After a little searching, you find a gorgeous blood-red Chinese dress. You're weirdly drawn to it, the soft silk, the pretty pattern, the shape that allows a lot of freedom to your legs (including to flash them at the sides)… yeah, you've gotta try this on!
You take a look around, and seeing no one else you pick it up and take it back to your house. Once safely in your room you undress hastily, stripping to your underwear, stepping into the dress, pulling it on and fastening it along your collar. You blush a bit as you realize it really suits you, despite how awkwardly it fits on you given you're a boy.
But at the same time, boy is the fabric comfy! And surprisingly, it isn't too small for you despite being a bit smaller than your usual clothes size. Not to get too cocky, but you think you'll look pretty amazing in this dress.
Smiling shyly, you flash a leg and giggle at someone imagining you being sexy in this thing. But when you brush your hair down a little, you realize, you do look kinda feminine wearing this. Obviously there is the problem that you're not Chinese, but hopefully your sister and her friends won't notice. And if they do, you could always just say it's from a relative or something and see if everyone buys it.
Then you notice the other problem- you're tenting the front of the qipao with your dick. Good job. Well, that's one positive- you've found something weird to get off to. As long as no one finds it, this dress could be a new toy for you. You can't imagine how amazing it must feel to rub the red silk along your shaft and cum on it. It feels nice enough on your skin, and you figure that's nothing to how good it would feel to get off against.
Figuring you'd better not ruin the qipao with your cum- at least, not before the sleepover- you unfasten it and move to take it off. Suddenly you realize, how did you know it was called a qipao?
"You didn't realize that, I just know it," a voice says in your head. It's in Chinese, but somehow you understand it perfectly. You freeze. What was that?
