I hope you enjoy, I don't own Sonic the Hedgehog. Here's chapter 7.

"Chapter Seven:
A Dark Secret."

Second week of the second marking period, and it's toward the end of Monday. Knuckles is on his way home, and Rouge runs up to him. "Hey." She said.

"Oh, hey, Rouge. Why are you walking with me, don't you take the bus home?" Knuckles asked.

"Yeah, but I needed to talk to you." She answered.

"About what?" Knuckles asked with a raise of an eyebrow.

"Do you do well in physics?" She asked.

"Yeah,... my dad makes study on that harder than any other subject. Why?" He asked.

"Well, I need some help in it,... I don't do very well." Rouge said. They stopped walking. Knuckles looked at her with the same eyebrow up.

"So, what, you want me to be your tutor in physics?" Knuckles asked.

"Great. I'll be at your place tomorrow. Bye!" She said, running off. Knuckles just sweat dropped.

"Oh, boy. How did I get into this mess?" Knuckles thought. With that, he continued his walk home.

--The Next Day

Rouge said she'd be over at four. Knuckles was at home, trying to make the house look presentable for a guest,... it was a pig sty.

"I don't know why you're doing this Knuckles, it's just going to get messy again." An older boy said. He had short, brown hair, and blue eyes. His skin was white, and he was in very good shape, just like Knuckles. He wore blue jeans, a black t-shirt, and black socks.

"Crease, I already told you, I'm having a guest over." He said.

"I should care, why?" Crease said.

"Two reasons; One: you've never met, and Two: it's a girl that's coming over." Knuckles said.

"You had me at girl." Crease said, beginning to help him. They finally finished. The doorbell rang. "I got it!" Crease yelled to his brother, who was currently in his room. Crease opened the door, where he saw Rouge standing on his doorstep."

"Is Knuckles around?" She asked. Crease nodded.

"Knuckles, your friend's here." Crease yelled. Knuckles came down the steps.

"Hey, Rouge." Knuckles said.

"Hey." She said. Rouge was allowed in, and sat down on a brown sofa. Knuckles sat down next to her, and brought out a physics book.

"Let's get started." Knuckles said. They sat down there for an hour or so, only talking about physics (sorry, not that big on it myself), and doing homework. "You get it?" Knuckles asked.

"Yeah, thanks." Rouge said.

She smiled, and turned towards him. She had placed one hand on the side of Knuckles' head, and got him to look at her. Wait for it. Rouge tilted her head towards him, and kissed him. It was long, and passionate. Crease was watching the whole thing, and Knuckles was plain shocked it was happening, the look on his face was priceless.

When she stopped, Knuckles was blushing darkly, and still had the same expression on his face. He got out of it quickly, because that's when he grabbed her torso, and lunged her right into him. Rouge kissed back, wanting the more pleasure that he was giving. It's a shame, because, only a few minutes later was when something corrupted,... or is it erupted.

"What the heck?!" A tough, male voice yelled. Knuckles had stopped to see two people standing in front of the door. One was a woman, with long brown hair, and hazel eyes, wearing a suit, and high heels. The man also had brown hair, and he had blue eyes. He was also wearing a suit, and he had a red neck tie, and brown loafers on.

"Oh, hey, hehe, Dad." Knuckles said, worriedly.

"Who is this?!" He asked.

"A friend from school, I invited her over today, to..." Of course he was cut off.

"To make out with her, on our sofa." His dad said. "Crease Kicks Intel, where are you?!" He yelled. Crease came out of the kitchen, and into the living room. "Did you know about this?" He asked him.

"Well, Rouge came over here for some tutoring on physics, which, as you already know, is Knuckles' best subject. So, he invited her over to help her, but it was only a minute ago this started, I'm sure he didn't plan on it." Crease answered.

"Why is are you focusing on a girl, when you should be studying?" He yelled at Knuckles. Knuckles got up, with an angry look on his face.

"I was studying! What, I can't stop for a few minutes?!" Knuckles yelled at him.

"It shouldn't matter, I don't want this happening again!" He yelled.

"So what if I like Rouge, what then, Dad?!" He yelled.

"You're my son, you live in this house...!"

"You're not my real dad!" Knuckles yelled. Rouge was shocked.

"That means neither one of them are his real family."She thought. Knuckles took a few deep breaths, and sighed. He turned to Rouge.

"C'mon, Rouge, I'll walk you home." He said. With that, she packed up her things, and left with Knuckles, to go home.

I know this shouldn't be that shocking to you all, but it's what's going on. Plz R&R.
