I am fan of NTR/Cuckold stories and i am also fan of of age regression stories. So i had a idea to combine both but due to my poor english i can't write story so i am putting forward this idea.
This is going to be Minato x Kushina x Sasuke (sasuke can be replaced by guys other than naruto but i prefer Sasuke). Basically Minato will be cuckolded by Sasuke But Kushina will never stop loving Minato even if she humiliate him (optional)
