I needed to do laundry today so I headed downstairs to make sure the machine was available. That's when I spotted my punk rock step sister naked and alone, playing with herself on the washing machine. She only had pink panties and black boots on! She looked amazing--I've always admired her body. I panicked and hid behind a shelf. I didn't know what to do... so I just watched. Her pussy was really wet. I could hear the juices sloshing around when she rubbed herself with her fingers. I normally don't care for tattoos, but hers look awesome. She is so cool I wish she would hang out with me. I tripped and made a noise. She busted me spying on her! I tried to play it off by asking her, incredulously, what she's doing. She said she was doing laundry and that I was supposed to be at school. Yeah, well I guess I'm home early today. All of a sudden, the mood shifted. She walked up to me and grabbed my cock. I was shocked at first, but then she reminded me that we're not related, so I guess this is OK, right? She got on her knees and started sucking my dick. She really wanted me to not tell mom. She gagged on my penis which made me feel good. I stood her up and turned her around to admire her round big ass. She has a tattoo on the back of her legs that reads "Fucking Princess". She is a wild one, that's for sure. Her pussy was wet, warm and ready for action. I put my dick inside of her cunt and smashed it doggystyle. I took a step back to admire her pussy some more. It really is nice, isn't it? It might be the nicest pussy I've ever fucked. I continued fucking her hard on the floor. She turned around and put my sausage back inside of her mouth. She bobbed her chicken head up and down really quick and finished me off nicely. I came all over her small tits and she seemed really pleased with herself. She mentioned we were going to have a lot of fun living together. I told her we'd do all of our laundry together from here on out, which she got a kick out of. I am really looking forward to it.
