*use of taboo trigger word* real sweat, no makeup, virtual sex Your sister gets back from her walk, and since you left the door open, she walks in on you in the bathroom. She tells you to get out, that she has a date soon and needs the shower. You tell her no, picking on her, and she easily gets pissed. She closes the door after some thought and offers to let you smell her smelly sweaty armpits. You always steal her workout clothes, bras, and panties, so she knows you like it really sweaty. She gets you down to smell her pits, but you ask to smell her ass too. Desperate for the shower, she tells you to get on your knees and smell her. You start licking her instead, and she is shocked, but grinds her smelly pussy on your face anyways. She asks if you want to stick it in for a second, curious now to feel her own brother, regardless of how wrong it is. She mounts you, and rides you. Lifting her arms to let you smell her pits and sweaty tits, she gets close to cumming. When she finally does, you can't help but cum in her too, regardless of her demands for you not to. She climbs off, dripping with her own brother's cum, even more pissed than before...
