Help with wedgies
 

I’m not sure if this is the right place to post this but I need some help. I recently got some small briefs in hopes that they would ride up my ass all day but the elastic is too thick and they stay put over my ass. There great for holding ice and messy food in my underwear but I want briefs that will be riding up constantly. Any way I can alter these briefs so they ride up my ass? Or tips when I’m underwear shopping next?

That's awesome!
Never thought of wedgies as being a fetish, but the Internet is such a fantastic place that anything goes!

Even if you aren't into wearing female underwear, there are some styles available that naturally do this like thongs.
