"Kyle?" came Marty's voice. I went back into the bathroom to see Marty, now totally nude, as she adjusted the water temperature in the oversize shower stall. "Come in! The water's fine!" "I...um..." "Don't be shy!" she exclaimed, "Take off those clothes and join me!" I didn't have to be told twice. I skinned off my tee shirt and dropped my shorts and briefs. I had worn no shoes or socks since our return from the mall. As I stepped into the shower stall, the tip of my semi-erect penis brushed against Marty’s hip. That simple touch completed the job of reawakening my frustrated libido. As soon as the shower door was closed, Marty took me by the shoulders and made sure I was wet all over. Then, she turned me so that she was behind me, and began scrubbing my back. Her ministrations were firm yet gentle, and the washcloth's contact with my skin was briskly stimulating. Marty's scrubbing progressed down my back to my butt, and she had no bones about invading the cleft between my ass cheeks. I found her scrubbing of my anus weirdly exciting. She once more took me by the shoulders and turned me around, and proceeded to wash my neck and shoulders, slowly making her way down my front. She avoided touching my privates, but continued as far down my legs as she could reach. Then she dropped the washcloth and soaped her hands directly. Reaching for my hard shaft and my nuts, she gently soaped them up and stroked them. As she did so, she used her free hand to pull my head to hers, and she kissed me deeply, wetly.

Surprised, I hardly had time to return the kiss before she disengaged. "You're going to get to show me what you learned from the book," she said, "but what we didn't discuss was being super clean to begin with; this is why we're in the shower." She backed off and, once more taking me by the shoulders, maneuvered me to a good rinse. Then she handed me a wash rag and said: "Your turn."

Then she turned her back to me. I began by scrubbing the nape of her neck and her shoulders, then worked my way down her back as she had done with mine, making sure that I paid proper attention to her anus, as she had tacitly taught me. Without turning her, I pressed my body against her back, nestling my erect cock between her cheeks, and proceeded to reach around and wash her front. I was particularly gentle with her breasts, scrubbing one with the rag, fondling the other with my fingers. As I did this, Marty threw her head back and rested it on my shoulder, murmuring moans of pleasure.

"You're a quick...mmm....and...mmm...intuitive learner." she said between sighs and moans. The compliment encouraged me, and as my hands approached her crotch, I did away with the wash rag, and gently soaped up her vulva, letting my slick finger slip in between her pussy lips. Marty gasped lightly when I touched what I felt sure was her clitoris, confirming that I had indeed found my target. I felt Marty jerk slightly as I gently fingered the little nubbin I had found. I continued the mild friction down there for a minute or so, eliciting ever heavier, ever louder sighs and moans, along with spasmodic movements of Marty's pelvic area. She stiffened finally, then relaxed, almost falling, held up only by my embrace.

Marty turned to face me, and signaled her desire for a kiss, rapidly shifting her gaze between my eyes and my mouth. I took the hint and complied, first nibbling at her lips, then invading her mouth with a playful tongue. The kiss lasted for about a half minute. "That was nice..." she said, almost whispering.

We disengaged, and Marty, obviously still in control, turned the water off. "I think we're both clean enough." she laughed. We stepped out of the shower and Marty handed me a towel. As I began gently drying her off, she took another and vigorously dried her hair. By the time I was down to her ankles, she was brushing her shiny mane. Done, she reached for a third towel and began drying me off. She spent a little extra time at my crotch, reminding me of my so-far frustrated libido.

"You're teasing me..." I said. "Yup!" she replied tersely, a twinkle in her eye.
