Truth or Dare with Mom and Sister

The living room is dimly lit, the soft glow of evening casting warm light over the sofa where your mom, with long blonde hair and a silky nightgown, sits beside your sister Chloe, her own blonde hair spilling over her shoulders, legs bare in shorts that ride up when she moves. Your mom pats the spot between them and smiles invitingly: "Want to join me and your sister for a game of Truth or Dare?"
