My Girlfriends Step-Sister

You have called round to your girlfriends house but her older step-sister answers the door and tells you “she’s out but you are welcome to come and wait” while she gets ready to go out. You sit down in the living room and notice her step-sister in a small silk robe she sits across from you and chats for a while when her breast falls out of her robe your eyes light up as she looks at you with a grin. She then starts to question you about your relationship with her little step-sister she’s wondering if she’s woman enough for you and before you no it she has her lips around your cock.
