For 3 Days While My Girlfriend Was Away on a Trip, I Was Thoroughly Anally Trained by Her Big-Titted Gyaru Sister Until I Was Brainwashed into Female Ejaculation. Arisu Otsu
For three days while my girlfriend was away, I was taught the pleasures of anal by her older sister, and I became hooked on the sensation of female ejaculation. I was surprised to discover how incredibly pleasurable the anus—something I'd only recently grown curious about—could be. "You always acted so manly in front of my little sister... but the truth is, you're just a sensitive anal-slut who cums from being fucked in the ass, aren't you? You don't have to pretend to be strong anymore... Just expose your cute, vulnerable self completely to me," she said, thoroughly training my ass until I finally felt like I'd discovered my true self.
