During the day the forest seemed to welcome everyone to come and play, but at night the forest seemed to dare anyone to come and see what's hidden within the shadows. He didn't mind the forest during the night, in fact he was grateful for it since he would take a moonlight walk to clear his head every single night. He was thinking about the days events when he stop dead in his tracks. He heard something, Was it a voice? Was it a animal? Then he realized what it was, it was most beautiful noise he ever heard. Then it hit him like a lightening bolt to his heart, "she's here" his whisper in a breathless tone. He realized that she was some where in the forest. He followed the magical sound as if a sailor was being lured to a siren.

The wind gently beating him on his back as he kept following the sound. Then he found her, his breathing became shallow as he watched in awe. There she was stark naked bathing in the moonlight water. Her red hair was glistening in the moonlight as tiny droplets fell on to her breast which were full of bounce with red cherry nipples at full attention. He pink lips playing peek-a-boo as she spread her long lean legs. Her skin glowed underneath the stars as the seemed the stars and moon were the spotlight and the water was the sage. He watched as her hands ran across her body to touch and wash the parts as if she was performing for an unknown audience.

He only dreamed he would be able to touch one day her so he could perform with her in sync. He was imagining doing all the sweet things to her when he paused. She was softly moaning his name and the performance became more angelic. His name never sounded so angelic before as it fell from her lips over and over again. He was shaking a little bit now from the cold thin air as he constitute to watch in secret. Time seemed to stand still as he watch her thinking about him in the most sinful ways. "Oh Dipper!", she was shouting now. Her lips opening wider and wider, her hands moving faster with every breath she took. "Dipper! Dipper! Dipper! Dipper! DIPPER!" Dipper's eyes shoot open as he saw his sister on top of him shaking him to wake up.

"Dipper come on wake up it's time for our 16 birthday!", Mabel was shouting at Dipper. "MABEL! What are you doing! I was in the middle of having a very uhhhh nice dream!", Dipper blushed a little when he remember the context of his dream. Then he realized that he had morning wood and it was poking his sister. He prayed to go that she didn't noticed anything.

Mabel knew that Dipper was dreaming about Wendy since he talked in his sleep from time to time, she giggled in respond. Until she realize that she was on top of her twin bother and that his Little Dipper was poking her innocent lips. She blushed a little bit but at the same time she noticed that she got a tiny bit excited at it poking her. She shook her whole body at the thought of her thinking about her bother in that way.

Dipper took a deep breath as his sister shook a little. He felt himself pre-cum a bit, he felt himself get red at the thought he had. ''Oh god she's my sister I shouldn't be thinking like this, in fact my twin sister!" Dipper snapped out of his thought when Grankle Stan came barging in with party hats and sparklers. Stan was about to say happy birthday when he noticed how the twins were position. Mabel his niece was on top of Dipper she was strangling his thigh area. She was wearing a bright blue skirt with a matching bright blue sweater that had "Sweet 16 Girl" written on it in pink. Her hair was being held in a pink ribbon, her hair fell down beautiful in soft waves down her back. Her breast seemed to be fuller then normal, that's when he realized that her nipples were poking though her sweater. Mabel didn't really like to wear bras from time to time so sometimes she went bra-less, no one really thought nothing of it. She had curves that could drive any man wild. Stan smiled since he realized that she has grown into a beautiful young women, but still had that cute and perkiness from when they first got here.

He noticed that she was blushing so hard that her face was bright red and the he took a look at his nephew Dipper who was underneath his sister. Dipper seemed to just have woken up from the looks of him. Dipper had his shirt off, and Stan realize that Dipper must have been working out a bit because he looks a buff but not too buff just like the right amount of buff. What Stan didn't know was that from all the monsters Dipper got a pretty good cardio workout from it. Dipper had hair that went to his ear and brown eyes that seemed to whisper secrets. Dipper was no longer the little boy who was shy and scared. He was more of a young man and had the scent of adventure to him, or as Mabel would like to call it his BO. Stan looked at Dipper's face which matched his sister with the blushing, but Stan thought Dipper's blush a tad bit darker than Mabel's.

Both Mabel and Dipper noticed that their uncle came into their room, but they didn't dare to move frighten that their uncle might yell at them. They knew that the position they are in looked wrong from someone else point of view. Well it looked wrong and it felt wrong from their angle too. But both of them knew that even though it was wrong it just felt so right. Silence seemed to cover the room as no one dared said a word to another. The clock was ticking on the wall as it seemed that hours went by when in fact only 5 minutes went by. Stan cleared the silence with him clearing his thought.

"Well you kids seemed to like each other more than bother and sister. And were going to give each other the best present anyone could give another person. Or Mabel decided to wake you Dipper.", Stan said trying to lighten the mood but that only made things more awkward. Dipper came to his senses finally and practically threw his sister off him. Which made Mabel landed face first on the floor. Mabel groan a little bit at the pain. Waddles heard it and went to Mabel and began to rub his tiny little pig's nose on her. Dipper was watching Waddles rub his nose on Mabel. That's when Dipper noticed that Mabel had painted Waddles on the side which had the words "Happy Birthday Dipper and Mabel!" He also noticed that Waddles had a little party hat on too.

"Mabel! I'm really really sorry Mabel! Are you okay?",Dipper asked with concern in his tone.

"Ya I'm alright Dipper, but you know Dip you could have just ask if I could get off of you silly!",Mabel said in a carefree tone. Mabel took note of Waddles and began to play with him. Stan just stood there in awe thinking how the two of them just forgot about the whole thing and just went back to normal. ''Well that's how they are, I guess'' Stan thought but both kids were thinking the same thing ''Why did it feel good? And what do I do about it?''

"Well kids remember that today is your guys birthday and that around 6:15pm there's going to be a surprise from me! But this morning there's a surprise from your parents downstairs so hurry up and get ready!", Stan said as he went out the door. Dipper decide to help Mabel get off the floor. Mabel grabbed Dipper's hand and felt her heart skip a beat when she took Dipper's hand. The both stood in silence as they tried to think of a way to explain about what just happened. They couldn't just talked about it in from of Stan that would only make things more awkward.

The silence was broken by Dipper who said "Well I uhhhhh Mabel I know you may have felt uhh something",Dipper was blushing like crazy as he was trying to make things less awkward with what happened since his sister felt him and he felt his sister's wetness.

Mabel blushed a deep shade of red and stutter slightly as she said "Its alright Dipper I uh shouldn't have been on uhhh top of you. And also sorry if you felt uhhhh something..." They both stood there in silence avoiding each others eyes.

Finally for what seem for ages Dipper cleared his throat and touched the back of his neck. "Well I think I'm going to go take a shower then",Dipper said trying to escape from the awkward silence. Dipper went to go get his clothes and then headed to the bathroom still avoiding Mabel's eyes. As soon as Dipper locked the bathroom door. Mabel let out a huge breath that she didn't realize she was holding in. Mabel sat down on her bed with Waddles and started to talk to him.

"Waddles I think I like Dipper, like more than a friend more than a bother really! Waddles have you ever had that feeling before?",Mabel said to Waddles. Waddles just looked at Mabel with his cute pig face. Mabel laughed and said "You're right Waddles maybe it's just all in my head!" Mabel began to play with Waddles and Waddles just wiggled with joy.

Meanwhile Dipper was in the shower thinking about his dream that he had last night. He remembered how Wendy looked and how she was moaning his name. ''I only wish that it would happen in real life'' he thought. He began to think about the dream that it made him excited again and Dipper began to touch himself. As his mind escape thinking about Wendy he kept going and going. Until in his mind the girl changed her hair was long and brown, and had a sweater on. Dipper got more excited than he ever had before. As his hand moved faster up and down. His heard rate speed up. THe girl in his slowly turned around and that's when he realized that it was his sister. His eyes shot up and he dropped his hand as if his Little Dipper was on fire.

. ''Holy shit! I was thinking about my sister! And it turned me on more! You know maybe in the heat of the moment it just sort of happened. No big deal then, right?''Dipper was thinking about it and decided to just forget the whole thing. He got out of the shower and made a plan to finally ask out Wendy on a date since he was 16 today. Wendy was 18 years old, but he still thought he had a chance with her. Dipper smiled and headed out the door. Once he was out the door he was almost caught of guard. Mabel had practically trampled him to give one of her famous bear hugs. Dipper laughed and so did Mabel. Dipper then took a deep breath and took in the aroma of her hair which smelled of strawberries.

Meanwhile Mabel did the exact same thing but only Dipper smelled of fresh pine cones. They both were wrapped up in each other hugs and just smelling each other fragrances. They didn't care that to other people it may seem weird, but to them it was normal. Then all of a sudden Waddles came over to them and laid on both of they feet. The two of them broke apart and looked down to their feet to see Waddle. The roomed filled with laughter and the sound o joy. They left the room playfully hitting each as they went downstairs to see the most wonderful surprise ever.
