Public Nudity/Ask him to drop his towel and join you downstairs for a naked breakfast
"Damn straight!" You declare loudly, then stand erect and give your brother a military-style salute.
Kevin follows your lead and returns the salute, but because the towel was pretty tight on him, it came untucked as he stood upright, causing it to unfurl. You're able to catch a quick glimpse of his erect penis before he abandons the salute and grabs the towel before it has a chance to fall to the floor. You giggle as he scrambles to re-secure the towel around his waist. "What's so funny?" he asks you, slightly embarassed.
"Nothing, I..." you search for a lie that won't hurt his feelings. You certainly don't want him to think you were mocking his dick. In reality, you were just laughing because you had been waiting so long to finally see his hard cock. When you were younger, you had tried repeatedly to "accidentally" catch a glimpse of your older brother naked, but everytime you tried, his penis had been flaccid. If you had known that all you had to do to get him erect was trap him in the bathroom and present him with your young, naked body, then you would have done this years ago! "I've just never seen you naked before. I mean, not really naked."
"Well, I've never seen you naked before either, Claire. So maybe we should get dressed."
"No, I'm having a naked day, remember?"
"Right, yes, I know. You just said that", he stammers as he continues to look your naked body up and down. "I just mean that maybe I should go get dressed now."
As he turns and heads towards the door, you run over to the doorway and block his path with your tiny nude body. "No, I mean I want to see you naked. Like... really naked." You're a little ashamed to admit this to him, but you've decided that honesty is the best policy.
"I dunno, Claire. That seems kind of... weird."
"But it's my birthday!" So much for honesty. Now you're determined to use every tool at your disposal to see him naked. "You said you want to give me something special."
"Yeah, I meant like a card or something at the mall. Surely there must be something you want there?"
"Nuh huh. The only thing I want is under your towel!" You didn't mean for that to sound as sexual as it sounded, but there's no taking it back now. He just stands there for a moment, looking at your naked little body, while he ponders the possibilities. Is he actually thinking what I'm thinking? You think loudly to yourself, Gimme your dick! Gimme your dick! Gimme your dick!
"Shit, Claire," he says as he looks out the door behind you. "How long did you say Mom & Dad are going to be gone?"
"They're going to be gone all day!" You shout with glee. There's only one reason you can think of why he would ask you that question. He is thinking what you're thinking!
"Well... I tell you what, little sis. If you promise to behave and not tell anyone about this--"
"I promise!" You say excitedly.
"Okay, well, since it is your birthday, I guess I'd be willing to join you for breakfast downstairs."
"In the nude?!?"
"If that's what you really want."
What you really want is for your brother to turn you around and shove his cock up your tight virgin ass! But, one step at a time. "I do!"
Kevin sighs loudly, then looks down at you. You're afraid he's about to laugh at you for being such a weirdo freak. But instead, he just silently reaches down to his towel and untucks it, intentionally this time. As the towel falls to the floor, his semi-erect dick springs up and you swear you could hear a "boing" sound effect. This causes a massive grin to appear on your face as you stare down your older brother's cock. It's so much bigger than you imagined! And it's only a couple of feet away from your naked body.
As you stand there, it occurs to you that you are finally both completely naked together in the same room! Your childhood fantasy has come true! Well, at least the first part of it has. You're compelled to continue the fantasy and get down on your knees and suck your brother's cock right there in the bathroom, but you know that's not part of the agreement. Yet.
"So, did you say something about pancakes?" He asks, as you just stare at his dick, hypnotized by its glory.
After a few seconds, you realize that he just asked you a question. You manage to pick your jaw up off the floor and say "What?"
"Pancakes. Let's go eat 'em!"
You'd rather eat his sausage, but pancakes will have to do. For now.
He takes a few steps closer to you, and you continue to stare at his cock. It's getting stiffer by the second! As he approaches, for a moment you think Is he going to fuck me now? Right here? But then he walks right past you, his dick passing within inches of your teenage pussy. By the time you even realize what's happening, he's already past you and out the bathroom door. You turn around just in time to see his sexy ass walking down the hallway and over to the stairs. "Are you coming?" he says as he heads downstairs.
"Not yet" you say quietly, but then reach down to touch your teen twat and realize that you are a little wet. By now, he's already out of sight. You consider just standing there and masturbating to the thought of what just happened there. Or maybe you should dry yourself off and join him downstairs. If you really wanted to mess with his head, maybe you should put on some sexy clothes before going downstairs, just to see his reaction.
