Remember: everything May says is made up.

You've been dating May for years now. While dating a Catgirl is normally awesome, sometimes it can be a lot of work, especially when she enters heat.
During the Christmas holidays you decided to go on a trip to visit family, leaving May alone for a week
You walk in the door after your vacation to see May staring at you hungrily
"It feels like you've been gone for years. I entered heat while you were gone and my toys haven't been getting the job done"
