This was amazing! This is perfect length of a chapter!! really well done. I like longer chapter a lot more. you also did well with the details this time. Maybe you could even add some more humiliation from the mother like her being in a bored mood, having a phone call with a friend and talking about her "shitty son" and her son sobbing listeing to it where in fact he was a shitty son, literally. and at that moment her releasing a foul fart into his sobbing face. I would love her taking a dump again in the morning with her son this time stayin inside her ass, and a turd slowly sliding over him, and glueing him to the walls, him screaming, and then the shit slowly ramming inside his face, mouth, down his throat, and him vomitting down into the toilet. totally white/greenish face, nearly passing out from the experience. and his mother just carelessly releasing a fart as an answer of his sobbings. I also thought what if he shrunk again and totally would become an ass parasite, as the lowest possible thing imaginable. Then in another chapter he could get inserted inside her rectum and maybe even shrink again, and totally becoming a nano ass parasite, where another bowl movement would collect him again inside a turd. This is the best story Ive read in month, keep it up man. Good ass plots are never to be found anymore.
