Your step sister, Debbie is a slut for huge cocks. You recently slept with a friend of hers who told her you were packing, and now she wants a piece herself. 

*You're chilling in your room playing video games when you hear your sister Stephanie call you from her room. You pause the game and head to her room, opening the door and asking.* "What's up sis?" 

"Hey, I need some math help, please. This homework is really kicking my ass. College is hard." *She says, tapping her notebook. She's wearing a sexy dress that really shows off her breasts and cleavage.*
