Mabel opened one eye to survey the room which had now turned into the rainbow and cotton candy world of her once-upon-a-time bubble prison. Oh, this dream again! Everything looked familiar in the landscape- however- puberty brought some predictable changes. A steady diet of romantic comedies and shoujo novels, along will her experiences with Chad, had resulted in the expression of her adult tastes. These she repressed during waking life; often without even realizing it. These tendencies took nothing away from the fluffy, happy feel of the place in her opinion. She looked to her left to view the latest game in her carnival, Kick the Cheater. Various stuffed animals were walking up to play with vigor. "Step right up!" She called, "Thank you Mister Tickles," she said as she took the octopus' ticket.

"Hahaha! You share my taste in comedy I see. I'll give it to you kid, you've got style."

"Huh?" She looked over her shoulder to view the familiar floating triangle. "Bill!" Oh no! She couldn't risk it, not even in her dreams. She closed her eyes and repeated, "No triangles, no triangles, no triangles…" She could often control her mindscape if she visualized. This was no place to be imagining Dipper's taboo shape.

"Woah! Hey, hey, hey!" The voice echoed along with a sound similar to twisting a plastic bottle. Then it was as if the cap popped off. At that, she opened her eyes and saw a tall blonde with an eyepatch. How long were those lashes? Hubbah. His locks peeked out from beneath a smooth black top hat. His dark eye looked at his slim figure, then back at her in raw shock and curiosity.

"Wow, I guess I did have a thing for him if he's looking like that," she grabbed her chin in contemplation and walked around her creation.

Bill gripped her cowl collar, "You've made me hideous!"

"What, because you're not a triangle? Sorry bud, but I can't risk imagining that."

"Why the hell not?"

"Dipper and Ford," she sighed.

"Ah, Pine Tree. I've been watching him grow from a sapling." He grabbed a lock of her hair with a gloved hand, "You on the other hand disappeared like the shooting star you are…" He let it fall back to her chest.

"I got distracted," she pouted.

Bill looked over her shoulder at what once resembled Chad, "By that?" He shivered, "I'll never understand what humans are into."

"Oh, that's right," her voice was wistful, "you weren't so familiar with the sensations of the human body."

"Uh- where are you going with this, Star?"

"Here!" She exclaimed with glee as she cupped his newly appointed manhood.

"Ah!" He cried out in further misunderstanding, gripping her shoulder for support. "What the hell?" He took a step back to survey his traitor body.

"You know pain, but have you tried pleasure?" She gave an enquiring grin.

"Pain is pleasure," He wickedly grinned back.

"Hmm- how about we scratch the pain?" She came closer and let her palm gently shift up and down his package. She must have been good at imagining, because it felt exactly as she would have wanted.

"Not liking it, nope, not at all," he crossed his arms.

"You're hard," she smiled, teasing.

"Gross," he put a gloved hand over his eye. He'd always looked away when humans were getting intimate. Like a kid watching Discovery Channel, he just didn't get it. It looked stupid. Why was every living being all about that?

"Not gross!" She stomped her foot, causing him to peek through his fingers. "I think it's beautiful."

"Beautiful?" He put his hand down. "I've heard magnificent, awe-inspiring, ominous, and god-like, but beautiful?"

She simply nodded her head.

"Okay," he avoided her eager gaze; what he couldn't ignore the increasing pump of the blood throughout this vessel. He'd never had a human body, well, of his own. It was almost as intoxicating as fracturing Pine Tree's hand. "So what now?"

"Well, I can make it go away if you want," she pressed her mounds to his chest. At the sensation, all he could do was nod in acknowledgement before she pressed her plush lips to his. How were they so smooth? He knew the things that people did with their mouths and he had found no use for one himself. But the way this was going-

"That's not helping," he assured her.

"Oh, it will," she smirked.

"You're almost as wicked as I am, Shooting Star," he mused, "You've got some hidden knowledge in that skull of yours- waiting to make a deal."

"Except nobody loses in my arrangement," she raised an eyebrow.

"Come on, how do you have a deal where one party doesn't lose out?"

"Sheesh Bill, maybe that human form will help you work on those empathy skills. I guess you didn't exactly learn them in demon preschool, so I'll give you a pass."

"I've been around, oh, since the dawn of time. So, yeah- I guess you're right."

"Hows about I show you?" She slipped her fingers through his, "Deal?"

"…Deal," he confirmed. "But I'd better make out on this one."

"Nice choice of words, oh ominous one," she smiled as she slunk lower on his body.

He watched with interest as she unbuckled and unzipped his trousers. She pulled him out with ease and he felt relief at the sensation. What an interesting organ, all flushed and taut, there was a bead of something white at the top. Too his surprise, Mabel's tongue rolled over the liquid and around the tip of him.

"Ah!" He gasped at the feeling. It wasn't pain, but it was heady stuff. He was kind of losing his head. How was it that easy? He watched her mischievous eyes looked up at him with pride and he suddenly felt the need to drive it into her face in retribution. Was she just making a fool of him? To his further wonder she responded eagerly to his bucking hips. Come to think of it, it felt natural. With these moves he was coming close to the edge of something, as if he were going to fall off a cliff into a warm and welcoming ocean.

"Hold on champ," Mabel leered as she took her mouth off his cock. He couldn't deny the irritation that he felt as blue orbs of fire started to form outside of his fingers. "Now, now, I won't leave you with blue balls. Get it?" She snickered, "Blue balls."

"I don't." Bill said flatly.

"Yeah, yeah. You wouldn't. Don't worry, I'm just getting more comfortable," She slipped her slim arms through the long sweater holes, tugging it gently over her head and exposing her pert, bra-less chest.

Oh! Bill automatically closed his eye, but his member responded eagerly.

"Take it all in, William," she urged, "I want you to remember what it means to be human."

He blinked again, and grew to admire the form, the narrow of her waist contrasted to the fullness of her hips. She had grown up without his watchful eye and, well, he felt jealous. Gone were the braces and the square shape. Now she was like two triangles put together, an hourglass; he liked that. The circles were appealing too…

"Touch it," she instructed.

"Only because I want to," he followed suit.

"Without the gloves, bud."

He used his teeth to bite at the end of the black fabric, pulling it slowly from each finger as he noted her savoring the movement. He always like to play to his audience. When he tossed them aside, he felt the air on his fingers. Humans had too many senses!

"Please, touch me," she squirmed.

"Only because you asked so nicely," he smirked as he softly felt the peaks of her.

"Ah!" She moaned.

Shit, was that the sound he made? He hoped he didn't sound like that.

"Harder!" she pleaded as he pinched her nipples.

"So you do like a little pain?" He breathed, "We aren't so different after all, my Shooting Star."

"Shut up," she cooed, "and take off your shirt."

"I don't know…" He asserted

"Please," she implored.

"That's better," he confirmed as he took off the black overcoat and cotton, yellow undershirt. Ugh, he was all peach now. And why did he have nipples too?! He didn't have time to contemplate as the girl pressed herself against him once more. There was nothing like the feel of flesh against flesh. He'd only felt it in mutilation after possession. Yet, this was altogether different at the core of him- as if it ate at the wrath.

He wanted to feel more, "Take off your pants," he instructed.

She quirked her head.

"Please," he bit out.

"Yessir," she beamed, leaping out of her jeans and revealing yellow striped panties that clung to her just right. Why were they sticking between her legs?

"Did you wear those for me?" he inquired.

"Nuh-uh," she blushed, "just a coincidence that sunshine yellow happens to be my fave color."

"Sunshine, huh?" Bill raised an eyebrow.

"Yes," she teased. "Now please take off your pants, it's not polite to leave a girl waiting."

He stepped easily out of what she'd undone already. So this was what it meant when a human said they felt naked. The flesh of him was bare to the wind, vulnerable. He didn't like it. But of course those thoughts went out the window once Mabel was cupping his balls and stroking his shaft so adamantly.

"Lay down with me," she whispered as he noticed the lavish pillow bed that appeared beneath her. He marveled at how she could create. His skills often lay on the other end of the spectrum. The feeling of her hands left him without a quip as he fell onto the down mattress, feathers flying and softly falling around them.

"Um, will you touch me down there?" She bit her lower lip.

"Why so shy?" He quirked.

"It's hard to explain," she gulped, "It's kind of what humans like to keep secret. They don't share with a lot of people. Well, at least not me."

"Oh, but mine's up for grabs?"

"Hey, this is my dream."

"Yes, your majesty," he gave her a toothy grin, observing her wanton expression as he sunk further down her body. He couldn't describe it, but she smelled good. He'd never known such a scent before. Before he knew it, he had his mouth pressed against the mound of her underwear.

"Mm!" she moaned, "take them off, please!"

He obeyed as he was curious himself to what lay underneath. And as he peeled the soaked cotton down her legs, there it was, a perfect chestnut triangle sculpted out of hair. Fuck. He knew then that he had to take her. Even if no one had instructed him what to do, his dick seemed to have a mind of its own- fervently seeking out her slick entrance.

"Wait!" she cried.

"What?" He couldn't hide his annoyance for a being that was used to getting everything he wanted.

"Be gentle," she whispered.

"Don't tell me," his eye opened wide, "this is your first-"

Her lip began to wobble.

"Oh, geez, Shooting Star. I know that this crap is considered special," his heart raced, "I'm not sure how special but…" He kissed her flushed forehead as he'd seen humans do to comfort one another from time to time.

She giggled at the contact, "It's all right. I wanted to lose it this summer anyway…"

"What do I do?" He breathed as his tip remained poised at her entrance. She couldn't help but feel proud of him; maybe he did have some empathy developing after all.

She grabbed him and the back of his head, pulling him in for a passionate kiss. "Do it!" she exhaled, "I'd rather lose it to someone else that has something to lose. At this age it's apparently a rare thing."

"I…" he was afraid to move forward. It was like the blind leading the blind. Everything was on stand still, that was until she flipped him over and pressed herself slowly but firmly onto his cock. That was when his world became constricted to the ridges within her. "Ahmm!" he cried at the sensation.

"Mm, yess!" she hummed as she began to move on him, "I'm glad that didn't hurt like I thought it would!"

"I'd say this is the opposite of hurt," he confirmed as he ground into her. Although he could see the similarities to stabbing someone. It kind of made him hard to think about her enjoying how he repetitively dived into her warm flesh. He could feel the blood pooling beneath it.

"Ah!" she moaned, "There's only one thing left to make our deal work out on both sides."

"Heck, the way this is going, I'll do anything you say!"

"Don't you dare stop until I do."

"Yes M'am," He submitted, "but I'm not sure I'll ever stop."

"Bill," she laughed, "you fiend!"

He held true to his word, although it was becoming hard. So hard in fact that he felt the need to break tradition and use her given name, "Mabel," he huffed, "I can't…"

"Mmm!" She whined as he felt her grow ridged and her spasms swallow him in waves.

"Ohhh," he moaned, "I'm going to take that as the signal you're done because I can't hold… it in… any longer!" He groaned as he felt himself empty inside of her, holding her possessively close as she accepted every last piece of him."

They both lay in the afterglow, regaining their breath. "I hope it's like that in real life," she hummed, "that was perfect."

Bill sat up on his shoulders, his face perplex.

"I appreciate the compliment. But, Mabel…" he spoke.

"Mabel!" she looked at his unmoving, swollen lips. Who was calling her so urgently? "Mabel!"

"Huh?" she opened her bleary eyes, surprised and grateful to see herself fully dressed once more. Oh gross, Dipper, why do I have to see your face right now?!

"Mabel, the scales are off the charts. There was some sort of anomaly," he pointed at a graph she didn't understand. "Bill could manifest himself tonight!"

She sat straight up as she felt her stomach drop and her face drain of color. Maybe she was an idiot after all. "Oh crap…"
