Pick a safe answer, and tell her you'd lick her pussy.

I wasn’t sure there even was a right answer to this question. I mean, we were just TALKING about sex, and things that might feel good at the time would probably all sound dumb if I said them out loud. Which is when I realized--it didn’t matter what I would actually do, I just needed something that would sound good, something that would show I wasn’t a guy who only cared about my own pleasure.

“I would lick you to a screaming orgasm,” I told the stepsister I barely knew, with a confidence I barely felt. Her eyebrows lifted into a skeptical expression, and peripherally I saw something like shock on the faces of the twins, but what I really noticed was that the fire in Traci’s blue eyes was burning brighter now. I knew she’d never admit it, but the idea turned her on. Encouraged, and feeling like I couldn’t possibly embarrass myself in front of my stepsisters any further today, I decided to keep talking.

“Right here in this kitchen, Traci,” I told her, my voice soft but with a note of intensity that wasn’t totally fake. “I’d get down on my knees in front of you and lift up that cute short jean skirt you’re wearing.” I’d been admiring it--and the way her long legs traveled up and up and up until I couldn’t see them any more.

“Then I’d slide your panties right down your legs, and plant soft kisses around your slit.” I’d never even seen a vagina in real life, but I’d watched enough lesbian pornos to pull off this description. “My tongue would dance across your lips, and then I’d trace light circles around your clitoris. By the time I was slipping my tongue inside you, you’d already have grabbed the back of my head and be pressing me tighter against your crotch. Soon, you'd be riding my face as I brought you closer and closer to the edge. With my mouth moving back and forth from your clit to your lips, it would only be a matter of time.”

My cock was rock hard in my pants, even though I had tried not to get too caught up in my own fantasy. Jessie and Mari, I noticed, had a look in their eyes that was a funny mixture of disgust and fascination. But the best response was Traci’s. Her face had begun to get a little flushed, and I could see the outline of her nipples poking through her lowcut red cotton blouse. I barely knew this woman, but clearly what I’d said had hit home.

“Well girls, we’ve got a real hornball for a stepbrother.” Traci’s voice was a little breathless. “What do you think, is he as good as he sounds?”
