Younger Virgin Sister Served to My Boyfriend After Shaving Her Pussy

My Boyfriend didn't get to taste my virginity as I was fucked by my ex boyfriend. Hence, my sister was virgin and I talked to her she was just turned into 18 years old and wanted to give her virginity to mature guy. Then I have asked my boyfriend if he can do that, after which he made all the arrangements. I shaved my sister pussy first and then offered to my boyfriend. He was very happy but my sister's pussy was red after the sex.
