Side with Rachel

You've had a lot of fun with your kid sister, and put her through more than you thought she could endure. You reckon she's earned a break - at least until you get a craving for young, tight, incestuous pussy. In the meantime, you don't see why Tommy should get all the fun. You close your eyes and go red in the face trying to imagine life as it was before you started violating Rachel's body, but all that you can see is her face covered in your semen and her pussy and ass-hole gaping and dripping wet.

You change tactics and try to recall one of the old jerk-off fantasies you used to have about her every now and then growing up. You remember stalking her friend's facebook profiles for revealing selfies and visualise your favourite one. In the photo Rachel was dressed in a miniskirt, glittery top and high heels, pouting up at the camera with one of her friends at a club. Her friend had flipped Rachel's skirt up, showing off the lacy panties beneath. You remember the shitstorm that erupted when your parents saw the image, and it was taken down soon after. Of course you'd already saved it. You must have cum gallons to that one picture over the years.

You open your eyes and there she is, all slutted up just like in the photo. In fact, her whole room has changed! There's a variety of dildos piled up next to her bed, including a particularly scary looking thick 18 incher. Vibrators, anal beads and even a few discarded cum-bloated condoms litter the floor. Your sister lies on the bed unaware, watching porn on her laptop with headphones in. The same miniskirt from the old photo is bunched around her slim waist, the panties hanging from one ankle as she grinds her pussy against a stack of pillows piled under her juicy little butt. The scent of pussy saturates the room. Oops, it looks like you accidentally turned her into a complete slut! Oh well, at least her room is relatively clean, and Tommy is nowhere to be seen. Close enough!

"Come on David," your mother says, walking out the room. "Leave Rachel alone, you know how she gets when she's horny. She'll be at that for hours. Honestly, I don't know where I went wrong with that girl!"

You shake your head and laugh. "Hey mom, can we order in pizza?" you say, following your mom and leaving Rachel to grind out yet another orgasm.
