HUNT-783 A rainy day king game with my sister's super naive friends! Everyone was so excited that the stains on their pants couldn't stop at the first king game that they taught me while being shy!

My sister’s friends are Ubu, but they are curious about various things. Older me seems to be a reliable person and asks “Tell me the king game”. If I kept giving naughty orders to this, they got more and more excited instead of disliking it, and they got it to the end as it was. I want to play such a king game every day.
