"Come here Mo-chi, I have something to tell you."
Mokou sat on the table right across to her father (not the Dragon of Gensokyo, but still a Pimp Dragon); even though her face was calm her father could see the inner turmoil going through his daughter's eyes. Well he didn't blame her, he went through the exact same thing the day he married his wife.
"It´s OK Mo-chi, just calm down and breathe."
"I am calm dad, it just, well…"
"Whatever fear you have now just put them aside for the moment. Listen, the advice I'm going to give you will help you and it will most likely solve any problem you have when you get married."
The white haired woman sat up a litter straighter and she leaned over towards the anthropomorphic dragon, her red eyes focusing on him and giving him her complete attention. Satisfied, he continued.
"On my wedding night in our honeymoon suite, I called your mother over, took off my pant and handed them to her; I said 'Here, try these on.' She did and said, 'These are too big. I can't wear them.' I replied, 'Exactly…I wear the pants in this family and I always will.' Ever since that night we never had any problems."
"Hmm," said Mokou. Maybe she will try it on her soon-to-be wife: Kaguya.
So the wedding went smoothly and the place where the honeymoon would take place was beautiful: a five star hotel, with a penthouse and ocean view.
During the consummation night, Mokou took off her pants and handed them to Kaguya. "Here, try these on…" Kaguya was a little perplexed to try them on.
"I can't, these are too big…"
"Exactly," she said with a smug smile on her face. "I wear the pants in this family. I don't want you to forget that."
Then Kaguya took of her black lacy panties and handed them to her husband. "Here, try mine on."
She did and then said: "I can't get into your panties."
"Exactly and if you don't change that smart-ass attitude of yours, you never will."
And so that's how Mokou discover who wore the pants in the family.
