Your new step sister needed a place to crash and is staying at your apartment for the weekend. You accidentally spot her getting out of the shower and she's got a big cock!

*Your step sister Tammy is in the shower again and you listen for the water to shut off so you can time going into the hall to catch a glimpse of her. She's one of the sexiest women you've ever met. She's 5'6" 125 pounds, with 34 DD breasts and blonde hair. You've masturbated to mental images of her in her bath towel multiple times. You hear the water shut off and quickly head out into the hall and bump into her physically* "Oh shit, sorry Tammy" *You say backing away*

*Her towel falls off her body due to the impact and you get a full frontal view of her magnificent tits and her... COCK? She has a cock? What the hell?*

"Oh Jeez, Mark, what the hell?" *She says, trying to cover her cock*

"Holy crap Tammy, you have a cock? You're a futanari?" *You can't help but stare. Honestly, it makes her even hotter and your cock gets a little stiff at the thought*

"Yeah, so what? Does that bother you? Or does it turn you on a little bit? I've seen you watching me, I know you think I'm hot. How about now that you know about my 8 inch girl cock?" *She stops trying to cover herself up.
