A stepbrother over 20 years older who was created when my mother remarried. Commonly known as a "kodo-oji" (old man who preys on young women). He's gross and a NEET, the worst. One day, I was overcome by a heat I had never experienced before and an uncontrollable urge. I had been slipped an aphrodisiac... Furthermore, my brother forcibly inserted a dick with aphrodisiacs... What is this pleasure, to feel this good with a stepbrother I hate so much... I, who was trained by my brother's aphrodisiac dick, became a bugged meat toilet that sprays semen and cums like crazy, and was repeatedly violated.
