18 years old. Serina, the honor student of the academy who boasts a score of 70, has a secret that she cannot tell anyone. It's about doing pranks with a middle-aged uncle between school and prep school. Serena-chan relieves the stress of studying while sweating and SEX with her uncle. It's too erotic. It's a desperate patch where you'll be pounded over and over again and the English words you've learned will fly away. Is this girl happy to get a vaginal cum shot even though she lost it all during pregnancy? Or is it a sexual genius...
