While on vacation, I catch my sister making content for her fan site. That night, I take advantage of the fact we have to share a bed by playing a bit. The next day I can't take it anymore. I tell her she has to give me a lap dance if she doesn't want me telling our parents about her fan site. She agrees! The lap dance turns into a blowjob, but that's not enough for me. I have to creampie her wet pussy! I don't even care that she's not on birth control.
