Crossing the Threshold

David positions himself on the bed alongside the lying Susan, his hands resting lightly on her hips. He gives her a moment to brace herself, then delivers a light, controlled tap to her bare vulva. Susan gasps, her body jerking in response. The sensation was sharp, a blend of pain and pleasure that sent a shockwave through her.

David's voice is soothing as he speaks, "How do you feel?"

Susan takes a moment to catch her breath, her mind reeling from the intensity of the sensation. "It... it feels good," she admits, her voice shaky but filled with newfound confidence.

David continues, each strike carefully measured, each one harder than the one before, each pause filled with whispered words of encouragement and praise. Susan's body responds to every touch, her skin tingling, her core tightening with each impact. She feels a rush of emotions – humiliation, arousal, and an overwhelming sense of release.

Her vulva is bright red and visibly dripping wet. Her breath comes in ragged rasps, her face deeply flushed. Involuntarily, her hands move to her breast, freeing her boobs from the confinement of her lacy bra, massaging them, kneading and twisting her swollen, strawberry-colored nipples.

As the session progresses, the lines between pain and pleasure blur, creating a heady mix of sensations that leave Susan in a state of blissful surrender. She feels alive, elevated, and respected, despite the humiliating strikes to her most private area.

Finally, she can't hold back anymore. Her body arches, she cries hoarsely. A spray of clear liquid gushes from her pussy and drenches the sheets.

After she collapses on the bed, David gently covers her with a blanket.

"Thank you, Susan," he says softly. "You are amazing."

Susan smiles weakly, a feeling of contentment washing over her. "Thank you, David. For everything."

"Rest and recover, as long as you want," he assures her. "The room's booked until tomorrow morning."

The screen fades to black, and the video ends.

"Do you need help with that?" Cody asks, gesturing with his chin towards his sister's crotch.

Sarah realizes only now that she had unconsciously started to rub her own pussy, the front of her white-and-blue-striped panties being soaking wet. She blushes violently, but manages to cast him a cheeky grin.

"No, thank you, I can still help myself, especially with that," she retorts pertly.

She pushes her hand deep down the inside of her panties, making sure that her brother doesn't miss what she does.

Only then, she turns her back to him, blocking his view. Her fingers part her burning pussy lips, easily finding her swollen, longing clit. She rubs it gently, eliciting low moans.

Behind her, she hears Cody unzip his pants. The rustling of clothes indicates that he sheds them to the floor. Seconds later, he groans. The squishy sound of his hand working his member and his quickening breath are clear evidence of his doing.

She intensives her own caresses, pushing herself further and further.

Minutes later, Cody exhales a euphoric "Yes!", throwing his sister over the cliff, too.

Both of them slump back on the bed, satisfied and spent.
