After a long, hot afternoon sitting next to the pool your sister tells you that she noticed you checking her out in her bikini... and she liked it. She knows it's wrong to think about her brother like that but she gets so turned on by it that it makes her take off her top to show you her beautiful tits. She's noticed you staring at her big round ass at home too and she's excited to use this opportunity to show it to you. Did you ever think that your hot sister would want to fuck you too? As long as you don't tell mom and dad, your sister will take off all her clothes and let you watch her masturbate- rubbing her clit, fingering herself, and moaning- until she cums to the thought of her brother's cock.
