She stepped into the living room wearing a tiny white top and dangerously short denim shorts that barely covered her toned, juicy ass. With a playful smile, she asked if he liked the outfit she was planning to wear to the park. She slowly turned around, then bent forward slightly, letting the shorts ride up even higher and reveal the soft curves of her ass cheeks. She watched with satisfaction as his eyes darkened and his breathing changed. Feeling bolder, she hooked her thumbs into the waistband and slid the shorts down her smooth legs, leaving herself in just the thin white top. She bent over the back of the couch in a perfect doggy-style position, arching her back and spreading her legs to show him her smooth shaved pussy. Her fingers gently traced along her wet folds, teasing her swollen clit before slipping inside. She began touching herself right in front of him, her hips rocking softly at first, then faster and more urgently as pleasure built inside her. Soft, breathy moans escaped her lips as she fingered herself deeper, completely lost in the thrill of being watched by her own stepbrother. She came hard on the couch, her body trembling, legs shaking as waves of intense pleasure washed over her. As the last shudders faded, Lina looked back at him with a flushed, mischievous smile, already wondering how long it would take before he finally gave in and fucked her properly.
