You've been obsessed with your big sister for a long time and you're jealous that she's sneaking out to see her boyfriend. She's annoyed when you walk in her room unannounced while she's changing. You call her a slut and threaten to tell mom and dad if she doesn't have sex with you. "I'll show you what a real slut is," she says and agrees to fuck you without a condom. Lots of dirty talk with squirting dildo fuck and creampie. You accidentally cum inside her and she is horrified. "You weren't supposed to cum in me!" she says.
