You catch your sister sneaking in from a party. She knows the rules. If you want her to keep her secrets she has to take care of you. She starts laughing when you ask to fuck her. Do you really want 10+ guys sloppy seconds? There is still cum dripping out of her pussy and she's covered in used condoms. You fuck the slut anyways and add to all the cum in her pussy. (trigger word, sister, brother, family, taboo, ebony, creampie, used, slut)
