Most people think you're a rumour, but every pervert in town at least knows the story.

If you go to the mall, there might just be a gorgeous girl sat on a bench by Victoria's Secret, in a tiny pink dress. The stories say that if you give her a good enough gift from the nearby lingerie store, she'll thank you and walk off to use the little restroom on the other side of the mall. If you go with her to the last stall of the mens room, she'll "reward" you. And if you're lucky enough to get under her dress, she'll insist you fuck her in the ass. Because there's no pussy under that dress..

Today, I took the plunge. Worst that happens, I figure, is that I embarrass myself in front of a random woman and look a bit weird. The best that can happen.. well it's worth it. My heart was pounding as I walked through the mall and sure enough, there you were! Pink dress, without a bit of slack over your tight body. Long blonde hair and blue eyes. You were gorgeous.

Nervously, I entered the mall, dark box clasped in hand, filled with a smouldering set of dark, lacy underwear. I walked over to the bench and held out the box.. "I thought you might like this.." I said. You smiled at me. "Thanks Papi..." you said to me, in a perfect sing-song voice. "I'm just going to pop to the little girls room" you said with a wink.

You then gave me an innocent smile and held out your hand. We walked across the mall without any bother, with people just assuming you were my girlfriend We occasionally made eye contact and you would give an innocent giggle and look forward again. Finally, we reached the bathrooms, and as usual, they were filthy. Nobody came in here unless they didn't want to be disturbed. Graffiti covered the walls. I clasped your hand as we walked to the end stall and locked the door behind us.

The look in your eyes changed. Took on a mischievious glint. "Oh, Papi... I'm not sure I need to pee anymore.." you said, sidling up to me and pressing your slim body against mine. But I was done playing games. I undid my belt and dropped it to the ground. As my cock sprung out of my pants your full, soft lips, glossed a soft pink, formed a perfect circle. "Papi you big Perv!" you said, giggling and dropping to your knees, "I love it.." you purred, voice changing to a purr, lower than your usual sing-song.

Your soft, dainty hands wrapped around my cock and started to stroke, expertly moving up and down whilst twisting, teasing every bit of pleasure you can out of me. "Mmmm are you a dirty man Papi?" you cooed up to me, "Do you like it when naughty little sissies like me touch your big cock?"

As you said "cock", your hands left my dick and yanked my pants down around my ankles, letting you press your face under my cock, pressing your tongue against my balls while you continue to jerk me off. Sloppy, wet noises fill the cubicle for a few moments as you lose yourself in my ballsack, before pulling away, circling your tongue ever so slowly around the very tip of my cock, precum seeping out onto it. Then you stop. "You're a big dirty perv Papi..." you teased, but I was too lost in the sensations of your hands working my cock to care. "But that's okay.."

You lifted your skirt, revealing a surprisingly large cock for your slender, feminine frame, sticking out of a tiny thong, covered in precum. "Big dirty pervs get my clit pumping.." you purred, before smoothly wrapping your lips around my head and sinking the first few inches of my length effortlessly into your throat. From somewhere you pulled out a phone, pulled the closest face to a smile you could with a mouth full of cock and made a little peace sign with your spare hand. Before I knew it the selfie was done and you were back to concentrating your attention on my cock. Your blue eyes fixed to mine, alternating between an innocent, sweet little gaze, and the lusty, hungry look of a total slut.

Then I felt something press against my asshole, and realised you were forcing two fingers up there! "Whoa, hey there!" I started, before you pulled back and interrupted me. "Relaaaax Papi... Let me do my job.." you winked at me. "You're gonna love this.."

You pushed your fingers deeper, making me grunt as I tried to adjust. Then, without any warning, you impaled your throat on my cock, burying your nose in my pubes. For a few seconds, I forgot all about your fingers, a hot mess of moans and profanity as your tiny throat twitched around my sensitive dick. By the time I realised they were still there, you were thrusting in and out, matching the rhythm to each thrust of your head forwards. And now I was used to it.... it felt good. Each thrust of your fingers ignited a pleasure somewhere deep inside me, and I knew I didn't have much longer.

You pulled back, leaving a string of spit dangling from your chin and lips to my cock. "Is my big pervy Papi gonna cum all over my face now?" you asked, in your faux-innocent voice once again.

Wordlessly, I grabbed your face and slammed my cock into your mouth, drawing a surprised squeak from your lips as I thrusted and thrusted and thrusted and.... "FUCK!"

I pulled back, exiting your mouth just in time to shoot a huge rope of cum across your lips, cheek and forehead. Your hands worked my shaft eagerly, little coos and pleased giggles escaping your lips as another rope squirted onto your tongue and teeth, then another.... then another...

By the time I was finished, you were soaked with jizz.

"Oh, Papi you're my favourite dirty old perv in the world!" you giggled, rummaging through the hello kitty purse for your phone, showing me the contents in the process: lip gloss, vaseline, condoms and a butt plug..

You snapped a few selfies. One of your mouth open wide with surprise, one with your mouth filled with a pool of cum and one with you comparing my cock to the size of your forearm.

You reach into your top, into your bra, and pull out a card with a hyperlink and the same "Sissy Slut Samantha" on it.

You unlocked the door and went to the sink to clean up the cum. "Go to the link, Papi... you'll see".

And with a wink you were gone.

I got a text later.

"Hey there Papi! I've made you an account at sissysac.xxx . It's where all the other pervs go to look at pics and vids of me. I made you an account so we can keep in touch.. here are the details ;)"

I entered the details and was met with my account. "PervyPapi69" was the username, and the profile picture was the shot of my cock next to your forearm. Another message flashed up, this time on your site.

"Hey Papi! Had fun today, wanna meet up tommorow. Go to this address and we'll have another date ;)"

Then you sent a link to a post on your profile..

"Me and @PervyPapi69 had a great time in the stalls today! He's my favourite #PERV in the world! #hung #cumshot #cumslut #perv #bigcocksareforlittlegirls #slutswhodontswallowarentsluts

and there were all your selfies..

When I pulled up at the address, I was in the middle of an empty industrial plot in front of an unsigned warehouse.. what did you have planned?
