FNS-087 My girlfriend's sister was a devilish girl with no underwear on, but I couldn't resist the temptation of her plump ass as she climaxed in agony with anal cunnilingus.

When I went to my girlfriend’s house for the first time, her older sister, Ranran, came home. Unlike her, she looked like a model. Muhuhu! A few hours later, when I went upstairs to the bathroom, I found the door to Ranran’s room…! I sneaked a peek and, to my surprise, she was lying down without any underwear on. I panicked and fell over, and when Ranran noticed, she blushed and asked, “Were you peeking now?”, sticking out her butt and seducing me with her pantyless ass. “Maybe you like anal holes? Wanna lick it?” From there, I stole a bite from her asshole and ended up licking it over and over again, becoming a reverse rape instructor. Ranran’s anal pheromones are really the best!
