A simple story of a sister and her friends crushing her little brother would be the best description. It's mainly about trampling, squashing, a little foot worship, but I guess you would classify it as general BDSM.
Story about how hard it is to be a teenager in today's messed up society. Also, this kinda turned into a romance book. Mature because of language & smut. There is sex in this & I'm giving credit to my friend for writing it cuz I can't do that kind of stuff since it makes me uncomfortable.
