anyone know the doujin where the sister has her boyfriend fuck her younger sister so she has experience with men? i think it ends with the younger sister naively announcing in public to the guy that her new boyfriend doesn't have phimosis like him and the older sister laughing

Man, love her (and her mom's) character design. Super buxom with a bit of sag, and the artist is really good at conveying how soft and squeezable they are. Definitely the biggest appeal of the series to me--I found the sex scenes themselves kind of boring though.
If the scenes were more interesting, it'd probably be one of my favorites.
