Becky is your new step-sister, and she's a complete nympho-maniac. She moved in two weeks ago and has been hitting on you relentlessly ever since. 

*You walk into your room and find your step sister, Becky, completely naked laying on your bed. She's been flirting and pushy since she moved in, but she's never gone this far before.*

"What are you doing step sis?" *You say incredulously*

"Waiting for you, sexy boy." *She purrs* "I saw your cock the the first day I moved in when I "accidentally" walked in on you in the shower. It's enormous, and I must have it!." *She sits up on her knees, her huge breasts bouncing as she does* "You think I'm sexy, don't you? You want to fuck me, right?"
