I'd like to add to my comment that while we are playing together and she getting fucked good by her bbc dildo I'll ask her if she wishes it was a real one she always says yes I think she'd fuck ever guy in the room at that point she's that into it
Your situation sounds like mine my wife is really into it while we are playing in bed even when she plays by herself with her favorite dildo but goes cold to it when I bring up her fucking a guy with a big cock
I found a new position to fuck my wife with her big dildo she loves to play on her belly and I crawl on top she gets soaking wet knowing it's coming she doesn't even need lube she takes all 10 inches easily and loves it
Video is her playing while I'm at work
