Charissa comes upstairs

My shower was hot and relaxing. I ran through the events of the past couple of hours in my mind. Being seen naked by Charissa on her way to the shower, rubbing sunscreen on her back, playing a hot game of twister, inviting Charissa to sit on my "Santa" lap, enjoying a pretend wedding with a real kiss, and then having a too-close-not-to-be-comfortable visit to the tiny kiddie pool in my front yard. I nursed my boner but was enjoying the thrill of being aroused too much to masturbate fully. I knew that as soon as I blew my load, my brain would resume its role as primary thinker, and I'd realize once again that this was all just innocent fun. As long as my cock was doing the thinking, though, I could still wonder where all this flirting might possibly lead.

I stepped out of the shower, and after drying myself from head to toe, I placed my towel on its rack. I watched myself in the mirror as I rubbed myself almost to cumming--just for the fun of it--and then I stepped into my bedroom.

There was Charissa in a towel, smiling as she enjoyed the sight of my naked body and fully erect penis. She was wearing a thin robe that left little to the imagination! The hem of the robe just barely covered her pussy, and her nipples were clearly evident poking through the soft fabric. I didn't recognize the article from my frequent forays into her wardrobe, so it must have been a pretty new acquisition.

"You're all done?" Charissa asked with an air of complete nonchalance.

"Um," I said, trying to unfog my mind. "Yeah. The shower's all yours."

"Thanks!" she chirped and breezed past me. I was left my with mouth hanging open and my cock dripping precum from the unexpected encounter.

Of course, Charissa characteristically left the door open a crack, and I couldn't help peek as she got ready to shower.

She dropped her robe, revealing her still-hairy pussy and voluptuous D-cup tits. They swayed marvelously as she fiddled with the water from the showerhead, and I enjoyed seeing her nipples in profile when she turned her side to the bathroom door. Her ass was to die for, luscious and soft but with the strength of an athlete, and it was the last thing I saw as she stepped into the shower.

As I said, my cock was thinking more than my brain, so I impulsively gave a sharp knock on the door. "Yeah?" Charissa called over the stream of water.

"Hey, can I come in for a sec?" I asked. I hadn't even cooked up an excuse.

"Of course," she said, "It's your bathroom."

Before giving myself the chance to back out, I stepped into the bathroom.

"It's been a crazy day so far," I said, as if making conversation were the reason I'd entered.

"Yeah!" Charissa replied. "Those kids are too cute."

"They sure are," I said. "And you're really great with them."

"Aw, thank you!" she said through the shower door. I was fixated on the blurred image of her washing her hair, and I struggled to make out any details I could through the fogged glass. "You're really great with them too."

I couldn't believe the babysitter and I were making small talk while she showered mere inches from my hungry eyes and still-throbbing cock.

"Oh, thanks," I said lamely as I realized I was losing any reasonable justification for staying in the bathroom any longer. So I said through the glass, "OK I'm good now, thanks!"

"Of course!" she said happily as I exited the bathroom.

I couldn't think of a reason to stay naked ... so I just got dressed. A few minutes later, Charissa emerged from the shower wearing only her towel.

"That felt good," she said. "You had a good one, too?"

"Uh, yeah," I said. She smiled and just walked by, heading downstairs to get dressed herself.

What the fuck was that? I asked myself. And where is all this going?
