You have always had a crush on your step-sister. She is older, hotter and you love how badly she treats you.
She comes to you with a "confession" that she also had a crush on you forever and would nothing more than to do it with you while your rents are out of town. She barely makes it through the confession before she starts laughing hysterically.
She has played a cruel joke on you, but you actually thought she was serious! How pathetic. She would never do it with you. You are gross and disgusting, but she does plan on doing it with someone tonight,
that guy who picks on you maybe?
How embarrassing for you to be cucked by your school bully! Don't worry I'm sure you'll at least get to hear the sounds of her orgasming on his cock.
