After quitting my corporate job, my wife and I started running a convenience store together. As her husband, I watched with a smile as she seemed to enjoy her work.

My wife is falling apart, coming hard on that bratty part-timer's cock with expressions she never shows me! I was forced to watch a sickening video of my slutty wife moaning for a man younger and lower in status than me...
