[B4T] Grown With A Secret

NSFWFem4Masc

• Plot 

For years and years, we've grown together as a tightly knit siblings. You were the usual doting big brother who looked out for me either each passing days in our lives, I love you to death, you're my ride and die, my bestfriend. You protected me, a shoulder to lean onto when I feel bummed, you knew so well that I like boys since and you never ever cussed me about it. You were in denial at first, but it didn't take long for you to accept me for what I am sexuality wise.

But all these years you've been so oblivious about a secret that even our parents didn't even dare telling you at all. Like my body is a full on boy, nicely smooth slender body, a cute twink if I may say, so anyone even you can't even think that there's something suspicious about my body and you didn't even notice it at all when I'm on your lap, when we wrestle play and all that. Even back when our parents did an ultrasound of me when mom was pregnant, it was immediately thought that I am a boy until I was born. They both knew you were so excited to have a little brother but then again you were so oblivious about what I really am.

Today was a normal day perse, but not for me. You were out to have your usual gym session since you love keeping yourself in shape. But since I've grown enough to feel so much changes in my body, most of it is felt in between my legs, and I can't help but let my hand crawl in between my legs to ease all that I feel. Having myself laid back on my bed as I let my finger do its magic in helping myself out, thinking I'm alone, I let my sheets uncover my body the more touched myself and little did I know you came home earlier than you're supposed to, only for you to see something that you're so clueless about. Your little brother has a wet little cunt.

What would you do while you're stunned by your discovery as you peered into the little gap of my door? Now that you knew you little brother has been a cute cuntboy after all these years. And here you are seeing me trying my best to pleasure myself since I can no longer resist these sexual urges that's been building up in my body.

What would you do big brother? Will you try not to say  a word about it until I speak up? Will you barge in and confront me for keeping it a secret it to you? Will your body betray you and help your little brother out in since I'm struggling to pleasure myself on my own from how inexperienced I am? What would it be big brother?

So yeah that's basically the idea that I have and of course the I know being a cuntboy is a very unusual choice for a character in this sub and I'm just pretty much curious to play it out. But if you're not into the idea, I'd be open to brainstorm an idea that both of us can enjoy that is away from my initial idea. Of course characters in this play will be 18+. If you reached this point of my post, might as well say "Cherry" just so I'm aware that you really read through this post. Hopefully we can play this out and have our moment.
