Your wife's si ster is every man's fantasy. Sexy, naughty and wild. Not like your prude, conservative wife. You can't help but wish sometimes you met her first. You come home one day to find her on the couch in a little black nightie, looking mischievous as ever. She taunts you with her sexy body, telling you she's noticed you oggling at her behind your wife's back. Before you know it she has you on your knees, letting you know what a dirty little slave you're gonna be for her. If you resist, she'll be sure to make your wife divorce you, and you'll never see her hot si ster again :)
