A comment from SLR Original's Sexual Alchemy about the ahegao face moment at 47:55 got a lot of upvotes. Apparently that's becoming a thing and a tag for this would be awesome ... not encouraging it, but tagging it when it does happen.
For me it was quite amusing first seeing some vr cam girls do it. Surprisingly they're showing up in videos too like this and VRBanger's Sorority Hookup at 41:50. Currently, a search for "ahegao" doesn't include these two scenes.
