Giotto grabbed both of Tsuna's wrists together with one hand and took off his belt to tie the wrists together. Tsuna began to kick and scream under Giotto, trying to escape from the blonde, hoping someone would hear and save him. He looked at the body of his friend, Shirou in horror that he as well might end up the same way. Why would Giotto do such a thing to him?! He was so nice. What did he do to deserve this? 'Yamamoto! Gokudera! Help!' He screamed in his thoughts.

As Tsuna began to sob, Giotto had already finished unbuttoning the brunette's shirt and planting butterfly kisses onto his exposed chest. Tsuna couldn't help but react to his brother's touch. Giotto's lips then reached his nipples, licking and biting the pink buds one at a time.

"Ah!" Tsuna then bit his lip and blushes a deep shade of red for making such a dirty sound. Giotto was displeased with him trying to keep quiet and kissed Tsuna on the lips. He pressed hard and then licked the bottom of Tsuna's lip, demanding entry.

Tsuna broke the kiss and shook his head violently. "No!" He struggled with the belt on his wrists and tried to kick him off, which triggered Giotto's anger. He then began to strangle the younger twin's neck tightly with both of his hands until the brunette gave in.

"Don't you dare try to break free from me. You're MINE." He finally released Tsuna's neck and he coughed violently, gasping for air afterwards. Without letting him take another second to gasp for air, Giotto began tearing onto Tsuna's lips with passion, lust, longing, and anger. Tears flowed down Tsuna's face. Giotto seemed to try to ignore the crying, but it hurt his heart to do what he had always wanted to do for a very long time. He had always wanted this—to love and embrace his younger brother and thrust into him in bed in a slow and rough pace and have the both of them moan each other's names. However, Giotto couldn't control himself; now there's no turning back.

Tsuna roughly turned his head to the side to break the kiss and Giotto proceeded to leave trails of kisses down his stomach. Tsuna sobbed and clenched his fists, struggling with the belt again. Due to panicking, Tsuna struggled too roughly that red marks began to form onto his wrists. Giotto grabbed Tsuna's pants, swiftly removed them and tossed them onto the floor near the bed.

"Please stop!" Tsuna exclaimed with tears running down his face. Giotto stroked Tsuna's member with his left hand and used his other to insert a finger into the brunette's entrance. "AAHH! …Ahh!" Humiliation, depression, confusion, and vulnerable were the things that Tsuna was feeling right now. His body shuddered with his brother's touch and his moans grew loud when the blonde twisted his finger inside of him.

Tsuna hid his red face in shame. His eyes were swollen from crying. As he thought that Tsuna's entrance loosened a little, he inserted in a second finger and began to scissor it at the same time as he pumps his member, making him scream in both fear and pleasure. The pre-cum leaking from his member made it easier for Giotto to insert in and out the two digits.

After he felt it was loosened enough, Giotto slid out his fingers, let go of Tsuna's member, and smirked at him. He unbuttoned his shirt and unzipped his pants. Wondering why things have stopped, Tsuna opened his eyes and had his hands over his head. He saw Giotto smirking at him and holding both of his thighs. Tsuna widened his eyes and trembled. He knew what Giotto is going to do by the look of his face. He tried to escape by kicking at him, but Giotto was entirely stronger than him. Giotto spread the brunette's legs and positioned himself in front of his entrance.

"No! Wait! GYAAA!" Tsuna's eyes shut tightly as Giotto succeeded to enter. The pain was unbearable.

Giotto groaned a little and breathed. "….It's…tight…" Giotto smiled at this fact. For so long he protected his younger twin enough to not let some other pervert touch him and take away his innocence, but now, that pervert is himself—but he doesn't mind it if it is himself. He waited for Tsuna to adjust a little before moving. He thrusts into Tsuna slowly and roughly just like how he always envisioned them doing. Tsuna started to feel less pain and more pleasure. "..ahh…ngghh.."

Giotto smiles, "That sounds like a good sound." He grabbed Tsuna's waists with both hands and gently pulled him forward. "I'm trying my best to make it easy and less painful for you."

Tsuna's eyes became cloudy from all of the pleasure he's feeling at the very moment. His skin seemed to burn with every touch and his face was as red as a tomato. Giotto then took one hand and pumped Tsuna's member at the same time with the thrusts. Tsuna moaned and unconsciously grabbed onto Giotto. The blonde smiled widely and felt as if he won everything. "Tsuna, Tsuna, Tsuna…" He repeated with every thrust.

Even Tsuna's mind became cloudy. Giotto proceeded to thrust even deeper into Tsuna until he entered him all the way to the hilt.

"…I'm…all in." Giotto breathed.

Tsuna then felt an explosion of pleasure and saw white, hot flashes. "AAAAHHHHHHH!"

Giotto realized what happened and continued to thrust at that same spot over and over again, making Tsuna scream uncontrollably. He was still pumping Tsuna's member along with the thrusts.

Tsuna tightly grabbed onto Giotto, scratching onto his unbuttoned shirt as if he could tear it to shreds at any moment. Giotto picked up speed and hit Tsuna's prostate, abusing it.

Tsuna then came with a scream, his bodily fluids covered both of their stomachs and Giotto's hand.

In a few more thrusts, Giotto came, spilling his seed inside of the brunette.

"Mine… ALL MINE." Giotto said as he pulled out of him and Tsuna fell fast asleep.

A week has passed and Nana and Iemitsu finally arrive back home after a long trip. Upon entering the house, they found that it was dark and empty.

"Is no one home?" Nana asked.

"It's the weekend. Giotto and Tsuna should be home." Iemitsu stated.

"Giotto! Tsuna!" Nana exclaimed as she walked around the house looking for them with her husband.

Suddenly, a thump was heard upstairs. The two of them walked up the stairs and noticed that Tsuna's light was on. Iemitsu knocked on the door. "Tsuna?"

They slowly opened the door and found a pale, naked, crying, and gagged brunette with both his arms tied on two opposite-sided bedposts. On the other side of the room, there was a large, dry bloodstain as if there was a dead body there before. Nana and Iemitsu widened their eyes in horror and ran over to Tsuna's side.

The both of them didn't know why Tsuna thought that they assumed he was useless, but they acutally loved him very much. They love him that it pains them to see their son in this way.

"We'll get you out of here, okay?" Iemistu tried to loosen the ropes.

"Where's your brother?" Nana asked. Tsuna widened his eyes and shook his head vigorously. He didn't want to hear that name. Not after a whole week of what's happened.

A second later, the door closed shut and locked by none other than Giotto. He held a knife in his hand and walked slowly towards his parents.

"What is the meaning of this, Giotto?!" His father asked.

Giotto had an impassive expression and continued to walk, "It's because you're in the way that we can't be together…"

"We?" Nana shuddered.

Giotto then attacked.

"See? All better." Giotto dropped the knife on the floor and walked over to Tsuna on the bed. The lifeless bodies of his parents lie in the pool of their own blood.

Giotto hugged Tsuna tightly and Tsuna cried. Giotto will dispose of the bodies later just like how he disposed of Shirou's body. He covered his tracks so well that the police couldn't find anything or any evidence.

He kissed Tsuna's cheek tenderly and removed the gag, feeling delighted by his sobbing.

"Now we'll be together forever…and there won't be anything or anyone that can tear us apart."
