When Dipper wandered out of the forest completely naked at around 7:30 in the morning Bill was already awake and waiting for him on the porch with a change of clothes, his trucker hat, and a mug of coffee. Dipper offered him a tired smile and Bill wiggled his eyebrows, snapping his fingers so the underwear in the pile of clothes was on Dipper. Dipper, face red, chuckled sheepishly

"Thank you." he muttered, grabbing the pants off the pile and quickly pulling them on. It took him a moment to realize Bill had chosen him skinny-jeans. He raised a brow "Skinny jeans?"

"They look good on you." he commented offhandedly as Dipper reached for his shirt "Though they'd look better around your ankles."

Dipper let out a screech and dropped the shirt he was holding, instantly turning red and scrambling to pick it up

"B-Bill!" he cried in alarm, quickly yanking the shirt on

Bill smirked and stood, approaching the teenager, whom instantly backed away. His back hit a wall and Bill's hands came up on either side of him to trap him there, leaning close to the teen. Dipper's face was glowing red and Bill's smirk widened

"What's the matter, Pine Tree? Demon got your tongue?" Dipper stared blankly and Bill chuckled

"N-No!" he stuttered nervously

"You're right." he mused "Not yet, anyways."

Dipper was unable to respond, as Bill captured the teenagers lips in a kiss. Dipper instantly melted into the demons warm embrace, hands lifting to pull him closer, one tangling in his hair the other resting on the back of his neck. When they parted, Dipper's face was redder than before

"Bill..." he began "Can we..." he trailed off

"Can we what, Pine Tree?" he asked, raising a brow

"I want you to-" he broke off, heart pounding nervously in his chest

"Yes?" he breathed, amusement in his voice, and Dipper knew the demon knew what he was trying to ask for. He also knew he was going to make him say it.

"I want you to-" he tried again, but was cut off by Mabel opening the door

"Hey what are you guys-" she broke off when she noticed their position and smirked, wiggling her eyebrows "Oh ho ho, did I interrupt something?"

Dipper turned red

"Yes." Bill replied

"Wha- No!" he practically screeched, planting his hands on Bill's chest and shoving. "Mabel, I need to talk to you!"

Fear flashed quickly through her eyes and Dipper stiffened, pain stabbing through his chest at the look. She glanced at Bill, and he nodded his head, encouraging her that Dipper was in fact okay, and she was safe. Without another second of hesitation she bolted over and wrapped her arms around him. Dipper relaxed in her arms and felt tears welling up as he wrapped his arms around her in return, pushing his face into her shoulder.

"I'm so sorry Mabel." he squeaked "I- I should've been able to stop myself- I-" he faltered, and she held him tighter

In that moment, Dipper felt safe from the world. Wrapped in his sisters embrace he felt himself relax, her mere presence reassuring him that everything was okay, and she forgave him. She forgave him, and still loves him, and everything would be okay. His hands fisted into her sweater and he pulled her closer, and she tightened her grip in return, nuzzling her cheek against his head

"I forgive you." she whispered "It's okay. I love you, brobro"

"I love you too, Mabes"

BILLDIP

"Hey, Dip, me and Paz are going shopping later, do you guys want to come?"

Dipper hesitated for a brief moment

"What kind of shopping? This isn't the 'here carry my 500 bags of clothing' shopping, is it?" She shook her head, and he couldn't help but doubt her. Nonetheless he rolled his eyes, offered a smile, and nodded "Yeah, okay."

Her smile brightened and she clapped her hands together before turning and rushing out of the room to call Pacifica and let her know the boys would be joining in. With a sigh Dipper stood and made his way up the stairs to his bedroom, deciding he should probably shower before seeing Pacifica, lest she lecture him about personal hygiene for the millionth time. Bill followed behind him, flopping onto the bed while Dipper grabbed a towel. He turned to leave the room, and Bill chuckled, something in his tone sending shivers down Dipper's spine when he spoke

"I'll see you shortly, Pine Tree." he whispered

Dipper didn't reply and made his way quickly down the stairs and into the bathroom, locking the door behind him and quickly stripping off his clothes. He turned on the water and as soon as it was warm he stepped in, sighing happily as the warm water cascaded over his body. His back arched slightly into the water and sighed happily, mind free to wander as he relaxed under the wave of warm water pounding down on him from the shower head.

And wander it did.

Within seconds his thoughts had drifted to Bill, and he bit down on his lip slightly, breath hitching as his mind wandered unbidden, depicting graphic images of the demon, imagining the faces he made when he-

Dipper almost screamed when he felt someone touch him, but the hand that instantly covered his mouth stopped it. His gaze locked with Bill's and his face turned red, resulting in the demon snickering at him. The hand dropped, and Dipper tried to scramble away only to find that Bill was holding him in place

"Bill what are you-" he broke off when Bill looked down and his smirk widened before he glanced back up, gazes locking

"I knew you'd miss me Pine Tree, but I didn't think you'd miss me that much." he whispered "I think it's kind of fitting, though. A Pine Tree and his wood." Dipper could feel the demons smirk against his skin

Dipper almost screeched, stopping himself only when he remembered his uncle was still home, and if he started screeching it would alert the older man that Bill was in the shower with him, and if Stanford knew they would both get killed.

"I hate you." he hissed instead

Bill put on a mock hurt expression

"Maybe I won't help you then."

"Help me? What-?" he broke off when Bill dropped to his knees in front of him, and his blush got ten shades darker "B-Bill what-"

"Shh, Pine Tree." he mumbled before leaning forward and taking Dipper into his mouth

Dipper grit his teeth, hands reaching down to tangle into the blondes hair, a gasp escaping him, and he shivered, arching his back as Bill eagerly began bobbing his head. Dipper hissed and choked on a gasp

"Bill-." he breathed, gaze locking on the demons head as he moved, hands slipping to his hips to hold him in place. He groaned again "Shit-." He felt Bill chuckle around him, and his hips jerked forward, a gasp tearing its way free. "Shit- Bill- Not in the shower!" he cried out

Bill pulled back and raised a brow, smirking up at the brunette, look on his face so casual Dipper almost didn't believe he'd had a dick in his mouth a second ago.

"Where, then?" he whispered

"Take me to bed." he breathed, unable to stop what was happening even if he wanted to, hormones screaming at him that he desperately needed Bill right this second. And he couldn't bring himself to complain.

Bill's smirk widened and he snapped his fingers, and Dipper's back was suddenly hitting the mattress. Another snap, and he knew the demon had turned off the water. Their lips were together almost instantly and Bill nestled himself between the teenagers legs, and Dipper's legs wrapped around his waist securely. Their tongues were involved only moments later, and Dipper bucked his hips upward, gasping when he felt Bill's erection bump his own, heart skipping a beat.

"Pants." he breathed "Off."

Bill sat back up and smirked

"Take them off for me, Pine Tree." he whispered

Dipper pushed him back up and Bill allowed it, and Dipper's hands instantly reached for the belt buckle, undoing it and pushing the pants down Bill's waist. The demon pushed the teen back down onto the bed, kicking his pants off his legs the rest of the way as their lips met once more. He snapped and every last bit of clothing on his body was gone, leaving him just as naked as Dipper. He sat back and pulled Dipper into his lap, and Dipper gasped as their erections brushed together, head tilting back.

Bill's lips latched onto his neck, and Dipper grabbed one of his hands, guiding it to their lengths. They each wrapped a hand around them both, hands overlapping each other's, and began pumping, Bill leading Dipper into a quick rhythm, leaving the teenager a whimpering mess in his lap. His hips tried to buck into their hands, and Bill groaned weakly against his neck.

"Ah- Dipper-" he breathed, and Dipper was embarrassed by the noise that escaped his throat in response to the demon moaning his name.

"Bill.." he begged weakly, bowing his head so their foreheads touched, gazes locking.

Bill's face was a light red, and Dipper bit down on his lip. A moment later, their lips locked together. Dipper rocked his hips into their hands, trying to meet their frantic movements, and his moans grew in volume when Bill caught on and began doing the same, and their lips parted, ragged gasps and moans escaping the demon on repeat. Dipper was almost unable to speak, the only things escaping his mouth ragged moans and gasps, Bill's name escaping on repeat, breathed like it was a prayer and screamed like it was a gift.

"Bill-!" he cried, back arching, their chests bumping together, "Bill- I'm almost there-" his cry choked off when Bill's grip on their lengths tightened

"Me too, Pine Tree!" he bit down firmly on his lip, unable to control his own movements as his hips bucked desperately into their hands.

"Bill- Bill- Bill!" he cried out the demons names at the top of his lungs as he finally fell off the edge and released on their chests, Bill following him almost instantly with a ragged cry of Dipper's name.

The brunette collapsed against Bill's chest, raggedly panting to catch his breath, and Bill chuckled weakly

"We should do that again sometime." he commented

Dipper snickered

"Yeah." he agreed "We should."

"Well." A voice came from the doorway, and Dipper lurched upwards, gaze shooting to the door, face turning red in embarrassment "What have we here?" Mabel smirked

Dipper grabbed the blanket and covered them instantly, and Mabel giggled, covering her mouth with her hands.

"Mabel what are you doing!? Get out!" he cried, voice cracking

"Since you two are done... Sword fighting... We're ready to go." she turned and skipped away, and Bill let out a howl of laughter when he realized she had made a filthy joke, while Dipper made a horrified and embarrassed noise and hid his face in Bill's chest.
