(This was originally filmed as a custom video, and the name Mikey is used throughout) You and your sister are hanging out in her room playing video games, and your sister seems to be unaware that you've got a great view up her skirt! She asks you if the laundry is ready, and you apologise and admit that you forgot to put it on. Your sister is annoyed and reminds you that all of her panties are needing to be washed; she doesn't have any clean pairs, and the pair she's wearing right now is super dirty! You laugh and she gets even more annoyed, shoving her ass in your face and making you smell her dirty underwear, whilst telling you off for not doing the laundry like you said you would! As she's pushing your face into her dirty panties and mocking you, she starts laughing so hard that she accidentally pees herself! As your face is being pressed up against her ass and pussy, you even get some of your sister's pee on your face, before she realises and lets go of you! She's embarrassed and annoyed, showing you the pee stain on her panties and having a go at you for making her laugh and making her piss herself! She takes off the pissy panties and tries to go back to gaming, but you're now fully distracted by the sight of her bare ass and pussy before you. When she realises you're not paying attention to the game, she demands that you get naked too, as it's not fair that she's there with no knickers on while you're fully clothed! You strip down and your sister sees your erection, and though she complains and calls you a pervert she immediately starts rubbing her pussy! She says she blames you for getting her excited, and that you shouldn't have taken your clothes off if you had a boner, but now that she's seen it she's gotten turned on! She demands that you stroke your cock while she plays with her pussy, and bossily commands you to cum with her, since this is all your fault!
