Sayaka: The Cute & Careless Girl (2009)

Synopsis

How does a teenage girl shed her virginity? She is horny, curious and dying to have sex. It is so bad that she cannot take her eyes off the teacher's crotch. Well, the usual and time-honoured way is the answer. She joins a virgins' club at school and practices showing off her body, underwear and up-skirt. It is not so easy though. It takes practice, but she has little time before she and the boy she is tutoring get together.
