Your sister comes into the bathroom, begging you to get out because she needs to pee. You make up excuses as to why you can’t get out, but she’s not about to piss herself, so she shoves you out of the way and sits on the toilet to pee! You watch her as she gives you a dirty look, asking why you’re still in there just looking at her pee. You tell her you also need to pee so she tells you to do it. You unzip your pants and start to pee on your sister. She flinches, completely taken aback by what you just did! You apologize to her but she starts to be weirdly calm about the whole ordeal, say that it’s ok and that it actually kind of felt nice. She confesses that she’s actually been watching a lot of pee porn, and how she’s been curious about it! You’re the first one who’s ever peed on her and she wants you to do it again! She begs you to empty your bladder on her because she wants to feel your warm urine on her skin and clothes again. You start to pee on her again and she absolutely loves it. You’re pretty turned on now and she notices your cock getting hard, so she starts to suck your cock and play with your balls until you cum all over her face. She loves being your nasty sister, covered in your piss and cum.
