My favorite idol is my little sister!? The morning after I fell asleep drunk, I woke up to find my naked sister in the same bed... "I think I've become addicted to having sex with you, big brother." Apparently, last night, while half-asleep, I crossed the line with my favorite idol (my sister). From there, my sister, who used to make fun of me, suddenly turned into a clingy little puppy, whispering and begging for me to cum inside her! Big-dick brother and big-breasted sister have sex and cum inside each other all the time behind our parents' backs! A lovey-dovey incestuous life where the same genes intertwine!
