Pure Fantasy

My wife and I (early 40s, kids) barely drink and rarely have time for a proper "date night," but when we do, we visit our local dive -- and it really is a dive, not some hipster facsimile. It's always the same bartender, a guy who's about ten years younger. One night, when she was a bit tipsy, she admitted she'd fantasized about having him in her mouth while I filled her from behind. I'd known she had a two-cock fantasy since before we got married, but she'd never attached the fantasy to an actual person. (She'd only admitted to girl crushes/lusts.) Being a broad minded (and somewhat heteroflexible) 21st century man, I said I was open to it. She quickly filed it under "pure fantasy." But I wonder...
