You can read them in any order as long as you read the chapters of a story about a specific girl in number order.
Several stories have girls with the same name but as far as I can tell it’s different girls.
In the Blackmaled series I would include
50 Shades of Black 1-7 (Gemma)
50 Shades Blacker 1-8 (Lucy, Gemma’s sister)
Black Takes White 1-6 (Kelly & James)
Blacked 1 Sexting One (Amy & Aaron)
Blacked 2 Revenge (Jenny)
Blacked 3 Anniversary (Faye)
Blacked 4 Prom Night (Anna)
Blackmaled Amy’s story 1-4
Blackmaled Cara's Story 1 (+ 2-5 I haven’t read)
Blackmaled Faye's Story 1-4
Blackmaled Free Christmas Gift (Karen)
Blackmaled Karen's Story 1-4
Blackmaled Kirsty's Story 1-4
Blackmaled Layla’s Story 1-5
Blackmaled Lenka's Story 1-4
Blackmaled Paige's Story 1-4 (NOTE 5 parts because one is named 1.5)
Blackmaled Singles Jenni
Blackmaled Singles Suzi
Blackmaled Singles Tanya
Blackmaled Zoe's Story 1-5
Queens Gambit
Maybe Blackmaled - Several of the episodes would fit in Blackmaled
7 Deadly Sins 1-8 (Gemma) - This is a favorite of mine
Not Blackmaled but clearly happening in the same storyverse
Mischievous Anne's Story
Mischievous - Fight Club (Helen)
Pandora 1-6 (Jenny) - Another of my favorites
Raunchy Business
Watch Me (Katie)
