Dipper woke up in his bed. It was dark outside, and when he looked at the clock it read 12:00 a.m. The covers were pulled up around his shoulders and he snuggled into his bed, up against a warm, soft thing that was behind him, hoping he could get back to sleep.
Wait.
There shouldn't be something warm and soft behind him. He slowly turned his head, praying it wasn't something deadly, like a serial killer. Bill's florescent eyes shone in the dark, back at him. He nearly screamed, but Bill put a hand over his mouth just in time. Bill put a finger up to Dipper's lips, then pointed at Mabel. He gestured for them to leave the room. They got up and crept to the door, and once Dipper was outside Bill closed it softly. They walked together to Bill's room. Once they were inside, a flurry of whispers erupted from their mouths.
"Bill? Why do I have my body? Wha-"
"Oh, Pine Tree," Bill purred. "So very concerned about things, all the time. Why can't you just let a good thing come to you? But listen to us talking the night away. I had something else planned, you know."
"What did you plan?" Dipper asked, suddenly curious.
"Oh, my little Pine Tree, you can't just ask."
"What?"
"You have to make it special for me. Beg for it," Bill ordered. "Don't worry about noise, my room is soundproofed."
"Umm, okay," Dipper knelt down on the floor. "Please Bill, tell me what we're gonna do tonight, please,"
"Oh, come on, darling. You can do better," Bill said, his eyes turning slightly red.
"Oh, Bill, please! I wanna know what we're gonna do!" Dipper whined.
"Eh, you're getting there. But I still can't tell you. Not quite that good."
Dipper felt his heart race. He knew that if he didn't get out of Bill, there was no telling what might happen. Bill wouldn't have any reason to stick to what he originally thought of, and that means it might involve pain. Bill clearly wasn't thinking straight.
"Bill, come on! I wanna know!" Dipper pleaded, curling up smaller at Bill's feet. "Oh, oh, please?"
"Now we're getting somewhere!" His eyes returned to their normal yellow-goldness. "We're going to cuddle. I feel like I haven't touched you at all for awhile."
"Yeah, you haven't cause you were in my body!"
"What did you say?!" Bill roared, his eyes suddenly all red. Dipper scooted away from him, finding his back up against a wall.
"Nevermind, it's fine."
"Oh, okay," Bill said, eyes turning yellow once more. He walked over to his bed and sat down. "C'mere Pine Tree, I don't bite... you... yet." Dipper reluctantly stood up and smiled at Bill, walked over to him and sat down. Bill wrapped an arm around his lover's shoulders and kissed him lightly on the cheek. Murmuring into his ear, "Care to submit to me?" Dipper didn't pull away. Dipper also didn't know exactly what Bill was talking about, so he just froze. "Come on darling, you really thought we were just going to cuddle? I love you, but no. Just say you'll give me control, and I'll show you what we're really doing."
"Okay," Dipper whispered in suit, and Bill grinned.
"Just close your eyes until I say you can open them, and I'll take care of the rest." Dipper closed his eyes and felt Bill get off the bed. A moment later, he felt something being wrapped around his wrists, then feet. Dimly, he wondered what Bill was doing and if he should be worried, but Bill was right. He hadn't hurt Dipper yet. "Okay, Pine Tree. You can open."
As he suspected, he was tied up. His wrists were bound to each other, as well as his ankles. "Bill? Should I be worried?"
Bill started singing instead.
"Oh, little Pine Tree don't you cry,
Bill's gonna get you really high.
And if you still are sad,
Bill's gonna fuck you up mad.
And if you ever start to smile,
Bill's gonna keep doing it for awhile.
And if you ever like my screwing,
Well then I guess I'll still do it."
"In other words," Bill smiled at Dipper and walked over to him. "I hope you're not too worried about torture." He sat down on the bed next to Dipper and leaned in close, kissing him softly on the lips. Dipper kissed him back as best as he could. Bill threaded his hand through Dipper's hair, smiling into his lover's lips. Suddenly, he pulled away. Dipper whined. Bill smirked. He had power now. He unzipped Dipper's shorts and pulled down his underwear, letting his dick free from the cruel constraints of clothes. Dipper's eyes widened as Bill licked the tip of his phallus, which caused it to come to life. Bill bit down. Dipper screamed, whether in longing or pain Bill knew not. Bill giggled and ran his hands over Dipper's partially clothed body, digging his nails into sensitive spots like the inside of his thighs or his armpits. Dipper bit back a scream, then moaned and bucked his hips towards Bill when he bit down on Dipper's dick again.
"Oh, darling little Pine Tree, I didn't think you'd like that," Bill said, smirking.
"I hoped you wouldn't find out."
"I won't tell. I'll simply use it to my infinite advantage."
Bill wasted no time in putting the full length of Dipper's phallus in his mouth, making his partner moan again. He slid his tongue around, exciting Dipper's dick and causing it to grow harder and harder.
"Bill! I'm gonna..." he huffed a breath as Bill pulled Dipper's dick out of his mouth. Dipper whined, struggling around in his bonds, trying to get Bill back on him. Bill giggled as Dipper whined again. "Come on Bill! Don't be an asshole!"
"You're such a whiner when you're turned on. But you haven't given me anything yet. Before I'll make you cum, I need to some of that famous Pine Tree sex."
"Okay, okay, get over here!" Bill worked his way up to Dipper's head slowly, making Dipper whine once more. "Come on Bill!" Dipper urged him on, as Bill finally got up to his head. "What do you want me to do?" Bill smiled.
"Let me take off my clothes first. Patience, my little Pine Tree." Bill pulled off his shirt and for once, Dipper was silent, stunned by the tanned, lean body in front of him. He nearly drooled as Bill unfastened and pulled off his pants, then underwear. "Suck me, and I want you to swallow it all."
"Yes, Bill," Dipper said. Bill shoved his phallus down Dipper's throat, nearly choking Dipper. Dipper bobbed his mouth on Bill's dick, causing Bill to moan softly.
"Damn Pine Tree! I didn't kno-" Bill interrupted himself with a moan. "-ow you were... ohhhh... so good at this." Dipper didn't respond, just focused himself on sucking Bill. Bill moaned again and again, bucking his hips to get Dipper farther down on his phallus. Dipper went faster and faster, as just seeing Bill in such a state was enough to make him even more erect. He wanted to get this over with so Bill would finish him. Bill moaned one last time, and with a huge spasm, cummed into Dipper's mouth. Dipper swallowed it quickly, gulping it down, and nearly choking himself with every swallow. He lapped up all the excess that had leaked out of Bill's dick, all around his body. Dipper licked Bill up and down, his legs and torso, and most importantly, his pelvis. Bill took himself out of Dipper's reach.
"Are you gonna finish me now, Bill?" Dipper asked, his voice calm but his eyes betraying the need for this to happen.
"I don't know..." Dipper whimpered. "Well, I guess." Bill smirked at him and crawled back down to Dipper's pelvic area, biting down on his leg. Dipper moaned, his need for Bill more than overflowing his mouth. Dipper started to make small sounds that turned into whimpers, ones that sounded like a dog asking for food. This metaphor stuck in Bill's mind and he stowed it away for later use. For now, he finally guided his mouth back down to Dipper's dick, smiling as he flicked his tongue on and off the tip and Dipper moaned. He dug his fingers into Dipper's soft belly and sucked on Dipper's phallus, pulling his mouth off it as Dipper finally climaxed, letting out a huge moan.
"Oh, Bill," Dipper breathed.
"Little Pine Tree, I enjoyed that. You can expect another night such as this sometime soon." Dipper didn't know whether to be frightened or excited, but the thought of seeing Bill naked and tempting again was certainly a treat. Bill crawled over Dipper, releasing him and telling him to go back to his room. Dipper nodded and got up, trying to decide how to feel about Bill's sex methods. There was a lot to consider, and as he walked back to his room he figured it would be necessary to make a pro/con list.
"Hello bro. Where have you been?" Dipper nearly jumped out of his skin when he saw Mabel, sitting up in bed wit a flashlight on under face, giving her horror movie lighting.
Dipper closed the door behind him. "I... uhh... nothing?" He said, sitting down on his bed. "I'll tell you some other time. I wanna sleep."
"No! Tell me now, Dip Dop! If you don't tell me now, you'll never tell me."
"Fine, fine. I was just getting a midnight snack."
"For an hour?"
"Hey, I eat slow."
"I think you were doing inappropriate things.
"Mabel, that's crazy. I don't like anyone."
"Yes, you do. You like Will."
"No, I don't."
"This isn't a thing you're arguing about with me. I'll ask Will in the morning if he knows what you were doing last night. I'm sure he'll be flustered enough to answer me honestly."
"Okay, Mabel." Dipper had no doubt in his mind that Bill would hide things even better than he could. He went to sleep comforted by the idea that everything would be safe from everyone. He and Bill would keep their secret and the world would stay innocent.
The next morning, Dipper woke up with the distinct feeling something was not right.
