In the glass-walled penthouse, Hello Siri3 and Vincent Vega, step-siblings, find themselves alone, the city sprawling beneath them. Their eyes meet, the air thick with unspoken longing. Siri3 bites her lip, her gaze lingering on Vincent's bulge. Vincent, noticing, smirks and begins to stroke himself, Siri3's eyes widening with desire. She slowly unbuttons her blouse, revealing her lacy bra, as Vincent frees his throbbing cock. They lock eyes, the city lights reflecting in their dilated pupils, as they give in to their forbidden lust.
