Lost giantess POV video — girl says “I learned some magic,” striped shirt, staged shrink

Looking for a specific giantess shrinking POV video I watched around 2021-2023 (probably on Spankbang, max 720p).

Scene starts with a brunette girl sitting right beside me (POV), casually talking. She stands up, walks away, then comes back and says something like “I learned some magic” (or “I learned a spell/magic trick”), does a chant/spell, and shrinks me in clear stages. Title has the word “magic” in it and probably “girlfriend” or “step-sister/step-sis”.

Key visual: Before the shrinking starts, there’s a part where I’m standing in front of her and I’m about her height or a bit taller. She’s wearing a horizontally striped blue-and-white shirt + short mini jeans/shorts. I’d recognize her instantly.

Not Ginary/Raquel, not Helly Manon/Winzlings, not Diane Chrystall, not Ludella Hahn. Any help finding the title or a re-upload would be amazing — been looking for years!
