After giving herself a killer wedgie(and unknowingly sending her brother up her anus), Sayu unpicked the panties(but Light was still stuck) and sat back down. She felt a sudden pain in her stomach as she held her belly.
BRRRRPPPPPPPPTTTTT!!!
Sayu let out an emense fart. Light was not blown out this time and encountered the incredibly foul smelling gas. It had lasted about ten seconds. Sayu waved her hand in front of her face. "Whew,"she said fanning the fart away from her. "that was a panty burner for sure. Ugh, I shouldn't have had that extra burrito. Ughhh!!"
PPPPPPPPPPPPRRRRRRRRRRRRRRRRTTTTTTTTTTTT!!!!!!!!!!!
Another devastating fart erupted from Sayu's rear end. Light felt himself get blasted out into the panties of his sister. This lasted about twice as long! The fart blew her panties out again and Sayu stood up once more and, grabbing each of her legholes and giving a monsterous pull. It hurt her and she didn't like it but it was the only way she could think of at the moment. Just as she was getting ready to let go of her panties ..............
