A/N: I do not own "Good Luck Charlie" or any of the characters involved in this story. They belong to the Disney Company and always will I'm sure.

It was just another ordinary Saturday night at the Duncan family residence. Charlie and Toby were sleeping and the rest of the family was having their weekly family game night. The game tonight was Charades and the teams were Bob, Gabe and Teddy facing Amy, PJ, and Teddy's boyfriend Spencer. It was Teddy's turn to act out the clue and unfortunately for her the clue she drew was stripper. She was now in quite the predicament. How was she going to act out being a stripper to her father and brother without doing anything provocative or wrong? After stalling for a few minutes, Spencer and PJ decide to look at the clue Teddy has and begin giggling. After she begs the other team to let her switch, the two teenage boys deny her request. She could understand her boyfriend wanting to see her act like this, but to know her older brother was excited to see that should have disgusted her, but for some reason it just turned her on.

She didn't want to ruin the game so she began dancing seductively and went over to the other team and grinded on Spencer AND her oldest brother until her younger brother squeaked out the answer and ran to the bathroom. The rest of the night went on kind of awkwardly as Gabe never returned. When there was a break in the game, Teddy went to look for her little brother, afraid that she may have been the cause of his discomfort.

She looked for him through the halls and upstairs and in the basement, but finally gave up. As she went to go to her bedroom before heading back to the game she heard a faint sound coming from the bathroom. As she got closer to the bathroom, the noise got louder and she could recognize it as Gabe's voice and it sounded like moans of pleasure coming from him. As a curious girl might, Teddy carefully checked the restroom and realized before she looked that her brother was pleasuring himself. The sound of his moans was turning Teddy on and she had no idea why. It made her wet and drove her wild. Unfortunately for her, though, the torture wasn't over, because as she finally snapped out of her daze and began to leave before the temptation to look became too much she heard the word that sent her to the point of no return. At that moment she heard Gabe moan softly, but just loud enough for her to hear "Teddy!" At this, Teddy knew that her actions earlier that night had driven her brother just as crazy as his current actions were driving her. She quickly and decisively made her plan and began to enact it. First, Teddy had to make sure there would be no interruptions. So she convinced her parents to go out for the night and have a "night alone", then convinced her brother to go with Spencer and gave Spencer a quick kiss goodbye.

As she had hoped, Gabe had no idea what was going on downstairs and was still not quite finished with his task, but seemed to be getting closer, because his moans and whimpers were slightly louder. She waited for her cue, and as if he knew Gabe moaned his sister's name again, but this time there was more. Teddy heard her little brother say "Oh yeah Teddy! Suck my cock! Mmmm yeah Teddy, suck your little brother dry!" Teddy waited a little longer and heard a desperate and slightly louder cry of "Teddy!" Then she sprang into action. She went into the bathroom pretending to be concerned for him. "Gabe? Are you… Oh Gabe! Ew" Gabe quickly cleaned himself up and pulled his pants up embarrassed and ran out of the room crying. Teddy did not mean for this to happen, so she made sure she looked sexy in her red shorts and low cut tank top and went to "check on" Gabe. She knocked on his door and opened it, just to find him in the same position he was in while in the restroom. He began crying again and vehemently apologized to his sister. "I am so sorry Teddy. I just... I am a guy… You shouldn't have barged in the bathroom… or in here. Please don't look at me weird." Teddy just looked at her brother and said "It's okay Gabe. I just have one question" "What's that?" her little brother inquired. "Why were you moaning my name little brother?"

Gabe was shocked that she knew and was now even more embarrassed. He started stammering and stuttering and she knew this was her time to strike. She slowly got on her brother's bed and crawled up next to him and whispered huskily and lustfully into his ear "Do you want your big sister to take your dick into her mouth and suck on it until you fill my throat with your delicious hot cum Gabe? Do you want to stick that big snake of yours into my hot sopping wet virgin pussy and make me moan your name? Do you want to use that nice big cock of yours to stretch out and fuck my tight little asshole until I scream? Do you want to fuck the shit out of your big sister in every hole and make me your personal bitch and slave?" Shocked at his sister's lustful words Gabe just stood there in what seemed to be a paralyzed state.

Teddy took this as a yes and moved closer to her brother and began kissing him passionately. At first, Gabe was unable to move, but eventually he began to kiss back and even granted his sister's tongue entrance into his mouth. Teddy was pleased with her brother's kissing skills and would have never guessed that this was his first kiss. Teddy felt the bulge in Gabe's pants against her shorts and they quickly discarded all of their clothes and fell to the bed fully naked. Teddy saw Gabe's eleven inch cock and her mind lost all control. Her urges to touch and taste the cock were soon met as she grabbed the dick and began to stroke it. Gabe closed his eyes in pure ecstasy as his sister decided not to tease or play with him and began slowly sucking her first cock. Gabe had never felt anything like this before and before Teddy could even get down to seven inches of his cock in her mouth he came without warning down her throat. Teddy smiled up at her little brother and swallowed every drop of his cum. She then lustfully said "Mmmmmmm. I love the taste of my sexy little brother's cum. I want to taste some more." And then, just like that, Teddy is down with her mouth on Gabe's dick again, making it hard quickly. She begins sucking her little brother and using her tongue to lick up and down the shaft as the head of his dick slightly prods against her throat and, when she can, she lets her tongue lick out and touch his balls, making him shudder. Finally, Gabe came once again, as Teddy was rubbing his balls with her hand as she sucked his dick dry. Just as the forbidden lovers were going to go deeper into their sin, they heard the front door open and shut and footsteps coming up the stairs…
