Your sister heard you sneaking another girl into your room last night, even though your parents had forbidden it... She mischeviously tells you that she'll be tattling on you to your folks, unless you give her what she wants... She's heard you fucking these girls and making them scream so many times now, and they always sound like they're having a great time... So, she's become curious. If you show her what you're doing to make these girls so loud in the bedroom, she won't tell your parents that you've been disobeying them yet again...
