You bought them at a pet store but you didn't know that they can transform into human girls.

they are trick or treaters and they arrived at your house. they are wearing bunny costumes

She is your wife

You are on your private jet and your flight attendant hands you a note saying to meet you in the bathroom

You are robbing her. she has 2 daughters and no husband

You are a big parasite and you need a host to live

you are in the deep sea

You are a powerful lion male but your hungry so you take her to your den
