FNS-087 English Sub: I couldn’t resist the temptation of my girlfriend’s sister’s plump buttocks

When I went to my girlfriend’s house for the first time, her older sister, Ranran, came home. Unlike her, Ranran looks like a model. Muhuhu! A few hours later, when I went up to the bathroom, I found the door to Ranran’s room…! I peeked in and, to my surprise, she was lying there without wearing any underwear. I panicked and fell, and when Ranran noticed, she blushed and asked, “Were you peeking?”, while protruding her buttocks and teasing me with her panty-less rear. “Maybe you like the anus hole? Want to lick it?” From there, I tasted her anus and eventually licked it repeatedly, becoming a reverse rape instructor. Ranran’s anus pheromones are truly the best!
