Since most of my followers are probably more interested in being the victim than in tying someone else up, I was thinking of something along the lines of this:

Person buys a discounted sketch commission as a 'before' picture, then for a week or two after the before picture is posted, anyone can toss me a few dollars to get points with which they can buy BDSM gear for the character. After that time is up, they get a second, 'after' picture with all the gear that everyone has bought them.

Items will cost different amounts based mostly on how many other options they conflict with. For instance, a straitjacket would be much more expensive than a ballgag, since it basically prevents any other arm gear and a lot of body gear.

Price would be something like 45-50$ for the victim, and something like 2 points for $5 (5 for $10, 15 for $25?), where any simple gear like ballgags or wrist cuffs or stockings would be 1-2 points, stuff like hobble skirts or armbinders would be 3-4 points, and something very restrictive like a bitchsuit would be 15 points or so.

Victims could also have opt-in body-mod or hardcore lists for people to buy from as well.

Would there be much interest in this, as a victim, or as bondage-gear-supplier?

EDIT: if this seems too expensive, I could also do a version where it's only the 'after' picture, so the gear prices would be probably half or less of the above prices.
