Lady Fyre: A mother's day to remember

It's Mother's Day, you dutifully color a card for your mom. You take it into her room to surprise her, but she's kinda naked, doing something strange when you walk in. She seems really embarrassed, covers herself up. But there's something buzzing under the covers. You reach for it, she slaps your hand away, but you want to see what it is. You hold it up, she snatches it from you. What is it? She explains that while you've probably never experienced it, it's important to have something called an "orgasm". She's been alone for a while, doesn't have a man to give her one, so she uses that buzzing thing to do it herself.
