Girl meets herself

My brother

Riley's POV
Mom, Dad, go away!" I exclaimed with tears in my eyes, "how could you never tell me I had a twin brother!"
"How do you know we didn't? I don't know if you remember, but you have amnesia," my dad said with a chuckle.
"I would know if he was my brother!" I fought back, "and this is not funny!"
It was an awkward silence until a nurse broke it, "hey Riley, the doctor said you could go home. Hi Cory, Topanga"
"Crap," I thought. I'm already mad at my parents, now I get to live with them.
"Oh hey sis," Cory said. Sis, that's it.
"Hey dad, do you get the same feeling when you kiss your sister as you do with mom?" I asked.
"I have never kissed Morgan!" He yelled quietly.
"Do it now. She is your sister, you have the same blood," I smirked.
"I'm not kissing my sister!" He said.
"I kissed my brother," I said.
Dad and Morgan kissed for like less than a second.
"What did you feel?" I asked.
"Nothing," dad replied, "at all."
"Now kiss mom." I ordered. He didn't hesitate for this one. About 3 minutes later, the make out session was over.
"Fireworks." He said.
"That's how I feel with Lucas, I know he's not my brother." I said.
"Lucas Frair?" Morgan asked, "we had to do a DNA test to contact his parents, they aren't the same as yours."
I holding back tears, I gave my parents a look, "how could you."
"I'll explain," my mom mouthed.
"Riley, I didn't want to do this, but your dad and I watched Lucas force you into the ca-"
"He didn't force me!" I cried.
"As your mother I wanted to protect you. If it wasn't for him, you could still walk, and you'd grow up with a normal life."
"It can still be normal, just a new normal," I said, "let's go home, but first I need to tell a special someone goodbye."
