MUFR-002 The day I crossed the line with a female friend. From a little playful mischief, our friendship changed into a casual relationship.

A close-knit group of friends made up of both men and women. Kanon is a bit blunt and easygoing, so she has never had many female friends and has usually spent time with male friends since childhood.

On a whim, the three of them decide to go to a hotel that recently opened nearby. At the hotel, they get carried away, and when the guy who lost at rock-paper-scissors starts jokingly stripping and pleasuring himself in front of them as a punishment game, Kanon is initially amused, but before long she becomes genuinely curious about what he is doing.

What starts as playful, suggestive behavior among friends gradually creates a more charged atmosphere…

Even though she usually acts so cool and unfazed, Kanon becomes completely captivated, and it gets a little too serious. She never meant for things to go this far, but with just one moment of curiosity, the relationship has already become one between a man, a man, and a woman.

Later, when they go out together again, things even get awkward in a way that makes it hard to hold back, and as they keep teasing and fooling around, the three of them end up crossing the line once more.

After all, friendship between men and women is not so simple.

The day their friendship fell apart.
