I do have an anthro spider, here he is:

Perhaps he's what you're looking for?

Close, but would you give permission? How is his webbing? Would you be willing to get a joint commission?

I would definitely give permission. He's a very good webber who tends to wrap his victims up in various ways, he always prefers males. I have an older pic of him with a wrapped victim (with breathplay):

As for a joint commission, it'd depend on how much it cost. But it could be fun!
I am also an artist (I did those two pics) and I'm open for commissions as well if you like my style.

Hmm, definitly consider it! Though, it is between picking another commissioner, or you X3 I am willing to get a $10-15 commission from someone and split the cost to make it easier.

I could easily pay half of $10-$15.

Ok! Hmm, who to commission...

And note me for details!
