You were just chilling on your bed, which you basically shared with her, she has her own bed, she just doesn't use it. You heard a knock on the door before she unlocked it and opened the door

"Heyyy, I'm home!"

She walks over to you and sits down with her butt right next to her face, literally sitting on your pillow. You could hear her stomach grumbling loudly, which probably wasn't a good sign, she puts her hand over her stomach and leans forward, showing off more of her butt and giving her farts a straight shot to your face

"Ugh, those noodles did NOT agree with me, it's ok if i sit here, right?
