My Straightlaced Childhood Friend Gets up to This and That

I have a problem I can't tell anyone about…

I….
have a bad habit of imagining the girl I love?Yui?Having sex with other men.
I can't stop fantasizing about her being ravaged by a classmate, a kind upperclassman… even our teacher.

Then one day, I was asked to deliver something she'd forgotten to her house.
When I found her fast asleep, I was suddenly overcome by a dark, twisted urge…

A perverted prank is about to go way too far…!
