At around midnight, I felt my eyelids begin to get heavy. "I think that just about does it for me tonight. I'm tired," I said. "Mind if we go to sleep? If ever there was a night I needed my beauty sleep, it's tonight."

We both brushed our teeth and changed into our night things. Sammy wore a tank-and-shorts set that showed off her slender, boyish figure to perfection. I debuted the negligee I had been saving for my wedding night but was so beautiful I couldn't resist wearing it. It was made of white silk with a lace trim that scooped up my breasts and pushed them together, giving me full, round cleavage. If you looked closely (which I hoped Steve would), you could see the outline of my pink nipples through the sheer fabric.

Sammy gave me a wolf whistle when she saw me. "Here comes the bride!" she said from her side of the four-poster bed. "That's beautiful. Steve won't be able to resist you."

I turned out the light, but neither of us could sleep; we were too excited about the day that lay ahead of us. So we talked some more. Gradually the conversation turned to sex, like it always does when two female friends chat for long enough.

"I think it's so beautiful what you're doing," Sammy said wistfully. "I don't know if I could make that kind of commitment."

"But you and Jez are rock solid," I said.

"Oh, I know that," she replied. "There's just so much I want to do, I'm not sure if you can do it with just one person."

"Like what?" I said, curious.

"I don't know. Just stuff. I haven't experimented that much, and maybe I should. Like, I've never been with a woman, I've never had a threesome, I've never let anyone fuck me in the ass…" I started giggling, suddenly aware of Sammy's warm presence in the bed beside me. I became uncomfortable and excited as vivid visions of my best friend doing all these things ran through my mind before I could stop them.
