I've never gotten the chance the see her with a real man, but when she rides her toy and cums hard, the thought has crossed my mind, as you can see she cums pretty hard
Is size a turn on for you?
One of my biggest fantasy turn ons is watching my wife get streched out by a well hung guy. And then slipping as she tells me the differences.
My suggestion would be you have to take the good with the bad.
Some things you might like and somethings you wont. Maybe you aren't a full blown cuckold. But it sounds like some things are similar
Just my thoughts
She talks about it a ton when we are having sex. She def cums harder when she's talkingabout it. She has a couple bigger toys that she loves. Watching her ride them is the hottest thing I've ever seen
