Latina 18yo Step-Daughter Helps Me Relax Pt2

My little 18 year old step-daughter Paris caught me off guard while her step-mom was out gardening and I was having a snack in the kitchen. She said she liked helping me relax like she did the other day, and then she grabs up on my dick! She's always been a bold, fearless girl but this is too much. She wants to help Step-Daddy again while Step-Mom is outside working. I tell her to get her ass into the bedroom. I walk in and she's completely naked with her big 18 year old tiddies out, and she wants to stroke my cock. It's too weird, I say no, but she insists on helping step-daddy by touching him. My always gets her way.
