Jerking off with my step sister Ela Darling

Now that your parents married, you have to share a room with your step sister Ela when you go on vacation. She is displeased, but you are happy to watch her pretty ass go up the stairs of the bunk bed. Even though you thought you claimed the bottom bunk, she is now claiming it for herself. She knows that you want to jerk off to her and she is willing to help you to get off if you give her the bottom bed during your week at the vacation house. You agree to her terms of complete secrecy and you get your dick out and begin jerking off. Ela knows you like her ass and she shows it to you. Work your cock with your hand as if Ela had her pussy tightly wrapped around it. She pinches her nipples as she continues to tell you how to work yourself over. Her small tits turn you on so much! She wiggles out of her clothes and starts rubbing her pussy and clit hard as she tells you that you must cum for her. You cum for Ela and you realize that you got the better end of that negotiation!
