Ten years ago, I gained a stepsister through my parents' remarriage. But my stepsister is a shut-in otaku... Even after returning home after a long time, she's still the same, hiding away in her dorky glasses. But upon closer inspection... she's braless, and our eyes meet over her exposed nipples?! I couldn't resist her masturbating stepsister, so we got close quickly! We fucked everywhere, hiding from our parents in the bathroom, bedroom, and even in the hallways and kitchen! Turns out, my stepsister is actually cute, incredibly lustful, and the best stepsister ever!
