I'm looking into subsiding other people's commissions IF they contain some content I like, again. I think last time I was outright going to pay for commissions..
STARTING August if you approach me early in the month with a commission idea involving couples (FM) with a much smaller individual getting caught between their love making and the smaller individual more or less drowning in cum in the lady's vagina or stomach, then I may subsidize some portion of that commission.

Months where I will usually have nothing special planned(birthdays being a consistent special thing) with my funds and thus could potentially contribute are: January, March, April, June, August, October, and November, so if you approach me in these months early on it'll be something I have a reasonable chance of doing. it. (ps: excluding a handful of prolific enough commissioners already commissioning what I like, I should probably find some sort of trustworthy escrow for this..)

Artists: I'd be willing to contribute a bit for YCH templates to be made for these subjects, so your full payment come from people paying to fill in their characters for the situation, and my payment is just for the situation to be sketched without any characters filled into the slots... if that makes sense.

Everyone: Just to note, it'll be rare I contribute more than 50 USD, and as I'll probably end up deciding what I should subsidize is a percent up to that amount, don't necessarily expect that 50 USD is how much of your commission I cover.
