When it comes to 'big girl' pussy... there are 2 kinds of guys.
Those that love it, and those that lie about it!
I'm sure there are men who would love to take her out and show her off as their prize, but it's a 2-edged sword.
Often, these are the same men that have tendencies to abuse BBWs, and/or the ones that want to pimp them out.
I have a BBW GF that tends to get abused in some form or another when fucking other men. Nipple pinching/pulling/stretching to the point of pain, grabbing her fat pussy lips and stretching them out, getting spanked while being fucked from behind, working multiple fingers in her pussy AND ass. You get the idea.
As long as it's safe and consensual, I don't mind, but it's got on the borderline of out of control a time or 2. By the same guy, FWIW.
If that's what you're looking for her to do, more power to ya! Just be careful what you may wish for.
