Unknown wake up call

It was early Saturday morning the whole dorms was quiet seem like everyone was still asleep in their rooms. Katsuki rubbing his head yawning as he sat up in the bed "damn it's to early but oh well I'm going to get up" he said to himself walking into the hall to the bathroom he gets their and turn on the shower water with his unknown knowledge he didn't know one of the girls pranked him.He opens up the medicine cabinet when there was a big flash"Ahhh! " Kat replied as his body began to shrink to ant size.

"S....shit what the hell happen to me" he yells looking around in the steamy bathroom as he hear banging of feet coming near as he was going to find a place to hide the door came right open standing in the door way was a half awake Mina. Katsuki stood on the back of the toilet rim saying his arms"mina I'm down here" he said trying to yell but his voice was muffled.

Mina yawning loudly as she was rubbing her stomach walking closer to the toilet she didn't even know he was there as she turned around removing her clothes she bent over to sit down and let out a loud and long fart"eh?? That felt good and ew it stinks too" she said with a giggle as she sat down knocking him down from the gas he landed in her underwear katsuki looked up at her being dizzy"M....Mina I'm down here" Katsuki said trying to move himself

She was having real bad gas and what it sounded from having the runs after two hours she wiped herself and than she reached down pulling up her panties where it was two late for you to get out mina pulled them up as your face was right up against her butthole"I...I'm down here let me go"Katsuki struggle to move since her ass cheeks were tight around him as she walked out to head to breakfast "Hey is breakfast ready I'm starving "mina yelled as she flopped right on the chair pushing Katsuki face closer to her butthole

Hours after mina ate breakfast she relaxed in her room "mmh why does it feel like my stomach hurts "she said loudly a moment of pause Katsuki heard Loud Noises coming from her butthole "n....no don't you dare mina let me out of here now" he said trying to wiggle away from her butthole mina was laying on her bed still grabbing her stomach again "s...shit I can't hold this in anymore I need to let it out" she said as she lifted up her leg letting out a loud and long stinky fart"ahhhh! I think theirs more "she said as she pushes again more gas comes out hitting him in the face "n....no" kat said trying not to pass out

A moment after that second to last wet fart she grab her ass pushing him up inside she quickly ran to the nearest bathroom " ahhh!! I'm going to have the runs again " she yelled clinging her ass cheeks as he was getting completely cover with shit.

"N.....no what the fuck is going on where the hell and I why can't I move" he yelled being pushed with loads of shit come down as it was giving her a lot of pressure down their to hold back  

She quickly made it to the toilet as she try pulling her pants down quickly mina grip ahold of the sides and pushed it was coming out of her like wildfire he got pushed out into the toilet kat looked up noticing where he was "crap I need to get out of here " he yelled as he was looking for a way to climb still going on mina was having the runs above him"ahhhhh!!! There comes a big one" she yelled gripping the toilet more and she pushed harder and harder a big long turd was coming filling up the toilet.

Kat managed to climb out and made his way to the hallway "damn it that was a close one" he said to himself as he made his way to the kitchen to see if he can get someone attention. He gets to the kitchen and notices round face was making food for herself "this is worth a try" he answered himself climbing up into the counter to get her attention "Ochako down here please help me " Kat yelled waving his hands hoping she would notice him
