Peeking carefully around the corner to make sure Rachel wasn't still there I stepped quickly through the doorway into the shower area. There, framed by the curtains of individual shower stalls, was Rachel. Her back to me and her body fully exposed. The steam seemed to form a ring around her glistening skin and I had to remember to breathe. She brushed a hair over her ear as she turned to enter the shower and as she did I was sure that she glanced over to make sure I was watching. Of course I was, I didn't even dare to blink until she closed that damn curtain. I relived the moment over and over as I willed my feet to move in her direction. I was sure she'd nodded when she'd glanced at me; it couldn't have been an invitation, could it?

As I got to the end I realized what it was. The stall next to hers was open. The stall wall between us was a foot off the ground so I could see up to her ankles as she showered next to me and if I stood on the tips of my toes, if I dared, I could probably peak over at her. I didn't dare do that. If I were caught I didn't know what I'd say.

Instead I closed my own curtain and started to roll the very wet tights down my body. They fell to the shower floor where the run off from Rachel's shower got them wetter and I was far more careful as I removed the top. I hung them both up on the hook just outside the curtain, resisting the urge to peek through the little crack in Rachel's curtain, before turning to the shower knobs.

I knew that I needed a hot shower to relax my muscles but the old cliché of a cold shower kept running through my mind. Luckily the showers at the gym were the type that didn't really provide an option. No matter how I manipulated the knobs the shower stayed the same lukewarm spray.

Eventually I gave up and just accepted the water cascading over my body for what it was. There were dispensers in the shower with body wash and shampoo if I hadn't brought my own, and I had forgotten. This allowed me to lather my hair and try to drown out the sounds of Rachel so close, so naked.

"By the way," her voice rang out making me jump, "you aren't planning to go back to that boy's outfit next session are you?"

"I, uh, I might. This one got pretty wet, sweaty, and I don't really have anything else appropriate."

"Well, we could go on a little shopping run if you want, tomorrow maybe, or after our session Thursday?"

"I could maybe go out tomorrow after work."

There was no maybe about it. I had no friends and no plans. Still, I wanted to play coy.

"Great, few tops, maybe some shorts?"

Her voice seemed too clear, too close, I peeked my eyes open despite the soap and found her looking down on me from over the stall. Screaming, I fell onto the floor.

"Hey, wow sorry to startle you. Are you okay?"

My butt hurt from the fall but I hadn't hit my head. It was foolish, more a drop to preserve my modesty than a slip, and it hadn't achieved its goal. My legs ended up apart and she could see more of me than if I'd stayed standing. "I'm fine, sorry, I'm such a klutz."

"Here let me help you."

"No! No really I'm fine, thank you."

I tried to climb to my feet to prevent the impossible situation of us being naked together in a confined space. I managed to get up but it didn't matter. Rachel had slipped in behind me.

"I said I didn't need help!" I cried, hugging my breasts and turning my back to her in a sad attempt to conceal what she'd already seen.

"I'd rather make sure than have to do an incident report."

"Get out of here!"

She caught my shoulder before I could turn and shove her then leaned in close, right up to my ear.

"Do you really want that?"

She whispered it so softly I was sure I'd imagined it but I could feel her hand, her peppermint sweet breath. She'd really said it.

"N-no" I managed.

"Good, now let me see your butt."

The hand on my shoulder pressed forward, making me lean against the wall. The other hand moved to my butt, gently touching near the tailbone where I'd fallen. Finding no bruise, no evident pain it moved lower.

"Is this where you spank me?" I whispered it but she heard every word.

"If that's what you want."

She didn't wait for further permission. Her hand slapped my butt. That's really all it was, a slap on the butt and yet it was so much more. She did it again, a touch harder, and again. I couldn't speak, couldn't catch my breath. My body was on fire.

"Please don't, stop please, I'm going to..."

I was babbling, losing my mind as she began to spank one cheek then the other with a lifting strike that drove me wild.

"Be. More. Careful. In. My. Shower."

"Yes coach!" I managed in a panicked groan.

"Good girl" she said, and with the gentlest motion she slid her hands between my legs, stroked my clit for just a moment and penetrated me with two of those thick, strong fingers.

I was undone. I'd never accomplished anything like this with my own hands. It was all I could do to keep from sliding back down to the shower floor. Her fingers stayed in me until the orgasm had passed then she pulled them away. No kiss or cuddle. She'd done it and then she'd been done. For now.

"I'll meet you at the library at six," she whispered in my ear before leaving me there, a puddle of tongue-tied joy, to rinse my hair.
