A Diapered Christmas

I’ve been dating my boyfriend, Matthew, for over a year now, and I really love him. He’s thoughtful, funny, everything I could ask for. But there’s just one problem in our relationship—his step-mother. It's obvious she doesn't want me dating her step-son by the way she treats me...and the way she treats me is like a little kidd. My boyfriend wants me to just go along with it and appease his step-mother…So I do because I love him and I tell myself it’s only a few times a year. But now Christmas is coming up and I’ll be joining him and his whole family for the first time... When we get there his step-mother already starts with her condescending tone and tells me I have to stay in Matthew's little step-sisters' room rather than with him. Then at dinner something really embarrassing happens. My boyfriend's step-mother makes me sit at the kids table because she says there's no room for me left at the adult table and unbeknownst to me someone had an accident in the chair I was told to sit in. Soon it soaks up into my jeans and I'm mortified to find my butt all wet. To make matters worse his step-mother makes me eat from a baby plate and drink from a sippy cup. Then when dinner is over she catches on that something's up with me and demands to know. She turns me around to see my wet butt and is convinced I peed myself. I'm ushered upstairs where Mrs.Taylor changes me into a pull up herself. Then she makes me wear one of her step-daughter's little pink nighties! She makes me go to bed at the same time as her girls and tells me I'm not allowed to get up because I might wake up Matthew's little step-sister. But later I'm laying in bed and realize how much I need to pee. SoI try to sneak out of the room to the bathroom, but his step-mother catches me in the hall and sends me back to bed. I resolve to pee in my pull up since I don't really have another choice. Mrs. Taylor scolds me in the morning for wetting myself... The next few nights I end up peeing my pull up but I don't understand why! I made sure I peed before bed so I wouldn't have to use the pull up again but it still happened anyways. Little did I know my boyfriend's step-mother had been sneaking in the room with a glass of warm water to make sure I peed myself like a baby... Christmas morning comes and his step-mother gives me a gift. I open it up and it's a big adult diaper and little pink pajamas. She makes me wear them and I spend Christmas filling up that big fat diaper.... (Original idea by TheYellowSafe)
