Shoesession

Partner really wants me to yellow up her knee high converse. Been cumming on them for a couple months but very little progress. Any tips?

...

Guess they disappeared into the wild blue Yellonder.

Test

Figured out how to get pics working I think

Pissing them helps

Definitely hit the laces a bunch let it soak in

These are the knee high converse I've been working on. Trying to get the rubber more yellow. Getting a bit on the toe

If you meant cumstain-yellow, that's one thing and can't particularly speed it up...if you mean the appearance of ageing that all shoe rubber goes through, consider storing in better (meaning, worse) conditions? Damp, humid, hot, sun exposure, etc. Though of course this weakens the shoe and that's already a hard-to-find model. Also the usual risks of mildew and such, like any mistreated clothes.

Roughing up the rubber to simulate wear also helps a little, e.g. with (fine) sandpaper. Stuff sticks better, oxidization happens faster.
