I had picked out a skirt and blouse to try on. On the way to the changing rooms in the back of the shop I saw a good-looking guy about 20 carrying some jeans.

I went in the end cubicle, and noticed that the curtain of the cubicle opposite mine wasn’t closed all the way. I guess I didn’t close mine all the way either, because I heard a noise from that cubicle and looked in the full-length mirror and I saw the good-looking guy leaning against the wall while he peeled off an obviously too-tight pair of jeans. When he bent down, I got a fantastic view of his firm butt in tight white briefs. His T-shirt hinted at a chiseled torso.

I found myself just standing staring. Finally I snapped out of it and got on with trying on the skirt and blouse. When my skirt dropped to the floor and I bent down to pick it up, I heard a gasp. I realized the guy was seeing the large portion of my butt revealed by my high-cut cotton panties along with my long legs. He seemed to like what he was seeing!

I began to unbutton my blouse, knowing that he’d be able to see the skimpy bra containing my breasts and the front of my panties. I sneaked a look myself and saw his hand move over the front of his briefs. I looked up, and suddenly his eyes met mine in the mirror! I adjusted my position slightly and gave his image in the mirror a naughty smile. My gaze traveled down, and I saw a big bulge pushing his briefs out. I felt moistness between my legs. Me, playing with a kid half my age!

After a while I saw a twitch in his briefs. I slowly undid my remaining buttons, slid my blouse off and hung it on a wall hook, then dropped my arms to my sides, allowing him to just look at me. My heart was beating so hard, I was amazed not to see it bursting out of my chest.

I was very wet now, and there wasn’t much of me that the guy couldn’t see. I work hard to keep in shape, and hoped he was admiring my taut frame with my boobs pushed way up by my bra, my reasonably flat stomach and all that was revealed and hidden by the high-cut panties. If he looked hard enough, he might see the dark damp spot growing larger by the minute.

I couldn’t believe I was doing it, but I held out my arms and turned around in a circle, making sure he had a chance to see everything. Facing the mirror again, I looked at him and raised my eyebrows in question. He gave me a thumbs-up!

Beginning to enjoy myself, I teased my breasts with my fingertips pinching the nipples through the bra. Into the mirror I ran my tongue sensuously over my lips. I lowered a bra strap and freed a boob. I’ve always been proud of my round tits with their slight-ly upward-pointing nipples. I imagined my young stud clamping his hungry mouth over one of them.

To egg him on, I pointed at his crotch in the mirror. He didn’t get my meaning. After brief thought I made a circle with my thumb and forefinger and did a few up-and-down motions. His eyes widened. Smiling, he eased his briefs out and over his penis and down his legs. As he straightened, his penis emerged from his groin at an angle, then curved gracefully upward, long and thick. I saw it throb with his pulse as he posed briefly. My pulse was racing. He curled his fingers around his shaft and stroked slowly up and down, up and down. I clenched my pussy in rhythm with his strokes.

It was my turn. I pulled my other bra strap down until both breasts were exposed. Keeping my eyes fixed on his hand moving up and down his shaft, I massaged my breasts, rolling the nipples between my thumbs and forefingers. He was stroking himself, a few quick strokes then a few long ones, back and forth. Each time, I saw the head disappear into his grip, then reappear.

I dropped a hand to my panties and caressed my mound, sliding the middle finger in the space at the top of my thighs. As he’d shown me his, it seemed only fair to slide my panties down to my thighs so he could see all of my butt and my trimmed mound with its small bush of curly hairs. Again I turned full circle to give him a view. He released his shaft and did a similar turn, his shaft bobbing as he moved. When he was back facing the mirror, he resumed stroking.

Again I put my hand over my pussy, and started small up-and-down movements, then slid a finger in the gap between my legs, then back, teasing my clit slightly each time. With my other hand I tugged at a nipple. Normally I would close my eyes while teasing myself, but I wanted to watch the beautiful young man watching me.

While his stroking continued, his hips moved a bit. His pace quickened, raising my excitement. I moved my legs wider apart and leaned forward to improve access between them, also exposing more of my butt. My admirer might even be able to see my pussy lips — and the added arousal my fingers were causing.

My hand was moving faster. I was pressing harder on my clit, and alternating between slipping a finger in my pussy and just teasing around the entrance. My lover’s hand was also moving quickly. I kept staring at his hand pumping away. Suddenly he stopped, and gripped the base of his cock. I bit down on my lip as my fingers brought me closer to the edge.

I nodded to him in the mirror, and as I moved my eyes back to staring at his hand on his cock, I imagined him standing behind me plunging it in me. He managed only a few more strokes before his hips surged and he burst. I imagined he’d just pulled out of me and the come he was spewing on the mirror was spewing all over my ass.

That pushed me over the edge. I put a hand to the wall to keep from falling and bit my lip to keep from moaning aloud. I rested my hand over my pussy with the palm over my mound and a finger at my slit. I moved the finger around my lips, reveling in the creamy wetness. Then, recalling how it turned on previous lovers, I lifted my hand to my mouth and took each finger between my lips, licking off my juices. I was rewarded when the guy lifted his knuckles to his lips and licked them clean!

Watching me clean my fingers while he licked his knuckles seemed to turn him on. His erection, which had lessened only slightly after he came, was hardening again. In what seemed like seconds it was pointing to the sky! I was tempted, but decided I didn’t need such entanglements.

I quickly put my bra and panties back on. Abandoning any thought of trying on the blouse and skirt, I put my own clothes back on and left the changing room. The assistant said something as I walked past, but I didn’t make it out. I just shook my head and handed her the token and clothes.

I made my way to the exit, looked around to make sure the beautiful boy wasn’t following me and walked out. I made my way to a nearby coffee bar and, feeling guilt mixed with exhilaration, tried to make sense of what I had just done. I’d never done anything remotely like it. I glanced up and saw the boy walking by. I looked down at my coffee in case he looked in, but he didn’t.

But as I relaxed with my coffee, I acknowledged how much I’d enjoyed my adventure. And I started planning how to have another one.
