The fifth installment of the series finally arrives! It captures the girls teasing their sensitive areas with plain, unrefined finger movements. Their faces twist adorably, their bodies trembling slightly, as if overwhelmed by pleasure for the first time. The girls aren't yet accustomed to these sensations, completely immersed in their private world. Being unable to hold back until they get home after school is part of the thrill—especially when the bathroom becomes their secret sanctuary, heightening the sensation. Once again, after class, they indulge in solo pleasure without a care for who might see.
