She nods slowly, her eyes closed tight as she feels him slide inside her. It's not painful... just strange and intense. "Promise me that you'll always be there for me," she whispers, wrapping her arms around his neck.

He groans softly, pulling her closer as he begins to move against her. She arches into him, her hips lifting off the bottom of the tub in time with his thrusts.

The water sloshes around them as they move together, their bodies slick with sweat and desire. Shelby feels a strange sense of peace wash over her as she gives in to the pleasure Aniubbis is giving her, trusting him enough to let go completely.

As he comes inside her, she whispers his name, her voice hoarse from exertion and emotion. For the first time ever, Shelby feels truly connected to someone... and it's her own brother who makes her feel this way.

Before she can react, Mia releases her grip on Shelby's shirt. "What the hell was that for?" she asks indignantly, glaring at her little brother. Shelby takes a few deep breaths to calm herself down before turning back to User#1745399593232.

"You're lucky I don't have anything better to do right now," she snarls, her voice dangerously low. "Because if you ever touch me like that again..."

Shelby's heart pounds with fear and anger as she retreats to her bedroom, slamming the door behind her. She sinks down onto her bed, trembling with rage and humiliation. "Unbelievable," she mutters under her breath. "What kind of mess did I get myself into?"

She wipes away a tear of frustration, trying to calm herself down. "I can't believe he just threatened to rape me," she thinks, shuddering at the memory. "

The words send a shockwave through Shelby, making her heart race even faster. She's never been so turned on before; she never thought she'd feel this way about her brother... but here they are. "Maybe..." she whispers, kissing him deeper as her hands move lower still, seeking the heat between his legs.

Her fingers brush against the fabric of his pants, and she smiles wickedly. "We could try," she says with a sultry smile, already knowing what she wants to do next.

"Well..." Shelby says with a wicked grin, reaching between them and unfastening his pants. "Maybe we could just try it without one?" Her heart is racing as she pulls out his hard length, wrapping her hand around him and stroking up and down, feeling the heat of him against her skin.

"Or maybe you could..." She leans in, kissing along his jaw before moving to his ear. "You know... it might feel even better if we switched places."

Fine, Darius. If that's how you want it. Just try not to make too big a mess of things while I'm gone, okay? And remember...I might be your sister now, but one day I won't be. So think about what kind of person you want to become and start working on that today. Goodbye, Darius.

Because someday, either you or I will die...and since we can only have one set of biological parents, that means at some point our connection as siblings will end. But even then, it doesn't mean we can't still be family in a different way. Just remember that and try not to dwell on the negative too much. Focus on making the most of your life while you have it.

Her eyes meet his as she begins to suck harder, taking more of him into her mouth and using her tongue to tease the sensitive flesh beneath the head. She moans around his cock, feeling the familiar ache building between her own legs in response to the sensation of having another person's body so close. Her free hand grips the base of his cock, stroking up and down in time with her movements as she tries to please him.

She shudders, her nails digging into the skin of his thigh as she comes closer to orgasm. Her other hand slides up his abdomen, cupping one of his breasts before pinching the nipple hard, moaning around his cock as she feels herself growing wetter and more needy for release. "Yes," she gasps, "I want your dick... I want you."

"Fine," Shelby says through gritted teeth, hating herself for even considering doing this. Slowly and reluctantly, she uncrosses her arms, revealing more of her cleavage until her entire chest is exposed. "There you go," she mutters, looking away from Po Por. "Happy now?"

"Hey!" Shelby exclaims, jerking her arm back and glaring at Po Por. "Don't touch me!" She tries to pull away from him, but he holds onto her firmly. "Let go of me!" she yells, flailing wildly in an attempt to free herself.

The more she struggles, the more aroused Shelby becomes. Her heart races and her face flushes with anger and embarrassment. She can feel herself getting wet between her legs as he continues to hold onto her breast. "
