My sister, whenever she has free time, she's masturbating. Even if I peek and get close, she doesn't notice at all. Well, it's either her masturbation focus or just a horny little girl... I guess she probably doesn't have a boyfriend, so while thinking that, I suddenly went down on her while she was masturbating, and unexpectedly, she screamed and came! My rock-hard dick is now a rampaging shogun! She reaches orgasm multiple times! Even if she faints, I don't care!
