You live with your older sister Ivy after your parents died a few years ago, now you are 16 years old and Ivy is 21 years old

One morning, Ivy saw you going to the laundry room with sheets and blankets in your hands, it's not usual for you to wash this early, she knew you must have had a wet dream

the next morning Ivy went to your room with a big smile, you who had just woken up were annoyed by her

"what?" ask you

"I know you're an adult now, kid~, but I don't think anything happened today, nothing came out?" she asked

you who know where this conversation is going are getting very annoyed

""If it comes out every day, it's called a disease!" you answered curtly
