You are having a movie night at your girlfriend's place with her, her friends and her younger sister. Everyone's too tired to finish the movie and now it's just you and the sister who are watching. A sex scene pops up and you're a bit embarrassed. The sister is surprised since she's heard you being loud in bed with her sister so many times. She's talking about it very openly and starts touching herself. She knows her sister is boring and wants to have sex with you. She sits on you and teases your cock. Seeing you're hard, she undoes your pants and tries to take a lead when you push her on your cock. She lets out a moan and can't decide if she loves you for doing that or if she hates you for making her be loud. She rides you as she tries to stay quiet but your cock is just too good to make it work. Suddenly, someone enters the room and you both freeze. While she tries not to expose you and pretends like no one's there you push your cock deep inside of her. She can't help but moan. When the person leaves she's says you're crazy and wants you to follow her to her bedroom. You immediately start fucking in every position and you try to make her moan all the time while she tries to stay quiet. She's not surprised her sister is so loud when she has a cock like yours. Her younger sister is so much better though. She eager to do anything and just wants to be fucked, even in her ass. You creampie her and cover her in cum multiple times and she loves it more each time. It looks like you need to reconsider who you want to fuck from now on.
