Sibling Rivalry
by Jay

There was a long pause and Joe could hear nothing but is own heartbeat. The pressure on his face gave slightly as his sister slowly raised her ass from his face. This was a normal occurrence in the house though for Joe’s sister often employed this form of attack on him. “I hope your ready for this Joe” she said, released the tension in her stomach whilst pushing down on Joe’s stomach. As he expelled his remaining oxygen he felt a breeze on face as his sister let go of a powerful SBD. Pfffffffffffffff. He struggled to get away but the ropes binding him were too tight. His sister's butt came back down again sealing in the terrible stench and his eyes started to water from the fumes, Pbbbbbbt this fart blew long against his face and the smell intensified. Again his sister raised herself turned to look at her captive with her backside pointing straight into his face and opened fire with a barrage of farts, a slow tendril of green gas rose from her ass and she waved it into her brothers face, “how do you like some of that” she said. Joe was close to passing out but had managed to hold on this long, passing out would only make it worse on him later but as the gas reached his nose he immediately fell back onto the floor and started to gag. This was his sisters trademark weapon, no-one knew what had caused it but she was born with this ability and since he was born two years later with no special talents at all she took it upon herself to make sure he was reminded of her superiority.

A week later Joe was sitting in his room having just gotten out of bed and still in his pajamas, the mid morning frost meant that the house was freezing up until about noon-ish. The Skunk as he referred to Angela, his sister, was still asleep in her bed. He got up dressed and was looking for his socks when he noticed under Angela’s bed there was a book and not just any book this was only her freaking diary. He stared for a moment thinking of the embarrassment he could cause his sister at school and she would never know it was him. He gently walked across their shared bedroom and dropped to his knees placing his arm under the bed he realized what a terrible position he had put himself in. Angela’s butt slowly poked out from under the covers and all he could do was stare at it the thin thong she slept in was especially tight, hopefully his sister was asleep.

Angela knew where her little brother's head was and what he was looking for. She had been awake the moment he stood up out of bed. ‘1, 2, 3’ she counted

Joe’s fingers curled around the diary and he looked up in triumph, Braaaaaaapt his sister butt said to him. The noxious fumes surrounded his head and he felt woozy. As he tried to back away his sister farted again and everything went hazy, he turned away but his sis was out of bed now and he couldn’t get off the floor. She stood in front of him in her bra and thong, bending over released more gas into her brother's face, Braaaaaaaaaapt. She heard him collapse behind her and nodded in a happy way for this little attempt would cost him dearly later on that day.

Joe sat in lessons looking out of the window in a very bored way until the teacher caught his attention. “Joe I have received a note from the headmaster, you must go to the sports hall and meet your sister there.” Joe left wondering what could possibly have happened that would need him to go home. He entered the empty sports hall and went into the unisex toilets to pee, he found it odd that the hall was empty; he supposed Angela was on her way there. The toilets being disabled toilets had a porthole about a quarter way up the door so it was possible to open or close this if necessary or in case of emergency. Somebody had jammed it open and apparently twisted the hinge 90° so it wouldn’t close. He turned when he finished peeing as he saw movement. The door slammed shut and he heard his sister's voice from beyond the door. “Well, well, well, look what I found, I caught me a thief and by law I can incapacitate you ay way I like”
“Ok sis jokes over open the door”
“Fraid not Joseph”

Joe froze as he heard the sound of nightmares; zip went his sister's fly, the chink of a belt buckle and the ruffle of dropping jeans. He remembered this morning and backed against the cell wall. A naked ass covered the porthole and then let fire with a series of blasts. Braaaaaaaaaaapt booooooooort pfffffffffffffffffffft. To Joe the smell was toxic, all of them combined leaving him in a stupor. The ass cannon fired again sending more farts his way. The air was thick with farts now and was becoming tinted with a yellowy green haze. The ‘Skunk’ was definitely on the top of her game as a laugh came from the other side of the door. Before Joe could realize what was happening he gagged on more rank fumes as his eyes burned and the already tiny toilet which was the size of an airing cupboard really seemed to shrink. More yellow gas was in the room now, his eyes burned as Angela gassed him some more.

Angela opened the door onto her brother and pulled him out of her gas chamber, she was not finished yet. A boy walked into the sports hall and stopped to stare at Angie with only her bra and thong on, she grabbed him by the collar threw him against a wall and as he sank down she turned her back on him and let him have right in the face. He was unconscious in seconds.

Joe awoke to a startling sight, there were people all around him; all boys near enough to his age, one was almost crying, most were unconscious. “What’s going on” he asked the oldest looking.
“We were all brought here for the same purpose and fate”
Joe thought for a moment and became pale, this meant that there were more people like Angie and this in turn meant that there were more people like him. They would all suffer under the ass of one of the woman here but which one...
