I fucked my mother in Law M22 F50

Me and my wife visited her Family. After spending some hours together my wife and her father wanted to go to the shop. So her Mother and I stayed at their house alone. When they left she started to confess about their bad sex and that she needs a better partner in bed. I did not want to hear that firstly because i never had the idea of having sex with or even kiss her. So she asked about our sex and if i and her daughter are happy about our sex. Yes we are. After that she went to her room. She changed her clothes and is now wearing a sexy red dress only. I could see that she had No bra or panties. I wanted to resist but she tried to touch and i became horny so i started First to touch her leggings. One thing let to another and i fucked her in the living room. I dont regret it because she was awesome and deserved better.
