was begging to god why his life becoming a living hell.

Luffy went over to comfort him like a 'brother'. Beg Ace to stop drinking and help him with his homework,Ace agree very quickly.

Ace helped Luffy with his homework for the rest of the night.

The next day everything came crashing down. When Ace came into Luffy's room and start beating on him and Luffy was defending himself. Gaps and Dragon came in and separated them,In Ace's eyes show he knew about where the rumors came from and what happened to Vivi. Luffy was 'crying' but his eyes show that 'he did it all' towards Ace's eyes. That only made Ace even more angrier and storm out the house.

AN: Hmm I feel it was short for me but this is how it be going down. And we need more Yandere Luffy in the world!.
