Just For Fun

... solid four years of practicing stealthy sex, getting off during what my parents thought had been innocent girly sleep-overs.

"No...that's...it's wrong."

"I know," she moaned. "God, isn't it wrong?"

I knew that as soon as my girlfriend came, she'd realize what a terrible idea it was. She'd call the whole thing off.

I knew that if I told her Justin wanted her to cum, if she were doing it for my brother, she would.

So why wasn't I saying anything?

Matt LeBlanc's face briefly distracted me, and when I tuned back in, Emily was huffing and puffing, and I realized that she'd just cum.

Good thing. Otherwise I would have...I would have...

I would have called my brother.

My own orgasm overcame me at the thought.

"Do you think Justin would fuck me?"

"Of course he'd fuck you," I gasped, trying to push Emily's head back between my legs. "Please...don't stop..."

"I know he'd fuckyou," she said, and I opened my eyes.

Emily was talking about Justin fucking me. This was important.

I turned the show's volume down slightly.

"Of course he'd fuck me," I said, slightly dazed. "What are we talking about?"

"Think about it," Emily said, a dreamy look in her eyes. "Your role is to be his fucktoy, right?"

"Yesss..."

"You're his slut."

"Mmm..."

"You exist to get him hard, to get him off."

I nodded fervently.

"You're just a set of wet holes for his cock."

... there's the taboo of your relationship."

"What's your point?"

"So what amI for?"

I loved being able to talk so candidly about this with Emily. We both knew that none of it was real, that it was just a fetish we shared.

But part of the fantasy was getting into it, treating it as though itwas real. Shaping our lives around it.

And that meant discussing every detail. That was part of the fun.

"He'll beable to fuck you, of course."

"Of course," Emily agreed, without hesitation. She'd slipped up beside me on the bed. I loved being able to smell my pussy on her lips.

Justin would love that as well.

"But I think I'm his slut, and you're his slave."

"Oh yeah?"

"You'll be, like, the maid. Cleaning, taking care of the house."

"Taking care of Justin's property..." Emily murmured.

"Like me."

"Like you," she smiled, and moved her lips to mine.

I could taste myself on her mouth.

"What if we 'accidentally' sent him a photo? Or a video?"

My cunt clenched at the thought, but I shook my head.

"We can't," I said reluctantly. "It is not our role to decide when he takes pleasure from our body."

Emily nodded. The two of us were walking in tandem on the treadmills that we'd had installed in the TV room. We'd decided that we were going to get in better shape.

For Justin.

"Did we do the wrong thing at Christmas?"

I considered the question.

"No," I replied thoughtfully. "No, that was us showing off. We shouldalways show off our ...
