Welp, this is why I say: "if you like it, stash it. And if you don't have enough room to stash it, then upload it somewhere else (redundancy is key)". Most porn websites are just a front for either xvideos or pornhub (the ones that actually host the videos), so if the video gets deleted from those sources you're usually out of luck (in your case, the actual source was
xvideos). Lucky for you, looking up the Chinese title ("直男教练被骗飞机/Straight male trainer cheated on plane") yields
this link with an alternative source ("直男教练被骗飞机身材超好超壮很猛/The straight male coach was cheated into the plane, super good, strong and fierce").
By the way, what do those Chinese titles actually mean (if you're from Hong Kong, I'm assuming you can translate them)? I have a feeling that "plane" (飞机) and "bird" (鸟) are slang words for "penis" (I'm asking because
I've my own Chinese crush).
