Stepbrother tricks stepsister in guessing game

I came back from college and I was doing the usual, when my big stepbrother came into the room and asked me if I'm up for a guessing game. Since I'm a fan of any type of game, I was so excited to do this, especially when he promised that will give me his car keys if I win. So we started. He first blindfolded me with a stocking and that was pretty weird but he said that it is part of the game and I have to do it so he can be sure that I won't be cheating. He also tied my hands. Then he pulled off my panties and I got pretty ashamed and stupefied but he kept saying to relax and then put a Lovense Lush toy in my pussy to punish me if I get answers wrong. At that moment, I was pretty sure that the guessing game it is no longer a usual one but more sexual. We started the game. He put various things in my mouth, starting from a cucumber, then a dildo, an anal wand to a wooden spoon. I got all answers wrong and he punished me by starting vibrations on lush.
