>>10807This. I wouldn't pay for a feeding session if there was no sex involved.
Which begs the question: I have no doubt that fat prostitutes exist, but I have serious doubt that many of them are attractive or heavy enough to be worth it.
However, I also doubt there are many prostitutes who wouldn't accept money to be fed. It's just a matter of how much you'd have to pay - and I doubt it'd be too extortionate, considering how incredibly tame feeding is compared to things guys usually/sterotypically want to pay extra for (e.g. shit, piss, stepping on his balls in high heels, you get the picture)
TL;DR: If you're hellbent on paying to feed & fuck a girl, your best bet is paying a regular (i.e. thin) hooker extra to feed her, unless your standards are really low
