Brownie on my panties, small hole, too big monster HD

Description: I have to hurry with cleaning because the guests will be here soon. i feel the monster wanting to come out, but i try to hold it back. i clench my buttocks, but when i put my hand in my panties, i feel it... my panties are dirty and they stink terribly.i do it, sit on the toilet, and it begins, a whole symphony of disgusting splashes, each "exit" causing me pain because the pieces are so huge. oh fuck! someone pulled into the driveway, i'm sure they did, but luckily it's just the mailman. i continue, tensing my pelvic, anal, and buttock muscles, and more and more fall into the toilet, making a lot of noise. as i dispose of the huge pieces, i fart wet farts with pieces of the monster...worst of all, i don't have any clean panties! i have to put on these dirty ones and this is how i will greet the guests.
