MUFR-004 - The day I crossed the line with a mere female friend. ~From a lighthearted prank, our friendship evolved into a friends-with-benefits relationship~ (MUFR-004)

A close-knit group of two men and one woman. The female friend, Miko, is generally a recluse and not comfortable with closeness between girls, so she doesn't have many female friends and has been hanging out with male friends since a long time ago. When they came to play at a hotel, they decided to play a game where the loser of a prank would "show their masturbation" as a penalty. The man who proposed it lost and started exposing his penis and masturbating in front of the two of them... Miko also became very interested in seeing her male friend masturbating for the first time... While playfully using a vibrator and playing around, she started helping him masturbate. Miko also seemed to be getting excited, and started enjoying the atmosphere, eventually licking her friend's penis and even performing oral sex. "I feel like this isn't a penalty for me...?///" Just yesterday, the three of them were friends without any romantic feelings, but they couldn't resist, and before they knew it, they were having sex as friends of two men and one woman. It wasn't intentional, but with just one moment of curiosity, they became a relationship between two men and one woman. After all, friendship between men and women doesn't exist. The day their friendship collapsed.
