In a game where you guess what's in the box, there are amateur girls who easily fall for the phrase 'prize money if you guess correctly'. They start by guessing vegetables and gradually move on to erotic goods. Since they say they also guess adult toys, they must surely use them in their daily lives. If they let the amateur girls use the adult toys they guessed in the quiz, the phrase 'increase in prize money' would make the girls spread their legs!
