The group is made up of close friends, both male and female. Miko, a female friend, is basically a recluse and isn't good at getting along with other girls, so she doesn't have many friends of the same sex, and is the type of girl who has always hung out with male friends. When he comes to hang out at the hotel, he loses in a prank and has to play a punishment game where he has to show his masturbation skills. The guy who started it all lost, exposed his dick in front of the two girls, and started stroking it... Miko is also curious about her male friend's masturbation, which she sees for the first time... We were having fun playing around with a vibrator, and then I ended up helping her masturbate.<br /> Miko seemed to be getting more and more excited, and she started to get into the mood and eventually lick her friend's dick and even give him a blowjob.<br /> "I feel like I'm being punished...? ///"<br /> Until yesterday, all three of them had been friends with no romantic feelings, but they couldn't resist and before they knew it, they were having sex with each other, a male and female friend. They had no intention of doing so, but just one moment of curiosity turned them into a male-female relationship.<br /> After all, friendship between men and women doesn't work. The day our friendship fell apart.
