Ultra-Kinky stepsis wants my hard-on

When my stepsister caught me wanking while spying on her as she was doing the same I was so freaked out I was prepared to do anything to have her not tell mother and parent about it. Imagine my shock when she said she was mischievous and dreamed to plumb me. Wow! I mean she's just my stepsis, right? She's red-hot and she gargles beef whistle nicer than a vacuum machine. This super-bitch railed me like a cowgirl and made me spunk right in her hatch. Fellow I enjoy our insatiable family!
