"Okay, I know how this looks."
Dipper glared down at her and Pacifica finally realized that he was taller than her. He hadn't been last summer.
"Really? Because it looks like you're breaking into our room to fulfill the oath of vengeance you made to Mabel before we left last summer."
Pacifica glanced around the room looking for her escape, but then he crossed his arms and are those veins? Focus, Pacifica .
"You little shit."
"Paz-"
"She deserves it!"
"It was last year! And it was temporary dye!" he argued back, taking a step forward. Pacifica looked him up and down, noticing muscle where he had just been skin and bones last year. A runner's build is what it was called and it looked good on him. She had to blink her thoughts away before answering him.
"It was an oath, Dipper. Those are the rules of the prank war."
Dipper rolled his eyes and it was absolutely insane that that gave her a thrill. She did not seriously have a crush on Dipper Pines, did she?
"Yeah, well, the rules also state that twins land on the same side of the battle lines. So get out."
"C'mon, please? This is my only chance," she begged. The Pines twins' welcome back party was still in full swing downstairs, but once the acquaintances started to leave, Mabel would notice her missing. "What do I have to do?"
"Buy me a private jet," he said dryly (and a little too quickly).
"And enable your monster hunts? Pass."
"Then leave."
"Seven minutes."
That stumped him. His head tilted slightly in confusion and Pacifica's heart thumped in her chest. Traitor.
"Huh?"
"I'll give you seven minutes to do whatever you want to me," she said, smiling a little when his jaw dropped. "If you don't snitch and let me stay."
"Excuse me?"
He gulped embarrassingly loud. Pacifica peeled off her varsity letterman to reveal the party dress underneath. It was simple, knee-length, lilac, spaghetti-strap, and it made him wipe his palms on his cargo shorts.
"Is that a no?" she asked.
He thought about it, eyes raking her up and down with poorly-concealed lust. His hands were out in front of him now like she was one of his monsters. He asked incredulously, "Are you trying to seduce me into letting you prank my sister?"
"Trying? I'm pretty sure I'm succeeding," she said, kicking off her Vans and pulling her hair into a ponytail. "So are we doing this?"
"Are we… Do you mean-"
"Stop playing stupid, Dipper," she said, arms crossing and drawing his attention to her chest. "Yes or no?"
He didn't want to trust her, even though they were friends now and had saved each other's lives countless times. But Pacifica knew that if there was one thing she could always count on, it's that teenage boys are pretty much perpetually horny. Especially the ones about to go to college.
"Yes."
It came out all in one breath and he immediately looked like he wanted to take it back, but she gripped his hands and tugged him to her before he could get cold feet. His hands landed on her hips and the weight of them sent a shiver through her whole body. And, fuck, his hands were big.
"Kiss me then, Pines."
And kiss her he did. Pacifica had no idea what he spent the school year doing, but apparently he had gotten some practice.
Her hands cupped the sides of his neck, warm just like the rest of him. He squeezed her hips like he wanted to shatter them beneath his fingers and she hummed against his lips in approval. Yeah, Dipper could kiss.
When she broke it, he chased her lips before slowly blinking his eyes open. There was only a narrow band of brown left around his pupils and his foggy-eyed gaze was seriously turning her on. Pacifica pulled her phone out of her dress pocket and set the timer.
"Seriously?"
"A deal's a deal."
She pulled him down to kiss her again and let him lick his way into her mouth. She moaned into the kiss when his tongue met hers and she pulled his body flush against hers, draping her arms over his shoulders.
It might have been the timer or just the sheer number of hormones coursing through his body, but suddenly his hands were everywhere like the world would end in the next seven minutes.
"Door," he said before pulling her to the door and shutting it. He pressed her against it and kissed her again fiercely, like he wasn't the wirey nerd that she caught singing Babba while she was on FaceTime with Mabel last Friday.
Her hands curled into his hair. His hand cupped the back of her neck, tilting her head back so he could trail kisses down her throat to the dip where her neck meets her shoulder.
"Shit," Pacifica hissed and she could feel him smile against her collarbone. Her leg curled around his and he hummed against her, mouth flying back to hers to leave another searing kiss.
His hand slid down her side to hike her leg up onto his hip and roll his body into hers. She felt him half-hard in his shorts and tightened her fingers in his hair until she felt a shiver go down his spine.
His hand slid up her thigh, up her dress, and onto the band of her thong.
"Fuck, Paz. Time?"
"Not enough for that," she replied, pulling his mouth back to her neck.
He mumbled against her throat, "Bed?"
"Yeah, okay."
"Alright, hold on."
His other hand pulled her thigh up and locked her ankles behind his waist. Suddenly, she was pinned to the door, being held up by his hands on her ass. He grunted against her neck and shuffled backward until the back of his knees hit the side of his bed. Then they were falling onto the bed, Dipper on his back and Pacifica straddling his hips.
She kissed him and asked, "Maybe those monster hunts are good for something."
"Hey, my investigations are for the good of all mankind."
She rolled her eyes and he smiled dopily up at her before pulling her down to kiss him.
"You look pretty up there," he admitted between kisses.
Her heart hammered in her chest when she replied, "You think I'm pretty?"
"Doesn't everyone?" He punctuated that with a roll of his hips and it left her breathless. He sat up to kiss her jaw while she thought of something to say.
"Fuck, Dipper. When did you get game?"
"LARP in the Park," he shot back, wry as ever. She rolled her eyes again and shoved him back on the bed and kissed him.
His hips bucked up and he made a desperate sound that went straight to her head. His hands were everywhere again, pawing and squeezing like his life depended on it. With every kiss, she was losing herself more and more in him.
Dipper's hands found her hips again in a vice-like grip that he used to drag her over his lap, back and forth, again and again. She sat up, holding herself up with her hands on his chest, and rolled her hips to the rhythm he set. A sound dangerously close to a whimper left Pacifica's mouth.
"That's it, pretty girl," he mumbled under his breath, watching her intently as she writhed above him. Her dress had bunched up around her waist, exposing the thong she had on underneath. "You're so hot."
She moaned and wow, was Dipper good at this or what? Her whole body felt like it was on fire and all her clothes were still on.
"Dipper," she said, for no reason really, but her voice crested and cracked and he groaned low beneath her.
"Does that feel good?" he asked, pressing his clothed dick against her. "C'mon, pretty girl."
Pacifica hummed her ascent, squeezing her eyes shut as she chased her pleasure. Her fingers grabbed fistfuls of his ugly flannel as the pressure started to build. She felt him adjust his legs to plant his feet on the bed and lift his body up against her like a carjack. Pacifica moaned and pitched forward, curling her body and pressing down on him.
"Holy shit, Paz, like that," Dipper said.
And then she came. Trumpets and birds and the whole thing. Oh wait, no. That was the timer. Perfect timing.
She caught her breath on his chest, ignoring the hard-on she felt pressing against her sensitive self. One of his hands came up to stroke her hair as he pressed a kiss to the top of her head. When she finally sat up, his mouth dropped open. With a tentative roll of her hips again, the hand in her ponytail pulled and tilted her face to the attic ceiling.
He bucked up into her, movement becoming more erratic and forceful.
"Fuck, Pacifica, you look like you belong up there," and yeah, the time was up but this had to be the hottest thing to happen to her all year, so she let it slide.
She whimpered, so overstimulated, and said, "Maybe that's because I do."
"Oh, fuck ."
He snapped up and clutched her to him, sitting up and sucking bruises into her neck. He bit down and roared into her shoulder, hips stuttering as he came in his pants. Holy shit.
"That was…" She didn't know what to say, but thankfully he did.
"Hot as hell."
"Yeah," she agreed, smiling as he untangled his fingers from her hair. "Yeah, it was."
He smiled back and her heart throbbed in her chest. She slid out of his lap and grabbed her varsity jacket off the floor, watching as he watched her. He was sweating like a heathen and she wanted to tell him as much when he said, "Totally worth it. Feel free to seduce me anytime."
And it's crazy! It's crazy how turned on she was by this boy she's known forever. It's crazy how much she wanted to do it again.
"Yeah, well, that all depends on how well this prank goes."
With a hand around his wrist, she pulled him up from the bed and to the door that he had pressed her against earlier. When she tried to close it, he stopped it with one of his massive hands. Fuck, she needs to calm down.
"I realize," Dipper said with a self-deprecating kind of smile, "that I'm weak as hell for falling for this. I just want you to know… that I'm aware of that."
She shrugged and said, "Nothing we didn't already know, Pines."
He smiled that dopey smile again and she was seriously considering getting her head checked. Because Dipper Pines was not supposed to make her go this stupid.
"I guess not." He ran his hand down his face and shook out his shoulders before going downstairs to rejoin the party. She waited till he was gone to shake her head and let the massive grin overtake her face.
"Dipper fucking Pines."
