Silent rape, an unpleasant but unspoken literary girl, Yumeno Aika SSNI-325

Not wanting anyone to know she was being violated, she could only obediently cover her mouth and endure until it was over... The guilt of losing a precious ancient book and her obedient personality led to the girl being violated in her favorite library! Ayaka Yumeno, too afraid to ask for help and crying out of fear, was repeatedly penetrated by the dirty penises of adults!
