She "has" a public sex fantasy

"Tell me about your fantasies Tracy, I know you have them, you can trust me with anything." I pull her hand out of her panties for a moment so that she can concentrate on what we are talking about.

"Well, I've always wanted to be the centre of attention for a couple, being their sex toy for a night. I would love to fuck at the top of a mountain."

"And of course there's your public sex fantasy."

Tracy looks right at me, licks her lips as a wicked gleam enters her eyes, "Oh, I fantasise about that all the time. I get bored at the store sometimes, I imagine some handsome stranger coming in here and fucking me senseless in the changing rooms."

She crawls the last few steps over to me, "I don't suppose you'd like to be that stranger?"

In answer, I just reach down and undo me zipper. She eagerly pulls my stiff cock out and begins licking it slowly from the tip all the way down to my balls. The sensation of her mouth on my dick is so amazing that I'm unsteady on my feet. I gently push her away so that I can sit on the small bench in the changing room. Once seated, she eagerly gets back to work sucking me off, pausing every once in a while to pump my cock with both hands.

As Tracy sucks me off, I reach down and play with her glorious tits. They swing back and forth as she enthusiastically works my dick, and the sway of her broad, dark nipples is almost hypnotic. I look down and see she's once again slipped a hand into her panties, fingering herself as she blows me.

Wordlessly, I stand up and pull Tracy to her feet. I motion for her to turn around to face the mirror on the opposite wall, then carefully pull down her white lace panties. I rub my hands over her firm, rounded ass, then slap it a couple of times. Tracy yelps a little each time, but I can see in the mirror that she's smiling.

I line up my hard-on with her wet pussy, then rub it back and forth a few times.

"You want it?" I whisper in her ear.

"Yes! Oh fuck YES!" she fiercely whispers back.

"Tell me what you want."

"I want you to stick that cock in me!" she shouts.

I happily oblige her, and the sensation of my cock sliding into her tight, wet pussy is amazing. As eager as I ame, once all the way in, I pause for a moment, relishing the heat and pressure of Tracy's tight little cunt. Then, gradually picking up the pace, I start to fuck her in earnest. Over her shoulder, in the mirror I watch her heavy boobs swaying as I pound away. Looking up to her face, I see it turn bright red.

Tracy starts moaning and occasionally yelling as I continue to pump her little twat. I feel my orgasm building up in my dick, sensing that i'm about to cum myself, I ask her, "Are you gonna cum for me?"

"Yes," she says. "Oh! oh! Ye-e-e-es!"

Satisfied, I let go and blow my load into her pussy. Pushing in as far as I can reach, I hold it there until my cock is drained and starting to go limp. I withdraw, and note with satisfaction that my cumis dripping from Tracy's pussy. Although I doubt I'll be ready for again for a while, my cock ticks up a bit when she reaches down, dips her index finger into her twat, then turns to me and sucks on it.

"That. Was. Amazing," she says.

Breathlessly, I can only nod in agreement and sit back on the bench. Aware of my surroundings again, I can hear voices from outside the slatted door to the changing room. Peeking out, I see four others in the store, all women, ranging from late teens to early middle age. They're all staring in shock at the changing rooms, wondering if they just heard what they thought they heard.
