Pinecest: Aged Up Remix(WIP)

        Dipper stared at the dusty, wooden wall as he waited for his sister's breathing to slow down and become heavy. He was ready to begin his nightly masturbation session, but he had to make sure that Mabel was asleep before he could do the deed. Minutes passed as the girl began to snore, giving Dipper the signal to stroke himself in the darkness. He roughly gripped his raging boner, squeezing it a bit as he slowly jerked himself. A few years had passed since his adventures in Gravity Falls, but he just couldn't forget that fateful summer. And the best thing that weighed on his mind after all those years was Wendy. His mind ran with fantasies about a still fifteen year-old Wendy and her tall, slender body, pressing her small bosoms into the teen's face. He gasped softly as he imagined he saw Wendy lick the tip of his throbbing cock, moaning as she rubbed her moist pussy, his fapping become faster and a bit more frantic as he mentally fondled her ass. Then, as he got ready to enter his crush as she lay on her side, he was interrupted by his sister's voice.

        “Dipper.” He nearly jumped out of his skin, hiding his hard-on as he threw his comforter over his lap. “OH! HEY! Yeah, umm... Just finishing this essay! Yep!” He chuckled nervously as lay on his side, trying to play it cool, but she just looked at him, her face red and a bit fearful.

        “Yeah, I see that. Looks like.. fun?” The girl's eyes gazed at the noticeable mound sticking up from the sheets, her cheeks reddening as her brother rolled to his stomach to hide his member from her prying eyes. Smooshing her cheeks with her hands, she looked at Dipper's mortified face as he settled down, shutting his eyes as hard as he could. Mabel waited for a few moments before awkwardly asking Dipper, “Do you need help with that?” Biting her bottom lip, she swung her legs over the side of the bed, sitting as she watched Dipper squirm on the nearby bed. Her heart pounded like a drum as Dipper silently broke out in a cold sweat.

        He couldn't believe that someone was finally offering him something that he had wanted for a while.

His fifteen year-old mind always had sex tucked into the back of his mind, silently wishing for the chance to lay into some cute girl's thighs. And now, he had such a chance. But of course, it just HAD to be Mabel. He had to admit that hid sister was cute, and he did find her a bit physically appealing, her chest outfitted with small-but-perky breasts. But she was still his twin, even with her tits and growing thighs. She was his partner in crime and his best friend, and now she was asking for something as forbidden and weird as this? Hell no. Yeah, the thought of fondling Mabel's chest was popping up in his head, but it was just his dick talking. He had to make the sensible choice before his mind became corrupted by more dirty thoughts.

        Dipper sat up quickly, his face ablaze and his mind fuzzy as he faced his sister. And as soon as he prepared himself to refuse her offer, he noticed Mabel was trying to stealthy rub her panties as Dipper was turned around. She froze and tried to play it off as an itch, but now his dick was raging with desire, and his mind turned to thoughts of fooling around with the girl. Unable to take stop himself, he nodded to her. “Yeah... Yeah, alright.”

        Mabel stared back at him for a while, chewing on her hair as her brother scratched his head. Her mind was racing fast with disgust, fear, and arousal as she slowly slid off her bed, inching toward Dipper's. She just couldn't take yet another night of jilling off as she pretended to sleep. She knew they both had needs, and this was an opportunity that very few people had. Climbing in her twin's bed, she decided to push out the thoughts telling her to go back to bed and pretend that this never happened.

        Dipper moved the sheets away from himself to reveal his turgid prick poking against his boxer shorts. Silently, Mabel pulled down his waistband and watched as his member popped out, hard as a diamond. They both held their breaths as the girl firmed grasped it in her hands, feeling the meat stick pulsate softly as she begin to rub it. Unsure of how to proceed, she began to lick the tip of his dick, her crotch growing moist as she began to give her brother a clumsy blowjob. Quickly pushing his pole into her mouth, she began to bob and suckle on as much her mouth could take.

        Dipper had to stifle a gasp at the sensation of his sister blowing him. His sister was constantly kissing and licking his head as she tried to emulate the women she had seen on her father's "Secret Locked Channel". Maybe it was good that she could guess his passwords, no problem. She was doing a mediocre job at giving him head, but the boy was still feeling a great of amount of pleasure from her mouth. His turmoil about messing around with Mabel was now gone, and he decided to continue this foreplay some more.

        The feeling of Dipper's warm length thrusting into her gullet and the taste of his skin as she ran her mouth down the side of his length turned the girl on immensely as she began to roughly fondle his balls. However, unlike her brother, she still felt disgusted as she dragged her tongue on his shaft. How could she be doing this, and to her own twin? I mean, the sight of his hardened dick did turn her on a bit, but it wasn't him she wanted.  She was in need of some relief, and he just happened to be close enough to provide. And yet, it was her brother she was sucking off. It was all fucked up, and she didn't know whether to stop or to keep going, whether to touch herself and take her time or to hurry up and finish him off. As she engaged in internal turmoil, Mabel didn't notice Dipper reaching down and fondling her left breast through her long t-shirt. She instantly jerked her head up and saw Dipper's  face change from arousal to a shocked expression as he yanked his hand back.

        “Shit, sorry!” he hastily blurted out before quickly lowering his voice again as he turned his gaze away from her face. “Sorry, I just kinda grabbed it.” He  nearly hyper-ventilated as he waited for his sister's reaction. He was damn sure that she wasn't cool with him grabbing her like that. He waited for her to silently walk back to her bed and act as it none of this had ever happened, or to whisper to him to fuck off. Her voice broke the terrible silence. “It's okay, Dipper. Wanna touch them some more?” His head snapped back down to Mabel, who was softly fondling her chest as she once again grabbed his rigid protrusion. As he felt a familiar moist, warm sensation on his cock again, he slowly reached down and tenderly cupped one of Mabel's tits. The feeling of Dipper groping her milk mounds instantly disintegrated the fear and disgust she had felt only a few seconds ago, if only temporarily.

        “Mmmm...” Without even realizing it, she had begun to moan at her brother's touch. She began to slowly grind the air, her need growing more as she was fondled. She began to push Dipper's rod into her mouth again, her moaning growing muffled as she blew him. In the midst of her lustful murmuring, she heard a tiny whisper that broke her out of her trance. “Come on... Get up here,” Dipper whispered to his sister, as she gently pulled his dong out of her mouth and got up. Confused, she watched him sit on his bed, standing up herself as she saw him awkwardly motion towards her. She took a place next to him, her face beet red as the twins looked at each other. Slowly, Dipper scooted  next to her, his face nearing hers as they both grew closer. In a matter of seconds, their faces were only an inch or two apart, the still air of their bedroom the only barrier between the two. That barrier was soon  broken as the twins pushed their lips together and began to sloppily make-out.

        Now, this wasn't a little peck, or the sort of kiss that performed by lovers when they wish to show feelings for each other. This was a messy, almost disgusting clashing of the lips. The two moaned desperately into each other's mouths as they grabbed each other and began to feel each other up. Dipper began to furiously hump Mabel's leg as she roughly grabbed his ass with one hand and his hair with the other. The girl gasped and called for her savior as the boy roughly squeezed her breasts. He panted heavily as she felt up his smooth chest,  releasing their kiss for a moment for a tongue bathing session with his stomach before returning for another kiss. For a while, they went at it like animals, ferociously swapping spit while rubbing and squeezing their sibling. Soon, however, this burst of horniness and adrenaline wore off. And as it winded down, the two stopped their messily smooching and laid down on each other, the girl under the boy.

        Each sibling tried to think of something to say now that they had regained control of their bodies, but nothing could be said. Instead, Mabel put her head on Dipper's shoulder, and Dipper began to massage her leg. At this point, they were in too deep to quit. They had already broken a huge taboo, and there was no going back to normalcy after this. And besides, even with the slowly growing fear in their minds, they still felt aroused, albeit aroused and disgusted. They regained their energy over the course of 30 seconds, neither daring to look at the other in the eyes or to say anything. Then, as they regained their strength, their libido returned as well. Dipper slowly began to move his hand up Mabel's leg, rubbing on her thigh and the side of her slightly chubby rump. He continually moved his hand from the outside of her ass, to the inside of her thigh, and back out again. After only ten seconds of this, Mabel decided to cut to the chase.

        “Damn it, just do it,” she whispered huskily, opening up her legs a bit wider for him. It took Dipper only a second to take her up on her offer, and he pushed his hand back under her nightshirt. He ran his digits on his thighs a bit before sliding his hand onto her soaking wet panties. The girl tossed her head back at his touch, her sensitivity off-the-charts as he stroked her virgin pussy.  This continued for around a minute as Mabel writhed and squirmed at power of his touch. But while she was busy enjoying his hand, Dipper began to crave something else. He lifted up Mabel's shirt, exposing her panties to the room. He stared at the moonlit sight of his sister half-dressed, her erect nipples gently pushing against the fabric of her nightshirt, her underwear moist with her juice. On any normal night, he would simply look away as fast as he could and yell at her to pull her shirt down. But not this night.

        This night, he pushed his head between legs, hungrily lapping at her fluid spotted thighs.

        This night, he slid her panties down to her ankles, giving her a quick look to make sure it was okay. She was too busy massaging her chest to look back, so he took her silence as an OK to continue.

        This night, he stared at her moist slit with a rush of excitement, his manhood throbbing in his hand all the while.

        And this night, he drove his head between her legs and began to give her pussy a tongue lashing.

        Mabel managed to grit her teeth and cover her mouth just in time as her throat emitted lusty cries of pleasure. Hearing his twin's reaction, he dug in deeper, kissing her lower lips constantly as he explored her with his tongue.
