Filling In for Strangers

I lifted up on the couch, pulling Ali with me, feeling her breasts glide across my cum-soaked stomach and chest. I shifted positions, allowing Ali to rest her head on my shoulder. She kept her left hand on my cock. "Comfortable?" I asked.

"Yeah. You okay?"

"Fine. Like I said, give me ten or fifteen minutes and I'll be able to go again. It will last longer, too. After that, it might be a while before I can go again."

"I was lucky enough to get something once a week from Dan. You amaze me, Keith."

"Hey, you mentioned you didn't want any risk of weird feelings, or someone pressing for a relationship."

Ali perked up. "What? Is this getting too weird for you?"

"Well, no, but I want to make sure YOU don't get any attachments."

"Oh my, no way. Keith, I just really enjoy sucking your cock."

"Good," I said. "That makes me feel better, but I would like to make one amendment to our agreement."

"Okay?"

"Since you're staying a few days, and since we're both okay with this..."

"Yes?"

"Fuck having limits or quotas. If you want to suck my cock, just ask."

Alison snickered and playfully touched my chest. "Likewise, if you want it sucked, just ask."

We high-five'd, as if we'd done it a thousand times before. For whatever reason, Ali and I were in sync. There was a lengthy pause while we laid together quietly. Finally, I spoke. "So, I have one more request."

"What's that?"

"Let me call you 'Sis.'"

Alison burst out laughing and playfully jabbed me with a forefinger. "You are such a pervert."

I laughed with her and replied, "Yeah, but I think you got me beat."
