Admit It, Dipper

by Lonely Fanboy48

After going through a cave, Wendy and Tambry's bodies grew in all the great spots. Dipper couldn't keep his eyes off of them while his sister offered them and him to go to the lake, alone, in their swimsuit and bikinis.

Dipper and Mabel arrived back at Gravity Falls, but only for the weekend. Summer is returning in a couple weeks and the weather continues to get warmer by the day. The twins agreed to spend the weekend at Wendy's place to prevent meeting Soos and Melody until they went over to their place for the Summer. They didn't want to spoil their reunion, so they agreed with Dipper and Mabel's parents to have their kids sleepover at Wendy's place.

"We're here." Mabel walked up to Wendy's cabin with her brother by her side. "My friends should be coming over soon."

"They will, They're probably savoring the moment like we're doing right now until Summer." Dipper smiled.

"You're just tempting my adrenaline!" She shaked.

"I'm also getting tempted, you're not the only one."

"Just nearly ten months of waiting felt like ten years."

"It'll be worth it, give it a couple more weeks and celebrate with candy." Dipper wrapped his arm around Mabel.

"Yeah, candy really brightens up the mood. Let's meet Wendy now." The two walked up to the front porch as Dipper knocked on the door. After waiting for ten seconds, he knocked on the door again, but neither Wendy nor her family answered it. "Huh, it seems she's not here."

"That's not true, she did say she was staying until we came here." When Dipper turns the knob, it's revealed to be unlocked. "Huh?"

"She forgot to lock the door?" When the two came in, heading straight to Wendy's bedroom, only to see her nowhere in sight. "Wendy?" She called. "We're here."

Dipper also felt confused from the disappearance of Wendy. He did miss her, but not as much when he used to have a crush on her. He still has her hat on while she has his, in fact, it'll be her first time wearing her hat going around Gravity Falls, unlike last year when he and Mabel left.

"Maybe it's best if we wait here since she won't worry about finding us."

"Then maybe when we hear her open her bedroom door," Mabel closed Wendy's bedroom door. "We should scream surprise to her."

"Okay, I'm sure it won't take her long to come back." Then much to their surprise, they heard walking outside of the bedroom.

"Spoke too soon." She whispered.

The two hide behind Wendy's bed as they hear Wendy and Tambry talking through the bedroom door. As Wendy opened it, Dipper and Mabel did their que. "Surprise!" The moment Dipper laid his eyes on Wendy, he thought she would be the same like last year, just a little taller. But apparently, she's taller, but her changed body caught his attention more, including her friend Tambry.

"Wow?" Mabel reacted. "Did puberty hit them more over the last year?"

"You could be right." Dipper blushed.

Wendy and Tambry have bigger chests and bigger hips, to the point that they're almost completely different people than how they were last year. "Hi Mabel, hi Dipper." Wendy waved. "Sorry for not being here, we've…been going through more Gravity Falls weirdness."

"But not the monster danger kind." Tambry added.

"We went into a cave and…well…you can guess what happened."

"You two turned into adults?" Mabel guessed.

"Yes adults."

Dipper couldn't look away from Wendy, she's hotter as an adult than when she was a teenager. The cave itself made her body better than he imagined from his fantasies he used to have of her. "So…what are we going to do since we're all here?" He asked.

"We were planning on hanging out with our friends, but from how we look," Wendy and Tambry looked at each other.

"We're like high schoolers near graduation." Tambry added. "Except we got modeling jobs before that."

"You got more than modeling jobs." Dipper replied. "But you're right. If we go anywhere in Gravity Falls, people won't look away from your…new affliction."

Mabel didn't ignore a word her brother said. In fact, it wasn't a surprise Dipper would be attracted to Wendy again. "Say, what would you two do rather than hanging out with friends?" She asked.

"I really don't know." Wendy replied.

"Anything at all."

Wendy's worried there's still a possibility if she and Tambry are out in public filled with people at any time. She doesn't know how long this effect will last, if not forever. Ever since she and Tambry left the cave, they've been having this summer-like feel despite the season not arriving yet. "We're mostly in a swimming mood."

"Really…" Mabel smirked as she looked at her brother shaking with the idea of Wendy being in a bikini for the first time. "I've heard the fishing season won't happen until Summer and the lake has no one there…maybe you, Tambry, and my brother should go there."

"Okay, we can go there."

Dipper blushed, with Wendy giving his sister her approval. "How about we watch movies instead? Like old times?"

"You really think we rather watch terrible movies than swim?" Tambry guessed. "You know Gravity Falls has zero quality movies right?"

"I know."

"We're gonna be the only ones there, Dipper, no need to be worried." Wendy smiled. "We would still go swimming, with or without this problem."

"It's not that, it's just I'm gonna end up like the people who…"

"It's just the three of us, relax."

"I don't think he will." Tambry commented.

"Don't you wanna come Mabel?"

"I'm gonna wait until my friends come here. That's what I'm looking forward to more than swimming." Mabel answered. "But my brother would be happy to come!" She wrapped her arm around his shoulder.

"Mabel!" Dipper reacted while taking her arm. "Can we talk outside?" He took Mabel outside of Wendy's room while also closing the door. "Mabel, what are you doing?"

"I thought you would enjoy yourself."

Dipper then placed his hand on his forehead. "First of all, I'm not a swimming guy, second, we're here to spend time with more people than just Wendy, and third." His blush still didn't go away. "Wendy's still hot!" He spoke quietly.

"And you think that's something you wouldn't enjoy?" Mabel placed her hands on her hips. "This could be your only chance to hang out with her."

"Weren't you the one who told me to move on?"

"I wasn't being judgemental."

"Mabel…"

"Okay, I was, but that doesn't mean I wasn't a sucker for it. Plus…"

"You have multiple crushes? Including Sev'ral Timez?" Dipper guessed which caused his sister to blush. "It's not really a surprise especially when you kiss Mermando on the mouth?"

This gave Mabel the advantage, but not in a way of getting back to her brother. "But you know it'll be a surprise if you actually kiss Wendy, and not on the cheek."

Dipper couldn't get that image out of his fantasy ever since he laid eyes on Wendy on the roof. It's impossible he can't end that fantasy if he gets it, unlike his sister who had luck with the boys. "Uncle Stan really gave me terrible advice on the girls during the roadtrip." He replied.

"And it didn't take long until you went back to Wendy all over again." She then placed her hand on his shoulder. "I'm giving you your space, is that a sign of an opportunity in front of you?"

"Yeah but…we know she's too old for me, and her turning taller makes no difference."

Mabel then turned to Wendy's bedroom door, knowing she and Tambry were still in her bedroom. "You know you're never getting a girlfriend more beautiful than Wendy. Even Pacifica could friend zone you."

"Now you're just making me feel like I'll never get any chances." Dipper then made his way outside the front door where he and her sister came in. As he sat on the porch, Mabel opened the bedroom door with Wendy and Tambry watching down on her.

"We heard everything, don't ask." Tambry responded.

"But…I'm not gonna lie…" Wendy crossed her arms. "I never spend time with him since the whole bunker situation, aside from the apocalypse."

Mabel then entered Wendy's bedroom while sitting on her bed. "You didn't have anything to gain during your spare time?"

"Without a boyfriend, big time." Wendy still couldn't un look the way she is. As if she and Tambry could stay this way forever. "Then again, my family always stresses me out, I just wish there's a way I can feel happy in a free spirit way."

This then gave Mabel a smirk, knowing she can give her brother free spirit happiness. "I think I can help you with that."

For about an hour, Mabel and Wendy left to head to town to go shopping, leaving Dipper and Tambry at Wendy's home. They both sat on the front porch with Wendy not being the only person Dipper is attracted to. As Tambry paid attention to her phone, Dipper couldn't look away from her breasts, as if they were the same size as Wendy's. However he also remembered that she's in a relationship with Robbie thanks to his sister. He hasn't dealt with him since Wendy broke up with him and he doesn't want to go down that road again.

Then Mabel and Wendy came back with a bag in Wendy's hand. "We're back!" Mabel called.

"And we're ready to head to the lake soon." Wendy cheered.

"Did anyone notice you?" Dipper wondered.

"A couple, but for now at least."

"Plus, we also found something for you to wear Dipper." Mabel replied.

"Oh no." Dipper looked at the sky. "Did you pick it out?"

"Actually, she picked it out." She pointed at Wendy as she laid her eyes on him.

"I think you'll enjoy it. Let's go inside Tambry." Wendy then heads inside with Tambry getting up to follow her.

Dipper stood still, as if Wendy was pulling a prank, but never a rude prank like his sister. "I'm starting to think she's getting too comfortable with her grown body."

"Aren't you?" Mabel smiled.

"You know I don't swim to have a great time like you Mabel." Dipper sighed. "But it's gonna be hot when I get to the lake, and it's not just Wendy…and…Tambry."

"Come on Bro-bro, you're enjoying it as much as they are. Just be in the spirit, it's not that hard."

"I just never knew how it'll feel."

"First time for everyone."

After Wendy and Tambry changed in the bathroom, Dipper did the same. They hid their swimsuits underneath their clothes to reveal them upon arriving at the lake, including Dipper, who couldn't believe what he was wearing. The three left Wendy's place, leaving Mabel all alone as they made their way to the lake. Dipper made sure he walked in front of Wendy and Tambry, making sure he doesn't get distracted from their behinds, however this only made Wendy more prepared.

"So, this is your first time swimming?" Wendy smiled.

"Yes, did your job last year give you more swimming time before you got fired?" Dipper wondered.

"I was a lifeguard, I only swim if it's an emergency."

"Also, this is my first time swimming, so we all have something in common." Tambry commented while still looking around. "There's still no one around, you think this is a good idea?"

"Family time doesn't always happen in the lake until Summer happens."

"True, but don't you think going to the pool is less of a risk then swimming in the lake?" Dipper asked.

"You know we're banned from there right?"

"Not me, but I wouldn't go there alone." Tambry replied.

"What about Robbie?"

"We broke up after you and your sister left."

As if the opportunity couldn't get any better, Dipper's in the position of two single adult girls without worrying about a boyfriend who could rip his head off. Instead of causing another outrage similar to Wendy for going out to bowling, he avoids by not telling her what really happened, as if it could be worse.

"Well…seems the lake's gonna put us all in the spirit." He grinned without turning around.

"With the lake being bigger than the pool, there's a chance I will."

"We all will." Wendy replied.

Eventually, they arrived at the Lake without a person in sight, including inside the only building there. They all walked at the end of the dock to witness the waterfall, far off in the distance. Even if no boats were available, they still got a great view of the waterfall.

"You have to admit that the waterfall's really beautiful." Wendy smiled.

"Yeah." Dipper responded. "When there's no fog, it looks better than a painting."

"Even better from a picture online." Tambry commented.

"We're never gonna swim all the way there, but it's not like anything's waiting for us over there." Wendy turned around while heading to the side of the dock, with Dipper and Tambry following. Dipper knows there's no turning back now. The swimsuit he's wearing underneath his clothes is more embarrassing, but he's aware Wendy picked it out especially for him. "Well, we should be taking our clothes off then."

"Wait!" Dipper shouted while calming down. "Did Mabel tell me that your whole body turns against you? As in…growing from private parts?"

"Eww! Don't talk about hairy parts." Tambry retorted.

"He means our skin, not hair." Wendy crossed her arms while still smiling.

"Oh, nevermind."

"No Dipper, what I meant is getting sick from bacteria. Also, this lake never had any dangerous bacteria."

Dipper couldn't disagree, but if he tried to stall, Wendy and Tambry would eventually catch on. "Sorry…I just can't believe we're really doing this."

"Dude, you're having fun, just as much as we do. It isn't the beach but…" She then took off her hat while placing it on the ground. "I'm loving the mood I'm in."

Wendy unbuttoned her shirt, while Tambry also took off her shirt. Dipper only took off his hat, not anything else. All he did was watch Wendy and Tambry take off their clothes with no one spotting them. With both of them out of their pants, they toss their clothes to the side, revealing their bikinis which caused Dipper's whole face to turn red as a tomato. Wendy was wearing a green string bikini that matched her shirt while Tambry wore the same, but in purple. It wasn't the first time Dipper saw Wendy in a bikini, but the first with her adult body.

"How much of a mood are you in?" Dipper smiled.

"More, it's way better than I thought."

"So do I." Tambry looked at her own swimsuit. "I can see why ladies wear these."

"Come on Dipper, take your clothes off."

Dipper closed his eyes, shocked to believe Wendy, of all people said that out loud. He took off his fleece vest while slowly taking off his shirt. As he untied his shoes along with taking off his socks, all that was left was his shorts. When he looked at Wendy and Tambry, they both lidded their eyes, while placing their hands on their hips, watching him without wearing a shirt. He took a deep breath while pulling down his shorts, revealing his swimsuit. Just like his friends, he's also revealing more skin. The breeze blew on his body and legs while he covered his arms.

"You brought me swimming briefs?" He blushed.

"Yes, we're all showing off, we're not gonna let you be a third wheel." Wendy replied.

"Being a third wheel is the worst wheel and you can't deny that." Tambry added.

"You're right…" Dipper signed.

"Your swimsuit is still cute dude." Wendy walked up to him while leaning down. "This is gonna be better than our time by the pool last summer."

Dipper couldn't look away from Wendy's bikini, especially with her boobs closer to him. "Were you two aware that bodies change when you get older?"

"Everyone's bodies change, even yours." Wendy then places her hand on his exposed shoulder, taking him by surprise. "And I can tell you'll be like us when you become an adult, if you know what I mean."

Dipper shook which took Wendy by notice. "Well…I'm not an expert on modeling jobs but…I still have life decisions."

She then took Dipper's hand as she stood up, looking straight at the lake. "It's not a life decision, think of it as sensual freedom." She then moves her butt in front of Dipper, while slightly touching his nose. Dipper backed away, but he didn't look away. His eyes were mesmerized, with Wendy's buttcheeks being the perfect shape for a bikini model. "Say Tambry, show him your cheeks."

"Why now?" Tambry agreed as she walked up to Dipper, turning around while showing her cheeks.

"Would you mind taking his hand also?"

"Sure." Tambry took Dipper's other hand as Wendy whispered into her ear. Dipper didn't pay attention to Wendy, nor even notice that Tambry took his hand. All that he did was stare at Wendy and Tambry's buttcheeks. There are so many things he wanted to do in his fantasies but he never thought about doing it in reality.

"Hey Dipper." Wendy spoked as Dipper looked up, witnessing her and Tambry smiling. "When we get into the lake, would you mind splashing water at us?"

"You two aren't splashing with each other?" He asked.

"We will. Again, you're not just the third wheel."

"Not a thing adults should do, but we aren't starting any time soon." Tambry smirked.

They took Dipper to the lake with their feet dipping into the water. They moan from the temperature of the water with Dipper still staring at their rears. The movement from their walking made him think the weirdness they discovered wasn't a bad thing and more of a great thing in his mind. Soon, they reached to the level where the water's touching Wendy and Tambry's knees and Dipper's upper body, almost up towards his chin.

"Well, I'm not a third wheel, but it'll be awkward to splash you two like this." Dipper smiled while feeling the water all around him.

"Just go with it." Tambry responded as she and Wendy leaned down with their hands in the water.

Dipper did the honors by splashing Wendy and Tambry first as they closed their eyes, smiling with the water splashing into their hair. "Dipper!" Wendy cheered. "You have no idea how I wanted to get splashed!"

"Is that what you did during your childhood or is it your…" Dipper staring at her body. "...adult body feeling?"

As Tambry moved her hair, she opened her eyes. "Childhood, totally. Adult body feeling, also totally!" She also cheered. "We really love it."

"So do I!" Wendy giggled as she splashed Tambry and Dipper, causing Dipper to almost lose his balance in the water. Soon, Wendy and Tambry continued to splash with each other, getting their bikinis and skin wet in the process.

As Dipper regains his balance, he's about to splash them again. but he stood in place when his eyes were laid on them again. The sun reflecting through the drops upon each splash along with Wendy and Tambry's hair getting more soaked by the second. His legs were shaking to the point he couldn't control himself. Unlike the many times he was with Wendy in the past, this reached a level he never thought he could reach.

"How can anything get better than this!?" He thought.

Wendy and Tambry splashed one more time as they had enough, giggling as their whole bodies got wet. "I don't care what anyone says, this will never get old!" Wendy replied.

"I can never let any of this go, no matter how old we get!" Tambry added. "Our bikinis really fit our figures."

As Dipper remained still, Wendy and Tambry both looked at him, noticing him shaking without splashing them. "Admit it, Dipper, you're having way more fun than you're letting on." Wendy said, lidding her eyes.

"What do you mean? I only splashed you two once!" He reacted.

"More of a reason why?"

"Okay, it's your bikinis, and bodies! If you two were in your normal bodies with regular swimsuits, I wouldn't be this distracted."

It wasn't a surprise to Wendy and Tambry with Dipper being the only boy with them. "We know what we're doing." Tambry giggled.

"If we were swimming in our normal bodies along with regular swimsuits, we wouldn't do this." Wendy and Tambry reached behind their backs, untying their tops which caused Dipper's eyes to shoot open. He knew what they're doing but couldn't believe it's actually happening. Wendy and Tambry took off their tops, tossing them by their clothes with their boobs out in the open.

"I…am…really getting warmer right now!" Dipper stared at their boobs. With them out in the open along with the splashes, they were far more mesmerizing than seeing them from a porn magazine.

"Ohh…" Wendy moaned with the breeze blowing on her. "This feels way better."

"I bet adults who feel this way, love doing this." Tambry lifting her boobs up.

Dipper couldn't take it anymore. While watching Wendy and Tambry's tits, he reached underneath his briefs and started masturbateing. He had a secret he always kept from everyone, including his sister. He knew he wouldn't be the same Pines in the eyes of the people he met if they found out his secret.

"Dipper." Wendy smiled, causing him to get caught. "Wanna do something really fun?"

"Yes, who wouldn't!?" He pulled his hand out of his briefs.

Much to his surprise, both Wendy and Tambry raised their fingers to him, gesturing to him to come in between them. Dipper did the deed and as he walked up in between Wendy and Tambry. And then, they picked Dipper up from the water, with both of their boobs pressing against his arms, causing his whole face to turn red again while smiling, unable to control himself.

"I don't need to ask if you're enjoying this." Wendy looked closely at Dipper.

"He's about to insanely shake, just like his sister." Tambry added.

"She was always on a sugar rush though, Dipper barely had that."

"Bet when he does, his definition of a sugar rush, has to be totally savory."

They felt Dipper moving his body while he closed his eyes, feeling their boobs with their nipples on his arms, causing him to giggle. Wendy found his giggling cute, because he rarely does it. In fact, it was the first time she ever heard him laugh like that.

"So soft and perfect." He replied while still laughing. "You have no idea how happy I am."

"It's no longer a surprise." Wendy grabbed onto Dipper with Tambry standing by her side. "Admit it, Dipper, this is what you really wanted."

"Seeing us topless, you would never see that on my profile on the internet." Tambry smirked.

"Well…" Dipper looked down with his chest pressing against Wendy's boobs. "…It's unlikely for you to do that. Have you been thinking of doing this to your other ex boyfriends if you felt like it?" He blushed. "Including Robbie?"

"If they were better boyfriends, possibly, but not in these bodies." Wendy answered.

"Speaking of Robbie, we broke up because that lovely affection we had with each other, died down." Tambry said. "Not that I wouldn't do this in front of him, but you look way cuter when you giggle."

Dipper didn't think the love potion Mabel gave to Tambry and Robbie would ever wear off. And now he's the one who's getting Tambry's affection. "I haven't met other girls your age…but you're just as hot as Wendy." He then blushed while turning to Wendy, who smiled with her eyes lidded.

"Really?" She replied. "Hey Tambry, why don't you and Dipper lay together on the sand?" She handed him to Tambry.

"Why not, let me have some quality time with the boy who finds me hot." She lidded her eyes at him. They got out of the water with the sun setting towards the waterfall. Tambry put Dipper on the sand as she noticed the bulge in his briefs. She then laid her body on the sand while Dipper stood still.

"I'm not really the relaxing type, but I understand how people like you would feel relaxing by the lake." Dipper replied.

"We can help you feel relaxed." Tambry offered. "We want you to feel good like us."

"Okay." Dipper turned to Wendy who's still standing in the lake. "You wanna lay next to us, Wendy?"

"Maybe later." She placed her hands on her hips. "But first, we want to take another step further."

"What step?" Dipper then felt Tambry grabbed the two sides of his swimming briefs and pulled them down. "Ahhh!?"

With his penis in the eyes of Wendy and Tambry, they both giggled with Wendy placing her hands on her mouth. Dipper covered himself with him completely naked. "I know you've been doing that when you're alone." Wendy blushed.

"Thirteen year olds would always hide in their bedroom, doing their funny business." Tambry eyed his cock.

"This isn't what I had in mind! How did you two-" Tambry then covered his mouth.

"Just quiet down and relax, we're all in a safe place." Wendy said. "If we're all on the same page, just go with it."

"Just lay down, relax, and watch." Tambry led close to him, lifting his hands out of the way while grabbing his penis.

"Oh!" He reacted from the fingers of Tambry. He didn't want to put his clothes back on and leave, knowing he'll miss his opportunity. "Okay." He lay on the sand with his back. "But we're at the risk of getting…on the ri…" Tambry rubbed his member.

"Admit it, Dipper, give in and just feel it."

Dipper smiled from the feeling his member's getting harder, thanks to Tambry. He felt gazed while watching Wendy dancing in the lake. She lifted her boobs up with her arms while swinging her hips. Dipper felt like he was getting massaged by a lady with a sexy model giving him a show. Without his hands doing the work, his arms and legs felt relaxed with it being the first time he's feeling relaxed.

"I'm so into this." Dipper happily sighed.

"Keep giving in." Tambry slowly speeds up her motion.

Wendy adored Dipper's look, but there's one thing she has on. It'll be the point of no return, but she has a secret she kept from anyone, including her friends and ex boyfriends. She then turned around, showing off her buttcheeks again.

"Admit it, Dipper, you love our butts." Wendy turned around.

"Love is a powerful word…" Dipper slightly snapped out of his gaze. "It's just how I think of it, bigger than liking something so good."

"You can't get bigger than love." Tambry commented.

"I know love isn't easy to work out in a relationship…but feeling it is still awesome…" She grabbed the ends of her bikini bottom and pulled them down, bending over as Tambry increased the speed. For the first time in Dipper's life, he witnessed a woman's exposed pussy, from Wendy out of all people.

"I love you." He said out loud.

"Her butt or just her?" Tambry wondered.

"Her butt…"

As Wendy took off her bikini bottom from her feet, she heard what Dipper just said. But unlike her friend, she knows what his real answer is, but felt pleased from the answer out in the open. In fact, she wants to please him instead of dancing with her completely naked. She walked up to him, getting out of the water as Tambry stopped, slightly giving Dipper space.

"My butt huh?" Wendy blocking the sunlight. "When a redhead like me has freckles, you know you're in for a sweet treat and more fun than you really wanted." She turned around, showing off her butt, which grabbed Dipper's attention. What he wasn't expecting was Wendy preparing to sit down, but not by his side. She pressed her freckled butt on his member, causing it to throb hard.

"Oh my!" He reacted while smiling uncontrollably again, feeling her cheeks on his private spot. "I didn't think it was that smooth."

"Then your way easier to play with. This is just the beginning."

"Then go for it Wendy!" Tambry cheered.

Wendy went back and forth on Dipper's shaft as Dipper remained still with the end of his legs touching Wendy's thighs. He loved it more than Tambry giving him the handjob. Her cheeks feel great but to him, it turned his fantasy coming to life even more marvelous.

"Ohh…" He felt the sensation reach its peak. "If you know how sensitive I am, I would go harder."

Wendy turned on her shoulder while looking down on Dipper, still continuing her motions. "Your sensitivity is what's growing on me, and I wanna see your friend unleash hard." She went faster, while squeezing his member with her cheeks as Dipper curled his toes up, shaking in excitement. "I know the more sensitive you get, the more you'd love to go to town on me." She then moved her wet hair on Dipper's face, where he still smelled the shampoo and the clean lake water. As if it wasn't too much for him to handle while his dignity is lost, but not in the eyes of Wendy and Tambry. "Admit it, Dipper, you want to go to town on me."

As Dipper saw Wendy's face through her hair, he cummed from her cheeks, much harder than his private times as Wendy noticed. Even with it landing on her hair, she loved Dipper blinking nonstop. He couldn't stop cumming for how much he loves her butt and how smooth it is. He then started panting, while his orgasm ended, he laid his head on the sand while Wendy moved to the other side.

"Wow." Tambry looking at the amount Dipper released. "Sensitive boys really hold a lot of delicious love."

"You don't say?" Wendy used her finger to take some of Dipper's cum, while Tambry did the same. They put it in their mouths, tasting it with Dipper slowly opening his eyes. He saw Wendy and Tambry enjoying the taste of his semen, humming in delight.

"This wasn't what I had in mind." Dipper commented while blushing.

"How come? Your cum's really is delicious love." Tambry said, taking some more of his semen.

"Everything you feel about me can sum up by tasting this." Wendy also took more semen, tasting them in the process. "Good thing Robbie wasn't my first guy."

"Wait, so you mean I'm your first guy?" Dipper leaned up. "Especially when I'm thirteen?"

"It's not like you were trying to be better than them, you're better at being adorably sensitive."

"As if you couldn't turn red with your blood not doing the work." Tambry added.

"I can't help myself, it's hard to not smile when you're enjoying it." Dipper replied.

Wendy then turned and laid on her belly, looking straight at the lake while Dipper slowly got up. "Try to make me smile and enjoy this, we can keep going and stay here as long as you want. if it's okay with you."

After listening, Dipper looked at her freckled ass. He then turned to the entrance to the lake where he came from, still lucky no one had spotted him.

"I'm okay with it." Dipper turned back to Wendy.

Wendy then slapped her asscheek. "Go for it, dummy lover."

Dipper went in front of Wendy's ass, blushing as Wendy turned back to the lake. He also looked down at his penis, still throbbing, wanting more, but he also wanted something else. He saw Wendy's pussy in close view, causing him to lick his lips. "Now I know how Mabel feels when she wants candy." He wasted little time as he gently spread her asscheeks while digging in her slit with his tongue.

"Ohh!" Wendy blinked while feeling Dipper's tongue. "Hell yeah! Lick it really good!"

"You heard her, Dipper licker." Tambry sat on the sand, watching the action Dipper's doing. Dipper loved the taste from Wendy's pussy, his tongue licked in every spot it could all the while lifting his legs up. He licked deeper which caused Wendy to moan.

"Yeah!" Wendy shook her legs, while biting her lip. "You're not the only one who's sensitive. I've been waiting for this feeling!"

Dipper squeezed himself with Wendy's cheeks, smelling her booty as if her being the only daughter in her family makes her really aromatic. He turned his attention to her sweet spot, not hesitating as he licked it, being his favorite taste. Wendy slightly shook her ass, just moments of reaching her orgasm, but she wouldn't have imagined that anyone would be better than Dipper in this scenario.

"I haven't taken off my bikini bottom yet but that feels really great huh?" Tambry replied.

"Trust me, there's no regrets, he makes this so good!" Soon, Wendy closed her eyes in delight, moaning with her orgasm squirting into Dipper's mouth. As her juices entered inside Dipper, Dipper tasted it while looking up from above. He loved it just as much as his favorite foods, he knew it would take time until he gets to the moment he wants to reach, but he isn't backing down for how he's enjoying it. As he leaned back, he swallowed the juices while Wendy took deep breaths. "My pussy had never felt so alive."

"Damn Dipper, you're a licking machine." Tambry smiled. "You licked the fun into her."

"That's how much I love her." Dipper replied. "I don't think I'll ever find a girl who'll have that taste. It's way better than I thought."

Wendy slowly, but surely sat on the sand while she grabbed Dipper's arm, taking him by surprise. She placed her arms over his shoulders with her hair on his right shoulder, she touched his penis while her breast pressed against the back of his neck, causing him to blush.

"You're right and I don't think I'll ever find another person who made my summer awesome last year." She looked at Dipper, blocking his sunlight, with her eyes closer to him. "I've been thinking about you ever since you left and to be honest…you're not too young to me."

"You're serious?" Dipper giggled.

"I'm still flattered even when I'm too old for you. You make me way more happy from the way you went to town on me."

"It's you who has the full package, I wouldn't pass out on anything I could do."

Wendy expected him to say that as she turned to her friend. "She's not the only full package." She got on her knees, facing Dipper while placing her hand underneath his chin. "When I never spend this time on my phone, you know you're in for what I'm really made of."

She finally took off her bikini bottom, placing it by the rest of her clothes. As she turned around, Dipper stared at her butt, while Wendy knew what he's thinking. "Give her what you gave me. Every girl is different in their own way." She then started stroking him as Dipper shook. Wendy's hands were a lot more softer than Tambry's, to where his penis leaked a little, which got Wendy's attention. "Go to town with my friend, we'll go to more levels than you think."

Dipper licked his lips again, following what Wendy said as he divided his tongue into Tambry's pussy. Like before, he licked every spot while enjoying the taste of Tambry's inner walls. Tambry bites her lip while feeling the sensation in her clit. "This boy is growing on me hardcore!" She reacted.

"Just wait once you reach your limit." Wendy continued to stroke him. "If our bodies stay like this for a little longer, I want to be in Dipper's place to lick you."

"Then I wanna lick yours."

"Win win."

Dipper increased his speed, putting his attention on Tambry's sweet spot just like Wendy, as Tambry was close to reaching her limit. She then placed her hand on the back of Dipper's head, getting him closer as she couldn't control her legs. "I'm losing my virginity over a thirteen year old boy. I won't trade it for anyone else!" She then moaned at loud as she squirted in Dipper's mouth. Dipper can taste the difference to where Tambry's juices are good in its own way. Tambry slightly twerked, while savoring the sensation. Despite it all going away, she still loves the after effects, something she enjoys when a party at her place finished its finale.

Tambry took some steps away from Dipper as she landed on her front on the sand, lifting her butt in the air. "I don't need to ask what you felt, Tambry." Wendy smiled, without a response from her friend.

"You two have amazing juices." Dipper sighed. "I'm so frazzled."

"We don't blame you, but now you feel what people do when they lay under the sun by the lake." Wendy stopped stroking his penis as Dipper was close to reaching his second orgasm. Wendy leaned back from Dipper as he turned around. "How are you feeling?"

"Better than the last time." Dipper looked at his penis.

"Then I bet it'll feel better like this." She pushed him on the sand, allowing him to place his penis in between her boobs.

While still feeling the sensation, Dipper's legs shook while Wendy positioned his legs underneath her armpits. "I can't even tell I prefer your chest or your butt!" He squealed.

"There's always an option of picking both." Wendy smiled as she rubbed his penis with her boobs. "We're not giving you limits, since we don't have many."

Dipper laid back on the sand, while Wendy continued to give him a boobjob. Despite not looking at her, Dipper still remembered how good her boobs felt, as if they were made to be good upon adult age. He twitched his toes, each time his dick slid back in. "No limits…more love!" He reacted.

Tambry turned around, witnessing Wendy giving Dipper a boobjob. She really wanted to replay him back from the moment she had from him. With her and them officially naked, she wasn't going back, especially with her personal liking towards Dipper. As Dipper got close to his second climax, Tambry appeared in his vision, while she looked down at him. She positioned herself next to Dipper as she leaned down towards him. She pressed her lips against Dipper's, causing Dipper's eyes to shoot open. He thrusted in between Wendy's tits from his real first kiss all the while he shot more cum out of his penis.

"Tambry!" Wendy giggled, with Dipper's semen shooting on her.

Tambry kept the kissing going while Dipper's lips felt like it was marrying the bride. He wanted Wendy to be his first girl to kiss on the lips, but he never thought Tambry was such a natural kisser. As he stopped cumming, Tambry broke the kiss as Wendy got out of her position. With the boobjob and kiss, Dipper felt like he finally got his dream love life, something he thought only his sister would get.

"I love you Tambry." He spoked. "I have two crushes now."

"Admit it, Dipper, you had a crush on me the moment you saw me in the bikini." Tambry placed her hand on his cheek. "I'm thankful you didn't find another girl while kissing you like that."

"That is, if a girl his age kisses him that long." Wendy leaned next to her.

"It's not that I was trying to move on with my life, I just don't think a girl of my age would be willing to kiss me on the lips." Dipper commented. "Especially like this."

"You learn more when you get older."

"You still think you can keep going?" Tambry wondered.

"Probably." Dipper answered. "I'm thankful we're still not getting spotted."

"It's better than getting arrested." Wendy smiled. "I think we should do some teamwork together."

"We haven't done that, let's do it." Tambry agreed.

The two stared at Dipper's cock, the only thing they didn't do is what ladies would do when they went for it. Tambry moved Dipper in front of the lake as the sun set over the waterfall. "Admit it, Dipper, you know full well, no one is ever gonna spot us." Wendy leaned next to Dipper on the right.

"It's like we have the whole lake to ourselves." Tambry leaned to the left.

"Okay, I can't deny no one will ever see this." Dipper confessed. "It's almost getting late for people to go to the lake, so I'm sure we're safe for just today."

"Oh trust us, we're more than safe." Wendy spoked. "Especially when we finally get a piece of you."

With full view, Wendy and Tambry stick out their tongues, licking his penis from the right and left. While he remained still, Dipper got more ticklish for how good their tongues are, all the while making a cute giggle yet again. Wendy and Tambry licked every spot on his shaft, enjoying the taste from the tip and bottom. Not to mention they accidentally licked each other's tongues, but that gave them two things for the price of one.

"Ohh, I really wonder what girls really feel when they do this!" He smiled. "You two are the only ones who keep me going and going while I'm still all in for it!"

Wendy and Tambry didn't respond, still focusing on Dipper's penis, but they still heard him. They would prefer licking him over licking a lollipop, a snow cone, or even ice cream. They even touched one of his balls with their fingers, as they're getting tighter, signaling he's reaching his third orgasm, bigger than the last, but they kept their passionate session, working hardcore as a team, savoring the taste together.

"Here I come again…" Dipper panted. "So much love…so much Wendy…so much Tambry…so much Adult SEX!" He came like a laser beam, so high, it got Wendy and Tambry's attention as they stopped but Wendy grabbed his shaft to have him keep the fire power.

"It's like a water sprinkler!" Tambry smiled with cum landing on her.

"This is way cuter for a boy to do." Wendy commented. When she's still masturbating, Dipper's eyes sparkled in delight, thrusting in the air with his third orgasm reaching to grand sensations.

With the fire power died down, love is all inside his body, more than his sister whenever she encounters a boy to her liking. With his cum all over Wendy and Tambry, they licked it while enjoying the taste again.

"If we had more female friends, they would love to do this." Wendy licking more cum.

"If they were with us in the cave we went, totally." Tambry said.

"You don't know how happy I am." Dipper sighed. "This isn't being a man like from the Manotaurs. This is being a man in freedom."

"Now you know how I feel when I need to be myself." Wendy replied. "I'm not skipping any of this once I become an adult for real."

When Dipper slightly got up, he still had some energy to do more. He's still attached to Wendy and Tambry's asses, knowing he won't be able to do it back at Wendy's place, nor anywhere else. "Well, we don't know if the effects are permanent. But if it is, you two would love doing the next activity just as much as I am." He held onto his own arm, blushing.

"What are you thinking about?" Tambry lidded her eyes.

"Tell us, and we'll do it." Wendy leads close to Dipper.

"I want…to thrust into…" He tried to finish his sentence, but Wendy placed her finger on his lips.

"Our butts?" She guessed. "You think we would skip on that, do you?"

"We wouldn't be here if we didn't." Tambry added.

"And besides, we would love to have you sleep in the middle with us in bed."

Even when he got the opportunity, now another opportunity is just two orgasms away. "Let's do it!" He screamed.

"I'll go first." Tambry laid on her front, with her butt in full view of Dipper.

Dipper jumped onto Tambry's thick butt as he slid his cock inside her pussy. "Give her everything you got dude." Wendy patted Dipper on the back.

"Yes…your penis is big enough to do it."

Dipper wasted little time as he thrust back and forth, feeling the inner walls of Tambry. With this being his fourth orgasm, it got harder for him to reach the sensation he's reaching. But he kept going to not leave Tambry disappointed.

"I don't know- ah, you're so- ah, brave to do this." Tambry commented.

"Would you be willing to go for it if you threw a party like this?" Dipper asked.

"I'm brave, but- ah, not like this."

The sensation continued to pick up in Dipper's penis as he continued to sweat. With slaps from his thrusts to Tambry's asscheeks, he started to shake, catching Wendy's attention.

"I know that feeling." Wendy grinned.

"I can feel it." Tambry closed her eyes. "But I'm gonna feel it more when he comes inside me!"

"Don't give up Dipper, give her the bomb."

Dipper went faster while his penis shot ounces of cum out. "You don't know how I picture the bomb when it happens!" As he thrusted more and more, Tambry felt more of his ounces. She squeezed her asscheeks, praying to Dipper to release at any moment. "And how much why girl butts are more important than boy butts!"

After another minute, Dipper came inside Tambry's ass, causing her to lift her legs. "Yes! Yes! YES!" She cheered.

"The backdoor is my door babe!" Dipper added. He slowly thrusted, as he leaked his final ounce inside. He slid out while landing by Tambry's leg. "I can not believe I just said that."

"You couldn't believe that?" Wendy replied. "You just stuffed her like a boss."

"This will be my new obsession over my phone." Tambry sighed while feeling her insides. "I'm totally sleeping with you tonight, Dipper."

When Dipper tried to get on his feet, his crotch hurt, causing him to land on his knees. "Dipper?" Wendy took notice.

"I'm sorry- ow!" Dipper placed his hand on his crotch. "My lower body is hurting me."

"You really released a lot."

"I'm a licking machine, but I'm not a squirting machine." He then placed his hands on his knees. "I don't think I can do this."

Wendy knew Dipper would be drained, even with him being his happiest. But she isn't leaving the lake, she knows Dipper wants it, and so does she. She placed her hand under his chin, giving him eye to eye contact. "Admit It, Dipper, you want me as your girlfriend, instead of being your friend."

"Okay, I admit it." Dipper replied. "It's just impossible to let go when it's really important for my age. But when you took me here, you showed me a side that you would only do for guys your age."

Wendy then turned to Tambry, who's oozing semen out of her. "You just cheer up, we're gonna do the bomb, you're just losing your confidence. You never did that every time you tried to impress me last Summer."

"You know it's a huge difference."

She then leaned close to him with her eyes lidded. "But if there's one thing you haven't learned about me, it's that I never lose my confidence. And when you don't lose your confidence, it makes me wanna make out with you." She gave him a kiss on his lips.

Dipper reacted in an instant while Wendy grabbed him by his head, preventing him from breaking the moment. Dipper lost control from his body due to the kiss Wendy planted on him. Her lips weren't natural like Tambry's, but magical in Dipper's fantasy. To where his own imagination's becoming just like Mabel's. But his own world with his own happiness.

Wendy can feel the love from Dipper, even with her eyes closed. And she knows she'll feel it more after he gives her his. She broke the kiss with Dipper mesmerized by her. "Come on dude, you know what to do and what I want."

"Don't back down, you can go through one more round." Tambry said, getting back up.

Thanks to the kiss from his crush, Dipper's energy surged back into him. "It may hurt me, but it won't hurt you."

Wendy got on her front, while showing off her ass. Dipper slowly made his way, climbed into her back thighs while looking at her wet slit. He inserted his penis as Wendy moaned. As he regained the pace he did with Tambry, Wendy couldn't get enough of Dipper's penis going in and out of her.

"Everytime I think of the next boyfriend I'm in a relationship with, I always wonder how they would please me like this." Wendy commented. "But now you are my number one banger, if you know what I mean."

Dipper continued to thrust into her faster, while placing his hands on her buttcheeks. Even with his sore crotch, he isn't backing out for how much he loves Wendy. He wants to give her the load she wanted, after she gave him the greatest time at the lake.

"The more it hurts…the better it feels!" Dipper reacted.

"I know you won't bleed and neither will I, don't stop banging!" Wendy cheered.

The sensation returns, five times better as Dipper's blush also returns. Every time his penis felt it, he couldn't control his emotions. All he can think of is masturbateing with the one and only girl in Gravity Falls who turned into an adult. And now he can do the same with her one female friend.

"I'm getting close." He panted.

"Just- ah, shot- ah, the- ah, TARGET!" Wendy shouted.

With his crush cheering him on, Dipper regains the pressure in his penis as he's seconds away from cumming. "I love this! I love this!" He repeated with each thrust. "I LOVE YOU WENDY CORDUROY!"

"OOH DIPPER PINES!"

Dipper unleashed the load of all loads inside of Wendy's womb. The sensation inside Wendy's ass felt more legendary in reality, putting his fantasy to shame. Wendy lifted both of her legs up in delight, accidently pushing Dipper in her pussy. For her first ever cream filling, Dipper made himself a pro in her book.

"So…good!" Wendy smiled.

"OH- Oh- ohh…yes…" Dipper sighed, as he stopped in place while still inside Wendy's pussy. His fifth orgasm finally stopped, even with a sore crotch, he wouldn't be able to top what he just accomplished.

"Damn." Tambry stood up after watching the show. She pulled Dipper out of Wendy, as she oozed out Dipper's semen. "If there was a banging contest online, you would've won first place."

"I can't disagree." Dipper replied. "I think competition won't be a problem if the right people are paired."

As Wendy got on her feet, she looked at Dipper after the load he gave her. Even while sweating from the action, she still didn't feel drained from her body, unlike Dipper. "If we were paired, we would also win the cutest pairing, if you were also my age."

"If only I became hotter like you."

"Sexier is a better term thanks to your firepower." Wendy pinched Dipper's cheek.

"My private time has been hiding a lot of mysteries that weren't meant to be mysteries." He blushed. "Anyway, I think our time here is done."

"We can still stay a little longer. We only went in the lake one time after all."

With no sunlight and no supper, Dipper didn't feel hungry even if he waited for Wendy's family to order pizza or something upon arriving. "Then again, Mabel's friends probably took her out for supper for how late we are."

"I barely get to school on time all school year, we're found something to eat before bed." As Wendy received Dipper from Tambry, they know what they're gonna do next. "Let's dirty up the lake."

"Big time." Dipper smiled.

Dipper, Wendy, and Tambry jumped into the lake from the dock with a big splash. They spent the next hour skinny dipping in the lake, showing off with their tits, while having Dipper suck on their nipples. When it got dark, with the stars appearing from the sky, they put their clothes back on, heading back to Wendy's place. After having supper from the leftovers Wendy had from last week, Tambry texted her parents she'll be sleeping over at Wendy's as she and Wendy cleaned up in the bathroom.

After they entered Wendy's bedroom, Dipper took his time to clean himself up, after the time he had today. Despite still smelling the odor from the lake water on himself, he earned his chance to sleep with Wendy and Tambry. His soreness hadn't gone away, but it healed a bit from the past hour. The only thing he'll enjoy overnight is being cozy with him being in the middle between them. After brushing his teeth, he heads out while turning off the bathroom light. When he made his way to Wendy's bedroom door, he noticed Mabel waiting by it.

"So?" She asked. "How was your day with Wendy and Tambry?"

"Amazing." Dipper confessed.

"Bet you know how I feel towards my crushes."

"It's just I never expressed myself like you do."

"Because you were once single." Mabel pinched his cheek. "But not anymore."

"Mabel, if they didn't go through the cave, I'm sure I wouldn't be with them, I would've slept with you."

"We slept during sleepovers back home, I still would've skipped today if you just asked."

"Yeah, I would've asked." Dipper reconsidered. "If you were actually with us, you wouldn't believe what I did with them."

"Then you should be thankful since I gave you space. I would've watched the whole show, aside from swimming in the lake."

Dipper knew Mabel would probably make fun of him if she tagged along. But for how nice and respectful her twin sister got over the last nine months, he knew she would change, even by a little.

"I'll admit this ended up becoming my day…even if it's by pure luck."

"Sweet pure luck." Mabel grinned. "Something I always have for charm." She then yawned as she headed to the living room. "See you in the morning."

"Good night Mabel, and thanks." He turned to Wendy's bedroom door while opening it. However the moment he entered, all the while closing the door behind him, he stopped in place while witnessing Wendy and Tambry in their underwear. "W-Wendy!? T-Tambry!?"

Both Wendy and Tambry shushed him, lucky enough no one heard them. "You just saw us naked earlier." Tambry smiled. "We just want to make you feel more comfortable."

"And Dipper," Wendy walked up to Dipper. "It's better sleeping in underwear than pajamas. Admit it that you never sleep in pajamas."

Dipper blushed, knowing Wendy's right. "Yes, but every time you and Tambry say admit it, you mostly drag me into it."

Wendy then picked Dipper up, placing him on her bed. "It's not dragging if you're enjoying it." Tambry placed her hand on the mattress.

"And Dipper." Wendy smiled. "Admit it."

"Admit what?" Dipper asked as he witnessed Wendy and Tambry smiling.

They grabbed into his clothes, stripping them off, including his underwear. Dipper blushed with him being naked again. "That you want to sleep naked with us."

"And with us naked as well." Tambry added.

Dipper was about to cover himself but at this point, he's no longer embarrassed after his secrets and dreams were exposed in front of them. "Yes…" He giggled. "I admit it."

This caused Wendy and Tambry to remove their bras and panties, Wendy turned off her lamp as they all tucked into bed with Dipper sleeping in the middle. "Wanna make out?"

"How can I say no to that?"

"Not to your two girlfriends." Wendy pressed her lips against his.

Dipper gave in while pressing his body against her breasts. After that, he also kissed Tambry on the lips as she grabbed a hold of his cock. "You're getting leaky again, boyfriend." She broke the kiss.

"It's a good thing I brought birth control pills, otherwise, we wouldn't have done what we did, nor did more." Wendy stared down at Dipper. She and Tambry both kissed each other on the lips from above their boyfriend.

"You two made me the happiest boy in the world." Dipper commented as Wendy and Tambry broke the kiss, looking down at him.

"And you made us the most affectionate ladies of the world." Wendy smiled.

"Happy to make you that." The three make out all the while masturbateing, enjoying their moment during bedtime. Eventually, they fell into slumber with Wendy and Tambry wrapping their arms together, with Dipper in between. Dipper may have to wait a couple of weeks to stay at Gravity Falls for the Summer, but with Wendy and Tambry's bodies possibly staying this way permanently, this Summer could be better than last year's. All the while having two girlfriends who one, will have her Summer be the greatest thanks to his affection. And how it grew on her erotically.
