[MUFR-002] The day I crossed the line with just my girlfriend. ~From a little prank, our friendship turned into a saffle relationship~

A good friend of both men and women. Kanon is a bit sloppy, so she doesn't have many female friends, and she's always been the type to hang out with her male friends.
The three of us decided to go to a hotel that was built in the neighborhood. When I got in a high mood at the hotel and lost in rock-paper-scissors, my male friend started taking off his and handling the in front of me with the intention of "masturbating" in a punishment game, Kanon was amused at first, but he was curious about his male friend's masturbation.
When I was doing erotic things with my friends, it gradually became that kind of atmosphere...
Even though I'm usually sassy, Kanon cumming on my was too cute and I was a little too serious.
I didn't mean to do that, but with just one curiosity, it's already a relationship between a man and a woman.
If I go out to play later, I'll even pee in front of me, and even my friends can't stand it.
I was playing with my sloppy, and then the three of us decided to have sex again today.
After all, friendship between men and women is not established.
The day our friendship broke down.
