As I stand there and watch my sister fuck herself, I can't help but get amazingly aroused. Maybe if she hadn't been so fat when she was a teenager, I might have snuck peeks at her then. But since she's a knock-out, and since I have balls bluer than ice due to no sex recently, my hand creeps down into my pants and I start rubbing my hard cock slowly.
Monica continues to pound the dildo in and out of her moaning, "Fuuuuuuck! Fuuuck me! Yeah! Fuck me haaaaaard, baby! Yeah stuff my cunt! Unh! Unh! Yeeeaaahhh! Just like that! Fuck me like a slut!" I get a little braver -or perhaps a bit more stupid- and unzip my pants, whipping out my cock as I start to beat off for real.
All of sudden Monica opens her eyes and sees me standing there, wanking off as I watch her wank off. "Ross!" she yells. |
