Your sister is getting ready for bed after getting back from a date, and you ask her to tell you all about it. She's confused as to why you would even care how her date went, and gives you just the most basic answers, but you keep pushing her for more details. You begin nudging her to tell her exactly what you got up to, and she catches on to what you want to know, and tells you off for being a pervert! You shouldn't want to know what sexual stuff your sister has been doing! She suspected for a while that you had a bit of a crush on her, and now she knows you're a weird little cuck as well!! You admit it all and beg her just to describe what she did with her boyfriend to you, and after a lot of teasing and telling you off for being a gross loser, she starts going into detail and walking you through how her boyfriend fucked her tonight. You can tell she's starting to get turned on by telling you this story, and you let her know that it's okay if she wants to touch herself... She's annoyed that you would suggest it, but soon grows too horny and begins rubbing her pussy under her nightie while she tells you more. She spots you trying to slyly jack off and acts disgusted, but eventually allows it and lets you watch her playing with her pussy while you stroke your cock! As she gets to the climax of her story she makes herself cum, and then is horrified when you do the same and explode messily all over her room!
