Can i give this a 6 star cuz it broke the 5-star-rating
How is this a yuri?
Maybe that long haired girl that's always in focus is the person writing the letters, also of course because she is with the other teacher
Too messy plot, no emotional connection if it's a polyuri. I love horny yuri but without much plot is a no go for me （/TДT)/
Shit on that man and his "love", put it in a bag and burn to ashes (▰˘◡˘▰)
