Nao-senpai, a year older than me, welcomed me with a gentle smile when I joined the literature club. She was a beautiful person with a clean, calm atmosphere, usually wearing glasses. "Can I lick your nipples?" With those words, our relationship changed. "I'll be your first woman." From the day she took my virginity until her graduation, this is the record of my youth, being fucked anytime and anywhere as her sex slave.
