You'll rent the hotel room for them, of course. I imagine a cheap motel with thin walls. Your wife gets to choose her lover. Leave them a big jar of lube. Normally I'd say let the guy spit on his cock and go to it-- but you want the weekend to be a success.Hmm I’d love that. Maybe rent a hotel room for a weekend for my wife and another man. The idea being he has anal sex with her. As often as they can.
