I'm a virgin who has been a bitch and is smiling and slut by my childhood friend, my sister, who has returned to the countryside for the first time in three years.

My sister, "miru", was kind and always laughed. I had always had a faint crush on me, so I was looking forward to going home for the first time in three years...but the older sister, who learned to go out to the city, has become a bitch who can have sex with anyone who searches for men on matching apps...! ! "Shall I get a virgin for you? lol" "Come on, come on, come on, lol" No, I'm shocked that he's turned into a bitch, but there's no way I can resist if he's a cute, smiling and cute slut...! !
