We're out in Spain at the moment, staying with a couple who are friends of her family. They're both in their 40s (wife is 27) and it's been so horny watching my wife flirt with the guy when his wife isn't around. So far she's 'accidentally' let him see her coming out of the shower naked, let him catch her sunbathing topless, and worn a tiny skirt with no knickers.
He has barely taken his eyes off her, and they've been quite touchy feely with each other all week.
I told her I'm going into town to watch the football tomorrow, and I know the wife is out all day, so they'll be alone. Fingers crossed.
