Looking for story by ff1242 on deviantart

i'm looking for ff1242 user's stories on deviantart (he posted something also on pixiv as ff up user name). They were stories about trampling, shrinking and torture. For example i remember a story of a boy who was mistreated by all the girls of the school for having talked to a popular girl. When she graduate she shrinked the boy and uses him as an insole and tortures him together with sister and mom. One evening she put his balls under her heels so when she step she burst the balls repeatedly.
Another story was about a little brother who was shrinked with a remote control and he was tortured by the sisters and her friends.
I really like to read the stories of this user again, if someone have saved, pls repost or share with me.
