It was a cold stormy night in the water tower, Wakko and Dot were sitting together in front of the TV watching old cheesy Slappy cartoons from the 60s and Yakko was off recording a song in some far off location. Yakko had called them earlier saying that he'll be home a day or two late because of the storm. So, with nothing better to do, the duo of Wakko and Dot sat in front of the TV.

"It's getting awfully late, think we should turn in?" Dot asked Wakko.

"You go ahead, I'm going to stay here and watch some more and maybe get a snack," replied Wakko.

Typical Wakko, Dot thought to herself but she supposed he couldn't be stopped, especially if he was planning something with food. Wakko was an eating machine and nothing could get in between him and food, except maybe Yakko.

The sudden thought of Yakko saddened Dot but at least he'll be home tomorrow, she thought.

"Fine, but don't stay up too late and don't eat my ice cream again, ya hear?"

"Yes ma'am!" Wakko replied and mock saluted Dot, even if he had no intention if doing what she asked.

"Good, goodnight Wakko."

"Goodnight Dot."

Dot got up, went to the room, got her night gown then made her way to the bathroom. Once there she promptly took off her skirt and underwear and checked herself out in the mirror. This was her nightly routine and once she finished admiring her own lady parts she walked over to the toilet, put the lid down, sat on it and spread her legs. Dot was at the point where she masturbated almost everynight, she had been for a few years, so this was nothing new to her but she did try to keep her thoughts fresh and entertaining, just so she could cum quickly and go to bed. What or who was she going to think of tonight? She thought. Perhaps Scratchansniff? No, she'd already done him. How about Buttons? Naw, he's cute, Dot thought, but not really fuckable. Ralph the Guard? Definitely not.

"Hmmm," Dot audibly pondered for a while, she didn't want to dwell on it too long as it was getting late. Then one particular person came into mind. What about Wakko? Dot thought, at first she was surprised at herself for even considering it but she was running out of options. Besides, Dot subconsciously thought that her brother was pretty attractive and she did know what his most desirable parts looked like seeing as he didn't wear pants-

"Stop it, he's your brother for crying out loud!" She said quietly aloud, but that wasn't enough to convince herself. Well, she decided, I'm not really having sex with him and it's probably just going to be a one time thing. That settled it.

She slowly reached down between her legs and started rubbing her pussy, her eyes slowly closed as she imagined an image of Wakko in her head. She imagined his nice bare crotch and his superbly round ass. She slipped two fingers into her pussy as she imagined what it would be like to suck Wakko's cock, she had to cover her mouth to keep her from moaning too loud as a result. Dot started to thrust her fingers in and out of her pussy as she imagined what Wakko would feel like if he thrusted in and out of her from behind. These thoughts alone caused her to quake enormously as she quickly reached her climax, she wanted to call his name so badly but she did not want to alarm him or anyone else if they heard. The build up became too much has Dot arched her back and muffled her moan as much as she could as she came all over her hand and inner thighs.

Dot sat there breathing heavily for a while, that had been one of, if not the most, intense orgasm she had ever had. She looked at her hand and then her crotch area, both of which were soaked in her cum, did her thoughts of Wakko seriously get her that horny? She felt some shame but at the same time it awakened something in her that she seemigly had repressed for too long. Dot lingered on that thought for what felt like an eternity before she realized it must be really late, she promptly licked her fingers clean of the cum and used toilet paper to clean the rest from her thighs. She got into her night gown, brushed her teeth and got washed up before heading to bed.

As soon as Dot was out of sight Wakko sprung up and dashed to the kitchen, he went to the freezer and grabbed Dot's ice cream as well as a spoon before he dashed back to the TV. He sat down and continued watching his cartoons for a while, eating all of Dot's ice cream in the process.

After about and hour or two Wakko was burnt out on cartoons and he had finished all of Dot's ice cream. He got up and threw the ice cream bucket away as well as tossing his spoon into the sink before making his way to the room to make sure Dot was asleep. When he got there he looked in and sure enough, she was there fast alseep. Excellent, Wakko thought, now he could start his nightly routine. He went back to the TV and changed it to the "adult channel" and once he found something he liked he turned down the volume, sat down and watched. It was your standard porno except for one aspect, it was an incest porno. Wakko had just recently gotten into it and he found that he enjoyed it greatly, evident by his ever growing erection. He had fantasized about it by this point as well, and his thoughts were always on the only female in his family.

Wakko grabbed his fully erect penis and started rubbing up and down slowly as he watched the movie. The brother was giving it to his sister from behind, how Wakko would've loved to do that to his own. He went slightly faster, getting the precum that came off his tip and using it as lube. Wakko continued watching but slowly closed his eyes as he leaned his head back and started to imagine another scene, one where he was pounding Dot. He sped up his hand and started audibly groaning as he breathing got faster. His thoughts were plauged with images of him and Dot together and soon Wakko was getting closer and closer to his climax. He let out one last groan before covering his mouth with his other hand to muffle the noise as he started to cum all over himself. Wakko bucked his hips up as he came, getting cum all over his blue shirt and some even got on his face, but he didn't care, he was feeling so much pleasure at that moment that he didn't care about anything.

After Wakko's orgasm had passed he slowly opened his eyes and took his hand from his mouth. He was covered in cum, it was all over his shirt, hand and face and all he felt was satisfaction. When Wakko first fantasized about his sister he felt guilty and even disgusted at himself but now it felt almost normal to him and seeing him covered in his own cum reaffirmed that belief and made him ready for round two. There was always a round two for Wakko, but he needed time to recuperate before he started.

Dot was suddenly awoken by the loud sound of thunder outside, the storm was still raging on. She looked over at Wakko's bed for comfort but she only saw an empty bed. That's strange, Dot thought, why isn't Wakko in bed yet?

"He's probably still up eating my ice cream I bet," Dot said aloud, this annoyed her but she thought she should check up on Wakko, just in case. She kicked off her blankets and made her way to the living room. When she got there she saw Wakko's back as he was facing the TV. Of course, She thought, and he's eating my ice cream! She thought this as Wakko seemed to be moving his arm eratically in front of him.

Dot started walking up to him quietly, hoping to surprise him so she could catch him red-handed. But as Dot got closer she looked up at the TV and her heart sank. Wakko wasn't watching cartoons, he was watching porn! Which means- Dot went around to get a side view of Wakko and sure enough, his hand was on an erect penis going up and down at lightning speed and Wakko was already covered in cum from what must have been a previous session. Dot saw that his eyes were closed, which must be why he hadn't noticed her yet. All Dot could do was watch him, she couldn't avert her eyes. Wakko looked so cute with his face covered in his own cum and the amount on his shirt got her so horny. Most of all his penis was something Dot knew she wanted inside her, she had seen it before (Wakko doesn't wear pants after all) but this time was different, it was leaking precum and Dot herself was quickly getting very horny.

Dot decided that this was her only chance to make a move on Wakko without it totally failing. So, almost without thinking, Dot went up to Wakko and whispered into his ear,

"Whatcha doing?"

Wakko shot his eyes open and moved at an unreal speed to grab the remote and turn off the TV, he then covered his penis with his shirt but there was nothing he could do to conceal what he was doing anymore. Wakko was covered in cum and Dot must have already seen everything. Even so, with his face bright red, Wakko replied,

"N-Nothing! J-just watching TV is all..."

"Oh really? Then why did you freak out when I asked? You seem to be pretty adamant to hide what you were doing," Dot replied.

"Oh well, I-I-I just-I mean-"

"You don't have to tell me, I already know."

Wakko's face turned an even brighter red, "Y-You do?"

"mmmm yes, and I know what your're hiding under your shirt there," Dot slowly started to walk towards Wakko and he started to back up, unintentionally letting his shirt go and revealing his precum covered penis.

"Uhhhh I-ummm," Wakko replied, but stopped as his back hit the wall. Dot closed the distance between them and, lying down on her stomach, she crowled up to him and put her face inbetween his legs.

"It's ok, I've wanted to see it all night," Said Dot.

"Y-You have?" Wakko questioned.

"mmmm yes," Dot replied as she wrapped her hand around Wakko's throbbing cock. Wakko let out a sigh as Dot started to move her hand up and down. "Does it feel nice?"

"Yeah..." was Wakko's reply as he leaned his head back and closed his eyes. For the first time he wouldn't have to imagine his sister.

Dot continued moving her hand up and down slowly, with Wakko sighing and moaning in approval. Dot looked at Wakko's cock in her hand and, without warning, she slipped the whole thing into her mouth.

"Ah, Dot!" Wakko gasped in surprise, he opened his eyes and looked down. What Wakko saw was a scene he had thought would only stay in his own imagination. He saw Dot, with her eyes closed and a face full of his cock slowly bobbing up and down. Then Wakko noticed something that almost made him cum on the spot, Dot had her hand between her legs and she was slowly rubbing herself as she sucked off Wakko.

Wakko grabbed the back of Dot's head as he guided her in her bobbing up and down, "Oh god Dot, I don't think I'll last much longer!" Wakko cried as he quickly built towards his climax. Dot only moaned in reply as she kept sucking and rubbing her pussy.

"Oh my god, Dot I-AHHHHH!" Wakko screamed in pleasure as he held down Dot's head and started to cum inside her mouth. Wakko bucked into Dot's face as he let out load after load, with Dot swollowing every last bit greedily. Dot moaned and savored this moment, hearing Wakko call her name and his groans were pure pleasure to her. This wouldn't be the last time, that was for sure.

When Wakko had finished cumming he relaxed and leaned back in euphoric bliss. Dot took Wakko's penis from her mouth and she began to lick up what was left from his tip and shaft. Wakko giggled from this since it tickled him. When Dot had finished she looked up at Wakko and asked, "Did you like that?"

"Oh my god yes! It was faboo," Wakko replied in almost a dazed tone.

"Well guess what big guy, we're not done here."

"What do you mean."

"I mean what I wanted was to be penetrated, so penetrate me!" as Dot said this Wakko looked in surprise as Dot got up, turned around, lifted her night gown, and went down on all fours, revealing her luscious rump and pussy. Dot erected her tail and shook her butt from side to side, "Come and get it."

Wakko was instantly horny again, "Yes ma'am," Wakko said, he got up and mock saluted Dot.

Wakko walked up behind Dot and grabbed her hips with his left hand and his penis with his right. He guided his penis to Dot's entrance and he decided to tease her a little by rubbing his penis on her folds. Dot let out a needy moan and yelled, "Just put it in already! I've waited too long," Wakko always listened to his sister when she talked to him in that tone so he immediatly stuck his penis inside of her and he instinctively bucked all the way forward.

"Oh Wakko!" Dot cried, Wakko just grunted in reply.

Neither Wakko nor Dot could believe that this was actually happening, and it thrilled them both. Wakko slowly retreated his penis before slamming it back in. They both moaned and Wakko did it again, then again and before long he was thrusting in a steady rhythm. At this point both Wakko and Dot were in heaven, they moaned loudly and called out each others names. Wakko looked down and relished the sight of his cock exiting from Dot soaked in juices then being consumed by Dot's pussy. Dot, herself, was in pure euphoria and she could barely support herself as the pleasure was just so intense. Wakko couldn't stay straight any longer, he leaned down over Dot and held her torso with his left hand as his right made it's way down inbetween Dot's legs.

Dot felt Wakko lean over over her, as her tail was pushed down with him, and she felt him wrap his arm around her torso. But then she felt his other hand start rubbing the outside of her pussy in a reach-around and all she could do was scream, "Oh my god Wakko, YES! K-Keep going, p-please don't stop!" Wakko grunted in reply and he started to thrust faster. It was clear he was getting close to his orgasm.

"Dot," Wakko gasped," I-I'm getting close, c-can I-"

"Yes!" Dot screamed, "P-please! Fill me up!"

And with those words of encouragement Wakko started to thrust even faster.

"Wakko, oh god, Wakko I-I'm about to-to-AHHHHHH!" Dot screamed as she began to cum all over Wakko's thrusting penis. It ran down both of their legs as Wakko kept thrusting relentlessly.

Feeling his sister's cum around his penis and then running down his leg was all it took to drive Wakko over the edge.

"Dot! I'm...gonna...cum...too!" Wakko said in a struggling voice.

"Do it! Please Wakko hurry! I can't wait any longer!"

And with that Wakko drove his penis all the way into his sister as he came inside of her. Dot Called Wakko's name and moaned with great pleasure to the point where she came again on the spot. Wakko humped his sister as he pumped load after load of his seed into her. They both moaned and called one another's names as their climaxes slowly subsided.

They both collapsed onto the floor as they basked in their afterglow. Breathing heavily they stayed silent and enjoyed the moment.

"You're still inside me, ya know," Dot said breaking the silence.

"I know but it feels faboo," Wakko said with a euphoric grin.

"Well you're gonna have to take it out eventually, Yakko is going to come home in the morning,"

"I know..."

They stayed in silence for a little while longer.

"Dot?"

"Yes Wakko?"

"Is it bad that I kinda wish Yakko wouldn't come home for a while longer so we could be alone together?"

"No Wakko, it's not."

"What makes you say that?"

"Because I feel the same way."

They had another moment of silence.

"We will do this again, won't we?" Wakko asked.

"Of course we will," replied Dot.

"What about Yakko?"

"We'll just have to do it in secret."

"How are we gonna do that?"

"We'll figure it out."

"And if we don't?"

"Then who knows? Maybe he'll end up catching me in front of the TV, watching porn, touching myself and already covered in my own cum."
