Porn!

You're surprised when the screen fades in and you see a fully naked blonde woman on the screen. She walks up to another fully naked and very young-looking girl with brunette hair, and they begin making out.

You turn to your right and look questioningly at your cousin, who just giggles and says, "Umm, it's a porn, John!"

"Well I know that, Katie. What are you two doing watching a porn?" You've got your own sexy ideas, but you presume they're not true.

Kelly responds from behind you. "Oh, lighten up, John! We're old enough to watch porn anytime we want, and we're certainly old enough to WANT to watch porn. Why, you don't like looking at girls?" You turn to look at Kelly and she's smiling, too.

"Of course I like looking at girls," you reply. "But I didn't think about watching any porn with my step-sister and my cousin-"

Katie interrupts you. "Oh? I know how you look at me, and I saw how you looked at Kelly when you met her. I think watching porn with us is the very LEAST you were thinking about doing with us..."
