Nene had brought Mackey to her family home for the holidays. Mostly because Mackey had never experienced a true Christmas. The problem was that her family was part Russian and all Christian, which meant that since Mackey had spent the night in the wrong room-- there was going to be a shotgun, or in her father's case-- revolver, wedding. Not that her father really minded, it was her Mom that would be the problem.
The young couple waved nervously to her parents.
Mrs. Romanova folded her arms. "Mackey, I'd like to talk to you."
Mackey gulped. "Ah, sure."
"How old are you?"
"I just turned sixteen." He blushed slightly remembering the birthday present Nene had given him, which was her virginity.
Mrs. Romanova frowned. "Thought so. We'll have to wait until your eighteen before we can have the wedding."
Nene blinked. "Why?"
"A stupid law that was passed back in the nineties and they haven't changed it."
Nene gulped. "Is there an age of consent?" She had found out during her stay in the US that many states had an age of consent, which was why the guy she liked kept pushing her away. She was jail bait then.
"Don't worry. That's twelve."
Nene tried to absorb that information. Twelve was old enough for a girl to decide to get pregnant but not old enough to marry the father, that did not make sense.
Mrs. Romanova peered closely at the couple. "Now, have you two been using protection?"
"Y-yes." Well there was that one time last week they had forgotten to bring any protection, but that shouldn't be too much of a problem. At least Nene hoped there wouldn't be a problem.
"Good. Can't have you two getting pregnant until you can marry the father."
"Right." Nene nervously laughed.
"S-sure." Mackey's mind was mostly fried. They had somehow dodge the wedding bullet, but really wished Nene's mom hadn't brought up the p-word.
The comments on marriage laws and age of consent are the current legal laws of Japan. A twelve year old can decide to have sex with a fifty year old guy, but she can't get married. The marriage one was changed during the mid-nineties. Before then, the age was twelve, which works many anime series like Ranma 1/2 which takes place before that law was passed.
With little information on Nene's family, this can work. However, it's a series that you have to stretch a few things to make it work. Try again.
