Family "Friend"

I wanna go home

"Are you excited to see my hometown?" Tom said, sliding closer to me in the back of the taxi cab. "Sure." I replied. I'm trying to keep conversation to a minimum. "It's very a very nice school, Bill's sad he couldn't come."
Bill doesn't know what Tom did, And he never will.
"That's nice, Tom." Gosh, can he just stop talking to me? "You know, there's this old park next to the school. Kids go there to...You know..." he put his hand in my thigh, sliding it up and up...
"COOL!" I shoved his hand off of my leg and moved as far as the seatbelt would allow me to.
The cab driver said something in German, to which Tom replied with a "Ja." I want to ask what the driver said but I don't wanna talk to Tom...Oh well.
"Look Maria! We're here! And don't worry, lots of the students speak English. I'm sure you'll have no trouble meeting some nice girls. And guys..." Tom put his hand back on my thigh. Oh I wish I didn't wear a skirt! "Cool." Finally, I see a large building with a bunch of teenagers out front.
Time skip
The dean is a nice lady, probably in her mid 30's. "We're very excited to have you here!" She has a thick German accent. "As for you Tom, I'm sure you can help our new student navigate these halls. I'll be sure your dorms are close!"
Really? Is she being serious? I smile and nod along to what she's saying.
She turns to me.
"Your parents tell me you two are friends?" She asks in a tone that shows how oblivious she really is. I stare at her blankly, I really don't know what to say. Unfortunately, Tom isn't as shy. "Yes, we have been very close for a while now." He looks at me and smiles in a mischievous way. It makes me want to throw up. "Very nice!" The dean says. Just then, a girl who looks about my age (16) walks into her office. "Frau Fischer? Ist der neue Student schon da?" She stops and smiles when she sees me. "Ah, are you the new student?" She ask very politely. I smile back. "Yes, I'm Maria."
"Very pretty name! I'm Lina!" She turns to Tom. "Hey Tom, wie geht es Bill?"
He shakes his head. "Er konnte es nicht schaffen, aber er sagte mir, ich solle Hallo sagen, wenn ich dich sehe." She grinned. "Enough with the interdictions. Maria, this is Lina. She's your roommate. Now, Lina, can you show Maria to the room? As for you Tom, help them get settled." She turns and walks out.
"Let's go Maria. You too, Tom." On the way to the room, Lina and I become friends. She's very funny. Tom follows close behind me, probably staring at my ass. He's such a creep.
"Here it is! Your uniform is on your bed. I have to go, there's a student government meeting. You'll help her, won't you Tom?" She turns on her heel and starts tap-tap-tapping away on her phone. Tom turns to me and grins in a wicked way. "I can unpack by myself." I go to shut the door, but he puts his foot in between the door and the wall before I can. He walks inside my room and locks the door. "Tom? What are you doing?" My palms are sweaty and I'm close to tears. "Nothing." He picks me up and Throws me onto the bed. "Tom stop!" He climbs into my bed and gets on top of me. "No!" He covers my mouth, stopping my screams. "Shhhh" It sounds so evil they way he does it. He lifts my shirt over my head, takes it off, and then throws it on the floor. He starts massaging and playing with my boobs. His dick is hard, I can see it through his baggy pants. Just then, I hear a knock on the door. Tom quickly gets off of me. He throws my shirt to me while l mouthing the words "Don't tell."
As much as I want to, I know I can't. He knows this too. "Sorry! Did you lock the door Maria?" He calls out to who ever is outside my room. "Uh, Tom? Maria? It's me, Lina." A wave of relief crashes over me. I put my shirt back on while Tom goes to unlock the door. He's still staring at me and licking his lips. He turns to Lina as he opens the door. "Sorry. We're just talking." 
"That's okay, I just needed to give Maria her schedule." She hands it to me and says, "we have like 3 classes together!" I smile weakly and take it from her hands. Tom looms over my shoulder in a mysterious way. If he wasn't my rapist it'd be super hot. "Oh look, we have the math and history together. It's nice that they translated it into English for you." He looks at me in such a malicious way.
