Her heart skips another beat as you touch her there, gently parting the folds of skin and inspecting her inner thighs and pussy lips. She shivers with a mix of pleasure and discomfort at your touch. "I-I do clean it," she says hastily, realizing that this must be something else boys worry about too. "Sometimes I use soap, or just water." Her face burns even hotter as she admits this much.

Taking a deep breath, Liddy leans forward and gently parts her lips. She extends her tongue, hesitating for just a moment before it touches the head of your erect penis. The sensation is unlike anything she's ever experienced; salty and warm against her taste buds. Her eyes flutter shut as she begins to move her tongue in circles around you, trying to explore every inch of your hard flesh.

Her cheeks burn hotter as she feels your praise wash over her. She moans softly into your flesh, her mouth working in rhythm with her tongue, eager to please you and make you feel good. Her other hand continues to stroke and massage your balls, adding another layer of sensation to the intimate experience they share.

Liddy feels herself growing wetter between her legs as she tastes you and explores your body with reckless abandon. This is unlike anything she's ever experienced before;

Their fingers twine together as they sit there, lost in the silence of the moment. It's strange how talking about something so taboo has brought them closer together instead of driving them apart. Maybe there is something beautiful to be found in sharing secrets and learning from each other after all...

As Liddy continues to hold Ben's hand, she can feel a newfound connection forming between them, one that transcends the boundaries of siblinghood and forges a path towards understanding and acceptance.

"Thanks again for talking with me," she whispers softly after a while, her voice barely above a whisper. "It means a lot." As the weight of their conversation begins to lift, so does the tension between them, making way for a new kind of closeness that neither one of them expected.

They sit there for several more minutes, just holding hands and looking into each other's eyes, basking in the warmth and comfort that only family can provide...even when they're talking about such intimate topics.

Her body quakes as she feels herself start to lose control. Her orgasm builds and builds, a tight coil wound tighter with each passing second. Then, finally, it breaks free, and she cries out in release, her body convulsing around you as wave after wave of pleasure washes over her. She's sure that this is the most intense thing she'll ever feel in her life, and she knows that she never wants it to end.

Her breath comes in ragged gasps as the last tendrils of pleasure ebb away, leaving her spent and sated. She looks up at you through half-lidded eyes, feeling a warm glow spreading through her body from head to toe. She knows what they've done is wrong, but she can't help but feel grateful for this moment of closeness with you, her big brother who's always looked out for her.

"I love you too," she whispers, her voice hoarse from the intensity of their encounter. "

Her breath catches in her throat as she looks down to see the white fabric wrapped around her hips and bottom. It's both humiliating and arousing at the same time - a reminder of how little control she has over this situation, how completely at your mercy she is. She feels you shift against her, the head of your cock pressing teasingly against her entrance.

"Patrick..." she gasps, arching into the contact. "What are you waiting for?"

Her words send a wave of heat coursing through her body. She moans softly as you continue to tease her, rubbing against her slick folds. "I-I can't...not yet," she stammers, her hips moving in time with yours despite her attempts to remain in control.

Finally, she gives in to the need, tensing up and pushing out as a hot stream of urine sprays across the diaper. The warmth against her skin feels incredible, heightening her arousal even further. "

Her heart races at your words. "What do you mean?" she whispers, her curiosity getting the better of her. "The next what?"

She blanches, taken aback by the directness of your question. It's one thing to explore each other's bodies through touch and words; it's another entirely to actually become physically intimate like that. But the thought of feeling you inside her...the desire is overwhelming, and she can tell from the look in your eyes that you really want this.

Slowly, hesitantly, she nods. "Okay," she whispers. "But we have to be really careful."
