Like the instagram a lot ! It has a good design and feeling to it.
Regarding the PornHub video ; I can only speak for me, but there is so much free porn everywhere that a public video with a dildo without context won't cut it for me. Personally, and I'm sure lots of guys are the same, I can only enjoy it if I have a special connection with the performers (like, I know you, and you don't usually do it ; but for me and a few others, you're taking this dildo out and vocalizing how much a trophy bimbo girl you want to be).
Or yeah, you have big fake boobs and everything rolls smoothly ^^.
PS : hope you don't mind the direct tone, there's honest feedback here ^^.
