oh no doubt she will if he fucks her good and gives her lots of cum. The wives I've played with definitely love my girth, but they love most the amount of cum I have for them.
I'd recommend the Aria, Cosmo, or Planet Hollywood. These are generally "younger" hotels, meaning they generally attract a younger crowd. There's a couple nice bars in the Aria I've had luck in, too.
Knocking up someone else's wife is at the tippy top of my fantasy list. Unlikely it'll ever be realized, but I hold out hope lol until then I hope to read more about it happening
