Wish She were straddling my face while He was pounding Her making me lick Them both and then making me lick the Cum from Her Pussy and His Cock being sure to degrade me the entire time.
It's great to fuck your MIL, especially when you cum in her pussy and she feel you pumping your seed deep into her willing mature body where you both want it and it belongs. Just don't let your wife catch you. But, then if she does catch you, you can always take up with your MIL.
