I also was looking for it for a while way before you but the exact gif you’re talking about was made from the 08/17 stream. Idk which of the two videos in the download links on the thread, (pretty sure it’s the first one) but I know it starts at around 1:19:00 when she starts swallowing it, and also a longer session of sucking it a while before that. But the cheek-sucking thing is around that time
