Bite Me

Bill was on him before he even had time to protest. The demon had his mouth pressed firmly against his. He could hear his clothes ripping, but he barely noticed. Bill was just too close, pressing him into the bed…rotating his hips. He tried to fight the blush that was slowly taking over his face, but when he moaned when Bill rocked his hips again, the blush won, taking over his face and chest.

The demon's lips left his and started to trail down his jaw and onto his neck, nipping at the skin. Dipper tried to push at Bill's shoulders, failing miserably. Bill noticed and chuckled in the crook of his neck. "Boy, you can't tell me you don't want this," he mused, palming Dipper through his pants. Already, Dipper was getting harder. "Plus, isn't this what you summoned me for?" he purred, licking the shell of Dipper's ear.

"I-I didn't mean to summon you," Dipper forced out. He tried to shove the demon again, only to have his wrists grabbed by warm, leather covered hands.

Bill leaned back with his hands tightly grasping Dipper's wrists. "Too late for that, Pine Tree. You summoned me and gave me my orders, I just happened to accept them," he said with a smirk. "Lucky for you, I'm not asking anything in return," he taunted as he moved until he was nose to nose with Dipper. "But I will if you keep trying to back out." His eye narrowed as he spoke.

Bill's warning sent shiver of fear down Dipper's body. Hesitantly, he nodded, causing Bill to grin happily. "Good! I'm glad to see you finally understanding, Pine Tree," Bill praised.

Bill gave him a peck on the lips and released his wrists. Dipper could feel the dull ache, knowing his wrists were probably bruised now. He grimaced, wondering what he even got himself into.

"Aw, Pine Tree, don't look so pathetic," Bill falsely whined. He ran his gloved fingers down Dipper's chest, causing the young man to gasp.

Dipper sat up on his elbows and looked down at himself. He knew Bill had tore at his clothes, but he had no idea how much the demon had torn away. His shirt was in ribbons and his pants, they were barely holding together. He shot a glare at Bill, only causing the man to laugh.

"I may have gotten away with myself," he snickered. He pressed his hand fully against Dipper's chest and pushed him back on the bed.

Dipper growled and swung his fist, connecting with Bill's jaw. He didn't know exactly what came over him, but he wished he did this a while ago. That was, until, a burning sensation came from Bill's hand on his chest. He cried out in pain and tried desperately to move Bill's hand.

Slowly, Bill turned his head back toward Dipper with a small glare. "I'm pretty sure that wasn't a form of foreplay on your behalf," he stated coolly.

The burning pain stopped as Bill moved his hand. Gasping, Dipper forced himself back on his elbows and looked at his chest to see a blackened triangle. "What. The. Hell," he bit out, glaring weakly at Bill.

Bill glared back smugly. He didn't say anything as he rubbed Dipper through his pants again. "Still hard," he hummed.

The blush from earlier returned and Dipper harshened his glare. "Fuck you."

"Maybe later," Bill countered, leaning down to the black mark on Dipper's chest. When Bill stuck out his tongue, Dipper closed his eyes. He waited for the enviable pain, but was surprised as shock of pleasure raked through is body as Bill licked across the mark. Dipper moaned loudly and fell back to the bed, stunned as the pleasure kept shooting through his body even after Bill's touch was gone.

"What was that?" Dipper gasped.

Bill chuckled, pulling off Dipper's hat and brushing back the hair from Dipper's forehead. "Just a mark," he answered vaguely. "But, I will warn you, don't let anyone else touch it."

"Why?"

A slow grin, malicious grin formed on Bill's face. "It'll hurt like hell."

Dipper's jaw dropped. "WHAT?!" Did Bill just put at mark on him that will most likely end up with him curled up on the floor in pain?

"Oh, you like it!" Bill teased, tracing along the edges of the mark.

"LIKE HELL I-Oh god," Dipper moan as Bill rubbed his hand across the mark.

"You really should watch that mouth of yours, before I put it to better use," Bill threatened lightly, taking back his hand.

Dipper almost whined at the loss of contact. He stared up at Bill as the demon started to undress himself. His heart thundered in his chest. This was really happening. He was going to have sex with Bill, a flying Dorito.

Bill noticed Dipper's eyes when he stared to unbutton his shirt. "Want to help?" he 'winked'.

Dipper grimaced. "Bite me," he spat.

Bill's smile dropped before smirking. "In a minute." He pulled off the shirt and tossed it to the floor by his vest and jacket. He looked down at Dipper's barely clothed body and removed the rest, causing the boy to give an undignified squeak. "That's better," he cooed, smirking as Pine Tree tried to cover himself. He grabbed the slightly bruised wrists and easily moved them back above the young man's head. "Now about that bite," he whispered.

Dipper visibly paled and tugged hard at his trapped wrist. "Please, I-" he muttered, but his voice broke when Bill leaned down, kissing his shoulder. He whined and tried to shrink away from the kisses.

"Calm yourself, Pine Tree," Bill whispered against his neck.

"How can I when you-Ah!" he cried out as Bill sunk his teeth into his shoulder. He bucked up, earning a groan from Bill as he tried desperately to dislodge Bill's teeth from his shoulder. "Bill!" he yelled as the demon bit down harder, breaking through the skin.

Bill finally released the skin, licking his lips as he sat back up. "There, happy now?" he jeered with a bloodied grin.

"NO!" Dipper shouted. He wanted nothing more than to slam his fist into the side of Bill's face again.

"Do you want another bite?" he asked with a small frown.

"No," he said firmly as he tried to back away from the demon.

Bill sighed and rolled his eye. "Are you ever happy?"

"Not when you're around," Dipper hissed.

Bill stared at him for a long moment and didn't speak until Dipper started to feel worried that the demon would decide to hurt him. "Well, we'll just have to change that, won't we?" he state, grabbing Dipper's bare hips and pulling him closer.

"No, WE don't," Dipper denied as he failed to pull himself back from Bill.

"Fine. I will have to change that," Bill sighed dramatically as he placed his hand back on the black mark, causing Dipper to gasp as he arched off the bed.

Dipper bit his lip hard as he tried to ignore the waves of pleasure that went through is body. "I'd rather you not," he grunted and rolled out from under Bill's touch.

Bill allowed the movement, grinning as he watched the boy roll onto his stomach and crawl away. He wrapped an arm around Dipper's waist and pulled him into his lap. "I suppose you would not," he coincided, laughing as the young man tried to wiggle out of his grasp. He ran his free hand down Dipper's side, grazing a few scars left from his little adventures in the woods. "But you really should know by now that I won't go back on a deal that I want to complete." His hand ran over the lean pale thigh, watching as the boy shivered when he touched the softer skin on the inner thigh.

"Wait…you want this?" Dipper more or less squeaked as he kept a close eye on where Bill's hand was going. Bill sighed across the back of his neck.

"I thought that much was obvious, Pine Tree," the demon said, disappointment obvious in his tone. "Why else would I even jump at your poorly executed deal?"

"I-I don't," Dipper stuttered as he tried to figure out a good reply, but Bill's hand kept getting closer. He grasped the sheets tightly for some sort of grounding, only to nearly fall on his face when Bill traced his tongue up the curve of his back. This is a bad idea, his mind screamed as Bill placed light kisses along the slick trail.

Bill kept a close eye on how Pine Tree reacted to each touch. The boy was obviously deprived of matter of the flesh. He nipped at Dipper's shoulder blade, enjoying as another shiver took over the young man's body. "Just relax and enjoy this, Pine Tree," Bill cooed in the boy's ear. "You don't have to give anything in return."

"T-tell that t-to the mark on my chest," Dipper hissed as Bill trailed a finger up his member, brushing the tip gently.

Bill grinned, seeing the breaks in Pine Tree's resolve. "I can remove that after we finish," he stated. "I'm my mark would help this in being immensely more enjoyable for you." He waited patiently for Dipper to answer. His body kept perfectly still as Dipper's shook deliciously.

"F-fine," Dipper sighed and that was all it took. Bill's hand that held him around the waist, slid up his chest and to the mark. Gently, the tips of Bill's fingers rubbed the center of the mark. Dipper arched into the touch with a gasping moan. His head laid back on Bill's shoulder, giving the demon the perfect opportunity to sink his teeth into the unmarked skin. Unlike the pain before, the bite sent spikes of pleasure that made him shake. "B-bill," he gasped as he moved against the hand that was still teasing his erection.

Dipper whimpered as Bill pulled back from the bite. "You really are needy, Pine Tree," he purred, wrapping his hand around the erect member.

"S-shut up," Dipper hissed as he thrust into the hand.

"Now that's just rude," Bill teased as he moved his hand slowly, brushing his thumb over the tip. "And I've been so nice." He slowed his hands, listening closely as Dipper whimpered again. "I do think I deserve an apology."

Dipper tried to move himself in Bill's hand, only to have the grip around him tighten painfully.

"Apologize," Bill whispered into his ear. Dipper turned his head to him, breathing heavily as he glared through heavy eyes.

"Bite. Me," he growled.

Bill blinked back in surprised. "I already did. Twice."

Dipper glared even harsher.

"But, apology accept," he grinned before placing a kiss on Dipper's sneer. Dipper returned the kiss hungrily as pull started to pump him with quick, firm movements. He swallowed each of the boy's moans, refusing to let go of the other's mouth. Just as Dipper's body started to tense, he released his hold and let the young man fall to the bed with a startled cry.

"W-what the hell?" Dipper asked between gasps of air.

"We're not done yet, kid," Bill replied hurriedly as he undid his pants.

"Well I hope not," Dipper grumbled, aching for release.

Bill rolled his eyes as he shimmied off his pants. "Just be a good boy and put your hands on the wall," he more or less ordered.

Dipper glanced back at him as he hesitantly moved to his knees and put his hands on the wall.

Bill's eyes gazed over the unmarked back as he kneeled between Dipper's legs, spreading them a bit more. "Keep your hands on the wall and don't move them unless I tell you too," he commanded.

Dipper grumbled something in return, but didn't move his hands. He listened as Bill shifted some more before he heard the sound of bottle opening, causing him to shift uncomfortably on the bed. "Bill?"

"Shush, Pine Tree, just trust me," Bill murmured as he warmed the cool liquid on his fingers.

"I doubt that's a good idea," Dipper muttered as his nails dug into the wall.

Bill laughed. "Not really," he replied as he ran a finger down Dipper's back and into the crevice of his backside.

Dipper shivered as Bill's finger circled his hole. "Bill, I don't-" he was cut off by his own groan as Bill slipped the finger in.

Bill moved the finger slowly, slicking the skin as he thrusts. As the hole loosened, he pressed another finger in, watching as Dipper pressed himself against the wall gasping for air. His fingers stretched him with smooth, slowly thrusts that the boy soon pressed back against. Adding a third, he searched for the small bundle of nerves the human male sex usually held.

A startle moan came from Dipper when Bill brushed against the nerves. Now knowing where they were, Bill pulled out his fingers, much to Dipper dislike, and grabbed the bottle next to him. Slicking himself with one hand, Bill placed his hand on Dipper's lower back. "Take a deep breath," Bill said as he positioned himself. He didn't move until Dipper breathed in. He plunged deep into Dipper, smirking as the boy cried out in pain and pleasure.

"BILL YOU ASS HOLE!" Dipper screamed, shaking against the wall.

Bill leaned over, kissing Dipper's shoulder as he reached around to the mark. "You say the sweetest things," he snickered as he rubbed the mark gently.

"I-I hate you," Dipper groaned, hating how much he was enjoying the touch.

"Again, so sweet," Bill said as he nipped at Dipper's ear. While rubbing the mark, Bill pulled back and slowly pushed back in, enjoying the way Pine Tree clenched around him. "Oh, Pine Tree," he moaned and he kept his pace slow. "You really have a deluxe body."

Dipper hid his face as his cheeks darkened. "Shut up," he muttered.

"Oh, but you are deluxe, my boy!" Bill grinned as he picked up the pace. "The way your body quakes at my touch." He rubbed harshly at the mark, making Dipper shiver as he moaned. "The sounds you make." He thrust against the bundle of nerve, groaning as Dipper clenched around him. "And the way you feel," he purred.

"Bill," Dipper whined, matching with the demon's thrusts. His hands itched to wrap around his erection and finish himself off. He was so close.

"The way you taste," Bill continued, licking at the bite mark on Dipper's neck. "So luxurious." His thrusts became more erratic the faster he moved. "I don't think I'll be able to give you up after this, kid," he hummed, dragging the nails of his free hand down Dipper's side. Elated, he listened to Dipper cry out against him as he came. Bill quickened his uneven thrusts, ejaculating inside the boy.

"Bill?" Dipper muttered weakly.

"Yes, Pine Tree?" Bill whispered, gasping for breath against Dipper's sweaty back.

"Can I move now?"

Bill tilted his head up to see that his Pine Tree looked ready to pass out. "Of course," he said, trying to smirk but yawned instead. He pulled out, causing Dipper to wince. Once Dipper laid down on the matrices, Bill fell next to him with an arm draped around his chest.

"Are you…are you going to take the mark off now?" Dipper sighed as he pulled the blankets up around them.

Bill shook his head. "No," he yawned, smirking when Dipper glared at him. "I was thinking about adding another or two…maybe five."

"Don't you dare," Dipper hissed, wincing as he tried to move at the demon.

Bill chuckled. "I won't, for now." Dipper looked unconvinced. "Go to sleep, Pine Tree," he said, placing his hand on the mark, making Dipper fall instantly asleep. He stared at the sleeping body of the teen, brushing the hair out of their sweaty face before wrapping his arm back around the young man's waist and falling asleep himself.
