## Description
“With this, it's impossible to flirt with girls...!”

I died in a car accident while still a virgin,
and was reincarnated as a cute girl named “Tanya”!
On top of that, my sisters are always being mean to me for some reason...!

If only there was something I could do to gain the upper hand...
Then, a gruesome item from the black market caught my eye!
—Wearing this ring transforms the clitoris into a “penis.”

“What I was missing was a penis...!”

However, my older sister took advantage of a momentary lapse and stole the ring...!
This is like giving a demon a club... no, “giving my older sister a penis”!
