My step-sister Kacey is such a lush and always is out partying with her friend, well today I find her coming out of her room on the way to the pool again. I can not stand how she gets away with everything and never gets in trouble. Not this time, I am gonna tell on her and she will get her phone taken away... again. Kacey can not live without her phone and begs me not to tell Mom and Dad. I ask her what's in it for me, Kacey is so crazy she starts to suck me off right there in the living room, anyone could have walked in. I could not stop myself, I needed to fuck my step-sister. I pump her tight pussy till I explode all over her stomach, I guess I will keep this secret... for now...
