You better be sure about what you want before you go spilling your guts to your wife, once she gets a taste for fucking your ass and getting fucked by superior cocks there'll be no going back. Not that you'll want to go back of course... but once you open the floodgates you might find your wife has a dark side you never even knew existed.
Stroke thirty times and imagine how it will feel to be pounded from behind by your wife while you choke on her lover's thick black cock.
