Chapter One: A Forbidden Love

"Pacifica Northwest!" Preston's voice was shaking with anger. "You're not to see that boy again. Do you understand?"

Her mother fixed her with a disapproving glare. Of the three of them, she was the only one who's appearance was as refined as they were used to. Pacifica herself wore nothing but a tightly tied robe as she sat in the lavish chair, keeping her eyes on her lap. Her father was dressed properly, but there were sweat-stains here and there. Preston might have been in shape, but the Pines boy was nimble, sixteen, and toned from four summers of monster-hunts and forest adventures. He was too fast for Preston to even grab, let along catch and hurt, even when the kid was fumbling to redo the button on his pants.

Pacifica didn't say, surely they would throw a fit, but she thought her parents might have set this up. Heck, maybe they even wanted this, just so they could have another reason to forbid her from being with him. Her parents were supposed to be on their trip, they weren't supposed to be back for three days from now. Pacifica loved whenever they left during the summer; she'd spend days roaming the woods and hanging out with Dipper and Mable at their house or at the shack.

Dipper and Mabel's parents came up here four years ago, and she was delighted to hear that the family would be staying in Gravity Falls. Mrs. Pines taught English teacher at their school. Apparently, Mr. Pines had a bit of a history with her father, and it wasn't friendly. Thankfully, though, they didn't seem to hold anything against her and seemed fine with her hanging out with their kids. In fact, after witnessing how her own parents treated her, they had agreed that she was welcome at their house whenever she pleased. Pacifica's parents didn't like the Pines's, saying the twins were a bad influence on her, but they were her best friends. No. Mabel was her best friend. Dipper was her boyfriend. They'd begun dating last summer.

They'd had their first – and second – times last night, both together and individually. It had been magical, just the two of them relishing in their love all night. She'd fallen asleep in Dipper's surprisingly strong arms, feeling him stroking her hair and snuggling into his chest. She blushed as she registered a slight soreness in her hips. Dipper seemed to have this way of being gentle and loving, but also give her the time of her life.

They'd been woken up a little less than ten minutes ago by her mother's screaming. As soon as he saw her father's murderous face, Dipper had sprung from the bed and grabbed his underwear and pants. His shirt and hat remained tossed around her bedroom floor along with her clothes. He slipped them on as he outran her father, and raced out of the gates wearing only his pants, which anyone could tell were put on in a hurry.

She could imagine how odd it would look seeing Dipper Pines, who was well-known as the town's local mystery solver and monster exterminator, running shirtless away from the mansion. All that coupled with her father shouting for all to hear at him to stay away from his daughter. It would probably lead to quite a few rumors about them, not that she minded too much. It was common knowledge in the town that the resident mystery solver and the heiress to the Northwest name were dating, and she accepted that there would be no escaping Mabel, who had bloodhound-like instincts for this kind of stuff.

For the first time in years, Pacifica was nervous about what Mr. and Mrs. Pines would think. They accepted her, invited her into her home, allowed her to spend hours with Dipper and Mabel, approved of her dating Dipper, insisted she stay the night after fights with her parents so often the place had become her own little haven. Pacifica had no doubt that they would quickly piece together what happened when their half-naked son hurried into the house, especially if they'd heard her father shouting at him to stay away from her. Oh, the disappointment.

"No."

Her parents eyes widened in outrage. "What?" her father asked, his voice low and dangerous. Pacifica was a rebellious girl, but she'd never outright told them 'no' before.

"No." She repeated, now looking her father in the eyes. "I'll see him if I want to. And I want to."

"No longer." her father declared and her scowl deepened. Her fists clinched in anger. "You will be wed off to a husband of wealth and quality when you come of age. Until then –"

"I love him." Pacifica told him blankly.

"You're sixteen years old, you're not in love." her mother said. Pacifica ignored her.

"How could you possibly love that piece of trash?" her father raised his voice, but not quite yelling. "He's nothing like us."

"Precisely." she returned. "I love him because he's nothing like you. He's brave, honest, selfless, kind –"

"Pacifica Elise Northwest!" her father said firmly. "That boy –"

"Dipper."

"What?" Preston asked.

"Dipper." she repeated and finally stood up in challenge. "His name is Dipper! Why can't you just say his name!?"

"You want me to use his name?" Preston asked furiously. "Alright. Dipper, the boy you are forbidden to see, you are forbidden to see Dipper!"

"You can't do that." Pacifica said, now trying to suppress her tears. Her father had always disapproved on her relationship with Dipper, but the way he just spat his name...

"I just did." Preston smirked.

Now in tears, Pacifica bolt to her room and slammed and locked the door. But she wasn't about just huddle up in her bed and cry. She was still tearing for a bit, though, as she fixed herself up, got dressed, grabbed her backpack and picked up the clothes still strewn about the room. She carefully placed Dipper's abandoned shirt and hat in her backpack, and left her room, re-locking it as she closed the door behind her.

She knew these steps by heart by now. It was far from her first time sneaking out to see the Pines, and she knew what to do. If they found the door locked, the service probably wouldn't go through the trouble of checking on her. Her parents always talked after they'd had an argument, and it was easy to avoid them. From there, she just needed to avoid any servants who might see her, make it to the kitchen and slip into the walk-in pantry. There was a window there that was never locked and opened to the side of the mansion. As for the wall surrounding the mansion, she silently thanked Mabel every time she pulled out her own grappling hook and propelled herself over the wall.

Pacifica took a breath of relief as she landed on the ground on the other side of the wall; her parents wouldn't see her leaving. They'd probably think she's sulking in her room all day. So long as she returned before tomorrow morning. But that didn't matter right now. Her parents, his parents, the rumors, the Mabel. All that mattered was that in a few minutes, she would be in Dipper's arms again.

This is a series of disconnected one-shots and requests are open. However, I don't dabble much in the established AU Falls (RevFalls, MonsterFalls, ect.), so I hope you'll forgive my not being very familiar with them. Oh well, I can try. Also, this is the closest I'll ever be writing to a sexual scene, so if you're looking for lemons, you can turn around right now. Review.
