Kronii had self-confidence issues
you knew it from the beginning, but with time it seemed like she was getting better
then you've started sleeping together and she began to have doubts about your sex life
she didn't believe that you found her amazing enough to not want something more
she was constantly asking about your fetishes
you begrudgingly told her a few that you thought she might be okay with and she started doing them happily
when asked she denied having any fetishes of her own
all seemed well again

one day she gets back home with the squirrel
"anon, why didn't you tell me that you wanted a tailjob from Risu? I went back in time and saw you spamming that on /vt/"
the girl in question is giggling, her tail moving playfully
"I told you anon, just be open with me, I'm okay with everything"
while you're still in shock, she undresses you and guides you to the bed
then she lays down by your side
Risu sits on your belly, her tail slowly wrapping around your cock
her soft, well groomed hair is teasing you in just the right way
she's moving so slowly
too slowly
Kronii notices and asks her about it
"I said that I would give anon a tailjob, not that I would make him cum"
she really should've known better than to mess with the warden of time
with a simple hand wave Kronii de-ages the squirrel
"aunt Kronii, what's happening?"
"r-remember how you said that you want to tickle anon with your tail?"
you look at Kronii
she's still laying on her side, both hands working furiously in her panties
so this is her fetish
Risu starts moving her tail
it's smaller and softer than before
you close your eyes
this is so wrong
so very wrong
yet you can't stop yourself from uoooooohing
Kronii gasps and starts shuddering
you open your eyes
the clothes are too big for a little squirrel
you can see her flat chest and small nipples
you can't take it anymore
you grab her, bring her down, and hug closely as you cum in her fluffy tail
some time later you let go and she gets up
"aunt Kronii, my tail is sticky..."
"anon is gonna give you a bath, right anon?"
