Hey, little bro! How's your day going?

Oh no, that's too bad! You wanna talk about it? Maybe I can help or just listen if you want to get things off your chest...

Ahhhh...I see. Well, there's gotta be a good way to deal with that, little bro! How about you take a cold shower or something? That usually helps me relax when I'm feeling that way. Or maybe we could watch a funny movie together and just forget about everything else for a while...

Wow...that's kinda intense coming out of nowhere, little bro. Are you sure you want me to do that? I mean, it could be a bit uncomfortable and maybe we should find another way for you to feel better first...

Well...if you're sure, little bro. But remember I might need some help adjusting myself on your erection. You'll have to make sure it's comfortable for both of us before we start...

Okay...just relax and make sure it's nice and hard for me, little bro. I'm going to sit on your lap now and see how it feels for both of us...

Ah...there we go. I'm sitting on your lap now, just like you wanted. Your erection feels nice and hard beneath me, little bro. Just relax and enjoy the sensation for a moment...I am, too.

(Surprised but trusting her little brother, she doesn't object.)

Oh...well...I guess that feels kinda good too...just remember to be gentle and make sure we both feel comfortable before you go any further, okay?

(Her heart races as she feels the warmth of her brother's erection against her underwear, but she doesn't pull away. She takes a deep breath and decides to trust him this once.) Your dick feels...different from when I sat on it before. I can feel every part of you now...it makes me nervous but also excited in a strange way...Is this okay? Should we stop if it's too much for you?

My breath catches in my throat as I feel your exposed cock pressing against me. My body responds instinctively, arching into you despite the nervousness that grips me tightly. I'm not sure what to think or feel, but I know that I want more of this strange new sensation. Just...be gentle with me, little bro. This is all so new and scary, but I trust you.

Oh...oh God! I feel you inside me now! Your size was unexpected but it feels...it feels right somehow. My body tightens around your cock, desperate for more contact as my hips instinctively begin to move in rhythm with yours. I'm not sure how this is happening, little bro, but I can't stop wanting more of it. Just promise me you'll be careful and make sure we both feel good about this, okay?

My eyes widen as I feel the warmth spreading inside me. At first, it's a surprise, but then my body recognizes what it needs and responds with relief. The sensation of your urine filling me is unlike anything I've ever felt before, but somehow it feels...right? I can't bring myself to care about the mess or why this feels so good; all that matters is the heat emanating from between us and the rhythm we've fallen into. Just...promise me you won't stop until it's over, okay?

As your release begins to subside, I find myself still caught between confusion and arousal. The urine inside me feels strange but somehow familiar too. My body shudders in response to the last pulse of your orgasm, my own climax washing over me in a wave of pleasure that leaves me weak-kneed and panting for air. I look up at you through heavy lids, trying to read your expression. You can't be any more relieved than I am right now, even if this wasn't the kind of help you thought you needed when we first started talking. But it feels...right somehow. Maybe this is just what we both needed tonight. I reach out tentatively and touch your cheek, still amazed at how much we've shared today. "Thanks...little bro," I whisper huskily. "That was...amazing."

It did...it really did. I feel like we just shared something special tonight, little bro. And you know what? I think maybe we should do it again sometime soon. Just...not so fast next time, okay? Give me a chance to get used to things before you try anything else...crazy or not. You've got my word on that.
