~2 Years Earlier~
"Ne, Len! Thinking about Miku again?" Rin smirked.
Len snapped out of his daydream and looked at his sister, his cheeks flushing a light pink color. "Wha-?! N-no!"
"Lies!" His sister laughed. "It's been 3 years since you first told her how you feel, isn't it?"
"Y-yeah…" And it was true. Three years earlier, when he was 9 at the time, he told the love of his life- Miku Hatsune- how he felt. He was actually surprised when she agreed to go out with him. They had been living with Miku since his and Rin's parents had died when they were only 5. And that was when his crush started. He waited 6-long- years and was quite happy he did. His life was perfect the way it was. He missed his parents, but if they hadn't died, he would have never met Miku.
"Have you had sex with her yet?" Rin asked suddenly, snapping Len out of his inner monologue.
"No! We're too young for that!" Len exclaimed, his face turning red at the thought of actually being in bed with Miku.
"Well, she IS 2 years older than you." Rin stated. "I just thought she would have seduced you by now."
"Well, we haven't gone that far."
"Okay, kids! You're home!" Meiko stopped the car that she was driving.
"Thank you for taking us to the amusement park! We had a lot of fun!" Len said happily as he got out of the car.
"Yeah! Thanks, Aunt Meiko!" Rin smiled and got out as well.
"Hey! Don't call me aunt! It makes me sound old…" Meiko said.
Len and Rin laughed, "Okay! Bye!" They said in unison. They watched Meiko drive away, and only when they saw her car completely out of sight did they go in the house.
Len ran upstairs to look for Miku so he could give her a medium sized panda bear he won for her. "Miku! Miku where ar-!" Len suddenly stopped and heard sounds coming from his room. "What the…?" Len pressed his ear against his bedroom door and that's when he heard it.
"Oh my god! Deeper!" He heard Miku say. What in the world was he hearing…? "Right there! Harder! Oh, Dell Honne, you're a god!" He heard Miku scream in delight.
Len froze when realization finally hit him. "S-she can't be… She's…" Len opened the door and saw it. He saw Miku sitting on top of another man who- he noticed- looked kind like an older version of himself but with grey hair, red eyes, and a not-so-feminine body. He saw that this guy had his… Manhood… As deep inside Miku as it could possibly go. They hadn't even noticed Len and went right on going until the end.
Miku encouraged the man- who she had mentioned was Dell Honne- to hurry up and climax in her because she couldn't take it any longer. Soon enough, Miku got what she wanted and felt the warm fluid fill her up and she moaned at the feeling.
"M-Miku…" He saw the two naked bodies on his bed- HIS BED- tense up and look at him. "H-How could you…?" Tears were streaming down Len's face as he stared at the two laying before his eyes.
Miku got up and put on one of Len's shirts that was laying on the floor. She then went over and stood in front of Len and smirked. "It was easy."
"W-wha-?" Len was interrupted.
"I only went out with you because I felt SORRY for you." Miku said. "But then, I figured it would be fun to toy with your little fragile heart. So I kept up my little charade for 3 years. Of course, Dell Honne over there knew about everything and decided to let me have my fun. You didn't ACTUALLY think that a girl like me could POSSIBLY have ANY feelings that way towards a boy like you."
At that very moment, Len felt as if Miku had ripped out his heart and shattered it into a million pieces. He ran down the stairs as fast as he could.
"Len?" He heard his sister call from the kitchen. "Len, where are you-LEN!" But he was already out the door and out of sight.
