please help!!

i totally forgot to save this one i was reading and i cant remember the name for the life of me (︶︿︶)
anyways, the author is actually someone who collects erotic stories from her followers and she's made it into a collection.
the first story was about a girl who moves into her friend's place (the friend lives with her boyfriend) while job hunting ig? and during the first night she catches her friend having sex with her boyfriend. 2nd night she catches them again but she ends up masturbating to them. 3rd day the friend and her boyfriend invite her to have sex with them

and the other stories were one about exhibitionism, a guy having sex with his friend's mom (the guy was in love with her since he was a boy), a girl who accidentally video calls her friend while masturbating to said friend and they end up being a SM couple

please help me out with this one !! ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄
