An older sister radiating pheromones hides a fetish! Licking anus to impart scent and taste, enticing others to see her licking her plump, large buttocks—a seductive act by Hiiragi Rion (DLDSS-271).

My idolized older sister, who replaced my mother who died when I was young, got married and left my parents' home. A month later, she suddenly returned! I can't even ask you why… One day, my drunken sister asked me, “Someone told me it's caused by couples having sex, but I don't know what's wrong, so I wanted you to try it.” And so, I started incest with my favorite younger sister. It began, but I was surprised by my sister's unusual fetish. “Hehe, try it again!” The best “anal-licking siblings” in history is born!
