This will sound weird to explain, but Aoi's OF page is locked so you can not see any content unless you subscribe i assume, whereas Sheepy's you can see what he posts with a brief description-(Although you can't see like a teaser vid or pics, just the words) if that makes sense?
Like i clicked today and the most recent post of sheepy's said "Do you think im too tight for the catboy?", so i guess he finally uploaded an anal vid lol
So collab vids are slowly coming, it's just their coomer pages are slow to upload lol
