Your little sister is so excited your back home and she has something to confess. She really really likes you and not in a brother sister kinda way but the other kind. She talks about how her friends in school play with their brothers and how she wants to try throat fucking. You agree as long as there is no sex. You end up changing your mind tho and decide to fuck. Shes riding your cock saying how much she loves it. It ends with you blowing a huge load all over her.
