Yes, I know. This was inevitable. But! I have a background story for how/why she's into diapers too. Here it is:


She was attracted to diapers ever since she was potty-trained. She knew full fell that she was no longer a foal, but still she always imagined she'd wear them again, ever since she was a little filly. But she was too afraid to ask her parents, or to fake wetting herself as an excuse of being put back in them. The only times she ever got to wear some was after visits to distant relatives - while they had foals of their own. She would sneak a baby diaper or two in her bag, then put them on when she had some time alone after school.

Until one fateful day, she decided she would take a risk - and skipped her last class to go to a pharmacy. She'd been saving up money just for this special occasion. She got one bag of diapers designed for bedwetting colts (she couldn't get the fillies' ones, that would've made her suspicious), rushed home, and put one on right away. She was in such bliss, she couldn't help but shed a few tears.

She eventually spent the whole afternoon in them, putting on the next right after taking off the other, and she enjoyed every second of it. Then when her mother arrived home, she quickly hid it all. She wished she could sleep in them, but she was worried her mom would find out in the morning.

Then, weeks later, her friend Vector asked her out for a sleepover - a perfect chance to put one of her last diapers on for bedtime! Of course she would have to be careful and sneaky, but, she reasoned with herself, even if she was found out, she could just tell them she wets the bed sometimes and didn't wanna risk ruin Vector's bed. She'd also make them promise not to tell anyone. But the best case would be not being found out.
