Vincent, the frat boy with abs for days, is home for the weekend. Hello Siri3, his step-sister, watches him from her doorway, admiring his physique. She's been curious, been wanting to feel him, to taste him. She approaches, dressed in her mom's lingerie, a thrill running through her. He's her first, her forbidden fruit. She takes his hand, leads him to his room, and closes the door. "I'm not your mom," she says, undoing her bra, offering him her small, perky breasts. "I'm so much more."
