You could easily get away with an eye or carnival mask, but a veil seems a poor choice given the content you're talking about.
I totally get not wanting your identity made public, but if that is a major concern this might be the wrong field. I might not have seen the sites you're considering however most would seem opposed to a masked model. It might be something you need to work up to so a mask is a good starting point.

Sounds cool, let us know when you join a site.
In the mean time since you are asking for donations you might want to post some pics or an intro video so we can see who we're supporting. An intro video also shows us the video quality we can expect to see.

Honestly I could see it both ways. As a gainer you might as well gain since you can't say when your next relationship will start or maybe it'll even draw her to you. But as a mutual gainer part of the draw is growing with someone so keeping your weight where it is means you can maximize the amount you gain together.
Personally I'd go ahead and gain, but I'm also not a mutual gainer.

Active gainer, but enjoys watching others gain as well.

Depends who i'm around, by myself or out with people who know my appetite i'll stuff myself, but i try to hold back around my more normal friends unless we go to a buffet or they decide to order big too.

Don't forget the awesome ness of having to rest your belly on the counter to get close enough to reach high shelves.

Its not surprising that a fetish built around getting fatter would gravitate toward a sedentary hobby like gaming. It encourages hours of sitting in one place and pairs well with snacking. I'd imagine we probably have a healthy community of readers too. Both give lots of hours of entertainment for a single fee so it also minimizes the blow to budgets that could be spent on more food

So as far as I know stuffing is the most sure fire way to get the look you're talking about. Maybe ab development could work but you need a layer of fat to keep it looking like a belly. It might work if you focus on exercises like crunches that increase muscle mass without much definition development, though I admit I'm completely outside my usual areas of knowledge here, you'll need to research to find the exercises you want.

Honestly I completely agree with you there. Couldn't really say why, maybe just the idea that you've gotten so big that they aren't bothering with styles anymore.

Awesome, thanks!
