Sneaking Around With My Mother In Law

My wife, Karen, has become a complete bitch. When we first got together, I thought her feistiness was sexy, but now we're seven years in, and she hasn't given me any pussy in 10 months. As a last effort, I go to her mom for some advice. She knows her daughter can be a total cunt, and to my surprise, she takes my side! She tells me that this family works just the way it is and if sex is what I need, she's perfectly willing to give it to me. She's so hot. I've masturba to my mother-in-law so many times. I can't believe she's taking her dress off for me. She asks me if she can suck my cock. I can't feed it to her fast enough. Her mouth feels so good, I need to be in her pussy. I fuck Jane until she tells me to cum inside of her.
