My Nympho Ass Eating Step-Sis

I recently caught my step-sister, Kuleana, masturbating to porn in her bedroom. Not only was she watching porn but she was watching some pretty freaky stuff, she had a video up of guy getting his ass licked. I tell Kuleana she is a freak and I am gonna tell her Step-Mom, Kuleana freaks out and begs me not to tell. I ask her what is she gonna do for me, I can not believe her reply... she offers to fuck me to keep me quiet. Of course, I jump on the offer to fuck my hot step-sister but I had no idea she was gonna eat my ass. Apparently my step-sister loves to eat ass and I let her eat my ass then pound her pussy.
