Stepdaughter sucks & fucks me

It felt so wrong and so good at the same time letting my 18 y.o. stepdaughter suck my cock right in our kitchen while my wife, her mom, was at work. Next day she asked me to return the favor by eating her out and another day or two later we fucked right on a living room rug. I love her mom and stuff, but that tight young pussy is just making me lose my mid and do all this kinky stuff to my stepdaughter she obviously wants me to do.
