I love slutty kushina stories quite a lot and while I don't think there's enough of them to begin with, I believe there's definitely not enough kushina fuccking younger men and boys fics.
So here's my challenge/story idea:
Kushina Uzumaki still has naruto so she's still a mother. Whether minato dies or not is irrelevant to the story. She survived the nine tails. Attack on konoha.
However as naruto grew older kushinas sexual inhibitions waned and soon enough she starts fucking younger men and eventually younger boys around her sons age.
I.e she's fucked by konohamaru on occasion, she teaches at the academy and ends up getting fucked by her class of boys, etc
What I want to see:
Kushina is depraved and doesn't care she's fucking younger men and boys but still loves her family
Big breasts
Blowjobs
Titjobs
Gangbangs
Dirty talk
What I don't mind seeing:
Alive or dead minato (either works)
What I do not want to see:
Naruto x kushina (there is honestly far too much as it is)
Scat
Guro
Incest
I look forward to seeing if anyone is interested in this idea.
