HUNT-782 - The strict sister who nagged me finally turned into a total slut

An older sister masturbating while peeping on her younger sister's sex life. I thought this would be 'killer content,' but in the first three episodes (out of four), she barely masturbates. She doesn't even finish. You finally see a little bit in episode four, but that hardly makes it 'killer content.' Even if she wasn't peeping, she could have just heard the sounds from the next room and started masturbating. There was no need to do it in the hallway. Also, the sister dynamic doesn't really matter to me; I just wanted to see a horny woman masturbating while watching others have sex. If they were going for a sister theme, they should have cast someone who looked similar, and I wasn't a fan of the younger sister having bigger breasts. If I'm being greedy, I wish the younger sister had been fully naked and they had cast someone with huge breasts. I guess they kept them clothed so you could tell who was who, but still... In these 3P scenes, I hate it when the 'leftover' girl just stands there blankly. She should be doing something—either lesbian stuff or masturbating. Just standing there sucking her thumb isn't sexy at all!!
