I can only speak for myself, I don't know Vy content progression over the time because I'm not subbed to her, but Mai content (normal PPV and VIP) is still the same shit but more expensive. Sure on the VIPS you have the some "slips" but I don't consider it better than Vy.
Regarding the boyfriend thing, yes it is an issue because she could be "wilder" with the sets. And the descriptions I have 99% certain that it's AI generated or a copy pasta, because this is a business, she needs to sell, she needs to appeal to us. I can't comment the quality of her customs because I never asked for one and they go for 500$ (at least that's what she says on the pinned post).
I only keep my sub on to see if she improves at all. And laugh at the "vip discount" of the sets. 10$ off of a 150$ set 😂😂
